In this context, policy-makers will be re- sponsible for selecting, among a wide range of possible adaptation measures, those which will produce most benefits compared to the means required for their implemen- tation. The Belgian National project “ADAPT” aims to develop an efficient decision sup- port tool for the integrated assessment of adaptation measures against climate change induced flooding. During the project, a suitable methodology will be developed and comprehensively tested with the selection and assessment of adaptation measures for reducing future flood risks in the two main Belgian river basins, the Meuse and the Scheldt. As a first step of the ADAPT project, a synthesis of the knowledge and facts available concerning the effects of climate change in Belgium has been carried out. This synthe- sis provides a clear overview of the expected climate change impacts, their intensity, their variation, their uncertainty and their probable progression in time. The present contribution will focus on systematically describing those expected pri- mary impacts in Belgium. They include not only rises in temperatures and changes in precipitation, but also issues such as the occurrence and intensity of heat waves and droughts, rainfall and storms, as well as floods. Especially extreme weather events need to be considered. The analysis highlights that future evolutions of precipitation vary drastically between winter tim
