As of July 2025, Namibia has only one designated Marine Protected Area (MPA), the Namibian Islands' Marine Protected Area (NIMPA), located within an Ecologically or Biologically Significant Area (EBSA). Covering roughly 9,500km, or 1.7% of Namibia's Exclusive Economic Zone (EEZ), NIMPA plays a critical role in marine conservation. It is, for instance, home to most of Namibia's seabird colonies, making it a vital sanctuary for biodiversity. However, funding for its effective management remains inadequate due to competing national priorities. At the same time, NIMPA faces growing threats from overfishing, mining, marine pollution, large-scale mariculture, and the harvesting of live marine mammals. As Namibia's first and only designated MPA, establishing a sustainable financing model for NIMPA presents an opportunity not only to secure its future but also to serve as a blueprint for future MPAs, supporting Namibia's commitment to meeting Target 3 of the Kunming-Montreal Global Biodiversity Framework, which is to "Conserve 30% of Land, Waters and Seas". This policy brief outlines viable financing mechanisms for ensuring the long-term, effective management of NIMPA.
