Water is perhaps South Africa's most critical resource - one of low abundance and growing needs. Tie that with problems of increased land use and population growth and you have several big reasons for concern. South Africa's freshwater supply is almost stretched to its limit. Less than 10% of South Africa’s rainfall is available as surface water, one of the lowest conversion ratios in the world. The country’s groundwater resources are equally limited. Despite regulations of river waters, in many catchments the need for water exceeds the supply and quality is often below standards. Given the projected growth in population and economic development, South Africa faces tough times in meeting water demands in the decades ahead.
