Rainfall and soil water are fundamental parts of all terrestrial and aquatic ecosystems which supplies goods and services for human well-being. Availability and quality of water determines ecosystem productivity, both for agricultural and natural systems. There is increasing demand on water resources for development whilst maintaining healthy ecosystems, which put water resources under pressure. Ecosystem services suffer when rain and soil water becomes scarce due to changes from wet to dry seasons, or during within-seasonal droughts. Climate change, demand for development and already deteriorating state of ecosystems add to these pressures so that future challenges to sustain our ecosystems are escalating.
