The energy–water nexus has been studied predominantly through discussions of policy options supported by data surveys and technology considerations. At a technology level, there have been attempts to optimize coupling points between the electricity and water systems to reduce the water-intensity of technologies in the former and the energy-intensity of technologies in the latter. To our knowled...

The paper discusses an integrated approach to the management of three primary resources: water, energy, and food (WEF), as these increasingly represent the greatest global risks because they are expected to be highly impacted by climate change, demographics, aging infrastructure, and other challenges in the twenty-first century. As background, the WEF nexus is defined; significant historical de...

The two major conservation issues for drylands of Africa are habitat loss or degradation and habitat fragmentation, largely from agriculture, charcoal production, and infrastructural development. A key question for management is how these landscapes can retain their critical ecological functions and services, while simultaneously supporting resilient livelihoods. It is a clear nexus question in...

A system of a systems approach that analyzes energy and water simultaneously is called energy-water nexus. Neglecting the interrelationship between drives vulnerabilities whereby limits on one resource can cause constraints other resource. Power plant production directly depends availability, an outage power will affect wastewater treatment facility processes. Therefore, it essential to integra...

The water footprint of the urban environment is not limited to direct water consumption (i.e., municipal supplies); embedded water in imported resources, or virtual water transfers, provides an additional component of the urban water footprint. Using empirical data, our analysis extends traditional urban water footprinting analysis to quantify both direct and indirect urban resources for the Un...

The Earth's population is expected to exceed 9 billion by 2050, posing significant challenges in meeting human needs while minimally affecting the environment. To support this population, we will need secure and safe sources of food, energy, and water. The nexus of food, energy, and water is one of the most complex, yet critical, issues that face society. There is no more land to exploit, and t...

VoIP applications are getting popular due to their features of low cost and convenience. They have a high business potential over Wi-Fi or 3G network for smartphones applications. One possible barrier to the widespread adoption could be the high power consumption. And this in turn is due to higher CPU utilization introduced by sophisticated encryption algorithms for the sake of security. In thi...
