Space observations for monitoring coastal hazards

Convener: Yannice Faugère | Co-convener: Anny Cazenave

Wed, 04 Jun, 12:45–13:45 (CEST)|Room 3

The world coastal zones are suffering numerous hazards of natural and anthropogenic origin. These include climate-related extreme events, sea level rise and ground subsidence, causing temporary and permanent flooding, coastal erosion and retreat, aquifer salinization, loss of biodiversity, etc. With the development of a large variety of advanced sensors aboard satellites, and the growing amount of available data, space-based Earth Observations (EOs) are increasingly being used to better support hazard monitoring, mitigation, adaptation and risk management. The EO datasets provide human society with the benefits of a synoptic view of natural hazards and their associated risks. The purpose of this Town Hall is to bring together scientists and stakeholders from different horizons involved in different aspects of coastal geohazards and their impacts on society and the environment, and exchange about the benefit of using Earth Observation data to monitor coastal changes due to natural phenomena and anthropogenic forcing factors as well as associated impacts on populations, environment and infrastructures. Gaps in knowledge and in observational systems will be identified and perspectives of improvement will be discussed. Another objective is to address opportunities of collaborations between the international scientific community, local research institutes, national and intergovernmental agencies, and the private sector for developing a global effort directed to monitor changes affecting the world coastlines and the associated risks, using a broad variety of space observations -combined with in situ data where available and high-resolution modeling-. Such an ambitious programme would be an invaluable first step towards mitigation and adaptation.
