This document is the accompanying case study volume to the WWDR-3. One of the overarching objectives of World Water Assessment Programme is to assist countries in enhancing their national capacity for water resources assessment by building on existing strengths and experiences. This mission has always constituted an integral part of the World Water Development Reports, which have included the findings of the case study development projects initiated in different geographic regions of the world. The case studies provide an in-depth analysis of the state of freshwater resources and related challenges that directly affect the livelihoods of people in the societies. Over the life of the programme to date, more than 64 countries have been covered at basin or national level. The increasing number of case studies necessitated the presentation of their findings separately. This first stand-alone volume of WWAP case studies, titled Facing the Challenges, includes 20 studies from Africa, Asia and the Pacific, Europe and Latin America, where conditions of water-related stress and socio-economic settings vary widely.
