Book (stand-alone)GESAMP - Assessment and communication of environmental risks in coastal aquaculture. 2008
Also available in:
No results found.This GESAMP study focuses on environmental risk assessment and communication in coastal aquaculture. To support effectively an open and transparent approach to sustainable resource use, risk assessment and communication must be able to fit within a broader social, economic and environmental decision-making framework. The communication aspects become paramount in enabling sustainable development in that type of decision-making environment. This publication presents a set of objectives, goals, met hodologies and a checklist for assessment and communication of environmental risks which may be associated with coastal aquaculture. It is structured to improve risk communication and to ensure that risk assessment is a scientific exercise in predicting environmental change. A set of six case studies is also presented to illustrate the use of the environmental risk assessment methodologies in coastal aquaculture. These examples of environmental interactions span a range of cultured species from fin fish to molluscs and shrimp. The type of effects studied includes effects on carrying capacity, phytoplankton, kelp, benthic fauna, the genome of wild fishes and salinisation of soils. -
Book (stand-alone)Reducing environmental impacts of coastal aquaculture. 1991
Also available in:
No results found.There have been substantial socio-economic benefits arising from the expansion of coastal aquaculture. However, in some coastal regions, this has caused significant ecological changes. 2. The type and scale of any ecological change associated with coastal aquaculture development will depend on the method of aquaculture, the level of production and the physical, chemical, and biological characteristics of the coastal area. Ecological change has been associated with the large-scale production of bivalves and seaweeds and the release of dissolved and particulate waste from fish, shrimp, and bivalve culture. Destruction of productive wetland habitats has resulted in the disturbance of wildlife and uncontrolled introductions and transfers have altered or impoverished the biodiversity of the receiving ecosystem. Some ecological change, such as the impact of organic waste on the seabed ecosystem, can limit production. 3. The indiscriminate use of bioactive compounds, including pesticides and antibiotics, has caused concern about their release into the aquatic environment. The health implications of the use of chemicals and the consumption of seafood grown in contaminated waters are problems of growing concern, especially in relation to intoxication by phycotoxins and infectious diseases such as typhoid fever, cholera, and hepatitis. 4. Some of the ecological and socio-economic problems encountered are due to the market failure to reflect the true cost of resource depletion and environmental change. The solution to this problem requires policy intervention at national and local level, particularly in regard to the issues of common property rights and economic incentives and deterrents needed to minimize environmental change. 5. Sustainable coastal aquaculture requires adequate consideration of the interactions among the social, economic and ecological changes. -

Also available in:
No results found.This Regional Study and Workshop on the Environmental Assessment and Management of Aquaculture Development (TCP/RAS/2253) was requested by governments of the Network of Aquaculture Centres in Asia-Pacific (NACA) and funded through the Tenchnical Co-operation Programme of the Food and Agriculture Organization of the United Nations (FAO). The project was launched in September 1992, with a planning meeting in Bangkok attended by National Environment Co-ordinators (NECs) nominated by participating g overnments. Following this planning meeting, the NECs undertook detailed country studies in preparation for the final workshop, held on 21–26 February 1994, at the Regional Office for Asia and the Pacific (RAPA) of FAO. The final workshop was attended by 30 government officers from 16 countries in the region, as well as 40 other participants that included representatives of various international organisations, international and regional resource speakers, members of the TCP project team (an ec onomist, environmental management specialist and legal expert) and observers from government agencies, non-government organisations and the private sector. The governments represented by their respective NECs and senior government planners included: Bangladesh; Cambodia; China; Hong Kong; India; Indonesia; Iran; Korea (Rep.); Lao PDR; Malaysia; Myanmar; Nepal; the Philippines; Sri Lanka; Thailand; and Vietnam. The NEC of Pakistan prepared a country report which was considered by the workshop. DP R Korea had participated in the planning meeting, but did not attend the final workshop. Participating international organisations included the World Health Organization (WHO), World Wide Fund for Nature (WWF) and United Nations Development Programme (UNDP).
