The linear programming model maximizes farmers net income over time under constraints of risk aversion, food consumption, land area, soil fertility, labor and cash availability. The model is recursive, meaning that results from one period are carried over into the next period. The agronomic attributes are specified for each type of land in the landscape, and detailed agroecological factors determine the main processes of land degradation. When the population grows and the market expands, the model adopts the most cost effective techniques. Several simulations are carried out to the year 2030.
