Energy Food Development Biodiversity Emissions
Trade-offn. a situation that involves losing one quality or aspect of something in return for gaining anotherquality 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.
Development pathways (scenarios) Food production: Avoid areas suitable for food cultivation Production target Forest preservation: Target degraded areas & avoid forests Business-As-Usual: Target most productive areas for oil palm Carbon conservation: Avoid lands rich in carbon Hybrid strategy: Consider all priorities Current production
Outcome variables… Forests & biodiversity Area required for oil palm Food production capacity Carbon stocks
GIS data layers: Overall land-use land-cover (WRI, MoF, Sekala) Suitability for oil palm (FAO-IIASA) Suitability for rice (FAO-IIASA) Biomass carbon (Ruesch & Gibbs) Peat soil carbon (WRI, MoF, Sekala)

GIS data layers: New GIS layer of intersected polygons (n>500,000): Overall land-use land-cover (WRI, MoF, Sekala) Suitability for oil palm (FAO-IIASA) Suitability for rice (FAO-IIASA) Biomass carbon (Ruesch & Gibbs) Peat soil carbon (WRI, MoF, Sekala)
New GIS layer of intersected polygons (n>500,000): • Each polygon assigned conversion probabilities… • BAU: proportional to relative oil-palm yield • Food production: inversely proportional to rice yield • Forest preservation: inv. proportional to habitat quality • Carbon conservation: inv. proportional to C-stock • Hybrid scenario: BAU*Food*Forest*Carbon

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
