MESSAGE

There has been a remarkable progress in terms of economic growth which has brought

immense benefits to the people. The poverty has fallen and industrialization has

accelerated. This process, however, creates significant challenges for managing pressures

on natural resources and the environment necessary for sustaining these accomplishments.

Realising these challenges, Government of Gujarat has taken number of steps which

called for a fundamental shift in the priority given to the environment and their regulatory

approach to environmental management.

This report on Ecological Profile of Coastal Talukas along the Gulf of Khambhat is a

contribution to the process of detailing and implementing this strategic vision of the

Government of Gujarat. It is the product of a continuous process of primary data collection

from the field as well as frequent personal contacts with allied sectors for the collection of

secondary data. Efforts have been made to analyse and correlate the available information

with the actual field conditions.

I am sure this document will come in handy to various stakeholders including decision

makers in striking a balance between the economic growths and protecting our biological

heritage in the process of achieving a sustainable development.

I congratulate Gujarat Ecology Commission for publishing this document which would go

a long way in conserving the coastal natural resources in times to come.

PREFACE

The state of Gujarat is predominately an arid and semi-arid region. But, due to its

geographical position and topographical variations, it is quite rich in its ecological wealth

ranging from grasslands, forests (thorny scrub to canopy forests), wetlands, saline deserts

and the coastal systems. However, most of these ecological systems are facing threats

of different anthropogenic pressure. Considering the length and width of the state,

and spatio-temporal variability of different resources, development of a computerized

information system is the most appropriate answer for cost- effective planning and

management of various natural resources of the State.

As part of the creation of ecological databank, commission has launched project

entitled preparation of Taluka level Ecological Profile with financial support of Forest &

Environment Department, Govt. of Gujarat. As a part of this exercise GEC had prepared

comprehensive ecological profile of 19 talukas located around Gulf of Khambhat. The

taluka includes Umbergaon, Jalalpore, Chorasi, Olpad, Hansot, Valsad, Jambusar, Vagra,

Dhandhuka, Bhavnagar, Ghogha, Talaja, Mahuva, Rajula, Jafrabad, Una, Kodinar, Gandevi

and Khambhat.

Main objectives of this exercise are, to collect data/ information at taluka level on those

parameters which have certain correlations with the ecological condition of the region from

available secondary sources. Its also aim to analyzed available primary (on biodiversity) &

secondary data to put in GIS domain to prepare digital ecological profile of each taluka.

For the collection of primary data, field survey was undertaken by GEC team as well as

for the secondary data collection, majority of data were collected from offices of various

Government departments and agencies. The data were decided to organize, first into a

simple database, and later be transported into GIS platform.

During the survey of biodiversity in selected coastal talukas around Gulf of Khambhat,

430 plant species were recorded, out of these total species, 91 species were woody,

201 species were herbaceous and 39 species were climbers while faunal diversity have

Page 6: ECOLOGICAL PROFILE OF COASTAL TALUKAS AROUND GULF OF KHAMBHAT · AROUND GULF OF KHAMBHAT Gujarat Ecology ... Chorasi, Olpad, Hansot, Valsad, Jambusar, Vagra, Dhandhuka, Bhavnagar

28 mammalian species, 215 bird species, 32 repti lian species. Parameters like climate,

human populati on, land use, agriculture and irrigati on, livestock which are related with

ecology were also collected by various sources. In the case of secondary informati on,

GEC tried to collect informati on of last 20 years to correlate the primary & secondary

informati on to visualize the trends of ecological changes during last 20 years in each

selected taluka.

To complete the exercises, I dedicate my grati tude to all the departments and agencies for

their help by providing secondary data. The Gujarat Ecological Commission appreciates

the support and cooperati on of Centre for Environment & Social Concern, Ahmedabad

to provide their services in fi nalizati on of appropriate methodology and guidelines to

collect primary data, as well as in conti nuous support throughout the enti re exercise.

I also appreciate the study team of GEC for their eff orts to bring out with this report.

This report is aimed at sensiti zing, apprising and familiarizing laymen and specialists as

well as managers and policy makers alike, the issues of biological diversity and ecological

situati on of Gujarat. I hope this report will be useful in planning for diff erent government

and non government agencies.

EXECUTIVE SUMMARY

Due to geographical positioning and distinct physical and oceanographic

characteristics, the 1600 km long coastal tracts of Gujarat can be divided into four

sub-regions. These include (i) Gulf of Kachchh (ii) Saurashrtra Coast (iii) Gulf of Khambhat

and (iv) South Gujarat Coast. Ironically, most of these coastal systems are vulnerable to

various anthropogenic activities including rapid industrialization and coastal infrastructure

development projects (like ports, oil terminals etc.), jeopardizing both ecological as well

as livelihood securities along these regions.

Development of a computerized information system is critical for cost- effective planning

and management of various natural resources of coastal tracts of the State. Keeping

above in view, Gujarat Ecology Commission (GEC) plan to collect and organize ecological

information of all the coastal talukas in the State . As a part of this exercise in first phase

GEC had initiated preparation of ecological profile of 19 coastal talukas adjoining Gulf of

Khambhat. The selected talukas include Umbergaon, Jalalpore, Chorasi, Olpad, Hansot,

Valsad, Jambusar, Vagra, Dhandhuka, Bhavnagar, Ghogha, and Talaja. Thus, this study has

been undertaken with following objectives:

1. To collate data/ information at taluka level on those parameters which have certain

correlations with the ecological condition of the region from available secondary

sources

2. Undertake field surveys in ecologically important sites to collect data on important

biological parameters at taluka level.

3. To organize both primary and secondary data in GIS domain

4. To prepare ecological profile of each taluka

To achieve the above objectives, two pronged approach was adopted: (i) the field surveys

to collect information about flora, fauna and their habitats and, (ii) collation of relevant

secondary data which are required to build up ecological profile from various sources. The

collected data were organized, first into a simple database, and finally be transported into

GIS platform. During field surveys, a total 1339 sample plots were surveyed for recording

vegetation and habitat parameters, while 447 points were surveyed for faunal records.

During the survey, both direct and indirect evidences of wildlife were recorded. Wherever

possible, photographic evidences were also collected for plant and animal species.

A total of 430 plant species were recorded during the survey. With the record of 231 and

221 species, the Una and Mahuva are the two phyto-rich talukas, respectively. Survey also

revealed the presence of 28 mammals, 215 birds and 32 reptile species from the surveyed

coastal talukas.

As part of secondary data collection, time series data on parameters like rainfall, human

population, land use, cropping area, irrigation, livestock etc, which are related with well

being of local ecology were collected. Recent trends indicate a decline in the average

annual rainfall in 10 talukas. Especially, high percentage decline in rainfall was recorded in

talukas like Kodinar (21.3%), Mahuva (18.6%), Jambusar (18.8%) and Rajula (17.5%).

The data were also analyzed to show trends in human and livestock population and other

parameters like area under crop cultivation, irrigation, forest cover etc. Between 1997

and 2003, on overall basis, increase of about 6.4% and 9.4% was observed in cattle and

buffalo population. But, in Jafrabad, Rajula and Gandevi talukas declining trends are

recorded. While, human population was found rising in the study talukas varied growth

trajectories are reported. In terms of poverty, however, Valsad and Umbergaon talukas

are top in the list with 24 and 19.5% of total population as BPL, respectively. The large

BPL population indicate higher degree of dependence on common natural resources like

forests, pasturelands etc.

Among the major landuse categories, while it was found that forest areas get declined in

most of the talukas, the maximum decline was recorded in Una taluka, where between

1980 and 2005 more than 30000 ha forest land was found converted into barren category.

Pasturelands are also declined in a few talukas like Dhandhuka and Rajula. Overall, the

fallow lands in these talukas are also declined. Reasons for such shifts in landuse categories

and their driving forces need to be explored.

During the same period, net sown area in Dhandhuka taluka recorded massive decline

of about 73200 ha. However, in talukas like Bhavnagar, Kodinar and Valsad the same was

found increased, indicating improvement in irrigation infrastructure in these talukas. Data

also suggests that on overall basis, the total area under irrigation was increased over the

years.

During 1991 and 2004 there were major shifts in cropping pattern. Accordingly, area under

traditional food crops like cereal, pulses and oil seeds were declined, while cultivation of

cash crops like sugarcane, tobacco etc. were on rise. Jafrabad, Gogha, Olpad, Mahuva and

Hansot talukas recorded a high percentage increase in cash crop area.

