Sustainable Water Management for Crop Production
JIRCAS international symposium series
The 20th century witnessed a tremendous growth in food production, especially from irrigated agriculture. Combination of hybrid varieties, agrochemicals and irrigation ensured global food security for billions. Scientists, policy-makers, extension workers and farmers involved in irrigated agriculture have plenty of reasons to be proud. In the 21st century, agriculture faces new challenges. While increasing population requires more food per capita, availability of land and water for irrigation is decreasing. More food has to be produced with less land and water. Despite the fact that agricultural researchers have obtained very high yields for crops at experimental sites, yields from farms remain low due to socio-economic, institutional, and technical reasons. This paper presents major socio-economic and institutional constraints faced by water managers in developing countries.
