This report which mainly discusses The Economic Assessment of the Impacts of Climate Change, presents information about the current “adaptation deficit” in Uganda and the negative consequences and costs that climate variability already has on the Ugandan economy and expected to have under future climate change scenarios. Economic assessments of the impacts of climate change were conducted at the national level for five sectors (agriculture and livestock, energy, water, human settlements, and transport infrastructure) and detailed case studies were carried out in five local level locations: Kampala (focusing on infrastructure), Kabale & Tororo (health), Karamoja (agriculture and livestock), Mount Elgon (coffee), and Mpanga river catchment (water and electricity). The national-level assessment was carried out under two of the latest Representative Concentration Pathways (RCPs) developed as part of the Fifth Assessment Report (AR5) under the Intergovernmental Panel on Climate Change (IPCC). The overall aim is to provide policy makers and international development partners in Uganda with the evidence base on the economic impacts of climate change in order to mobilize increased investment for adaptation in climate-sensitive sectors. The study also aims to increase the capacity of government officials to use the evidence on the economic impacts of climate change in development and investment planning.
