Policy design tool for managing indoor residential water demand in water-scarce regions
<p>In view of population growth; climate change; and economic evolution, water resources in numerous parts of the world have reached their natural capacities. Consequently, the ability of many countries to grow; meet the basic needs of inhabitants; and protect the environment will be endangered …

"On the location of zeros of solutions to w"" + Aw = 0 for certain entire functions A"
… we show that there exist both ""zero-scarce"" regions and ""zero-rich"" regions. We call an unbounded region in the complex plane ""zero-scarce"" if every nontrivial solution of $(\*)$ has only finitely many zeros in the region. In contrast, a region is called ""zero-rich"" if there …

The development of Intensity Duration Frequency curves under climate change considerations using Remote Sensed rainfall data in Uganda
… infrastructure, particularly in data-scarce regions such as Uganda. Reliable intensity–duration–frequency (IDF) curves are essential for climate-resilient design, yet their development is constrained by the lack of long-term subdaily rainfall records. The challenge addressed in this …

The analysis of water availability indicators and access to available water in the developing, semi-arid, rural setting
… water; the majority lived in the rural, water scarce regions of lesser developed nations. Global discussions of water scarcity had begun in the mid-1970’s, and over the following 30 years, several water availability indicators evolved to try to understand this water availability quandary. This …

Flood risk modeling and impact assessment using google earth engine in Mpumalanga province, South Africa
… agriculture, and human settlements. In many regions, recurrent flood events continue to hamper disaster management programmes, largely due to the limited availability of near real-time monitoring systems and comprehensive risk assessment frameworks. This study aimed at addressing these …

Long-Term Lab Scale Studies of Simulated Reclaimed Water Distribution: Effects of Disinfectants, Biofiltration, Temperature and Rig Design
… higher temperatures >22°C common to many water scarce regions. The severe nitrification at the warmer temperatures rapidly depleted chloramine residuals, decreased dissolved oxygen, and caused elevated levels of nitrifiers and heterotrophic cell counts. A metagenomic taxonomic survey revealed …

Assessing graphene oxide for water desalination applications
… in augmenting the fresh water supplies for water scarce regions. However, despite considerable improvements in system efficiencies, it still remains six to ten times more expensive than treating freshwater for drinking. As a result, the construction and operation of a desalination plant places …

Quantifying the life cycle water consumption of a passenger vehicle
… to assess the availability of water sources in regions around the world as future forecasts suggest that water demands will increase significantly for agricultural, industrial and human consumption while freshwater resources are being depleted. One such emerging issue is the effect of industrial …

Climatic and Anthropogenic Influences on Food and Water Security
… county growing period instances over the cropped regions of the US. Additionally, crop risks from droughts vary significantly both spatially and temporally. Only about 55% of the sites experiencing drier droughts have seen an increase in yield risk from these droughts. Ancillary climatic …

Evaluating the Occurrence, Fate and Human Health Risks of Contaminants of Emerging Concern in the Atlantis Managed Aquifer Recharge Scheme
… urban aquifers used for potable supply in water-scarce regions. However, the quality of these recharge waters is a concern, as they often contain contaminants of emerging concern (CECs) that may persist in groundwater and pose risks to human health if left untreated. This study aims to evaluate …

Osmotic mass exchangers for power generation and energy recovery : analysis and analogy to heat exchangers
… separation process which can provide water scarce regions with clean water for drinking or for agricultural use. Thermal distillation has historically been the dominant method for obtaining pure water, but today, reverse osmosis (RO) produces a greater percentage of the total desalinated …
