In times of international agreements and efforts to mitigate climate change and meet sustainable development, water deserves special attention due to its importance to human and environmental sustenance. Fresh water accounts for a significant small share of water resources and is the base for human activities, encompassing drinking, irrigation, as well as industrial use. The use of freshwater involves challenges regarding poverty, malnutrition, governance, and sustainable management of natural resources. As water and population are unevenly distributed across the globe, some regions are to bear higher impacts as water falls short. It is estimated that almost one quarter of the global population lacks water for basic needs; however, climate change, population and economic growth, and the increasing demand of water-intensive goods alarm higher levels of water scarcity. Concerns over sustainable alternatives for water management are gaining momentum as water conflicts have trespassed to the 21st century as a prevailing matter. Following from the UN Sustainable Development Goals the "Virtual Water Values – Multi-scale Monitoring of Global Water Resources and Options for an Efficient and Sustainable Use” (ViWA) project is a transdisciplinary initiative to produce high quality research to meet sustainable and efficient use of global water resources. ViWA is a collaborative project of the funding program "Global Resource Water (GROW)" in the framework program FONA (Research for Sustainability) of the German Ministry for Education and Research (BMBF). ViWA further develops the Computable General Equilibrium model DART-WATER, which accounts for water as a production factor in different sectors, providing a framework to analyze global virtual water trade and the economic analysis of different water uses at the regional level.
