8. Short model description
Goal of model development:
• Represent continuum of ‘subsistence’ to ‘market integration’, shifting
cultivation to permanently cropped fields, labour + cash constrained
decisions in a ‘tropical forest margin’ setting
• Dynamics of soil fertility (~ Trenbath) and (agro)forest resources
• Relate dynamic knowledge of landscape agents to dynamic action
(decision making) in ‘adopt & learn’ mode; open to impact analysis of
‘extension’
• Explore spatial dynamics, consequences of land use zoning, restrictions
to access
• Tradeoff and scenario analysis of livelihoods & ES (C-stocks,
biodiversity, key watershed functions)
• Use in spatial planning and scenario development boundary work
Typical research questions addressed:
1) Can we account for historical land use change of a study area
(calibration/validation phase)
2) What can we expect (‘scenarios’) of ‘business as usual’ extrapolation
compared to specific interventions in spatial planning, demographic,
economic, K-dynamics, PES-incentive systems
9. Short model description
maximizing ‘utility’ ‘model inside the model’:
(profitability)
• Diagram dynamic knowledge - learning
(external-extension and
of model internal - experience)

18. Multipurpose agroforestry as a climate
change resiliency option for farmers: an
example of local adaptation in Vietnam
Quan Nguyen, Minh Ha Hoang, Ingrid Öborn, and Meine van Noordwijk
Recently, the Commission on Sustainable
Agriculture and Climate Change (Beddington
et al. 2011) launched its recommendations for
ensuring food security under a changing
climate. The report does not mention trees,
forests or agroforestry as important for food
security. This is in contrast to the ways farming
traditions have evolved (van Noordwijk et al.
2011) and how farmers currently try to adapt
to further climate change.
