PIR urbano na resiliência de cidades: nexo água e energia

The economic development, the population growth and the urbanization will increase water and energy world demand. As a consequence, the conflict between water resources and energy production will be intensified and the environment will be impacted by this competition. In addition to the direct influence of human activities, climate changes and extreme climate events have affected the water availability and, as consequence, the energy production. This article aims to discuss urban resilience in the context of the water and energy nexus, as well as to suggest a methodological alternative with a systemic approach. To do so, we present the integrated planning of resources (IRP) and the technique of scenarios as tools to help optimize the use of natural resources in the cities. As a result of the application of this methodology we have information for the public power to propose policies that lead to the equation of the complex relations and interdependencies of sustainability, which demand rapid and transversal answers for the different economic sectors present in the cities. The great advantage of this methodological framework (IRP and Scenarios) is the simultaneous treatment of vulnerabilities and the risks associated with the supply and demand of resources vis-a-vis the resilience of cities, as well as the connection between water and energy. The desire to have a more sustainable future, with lower emissions of carbon to the atmosphere, a more appropriate reuse and valorization of natural resources, and less dependency on oil have motivated society to develop methodologies where water and energy are used as news criteria focusing on urban cities and sustainability.
