Water

The day-to-day variability of rainfall associated with weather is a major risk factor for rainfed agriculture. Climate change is already affecting the frequency and intensity of rainfalls. Climate change adaptation for agricultural cropping systems requires increased resilience to both excess water and lack of water.

A broad range of agricultural water management practices and technologies are available to spread and buffer production risks. Enhancing residual soil moisture through land conservation techniques assists significantly at the margin of dry periods while buffer strips, mulching and zero tillage help to mitigate soil erosion risk in areas where rainfall intensities increase.
