Tradeoff Analysis System: Policy Decision Support for Agriculture
To make informed decisions, public and private decision makers need accurate information about the economic and environmental consequences of agricultural systems. Tradeoff Analysis is a process designed to link decision makers to teams of scientists with tools that can provide this information.
Public stakeholders Policy makers Scientists Research priority settingProject design & implementation Inform stakeholders Identify sustainability criteria Formulate hypotheses as potential tradeoffs Identify disciplines for research project Identify models and data needs define units of analysis Collect data and implement disciplinary research Tradeoff analysis process

Economic principle of opportunity cost Intuitive appeal Easy-to-understand (2-d) Quantifies concept of sustainability Represents risk: joint distributions of outcomes –Health risk thresholds –Climate vulnerability A useful way to communicate properties of complex agricultural systems: Tradeoff curves
Examples Economic – environment – health tradeoffs associated with pesticide use (Ecuador study, see www.tradeoffs.montana.edu) Sustainability of agriculture on steeply sloped hillsides (hydric and tillage erosion, terracing, carbon). Carbon sequestration as a mechanism to finance adoption of sustainable production systems and institutions.
