Life Cycle Environmental Impacts and Decarbonisation Pathways of China’s Urban Water Systems
Urban water systems (UWSs) in China form an energy-intensive and intricate socio-technical network that links multiple components from water abstraction to sewage sludge disposal. As the country moves toward carbon neutrality, improving the environmental performance of the UWS has become essential. …

Exploring forest-water nexus in a changing environment of Kafue river basin, Zambia.
Water insecurity in Zambia's Kafue River Basin (KRB) is rising due to climate change, land-use change and increased water abstraction. The role of forests in the hydrological cycle, particularly through evapotranspiration (ET) has not been adequately explored. This study addressed this gap. The …

Information and Decision-Support for Robust Adaptation of Irish Water Resources to Climate Change
Anticipatory adaptation to climate change in the water resources sector is essential to reduce or avoid expected impacts on water resources availability and management. Anticipating how water systems are likely to respond to a changing climate is a challenging task, due to the difficulties in …

Altersbetrachtung und numerische Simulation zu Möglichkeit und Grenzen einer prozessorientierten Kontrolle (Frühwarnsystem) der Bewirtschaftung tiefer Grundwässer
Long-term threats to groundwater quality arising at regional scale from the exploitation of deep groundwaters, and some ways to tackle with them have been revealed by Seiler (1983, 1987, 2001), Seiler & Lindner (1995). They have shown that, once the passive recharge zone of a groundwater system is …

Water resources management in Zambia: a case of cumulative impacts associated with copper mining in the Upper Kafue Catchment, Copperbelt Province, Zambia
Water resources management is high on the agenda both locally and globally because of its important role in social, economic and environmental development. For example, as part of the 2030 Agenda for Sustainable Development, all United Nations Member States adopted 17 Sustainable Development Goals …
