In this study, we use the Global Change Assessment Model (GCAM), where interactions between population, economic growth, energy, land, and water resources interact simultaneously in a dynamically evolving system to explore the role of groundwater resources in meeting future demands for energy, water, and agricultural demands. 2 - Integrated Assessment of Water-Energy-Land Nexus Solutions The Indus river basin in South Asia is home to an estimated 300-million people. Its freshwaters are critical for human health and regional food and energy security. The Indus faces sustainable development challenges due to rapid population growth, climate change, and extreme water stress hampered by poverty and transboundary disputes. This presentation overviews a new multi- scalar integrated assessment framework that uncovers future pathways balancing basin-wide water, energy and land system interactions and constraints. Preliminary analysis identifies investments supporting infrastructure aligned with development targets. The new framework is readily transferable to other basins. 3 - Ending Groundwater Overdraft Globally? An Assessment of Water Groundwater plays an indispensable role in agricultural production. Yet, aquifers are being depleted in many arid and semi-arid areas. We modified a global water and food simulation model to assess the impacts of ending groundwater overdraft on water supply and food security. It was found that considerable decline in the production of major staple crops can be caused at the global scale, with immediate more severe regional impacts in heavy groundwater-using areas. International prices of significant groundwater-irrigated crop commodities like wheat were found to increase significantly, which potentially increases the population at risk of hunger in the world. 4 - The Land and Water Implications of Biomass Cofiring in the MISO Region Jing Liu, Pennsylvania State University, University Park, PA, United States, Shanxia Sun, Thomas W. Hertel, Brayam Valqui Biomass cofiring is a promising and efficient way to provide clean energy for the states that have created Renewable Portfolio Standards. In the MISO region, many power plants are targeting corn residue — the most available and cost effective biomass resource. Should biomass cofiring be widely adopted, the production of corn is expected to expand significantly. This change will have important implications for land and water quality, as corn production intensively uses nitrogen fertilizer and, in some area, water for irrigation as well. The main objective of this study is to explore the potential of biomass cofiring in the MISO region and the associated impacts on land and water resources. 5 - Modeling the Water-Energy Nexus at the Community Scale: A Case Study of New York City for the Indus River Basin Simon Parkinson, Austria and Food Security Impacts using Integrated Modeling Tingju Zhu, International Food Policy Research Institute, Washington, DC, United States, Karen G. Villholth, Edwin Sutanudjaja The sustainable supply and efficient use of energy, and the transformation from fossil fuels to renewable energy sources have become strategically important for cities. Regulatory approaches to achieve clean air goals applied on top-down basis tend to yield a significant amount of noncompliance costs. To address this challenge, a community scale, cost optimization linear programming model that focuses on buildings is developed to assess the energy supply systems and the related challenges toward resilient communities while combating climate change are examined in scenario analysis frame.

n SB49 North Bldg 230 Joint Session ENRE/Practice Curated:Data Analytics and Renewables in Oil & Gas Production Sponsored: Energy, Natural Res & the Environment/Natural Resources Petrochemicals Sponsored Session Chair: Sam Aminfard, University of Texas at Austin, Austin, TX, United States 1 - Electrifying Oil and Gas Wells With Renewable Energy Sam Aminfard, University of Texas at Austin Renewable sources such as solar energy can be utilized to power remote electrified well site control systems and to minimize emissions of greenhouse gases. To assess the viability of powering well sites with renewable energy, we first developed a tool to calculate time-varying power loads of electrified well site control systems. We then utilized a transient energy flow model to evaluate the solar power generation and energy storage needed to reliably meet the estimated power loads using on local energy resource availability. Finally, we assessed the feasibility of potential renewable energy and storage options with a life-of- operation economic study. 2 - Modeling Microgrids at Well Fields Sam Johnson, University of Texas at Austin, Austin, TX, 78756, United States, Jon La Follett High penetrations of renewable energy generation could increase downward pressure on electricity prices, which in turn could drive cogeneration plants to seek out alternative profit schemes. Likewise, regulations restricting emissions could motivate industrial electricity consumers to explore alternative power generation options. To identify an optimal operation strategy for facilities facing this predicament, a modeling framework was developed and applied to an existing microgrid. The reliability and resilience of on-site renewable energy generation and integrated energy storage were explored. 3 - Toward a Global Assessment Framework for Oil and Gas Sector GHG Emissions Adam Brandt, Stanford University, Mohammad S. Masnadi, Jeffrey Rutherford As the threat of global climate change increases, regulatory limits on the oil and gas industry is becoming more stringent, and long-term emissions reductions look increasingly likely. A particular challenge to addressing oil and gas emissions using current regulatory mechanisms (standards or taxes) is that the industry is profoundly global in nature and crude oil products can cross multiple jurisdictions before reaching consumers. Also, emissions data availability in the global oil industry is generally poor, with many of the data required to estimate emissions being considered proprietary or strategic in nature by companies and thus held closely to operators. We describe an effort to address these issues by developing a combined open-source GHG modeling platform that is data-rich and based on engineering fundamentals. We also describe recent efforts to compile global data sources into the first comprehensive picture of global oil sector emissions, with an emphasis on data and analytical challenges. n SB50 North Bldg 231A Joint Session Practice/Practice Curated Editor’s Cut #2: Human Trafficking, Crowdsourcing, Retail Sponsored: Practice Curated Track Sponsored Session Chair: Carrie Beam, University of Arkansas, Walnut Creek, CA, 94596, United States 1 - Moderator, Editor’s Cut Panel #2 (Human Trafficking, Crowdsourcing, Retail) Renata Alexandra Konrad, Worcester Polytechnic Institute, School of Business, 100 Institute Road, Worcester, MA, 01609, United States This panel will cover the Human Trafficking, Crowdsourcing, and Retail issues of Editor’s Cut.
