Water scarcity is not a new concept, nor a new phenomenon. History provides us with many examples of cities and countries facing challenges to securing stable and reliable fresh water supplies.
However, current trends challenge water managers and decision makers in new ways - from progressive depletion and deterioration of water resources to drastic changes in hydrology due to climate change. In fact, water practitioners recently gathered in Brasilia, Brazil for the World Water Forum and World Water Day 2018 to discuss the world’s most pressing water issues. Recent crises in Cape Town, South Africa and Rome, Italy provided a backdrop and served as a reminder of the urgency with which water resilience is needed.
Despite such concerning events, water demands are skyrocketing as cities expand, draining already scarce resources -- and water scarce cities are edging closer and closer to running dry. And, although a number of water scarce cities are actually beating the odds, their stories often remain undocumented, unavailable, and inaccessible.
A new World Bank report illuminates such valuable experiences to fill this important knowledge gap about the failures, successes, and innovative solutions of water scarce cities across the world. The report provides a cross-case analysis that dives into knowledge from over 20 case studies (to be published soon), to compare and contrast water resource challenges, technical solutions, and institutional mechanisms. In so doing, the report creates new knowledge and identifies the key drivers of positive change -- including how governance, capacity, or technological changes were addressed.
