Project Badweyn: Maritime Boundaries

In recent years, the Federal Government of Somalia has made significant progress toward defining its maritime boundaries. It first declared its territorial sea boundary out to 200 nautical miles (NM) in 1972. In 1989, Somalia ratified the United Nations Convention on the Law of the Sea (UNCLOS), which contains guidelines for claiming territorial waters out to 12 NM from shore and an exclusive economic zone (EEZ) out to 200 NM or the median line between two countries’ coastlines. Following civil unrest in the 1990s and 2000s, the Federal Government of Somalia officially declared its EEZ in 2014, continuing the process that began decades earlier. This claim was contested by Kenya and Yemen, with the southern border controversy reaching the International Court of Justice (ICJ). In October, 2021, the ICJ determined the line delimiting the maritime areas of both countries as shown in Project Badweyn. The objection to the Somali EEZ by Yemen is not yet resolved. 

In addition to declaring their EEZ in 2014, the Federal Government of Somalia extended their territorial waters from 12 to 24 NM in their revised Somali Fisheries Law to expand the area reserved for Somali fishers. The law states:

"The protection zone that protects coastal fishermen and in which fishing vessels are not permitted to enter is up to 24 nautical miles. Only coastal fishermen are allowed to fish within 24 nautical miles."

This protection of coastal fishing grounds is beneficial to communities that rely on fishing. Though it is clear that the nearshore areas are reserved for Somali fishers by federal law, foreign vessels are known to fish within the EEZ and even within territorial waters. The designation of boundaries does not prevent illegal, unreported, and unregulated (IUU) fishing, but it gives Somalis legal tools to combat IUU fishing and hold illicit vessels accountable for their actions. 

The confusion over who has access rights to fish within 24 NM from shore has resulted in competition for the fisheries in that zone. Clashes on the water between Somali artisanal fishers and foreign commercial fishers have resulted in conflicts including gear destruction and violence. A revised version of the federal fishing law that harmonizes the existing federal and state laws could go a long way toward alleviating this conflict.
