the asb partnership for the tropical forest margins: benchmark sites experience
DESCRIPTION
The ASB Partnership for the Tropical Forest Margins (originally founded as Alternatives to Slash-and-Burn in 1994) is a global partnership of over 90 research institutions, universities, NGOs, community groups and farmer groups. ASB is currently focussed on reducing deforestation and emissions from land use change, including forestry and agriculture, while ensuring viable livelihoods and enhancing social and environmental co-benefits. This presentation gives an overview of the ASB benchmark sites and lessons learned from the process.This presentation formed part of the CRP6 Sentinel Landscape planning workshop held on 30 September – 1 October 2011 at CIFOR’s headquarters in Bogor, Indonesia. Further information on CRP6 and Sentinel Landscapes can be accessed from http://www.cifor.org/crp6/ and http://www.cifor.org/fileadmin/subsites/crp/CRP6-Sentinel-Landscape-workplan_2011-2014.pdf respectively.TRANSCRIPT

Purpose of ASB Benchmark
sites (A mix of objectives)
• Understanding of key issues
• Cross-site comparison
• Observation
• Technology transfer for impact (But this did
not quite happen as funds ran short )
Key Issues
• Reducing
deforestation and
forest degradation
• Reducing Emissions
from All Land Use
(REALU)
• Trade-offs at Forest
Agriculture

Criteria for ASB Benchmark sites (I)

HIGH EXTRAPOLATION POTENTIAL: PANTROPIC PROBLEM DOMAIN
HIGH INTERPOLATION POTENTIAL?
Criteria for Choice of ASB Benchmarks (II)
Representation of Biome types
SITE BIOME

Equatorial rainforests of the
Indonesian and Malaysian
archipelago.
Claveria and Lantapan, Philippines Moonsoonal forests

Subtropical hill forests of
mainland mountain Southeast Asia
found in Thailand, Myanmar, Laos,
Vietnam, and southern China.
Criteria for Choice of ASB
Benchmarks (II)
• DOMAIN SIMILARITY VALUE (Multiple
Criteria- Largely bio-physical determinants
of plant growth)
• elevation, potential evapotranspiration, total
annual precipitation, precipitation in the driest
month, precipitation range, minimum average
monthly temperature, and maximum average
monthly temperature (Gillison 2000).
• Using domain potential mapping procedure
(Carpenter et al., 1993)
DOMAIN SIMILARITY VALUES
Criteria for Choice of ASB Benchmarks (III)
Range of Socio-Economic Conditions
A range of socio-economic conditions
under which deforestation occurs
• Some Examples:
• Western Brazilian Amazon encompasses two
colonization, and areas along the BR-362 highway
• Cameroon, Congo Basin – low but increasing
population density and traditional indigenous
slash-and-burn practices
• Relatively High Population Density and migration
dynamic in Jambi and
• Working partnership in sites
• Long term perspective of partnership (often including a
local and national partner involved)
• Ensures multiple perspectives / roles / skills
• Access
Criteria for Choice of ASB Benchmarks
(IV) Partnership and infrastructure
Range of partners (national
partners crucial)
BENCHMARK SITE CHARACTERISTICS
Specific Characteristics
• Gradients within sites: Land Use, agro-ecology
and Population Density = useful for capturing
dynamics
• Examples:
• Population and land use gradients in Cameroon Site
• Broad gradient from primary forests in the Jambi
area to degraded Imperata grasslands in Lampung
Province, including both indigenous farmers and
colonization projects as well as large-scale
plantations and logging companies
Cameroon- Site Gradients
FROM RELATIVELY INTENSE MARKET GARDENING IN HIGH
DENSITY AREAS TO FOREST IN LOW DENSITY AREAS
Sumatra- Site Gradients
Lessons: some fundamental
considerations
• Use of comparative Methodological
framework (site characterization, meta-land
use)
• The ASB Matrix
• Multiple scales (nesting)
• Long-term commitment and co-location
• Expect surprises
Meta-Land Use Framework
The ASB Matrix
Multiple-scale (nesting)/ The
relevance of the question….
• Started out in ASB as
a 10km x 20km
• -40- 80000ha ( in
four blocks in Jambi;
80000ha in Chiang
Mai
• Broadened to 1.5 M
ha for landscape
type interaction
questions
• Now 5 Million ha in
Cameroon looking at
deforestation drivers
at sub-national level
• In Tanjabar ( Tanjung
Jabung Barat District
looking at district
level planning
Scenarios of REALU
(Reduced Emissions
from all Land Use)
500k ha
Expect Surprises – therefore
be flexible(i)
• Despite
methodological
harmonization, data
quality can still be
varied
• Funding challenges
long term can
disrupt plans ( I.e.
technology aspects
of ASB not financed
for long time
• You can often stitch
up data of different
periods to have an
impact story from
different projects as
long as methods
match- e.g. ASB h/h
surveys in Ucayali,
Peru and RAVA data
(though not
planned
Expect Surprises, hence be
flexible (ii)
• Jambi was chosen
to be more towards
left of curve, but in
a short time moved
more to the right
(Mining becoming
more important due
to change in
government;
emergence of oil
palm)
Expect Surprises, hence be
flexible (iii)
• Vietnam added to
enable
understanding of
extreme left hand
side of the forest
transition curve
(which was of
course not very
prominent at
inception of ASB)
