According to a joint report by the FAO and WMO, extreme heat could make agricultural work unsafe for up to 250 days a year by the end of the century in regions like South Asia, tropical sub-Saharan Africa, and parts of Central/South America. This risk threatens over 1 billion livelihoods and reduces labour capacity, as heat stress causes, crop yields to fall.

Key Impacts of Extreme Heat on Agriculture: Unsafe Working Days: - Over two-thirds of the year could become unsafe for outdoor labor, particularly affecting farming in tropical and subtropical regions. Health Hazards: - Farm workers are already 35 times more likely to die from heat exposure than other workers, with risks including heatstroke and chronic kidney disease. Declining Yields: - Crop yields are expected to fall by 7.5% per 1'C rise in temperature. Livestock Mortality: - Heat stress begins for common species at about 25∘C, reducing dairy yields and causing cardiovascular shock in pigs and chickens. Compound Risks: - E...
