Assessment of impact of climate change on water energy nexus in agriculture under canal irrigation system(2009-2012): Component - 1 The ICAR as the catalysing agent for the management of change in the Indian NARS

The main objective of the study is to assess the impact of climate change on water-energy nexus in agriculture under canal irrigation system. This project deals with six components designed to utilize the expertise available with the three consortium partners (INRM Consultants, New Delhi; IIM, Ahmedabad; CSWCRTI, Dehradun). The components are:

Water balance assessment - Baseline and Climate Change scenarios
Existing water demands - Baseline
Future water demands - Climate Change scenarios
Economic impact assessment
Integrate water and energy implications for Indian agriculture - Baseline and Climate Change scenarios
Policy implications of energy-water nexus for canal irrigation systems under changing climate scenario
The study is aimed to provide a holistic view to agriculture-water-climate change and energy nexus in the context of two canal irrigation systems, namely Sarda Sahayak Canal System and Sardar Sarovar Canal System (Main canal). Such integrated study provides policy insights for irrigated agriculture systems. It is an innovative attempt to use a soft-link approach between climate models, hydrology models and economic-energy-environment models to integrate agriculture-water-energy and climate change in the context of a canal irrigation system. A framework to capture water supply and demand (agriculture, residential, industry, energy and environmental flows) in the command and catchment areas of two canal irrigation systems is constructed which is required to assess the implications of climate change on these demands. Future scenarios to articulate policy implications for water-agriculture-energy-climate change nexus is attempted.
