Development of an Inventory of Ecosystem Services in Namibia Final Report Namibia Nature Foundation In collaboration with: SAIEA, Sustainable Solutions Trust, Research and Information Services of Namibia and eftec 2016 Development of an Inventory of Ecosystem Services in Namibia Acknowledgements The authors would in particular like to thank Dr. Konrad Uebelhoer and Dr. Martin Nowack of GIZ, Ms. Ece Ozdemiroglu of eftec, Gillian Maggs-Kölling, Theo Wassenaar, John Irish (Gobabeb Training and Research Centre) and Mutjinde Katjiua (Namibia University of Science and Technology NUST) who reviewed and provided detailed comments to support the finalisation of the report. Ben Nathanael designed and compiled the maps of each ecosystem zone. This study was financed by the Resource Mobilisation Project of the Ministry of Environment and Tourism and the Deutsche Gesellschaft für international Zusammenarbeit (GIZ) GmbH. The Resource Mobilisation Project is part of the International Climate Initiative (IKI) of the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB). The BMUB supports this initiative on the basis of a decision adopted by the German Bundestag. Contributing Authors Lawrie Harper-Simmonds, Dr John Mendelsohn, Dr Jean-Paul Roux, John Pallet, Dr Chris Brown, Angus Middleton and Johannes Kruse Edited: Catherine Birch Updates This inventory of ecosystem services is a first step, and should lead to debate, research, and further iteration. As more knowledge and data are gathered and our understanding of ecosystem services is improved, this inventory can potentially be updated. To this purpose, contributions can be submitted to the email address below. Please note that only well-developed submissions backed up by data/evidence/qualified opinion will be considered.
