The ‘Global Food Policy Report 2022’ has warned that summer heatwaves in Pakistan are expected to increase at a pace of 0.71 day per decade, while in India they are expected to triple or quadruple by 2100.
, water shortage in Pakistan is expected to intensify as a result of climate change, according to the International Food Policy Research Institute (IFPRI) in Washington. According to the paper, Himalayan glaciers, which are a major source of rivers in South Asia, have lost more mass since 2000 than during the whole twentieth century.
Three of the world’s five basins with the biggest anticipated GDP losses due to water scarcity are in South Asia (Indus, Sabarmati, and Ganges-Brahmaputra). GDP losses in the Indus Basin alone are anticipated to top $5,000 billion by 2100, according to the report.
Glacier melt, sea-level rise, groundwater depletion, extreme weather events, and the frequency of natural disasters all provide immediate and long-term concerns for South Asia, which are expected to grow in the next decades. The analysis cautions that South Asia’s pre-existing vulnerabilities — high poverty, poor governance, and restricted access to basic services and resources — magnify the region’s climate risks, with potentially catastrophic consequences if warming continues at this rate.
With a few exceptions for particular crops and sub-regions, the region’s unparalleled suite of climate changes has also resulted in crop yield drop and production losses. Climate change is causing a drop in rice and wheat yields in Pakistan, however the introduction of heat-tolerant varieties has offered some resilience and delayed the worst effects.
