Work flow between Step 1 (data collection and comparative analysis) and Step 2 (modelling).<\/p><\/div>\n

Plymouth Marine Laboratory (PML) will be conducting a comparative analysis on the importance of fisheries for food security in the three deltas\/regions: Volta (Ghana), Mahanadi (India) and Ganges-Brahmaputra-Meghna (Bangladesh) and how climate change could potentially influence marine ecosystems productivity. Deltas communities are strongly dependent on coastal fisheries including shallow wetlands and other semi-enclosed bodies of water. In these three countries fishery is a very important sector and contributes between 4-5% of Gross Domestic Product (GDP). Despite its importance for the local economy there are marked differences amongst countries, for example, the average per capita consumption (per year) of fish products varies with Ghana consuming the highest amount (25kg) followed by Bangladesh (14kg) and India (8.2kg). Delta communities are ranked amongst the poorest in the world and as a consequence potential impacts of global and regional climate change on the marine ecosystem productivity could have dramatic impacts on their economy and food security.<\/p>\n

For the DECCMA project data will be collected from available database and literature to give information about fisheries (e.g. commercial species, time series data of catches, fishing and natural mortality, division between subsistence, artisanal and commercial fisheries) and socio-economic structure (e.g. number of fishermen, type of vessels, incomes\/trades, consumption, livelihoods) in Ghana, Bangladesh and India. This part of the work will be conducted in liaison with local partners who will supply PML with local data whenever possible. This information will be summarised for the project report(s) and in published paper(s). The data collected and the information gained from the comparative analysis will support ecosystem modelling also carried out by PML. A model of water circulation and energy transfer (Proudman Oceanographic Laboratory Coastal Ocean Modelling System – POLCOMS) will be coupled with a model of the low trophic levels (the European Regional Seas Ecosystem Model – ERSEM) and fisheries models (size-spectrum and species based). The output from this framework will be fish production potential under climate change scenarios across the three delta\/regions. Finally these results will inform other work packages in the DECCMA project (migration, integration, economics and adaptation).<\/p>\n","protected":false},"excerpt":{"rendered":"
