  • Ecosystems that provide fresh water for cities also impact sediment flows, flood mitigation and hydropower provision. This Article looks at over 300 cities globally to gauge the interactions of natural ecosystems with built infrastructure.

  • Changes in terrestrial water storage are likely to affect sea level, but comprehensive and reliable data are scarce. Simulations of global terrestrial water stocks and flows, with an integrated model that specifically accounts for human activities, indicate that groundwater depletion and reservoir storage have together led to a sea-level rise of about 0.66 mm yr−1 between 1961 and 2003, about 36% of the observed rise.

  • Although irrigation expansion during the 20th century masked or even reversed local warming trends over some intensely irrigated regions, the exposure to moist-heat extremes of local population has increased due to higher air humidity.

  • Total water storage in Eurasia can be driven by both climate variability and human activities, with the latter suggested as the key factor for water loss. However, here the authors show that drying in the low-latitude Atlantic Ocean is the dominant force in storage depeletion during 2003-2017.

  • This research explores the emergence and resolution of water scarcity. The results indicate that water scarcity is likely to become predominant in Africa by 2090. Conversely, China might experience alleviation from water scarcity post-2050, attributed to its declining population.

  • Extreme weather patterns prove particularly detrimental to sustainable development when they occur as compound phenomena. Compound drought–heatwave events are projected to increase up to tenfold and negatively impact socio-economic productivity and potential terrestrial carbon sequestration.

  • Hydrological alterations caused by booming hydropower dams in the Mekong River basin are disrupting aquatic ecosystems and local livelihoods, calling for an urgent rethinking of hydropower development. Alternative operating strategies of existing Mekong dams could help restore the natural hydrological regimes without affecting power generation.

  • Weakening blocking effect of the High Mountain Asia on the westerlies-carried deficit in precipitation minus evaporation from the southeast North Atlantic is demonstrated, leading to persistent northward expansion of terrestrial water storage deficit in the Tibet Plateau.

  • Significant regional disparities exist in the time left to prepare for unprecedented drought and how much we can buy time depending on climate scenarios. Specific regions pass this timing by the middle of 21st century even with stringent mitigation.

  • Projections of terrestrial water storage (TWS)—the sum of all continental water—are key to water resource and drought estimates. A hydrological model ensemble predicts climate warming will more than double the land area and population exposed to extreme TWS drought by the late twenty-first century.

  • In-stream turbines could be a viable alternative to storage-based large hydropower projects. This study finds that about two-thirds of the planned hydropower generation in the Brazilian Amazon basin could be harnessed using in-stream turbines.

  • Impact models projections are used in integrated assessments of climate change. Here the authors test systematically across many important systems, how well such impact models capture the impacts of extreme climate conditions.

  • The geographical distribution of flood risk in the Mekong Basin has changed as a result of shifts in extreme precipitation from tropical cyclones as well as population exposure and is projected to continue to evolve, according to simulations with a hydrological-hydrodynamic model and observations.

  • Irrigation accounts for a substantial proportion of global water usage and can have biophysical and biogeochemical impacts on Earth systems. This Review outlines key irrigation–Earth system interactions, and discusses the effect of future climate and socioeconomic changes on irrigation patterns and their interaction.
