This report provides information about the current “adaptation deficit” present in Uganda and the negative consequences and costs that climate variability already has on the Ugandan economy, and is 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 overall aim of this report 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 mobilise 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.
