With three-quarters of Asia-Pacific countries currently facing water scarcity and the vast majority of the region’s river basins categorised as transboundary, water managers in the region need to manage water resources in a cooperative manner that promotes sustainable development. Numerous macro trends in the region make this challenging: rapid urbanisation and economic growth, and increased demand for energy and food along with the impacts of climate change. In Europe, the Danube River Basin also faces challenges to water quality and quantity. As Europe has developed a strategy to increase the river basin’s water quality and quantity, best practices and lessons learned regarding integrated water resources management in the Danube River Basin can be transferred to the Asia-Pacific region.
