This study investigates the economic and environmental impacts of coastal land reclamation in Namibia. Utilizing a qualitative research approach, the study draws upon desk surveys and content analysis of existing literature, reports, and news items. Key documents, including both gray literature and academic sources, were rigorously sourced and analyzed using the SALSA (Search, Appraisal, Synthesis, and Analysis) framework to ensure comprehensive and methodical coverage. The results reveal that coastal land reclamation in Namibia has significant economic benefits, including enhanced port infrastructure, increased tourism potential, and opportunities for sustainable fisheries and aquaculture. However, these activities also pose substantial environmental risks, such as habitat destruction, pollution, and biodiversity loss. The construction of ports and oil developments, while economically beneficial, threaten marine ecosystems and the tourism industry that relies on them. The study highlights the importance of balancing economic development with environmental preservation through effective marine spatial planning. Practical implications include the need for stringent regulatory frameworks and incentives to promote sustainable practices. Policy-related implications emphasize the integration of stakeholder engagement in decision-making processes to ensure that economic benefits do not come at the expense of environmental health. The findings underscore the necessity for Namibia to adopt a holistic approach in its blue economy strategy, leveraging marine spatial planning to achieve sustainable development goals.
