In Somalia, Fisheries are the backbone of the country's economy. In accordance with the African Union Agenda 2063, SDGs, and NDP plans, the Federal Government of Somalia launched several projects to enhance various marine ecosystems in Somali territorial waters. These initiatives were bolstered by the development of a new water resources strategy and a national environmental policy. Accordingly, this study's primary goal is to determine how the water policy, environmental policy and maritime code/law address pollution on the Mogadishu coast. Therefore, during 2019, three different locations were selected for Mogadishu City. During the winter and summer, a total of 12 water and sediment samples were collected, and their physical, chemical, and biological characteristics were studied. Moreover, about 191 samples from different stakeholders in the marine environment were selected randomly and responded to the questionnaires. According to the findings, external pollutants were the primary cause of water pollution (65%) from foreign ships. Chemical parameters (44%) caused the most pollution in the selected locations, followed by biological parameters (42%). According to the findings of this study, the majority of the selected areas had levels that exceeded the acceptable and recommended standards of WHO and EPA.