While this report recorded some interesting trends and changes in various land use

categories, cropping patterns, irrigation etc. the data needs further exploration. More

intensive and systematic ecological survey will also help understanding the floral, faunal

abundance and distribution. The report also suggests various measures to improve the

quality of data collection and analysis in second phase of the study.

Introduction

1.1 RationaleofStudy

Integrated resource management approach has been recognized as an important aspect

of planning at the regional level. In any such resource management practice, the first

step would be the accurate and periodic resource base inventories by understanding

the spatial integration of resources in the area. The modern management is basically

a decision science and a resource manager needs periodical evaluation of different

resource attributes to examine the capabilities of a particular land area, before concurring

to any decision. To conduct this evaluation one needs up-to-date data on resources

and an efficient system for storing, retrieving, and analyzing these data. Computerized

Geographical Information System (GIS) is one such system available to effectively handle

the above.

The State of Gujarat is predominately an arid and semi-arid region. But, due to its

geographical position and topographical variations, it is quite rich in its ecological wealth

ranging from grasslands, forests (thorny scrub to canopy forests), wetlands, saline deserts

and the coastal systems. However, most of these ecological systems are facing threats of

different kinds originated from almost all the above-defined pressures of anthropogenic

nature. Considering the length and width of the state, and spatio-temporal variability

of different resources, development of a computerized information system is the most

appropriate answer for cost- effective planning and management of various natural

resources of the State. Keeping this in view, Gujarat Ecology Commission (GEC) is aiming

to prepare spatial and non-spatial database of key ecological parameters that can be used

in better land use planning, wasteland development, environmental and social impact

assessment of developmental projects, conservation of rare and endangered biodiversity

including flora and fauna and their critical habitats, identification of ecologically sensitive

areas, climate friendly energy development etc.

Gujarat, a maritime state, endowed with about 1600 km. long coastline which is

approximately 21% of the entire Indian coastline. Gujarat’s coastline is uniquely

heterogeneous in a sense that within the 1600 km long coastline it has been broadly

divided into four geo-morphologically and oceanographically distinct sub-regions. These

include Saurashtra Coast, South Gujarat Coast and two gulfs viz. Gulf of Kachchh and Gulf

1. INTRODUCTION

Introduction

of Khambhat (or Cambay), covering about 60% of the State’s coastline. Importantly, out

of three Gulfs in the country, two are situated in the Gujarat state. In direct dependency

term, total population of more than one million people in about 550 villages reside along

the coast and extract its resources.

Ironically, all these coastal sub-regions are facing inherent challenges of economic

development and associated environmental degradation. They are vulnerable to various

developmental activities including rapid industrialization and coastal infrastructure

expansion projects (like ports, oil terminals etc.) as part of strategic economic development

policies (like promotion of SEZ, SIR etc). These seriously alter the land-use system of the

region which in turn influence related sub-systems like soil, agriculture, livestock, fishery,

hydrology, bio-diversity etc., jeopardizing both ecological as well as livelihood securities

along these regions.

Keeping above concerns in view, Gujarat Ecology Commission (GEC) plans to collect and

organize ecological information of all the coastal talukas in the State. As a matter of fact,

explicit goal of this exercise is to facilitate creation of a decision support system through

up-to-date inventorying of different parameters that are associated with the health of

coastal ecology, their analysis and feedback. Thus, diverse sets of data compiled and

outputs generated of this exercise will be useful to various stakeholders including policy

makers, planners, researchers and civil society organizations.

1.2. Scope&LimitationsoftheStudy

As described above, GEC explicitly aims to prepare an environmental decision support

system for promoting sustainable development in coastal regions of Gujarat. The first

step towards the achievement of above goal was, however, initiated for the coastal region

along the Gulf of Khambhat. Thus, in the initial phase of this program, 19 talukas along

the Gulf of Khambhat were chosen for preparation of their ecological profile. Considering

the enormity of the task, the above were attempted and achieved in two contiguous

years viz. 2008-2009 and 2009-2010.

It is important to mention here that internet search reveals that there is no any formal

definition of “ecological profile” available, and the term is used differently in different

contexts. Simply, therefore, in the present context, the term ecological profiling is used

to present the state of different parameters which had some linkages with the ecology/

environment of the coastal talukas. In a sense this exercise of “ecological profiling” is

providing baseline data of some of the prioritised indicative parameters of sustainable

coastal development (like climate, flora/fauna, land use changes, developmental

Page 16: ECOLOGICAL PROFILE OF COASTAL TALUKAS AROUND GULF OF KHAMBHAT · AROUND GULF OF KHAMBHAT Gujarat Ecology ... Chorasi, Olpad, Hansot, Valsad, Jambusar, Vagra, Dhandhuka, Bhavnagar

Introduction

scenarios like industries, energy demands etc.). The baseline data is mostly of different

time period (in other words the time-series data), collected from different existing

sources (secondary data).

In view of above, this study simply attempts to (i) collate relevant data from various

agencies and also by undertaking limited primary field surveys, and (ii) analyse collated

data to record key spatial and temporal trends in them. However, considering the fact

that the secondary data were coming from various sources and thus are not matching in

their periods and, in many cases, in their administrative scales (like talukas and district),

the framework for integrated analysis was quite restrictive. Thus, in most of the cases,

the analysis is limited to single parameter. Actually, in a broad sense, this work is a kind

of scoping study, which aspires for knowing approximate trends in various parameters

and aims to identify critical talukas along the Gulf of Khambhat. Contextually, this study

neither attempts to record the “proximate and root/policy causes” of above trends nor

it explores various “ecological/environmental and socio-economical effects” of those

trends. Considering the limited time and financial resources available for the study, no

detailing of data/information had been attempted below the taluka level. Therefore, in

order to gain deeper insight on various “causes and effects”, series of follow-up case

studies need to be separately initiated.

On the aspects related to flora and fauna, despite constraints of time to undertake

statistically rigorous data gathering system (that include sufficiently large sampling and

covering different seasons) as well as non-availability of studies on flora and fauna at taluka

level, the study attempts primary field surveys in each taluka. The information generated

through such surveys need to be considered as representative not as comprehensive.

1.3. Objectives

Based on above understanding and to achieve the overall agenda of sustainable coastal

development, the present study defines following major objectives:

1. To collate data/ information at taluka level on those parameters which have certain

correlations with the ecological condition of the region from available secondary

sources

2. Undertake field surveys in ecologically important sites to collect data on important

biological parameters at taluka level.

3. To organize both primary and secondary data in GIS domain

4. To understand the trends and the state of different indicative parameters of

sustainable development in coastal talukas

Introduction

1.4. ReportPresentationandImportantCaveats

The report is mainly consisting of five sections. Following this introductory chapter,

a detailed description of approach and methodology, adopted during the study, is

presented. The taluka wise data presentation and their analysis is actually divided into

two separate chapters. Chapter 3 provide detailed account of status of flora and fauna

and their habitat in each taluka. Chapter 4, however, presents summaries and trends

in various climatic and socio-ecologically linked parameters. Using these parameters,

this chapter actually identifies key socio-ecological changes occurs in coastal talukas

(needless to say, without exploring the causes and the effects) along Gulf of Khambhat.

The last section briefly presents key conclusions of this entire exercise. Relevant raw as

well as analysed data are presented in the Annexures, at the end of the document.

While the report is prepared with an aim to use it by wider section of the society, yet it is

important to highlight here the key limitations of this exercise. It is important for avoiding

inappropriate use and interpretation of different data sets and their trend etc. Thus,

following qualifications are required to bear in mind before using this report for various

planning and research needs:

1. Most of the data are collected from different Government Department/ Agencies,

using official channels. While the care has been taken to check the authenticity of

the data values, the final responsibility of the data lies with the concerned agency/

department.

2. In many instances, the data are not up-to-date, and thus the derived trends and

other summaries need to be used carefully.

3. The time-series data provided by different agencies does not able to disaggregate

the values, keeping the reorganization of talukas in perspective. This is considered

important especially in the situations where sudden changes are recorded in the

values and thus the trends. User of this report need to identify and highlight this

fact before using it.

4. The primary data on floral and faunal assemblages is not complete and /or

comprehensive. As a matter of fact, a taluka level inventory of biodiversity is

quite an ambitious task. Due to resource limitations, the study did not explore the

previous records and studies and thus not able to generate complete range of floral

and faunal assemblage for each taluka. Also, seasonal variations in floral and faunal

status also not explored. Nevertheless, the data presented in this report need to

be seen in conjunction with other existing knowledge about key species as well as

sites.

