Water Management

The Zambezi Riparian Region (ZRR) is a lifeline and home to ∼40 million people who depend heavily on the river basin for their livelihood. It also furnishes 8 of its riparian countries with goods and services on which hydropower production and food security anchor. The sustainability of the ZRR is threatened by extreme climate events. Here, we interrogate consecutive dry days (CDDs), an effective metric of extreme climatic events with implications on drought-driven water availability. We use ensemble empirical mode decomposition (EEMD) to understand CDDs.

With the continuous development of human society, people's over-exploitation of nature leads to frequent environmental problems. A large number of floating objects appear on lakes, rivers, reservoirs and other water surfaces. Water floats have seriously damaged the ecological environment and directly threatened the survival and development of human beings. Therefore, for the sustainable development of human beings, we must solve the problem of water pollution. The detection of floating pollutants on water surface is the primary goal of water resource management.
This Personal View supports SDGs 3 and 6 by suggesting a scale-specific approach in which agricultural water use is embedded in a larger systems approach to allow the design of effective incentives to change and optimise agricultural water use.
This study provides new insights into the potential use of machine learning in hydrological simulations.

Loss and Damage studies have tended to focus on rapid-onset events with lesser attention to slow-onset events such as drought. Even when discussed, narratives around droughts emphasize implications on rural populations and there remain empirical and conceptual gaps on drought impacts in urban areas. We focus on losses and damages associated with urban drought and water insecurity through a review of interventions and policies in seven Asian countries. We find evidence of urban droughts leading to tangible losses (e.g. groundwater over-extraction, economic impacts) and intangible losses (e.g.

This review article examines observed and projected climate change impacts on water security across the world's drylands to the year 2100.

A hydro-economic assessment of the headwaters of the Nile River revealed the upstream-downstream linkages and interconnections among socio-economic development, climate change, and the environment.
A framework for understanding water's many functions for supporting, regulating, and stabilizing hydro-climatic, hydro-ecological, and hydro-social systems.
Water harvesting techniques have shown promising outcomes in mitigating risks, increasing yields and delivering positive influences on other ecosystems. A field study was conducted in Northern Jordan to assess the influence of combined in-situ water harvesting techniques, micro-catchment and mulching on soil moisture content, plant morphology, gas exchange [photosynthesis (Pn), transpiration (E), and stomatal conductance (gs)] and midday stem water potential (Ψsmd) of young pistachio (Pistacia vera cv. Ashori) trees.

This study analyzes the effects of a local water market formation on the efficiency of groundwater use productivity. These results demonstrate the role of a market-based groundwater allocation approach under water scarcity conditions.
