This chapter restates the law that shapes maritime affairs in Namibia, focusing on its linkages to international law. Namibia has a long coastline, measuring 1,572 kilometres along the Atlantic Ocean. As a result of the Benguela Current wind-driven upwelling system, the country boasts one of the most productive fishing grounds in Africa. Namibia also offers a favourable environment for sea mining and shipping. Experts think that Namibia’s seabed is rich in minerals, for instance, copper, cobalt, manganese polymetallic nodules, and nickel. However, researchers and activists have highlighted the fact that marine mining damages biodiversity and conflicts with other economic activities, such as fisheries.By the time Namibia achieved independence from South Africa in 1990, several foreign fishing vessels were known to fish in Namibia's exclusive economic zone (EEZ) without a permit. The illegal fishing activities by foreign (mostly European) vessels led to litigation, which often touched on the law of the sea and certain other aspects of international law. Actually, the first international law cases that appeared before Namibian courts featured prominently this sort of illegal fishing.The literature on maritime law in Namibia and how it connects to international law has gathered dust: That literature dates as far back as the mid-1990s. Hence the necessity for a restatement of Namibia’s maritime law.Namibian marine law stems from several formal sources. The Constitution of Namibia, Acts of Parliament, international law, common law and case law. Statutes (for example, the Marine Traffic Act of 1981 and the Territorial Sea and Exclusive Economic Zones of Namibia Act of 1990) and ordinances (for example, the Sea-Shore Ordinance) govern this vast field of Namibia’s sophisticated legal system.This chapter states the law of the sea in Namibia through six sections. The first two sections specify which instruments and organizations Namibia has domesticated and currently participate in at the international and regional levels. The chapter then outlines the bilateral and trilateral instruments the country has signed. The next three sections identify and explain Namibia’s islands, baselines, and maritime zones (Section 4); maritime boundaries (Section 5); and the various uses that Namibia makes of its sea, for example, navigation, tourism, and spatial planning (Section 6).The sea is one of the pillars on which Namibia has built its economy, prosperity, society, and cultures. That said, it can be a force for both good and evil. Indeed, the sea represents one of the biggest sources of income for the government and yet it was also the scene for the ugliest corruption scandal of the country, as limelighted by the ongoing ‘Fishrot’ trial
