It’s a widespread and intensely personal issue, one that has been difficult to tease out the root source. Debt, mental health, lack of social services, weather vagaries and even media coverage have all been put forward as part of the problem. Now, recent research published in the Proceedings of the National Academy of Sciences suggests that climate change could also be playing a role.
The findings attribute more than 59,000 suicides in India to rising temperatures since 1980. With the world expected to warm further, the results suggest that adaptation could play a key role in helping farmers.
“Suicide is a heartbreaking indicator of human hardship, and I felt that if this phenomenon were in fact affected by a changing climate, it would be essential to quantify its effect and consider this relationship as we build climate policy for the future,” Tamma Carleton, a PhD student at the University of California, Berkeley who authored the new study, said.
Agriculture makes up 14 percent of India’s GDP, but employs 230 million people or 32 percent of the rural population. Roughly two-thirds of those farmers have poor access to irrigation and rely on rainfed agriculture, itself a crapshoot tied to the Indian monsoon. That leaves them vulnerable to not just drought but other climate shocks like rising temperatures.
“These farmers and agricultural workers face extremely stressful and difficult conditions,” Carleton said. “In this risky environment where families are very poor, any additional shock can lead to extreme economic destitution, and some individuals may cope with that hardship by committing suicide. I find that the climate, and temperature in particular, causes crop losses while also elevating the risk of suicide.”
The study shows that there’s a strong link between high…
