Water at the Global Scale
Community Water Model (CWatM)
An open source model to examine how future water demand will evolve in response to socioeconomic change and how water availability will change in response to climate. More
Global Hydro-economic Model (ECHO)
A new tool to inform the design of cost-effective and sustainable water policy decisions. More
Global Agro-ecological Zones (GAEZ)
Detailed assessment of available resources to support policymakers developing national, regional, and global strategies for the sustainable production of food More
Novel framework to address uncertainty in water management
IIASA researchers have developed a general decision-making framework to support policy decisions on the management of water resources, which, for the first time, explicitly takes into account the associated uncertainties. More
Global temperature rise of 2°C doubles the population exposed to multiple climate risks compared to a 1.5°C rise
New research identifying climate vulnerability hotspots has found that the number of people affected by multiple climate change risks could double if the global temperature rises by 2°C, compared to a rise of 1.5°C. More
Water management interventions push scarcity downstream
Human interventions to harness water resources, such as reservoirs, dams, and irrigation measures, have increased water availability for much of the global population, but at the same time, swept water scarcity problems downstream. More
Global food supply at risk from agricultural misuse of nonrenewable water
The rising use of unsustainable water supplies by international food producers is putting global food and water supplies at risk and could cause basic food prices to skyrocket, suggests a new study from international researchers. More
Better farm water management could help achieve UN Sustainable Development Goals
Around 40% of irrigated agriculture is unsustainable, according to a new study. However, better farm water management could help reconcile global water, environment, and food targets. More
Fossil groundwater vulnerable to modern contamination
A new study shows that over half of global groundwater is over 12,000 years old More
Traveling droughts bring new possibilities for prediction
Droughts can travel hundreds to thousands of kilometers from where they started, like a slow-moving hurricane. A new study sheds light on how these droughts evolve in space and time, bringing vital new insight for water managers. More
