Abstract

The Sao Paulo State Watershed Program was drawn with multiple objectives to be optimized through planning of sustainable agricultural activities. Important dimensions that must be considered in implementing this program are farmer’s specific objectives and farm restrictions. This work presents a method for planning land use in a sustainable way, using Lexicographic Goal Programming to plan the mix of activities for each farm. These objectives are: minimization of runoff effects, pesticide use, seasonal income variability, and seasonal demand for labor; and maximization of farm gross margin, basic staple production, and resident labor use. The optimization process pointed to activities that affected the farm system (crop layout, labor, machinery, and pesticides use, gross margins, staple production, and soil conservation) in different ways. More acceptable solutions to farmers ’ multiple objectives were suggested through the planning land use.
