About Orasecom

The Orange–Senqu River Commission – ORASECOM – was established by the governments of Botswana, Lesotho, Namibia and South Africa to promote equitable and sustainable development of the resources of the Orange–Senqu River. The Orange-Senqu drains one of the largest river basins in southern Africa covering an area of approximately one million square kilometres.

ORASECOM provides a forum for consultation and coordination between the basin states to promote integrated water resources management (IWRM). The IWRM approach helps to manage and develop water resources in a sustainable and balanced way, taking into account social, economic and environmental interests.

Such an approach requires the standardised collection, analysis and dissemination of information on all aspects of the basin, a policy that is in accordance with the ‘ORASECOM Agreement’ and SADC protocols.

This Water Information System – WIS – provides the tool for sharing and managing data and information on the Orange–Senqu River basin.