Introduction

5. It is important to reiterate that the data and their trends may not be used directly

for drawing conclusions about various “causes” and “effects”. Rather, the trends

need to be used for indicating some interesting ‘happenings’ in some parameters

and/or talukas.

1.5. OverviewtoGulfofKhambhat

India is bestowed with three gulfs viz. Gulf of Kahchchh, Gulf of Khambhat and Gulf of

Mannar. Gujarat, one of the longestest maritime states of India prides of taking up two

gulfs, Gulf of Kachchh and Gulf of Khambhat respectively within its boundaries. Both

the gulfs owe their own picularities in terms of physiography, hydrography, biodiversity

and the surrounding coinfluences. Gulf of Khambhat is oriented with its tail towards the

north and mouth towards the south.

The Gulf of Khambhat, covering about 3,120 sq km, is situated between 21°00’

N and 22°18’ N latitudes and 72°15’ E and 72°45’ E longitudes. Gulf of Khambhat

owes its own peculiarities in terms of tis geomorphology, hydrodynamics and high

tidal amplitude. The funnel like structure of gulf with wide mouth and narrow

head (width 200 km at mouth of Gulf terminating to ~6 km at the tail). This feature

makes the Gulf second in the world in terms of tidal amplitude. Several reivers including

major rivers of Gujarat like Narmada, Tapi, Sabarmati and Mahi opens in Gulf draining

down water and alluvium to the gulf and coastal area.

The wide range of variation in population density and growth reflects the heterogenous

status of natural resource base, agriculture and other economic activities/ development.

Gulf, withing its adjoining talukas supports an approximate population of 4.3 million as

per the 1991 census.

Introduction

Since histories, Gulf of Khambhat has marked its presence in terms of prosperity

depending on the glorious ports and development based humansettlements. Gulf of

Khambhat, covering 400 km long coastline forms about one fourth of the total coastline

of the state. Dahej and Ghogha has been one of the important ports since histories

marking their presence in Gulf of Kahmbhat.The area around Gulf of Kahmbhat different

spreads over 19189 sq.km in nighteen talukas. The adjoining area has been emerging as

industrial development zone. The region from Vadodara to Vapi has been considered as

a ‘Golden corridor’ in terms of industrial leap. The ports and transportation facilitation

of Gulf has attracted various industries to develop on the fringe. No doubt, the same has

changed the socio-economics of the area as well as the direct or indirect changes in the

landuse pattern.

Looking to these piculiarities of Gulf, the study was aimed to build up a baseline preliminary

stutus on ecological data with the correlated data in the 19 talukas surrounding the Gulf

of Khambhat.

Approach and Methodology

Considering the above objectives in view and juxtaposed those with the availability of time and resources, following approach was adopted which involved Taluka selection, Collection of secondary data and collection of Primary data.

2.1 TalukaSelection

The aim of the study was to outline the biotic status of talukas bordering Gulf of Khmabhat. During entire phase of the study, a total of 19 talukas along the Gulf of Khambhat belonging to 09 districts were selected (Table 2.1, Fig. 2.1).

2.2 CollectionofSecondaryData

Collection of secondary information is critical for the desired outcome of the study. Accordingly, relevant secondary data/information those are required to build-up ecological profile of coastal talukas was pre-identified through round of brain storming sessions (Table 2.2). The data were decided to organize, first into a simple database, and later be transported into GIS platform. For collecting the data which can easily be exported into GIS, detailed formats for each of the data sets were developed. Majority of data were collected from offices of various Government Departments and Agencies. During the course of this study, however, out of comprehensive list, data/information was able to collect only on certain parameters (Table 2.2)1.

2. APPROACH AND METHODOLOGY

1 It is important to mention here that taluka like Jalalpur was recently carved out from existing talukas of Valsad district. Therefore, most of the available government data are yet not been updated for the taluka.

Approach and Methodology

The data thus collected were tried to analyse for the trends over the years. For better

comprehension, the analysed data are presented in tabular forms and also depicted

through GIS maps.

2.3. CollectionofPrimaryDataonBiologicalParameters

It was well understood that while there are many information on various aspects of

environment that can be collected from various Government Departments and Agencies,

data on floral and faunal elements and their habitats at taluka level is almost non-

existent. Thus as part of this exercise it was decided to undertook rapid field surveys

to make inventories of key floral and faunal elements in each taluka. Based on round of

discussions with the team members, approach & methodology has been finalized.

In each taluka, field surveys were conducted to make an inventory of flora and fauna (the

birds, reptiles and mammals) and also recorded key habitats attributes. For this, sample

points were identified through a two stage process. Initially, the areas of ecological

importance (e.g. hills, forests, wetlands, river beds, reservoirs etc.) in each taluka

were marked on 1:50,000 scale topo-sheets. Later, in each of these identified areas,

sample points were located based on obvious variations in the vegetation, topography,

disturbances etc. The sample points were identified using field judgment of project team.

While in this method there was obvious risk of biasness in selecting sample points, but by

selecting more number of sample points, this biasness get nullified, to a certain extent.

Actually, the project team looked for different habitat conditions while moving from one

location to another and once observed any such visually different habitat was observed

it was sampled to account the floral and faunal diversity.

Circumstantially the entire study was done in two parts in different seasons wherein the

first part of the survey was carried out between 22nd November 2008 and 20th February

2009 in winter season. It is important to mention here that, while vegetation and habitat

inventories were covered in all the 12 talukas, the faunal inventories were possible only

in 9 talukas2. During initial part of the study a different approach of survey and primary

data collection was employed by using sample points for floral and faunal component. In

each sample point, a circular plot of 17.85 m radius (i.e. 0.1 ha size) were employed for

recording different parameters related with vegetation and habitats. While above plots

were used for search and record of reptilian species, for bird and mammals, the survey

was conducted beyond the plot and thus covered larger areas.

2 The faunal inventories were restricted mainly due to not finding suitable field researcher having experience in field based faunal inventories.

Approach and Methodology

During second season of sampling a slight modification in the approach was done. The field work was conducted between October 2009 and February 2010. Based on field experience and quality of recorded data on flora and fauna in the first round of field surveys (in 12 talukas), it was strongly felt that there is a need to adopt a scientifically rigorous approach for sampling and data recording for the second phase of the study. Thus, in order to do a systematic data collection on floral and faunal elements, sampling approach was modified and also adopted in the field. Thus during this phase, data were recorded for only winter season.

Thus, in order to make the sampling approach ecologically more representative of the ground reality, stratified random sampling approach was adopted. For this, printed copies of landuse/ land cover map (1:250000 scale) of each taluka was procured from BISAG (Bhaskaracharya Institute for Space Applicationa and Geoinformatics). Subsequently, on these landuse /landcover map (like forest, grasslands, scrub lands etc), grids of 1km x 1km size were overlaid. Total number of grids under each landuse/landcover category was enumerated and of each category, between 10-15% grids were randomly selected for sampling purpose. Furthermore, to ensure that the grids are distributed evenly, the entire taluka was also divided into three equal vertical zones and almost equal number of grids was selected from each of the zones (Fig. 2.1). In this approach, transect sampling was taken in consideration in faunal and floral sampling in selected talukas.

During entire studies, both direct and indirect evidences of wildlife were recorded. In each

plot, many habitat parameters (like topography, surface, vegetation cover, anthropogenic

pressure, etc.) were also recorded to derive some correlations with faunal and floral

elements. Wherever possible, photographic evidences were also collected for plant and

animal species.

Approach and Methodology

For collecting the information in the field, data formats had been prepared separately

for recording various habitat parameters and also different elements of plant and animal

species. A total of seven different formats were developed for the above purpose (See

Annexure 2.2).

The collected data were analysed for different ecological parameters like density,

frequency, species richness etc.

Overall, 1339 sample points were surveyed for making vegetation and habitat inventories,

only 447 points were surveyed for faunal records during entire study (Table 2.3). The

locations of all the sample points in different talukas were presented in Fig. 2.2.

3.1. HabitatCharacteristics

During the survey of both the phase, data were collected from 1339 sample plots of 447 transects were taken. These plots represent different types of habitats in different proportions. A total of 15 different habitat types were sampled during the entire survey (Table 3.1). Riverine Open and Dense Scrubs and Shrub Savannas were the most frequently sampled types. A total of 19 mangrove sites were also surveyed along with 107 other sites representing aquatic bodies as well as salt pans. Furthermore, these sites were also sampled from different terrain types. Being the coastal talukas, majority of the sample sites were found in flatter terrain followed by undulating and hilly areas.

