MODAM is a bio-economic modelling system that functions as Multi-Objective Decision support tool for Agro-ecosystem Management. It simulates farmers´ decision behaviour underthe assumption of pure economic rationality. The model is a static, mixed integer, linear programming model, which was developed to evaluate policy effects on the decision
behaviour of farmers and on the corresponding
environmental effects of the farmer chosen farm
management practices. The tool allows to calculate scenarios for different goal attainment levels (so called goal driven scenarios) as well as the computation of scenarios of different policy instruments (policy driven scenarios).
