  • Food security and reducing poverty for the ever-growing populationin India is a challenging task. India?s agricultural land is 142 millionha with 135% cropping intensity (NAAS, 2009) and 60% is rainfed,which is characterized by water scarcity, land degradation, low use ofinputs and low productivity. Agricultural productivity of these areasoscillates between 0.5 t/ha and 2 t/ha with an average of 1 t/ha (Rockstromet a l, 2010; Wani et al., 2011a, b). Of the total agricultural area, the40% that is irrigated land contributes 55% of total food productionin the country (Gol, 2012) but on the other hand it consumes almost70% of freshwater resources and has left limited scope for further expansionof the irrigated area (Central Water Commission, 2005; CGWB,2012). Thus, achieving food security of the country at present and inthe future is largely dependent on rainfed agriculture (Wani et al., 2009,2012a). Despite several constraints and limitations of rainfed areas,huge untapped potential exists for enhancing crop yield through improvedland, water, nutrient and other natural resource managementoptions (Rockstrom et al., 2007; Garg et al., 2012a, 2013; Wani et al.,2012a; Singh et al., 2014)