Flora-Fauna Status

During the field survey, at every sample point, information was collected on different parameters of habitat and anthropogenic pressures. For this, the conditions were evaluated occularly and given a score between 0 and 5. A total of 1333 sample points were surveyed during the study. A pie chart represents the overall habitat types coveredduring the surveys and sampling suggesting open scrub, agriculture and riverine to be the majorly surved sites (Fig. 3.1). For better comprehension about each of these habitats and anthropogenic pressures, the average value of given score for all the sample plots in each Taluka was presented (Table 3.2, Fig. 3.2). Thus, it is quite clear that among the talukas, Valsad had best tree canopy cover followed by Khambhat and Gandevi talukas. However, grass and herbaceous cover was found best in Bhavnagar followed by Mahuva, Ghogha, Hansot and Valsad talukas. In anthropogenic pressure terms, the Mahuva taluka had highest number of cattle dung pats, suggesting high degree of grazing pressure.

Flora-Fauna Status

In fl oristi c terms, with the record of 231 and 221 species, the Una and Mahuva are the two

richest talukas, respecti vely followed by Rajula (190 sp.) and Kodinar (184 sp.) (Fig. 3.3).

It is generally observed that the record of species is determined mainly by the sampling

eff orts. However, to negate this eff ect, average number of species encountered in unit

sampling eff ort was measured. Thus Umbergaon recorded 160 species in just 16 sample

points i.e. an average of 10 species per sample point (Table 3.3). On the contrary, from 42

sample points in Ghogha, 137 species were recorded with an average of 3.26 species per

sample point. In above context, therefore, talukas like Umbergaon, Bhavnagar, Vagra and

Hansot are supporti ng rich fl oral diversity, while in comparison, the talukas like Ghogha,

Talaja, and Dhandhuka are poor in species diversity.

Fig. 3.3. Shows diversity of fl oral species in diff erent talukas

studied in both seasons.

Other factors, which could infl uence the fl oral species diversity, include the

geo-morphological diversity and rainfall regime. However, due to inadequate informati on,

the relati onships could not be established further.

Overall 430 fl oral species were recorded from 19 talukas. From obtained record

of species, 145 species were woody in nature, 236 species were herbaceous and

49 species were climbers.

3.2.2 Species Abundance

For the purpose of recording the abundance of different plant species in different

talukas, the density of each species was measured, initially for each sample point and

subsequently extrapolated for the entire taluka. However, the same was used only for

the woody plant species (i.e. trees and shrubs). It is important to state here that being

the coastal talukas, the sampling efforts was also made in the coastal mudflats (including

the patches of mangrove). The result is, therefore, presented separately for terrestrial

areas and coastal mudflat areas.

A total of 19 sample plots were surveyed in coastal mudflat areas. The coastal mudflat

areas are predominantly covered by Avicennia marina (a mangrove species). Rhizophora

mucronata, another mangrove species was also found in Umargaon and Jalalpor talukas.

A few other terrestrial species also associated with these species on fringe, drier and

higher areas of the mudflats. In terms of density of total plants (mature as well as the

saplings) of these species, A. marina had higher density of plants (Table 3.4).

Flora-Fauna Status

In the terrestrial areas, the woody plant density varies a lot across the talukas. Thus, while

talukas like Valsad and Vagra had the highest density of plants, the Rajula, Kodinar and

Jafrabad recorded lowest density of woody plants (Table 3.5, Fig. 3.4). Importantly, within

the sampling areas, only four species viz. Acacia niloti ca, Azadirachta indica, Prosopis

julifl ora and Zizyphus jujuba were recorded from all the talukas. Cassia auriculata,

Calotropis procera, Capparis sepiaria, Derris indica and Salvadora oleoides were the

other commonly recorded species. In terms of density of plants, values varied greatly

for diff erent species across the talukas. Needless to say, Prosopis julifl ora was found with

average maximum density followed by Acacia niloti ca and Bambusa bambos (Table 3.5).

Prosopis Julifl ora, is one of the important invasive species belonging to family

Fabaceae and subfamily Mimosoideae. An invasion of this species is now

expanding in its area in desert and semi desert, arid ecosystems. Gujarat being

one of the coastal states, the species has its strong foothold in coastal areas and

is conti nuously expanding. Present study showed Prosopis Julifora as one of the

dominant species in terms of density (5160.28 No./ha) in all surveyed talukas.

The plant and its pods are one of the important food for the livestock and the

wild ungulate and other herbevores. The main reason for its fast invasion is

att ributed to the role of livestock, people and wildlife in dispersal of seed.

MangrovesofGujaratCoast

Mangroves: One of the most important plant communities situated throughout the

coastal region. They are found only in the tropical and subtropical regions. Mangroves

are trees or shrubs, often clustered together. Trees can grow to a height of 25 metres.

Large groups of mangroves and other plants found here are called mangrove swamps,

mangrove forests or mangals.

Mangrove forests are among the most productive ecosystems on land. They are natural

marvels not only due to their adaptations, but also for the important role they play in our

environment. In India, there are 34 species of true mangroves. Bhitarkanika (Orissa) has

31 species, the Sundarbans have 27 and the Andaman & Nicobar islands have 24 species

of mangroves. As compared to the above mentioned status, in Gujarat, total 14 species

of mangroves have been recorded. Total 12 species are recorded from 19 talukas of the

Gulf of Khambhat during the field survey and other secondary data source.

Threatstomangroves:

The increasing human population is exerting tremendous stress on the mangroves, with

land reclamations and discharge of waste causing their degradation.

Shrimp farming is a major reason for t\he destruction of mangroves. These forests are

the natural habitat of shrimps. Large areas of mangroves are cleared to create artificial

ponds for shrimps. This has also led to the loss of habitat for other fish.

Rising temperature and rising seas: Rising sea levels due to climate change and the

consequent rising temperatures pose a grave threat to mangroves. Large areas of coastal

mangroves could be lost if sea levels continue to rise due to the expansions of the oceans

and melting of polar ice caps

Development activities:Developmental activities near coastal area are also a major

threat to mangroves. Building of ports and jetties is another reason for cutting down

mangroves.

Flora-Fauna Status

3.3. FaunalCharacteristics

As discussed earlier, efforts were being made to make inventories of three major groups

of fauna: the mammals, birds and reptiles. Due to logistic and manpower related issues,

the faunal inventory work was covered in two different parts whereinin first phase only

in nine talukas were covered and therefore few of the same is proposed to be repeated in

the second part of the study3. Nevertheless, later year’s sampling efforts indicated some

interesting aspects of species diversity and their distribution.

3.3.1. Mammals

Overall, 28 mammalian species were found from 19 surveyed talukas during entire study

covering attempts of both the seasons. During the survey, presence of a total of 10

mammalian species was recorded from 32 sample locations of five talukas (out of total

71 surveyed locations in nine talukas). Obviously, the sampling effort is not adequate to

derive some measures of diversity and abundance. Out of 32 sample sites covered, 22

were from Talaja and needless to say 9 out of 10 species were recorded from this taluka

(Table 3.7). In terms of species richness, Una (19 sp.) and Bhavnagar (18 sp.) showed

maximum richness followed by khambhat, Mahuva and Rajula (Fig. 3.5). Looking logically

to the mammalian species encounter rate, Bhavnagar and Khambhat represented

highest values of 0.55 while the same for Ghogha, Chorasi and Vagra can be suppressed

considering the less number of transects for the talukas compared to other talukas

(Table 3.7).

The braod context of presence and absence of different mammalian species in studied

talukas can be represented in Table 3.8. Further, Table 3.9 shows the frequency record

of different species in different talukas by local people during the interaction with local

public on field. Five stripped squirrel was the most commonly encountered species

directly during the field surveys in different talukas followed by Bluebull (Table. 3.10).

Moreover, Khambhat and Bhavnagar showed high rate of frequency of mammals as on

indirect records as represented in Table 3.11.

3 It is important to understand that inventory of bird, mammal, reptile and amphibian species is a specialist’s job. Therefore, to find out a single field researcher with sufficient experience and expertise on all above taxa is very difficult task. Project, however, did not get a any good student for the job for quite a long part of the project. This sufficiently delayed the field work. Therefore, compared to the plants, the total numbers of talukas covered for faunal inventory are less. Also, a total of 71 sample points were surveyed for faunal species records. Clearly, this is not adequate to record the faunal species diversity. Thus it needs to substantiate in the next phase of the study.

