摘要：

Direct and indirect effects of climate change will have an adverse impact on water resources, human systems, regional agriculture, and food security. India, with a population of more than 1.2billion, has experienced tremendous economic growth in the last two decades with only 4% of the world's water resources and about 9% of the world's arable land. Rainfall is distributed highly unevenly in the spatio-temporal space, with the highest rainfall-receiving region on the planet in northeastern (NE) India, in contrast to Thar Desert in western India. There has been a significant change in precipitation and temperature during 2000-2015 in India in comparison to the last 100years. This could indicate a signature of climate change in India. We find that a comprehensive and detailed understanding and clear assessment of the impact of climate change on India's water resources are required to reach a definitive conclusion and explanation of the trends to better inform policy actions.
