Climate and Resource Constrains Promote Water-Energy Nexus Based-Solutions

Water-Energy Nexus is gradually becoming an important concern for many sectors within water and energy sectors. This will put increasing pressures on policy-makers to revisit several national policies. Here are some few examples (some

The spatial-temporal variability of climate change impacts due to global warming, will force decentralization of water-energy policies in critical situations as there are no “one-size-fits-all” solutions. An example is given here where down-scaling of wastewater treatment using “Wetland Technology” can be a reality, e.g.; In these examples constructed wetlands can offer effective and efficient wastewater treatment especially when refined to enhance the overall treatment performance under different geographic  and energy constrains. We know from decades of European and North American research that constructed and natural wetlands can be used to clean polluted waters through various physical, chemical and biological processes. These wetlands can remove nutrients, metals, toxics and other problematic substances from wastewater prior to discharge in the natural environment. Furthermore, constructed wetland-based wastewater treatment-solutions offer several advantages as compared with “SBR and MBR” approaches (; and
