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 ...
متن کاملA global water scarcity assessment under Shared Socio-economic Pathways – Part 2: Water availability and scarcity
A global water scarcity assessment for the 21st century was conducted under the latest socio-economic scenario for global change studies, namely Shared Socioeconomic Pathways (SSPs). SSPs depict five global situations with substantially different socio-economic conditions. In the accompanying paper, a water use scenario compatible with the SSPs was developed. This scenario considers not only qu...
متن کاملAssessing the Sustainability of Groundwater Resources Using Water Exploitation and Green Water Scarcity Indicators
Sustainability of groundwater resources means ensuring the permanent availability of essential groundwater services for a long-time. This research was conducted to investigate the sustainability of groundwater resources in the prohibited plain of Behshahr- Bandar-e-Gaz by using water expoliation and green water scarcity indices. Initially, the green water deficit index was calculated based on t...
متن کاملFour 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...
متن کاملClimate-driven interannual variability of water scarcity in food production potential: a global analysis
Interannual climatic and hydrologic variability has been substantial during the past decades in many regions. While climate variability and its impacts on precipitation and soil moisture have been studied intensively, less is known on subsequent implications for global food production. In this paper we quantify effects of hydroclimatic variability on global “green” and “blue” water availability...
