Coastal & Marine Spatial Planning

Coastal and Marine Spatial Planning (CMSP) is a comprehensive, transparent, adaptive, and science-based process to analyze and allocate the spatial and temporal distribution of human activities in marine areas. Current and future ecological, economic, and social objectives identified through the planning process are addressed to reduce environmental impacts, align management decisions, facilitate compatible uses and reduce conflicts among users, among others. In practical terms, CMSP provides a public policy process for society to better determine how these areas are sustainably used and protected – now and for future generations. Successful management of the marine environment needs to be based on the best available science and will require continual information gathering to establish baselines, monitor ecosystems, and evaluate the efficacy of marine spatial plans.
