In Uganda alone, the use of inland water resources is worth almost USD 300 million a year in terms of forest catchment protection, erosion control and water purification services. Almost 1 million urban dwellers rely on natural wetlands for wastewater retention and purification services.

That is USD 16 million in terms of groundwater recharge, USD 45 million in terms of water purification and treatment services and USD 3 million in reducing flood-related damage costs.
