| Among the most problematic issues considered as part of IFPRI’s 2020 Vision initiative, which seeks to develop an international consensus on how to meet future food needs while reducing poverty and protecting the environment, are the environmental questions. And the issues addressed in this discussion paper is particularly difficult. How is land degradation affecting the ability of farmers to produce adequate food supplies today, and what is the prognosis for the year 2020? As populations grow, farmers are forced to cultivate smaller and smaller plots, where the soil eventually becomes depleted, or they expand onto marginal lands-fragile hillsides, semi-arid areas, cleared forestland.

| In this paper we will try to address two questions. First, are farmers using the level of nitrogen that would maximize profits, and second, does the profit maximizing level of nitrogen use exceed the social optimum? In the latter case, we determine the optimal level of nitrogen use for continuous corn when the farmer must try to maintain the groundwater quality level at 10 ppm (the EPA safe drinking water standard). We conclude with recommendations concerning how to achieve the social optimum level of nitrogen use. |
