The paper tackles the consequences of climate change impacts on fisheries and their dependent communities. It analyses the exposure, sensitivity and vulnerability of fisheries to climate change and presents examples of adaptive mechanisms currently used in the sector. The contribution of fisheries to greenhouse gas emissions is addressed and examples of mitigation strategies are given. The role of public policy and institutions in promoting climate change adaptation and mitigation is also explored.
This report provides a synthesis of key findings of sector studies undertaken in Vietnam in the context of the Economics of Adaptation to Climate Change (EACC) study. Sectors studied include agriculture, forestry, coastal port and aquaculture. Aquaculture, especially in the Mekong River Delta, is an important source of employment and rural income. The main impacts of climate change on aquaculture seem likely to be a consequence of increased flooding and salinity.
Compensatory mechanisms of the Peruvian hake population (Merluccius gayi peruanus) in response to heavy exploitation and changes in species interaction are discussed. Changes in the rate of cannibalism, diet composition, maximization of fecundity and behavioral adaptation are noted.
The FAO/WorldFish Center Workshop on Adapting to Climate Change: the Ecosystem Approach to Fisheries and Aquaculture in the Near East and North Africa took place in November, 2009 to identify and address the impacts created by climate change in the region, and how the Ecosystem Approach to Fisheries (EAF) and Aquaculture (EAA) can be utilized for the management and adaptation of fisheries and aquaculture in the face of these impacts.
The river floodplain ecosystems of the Sahelian region have recently undergone two major hydrological changes: (i) increased interannual variation in rainfall and (ii) a steep reduction of flood peaks and floodplain inundation following the construction of a number of dams and increased water abstraction. Fishers have little freedom of movement within the delta to help them cope with environmental changes. The only new opportunities are those offered by new reservoirs.
Anthropogenic global warming has significantly influenced physical and biological processes at global and regional scales. The observed and anticipated changes in global climate present significant opportunities and challenges for societies and economies. We compare the vulnerability of 132 national economies to potential climate change impacts on their capture fisheries using an indicator-based approach. Countries in Central and Western Africa (e.g.
Some of the most important inland fisheries in the World are found in semi-arid regions. Production systems and livelihoods in arid and semi-arid areas are at risk from future climate variability and change; their fisheries are no exception. This paper reviews the importance of fisheries to livelihoods in ‘wetlands in drylands’, with a focus on case-studies in Africa. We examine the threats posed by climate change to the traditional ‘tri-economy’ of fishing, farming and livestock herding.
Although as of June 1, 2020, Solomon Islands had no coronavirus cases, there was a national economic recession plus restrictions on people’s movement, gatherings, education and business activities. For rural areas, two of the biggest changes have been increased circulation of people—those who moved out of Honiara and back to the provinces—and reduced cash flow. Food trade is impacted by a lack of cash in circulation, meaning reduced marketing of foods in villages and a rise in bartering of fish for other foods.
WorldFish is pleased to welcome Dr. Cristina Rumbaitis del Rio to its Board of Trustees. She joins Director General Gareth Johnstone, Board Chair Yvonne Pinto and six other members in providing strategic direction and effective governance and leadership of the organization.
