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 کاملMulti-resolution integrated assessment and modelling of climate change impacts on water resources in arid and semiarid regions
Approximately one-third of the Earth’s land surface is considered to be arid or semiarid. The availability of water in such regions is particularly sensitive to climate variability while the demand for water is experiencing an explosive increase as populations continue to grow. The competition for available freshwater is exerting considerable pressure on the management of available water resour...
متن کاملEvaluation of Alternative Livelihoods Status in Arid and Semiarid Regions of Iran to Improve Sustainability
Abstract. From the perspectives of many environmental and conservative policy makers, improving and diversifying the livelihoods have been found as a mechanism to promote the livelihoods and persuade people to avoid the overexploitation and degradation of natural resources. Due to the fragility of the environment and inconsistency of incomes, the alternative income sources may be promised to wa...
متن کاملCoupled modeling approach to assess climate change impacts on groundwater recharge and adaptation in arid areas
The effect of future climate scenarios on surface and groundwater resources was simulated using a modeling approach for an artificial recharge area in arid southern Iran. Future climate data for the periods of 2010–2030 and 2030–2050 were acquired from the Canadian Global Coupled Model (CGCM 3.1) for scenarios A1B, A2, and B1. These scenarios were adapted to the studied region using the delta-c...
متن کاملGrowing sensitivity of maize to water scarcity under climate change
Climate change can reduce crop yields and thereby threaten food security. The current measures used to adapt to climate change involve avoiding crops yield decrease, however, the limitations of such measures due to water and other resources scarcity have not been well understood. Here, we quantify how the sensitivity of maize to water availability has increased because of the shift toward longe...
