Water Governance and International Co-operation: Lessons from the Cubango-Okavango River System

This policy briefing examines the Permanent Okavango River Basin Water Commission (OKACOM), a joint authority managing the Cubango-Okavango River System between Angola, Namibia, and Botswana. It analyzes the drivers of OKACOM's 20 years of successful cooperation and identifies future challenges, including climate change and asymmetrical economic benefits, while providing recommendations for sustainable trans-boundary water governance.

• The Permanent Okavango River Basin Water Commission (OKACOM) has successfully coordinated the national interests of Angola, Namibia, and Botswana for 20 years. This success is attributed to a strong legal and institutional framework, high levels of political trust and will based on historical alliances, and support from regional and international frameworks such as the UN Convention on Water and the Southern African Development Community’s Protocol for Shared Watercourses.
• Water abstraction from the Cubango-Okavango River Basin is dominated by Angola and Namibia. Angola has the highest level of abstraction at 53.1%, primarily for livestock and irrigation, and plans to develop two mini-hydropower stations by 2016. Namibia abstracts 42.5% of the system's water, relying on it as its only exploitable perennial river for agricultural irrigation. Botswana accounts for only 4.4% of total annual riparian abstractions.
• There is a significant asymmetrical distribution of economic benefits from the river basin. In 2008, the total gross national income of the basin was $234,085,700, with Botswana generating $177,317,500—largely from tourism in the Okavango Delta—while Namibia earned $43,204,500 and Angola earned $13,563,700.
• OKACOM utilizes several scientific tools to inform its Strategic Actions Programme (SAP), which guides the river basin's development for 20 years. These tools include the Transboundary Diagnostic Analysis (TDA), the Integrated Flow Assessment (IFA), and the Environmental Protection and Sustainable Management of the Okavango River Basin (EPSMO) project, all of which are reviewed every five years.
• The basin faces several critical threats to its sustainability, including population growth (projected to rise from 921,890 to over 1.28 million by 2025) and climate change, which may cause temperature increases between 2°C and 4°C and altered rainfall patterns. Future water demand is projected to increase by over 400 Mm3, and potentially up to 4,000 Mm3 in some scenarios.
• To sustain cooperation and prevent unilateral development that could damage the ecosystem, the document recommends that OKACOM implement an economic water accounting (EWA) mechanism and a 'Payment for Ecosystem Service' or financial benefit-sharing mechanism. This would provide incentives for upstream countries to avoid destructive developments and ensure a more equitable distribution of gains.
