Groundwater dependent ecosystems – groundwater status indicators

open access: yesNatura Sloveniae, 2016
Within the framework of »Water Management Plan for the Danube River Basin and the Adriatic Sea 2015-2021 (NUV II)«, a study on the groundwater status of karst aquifers which are habitats of groundwater dependent ecosystems (GDEs) was carried out. Among them are the habitats of olms (Proteus anguinus), the endemic species of Dinaric karst.

Understanding and Regulating C–N Coupling Pathways for Electrocatalytic Urea Synthesis From CO2 and NO3−/NO2−

open access: yesAdvanced Science, EarlyView.
Understanding and regulating C–N coupling is central to electrocatalytic urea synthesis from CO2 and NO3−/NO2−. This review outlines representative coupling pathways, summarizes carbon‐ and nitrogen‐side intermediate regulation strategies, and highlights in situ/operando tools for mechanistic clarification and catalyst design. ABSTRACT Electrocatalytic

Efficient Model Calibration Using Submodels

open access: yesWater Resources Research
Groundwater models tend to become increasingly detailed to accommodate increasing data availability and higher accuracy demands from stakeholders. As runtimes increase almost quadratically with the number of model cells, this makes the models ever more ...

Non-renewable groundwater use and groundwater depletion: a review

open access: yesEnvironmental Research Letters, 2019
Abstract Population growth, economic development, and dietary changes have drastically increased the demand for food and water. The resulting expansion of irrigated agriculture into semi-arid areas with limited precipitation and surface water has greatly increased the dependence of irrigated crops on groundwater withdrawal.

Does Contract Farming Reduce Pesticide Use? Panel Data Evidence From Smallholder Farmers in China

open access: yesAgribusiness, EarlyView.
ABSTRACT The inappropriate and excessive use of pesticides poses a major threat to human and ecosystem health in the agri‐food sector. While existing studies have examined the potential of contract farming to address this issue, most have focused on large‐scale farms and relied on small or transactional datasets, often leaving the role of crop‐specific
