Water is not only the basis of life for animals and plants, but is also likely to become a contested resource in parts of the world in the coming decades.According to UN figures, global water stress, i.e. the proportion of water withdrawn for use in industry, agriculture or private house...
Urbanization and climate change are together exacerbating water scarcity—where water demand exceeds availability—for the world’s cities. We quantify global urban water scarcity in 2016 and 2050 under four socioeconomic and climate change scenarios, an
UN United Nations; CWM city water map; UWB urban water blueprint Full size image First, we measured the scarcity risk of each city based on the water stress index (WSI) of the catchment in which the city is located (Table 1). The WSI equals the ratio of water use to water supply ...
food (WF Nexus) in several regions across the globe, as they are presently facing water problems related to stress, shortages, pollution, distribution, and climate change, as well as inequity in water distribution, representing a violation of the “water right” as being a basic human right. ...
Knowing the extent of human influence on the global hydrological cycle is essential for the sustainability of freshwater resources on Earth1,2. However, a lack of water level observations for the world’s ponds, lakes and reservoirs has limited the quant
Overlay analysis was performed after assigning an appropriate ratings and weights to each layer, and finally, the vulnerability map of the Noyyal Basin was obtained. The vulnerability map of the study is classified into five groups ranging from very low to very high degree of vulnerability. The...
A classic example of this is the Aral Sea, which was once the world’s fourth largest body of inland water but has shrunk to a fraction of its former size because of the diversion of its inflowing rivers for agricultural irrigation. water stress projectionsWorld map of projected water stress...
for leaf/canopy water status; (2) Derive a new temporally transferrable vegetation water stress index from the newly constructed feature space of SWIR–NDVI–LST; (3) Evaluate the performance of the proposed index against the widely used vegetation water stress indices such as PDI, MPDI, MVWSI...
Visualisation of Similarity Viewer (VOSviewer): the clean CSV file was entered into the program for the generation of the Author Keyword map, indicating the link between the most frequent words related to the life cycle of groundwater. In recent years, this software has been applied in several...
Urban growth is increasing the demand for freshwater resources, yet surprisingly the water sources of the world's large cities have never been globally assessed, hampering efforts to assess the distribution and causes of urban water stress. We conducted the first global survey of the large cities...
