Author Description

The quantity of available water and land has not increased since 1950, but the availability of water and land per capita has declined significantly due to an increased global human population. Global food security for this growing population requires careful management of water resources. In this chapter, we analyse the status of agricultural water use in tropical rain-fed areas, assess the potential for improvement and then propose a new paradigm to manage agricultural water efficiently by adopting various land, water, nutrient and crop management technologies.
