The world's energy, water, and land (EWL) systems are in transition and are rapidly integrating, driven by forces such as socioeconomic, climatic, and technological changes, as well as policies intended to meet societal priorities such as the Sustainable Development Goals. These dynamics weave across spatial scales, connecting global markets to national, sub-national, and urban economies. At the same time, resources are often locally managed under varying administrative jurisdictions tied to the characteristics of each commodity, such as river-basins for water, grid-regions for electricity, and land-use boundaries for agriculture. Local decisions in turn are critical to the success of national-to-global policies. Thus, there is a need to better characterize EWL interactions to guide robust, consistent, trans-scale decision-making. This session invites multidisciplinary abstracts exploring EWL dynamics, hotspots, trade, policies, infrastructure planning and uncertainty characterization across variable boundaries. Studies exploring the impacts of these dynamics on security, health, and conflict are also welcome.
