A STITCH IN TIME: PREVENTIVE DIPLOMACY AND THE LAKE MALAWI DISPUTE

This policy brief examines the border dispute between Malawi and Tanzania over Lake Malawi, which escalated due to the discovery of potential oil reserves. It analyzes the failures of regional preventive diplomacy mechanisms, specifically within SADC and the AU, and argues for the empowerment of these institutions to resolve inter-state conflicts through legitimate, binding processes.

• The border dispute between Malawi and Tanzania, which dates back to at least May 1967, intensified in 2012 following the discovery of potential oil reserves along the northern border of Lake Malawi. The prospect of oil is described as a "significant game changer" because both nations are least developed countries facing severe socio-economic challenges, and Malawi specifically views these reserves as a "panacea to overcome these developmental challenges."
• The legal ambiguity of the border stems from the 1890 Anglo-German Agreement (Heligoland Treaty), which places the border on the Tanzanian shoreline. This contradicts the international law convention that transboundary fresh water borders typically lie in the middle of the body of water. There is significant regional concern that abrogating this treaty could destabilize other borders, as the integrity of colonial borders has been considered "sacrosanct" since the O own OAU was established on 25 May 1963.
• The disbandment of the SADC Tribunal has left a critical void in the region's ability to resolve inter-state disputes. While the tribunal was reinstated in 2014 with reduced powers, its full operation depends on a lengthy ratification process by SADC countries. The author argues that the loss of this institution removed a forum that could have provided a legal solution with the "political legitimacy necessary to ensure compliance by both parties."
• In the absence of the SADC Tribunal, the dispute was referred to the Africa Forum (Forum for Former African Heads of State and Government), led by Joaquim Chissano and Thabo Mbeki. However, this process is viewed as a "stopgap measure" and has faced challenges including inadequate resourcing and a lack of transparency, with very little public information available about its progress.
• SADC has attempted to establish a 'Mediation, Conflict Prevention and Preventive Diplomacy' architecture consisting of a panel of elders, a mediation reference group, and a mediation support unit. However, implementation has been slow, with the constitutive meeting for the reference group only occurring on 7 May 2015, reflecting a lack of political will and funding.
• The African Union's (AU) Continental Early Warning System (CEWS) and the AU Border Programme (AUBP) are tasked with border demarcation. While the AUBP is funded by the German agency GIZ, it is not equipped to handle active conflicts over demarcation. Consequently, the Lake Malawi/Nyasa dispute has remained off its agenda because such "politically charged" issues are believed to require political solutions between governments.
