Marine Spatial Planning (MSP) and Blue Economic Development are crucial for Malaysia’s sustainable use of its marine resources. MSP involves organizing the use of marine spaces to balance ecological, economic, and social objectives, ensuring the health of ocean ecosystems. Blue Economic Development focuses on sustainable economic growth from marine and coastal activities, such as fisheries, tourism, and renewable energy. Together, these strategies help Malaysia protect its rich marine biodiversity while promoting sustainable development and economic opportunities for coastal communities.
