Rainfed agro-ecosystems occupy a significant place in Indian agriculture which is a source of
millions of small holders. Out of 141 million ha of net sown area in the country, 80 million ha
area is rainfed and will remain same for a foreseeable future (Srinivasarao et al., 2013). The
impact of climate change and variability in the country on agricultural production is evident in
the recent years. Rainfall and its distribution vary widely among the various agro ecosystems
impacting the yields of crops. Droughts, floods, delayed onset of monsoons and prolonged dry
spells are the major climatic vulnerabilities resulting the severe yield loss and affecting the
sustainable livelihoods. Conservation of rainwater and its recycling is important for sustainable
crop production in rainfed condition. The rainwater can be conserved either by in-situ or exsitu
in natural or manmade structure for supplemental irrigation. Soil conservation is an
important way to protect the productive lands.
