- Impact of Climate Variability and Change on the Water-Energy-Food Nexus
Water is an essential prerequisite for development and growth. In fact, all civilizations have evolved around water. Continuously increasing pressure on the fresh water resources and Land Use Land Cover transformations are becoming the cause of several problems such as depleting quantity & quality of water resources, severe drought conditions, damage of ecosystems and decreasing economic development. For example, deforestation and replacement for agricultural fields has consequences on water and food and water quality. Similarly, use of excessive fertilisers to increase crop yield has led to deterioration of water quality. Subsidy on electricity has also led to over exploitation of water resources and declining ground water levels leading to more energy consumption. Thus, there is a clear nexus between water-energy-food-water quality which needs to be well understood. Further, to deal with these problems, proper management, conservation and augmentation of water resources is required in order to secure the sustainable use of water resources. Recent advances in both cost-effective and high-tech measurement methods may help to achieve this.
The aim of this Research Topic is to evaluate the role of water quality in the water-energy-food nexus and to discuss approaches to water quality assessment within the nexus framework through original researches, with discussion of case-studies and analyses at different scales. This research topic mainly covers the following topics:
(a) Case-studies studying water quality in the water-energy-food nexus.
(b) Regional/global scale analyses and models of water quality in the water-energy-food nexus.
(c) Monitoring and assessment of water quality in the water–energy-food nexus-current approaches and novel techniques.
(d) Water quality management approaches informed by the water-energy-food nexus.
This Research Topic looks at the water-energy-food security nexus in the context of small to large river basins. The aim is to analyze what benefits the nexus approach could bring into these kinds of, often quite demanding, settings.
The thematic areas to be covered can thus include: water resources management; human-environment systems; sustainability; natural resources management; integrated approaches; health impact and risk assessment; policy and regulatory development and implementations.
The articles of this special collection may include case studies from relevant river basins, comparative analysis in several river basins, studies of institutional and policy mechanisms related to ‘nexus sectors’ as well as more theoretical discussions of the water-energy-food security nexus and its linkages to water quality as a focus, and approaches for sustainable development.
Keywords: water quality, water-energy-food nexus, water quality assessment, natural resources management, sustainable development, river basins
