Extreme Heat: A Growing Crisis for Food Systems

Extreme heat events are increasingly threatening global agriculture and food security, with their frequency, intensity, and duration rising sharply over the past half-century. This phenomenon acts as a 'threat multiplier,' exacerbating existing vulnerabilities in developing nations like India. India's reliance on monoculture, primarily rice and wheat, makes its food system susceptible to heat-related crop damage, impacting millions of agricultural workers.

The Indo-Gangetic Plains, India's food bowl, are at risk of reduced wheat yields due to terminal heat stress. Rice cultivation, crucial for India's calorie intake, also faces severe threats from rising heatwaves and unpredictable rainfall patterns. Globally, agricultural labor is projected to lose significant working hours to heat stress by 2030, with outdoor workers in India facing disproportionately high risks.

India's agricultural policy has historically prioritized production quantity over resilience, with subsidies favoring water-intensive crops and marginalizing climate-resilient millets. While efforts are underway to promote crop diversification, state-level incentives often contradict these goals. Furthermore, labor laws lack specific protections against escalating heatwave impacts, with advisories remaining largely non-binding.

Transforming agrifood systems for climate resilience requires structural realignment of fiscal incentives, phasing out support for water-intensive monocultures in favor of heat-tolerant crops like millets. Increased investment in research and development for climate-resilient crops is essential. Integrating sector-specific heat action plans into rural labor schemes and supporting aquaculture and forest-dependent economies will be crucial for achieving food security goals in a warming world.
