virtual water tradegrid analysisThe best available high-resolution precipitation, GDP, available freshwater and withdrawal data sets are used in a combined global analysis of physical and economic water scarcity at 50km resolution. We find that approximately 40.7 million people are living in areas ...
Physical and economic water scarcity But why should you care? We should care because a lot of the factors that cause water scarcity are broadening and becoming more complex and uncontrollable. If we do nothing in terms of preserving and using it wisely, it is only a matter of time before a...
The inadequate availability of clean water presents systemic risks to human health, food production, energy generation and ecosystem functioning. Here we evaluate population exposure to current and future water scarcity (both excluding and including water quality) using a coupled global hydrological and ...
In this letter we analyse the temporal development of physical population-driven water scarcity, i.e. water shortage, over the period 0 AD to 2005 AD. This was done using population data derived from the HYDE dataset, and water resource availability based on the WaterGAP model results for the...
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 wate...
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
"Virtual water": An unfolding concept in integrated water resources management awareness of water scarcity and its impact on food security and to improve the understanding of the role of food trade in compensating for water deficit... Y Hong,A Zehnder - 《Water Resources Research》 被引量: 188...
One of the key challenges of SSP is provision of detailed socio-economic scenarios compared to SRES for impact, adaptation and vulnerability studies. In this study, a comprehensive global water scarcity assessment was conducted, using a state of the art global water resources model H08 (Hanasaki ...
A global water scarcity 777 assessment under Shared Socio-economic Pathways - Part 2: Water availability and 778 scarcity. Hydrol. Earth Syst. Sci. 17, 2393-2413. doi:10.5194/hess-17-2393-2013Hanasaki, N., Fujimori, S., Yamamoto, T., Yoshikawa, S., Masaki, Y., Hijioka, Y., ...
Three new structural factors underlie the most recent global crisis:(i); the fact that several high-population countries have joined the growthprocess; (ii); the increasing scarcity of environmental and certain naturalresources; and (iii); the extraordinary concentration of income and wealththat has...
