Conservation Reserve and Conservation Compliance Programs: Implications for Resource Adjustment
分析1985年《食品安全法案》中的保护储备计划（CRP）和保护合规计划（CC）如何影响土地利用、商品市场、投入品使用、生产成本和环境，发现扩大CRP会降低库存并提高商品价格，而保护合规则改变种植模式和技术选择，导致生产成本上升2-4%，净农场收入下降6-15%。
Conservation Titles of the 1985 Food Security Act lead to agricultural market and resource use adjustments. This study explores how the Conservation Reserve Program (CRP) and the Conservation Compliance (CC) Program influence land use, commodity markets, input and technology use, production costs, and the environment. In the case of the Conservation Reserve Program, CARD/FAPRI commodity models are used to generate a baseline and to evaluate the impacts of increasing the amount of land in the reserve. In the case of the Conservation Compliance Program, the CARD ARIMS model is used to generate a baseline without the program and then to evaluate the impacts of imposing erosion restrictions consistent with the conservation compliance provisions.\nLower stocks and higher commodity prices would be consequences of expanding the CRP. Resource adjustment associated with conservation compliance can be protracted and may be costly. Insofar as CRP reduces production and strengthens prices, it also can have the effect of increasing the intensity of input use in the remaining planted area. Conservation compliance clearly influences cropping patterns and choices of technology, as well as rates of soil erosion. While production cost increases of 2-4 percent seem relatively small, this could mean as much as 6-15 percent decline in net farm income.
