Researchers and practitioners are developing several adaptation technologies (strategies) to address the climate change
impacts in agriculture. Observed rates of technology adoption range from 2 to 30% only in major river basins in India.
The estimated cost of uncertainty (in terms of profits foregone by the farmers) due to non-adoption of the technologies is high
compared to cost of technology itself thus justifying the need for technology promotion. At the farm level, lack of technical
skills/support and poor managerial ability of the farmers affect technology adoption compared to poor irrigation infrastructure
and inadequate water control at system level. This paper using the results of the optimization studies done during 2011-
12 in Godavari, Krishna, and Cauvery River Basins, India indicates that the future water scarcity and crop yield reductions
which range from 2 to 17% due to climate change could be managed through better adoption of the adaptation technologies.
Institutional support for timely supply of quality seeds, partial mechanization in rice transplanting and better training to
farmers on technologies using cluster approach could enhance the technology adoption and farmer income through better
management of the land and water in the river basins.
