Trade-off n. a situation that involves losing one quality or aspect of something in return for gaining another quality or aspect. It implies a decision to be made with full comprehension of the upside and downside of any choice.
Develop science-based decision-support tools to help decision makers evaluate trade-offs of pursuing alternative development options.
Where & How?
Production target Business-As-Usual: Target most productive areas for oil palm Forest preservation: Target degraded areas & avoid forests Food production: Avoid areas suitable for food cultivation Carbon conservation: Avoid lands rich in carbon Hybrid strategy: Consider all priorities Development pathways (scenarios) Current production
Outcome variables… Area required for oil palm Forests & biodiversity Food production capacity Carbon stocks
Suitability for rice (FAO-IIASA) Suitability for oil palm (FAO-IIASA) Overall land-use land-cover (WRI, MoF, Sekala) Biomass carbon (Ruesch & Gibbs) Peat soil carbon (WRI, MoF, Sekala) GIS data layers:

Conclusion Every single-priority scenario produced tradeoffs in other priorities
Conclusion Every single-priority scenario produced tradeoffs in other priorities Tradeoffs could be minimized through implementation of properly planned and spatially explicit development strategy
