Degradation

Polycyclic aromatic hydrocarbons (PAHs) in water pose a serious threat to human health due to their toxic effects. This manuscript evaluates various drinking water treatment processes to remove these compounds from drinking water, in order to assure the quality of water intended for human consumption.
This paper touches upon virus removal technology for groundwater remediation.
Droughts are extreme events that have major impacts on communities, ecosystems and economies due to slow onset and complex processes. Land and ecosystem degradation increase the risks of loss and damage during droughts, whereas well-adapted practices and policies can enable society to (re)build resilience. This review highlights actions needed to connect and fill gaps in the present systems for ecological and hydrological monitoring, governance, and alignment of economic incentives at regional, national and local scales.
In many tropical regions, such as New Caledonia, soil erosion from anthropogenic activities and subsequent ecological restoration are major issues that require detailed soil and vegetation data for the production of management plans. To determine if some plant species are more useful for stabilizing soil aggregates and thus reducing erodibility, we examined three species endemic to New Caledonia, and measured how root traits and associated mycorrhizas and fungi influenced Ferralsol aggregate stability (MWD).
