Aquaculture is one of the fastest growing food production sectors in the world and an attractive option for improving livelihood security, especially in developing countries. Yet as aquaculture assumes greater significance as a means to meet global food and nutrition demands, concerns about the environmental impacts of aquaculture systems are on the rise.
Indonesia is the world's second largest seafood producer, but capture fisheries landings have slowed down over the last decade. In response, the Indonesian government has also set ambitious targets for expanding the aquaculture sector up to 2030. The present research therefore quantifies environmental impacts using life cycle assessments (LCAs), and some socioeconomic indicators, for six alternative scenarios projecting the growth of Indonesia's aquaculture up to 2030 by Tran et al. (2017).
There are increasing requirements for impact assessment by development partners in order to increase the accountability and effectiveness of research and development projects. Impact assessment research has been dominated by conventional economic methods. This context challenges agricultural research organizations to develop and apply alternative impact assessment methods incorporating economic, social, and environmental impact components.
Asia is the leading aquaculture region in the world, contributing to 85% of total world aquaculture production. Of the top 10 aquaculture producing countries 9 are Asian with China accounting for more than 65% of Asian production. Aquaculture in Asia contribute more than 80% of an estimated 17-20 million aquaculture farmers in Asia providing livelihoods, food security and export earning power but at the same time there are growing problems with environmental impact from large numbers of small-scale producers and the difficulties in planning and management of further development.
This paper presents an evaluation of the 15-week course on Training in Fisheries Planning and Management being offered at the University of Namibia since 1991. This course includes instruction in fisheries technology, fisheries biology, fisheries law and law of the sea, fisheries economics, fisheries sociology, environment impact assessment, planning and management, the logical framework approach to planning and computer literacy. The participats in the course have rated the various elements in a range of 2.9 to 4.7 out of a maximum of 5 points.
Introductions of exotic finfish between 1948 and 1953 are reported in this paper, with a brief reference to earlier and later introductions. Exotic fish were introduced principally to develop the potential for aquaculture in fresh and brackish waters in order to increase the availability of fish for rural communities through the biological control of aquatic vegetation. The algal feeding tilapia (Sarotherodon mossambicus) has created a new food industry in inland and brackishwaters.
This report documents the results from an assessment of the influence of built structures on the livelihoods of Tonle Sap communities, as part of the livelihoods component of the “Study of the Influence of Built Structures on the Fisheries of the Tonle Sap”.
Aquaculture, like all interventions by humans to exploit or manage natural resources for food production, has the potential for causing environmental harm as well as for improving livelihood and nutrition. Aquaculture development must be undertaken in a broad intersectoral context, considering especially its interactions with agriculture, forestry and capture fisheries and its environmental consequences.
The diversity and abundance of benthic organisms were examined in relation to logging impacts in Western Province, Solomon Islands. Organisms occupying sediments offshore from the mouths of logged and unlogged streams in two areas were sampled at three depths during a single survey. Overall abundances of organisms were low, and patterns varied between areas.
