Bt Cotton and Farmer Suicides in India: An Evidence-based Assessment
系统评估了Bt棉花与印度农民自杀关系的证据，发现整体上Bt棉花技术有效，且无自杀率回升证据，但在特定地区和年份可能间接导致农民负债和自杀，这主要归因于种植环境而非技术本身。
Bt cotton is accused of being responsible for an increase of farmer suicides in India. In this article, we provide a comprehensive review of evidence on Bt cotton and farmer suicides. Available data show no evidence of a 'resurgence' of farmer suicides. Moreover, Bt cotton technology has been very effective overall in India. Nevertheless, in specific districts and years, Bt cotton may have indirectly contributed to farmer indebtedness, leading to suicides, but its failure was mainly the result of the context or environment in which it was planted.
