Irrigation in India has become increasingly dependent on wells, with the consequent impacts on groundwater availability and on energy use for its extraction.  Efforts have been made over the past three decades – from local pilot projects, to state-wide programmes – towards improving the efficiency with which groundwater is pumped, and, for its re-charge and conservation.  In this report, we have compiled the information available, from published reports and papers as well as news bulletins, on the field activities and studies carried out with respect to efficient water extraction and use for agriculture.  Numerous programmes have been included – ranging from cases where a few pump sets were focused on, to large programmes addressing thousands of pump sets.  However, most of the cases involve the replacement/retrofitting of electrically-powered irrigation pump sets. 
This compilation has two purposes. Firstly, we are beginning a repository of such reports that is publicly accessible and can be expanded with more documents.  As importantly, we intend eliciting lessons from past experiences that would benefit future programmes, thereby improving irrigation efficiency and contributing to the conservation of energy and water.
