Knowledge sharing versus climate change.

A resource for effects mitigation in Malika, Senegal

involvers- the relationship of the local authorities , the private

sector and the civil society

Complementation- autonomous and planned adaptation

Experimental process- building adaptive capacities,

knowledge sharing and delivering adaptations

Case study Malika, a peri-urban area of Dakar

sub- Saharan African territories in which the increased in

flood since 2005 are undermining citizens daily life and

agricultural activities.

Activities

Community engagement

( government & traditional)

The community level discussion

(the developing city onspreading knowledge.

The natural territorial course

Identification ofpotential or vulnerability

filling the questionair

Discussion of local andexternal practices andstrategies

Autonomous adaptive capacity to environmental change in

peri-urban Dar es Salaam

Problem- In Dars peri-urban area , the dependence on

natural resource make them vulnerable to environmental

changes

the crucial factors in adaptive capacity at local level- the

livelihood strategies, autonomous adaptation and

environmental management practice

Methods- the field work

Solution- a need for understanding and multiple adaptation

strategies in local level and he informing decision making

process

Vulnerability = Exposure + Sensitivity Adaptive capacity

V = E + S - A

Vulnerability is the degree to which a system issusceptible to and unable to cope with adverseeffects of climate change

Adaptive capacity(focus): the capability to modify exposure to risks

associated with climate change , absorb and recover from losses

stemming from climate impacts and exploit new opportunities that

arise in the process of adaptation.

Exposure : The character, magnitude and rate of climate change

and variation to which a system is exposed to.

NGEMA project- neighborhood growth and

environmental management in Dar es Salaam, Tanzania

Project introduction

preliminary design of an urban area of approximate10000 people

Site: Des Temeke municipality in Des. Lower urban development :a colossal project - a new settle- Kigamboni - a pure visionary

project

NGEMA priority objective -

Sustain the agriculture( US) as a model for a sustainable economic and environmental

growth of the cityProvide basic urban infrastructure

Create a multi-fuctional

Integrate commercial and integrate commercial are residential space

Sustainable buildings and renewable energy

Vulnerability to Flood in Maputo, Mozambique

ProblemOn the 15th of January 2011 a rainfall of 200mm

devastated Maputo

Risk assessment developed by M.Tiepolo for Agriconsulting

with UNHC&CCI

R = (H X V X E)/ A

R- riskH- hazard

V- exposure

A- adaptation

NoteField visits are to identify vulnerability since the minor altimetry variations

may be invisible in DEM analysis or topographic maps.

A cross check with after rain on- field inspection is essential.

1 Poverty

2 The rate of land

covered by roofs

and tree canopy

3 The soil type

4The watershed size

Adaptation to climate change in Maputo, Mozambique

Study goal

identify ongoing measures in Maputo Municipality

Define, prioritize and timing future measures

R = (H X V X E)/ A

A panel of 33 adaptation measures in 8 most flood zoon and

3 main area prone to see level rise

8 interviews after field visit conducted by technicians andbairro secretary general

A group discussion between 6 municipal environment

department employees to defined the importance of the

measurements and to gather opinion on future measuresusing 5 predefined criteria for judgment

Reducing the vulnerability of unban contexts in the

rural Mozambique through spatial planning

African rural towns are

instable due to exogenous

factor (civil war

globalization of theeconomies and CC.

essential urban characters

Linking vulnerability, resilience and change:

a study in Caia district, Mozambique

The emergencies are multi-faceted and the result is not ofphysical events alone

Address the social- cultural andenvironmental consequences ofloss of the land in Caia.

The result shows that is current

policy is not addressing the realcause of poverty and access tonatural resources as priority.

Early warning practices in a climate change

The global upward trend in natural disasters occurrence, in

particular hydro meteorological ones

In the early warning for flooding, 2 instruments are

presented:ERDS- extreme rainfall detection system, based on the

analysis of historical rainfall values derived from TRMM dada

provide vulnerability maps derived from the analysis of time

series of MODIS data A system based on satellite vegetation indices for the

monitoring the drought induced vegetation stress.
