Can Spatial Planning in Aquaculture Contribute to Conservation?
Spatial planning can help ensure aquaculture development supports food production, biodiversity conservation and ecosystem restoration, according to the Food and Agriculture Organization of the United Nations (FAO). The FAO Guidelines for Sustainable Aquaculture call for balancing economic, social and environmental objectives when selecting sites for coastal and offshore farms.
Studies of biodiversity, water quality, climate and socio-economic factors, alongside stakeholder engagement and environmental impact assessments, are essential first steps. Strategic siting of seaweed, shellfish and offshore cage farms can improve water quality, reduce waste and protect marine ecosystems while maintaining productivity and profitability.
