Comprehensive Assessment of Gran Canaria Food-Energy-Water Nexus with GIS-Based Tool

Abstract

Over the last centuries resource consumption has increased in such a way that compromises the planet’s ability to provide them in a sustainable manner (Daher and Mohtar in Water Int 40(5–6):748–771, 2015 [1]). Activities related to economic development have led to impacts in the environment. These include stress and contamination of water, land, fishing, as well as the GHG emissions related to the economic activity. Manufacturing, growing vegetables, feeding animals, or international trade are some of the most resources–taking activities related to societies. As life becomes more inwardly realized, there is growing needs of energy for the welfare of homes, for its construction, and decommissioning. This led international organizations to face this growing problem. In this sense, Brundtland Commission (World Commission on Environment and Development in Brundtland Commission. Our common future, from one earth to one world. The General Assembly of the United Nation, 1973 [2]) stated in 1973 that sustainable development consists in securing water, energy and food supplies for current and future generations, while maintaining a healthy and unharmed environment. Not only UN constantly alerts and gives indications such as sustainable development goals (United Nations. Sustainable Development Goals, 2020 [3]), but also researchers that investigate the nexus among the water, energy, and food systems for a better understanding of the synergies, are intended to provide a decision framework for the decision makers.
