Maciej Liro, Tim van Emmerik, Anna Zielonka, et al.

Published: 2022-11-09
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 [...]

Seasonally-decomposed Sentinel-1 backscatter time-series are useful indicators of peatland wildfire vulnerability

Koreen Millard, Samantha Darling, Nicolas Pelletier, et al.

Published: 2022-10-22
Subjects: Environmental Monitoring, Natural Resources and Conservation, Other Environmental Sciences

Peatlands throughout the boreal forest are expected to experience changes in precipitation, evapotranspiration and temperature due to climate change. Correspondingly, changes in hydrologic regimes could lead to increased drought and occurrence of wildfire. Fire management agencies require information about near-real time wildfire vulnerability in boreal peatlands. Remote sensing tools (e.g., [...]

Groundwatersheds of protected areas reveal globally overlooked risks and opportunities

David Serrano, Xander Huggins, Tom Gleeson, et al.

Published: 2022-09-23
Subjects: Natural Resources and Conservation, Water Resource Management

Protected areas are a key tool for conserving biodiversity, sustaining ecosystem services and improving human well-being. Global initiatives that aim to expand and connect protected areas generally focus on controlling ‘above ground’ impacts such as land use, overlooking the potential for human actions in adjacent areas to affect protected areas through groundwater flow. Here, we assess the [...]

Fighting symptom or root cause? - The need for shifting the focus in climate politics from greenhouse gases to environmental protection

Thomas Rinder, Frederike Neuber, Christoph von Hagke

Published: 2022-08-16
Subjects: Environmental Sciences, Natural Resources and Conservation, Natural Resources Management and Policy, Social and Behavioral Sciences, Sustainability

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 [...]

An Artificial Neural Network Emulator of the Rangeland Hydrology and Erosion Model

Mahmoud Saeedimoghaddam, Grey Nearing, Mariano Hernandez, et al.

Published: 2022-06-17
Subjects: Artificial Intelligence and Robotics, Dynamic Systems, Hydrology, Natural Resources and Conservation

Machine learning (ML) is becoming an ever more important tool in hydrologic modeling. Many studies have shown the higher prediction accuracy of the ML models over traditional process-based ones. However, there is another advantage of ML which is its lower computer time of execution. This is important for the applications such as hydraulic soil erosion estimation over a large area and at a finer [...]

Contemporary Remote Sensing Tools for Integrated Assessment and Conservation Planning of Ice-free Antarctica

Larissa Patricio-Valerio, Justine Shaw, Felipe Gonzalez, et al.

Published: 2022-06-17
Subjects: Environmental Monitoring, Natural Resources and Conservation, Remote Sensing

Monitoring and understanding Antarctica is critical for conservation of its values. Remote sensing has been increasingly employed to observe large areas at higher frequency than traditional monitoring methods, enabling systematic assessments at low cost. However, currently there are limitations in the ability of the available remote sensing tools to answer the most pressing scientific, [...]

PING-Mapper: open-source software for automated benthic imaging and mapping using recreation-grade sonar

Cameron Bodine, Daniel David Buscombe, Rebecca J Best, et al.

Published: 2022-06-14
Subjects: Environmental Monitoring, Hydrology, Natural Resources and Conservation

The characterization of benthic habitats is essential for aquatic ecosystem science and management, but is frequently limited by waterbody visibility and depth. Recreation-grade side scan sonar systems are increasingly used to aid scientific inquiries in shallow water due to their relative low-cost, ease of operation, low-weight, and ease of mounting on a variety of vessels. However, existing [...]

The historical impact of anthropogenic air-borne sulphur on the Pleistocene rock art of Sulawesi

Michael Gagan, Halmar Halide, Raden Permana, et al.

Published: 2022-05-31
Subjects: Earth Sciences, Environmental Indicators and Impact Assessment, Environmental Sciences, Geochemistry, Natural Resources and Conservation

The Maros-Pangkep karst in southwest Sulawesi, Indonesia, contains some of the world’s oldest rock art. However, the Pleistocene images survive only as weathered patches of pigment on exfoliated limestone surfaces. Salt efflorescence underneath the case-hardened limestone substrate causes spall-flaking, and it has been proposed that the loss of artwork has accelerated over recent decades. Here, [...]

Paleoclimate controls on lithium enrichment in Great Basin Pliocene-Pleistocene lacustrine clays

Catherine A Gagnon, Kristina Butler, Elizabeth Gaviria, et al.

Published: 2022-05-29
Subjects: Climate, Earth Sciences, Environmental Sciences, Geochemistry, Geology, Natural Resources and Conservation, Other Environmental Sciences, Sedimentology

Terminal lakes are important archives of continental hydroclimate and in some cases contain important economic resources. Here we present an ~3.6 Myr lacustrine carbonate carbon and oxygen stable isotope record from a Great Basin continental drill core. We pair these measurements with bulk lithium concentrations to reveal a relationship between past climate and lithium enrichment in authigenic [...]

Groundwater connections and sustainability in social-ecological systems

Xander Huggins, Tom Gleeson, Juan Castilla-Rho, et al.

Published: 2022-04-08
Subjects: Dynamical Systems, Hydrology, Natural Resources and Conservation, Natural Resources Management and Policy, Nature and Society Relations, Sustainability, Water Resource Management

Groundwater resources are connected with social, economic, ecological, and Earth systems. We introduce the framing of groundwater-connected systems to better represent the nature and complexity of these connections in data collection, scientific investigations, governance and management approaches, and education. Groundwater-connected systems are social, economic, ecological, or Earth systems [...]

Reproducibility, the extent to which consistent results are obtained when an experiment or study is repeated, sits at the foundation of science. The aim of this process is to produce robust findings and knowledge, with reproducibility being the screening tool to benchmark how well we are implementing the scientific method. However, the re-examination of results from many disciplines has caused [...]

Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

As part of the UN Sustainable Development Goal 15 (Life on Land), the indicator 15.3.1 is adopted to measure the Land Degradation Neutrality. Land Degradation Neutrality is addressed as stable —or increasing— state in the amount and quality of land resources required to support ecosystem functions and services and enhance food security during a certain period of time. It is a binary indicator [...]

High resolution, annual maps of field boundaries for smallholder-dominated croplands at national scales

Mapping the characteristics of Africa's smallholder-dominated croplands, including the sizes and numbers of fields, can provide critical insights into food security and a range of other socioeconomic and environmental concerns. However, accurately mapping these systems is difficult because there is 1) a spatial and temporal mismatch between satellite sensors and smallholder fields, and 2) a lack [...]
