This paper presents a bio-economic model of Andit Tid, a severely degraded crop-livestock farming system with high population density and good market access in the highlands of Ethiopia. Land degradation, population growth, stagnant technology, and drought threaten food security in the area....

This paper focuses on the economic consequences of droughts for the irrigation sector. We develop a dynamic-recursive mathematical programming farm model that assumes imperfect mobility of capital and labour as well as rational expectations about future water availability. The model is...

The problems caused by water scarcity demand important changes in the criteria and objectives of water policies. The agricultural sector in Spain consumes up to 80% of all available hydric resources and the need to increase the efficiency of current uses of water in the agricultural sector is at...

Degradation of land continues to pose a threat to future food production potential in many developing economies. Various approaches, mainly based on command-and-control policies, have been tried (with limited success) in the past to encourage adoption of erosion-control practices by farm...
