Global Warming and the Water-Energy-Food Nexus: Insights from Geo-Information and Earth Observation

<p><a name="OLE_LINK3"></a><em><span>Global warming, driven by anthropogenic greenhouse gas emissions, is a major threat to the sustainability of water, energy, and food (WEF) systems. These systems are deeply interconnected, and disruptions in one domain can cascade across the others, particularly in vulnerable regions. This article explores the multifaceted impacts of global warming on the WEF nexus, emphasizing the role of geoinformation science and Earth Observation technologies in monitoring and mitigating these effects. Drawing on comparative insights from Nigeria and India—two populous, climate-sensitive developing countries—the study highlights how climate-induced changes in precipitation, temperature, and extreme weather events compromise agricultural productivity, energy infrastructure, and water availability. The paper also examines the trade-offs and synergies inherent in WEF resource management, advocating for integrated, data-driven approaches to enhance resilience. By leveraging remote sensing, GIS, and satellite-based monitoring tools, stakeholders can gain a deeper understanding of spatial-temporal dynamics and inform more effective, sustainable policy interventions. The findings underscore the urgency of interdisciplinary strategies to address climate vulnerabilities and support the achievement of Sustainable Development Goals (SDGs) 2, 6, 7, and 13.</span></em></p>
