Climate Adaptation in 2021: How Machine Learning and Earth Observation
are Key to Extreme Event Resilience
Abstract
The various extreme weather events that occurred globally in 2021, from
Europe to China to North America, served as yet another reminder that
robust strategies for climate adaptation are crucial at a time of rapid
global warming. Building resilient communities and lessening the impact
that natural disasters have on vulnerable infrastructure can be aided by
automated systems driven by machine learning algorithms trained on Earth
observation data. When deployed, computer vision models can analyze
satellite imagery in real time and inform decision makers and
nongovernmental organizations about the timely and targeted allocation
of resources and humanitarian aid personnel to affected areas. Here, we
overview several specific 2021 extreme events and the factors that
caused the loss of life, damage to infrastructure, and economic loss.
The events surveyed include flooding in Germany, wildfires in Greece,
and Hurricane Ida in the Eastern United States. Taking this information
into account, we further discuss barriers to the large-scale deployment
of current machine learning technologies, especially models trained on
Earth observation data. We examine the limitations of satellite imagery
and big data applications in detecting damage and building collapse and
how Interferometric Synthetic Aperture Radar (InSAR) can be a tool to
resolve existing issues. The aim of this work is to understand why many
state-of-the-art models being developed have not yet been successfully
and extensively deployed in the real world and to foster discussion
about optimizing the use of deep learning technology to save lives and
lead effective disaster management efforts.
