New climate change report warns of rising floods, droughts, and threats to India’s food security

The study aims to usher policymakers, educators, and NGOs successful processing targeted strategies to mitigate clime alteration impacts and safeguard susceptible communities.

Key findings see changes successful temperature, monsoon and wintertime patterns. Changes successful somesthesia poses 2 scenarios, a mean “Middle of the Road” emanation script and a high-emissions path, which is the “Fossil-Fueled Development” emanation scenario.

The study projects that by 2057, India’s yearly maximum somesthesia volition emergence by 1.5°C nether the mean emissions scenario, with this summation occurring a decennary earlier nether the high-emissions pathway.

Under the low-emission script (SSP2-4.5), 196 districts volition spot a summertime maximum somesthesia emergence of astatine slightest 1°C, with 70 districts experiencing akin yearly maximum somesthesia changes. Leh is expected to grounds the highest emergence astatine 1.6°C for some summertime and yearly temperatures. Meanwhile, wintertime minimum temperatures are projected to summation by 1.5°C oregon much successful 139 districts.

Under the high-emission script (SSP5-8.5), 249 districts are expected to acquisition an yearly maximum somesthesia emergence of astatine slightest 1°C, with 16 Himalayan districts exceeding 1.5°C.

Leh volition again grounds the highest summation astatine 1.8°C. During summers, 517 districts volition spot a somesthesia emergence of 1°C oregon more, with 17 districts surpassing 1.5°C and Leh reaching 1.7°C. Winter minimum temperatures could emergence by 1.5°C oregon much successful 162 districts, with Anjaw successful Arunachal Pradesh seeing the steepest summation astatine 2.2°C.

Over 24 districts successful coastal and eastbound Himalayan regions are projected to look wet-bulb temperatures exceeding 31°C, posing terrible wellness risks.

The study besides highlights shifts successful precipitation patterns and monsoonal activity. Western states likez Gujarat and Rajasthan are projected to spot a 20-50% summation successful yearly rainfall, portion northeastern states similar Arunachal Pradesh and Sikkim could look rainfall deficits of up to 15%.

The southwest monsoon is apt to intensify successful the westbound portion the northeast monsoon weakens. Higher-altitude regions, specified arsenic Ladakh and the Western Ghats, are expected to witnesser accrued dense rainfall, triggering landslides and disrupt horticulture and accepted housing.

At the aforesaid time, northeastern states babelike connected rain-fed agriculture whitethorn look drought-like conditions, threatening agrarian livelihoods.

Given India’s dense reliance connected monsoons for agriculture, the projected changes successful precipitation, coupled with rising temperatures, could disrupt nutrient security, exacerbate flooding, ungraded erosion, and droughts, and summation the hazard of vector-borne diseases.
