In Zimbabwe, trends in economic growth have been linked to rainfall variability, which can be attributed to sensitivity in the agricultural sector. Improved water resources management is critical to the stability and security that is required for economic development. The recent decline in growth can be caused by other factors such as land reform policies (starting in 2000).

For Sub-Saharan Africa, patterns in economic growth follow precipitation patterns closely. As rainfall has decreased over the last 30 years, so has the financial development. Rainfed agriculture represents a major share of the economy of these countries, as well as for domestic food supply. Improved water resources management and a wider resource base are critical to the stability and security that is required for economic development.
