This brochure is part of a series that collectively detail how a community-based assessment of climate change was used in partnership with coastal communities and provincial and national-level stakeholders in Timor-Leste and Solomon Islands. The assessment contains four distinct, but related, steps focused on supporting community-level decision-making for adaptation through a series of participatory action research activities. Each brochure in this series details a specific activity in the four-step assessment.
Biophysical impacts of aquaculture, with consequences for biodiversity, vary with species and culture systems and include issues such as: nutrient enrichment/removal, chemicals, land use, species introductions, genetic flow to wild populations, disturbance of balance or introduction of pathogen/parasites, consumption of capture fishery resources, energy, and greenhouse gas emissions. Guiding principles, labeling schemes and various tools are needed to analyze performance and conformance.
A poster on WorldFish Bangladesh, and its mission to reduce poverty and hunger by improving fisheries and aquaculture
During the period of May to July 2002, An Giang University, in conjunction with the Chau Phu, Thoai Son and Chau Doc District People's Committees, and Can Tho University conducted Participatory Rural Appraisals (PRAs) in four different Provinces. The research findings from this study are presented in this report. The purpose of this exercise was to better understand the livelihoods of people living in rural areas and depending mainly on inland capture fisheries.
This study was an attempt to apply land-based GIS analysis for freshwater aquaculture planning in the Red River Delta of Vietnam. It was based on diverse data sources in order to help decision makers at the site and also to contribute to the modelling of selection processes for aquaculture development planning in the region.
This document represents the report and contributed papers from the workshop Pioneering Fish Genetic Resource Management and Seed Dissemination Programmes for Africa: Adapting principles of selective breeding to the improvement of aquaculture in the Volta Basin, convened in Accra, Ghana 27-30 March 2007.
A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch per effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp recruitment decreased with decreasing egg production, but increased with decreasing total (mainly fish) standing stock. The net result of these counteracting effects was an overall increase in shrimp recruitment, attributable to a greatly reduced prerecruit mortality.
The Southwestern coastal zone of Bangladesh is agro-based and one of the world’s most populous, poverty-stricken and food-insecure regions, with high vulnerability to climate change. Shrimp aquaculture rapidly expanded in this tidal floodplain but shrimp is highly susceptible to disease, has less contribution in local consumption, and its profitability depends on international market prices, leading the demand for improving the farming system.
This article present a Bayesian probabilistic method to support out-scaling of technologies from pilot projects. The method is applied to aerobic rice, a water-saving technology with probable global potential. The method assumes that areas similar to pilot sites are more likely to adopt than those that are different or unfavourable. Similarity is defined from climate, landscape and socio-economic attributes. Favourability is further evaluated by project specialists. Scaling out is not a simple linear process, so the method is proposed as a complement to learning processes.
The Managing Aquatic Agricultural Systems to Improve Nutrition and Livelihoods in Rural Myanmar (MYNutrition) project intends to adapt and scale up the successful innovative integrated aquaculture and fisheries/agriculture-nutrition linkages developed under the IFAD-funded Small Fish and Nutrition project in northeast and northwest rural Bangladesh in 2010-2013.
