when competition between sectoral water uses intensifies, agriculture is the most vulnerable sector to water scarcity42,43,44. However, due to its high water use volume and intensity, the potential for agricultural water conservation is also high. Therefore, one of the keys for addressing water ...
However, water scarcity has emerged as a significant threat to this vital resource, posing a global challenge. While discussions surrounding the consequences of water scarcity typically emphasizes its effects on physical health and socioeconomic impacts, the mental and psychological...
Water scarcitymay seem to be a problem of local water availability. However, its drivers are often global in nature due to globalization as several economic sectors, such asagriculture, energy, and transportation, rely heavily on reliablewater supplyfor their commodities to be traded and consumed ...
The Southern and Eastern Mediterranean region (hereafter SEMED) has been a focal area in the discussion on water scarcity and its impact on food security. This is not only because the region overall is poor in water resources and many countries are importing a large portion of food to meet ...
We calculate both physical water scarcity (Fig. 1B) and its economic impact (Fig. 1C) over the 21st century for 235 river basins for each of the 3000 global change scenarios, simulated using the Global Change Analysis Model (GCAM) integrated assessment model36. With the effects of inter-...
A combination of these factors has led to high levels of water scarcity and an immense burden on the water supply. However, it must be noted that in 1994, South Africa (SA) embarked on developing numerous policies and strategies to address water challenges. While some levels of success have...
(Fereres and Goldhamer, 1990).The number of countries that cultivate these species is very high;however, according to production, Asia and Europe are the most importantzones. Fig. 5.1 shows the distribution of 80% of world production forWater Scarcity and Sustainable Agriculture in Semiarid ...
and the environmental stability for the farming and ranching industries. According to the United Nations, forty percent of the world’s population is a victim of water scarcity, and the number is rising, which is why more recently this issue has become prominent with the media internationally. ...
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
With accelerated urban sprawl, water scarcity and increased water stress have become global issues. Water of building industry and domestic water are two major contributors to total water consumption that cannot be ignored. This paper seeks to emphasize the effects of urban sprawl on water competition...
