Soil conservation and governmental policies in tropical areas: Does aid worsen the incentives for arresting erosion?
通过微观经济模型分析农民在耕作、土壤保持和非农工作之间的选择，指出政府支持小农户的政策若设计不当，可能削弱土壤保持的激励，需关注土地质量和土壤保持净收益的分布。
This paper focuses on how farmers respond with respect to the adoption of soil conservation measures to governmental agricultural policies aiming at supporting smallholders. A simple micro-economic framework was chosen to undertake an analysis of farmer choices among three activities; farming, adoption of soil conservation measures and off-farm work. The model shows that governments have to be cautious when designing support measures if improved resource management is a policy goal. In the design of such measures, attention has to be paid both to (1) the distribution in land quality, and (2) the distribution in the net returns from adopting soil conservation measures.
