The Water Program

The Water Program was established in 2013 in conjunction with a flagship project, the Water Futures and Solutions Initiative (WFaS), which now forms the core of the Water Programs research.

The IIASA Water Program works across various water-related sectors and management scales. It studies a range of possible future socioeconomic changes and technological innovations.

The program seeks to incorporate water science into assessment and planning studies at the nexus of water, food, energy, and environmental security. Its aim is to establish a critical mass of water knowledge through development of new modeling tools and data collection.


  • To compile, consolidate, and enhance knowledge of global water supply and demand balances
  • To incorporate hydrology and hydrologic uncertainty into integrated assessment modeling efforts and scenario development
  • To provide a sound scientific basis for responding to current and future global water challenges by assessing the robustness and complementarity of portfolios of potential solutions.

Observation-driven research to inform better groundwater management policies

Groundwater maintains vital ecosystems and strongly influences water and energy budgets. Although at least 400 million people in sub-Saharan Africa depend on this valuable resource for their domestic water needs, the processes that sustain it and their sensitivity to climatic variability, are poorly understood. IIASA contributed to a study that looked into climate impacts on groundwater in light of changing climatic patterns in Africa.  More

Water research at IIASA

IIASA research programs have continually been active in water science since the Institute's inception in 1972. IIASA played a prominent role in various recent large integrated water projects: WATCH (Water and Global Change); SCENES (Scenarios for Europe and Neighbouring States).
