Space and Ground-based Earth Observations for Hazards Valuation and Disaster Risk Management in the Era of Climate Change

Abstract

Quantifying hazards and assessing the risks in the era of climate change using Space and Ground-based Earth Observations (SAGEOs) is playing a key role in facilitating the implementation of frameworks and are essential for observing and assessing how risks have changed in recent years, as well as tracking the reduction in the level of exposure of communities to the hazards. SGEOs provide the context, scale, and perspective needed to understand various hazards, such as floods, seismic activities, wildfire, and coastal erosion, and are crucial for informing risk reduction and disaster management efforts. Correspondingly, SAGEOs contribute to the development of early warning systems for climate-related hazards, supporting timely and effective disaster preparedness and response. The integration of SAGEOs supports risk-informed decision-making by providing essential information for vulnerability and exposure mapping, thus informing adaptation planning and the development of climate-resilient strategies. In conclusion, quantifying hazards and assessing the risks of climate change using SAGEOs is vital for understanding, monitoring, and mitigating the impacts of climate-related hazards. These observations provide valuable data for characterizing hazards, developing early warning systems, and informing risk reduction and disaster management efforts, thus playing a critical role in building climate resilience and reducing disaster risks.
