Sea Ice Targeted Geoengineering Can Delay Arctic Sea Ice Decline but not Global Warming
(
- Earth's Future
, 2019)
To counteract global warming, a geoengineering approach that aims at intervening in the Arctic ice-albedo feedback has been proposed. A large number of wind-driven pumps shall spread seawater on the surface in winter to ...
Soil organic carbon allocation and dynamics under perennial energy crops and their feedbacks with soil microbial biomass and activity
(
- Soil Use and Management
, 2020)
The cultivation of perennial instead of annual energy crops has received growing interest. Previous studies identified numerous beneficial effects of perennial energy crop (PEC) cultivation for the agricultural landscape ...
Global distribution of oxygenated polycyclic aromatic hydrocarbons in mineral topsoils
(
- Journal of Environmental Quality
, 2021-05-06)
Hazardous oxygenated polycyclic aromatic hydrocarbons (OPAHs) originate from combustion (primary sources) or postemission conversion of polycyclic aromatic hydrocarbons (PAHs) (secondary sources). We evaluated the global ...
Importance of sources of variability, scales and experimental design: A case study about the effects of biochar and slurry application on soil properties in agricultural silty loam soils
(
- European Journal of Soil Science
, 2021-05-12)
In designed experiments, different sources of variability and an adequate scale of measurement need to be considered, but not all approaches in common usage are equally valid. In order to elucidate the importance of sources ...
Adoption of multiple sustainable land management practices among irrigator rural farm households of Ethiopia
(
- Land Degradation & Development
, 2021-09-29)
Using a household and plot‐level survey conducted in Ethiopia, this study analyses the difference in farmers' adoption of sustainable land management (SLM) practices between their rainfed and irrigated plots. The paper ...
Climate Change Can Accelerate Depletion of Montane Grassland C Stocks
(
- Global Biogeochemical Cycles
, 2021-10-08)
Climate warming and management will likely affect carbon (C) fluxes of montane grassland ecosystems. In this study, we assessed the effect of simultaneous warming (+2°C) and decreased precipitation (−25%) on carbon exchange ...
A framework for drinking water basin protection
(
- Water and Environment Journal
, 2021-06-02)
Many countries have applied many measures, including preventing inappropriate activities in areas where drinking water is abstracted to protect drinking water resources. However, reaching good water quality based on human ...
The Eco‐Exposome Concept: Supporting an Integrated Assessment of Mixtures of Environmental Chemicals
(
- Environmental Toxicology and Chemistry
, 2021-12-29)
Organisms are exposed to ever‐changing complex mixtures of chemicals over the course of their lifetime. The need to more comprehensively describe this exposure and relate it to adverse health effects has led to formulation ...
Seasonal Differences in the Attenuation of Polar Trace Organics in the Hyporheic Zone of an Urban Stream
(
- Water Resources Research
, 2022-01-20)
Attenuation of trace organic compounds (TrOCs) in a river occurs to a large extent in its hyporheic zone. A major part of the attenuation of polar TrOCs is of microbial origin. As microbial activity depends on temperature ...
Comparison of Denitrification Induced by Various Organic Substances—Reaction Rates, Microbiology, and Temperature Effect
(
- Water Resources Research
, 2021-11-18)
Widespread groundwater pollution with nitrate (NO3−) and the finite and decreasing geogenic NO3− degradation capacity in aquifers require a better understanding of potential treatment methods. This project aimed at exploring ...
