Four billion people facing severe water scarcity

Four billion people facing severe water scarcity.

Freshwater scarcity is increasingly perceived as a global systemic risk. Previous global water scarcity assessments, measuring water scarcity annually, have underestimated experienced water scarcity by failing to capture the seasonal fluctuations in water consumption and availability. We assess blue water scarcity globally at a high spatial resolution on a monthly basis. We find that two-thirds...

Facing Water Scarcity in Jordan Reuse, Demand Reduction, Energy, and Transboundary Approaches to Assure Future Water Supplies

Jordan is extremely water-scarce with just 167 m3 per capita per year to meet domestic, industrial, agricultural, tourism, and environmental demands. The heavy exploitation of water resources has contributed to declines in the levels of aquifers and the Dead Sea. Rapid growth in demand, particularly for higher quality water for domestic, industrial, and tourism uses, is significantly increasing...

Water access, water scarcity, and climate change.

This article investigates the approaches of the various discourses operating in the water sector and how they address the issues of scarcity and equitable access under projected climate change impacts. Little synergy exists between the different approaches dealing with these issues. Whilst being a sustainable development and water resources management issue, a holistic view of access, scarcity ...

Facing data scarcity using variable feature vector dimension

This paper focuses on three key points of intonation modelling: interpolation of fundamental frequency contour, sentence by sentence parameter extraction and data scarcity. In some cases, they introduce noise and inconsistency on training data reducing the performance of machine learning techniques. We consider that the F0 contour is segmented into prosodic units (such as accent groups, minor p...
