Several states in the country are witnessing a decline in Southwest Monsoon rainfall, according to India Meteorological Department (IMD)
The report cites the numbers of five states- Nagaland, Bihar, West Bengal, UP and Meghalaya- witnessing decreasing trends.
Along with Arunachal Pradesh and Himachal Pradesh, the annual rainfall in these states showed a decline between 1989 and 2018.
The frequency of heavy rains have been witnessed in many parts of Saurashtra, Kutch Peninsula, South-west Rajasthan, Andhra Pradesh, north Tamil Nadu and many parts of Konkan, Goa and Uttarakhand.
The agricultural season gets hampered due to changes in monsoon pattern. Farmers may face the biggest losses in terms of crop output.
Monsoon is necessary for recharging groundwater and keeping constant flow in rivers and streams. Decline in rainfall will deplete water resources.
The country’s food security will be in peril as major areas of rainfall deficiency are located in fertile agriculture regions of the country.
The impact will also be severe on livestock and other animal rearing sector. Rural agro-economy will be the worst affected.
There will be an increased migration from rainfall deficient areas towards metro cities. Urbanization will further stress the resources of cities.
Monsoon is a seasonal wind system that brings moisture- laden clouds to cause rainfall across the region.
For the first six months, the wind blows from south-west side and the next six months it blows from north-east side.
