Macro-Index for the Assessment of the Water-Energy-Food Nexus: Toward Accessibility and Sustainability of Resources

The evaluation of the water-energy-food nexus is one of the most relevant issues today. Decisions and action plans are essential for the sustainable management of resources. This paper proposes the use of a macro-index to facilitate the evaluation of the synergies within the water-energy-food nexus, exploring the interactions between resources, sustainable development, and human development. The macro-index considers resource accessibility, availability, and various social, economic, and environmental aspects and serves as a comprehensive indicator influenced by major economic, social, and environmental trends or developments. The macro-index measurements encompass sustainable development objectives and resource allocation, providing valuable guidance to decision-makers.
