Review of environmental impact assessment and monitoring in aquaculture in Asia-Pacific

This review is prepared as part of the FAO Project “Environmental Impact Assessment (EIA) and monitoring in aquaculture”. The review provides a compilation, review and synthesis of existing EIA and environmental monitoring procedures and practices in aquaculture in the Asia-Pacific region, the largest aquaculture-producing region in the world. This review, as in other regions, gives special consideration to four areas related to EIA and monitoring in aquaculture including: (1) the requirements (2) the practice (3) the effectiveness and (4) suggestions for improvements.
