The
two major objectives
of the ASB programme
in Phase III are:
-
To
improve and sustain
agricultural productivity,
rural livelihoods
and the environmental
services of tropical
forests and agroecosystem
mosaics at the
watershed and
landscape level.
-
To
collaborate with
local, national,
regional and international
stakeholders (from
land users to
policy-makers)
in the analysis
of institutional
and policy reform
scenarios to promote
the sustainable
implementation
of these agroecosystem
mosaics.
Both
of these objectives
must be addressed
at broader scales
than previously
in ASB, for four
main reasons:
- Land
uses are distributed
across the landscape
in a mosaic, and
the components
of this mosaic
interact in a
complex and non-additive
manner.
For example, a
farmer's field
may have a high
above-ground biodiversity
level, while an
entire landscape
of such fields
would result in
a relatively low
biodiversity across
that landscape.
Understanding
and predicting
landscape level
effects is therefore
not simply a question
of extrapolating
farm level data
to larger spatial
scales through
addition of farm
level effects.
- Land-use
mosaics provide
different functions
to households
and communities,
each with their
own goals and
needs.
The short and
long term dynamics
of these mosaics
and their components
are influenced
by complex social,
economic, institutional,
and biophysical
factors.
- Land-use
mosaics have direct
and indirect impacts
on a range of
different agroecosystem
functions,
and the aggregate
effect of the
interactions determines
both social and
environmental
sustainability
within a landscape
and a region.
- The
concerns of regional
and national policy
makers involve
different factors
than those of
either smallholder
farmers or international
environmental
groups.
The
key questions that
the ASB programme
proposes to address,
and which will yield
the core hypotheses
of Phase III are:
-
How
does agricultural
productivity and
its associated
technologies fit
into sustainable
landscape management?
-
Given
current and potential
('best-bet') land
uses in slash-and-burn
areas, how much
of each alternative
practice is needed
in the landscape
to attain food
security and alleviate
rural poverty
while minimising
environmental
costs for the
national society?
-
What
types of landscape
mosaics will minimise
tradeoffs between
agricultural and
environmental
concerns in different
countries?
-
What
policies, institutional
changes, collective
action scenarios,
and adoption rates
are needed to
implement the
landscape mosaics
that will yield
acceptable agricultural
and environmental
tradeoffs in different
countries?
-
What
is the best way
of channelling
ASB outputs to
policy-makers
and land users
and integrate
results regarding
landscape management
into national
planning schemes?
-
What
is the most effective
way of transferring
and disseminating
technology results
to forest margin
dwellers and help
guide the adoption
(and further adaptation)
of 'best bet'
on a large scale?
