South Africa is a water-scarce country with an average rainfall of 500 mm per year. It is estimated that national water … demand will exceed supply by 2025. Increasing the water supply would be environmentally, financially or politically … unfeasible. Impoverished communities, especially those in rural areas, require access to water for drinking, cooking and other …

Water and agriculture are intrinsically linked. Water is essential for crop production and agriculture is the largest … consumer of freshwater resources. However, this link is commonly ignored by economic models mainly because water use is not … reported in the national economic accounts. Few regions have markets for water.