NILGAI (Boselaphus tragocamelus)

During the entire Phase of study, it was observed that blue bulls (Boselaphus tragocamelus)

were frequent in most of the talukas. Moreover, during the surveys, most of the local

people especially the farmers complained about the nuisance and crop raiding by the

Nilgai and problem of their increasing population. Above image shows a standing crop

being raided by the herd of Bluebulls.

InterestingFacts:

• Nilgai is a sturdy species which is represented by a stocky body. The distribution

of the Nilgai was mainly to the peninsular India which is expanding day by day.

The species is well adapted to diverse habitat conditions and thus successfully

expanding their distribution in the state as well as country.

• The Nilgai is mainly diurnal, with peaks in activity in the early morning and late

afternoon. The sense of sight is well developed among this wary species. When

chased, Nilgai can run up to 48 kmph / 29 mph. Being territorial, the species many a

times marks its territory by their dumping their excretory pellets at particular place.

• The current population of Nilgai in the state is 1 lakh, of which 10,000 are located

in 90 villages in Ahmedabad and 30 villages in Gandhinagar. The existing population

of Nilgai has been one of the issues for State’s farmers. The herds of Bluebulls have

been raiding the standing crops of the farmers causing them a great damage to

their yield in one night itself. Even the fencing and electrifying the farm boundary

has failed against the invasion of this feral and sturdy animal. The Gujarat state

government decided to give licences to the Sarpanchs after the terror of Bluebulls

reached menacing proportions.

Flora-Fauna Status

Some of the interesti ng and ground level facts came forward during the fi eld surveys

and interacti ons with the local public. Interacti on with local people revealed interesti ng

informati on about the past status of the animals in the area and the present scenario as

per their view being in direct touch with the habitat. Bluebull has covered most of the

area in Gujarat and increasing in populati on taking benefi t of their adapti veness. In most

of the surveys, local people (especially farmers) complained about the nuisance of the

animal being damaging their standing crops.

Secondly, important sighti ng of Asiati c lions in few of the talukas suggests range extension

and dispersal of Asiati c lions beyond Gir Nati onal Park and Sanctuary. The same in brief

IDENTIFIED THREATS TO THE FAUNA

Industrial developments coupled with infrastructure development with anthropogenic

activities have been indirectly creating negative impacts on the adjacent biodiversity.

Though inevitable, there is pressing serious need to conserve the biota along with

development to make them go hand in hand. During the visit, few of the serious

anthropogenic effects were seen on the fauna.

Mining – Mining has been a serious issue which was seen in certain talukas. The mining

directly alters the prevailing habitat and results in different type of pollutions like air,

noise and particulate matter pollution. The habitat destructions results in direct loss or

migration of the faunal group. Moreover, resultant transportation activity and the human

interventions disturb the existing natural ecosystem as well as the animal movement.

Increasing traffic/ road network: Road network has been one of the important components

of development. The increasing road network has consequently fragmented the natural

habitats at macro and micro level. For e.g. even the bisecting of agriculture fields by

roads has been disturbing the living biota due to disturbance.

Road accidents during the transit of animals have been a serious issue. Many cases of

road accidents were reported during the study which includes mammalian, reptilian and

amphibian accidents.

Asiaticlion(Panthera leo persica)

Interestingly, Asiatic lion has been reported in six talukas (Bhavnagar, Jafrabad, Kodinar,

Mahuva, Rajula and Una) during the surveys (based on both direct and indirect evidences).

This evidences the increasing population of Asiatic lion and their spread beyond their

previous home range.

UpdatesofAsiaticlion(Panthera leo persica)populationinrecentpast:

The table shows the population status from 1963 to the year 2010. The constant increase

in the lion population with a steep linen from 177 to 411 lions in the year 2010 evidences

the very good health of the ecosystem.

3.3.2. Birds

Overall, 215 bird species were recorded from 19 talukas surveyed. During the survey, a total of 157 bird species were recorded in 71 sample locations across 9 talukas. A checklist of bird species recorded during the survey is presented in Annexure 3.2. In terms of bird species diversity, with the record of 145 and 144 species, the Rajula and Jafrabad are the two richest talukas, respectively (Fig. 3.6). However, the sampling effort varies across talukas and to remove the effect of this, average number of species encountered in per unit sampling effort was also measured. Thus, Jalalpor recorded 83 species in just four sample points i.e. an average of 20.8 species per sample point (Table 3.12). On the contrary, from 26 sample points in Talaja, 125 species were recorded with an average of 4.8 species per sample point. In above context, therefore, talukas like Jalalpor, Umergaon, Ghogha and Olpad, are supporting relatively rich bird diversity. During second season of the study, Kodinar and Bhavnagar showed highest species encounter rate (Table 3.12). Fig. 3.6. shows the graphical presentation of number of

avian species recorded from different talukas during the surveys.

GLIMPSE TO AVIFAUNAL STATUS

Overall 215 bird species were recorded from 19 talukas surveyed during Phase I and II respecti vely. Rajula and Jafrabad talukas emerged as the richest talukas in terms of avifauna. In terms of migratory birds, Khambhat and Bhavnagar showed good congregati on of waders in shallow coastal waters and saltpans respecti vely.

Moreover, a good diversity of larks was evident in Bhavnagar talukas and the Bhal area. Most of the ti me eff ort was made to survey the birds in early morning and in migratory season.

In terms of frequency of record of species in each taluka, it was found that, only two

species, the Green Bee-eater and Rock pigeon were recorded from all the nine talukas.

On the contrary, there were 49 species which were recorded only in one or two talukas.

The frequency of record of species in each sample locati on suggested that only three

species viz Black Drongo, Green Bee-eater and Red Vented Bulbul, were found in more

than 50% of total sample points (Table 13). On the other hand, 116 species were recorded

from less than 5% of the total sample points.

Although population count was not attempted systematically during the survey, based

on direct sightings, the number of individuals of each species in each sample point was

recorded and later grouped into four population classes. The population class wise

record of species in each Taluka is presented in Annexure 3.2. Obviously, more number of

species was recorded in small population, yet in taluka like Talaja and Umergaon, Vagra

and Ghogha, many species were recorded in large population (Table 3.14).

ImportantsightingsofGypsVulturesFew of the rare sightings of vultures were there during the study period which can be the

update to the state’s vulture inventory. An important sighting of 09 Indian white rumped

vultures (Gyps bengalensis) and 03 Long billed vultures (Gyps indicus) was seen by the

study team on 08/10/2010 in Nagra village of Khambhat Taluka. The birds were seen

resting on the Borassus flabellife.

STATUS:The Indian Vulture (Gyps indicus) and the Indian White-rumped Vulture, G. bengalensis

species have suffered a 97% - 99% population decrease in Pakistan and India.

Flora-Fauna Status

Both the species have been placed under critically threatened category by IUCN.

The cause of this has been identified as poisoning caused by the veterinary drug

diclofenac.

3.3.3. Reptiles

In total, 32 reptilian species were found in from overall studied talukas. During the

survey, record of reptilian species was quite restricted mainly due to the winter period of

sampling in most of the talukas. Out of total 447 transects taken in entire study period,

only 143 transects marked presence of reptiles proving the lower encounter scenario

(32%) of reptiles as compared to mammals and birds. Nevertheless, a good record of

reptilian sighting was seen in Khambhat, Bhavanagar and Rajula talukas with high

number of reptiles species as well as good successful transect ratio (Table 3.15). Further

Fig. 3.16 represents the recorded number of different reptilian species from different

talukas wherein common garden lizard is the highest reported species while common

Indian monitor lizard showed its presence in every taluka.

REPTILIAN HIGHLIGHTS

In total, 32 repti lian species were found in total studied talukas during both

studies. Bhavnagar and Khambhat showed highest records of species during

the surveys. But the repti les are diffi cult to sight and are very rare to be recorded

in a short ti me frame of the visit.

During the survey, record of repti lian species was quite restricted mainly due

to the winter period of sampling in most of the talukas. The sighti ng of Indian

monitor lizard Varanus bengalensis was frequent during the road transits

suggesti ng their vulnerability to road traffi c.

Extensive eff orts were made to record the repti lian diversity of the study

areas using the available direct and indirect evidences. In salt pan area around

Velavadar of Bhavnagar Taluka, cases of snake bites specially by Russel’s viper

and Saw scaled viper were frequently heard from the local public.

