Evolutionary Processes in Soil Conservation Policy
梳理了美国土壤保护政策的历史与演化过程，识别其背后的社会目标，并与经济学认定的政府合法目标对比，指出土壤保护对水质和农业未来的持续重要性。
This paper summarizes and interprets part of the history and some of the apparent evolutionary processes of past soil-conservation policy, and identifies the underlying social objectives of these policies. The findings are compared to those social objectives that economics identifies as the legitimate pursuits of government. It concludes that soil conservation will continue to be an important policy concern as institutions mature and nonpoint pollution policy becomes better developed because of its persisting relevance to both water quality and the future vitality of agriculture. 23 references.
