An interdisciplinary methodology is being developed to enable analysis of effects of agricultural policies and economic incentives on land use. A linear programming (LP) model that maximizes regional farm income subject to resource and sustainability constraints is used to select the best combination of options for land use in terms of cropping and livestock systems with defined technologies. Constraints can be set at various levels in the agricultural system: field, farm, subregion, or region. By distinguishing different farm types, the LP model explicitly takes into account the variation in resource availability at the farm level. The use of scenarios in the analysis of effects of policy interventions is demonstrated for Guácimo county, a subregion in the Atlantic Zone of Costa Rica. For this county, the methodology is used to analyse possibilities to formulate policy instruments for reducing the use of biocides.
