In this session, I will demonstrate a powerful tool for assessing the geospatial economic impacts of policies, climate shocks, and environmental changes. The SIMPLE-G model provides a spatially resolved view of agricultural production, land use, water resources, and economic interactions across 2 million grid cells, enabling detailed analysis of global and regional systems. Participants will explore the I-GUIDE platform for hands-on experience in visualizing simulation outputs and applying the model to real-world scenarios. We will cover foundational concepts, model applications in climate adaptation, policy analysis, and resource management, with practical demonstrations of its use in environmental and agricultural research. This knowledge is ideal for researchers in geospatial, climate, hydrological, and environmental sciences, offering tools for simulating land, water, and agricultural systems to inform policy and environmental decision-making.
