How interventions to mitigate climate-caused poverty and inequality in India came at a cost to environmental sustainability.In the monsoon regions of South Asia, the rainy season sustains life but brings with it the threat of floods, followed by a long stretch of the year when little gainful work is possible and the threat of famine looms. Beginning in the late nineteenth century, a series of interventions by Indian governments and other actors mitigated these conditions, enabling agricultural growth, encouraging urbanization, and bringing about a permanent decrease in death rates. But these actions―largely efforts to ensure wider access to water―came at a cost to environmental sustainability. In Monsoon Economies, Tirthankar Roy explores the interaction between the environment and the economy in the emergence of modern India. Roy argues that the tropical monsoon climate makes economic and population growth contingent on water security. But in a water-scarce world, the means used to
