Climate Change Vulnerability Assessment in Mangrove regions of Sierra Leone Full Report January 2018 This work was conducted under the USAID-funded West Africa Biodiversity and Climate Change (WA BiCC) project. The report is an unabridged version of the official USAID report by the same name published as an Abridged Report in May 2017, and available at http://www.ciesin.columbia.edu/wa-bicc/wa-bicc-ccva-abridged-ff.pdf. The report was prepared by the Center for International Earth Science Information Network (CIESIN) of the Earth Institute of Columbia University. The vulnerability assessment was led by CIESIN under contract with Tetra Tech, and CIESIN also led the analysis and report development. In addition to the CIESIN lead researcher, Sylwia Trzaska, the field research was conducted by a team comprised of representatives from the WA BiCC technical unit in Freetown, Fourah Bay College, Njala University, the National Protected Areas Authority (NPAA), Environmental Protection Agency (EPA), the Ministry of Agriculture, Forestry and Food Security, the Ministry of Lands, Country Planning and Environment, the Ministry of Fisheries and Marine Resources, Conservation Society of Sierra Leone and other stakeholders. The authors of the report are Sylwia Trzaska, Alex de Sherbinin, Paola Kim-Blanco, Valentina Mara, Emilie Schnarr, Malanding Jaiteh, and Pinki Mondal at CIESIN. The team wishes to acknowledge the contributions of Zebedee Njisuh, Aiah Lebbie, Samuel Weekes, George Ganda and Michael Balinga. A full list of field research staff can be found in Annex 5 of this report. Without their hard work and dedication under challenging conditions, this vulnerability assessment would not have been possible.
