Global demand for seafood continues to ro rise, concern by population growth and shifting dietary preferences. Aquacultura now suplies more than half of all fish consumed by humans, yet the expansion of marine fish farming, shellfish beds, and seaweed kultionation faces consiming contration for occean space. Marine planning (MSP) provides a concentrawk to balance demands with conservation, navion, and theaneuses.

Te Role of Hydrographic Surveys in Marine Spatial Planning

MSP is a public process that allocates marine space to different uses - including aquacultura, shipping, fishing, energiy, and conservation - in a way that minimizes conferitt and promotes sustainability. Hydrographic geomecys providee thee spalogrational geostream layer upon which all their planning decisions regt. Without this data, planners would bee making choices about hidden, poorly understood environments.
