The Water Status in China and an Adaptive Governance Frame for Water Management

open access: yesInternational Journal of Environmental Research and Public Health, 2020
China is increasingly facing water-related problems, such as water scarcity, pollution, and overexploitation of groundwater. This paper discusses the water status in China and claims that governance is the cause of water-related problems. The structure of the current water management is analyzed to conclude that the control-command is a static approach

Uncertainty of chemical status in surface waters [PDF]

open access: yesScientific Reports, 2021
AbstractThis article addresses the issue of estimating Pom—the probability of misclassifying the chemical status confidence of a water body status assessment. The main concerns of the authors were chemical quality elements with concentrations in water bodies which are close to or even smaller than the limit of quantification (LOQ). Their values must be
