Why we need Regional Earth System Models to achieve Urban- Food - Energy - Water Sustainability under Climatic Extremes?
Abstract
This invited perspective will make a case for the development of region-specific earth system models as the next generation efforts that will allow the integration of the biophysical and the human interventions to help achieve an improved understanding of the food-energy-water-sustainability especially for urban settings in the face of increasing propensity and vulnerability from climatic extremes. Recent examples of urbanization and agricultural intensification pressures over regional landscapes are assessed, along with the climatic and societal feedbacks such changes lead to in the hydroclimatic setting. The need to consider processes of different complexity and, multiscale forcings as well as their feedbacks to get a more realistic scenario generation, as well as process representation, is presented. The objective of these models need not be only restricted in creating the process-scale understanding but could also transcend into being an effective if-then scenario assessment tool where local and regional adaptation and mitigation practices (management as well as human intervention) can be integrated. Thus the regional EaSM framework will help create a bi-directional workflow that translates the perspective of climate information to be Useful to Usable (U2U) keeping societal decision-making as the focus.A framework for such development will also be presented.
