摘要：Farm resource allocation decision, particularly in developing countries, is generally a risky process. The uncertainty related to yields and farm product prices suggests that farmers behave in risk-averse ways. This research uses linear programming models under a risk framework to investigate about cropping patterns and technologies most profitable to farmers in two Senegalese zones: The Center of the Peanut Basin and the Upper Casamance. Normative supply responses are derived for the two agricultural zones investigated under a food security perspective by making assumptions about farm price levels. In the Central Peanut Basin, acreage under cultivation does not respond to price increases; supply responses have constant slopes. In the Upper Casamance zone, interesting aspects of land competition between crops is found. Among all crops, maize showed higher acreage responses to price increases.
