This study provides a quantitative assessment of the impacts of climate change onthe Namibian protected area system (PAS)to fulfil its mandate of conserving the country's biodiversity. The assessment looks at the PAS ability to achieve current protected area conservation targets as well as the ability of the current PAS to adequately conserve biodiversity given the anticipated future changes in the distribution of biodiversity due to climate change. Based on the assessment recommendations are made as to how to spatially adapt the PAS to better fulfil its mandate given the anticipated changes.
