As per the report Observed Rainfall Variability and Changes, seven states-- Uttar Pradesh, Bihar, West Bengal, Himachal Pradesh, Arunachal Pradesh, Meghalaya and Nagaland-- have shown significant decreasing trends in annual rainfall in the last 30 years and many parts of the country witnessed increase in number of dry days during the monsoon season which adversely affected groundwater recharges in these regions. The changing rainfall pattern is attributed to climate change and global warming. In its recommendations, the committee with whom the report was shared suggested a need to explore 'monetisation of data and information' through a well-thought out policy.
