The National workshop for the finalization of the sensitivity mapping Project took place at the Protea Walvis Bay Hotel, in Walvis Bay, Namibia, from the 11 March to the 13 March 2013. The National workshop was organised by the Ministry of Works and Transport, Government of Namibia and supported by the International Maritime Organization (IMO), and IPIECA, The global oil and gas industry association for environmental and social issues, within the GI WACAF Project framework. The workshop drew 32 participants from the IMO; national authorities, the private sector, and Non-Governmental Organizations. In a context of increasing risks of oil pollution coming from shipping and oil exploration activities along the Namibian coast, the participants acknowledged the need to develop a fully operational National Contingency Plan, including all necessary information such as sensitivity maps, in order tornallow the development of response strategies and their effective implementation. During the plenary session, the participants were reminded about the IPIECA methodology detailed in the IPIECA Guidelines on sensitivity mapping with an emphasis on the key elements to be included for each type of maps (sensitivity, tactical and operational maps). On the basis of the data developed during the last GI WACAF Workshop organised in Decemberrn2010, three working groups carried out the identification of the most sensitive sites for each type of map, using a Geographic Information System (GIS). The produced data was then validated during the plenary session.
