Bt cotton in India: critique of a macro analysis

This paper is a critique of Srivastava and Kolady (Current Science, 2016; 110: 3-10) who reported a macro analysis of the benefits of Bt cotton in India using statewide average data. The analysis is in error with respect to the economic benefits, biological underpinnings, and the effects of Bt cotton technology adoption on resource-poor farmers growing rainfed cotton. Viable non-GMO high-density cotton alternatives that increase yields, reduce cost of production, and give higher net average returns were ignored. The authors argue for biotechnology adoption in other crops in India without providing data or analysis
