This chapter provides an overview of the composition and distribution of the country’s water resources across the river basins and regions (oblasts) of Belarus. It presents the effects of climate change and other anthropogenic pressures on the quantity, quality and seasonal availability of water resources as well as the progress Belarus has made over time towards a less water-intensive economy. It includes four case studies displaying the diversity of challenges facing different oblasts in Belarus with varying endowments of water resources and demographic trends and pressures. The chapter also describes the policy instruments and legal, regulatory and institutional frameworks that form the country’s water resource management system. On the subject of monitoring surface and groundwater, the chapter presents concrete examples of how the process of delineating water bodies and monitoring water quality has taken place in Belarus through the European Union Water Initiative Plus project.
