Water and energy linkages for groundwater exploitation: a case study of Gujarat State, India.
Water and energy, two important resources for human development, have inextricable interlinkages between them. Their complementarity, a blessing otherwise, causes a vicious cycle in a complex situation like the present case study of Gujarat State, India. This paper analyses the demand-supply situation of both sectors for a State that is primarily agrarian but also with a high industrial growth rate. Due to inequitable distribution of surface water, recurrent droughts and ever increasing demand trend, groundwater (a major source in the State) has been overexploited in many parts, leading to 'water mining' with worsening water quality. With more than 40% energy consumed for extracting groundwater, this has had a serious impact on the energy balance. The paper discusses the energy requirements to satisfy the water needs and the water requirements for generation of energy. Finally, the feasible options available to meet the crisis, ranging from development of mega projects like Sardar Sarovar and Kalpasar to micro water harvesting structures, water pricing, consumer training etc., are reviewed.
