Farm-Level Evaluation of Agricultural and Environmental Policies with an Integrated Modeling System
通过集成经济与生物模型，分析美国玉米商品计划与限制玉米根虫杀虫剂使用的环境政策在农场层面的相互影响，发现政策调整可在小幅影响农场收入的同时减少杀虫剂使用、改善环境与健康风险。
Concern is growing throughout the United States about environmental and health risks associated with the use of agricultural chemicals. In response to these concerns, public policies designed to alter farming practices and the use of agricultural chemicals are being proposed and implemented. In addition, existing U.S. agricultural policies directed at price stabilization and income support are being reviewed for interdependencies with environmental measures.\nThis paper provides a farm-level analysis of the interrelationships between the current U.S. commodity program for corn and selected environmentally motivated policies for controlling the use of corn rootworm insecticides. An integrated modeling system is employed that includes economic and biological components. The farm modeled is for opportunities for coordinating agricultural commodity and environmental policies. Policy adjustments are identified that can reduce corn rootworm insecticide use, improving the quality of the environment and limiting health risk, while only modestly affecting certainly equivalent farm income.
