Project Aim
Provide an evidence base for the linkages between field- and farm-scale sustainable agricultural intensification interventions and climate change mitigation and biodiversity conservation in Zambia (focus on Eastern & Lusaka Provinces)
Project Methods:
• Literature, data search and synthesis
•Participatory system dynamics modeling
•Spatial analysis
System dynamics modeling: feedback, stocks and flows, nonlinearity
Number of people

Degree of consensus among stakeholders
Degree of understanding of the system dynamics
Mediated modeling Typical result: consensus on both problems/goals and process leading to effective and implementable policies
Mediated discussion Typical result: Consensus on goals or problems but no help on how to achieve the goals or solve the problems
Status Quo Typical result: confrontational debate and no improvement
Expert Modeling Typical result: specialized model whose recommendations never get implemented because they lack stakeholder support

Land Cover in Eastern Province 2010-2110
Agricultural Forest Miombo Grassland Degraded
←17% loss
←22% loss
←22% loss
(Preliminary) Conclusions: • Smallholder farmers are not
dominant drivers of habitat degradation
• Conservation agriculture unlikely to affect habitat degradation either positively or negatively
• Focus should be on charcoal, large-scale commercial farming
• We don’t know much about poaching…or GMAs
• Eastern province may be okay…unless charcoal business expands
