Global Monthly Water Scarcity: Blue Water Footprints versus Blue Water Availability
Freshwater scarcity is a growing concern, placing considerable importance on the accuracy of indicators used to characterize and map water scarcity worldwide. We improve upon past efforts by using estimates of blue water footprints (consumptive use of ground- and surface water flows) rather than water withdrawals, accounting for the flows needed to sustain critical ecological functions and by ...

Monitoring, testing and managing water quality: 3 vital technologies
Water is one of the most important natural resources on earth, an essential element for all life, so maintaining its quality is crucial for the health of both humans and the environment. Many factors continuously threaten the quality of water, from pollution and climate change to extreme weather events. To ensure the well-being of humans and nature alike, we must use every tool in our repertoire ...

Re-oligotrophication as a challenge for tropical reservoir management with reference to Itaparica Reservoir, São Francisco, Brazil
The process of reservoir eutrophication has been recognised as a central problem in tropical reservoir environmental quality. Effects of eutrophication are complex interactions involving a decrease in water quality, especially loss of aquatic biodiversity, occurrence of undesired species such as cyanobacteria with its cyanotoxins, mass development of macrophytes such as Egeria densa with its ...

Warming rivers endanger aquatic life, research unveils
Rivers across the globe are experiencing unprecedented rates of warming and loss of oxygen, endangering aquatic life. Recent findings from a Penn State-led study reveal that among almost 800 rivers examined, a staggering 87% have been warming, while 70% have been losing oxygen. For areas like the American South, the future could be even bleaker. Projections indicate that within seven decades, ...

The Role of Water Quality Sensors in Ensuring Sustainable Aquatic Ecosystems
Water quality sensors are innovative devices that measure various parameters related to water quality. These parameters include temperature, pH, dissolved oxygen, turbidity, nutrient levels, and contaminants. These sensors can be deployed in various aquatic environments, ranging from freshwater streams to deep sea habitats. They continuously collect data, providing real-time information on the ...

In search of effective bioassessment of urban stormwater pond sediments: enhancing the ‘sediment quality triad’ approach with oligochaete metrics
Stormwater ponds have been widely used to control increased volumes and rates of surface runoff resulting from urbanization. As receiving waters, they are under the influence of intermittent pollution from urban wet-weather discharges. Meanwhile they offer new aquatic habitats balancing the transformation of initial ecosystems and their associated biodiversity. Bioassessment of stormwater ...
