The Natural Resources Institute (NRI) of the University of Greenwich is sub-contracted by the Impact Assessment Research Centre (IARC) of the University of Manchester to undertake a Sustainability Impact Assessment (SIA) of WTO Negotiations - Fisheries Sector Study. The study is funded by the European Commission in Brussels (DG Trade) and the current report reflects work undertaken during the second phase of the study. The overall objective of the study is to assess the potential economic, social and environmental impacts of trade measures arising from the Doha Development Agenda (DDA) negotiations that have an impact on fisheries production and trade. These trade measures include: market access (i.e. tariff and non-tariff measures) as part of the negotiations on non-agricultural market access (NAMA); subsidies to the fisheries sector in different forms, which are being discussed by the WTO Negotiating Group on Rules; and other trade issues, e.g. SPS and TBT issues and services incidental to fisheries
