The CSE report also emphasised that Indian farmers are reeling under extreme weather events and need protective measures.
Farmers have lost more than 100 lakh tonnes of Rabi crops, valued over Rs 20,000 crore, due to unseasonal rainfall and hailstorm in February-April this year, the Centre for Science and Environment (CSE) said in a report.
As a result, India may have to import 10 lakh tonnes of wheat in the current year as about 68.2 lakh tonnes were damaged due to unseasonal rainfall in the last Rabi season, the CSE said in its report 'Lived Anomaly'.
In February-April 2015, standing crops on 182.38 lakh hectares or 29.61 per cent of the entire Rabi sown area were affected. Six-seven per cent of this was wheat crop.
"The fall in production of major foodgrain crops was about 86.3 lakh tonnes, which translated to a loss of Rs 15,777 crore worth of foodgrains. A fall in production of oil seeds by 14.1 lakh tonnes meant an additional loss of Rs 4,676 crore. The total economic loss was about Rs 20,453 crore", the report said.
As per the CSE estimates, 40 per cent of the wheat cultivated area, 14 per cent of area under pulses and oil seeds, and four per cent of coarse cereals were affected by rain and hailstorm.
"We spent some time in converting crop loss into monetary figure taking just the minimum support price and if you look at this figure...excluding the horticulture loss, Rs 20,000 crore stands just for foodgrains and oilseeds", CSE Deputy Director General Chandra Bhushan said.
The report also emphasised that Indian farmers are reeling under extreme weather events and need protective measures to ensure that Country's largest occupational sector, agriculture, does not decline further.
"We are seeing an increased severity and frequency of extreme weather events. Farmers in India are facing the double blow of agrarian distress and extreme weather events as a result of climate change. A series of measures including better protection mechanisms are needed to support them", CSE Director General Sunita Narain said.
The primary culprit seems to be the Western Disturbances but there are other culprits too, the warming of Tibetan plateau is one of them, she added.
The report also highlighted the need for urgent reforms in the agrarian sector, given the expected increase in the frequency of extreme weather events, and cites instances of advancements in crop damage assessment and crop insurance schemes that are more attractive to farmers.