Socio-Ecological Trend

4.1. Climate

Rainfall is the most important climatic factor that influences the ecology and thus economics of the region. During this study, average annual rainfall data between 1980 and 2002 was collated for all the 19 talukas4. The data suggest that comparatively while Valsad, Umbergaon, Gandevi and Chorasi talukas recorded higher average annual rainfall, the Vagra, Talaja, Mahuva, Ghogha, Rajula talukas recorded lower rainfall (Table 4.1, Fig. 4.1)5. As far as recent trend is concerned, it is recorded that while comparing the average annual rainfall in the decade of 1980-1990 & 1991-2002, there was decline in the average annual rainfall in 10 talukas.

4.2. HumanPopulation

The human population growth indicates the trends in resource availability. In other words,

it suggests the pressure on the existing natural resources, e.g. change in per capita forest

availability. On overall basis, almost all talukas recorded an increase in the population

(Table 4.2). A few talukas, on the other hand, recorded a decline in their population. This

is just a discrepancy in the census figure mainly due to reorganization of some talukas and

to create a few new talukas (like Jalalpore). The table also presented BPL population in

each taluka. Valsad and Umbergaon talukas recorded highest percentage of BPL families

(Fig. 4.3 and 4.4). The high proportion of BPL families also indicate higher degree of

dependence on common natural resources like forests, pasturelands etc. In above two

terms (total population and BPL population), the influence of human population on local

ecology can be indicated. The population of socio-economically marginalized groups like

SC & ST is correlated with BPL families.

4.3. Landuse

Land use is based on the functional dimension of land for different human purposes or

economic activities. Thus, in a sense, the land use system of any given area is significantly

controlled by its ecology. In the present context, some of the categories of land use

which have strong ecological connotation include the forests, barren areas, pasture land,

culturable wasteland, fallow, and agriculture lands. The data about area under different

land use categories at every five year interval are collated from Revenue Department.

The data were collated from 1980-81 to 2004-05 and were analysed for the overall

change between 1980-81 and 2004-05. Following are the key indications derived from

these data sets:

(i) Forest: In general, the forest area gets declined in quite a many talukas (Table

4.3a). The maximum decline in forest area was recorded in Una taluka of Junagadh

district, where between 1980-81 and 2004-05 more than 33000 ha forest land was

converted into any other landuse. Similarly, in Jafrabad taluka of Amreli district also

recorded a decline of about 2200 ha forest lands. On the other hand, taluka like

Dhandhuka in Ahmedabad district recorded an increase of about 2600 ha in forest

area. However, due to insufficient knowledge about the causes of such decline and

increase in forest land, it is difficult to comment on these.

(ii) Barren: In cumulative terms, in the 19 talukas, the area under barren category gets

increased. However, this is mainly due to increase of about 31300 ha and 4800 ha

in barren area in two talukas viz. Una in Junagadh district and Jambusar in Bharuch

district, respectively (Table 4.3a). Contrary to this, there was a decline of about

19500 ha in Dhandhuka taluka in Ahmedabad district. Reasons for such large scale

shift need to be explored.

(iii) Pasture Land: On overall basis, the area under pasture lands declined in the 19

talukas along the Gulf of Khambhat. However, it is important to mention here

that between 1980-81 and 2004-05, in 9 talukas, there was no change in the area

designated under pasture lands. Dhandhuka and Rajula talukas, on the other hand,

recorded a decline of about 3250 ha and 1200 ha in their pasture lands, respectively

(Table 4.3a).

(iv) Culturable Waste: During the period of 1980-81 and 2004-05, the area under

culturable waste showed different trends across the talukas. Thus, for example,

while in Khambhat and Vagra talukas the area under culturable waste has increased,

the same was recorded to decline in Dhandhuka, Bhavnagar and Chorasi talukas

(Table 4.3b).

Socio-Ecological Trend

(v) Fallow: In the land use statistics, data on fallow lands is recorded in two major

categories- the current fallow and other fallow. For present purpose, the two were

summed-up and presented as total fallow. While, cumulatively, there is a decline in

the area under fallow category in 19 talukas, individually talukas behaved differently.

Thus, talukas like Rajula, Mahuva and Jambusar showed an increase in the fallow

lands, the same showed declining trend in Chorasi, Olpad, Valsad, Kodinar and

Bhavnagar talukas (Table 4.3b). The shift in area under fallow land could significantly

influence the economics as well as ecology of the area. However, it requires further

field level probing to derive better understanding of the same.

(vi) NetSownArea: The net sown area indicate the actual land area under cultivation

and thus not account for multiple crops from a single parcel of land. Effectively,

adding of this and fallow lands, actually provide the total extent of cultivable land.

During the period of 1980-81 and 2004-05, the trend in net sown area differs

across the talukas. Thus, while Dhandhuka recorded the highest decline (~73200

ha), talukas like Khambhat, Rajula & Mahuva also recorded a decline. Contrary to

above, in talukas like Bhavnagar, Kodinar, Valsad etc. the same was found increased

(Table 4.3b, Fig. 4.5). The causes for the increase in net sown area generally linked

to improved irrigation facilities, which on the other hand had many associated

ecological consequences. Only through some in-depth studies, proper assessment

can be made.

Socio-Ecological Trend

4.3.1. Forest

Forest area is one of the positive indicators of health of environment of a region. Thus

information was collected on the extent of different categories of forests in each taluka.

The data was available for the period between 2000 and 2009. However, the values were

found to be same for all the years for all the categories. Thus, in the present context, no

trends were analysed. Nevertheless, it is recorded that out of 19 coastal talukas along

the Gulf of Khambhat, four talukas (viz. Khambhat, Jambusar, Chorasi and Olpad) do not

possess any forest area. On the contrary, Dhandhuka, Vagra, Umbargaon and Jalalpore

talukas support more than 3000 ha area under forest categories (Table 4.4). Importantly,

five talukas also possess vidis (grasslands) under reserved or non-reserved categories. The

talukas do not consist of any wildlife Protected Areas (viz. National Park and Sanctuaries).

Socio-Ecological Trend

4.4. AgricultureandIrrigation

The data on cropping pattern and area under irrigation by different sources have been

collected for the period between 1990-91 and 2004-05. Area under four major crop

groups viz. Cereals, pulses, oilseeds & cash crops, were analysed to record their trends at

taluka level.

Accordingly, 13 talukas recorded a decline in the average area under cereal crops

between periods of 15 years (i.e. 1990-91 to 2004-05). Maximum decline was recorded

in Bhavnagar (69%), Mahuva (66%) and Dhandhuka (51%) talukas. On the contrary, Olpad

and Kodinar talukas recorded an increase of more than 30% in the area under cereal

crops (Table 4.5) In case of pulses, however, while 10 talukas recorded a declining trend,

other eight talukas recoded increase in the area of pulse crops. Hansot, Valsad and Vagra

recorded maximum decline in pulse crop area, while in Kodinar, Bhavnagar, Jafrabad and

Umergaon the area under pulse cultivation was increased by more than 100% (Table 4.5).

Similarly, the trend in area under oilseed crops varies across talukas. Thus, while on one

side 10 talukas recorded a decline in its cultivation (e.g. Khambhat, Valsad, Hansot, and

Dhandhuka), the remaining seven talukas recorded an increase in their cultivation (e.g.

Una, Gandevi, Bhavnagar). Interestingly, while there was an overall decline in area under

cereal, pulses and oilseed crops, the cash crops (that include Cotton, tobacco, sugarcane

etc) recorded an increasing trend in almost all the talukas (except in Dhandhuka). Jafrabad,

Gogha, Olpad, Mahuva and Hansot talukas recorded a high percentage increase in cash

crop area (Table 4.5). Cummulatively, change in area under different crops is presented in

Table 4.6. Accordingly, except cash crops, all the crops showed a declining trend in the 19

talukas along the Gulf of Khambhat.

Socio-Ecological Trend

The data were also analysed for trends in specific crops under each group separately for

each taluka (Table 4.7a & 4.7b). Thus, while area under paddy was increased in Chorasi and

Hansot talukas, Una recorded an increase in area under wheat by about 20%. Interestingly,

the Bajri crop was found increased in all the four coastal talukas of Bhavnagar District

(Table 4.7a). Pulse crop like Math was found increased in Jafrabad and Rajula talukas of

Amreli district and Ghogha and Talaja taluka of Bhavnagar district. The decline in Val was

prominent in Umargaon and Valsad talukas of Valsad district. Similarly, cropping pattern

for oilseeds and cash crop varies across the talukas (Table 4.7b).

