Changes in the Regional Water Cycle and Their Impact on Societies
Changes in “blue water”, which is the total supply of fresh water available for human extraction over land, are quite closely related to changes in runoff or equivalently precipitation minus evaporation, . This article examines how climate change‐driven recent past and future changes in the regional water cycle relate to blue water availability and changes in human blue water demand. Although at the largest scales theoretical and numerical model …
Low flow sensitivity to water withdrawals in Central and Southwestern Europe under 2 K global warming
A sufficient freshwater supply is vital for humans, ecosystems, and economies, but anticipated climate and socio-economic change are expected to substantially alter water availability. Across Europe, about two-third of the abstracted freshwater comes from rivers and streams. Various hydrological studies address the resulting need for projections on changes in river discharge. However, those assessments rarely specifically account for the impact o…
Water circles—a tool to assess and communicate the water cycle
‘Water circles’ are presented as flexible water cycle diagrams aggregating the flows through a system for a specific region and time period, categorized by flow type and organized by magnitude. Water circles for an entire system and separate storage components can be interpreted as water cycle speedometers and can help compare and communicate different climate and human impacts on different regions, time periods, and storage components. Water cir…
Co-development of East African regional water scenarios for 2050
The aridity Index under global warming
Aridity is a complex concept that ideally requires a comprehensive assessment of hydroclimatological and hydroecological variables to fully understand anticipated changes. A widely used (offline) impact model to assess projected changes in aridity is the aridity index (AI) (defined as the ratio of potential evaporation to precipitation), summarizing the aridity concept into a single number. Based on the AI, it was shown that aridity will generall…
A nexus modeling framework for assessing water scarcity solutions
Global exposure and vulnerability to multi-sector development and climate change hotspots
Understanding the interplay between multiple climate change risks and socioeconomic development is increasingly required to inform effective actions to manage these risks and pursue sustainable development. We calculate a set of 14 impact indicators at different levels of global mean temperature (GMT) change and socioeconomic development covering water, energy and land sectors from an ensemble of global climate, integrated assessment and impact m…
Global assessment of water challenges under uncertainty in water scarcity projections
Simulated changes in aridity from the last glacial maximum to 4xCO 2
Aridity is generally defined as the 'degree to which a climate lacks moisture to sustain life in terrestrial ecosystems'. Several recent studies using the 'aridity index' (the ratio of potential evaporation to precipitation), have concluded that aridity will increase with CO2 because of increasing temperature. However, the 'aridity index' is—counterintuitively—not a direct measure of aridity per se (when defined as above) and there is widespread …
