In South Asia, record heat threatens future of farming

-United Nations Environment Programme (UNEP)

A prolonged and deadly heatwave has hit large swaths of India and Pakistan affecting hundreds of millions of people and sparking food and energy shortages. Experts say the extreme heat is a grim preview of what the climate crisis has in store for a region home to over 1 billion people.

Temperatures in India’s capital and parts of Pakistan have at times reached close to 50°C, killing dozens of people in both countries and upending the daily lives and livelihoods of students, labourers, and farmers.

March was the hottest month on record in India since 1901. The extreme heat also came earlier in the year than normal, covered a huge landmass and persisted much longer than typical heatwaves.

The high temperatures have disproportionately affected farmers with little shelter from the heat and whose crops have wilted in the scorching sun.

“Extreme heat has major repercussions for the agricultural sector,” said Sumalee Khosla, Climate Change Adaptation Finance Expert at the United Nations Environment Programme (UNEP). Climate-related heat stress will increase drought and exacerbate water scarcity for irrigation. This impacts farming communities and potentially creates further food security issues in affected countries.”

Food insecurity is already being felt in the region. India, the world’s second-largest wheat producer, banned wheat exports to stave off shortages. This decision has reduced wheat supplies and caused a spike in prices around the world.

The prolonged heatwave exacerbated by the climate crisis has played havoc with planting and harvesting seasons. It is part of a trend that is seeing summers come earlier and the monsoon come later, said James Lomax, a Sustainable Food Systems Officer at the United Nations Environment Programme (UNEP). The late planting season has meant that wheat was still growing when the heatwave hit, resulting in yield reduction.