Fig. 4.7. represents the percentage change in crop production in consequrtive years while

the Fig. 4.8 a, band c shows the different type of crop production observed in 1991- 2004.

Though no proper trend was seen in the cropping pattern.

Socio-Ecological Trend

The data on irrigation resources suggest three major sources viz. tank (surface water),

canal and dug well (ground water). In case of 19 talukas, ground water is the main source

of irrigation, followed by canals. Tanks, on the other hand, contribute very small proportion

of total irrigation. On overall basis, the total area under irrigation shows increase over the

years (Table 4.8), but the growth of irrigation sources varies across talukas (Table 4.8).

Thus, the tank irrigation shows decline in many of the talukas, the irrigation by dug-wells

(i.e. from ground water) has increased in many talukas (Table 4.9). For example, ground

water irrigated area in Vagra taluka of Bharuch district has increased from a meagre 17 ha

in 1990-1995 to 1182 ha during 2001-05.

The ecological consequences (like salinity ingression) of increasing exploitation of ground

water in coastal talukas need to be correlated with the dynamics and management of

irrigation systems. Also, the irrigation data needs integration with the socio-economic

parameters and policy issues for better comprehension about the driving forces for changes

in irrigation system. Lack of such data, however, limits the ecological interpretation.

4.5. Livestock

The livestock population data was available from two livestock census- 1997 and 2003.

Taluka wise population of major livestock like cattle, buffalo, sheep, goat and camel in

2003 is presented in Fig. 4.14, 4.15 and 4.16. On overall basis, between 1997 and 2003,

there was an increase of about 6.4% and 9.4% in total population of cattle and buffalo,

respectively. However, in Jafrabad, Rajula and Gandevi talukas, there was a decline in the

population of both cattle and buffalo (Table 4.10). On the contrary, Choriasi, Dhandhuka,

Olpad, Jalalpor and Bhavnagar talukas recorded an increase in both cattle and buffalo

population. The population of Goat was also increased over the years.

Socio-Ecological Trend

4.6. Energy

Environmental changes are results of the dynamic inter play of socio-economic, institutional and technological activities. Other than population growth, urbanization, intensification of agriculture etc. one important driver of environmental degradation includes the rising energy use for economic growth and transportation. Actually, lack of access to clean, affordable energy and over use of fossil energy adversely affects both, the poor and the environment. So much so, the issues of global climate change are directly linked to disproportionate use of fossil energy.

Thus, in the context of this study, efforts have also been made to understand the recent trends in energy use. It is important to mention here that the analysis is not aimed to bring direct correlations between the use of different energy types and environmental degradation in coastal talukas. But at the same time, it gives recent trends in two energy parameters:(i) Electricity consumption by different sectors(ii) Fuel consumption

4.6.1. ElectricityConsumption

The electric consumption data of 2000 to 2009 was collected from electricity supply companies. In terms of electricity consumption between 2000 and 2009, the 19 coastal talukas along the Gulf of Khambhat showed widely varied values (Table 4.11). Thus, while Chorasi taluka in Surat district consumes on an average 1705 MUS, the Hansot taluka in neighboring Bharuch district used only 0.49 MUS electricity. (Fig. 4.13)

Between 2000 and 2009, as expected, the total consumption of electricity had increased across all the sectors for all the talukas (Table 4.12). However, in terms of share of electricity consumption by different sectors, data recorded interesting trends. Accordingly, in all the talukas share of electricity consumption in agriculture sector had increased by smaller proportions (Table 4.13 and 4.14). Interestingly, the share of electricity consumption in industrial sectors had recorded declining trends in all the talukas. It is however, very difficult to argue and interpret any environmental as well as economical consequences due to such shift in electricity consumption pattern.

4.6.2. FuelConsumption

The type and quantity of fuel used had serious implications on environmental health

because use of fossil fuels in higher proportions as main source of energy actually

contributes to air pollution. This section therefore attempts to present an analysis of

pattern of fuel consumption at taluka levels. The data are presented in following three

major sections

a. Sector wise fuel consumption for different fuel types

b. Recent growth in supplying domestic cooking gas through pipelines

c. Promotion of biogas plants

4.6.2.1.FuelUsePattern

The data on use and consumption of different fuel types in different sectors were collected

from respective Mamlatdar office. Accordingly, fuel use data for the period between 2000

and 2009 were collated for different sectors like transportation, industry, agriculture and

domestic.In transportation sector, information was found on the consumption of Petrol,

HSD and LPG/CNG. As expected, the data clearly suggest that in almost all the talukas,

fuel use for transportation purpose had increased.The maximum consumption of Petrol

and Diesel was recorded in Olpad taluka followed by Chorasi taluka (Table 4.15, Fig. 4.14).

Interestingly, Chorasi taluka also had maximum consumption of electricity units. The

LPG/CNG use is restricted only in Dhandhuka taluka and that too only for year 2008 and

2009. However, data suggest that the consumption had increased from 104574 kilolitre

in 2008 to 300354 kilolitre in 2009.

Socio-Ecological Trend

In Industrial sector, two major fuels are used viz. Superior Kerosene Oil (SKO) and Naptha.

The data is available only for four talukas. While the SKO use is reported from Mahua,

Jalalpore and Gandevi talukas, the use of Naptha as industrial fuel is reported only from

Chorasi taluka. Interestingly, at taluka level, the consumption of industrial fuels had

shown a steady declining trend between 2000 and 2009 (Table 4.16, Fig. 4.15b).

In domestic sector, data on consumption and use of SKO and LPG are collected for the

period of 2000 to 2009. Also, the available data is limited to only 11 talukas (for eight

talukas there was no data available). Accordingly, it is quite apparent that over the

years consumption of SKO had shown steady decline in most of the talukas (Fig. 4.2).

In contrast, consumption of LPG had shown sharp increase in majority of talukas (Table

4.17, Fig. 4.15a). This trend is expected to have serious positive health implications due

to reduction in indoor air pollution.

In agriculture sector, use of HSD and Crude Oil are reported. However, consumption data

of these fuels are not available for most of the talukas. Therefore, in this report, their

analysis was deliberately omitted.

4.6.2.2. Gas Pipeline

State is taking steps to provide domestic cooking gas to the doorstep of the households.

For this cooking gas are supplied through pipelines. Although, its exact environmental

consequences may not be direct and significant, yet in terms of efficiency in domestic

energy use, it had proven roles. Considering the enormity of the task, however,

laying down of pipelines and through that distributing the gas connection is currently

limited to only selected cities and towns. Many of the talukas have yet not been covered

under this plan. Contextually, out of 19 coastal talukas along the Gulf of Khambhat,

till 2009-2010, only six talukas are covered under this plan of supplying gas through

pipelines (Table 4.18).

It is important to mention here that in many other talukas the work of laying down of

pipelines and supply of gas is contracted to different private agencies (like Adani Gas).

Once the data from these private agencies are available, the picture will be clearer.

4.6.2.3. Biogas

The biogas is one of the non-conventional, renewable energy sources. Thus, its promotion

by various Govt. and non-govt. agencies is considered as environment friendly practice.

In 19 coastal talukas along Gulf of Khambhat, the biogas plants were promoted by Gujarat

Energy Development Agency (GEDA). The 10 year data between 1998 and 2007 suggests

that in the second half of this period the biogas plants were promoted more vigorously

compared to the first part of the decade. Still, however, in talukas like Hansot, Jambusar,

Chorasi, Umargaon, Vagra and Olpad, biogas plants have not reached to the masses. On

the other hand, in Valsad, Mahuva and Una talukas, number of biogas plants is quite high

4.7. Industry

The purpose of industrial development is to provide opportunities of better living and employment to the people. While industrial development almost inevitably creates more employment in the region, the possibilities of adverse effects on the environment also increased if these adverse effects are not properly contained or reduced to minimum. Gujarat’s coastal tracts are providing suitable conditions for setting-up of industries and thus are prone to environmental degradation.

For the present study purpose, data on growth of medium and large industries in 19 talukas were collected for the period between 1986 and 2010 (total 25 years). The data expectedly highlight that there is a continuous growth in setting up of both medium and large scale industries in most of the talukas. Particluarly, the medium scale industries were more rapidly installed in Umargaon, Valsad, and Chorasi talukas. The large scale industries, on the other hand were promoted in Chorasi and Vagra talukas (Table 4.20, Fig. 4.16).

