Agricultural expansion has resulted in losses to habitats, forests, ecosystems and biological diversity. Socio-ecological research methods were used to assess the livelihood impacts of agrarian change across the forest transition in six tropical landscapes in Zambia, Burkina Faso, Cameroon, Ethiopia, Indonesia and Bangladesh. Early findings suggest the transition from a forested landscape to a more agrarian-dominated system does not immediately result in better livelihood outcomes, and there may be unintended consequences.

2. Agricultural expansion remains
major driver of deforestation
Transformation of natural systems
has resulted in significant
environmental degradation
Global food system is in crisis
(Global Nutrition Report 2016)
Belief that biodiversity conservation
and agriculture cannot co-exist
Ca.60% of world’s food originates
from diverse small-holder farming
systems in complex landscapes
Agro-ecological approaches being
advocated (e.g. IPBES 2016)
Need strong evidence-based for
implementation
Context
3. Agrarian Change Project: Research goals
An integrated landscape
approach to explore the
livelihood and dietary
implications of land-use
change and agrarian change
processes in six multi-
functional landscapes.
Provide insights into how
globally conceived land-use
strategies (e.g. land
sharing/land sparing
trajectories) manifest locally
and how they are embedded
into local histories, culture,
and political and market
dynamics.

19. Country-level results: impacts on
poverty and livelihoods
Indonesia: Major dietary transition towards processed foods which
has major impact on nutrition and health status
Bangladesh: Agroforestry seen as an important livelihoods
strategy but only for those with secure tenure
Ethiopia: Loss of forest has led to increased poverty due to loss of
common grazing land and access to fuelwood
Cameroon: Annexation of land for oil palm concessions has
resulted in land displacement and encroachment into protected
areas. Threatens future regional food security.
Zambia: Heavy policy emphasis on agriculture for food security at
expense of forests. Loss of safety-net function
Burkina Faso: Recurring droughts are increasingly common and
income from forest products (timber, fuelwood and NTFPs) are
important safety-net to purchase food during dry periods.
Continued forest loss will further jeopardise future adaptation
strategies
20. Conclusions
Across study regions, loss of forest to
agriculture does not necessarily result
in direct livelihoods benefits
Loss of forest has direct impact on
rural coping strategies
Diets inevitably transition with access
to income and markets, but not
necessarily for the better
Landscape mosaics are better at
achieving multiple benefits, including
ecosystem services and biodiversity
conservation, so landscape
configuration is important
Land sparing/sharing paradigm does
not necessarily play out in reality as it
implies some level of “grand design”
Contribution of forest products has
been dramatically underestimated for
both diets and income
This schematic diagram is a simplified way of looking at a mosaic landscape undergoing processes of Agrarian Change, taking into account decreasing forest cover and increasing levels of agricultural modification.
As you move across this gradient of agricultural modification, areas of natural vegetation largely decrease and patches of secondary vegetation and agroforestry systems emerge, as well as patches of agricultural land, and a further transition occurs as result of intensively cultivated agro-commodities, often in the form of agricultural monocultures such as wheat, maize and oil palm.
So over the last 18 months we’ve set this project up in 6 different countries and have identified landscapes in each country exhibiting both land sharing and land sparing scenarios. The case study countries we will examine are Burkina Faso, Cameroon, Ethiopia, Bangladesh, Indonesia and Zambia
And in each focal country, a focal landscape exhibiting changing land use practices and agrarian change has been identified to conduct the study.
We’ve applied a nested experimental design where in each landscape, there different land use zones have been identified, representing a gradient of agricultural modification and decreasing tree cover and with local communities present in each of these zones.
The suite of land use blocks or zones are representative of changes in land use practice and have a dominant land use. An example gradient of land use may be an area with best available forest cover and dependency on forest products coupled with subsistence agriculture, an agroforestry system (a mix of forest cover and crops), and a monoculture/intensive cash crop system (e.g. wheat or palm oil).
