Increasing effectiveness of Kerinci Seblat National Park, Sumatera, through a landscape approach: Lessons learnt from Merangin

52nd Annual Meeting ATBC 201512-16 July 2015Honolulu, Hawaii

Background

• This study focuses on Kerinci Seblat National Park (TNKS), the largest National Park in Sumatra, which spans lowland, montane, and pine forest ecosystems.

• TNKS is home to rich biodiversity, which lately is threatened by loss and fragmentation of habitat.

• The role of agroforestry is not recognized while rich literatures show that matrix matters within landscape mosaics.

Kerinci Seblat National Part

• Establishment: 1982• Area: 1,342,662 Ha • Shape: elongated cover about 350 km

of Barisan Range Forest from Northwest to Southeast

• Mosaics of undisturbed forest• Elevation ranges from 100 to 3400

a.s.l

Ecoregion• 1.46% of Sumatran montane forest• 12.79 % of Sumatran lowland forest• 20.33 of Sumatran Tropical pine forest

• Proximity to NP is used to delineate zones: from core, to buffer area outside NP up to 15 km

• Sixteen districts in three provinces share the NP and buffer zones

LULCC in NP and surroundings

• Due to high population growth, in-migration, and external market demand, encroachment to TNKS during 20 years period is rampant (240,262 ha forest loss or 17% area)

• In the area surrounding TNKS, conversion of more integrated land-use system such as agroforestry into more intensified uses, especially estate crops, has been active (109,389 ha less of agroforest area and 212,981 ha of increased in estate crops).

Characterizing habitat changes

• Similarity in habitat qualities across land use/cover classes

• Landscape configuration• Integration of focal area to the landscape• Land sparing or land sharing?

Contrast Table – Plot level

Land Cover Type Forest

Agroforest 0.4

Timber plantation 0.9

Estate crop 0.9

Shrub 0.6

Configuration: Total Edge Contrast Index (TECI) – Landscape level

Total edge contrast index (TECI) of dense forest is calculated using Fragstat (McGarigal, 2002) as:

for each pixel of size 1 ha in the landscape, where:

– ei is total length (m) of edge in the sub-landscape between dense forest pixel and any other land use/cover type i

– di is the dissimilarity (edge contrast weight) between dense forest pixel (or other defined focal habitat) and any other land use/cover type i

(100)

Land-Use planning for Multiple Environmental Services (LUMENS)

• Build common visions and understandings among working groups of multiple stakeholders

• Collect and compile best available relevant dataset: land admin, plans, land use/cover maps, biophysical, demographic, socio-economics

• Strengthen capacities in:– quantifying ecosystem functions– analyzing trade offs between conservation-development– developing options and simulating scenarios– negotiating best scenarios over ex-ante impact analysis– implementation, monitoring and evaluation within the existing policy

framework• Facilitate and negotiate public consultations and high level discussions

to mainstream plans into programs of local government and identify other potential financing mechanisms

• Align and engage with policy processes at the local and national levels

• One of Jambi’s 11 districts. Area: 7,680 km2 with 336,000 people in 2010. The district’s population density of 45 per km2

• The upper watershed of Merangin is located in Kerinci Seblat National Park. It is an “average” district within the surroundings of NP, in terms of poverty, oil palm establishments, GDP, road density, etc.

• About 71% of area is allocated as forest land. The rest is non-forest land, owned privately or managed by communities or estate companies

• In 2011, ICRAF facilitated the establishment of a working group in Merangin that included various stakeholders in land-use planning: the District planning and Development agency, Forestry office, researchers and NGOs

•Understanding drivers•Where are likely changes will happen

based on the driver modelling •Changes in drivers can be

accommodated, i.e., new road. •Projected conversion areas can be

resulted from: (i) Exogenous process, perhaps from

regional or global models, (ii) Historical LULCC rates in each PU, (iii) Forward-looking scenario, with

considering future needs for lands to improve economics and social performance

Scenario development

• “Business as usual” (BAU): historical changes in each PU were retained, assuming a stationary process and drivers, 2005–2010 and 2010–2015;

• “Expansive agricultural development” (Expand): increased conversion of forests to oil-palm and acacia plantations and agroforests;

• “Green development” (Green): all undisturbed and most logged-over forests were retained and degraded areas in protected forests were rehabilitated. Oil-palm, acacia and rubber plantations and agroforests were only established on shrub-, grass- and cleared land.

Developing scenarios that change trajectories of future LULCC from BAU scenario based on local plans, e.g.• Green development scenario:all undisturbed and most logged-over forests were retained and degraded areas in protected forests were rehabilitated. Oil-palm, acacia and rubber plantations and agroforests were only established on shrub-, grass- and cleared land.

• Decrease of GDP due to decreasing area of forest cover that supports two key sectors: Wood log and Wood chips

• GDP decreases: 0.7% with GREEN Scenario), 1% with EXPAND Scenario and 1.7 % with BAU

• Although GDP from Oil palm, Rubber, Coconut and Coffee are increased it does not significantly contributes to Merangin GDP

• No oil palm processing facility in the district -> multiplier effect to other sectors are low

• Decrease of Labour absoption mostly due to two key sectors: Wood log and Wood chips

• Labour absorption will decrease: 5% with GREEN Scenario), 9% with EXPAND, and14 % with BAU

• Although labor absorption in Oil palm, Rubber and Coffee sectors will increase, labor absorption in other land based sector will mostly decrease, esp. since there was no oil palm processing facility in the district

Conclusions• Inclusive, informed, integrative LUP process to LEDS and beyond are

needed• Linking science-policy-practices is more feasible with negotiation

support systems rather than decision support systems• No one size fits all: local specificity is crucial, understanding drivers to

identifying leverage points• Capacity strengthening is key to transformation of landscape governance • Aligning local and global agenda is an important entry point to

sustainable actions• Multiple ES, beyond carbon, such as water through land-based sector

can bring together mitigation and adaptation• Synergy across levels and modalities through landscape approach is key

to implementation at local level
