dc.description.abstract | Globally rainfed agriculture is very important as 80% of the world’s agricultural land area is rainfed and generates 58% of the world’s staple foods (SIWI 2001). Most food for poor communities in the developing countries is produced in rainfed areas; for example, in sub-Saharan Africa (SSA) more than 95% of the farm land is rainfed, while the corresponding figure for Latin America is almost 90%, for South Asia about 60%, for East Asia 65%, and for Near East and North Africa 75%. In India, 66% of 142 million ha arable land is rainfed. Rainfed agriculture in regions characterized by erratic rainfall is subject to large inherent water related risks, which make farmers less likely to invest in production enhancing inputs. If these risks can be lowered through investments in water management techniques to bridge dry spells, farmers’ attitude regarding agricultural investments might also change. In rainfed areas, rainfall is the most prominent random parameter beyond farmers’ control. Hence, rainfall is both a critical input and a primary source of risk and uncertainty for agricultural production (Rockström et al., 2009). The Comprehensive Assessment of Water Management in Agriculture (Molden et al., 2007) also points out to a large, untapped potential for upgrading rainfed agriculture and calls for increased investments in the sector. On-farm water balance analysis indicates that in semi-arid parts of India only 30–45% of rainfall is used for crop production in the traditional management systems (Wani et al., 2003b). In SSA, less than 30% of rainfall is used as productive transpiration by crops. On severely degraded land, this proportion can be as small as 5% (Rockström and Steiner 2003). Thus, crop failures commonly blamed on “drought’’ might be prevented in many cases through better farm-level water management. Current irrigation water withdrawals are already causing stress in many of the world’s major river basins (Molle et al., 2007). The world is facing a water crisis with little scope for further expansion of large-scale irrigation. Therefore, it is necessary to improve water management in rainfed agriculture not only to secure the water required for food production (Molden et al., 2007) but also to build resilience for coping with the future water related risks and uncertainties (Rockström et al., 2010). Some experts are predicting further decline in rainfall and amplification of extreme events (IPCC 2007). | en_US |
