450 million people live on river deltas and thus on land that is precariously low above the sea level and sinking because of human activities and natural processes. Although global debates around coastal risk typically focus on sea level rise, it is sinking lands and rising seas that together endanger lives and livelihoods in river deltas. However, the ability to quantify and address those risks [...]

Over recent decades, seaports around the world have been expanding seaward through land reclamation at a scale and pace that geospatial analysis of global satellite imagery is now revealing. Understanding patterns of seaport growth is necessary to accurately estimate risk to seaport infrastructure from future coastal hazards. What the global trend in seaport expansion may mean for climate [...]

Global accessibility of groundwater remains highly uncertain

Robert Reinecke, Sebastian Gnann, Lina Stein, et al.

Published: 2023-02-11
Subjects: Geology, Hydrology, Sustainability, Water Resource Management

Groundwater is essential for maintaining healthy ecosystems and securing human access to freshwater. Here we show that current estimates of global groundwater accessibility by ecosystems and humans are highly uncertain. To quantify this uncertainty, we define three categories of accessibility and investigate four global groundwater models. Averaged across these models, we estimate that 23% [most [...]

Water scarcity is a major global problem with the potential to impact socioeconomic development and the environment. Currently, mitigating issues related to the lack of water has become an aim for the public and private sectors. Water scarcity can be estimated by the ratio between water use (withdrawal or consumption) and water availability (a minimum discharge), named Water Stress Index (WSI). [...]

The Dry Sky: Futures for Humanity’s Modification of the Atmospheric Water Cycle

Patrick W Keys, Lan Wang-Erlandsson, Michele-Lee Moore, et al.

Subjects: Atmospheric Sciences, Climate, Fresh Water Studies, Hydrology, Meteorology, Natural Resource Economics, Natural Resources Management and Policy, Nature and Society Relations, Sustainability, Water Resource Management

Humanity is modifying the atmospheric water cycle, via land use, climate change, air pollution, and weather modification. Given the implications of this, we present a theoretical framing of atmospheric water as an economic good. Historically, atmospheric water was tacitly considered a ‘public good’ since it was neither actively consumed (rival) nor controlled (exclusive). However, given [...]

Standardised indices to monitor energy droughts

Sam Allen, Noelia Otero

Published: 2022-12-01
Subjects: Applied Statistics, Environmental Sciences, Physical Sciences and Mathematics, Sustainability

To mitigate the effects of climate change, energy systems are becoming increasingly reliant on renewable energy sources. Since these energy sources are typically dependent on the prevailing weather, renewable energy systems are susceptible to shortages during certain weather conditions. As renewable sources become larger contributors to the energy mix, the risks associated with these shortages, [...]

Geophysical research frequently makes use of agreed methodologies, formally published software, and bespoke code to process and analyse data. The reliability and repeatability of these methods is vital in maintaining the integrity of research findings and thereby avoiding the dissemination of unreliable results. In recent years there has been an increased attention on aspects of reproducibility, [...]

The unknown fate of macroplastic in mountain rivers

Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Monitoring, Geology, Geomorphology, Hydrology, Life Sciences, Natural Resources and Conservation, Sedimentology, Stratigraphy, Sustainability, Terrestrial and Aquatic Ecology, Water Resource Management

Mountain rivers are typically seen as relatively pristine ecosystems, supporting numerous goods (e.g., water resources) for human populations living not only in the mountain regions but also downstream from them. Recent evidence suggests, however, that mountain river valleys in populated areas can be substantially polluted by macroplastic (plastic item > 5 mm). It is, however, unknown how [...]

Air Quality-Related Equity Implications of U.S. Decarbonization Policy

Addressing the environmental crisis requires a substantial change of our current lifestyle. Yet, in media coverage and political communication, climate change has taken the lead over other aspects such as biodiversity loss and one may sometimes get the impression that reducing greenhouse gas emissions is fighting the root cause itself. The atmosphere, however, does not respond linearly to our [...]
