Subjects: Applied Statistics, Climate, Environmental Public Health, Environmental Sciences, Environmental Studies, Other Environmental Sciences, Public Health, Social and Behavioral Sciences, Sustainability

The El Nino Southern Oscillation (ENSO) is a principal component of global climate variability known to influence a host of social and economic outcomes, but its systematic effects on human health remain poorly understood. We estimate ENSO’s association with child nutrition at global scale by combining variation in ENSO intensity from 1986-2018 with children’s height and weight from 186 surveys [...]

In the absence of a federal geologic repository or consolidated, interim storage in the United States, commercial spent fuel will remain stranded at some 75 sites across the country. Currently, these include 18 “orphaned sites” where spent fuel has been left at decommissioned reactor sites. In this context, local communities living close to decommissioned nuclear power plants are increasingly [...]

For the time period of January'2003 to January'2017, this pan-India study investigates the relationship of urbanization and population density with Ground Water Storage (GWS) indicated by Gravity Recovery and Climate Experiment (GRACE) derived terrestrial water storage changes (

Comparing patterns of hurricane washover into built and unbuilt environments

Eli Lazarus, Evan B Goldstein, Luke Taylor, Hannah Williams

Published: 2020-10-23
Subjects: Geomorphology, Nature and Society Relations, Physical and Environmental Geography, Sustainability

Extreme geohazard events can change landscape morphology by redistributing huge volumes of sediment. Event-driven sediment deposition is typically studied in unbuilt settings – despite the ubiquity of occurrence and high economic cost of these geohazard impacts in built environments. Moreover, sedimentary consequences of extreme events in built settings tend to go unrecorded because they are [...]

Serious Gaming for Water Resources Planning and Hazard Mitigation

Aarin Teague, Yusuf Sermet, Ibrahim Demir, Marian Muste

Published: 2020-08-03
Subjects: Civil and Environmental Engineering, Earth Sciences, Engineering, Environmental Education, Environmental Engineering, Environmental Sciences, Hydrology, Physical Sciences and Mathematics, Sustainability, Water Resource Management

Hydrological hazards lead to a broad range of socio-economic and environmental risks. The development of a resilient community and risk reduction heavily rely on the adoption of holistic watershed master planning whereby the adaptation options consider the risk associated with individual or multiple hydrological hazards occurring simultaneously at a specific location. Such planning approaches [...]

Crop residues are a key feedstock to bioeconomy but available methods for their estimation are highly uncertain

Crop residues are acknowledged as a key biomass resource to feed tomorrow’s sustainable bioeconomy. Yet, the quantification of these residues at large geographical scales is primarily reliant upon generic statistical estimations based on empirical functions linking the residues production to the primary crop yield. These useful yet unquestioned functions are developed either using direct evidence [...]

Framework for consequential life cycle assessment of pyrolysis biorefineries: A case study for the conversion of primary forestry residues

Patrick Brassard, Stéphane Godbout, Lorie Hamelin

Subjects: Bioresource and Agricultural Engineering, Civil and Environmental Engineering, Engineering, Environmental Engineering, Environmental Indicators and Impact Assessment, Environmental Sciences, Physical Sciences and Mathematics, Sustainability

The development of bioeconomy needs to accelerate in order to get rid of fossil fuels and products. The production of bio-based products and renewable energy sources from the thermochemical conversion of biomass can be a sustainable alternative. Pyrolysis is one of the thermochemical processes that can convert biomass into liquid (bio-oil), solid (biochar) and gaseous (non-condensable gases) [...]

Overview of recent land cover changes in the biodiversity hotspots

Xiangping Hu, Bo Huang, Francesca Verones, Otavio Cavalett, Francesco Cherubini

Subjects: Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Physical Sciences and Mathematics, Sustainability

Biodiversity hotspots are the most biologically rich, yet threatened, terrestrial regions. From 1992 to 2015, they underwent 148 Mha of land cover changes, including forest losses (56 Mha, of which 40 Mha caused by agricultural expansion), declines of shrubland or savannah (23 Mha), and urbanization (10 Mha). The three largest losses in forest areas occurred in Sundaland, Indo-Burma, and [...]

Contributions of paleoecology to Easter Island’s prehistory: a thorough review

Easter Island (Rapa Nui) is well known for the enigmas surrounding its unique megalithic statues, the moai, and the prehistoric (i.e., pre-European contact) Rapanui society that built them. These enigmas include, among others, the time of the island’s settlement, the geographical origin of the first settlers, the technology associated with moai transportation and emplacement, the occurrence (or [...]

Towards local bioeconomy: A stepwise framework for high-resolution spatial quantification of forestry residues

In the ambition of a transition from fossil carbon use, forestry residues are attracting considerable attention as a feedstock for the future bioeconomy. However, there is a limited spatially explicit understanding of their availability. Confronted with limited resources for extensive field measurement campaigns, there are also limited discussions on the best practices towards a harmonized [...]

The sustainability of beach nourishments: A review of nourishment and environmental monitoring practice

Franziska Staudt, Rik Gijsman, Caroline Ganal, Finn Mielck, Johanna Wolbring, H. Christian Hass, Nils Goseberg, Holger Schüttrumpf, Torsten Schlurmann, Stefan Schimmels

Beach nourishments are a widely used method to mitigate erosion along flood-prone sandy shorelines. In contrast to hard coastal protection structures, nourishments are considered as soft engineering, although little is known about the cumulative, long-term environmental effects of both marine sediment extraction and nourishment activities. Recent endeavours to sustain the marine ecosystem and [...]

A framework to quantify the human footprint in Africa using supply and demand of net primary production

The human-environment connection in the mostly rural drylands of Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. When plants remove carbon dioxide from the atmosphere through the process of photosynthesis, [...]

A multi-control climate policy process for a trusted decision maker

Subjects: Climate, Environmental Sciences, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Sustainability

Persistent greenhouse gas (GHG) emissions threaten global climate goals and have prompted consideration of climate controls supplementary to emissions mitigation. We present an idealized model of optimally-controlled climate change, which is complementary to simpler analytical models and more comprehensive Integrated Assessment Models. We show that the four methods of controlling climate damage– [...]

Danger of groundwater contamination widely underestimated because of shortcuts for aquifer recharge

Andreas Hartmann, Scott Jasechko, Tom Gleeson, Yoshihide Wada, Bartolomé Andreo, Juan Antonio Barberá, Heike Brielmann, Lhoussaine Bouchaou, Jean-Baptiste Charlier, W George Darling

Groundwater pollution threatens human and ecosystem health in many areas around the globe. Shortcuts to the groundwater through concentrated recharge are known to transmit short-lived pollutants into carbonate aquifers endangering water quality of around a quarter of the world population. However, the large-scale impact of such concentrated recharge on water quality remains poorly understood. [...]
