Improving Water Productivity and Efficiency

Date Published:

Rainfall variability has adverse impacts on agriculture production. Rainfall variability experienced in sub-Saharan Africa already has detrimental impacts on crop production. Indeed, too much or too little water due to erratic rainfall and insufficient storage capacity wields adverse impacts on food security. Climate change is widely predicted to increase rainfall variability in sub-Saharan Africa, with the effect of increasing droughts and floods. For many millions of smallholder farmers, reliable access to water is the difference between plenty and famine. It is therefore essential to find ways to cope with existing and increasing variability in rainfall, as well as other effects of climate change like changes in temperature patterns.

This factsheet was developed as part of the Comprehensive Africa Agriculture Development Programme (CAADP) Climate-Smart Agriculture Workshop. The workshop focused on approaches for effective program design of climate-smart agriculture in support of both country and regional CAADP investment plans. Climate-smart agriculture incorporates practices that increase productivity, efficiency, resilience, adaptive capacity, and mitigation potential of production systems.