Socio-Ecological Trend

In addition to above, at larger scale industries like ship-breaking in Alang-Sosiya area

of Ghogha taluka of Bhavnagar district had several serious environmental issues,

mainly associated with pollution. Similarly, in talukas like Olpad, Chorasi , Vagra etc. the

uncontrolled industrial development had been a major concern. Industrial clusters like

Hazira near Surat city had also raised several environmental issues. Although, this study

did not attempt to go into the details of such industrial clusters, it is important to take-up

such industrial clusters as case studies to record various environmental issues, specific

to that region.

4.8. RoadNetwork

Road network development enhances mobility and is critical for economic growth of

a region. However, inappropriately planned, designed and constructed road networks

can aggravate the conditions of the poor people, and could harm the natural and socio-

economic environment. Some of the common impacts of ill planned road network

include damage and fragmentation of habitats for wildlife, change in hydrological regime,

wetland shrinkage, pollution, etc.

In the present context of 19 coastal talukas, the data on development of different types

of road network was collected for the period between 2000 and 2009. The last ten years

data suggest that there is continuous growth in the development of road network in all

the talukas (Table 4.12). However, it is very difficult to record various impacts of these

road networks on the ecology of the surrounding areas.

4.9. FishProduction

The fish production is considered as both, the indicator of alteration in the coastal

environment and also the cause of changes in marine ecology. Thus, while decline in

fish production, on one hand suggests that there is some problem in coastal and marine

environment (e.g. increased pollution load), on the other hand, this could be due to

unsustainable / overfishing or even due to issues that involve the impact of fishing on

the environment, such as dumping of by-catch. Thus, a time series fish production data

may indicate the overall health of fishery environment.

In the context of present study, in the 19 talukas, fish production data of 58 fish landing

centres were collected for the period between 1998-99 and 2008-09. The average annual

fish production during this 10 year period indicates that 29 landing centres had catch of

more than 1000 tons, 22 landing centres had upto 500 tons fish production and remaining

7 centres had between 500 and 1000 tons fish production. Jafrabad and Shiyalbet in

Jafrabad taluka and Rajpara and Nava Bandar in Una taluka recorded higher average fish

production (Table 4.22, Fig. 4.18). Further analysis of this data suggest that in 21 out

of 58 landing centres, the fish production recorded declining trends. Sites like Bilimora,

Dandi Maroli, Katpar, Vagrech and Daheri showed more than 50% decline in fish catch.

annual fish catch of more than 10000 tons, while Hansot, Vagra, Bhavnagar, Mahuva

and Talaja recorded less than 1000 tons average fish catch (Table 4.23). Four talukas viz.

Bhavnagar,Valsad, Kodinar and Chorasi recorded a decline in their fish production. The

actual causes of such decline need to be explored further.

Socio-Ecological Trend

4.10. Salt Work

Other than fisheries, salt manufacturing is one of the major industries that use the

coastal and marine resources. While the salt work is a major source of livelihood for

large number of people (agarias), increasing mechanization has improved production

efficiency. Nevertheless, the entire sector has many direct or indirect environmental

concerns and thus, considered as critical sector for coastal ecology. Thus, in the present

context, data on the growth of this sector in 19 coastal talukas were collected for the

period between 1991 and 2009.

Importantly, only in 12 talukas salt works were found operating. Except in Vagra taluka,

in most of the other talukas the scale of salt work operation were found relatively to be

at lower level. Nevertheless, it was found that between 2000 and 2009,the area under

salt work had increased in most of the talukas (Table 4.24). It is important that in order

to ascertain the impact of these salt works on ecology and environment of these coastal

talukas, detailed study need to be commissioned.

Conclusion

Gulf of Khambhat is considered as one of the important natural systems of the Gujarat state. In administrative terms, the Gulf is bordered by 19 talukas belonging to 9 districts. Last census (2001) suggests that about 4.73 lakh people live in these 19 talukas. Due to its geographical positioning, physical and oceanographic characteristics, and large human population around, the gulf is vulnerable to various anthropogenic activities including rapid industrialization and coastal infrastructure development projects (like ports, oil terminals etc.), jeopardizing both ecological as well as livelihood securities along these regions.

Realizing that for the effective planning and management of various natural resources and key ecological systems in and along the Gulf of Khambhat, it is important to understand the trends of various drivers (climatic and anthropogenic) and response variables including the state of floral and faunal species. Keeping above in view, this study is the first attempt towards creating an ecological profile by collecting and organizing ecological information of the coastal talukas along the Gulf of Khambhat, and, to understand their trends at taluka level.

The study suggested that despite many limitations in secondary data (in terms of their consistency and periodicity) some basic analysis of those data actually help in recording some interesting trends, although not conclusive. The trends and their interpretation, mainly through multiple correlations and regression, of different parameters would vastly improve by collecting robust time series data for each of the parameters.

The study has demonstrated interesting spatio-temporal changes and trends in various land use categories, cropping and irrigation patterns, energy uses etc., but the data needs further exploration. Similarly, more intensive and systematic ecological surveys need to be considered for better understanding of abundance and distribution of key floral and faunal species, especially the rare and endangered ones.

It is also important to mention here that while attempts are made to present the trend of different parameters independently, many of them may have significant correlations and regressions and thus influencing and explaining the values of each others. However, these multivariate analyses were not attempted intentionally just to not make it over-burdened with heavy statistics. As a matter of fact, this exercise established first order trends, and thus identifying some of the focus areas for future studies

Conclusion

Importantly, this study could not only manage and organize the primary data and information on flora and fauna, but could also organize all the secondary data from various sources in GIS domain. This helped in generating various maps about the status and trends of various ecological and socio-economical parameters. Thus, this study was able to discern key spatial patterns on important parameters. Unequivocally, such multi-dimensional spatial database actually fulfills one of the pre-conditions for giving long term focus to monitor socio-ecological conditions and issues at suitable administrative level i.e. talukas. More importantly, such database creation would help achieving information driven sustainable development objectives for the ecologically sensitive coastal region of Gulf of Khambhat.

As stated earlier, the study throws out some interesting trends for many ecological and socio-economical parameters, in order to take it to logical conclusion, it is important to find out the causes of some of those changes and thus the trend in land use types, irrigation area, area under different crops etc. Equally important is to identify key ecological/environmental and socio-economical effects (impacts) of above changes. In other words, unless the cause and effects of recorded trends are explored, it is very difficult to comprehend and identify measures for sustainable development in coastal region of Gulf of Khambhat. Simply looking into the trends and numbers won’t tell the complete and real ecological issues. For complete picture, the backward and forward linkages need to be explored. Only through some in-depth studies, proper assessment can be made. Thus, in order to comprehend the real ecological issues linked to various parameters and to identify and quantify some of these issues, pilot intensive surveys in some of the problem talukas need to be undertaken.

Finally, it is also realized that the users of this report may be expecting following two outputs: (i) the ecological ranking of all the talukas and (ii) broad area of intervention to improve ecological/environmental conditions problem talukas. The report deliberately avoided to produce above two outputs. For the first point, it is important to realize that even the earlier comprehensive efforts by GEC like preparing of State Environmental Action program (SEAP), actually failed to rank talukas by taking into account different parameters (like pollution, landuse changes, biodiversity losses, land degradation, industrial development, energy demands etc.) and integrating them to generate one ‘super index’ of ecological health. In practical sense, this is quite an ambitious task. However, at best SEAP presented the trends in individual parameters. Needless to say, this study also attempted to generate and analysed such trends. Drawing multiple regression and cross sectoral integrations from present data sets may lead to wrong conclusions.

For the second point, it is again very important to realize that in order to suggest possible interventions for promoting ecological/environmental improvement at taluka levels,

Conclusion

identification of problems and their root causes is must. However, by analysing trends of some of the parameter, this study is just able to record some of the apparent “symptoms” of the problem. Unless, some of the identified symptoms are tracked and understood systematically through independent yet interdisciplinary case studies, search for possible workable interventions is very difficult. And for that, we need to collect more evidences and information from field levels.

In conclusion, it can be said that this study is just an attempt to quickly organize secondary and primary data and analysed their spatio-temporal trends. This helped in identifying and indicating key symptoms of the problems. While present study stopped at that point, it actually suggest for follow-up case studies to further probing the problem at site level. Potential interventions can only emerge from those grass-root levels of understanding.
