Pesticide Use and Fish Harvests in Vietnamese Rice Agroecosystems
利用越南湄公河三角洲的调查数据，估计农药使用对稻田鱼类收获的影响，发现农药确实损害鱼类种群，但损失小到忽略不计在经济上可能是合理的。
Abstract Criticisms of the Green Revolution have focused on environmental and human health problems associated with pesticides. Pesticides may also have adverse effects on wild fish and other aquatic animals in rice paddies that supply an additional source of food and income for some farm households and provide natural pest control. We use survey data from the Mekong Delta region of Vietnam to estimate the impact of pesticides on fish harvests from rice fields. The results confirm findings of ecological studies that pesticide use harms fish populations. However, fish harvest losses are small enough that ignoring them is likely economically rational.
