Obligations to Protect and Preserve Marine Environment from Land-Based Sources of Pollution: A Case of the Indian Ocean in Tanzania

The 1982 United Nations Convention on the Law of the Sea (UNCLOS) regulates marine pollution from land-based sources worldwide. It provides a comprehensive framework for the development of regional conventions and national laws addressing marine pollution from land-based sources. UNCLOS is closely tied to human rights treaties, since the environment and human rights are interconnected. This study examines Tanzania’s legal system and its adherence to international and regional commitments to protect the maritime environment. Based on a review of relevant documents, the study finds that Tanzania’s regulatory framework largely aligns with international and regional conventions on marine pollution from land-based sources. However, the study concludes that environmental pollution caused by land-based sources remains a significant concern in the Indian Ocean in Tanzania. This may be attributed to factors such as unplanned settlements, limited institutional capacity for waste management, inadequate fines for environmental offenses, insufficient enforcement of environmental regulations, and restricted locus standi. By addressing these shortcomings, Tanzania can better fulfill its obligations under international agreements to improve environmental protection and promote sustainable development.
