Mangroves and seagrasses are of special interest to coastal fisheries worldwide because of the role they play in providing nursery areas for commonly harvested fish and invertebrates. Although the ecology of fish and invertebrates associated with mangroves and seagrasses in the tropical Pacific is not well understood compared with other parts of the world, the connectivity among mangroves, seagrasses, intertidal flats and coral reefs indicates that mangroves and seagrasses throughout the region provide a similar function to such habitats elsewhere.
In this chapter, the authors assess the vulnerability of aquaculture in the tropical Pacific to climate change. It begins by summarising recent and potential aquaculture production to set the scene for the sector, and then use the framework outlined in Chapter 1, based on exposure, sensitivity, potential impact and adaptive capacity, to evaluate the vulnerability of the main commodities for food security and livelihoods.
The commercial aquaculture feed industry in Egypt is growing at a rapid rate. As a result, the number of fish feed mills has increased from just 5 mills producing about 20,000 t per year in 1999, to over 60 mills with a current production estimate of 800,000–1,000,000 t/year. The performance of the aquafeed industry in Egypt is not well understood, as the value chain structure has not yet been mapped.
Egypt’s aquaculture production (705,490 tonnes in 2009) is by far the largest of any African country and places it 11th in terms of global production. The aquaculture sector makes a significant contribution to income, employment creation and food security in the country, all of which are national priority areas given low per capita income levels, rising population, worsening food security indicators, and official unemployment levels which have remained at around 10% for the last ten years.
This paper deals with a number of case studies that were undertaken during the last 8- 10 years in utilizing divergent ‘Tal’ wetland ecosystems (deep, semi-deep, temporary in a range of agro-ecological zones like NAZ, OAZ and Coastal Zone of the region) for the development of integrated management programmes using a range of approaches.
Resilience is emerging as a promising vehicle for improving management of social-ecological systems that can potentially lead to more sustainable arrangements between environmental and social spheres. Central to an understanding of how to support resilience is the need to understand social change and its links with adaptation and transformation. Our aim is to contribute to insights about and understanding of underlying social dynamics at play in social-ecological systems.
While an overwhelming majority of sub-Saharan African countries exhibit serious weaknesses in statistics pertaining to crop and livestock sectors, the deficiencies in terms of nationallyrepresentative data on the fishery sector are even more acute. The very little data available on the sector are essentially derived from case studies of selected fisheries, and the limited nationally representative data available are generally derived from a few questions included in the livestock section of household surveys.
The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is committed to improving the food security and wellbeing of poor people who depend on freshwater and coastal ecosystems for their livelihoods. AAS is particularly concerned with enhancing the equity of the social, economic and political structures that influence the livelihoods of poor households dependent on aquatic agricultural systems.
Due to inadequate technical knowledge and training in advanced methods of gradually growing tilapia culture, framers are not getting expected yield. From the very beginning of the CSISA-BD project, WoldFish Center has taken initiative to introduce advanced methods in tilapia culture. To do this, the shortage of skilled trainers and training materials, has, particularly, been realized. Presently, a number of manuals on tilapia culture from Department of Fisheries, Bangladesh Fisheries Research Institute, WorldFish Center and different GOs and NGOs are available.
A description is given of the Japanese muro-ami fishing gear, which although is very effective in catching elusivereef fish, causes considerable reef damage during its operation.
