UN Report Highlights Heatwave Threat to Indian Agriculture and Workers
A new report from the United Nations' Food and Agriculture Organization (FAO) and the World Meteorological Organization (WMO) has issued a stark warning: heatwaves are set to become a major threat to Indian agricultural workers and rice production. The most intense risks from future extreme heat events are concentrated around the densely populated farming regions of the Ganges and Indus River basins, areas critical to India's food security.
Impact of Extreme Heat on Farm Output
Released on World Earth Day, the report provides a detailed analysis of how extreme heat affects the output of rice and other agricultural produce in India. It cites the extreme heat events of 2022 as a prime example, noting that abnormal rises in both maximum and minimum temperatures that year impacted crops, fruits, vegetables, livestock, and poultry in over one-third of Indian states and union territories. Affected regions included Punjab, Haryana, Rajasthan, Jammu and Kashmir, Himachal Pradesh, Uttar Pradesh, Madhya Pradesh, Bihar, and Maharashtra.
The report describes 2022 as a classic case of the combined effects of high temperatures and reduced rainfall, particularly felt in northern and central India's agricultural production systems. This warning comes at a crucial time, as forecasts predict 'below normal' rainfall during the four-month monsoon season from June to September this year, potentially exacerbating heat-related stresses.
Rising Frequency and Risks of Heatwaves
According to the WMO, heatwaves are defined as prolonged periods of abnormally hot weather, lasting from several days to months, when both day-time and night-time temperatures exceed typical regional averages. The report notes that globally, the frequency, intensity, and duration of extreme heat events have risen sharply over the past half-century. Risks to agrifood systems and ecosystems are expected to soar in the future, posing significant challenges to sustainable agriculture.
WMO Secretary-General Celeste Saulo emphasized, "Extreme heat is increasingly defining the conditions under which agrifood systems operate. More than simply an isolated climatic hazard, it acts as a compounding risk factor that magnifies existing weaknesses across agricultural systems." She highlighted the importance of early warnings and climate services, such as seasonal outlooks, to help communities adapt to this new reality.
Broader Impacts and Adaptation Measures
Beyond crops, the report details how extreme heat affects livestock species, fisheries, dairy animals, and poultry products, underscoring the widespread vulnerability of India's agricultural sector. To mitigate these impacts, the report calls for innovation and the implementation of adaptation measures. Key strategies include:
- Selective breeding and crop choices adjusted to the new climate reality.
- Adjusting planting windows to avoid peak heat periods.
- Altering management practices to shelter crops and agricultural activities from extreme heat effects.
The report stresses that early warning systems are a particularly important tool, aiding farmers in their efforts to respond proactively to extreme heat events. By adopting these measures, India can better safeguard its agricultural productivity and protect the livelihoods of millions of farm workers in the face of escalating climate challenges.
