The initial WFaS Fast-Track scenario analysis was completed in December 2015. This constitutes the first comprehensive, multi-model assessment of water availability and demand, with full consistency of climate, energy, and land-use scenarios. A set of scenarios with water projections consistent with global scenarios in other sectors are used to identify the challenges of securing water, food, and energy security. This analysis is based on the Shared Socioeconomic Pathways and the Representative Concentration Pathways and climate projections that were developed for the Intergovernmental Panel on Climate Change Fifth Assessment Report.
WAT’s activities have also spanned a number of case studies including India, China, Peru, Nepal, and the US-Mexico border region of the Rio Grande basin. The program has performed regional scenario analyses for these and developed approaches for ensuring cross‐scale consistency. This allows assessment of policy options and investigation of synergies and trade-offs of these options. Finally, the program has also built tools for communicating the results of these analyses to stakeholders.
The successful completion of the fast-track analysis under the global Water Futures and Solutions (WFaS) initiative, is a major achievement of the Water (WAT) Program. The analysis has yielded the first set of multi-model, quantified scenarios of water demand with a focus on the domestic, industrial, and energy sectors. More
The fourth version of the Global Agro-ecological Zones data portal (GAEZ v4) was released in 2015. This work is the result of a continued collaboration of the Water (WAT) Program with the Food and Agriculture Organization of the UN (FAO) to update key input data, extend model components, and complete a number of computer-intensive model simulations.

Under the Asian Development Bank’s (ADB’s) Water Financing Program, the Water (WAT) Program produced consistent and comprehensive projections for water futures in Asia, via the Water Futures and Solutions (WFaS) initiative. More
The Water (WAT) Program helped develop a new method for calculating land footprints. This combines the IIASA LANDFLOW model—which traces land embodied in trade and consumption—with environmental economic-accounting. Land footprints were also further analyzed by the program in terms of land quality, resource use, and environmental impacts. More
In collaboration with the Risk, Policy and Vulnerability (RPV) Program the Water (WAT) Program has continued to contribute to methods to enhance flood resilience. To this end, WAT has led development of the Flood Resilience System Framework (FLORES) to integrate disaster risk management and development perspectives. More
The Water (WAT) Program has developed comparative approaches for improving environmental governance of transboundary water resources along the Rio Grande/Río Bravo Basin and the Colorado River Basin, along the border between the US and Mexico. More
In 2015 the Water (WAT) Program carried out analysis for the project: Integrated Analysis and Modelling of Land Use Efficiency and Security under Rapid Agricultural Transformation in China. Land-cover changes associated with the rapid exodus of the rural population were investigated, along with rural-urban divisions and the reasons behind cropland abandonment. More
One of the goals of the Water Futures and Solutions (WFaS) initiative is to establish a knowledge hub for systems analytic approaches to water challenges. To facilitate this, the program has been working closely with the Intersectoral Impact Model Intercomparison Project (ISI-MIP) to help develop climate-impact models that fully incorporate water issues.
