Freshwater habitats such as lakes, rivers, streams, wetlands and aquifers house an incredible proportion of the world’s biodiversity: more than 10% of all known animals and about 50% of all known fish species. Yet despite the massive role water plays for people and nature, it is a surprisingly finite resource. Less than 1% of the world's water is fresh and accessible.
Zambia has extensive surface water resources, with a number of large perennial rivers and yet an estimated 4.8 million Zambians lack regular access to clean water and 6.6 million lack access to adequate sanitation facilities. Poor water and sanitation are a major factor in Zambia’s high rates of childhood malnutrition and mortality.
