One of the greatest challenges facing human society, the risk of future flooding, continues to grow due to climate change and increasing population pressures on deltas and floodplains. Adequate monitoring, improved management and the restoration of ecosystems and vegetated foreshores are urgently needed.

Coastal, marine and riverine ecosystems benefit society by delivering 'ecosystem services', like carbon storage, support for sustainable fisheries and acting as a protective buffer between the sea and the land. However, marine foreshores are not currently included in water safety assessments and in levee design, and river floodplains are only managed to maximise river discharge capacity.

Flood - Defence - Potential - Strategy - Flood

Nature-based flood defence has enormous potential as a sustainable and cost-effective strategy for flood and erosion risk reduction, but it is not widely implemented at present. This is because engineers need trusted and practical tools to provide them with quantitative information on key parameters and foreshore status before adopting a nature-based approach to flood protection.

To develop reliable tools, the EU-funded FAST project utilised the services of the Copernicus earth observation (EO) programme to determine the characteristics of vegetated foreshores and help harness their potential to reduce the risk of coastal flooding and erosion.

Project - Partners - Ways - Aspects - Wetlands

Project partners studied ways of measuring aspects of coastal wetlands from the air and space EO data. Project coordinator Dr. Mindert de Vries explains, "The aim was to acquire such data at the global level and determine the importance of coastal wetlands to society at specific locations in great detail as well as globally raising awareness of the importance of nature for flood risk reduction."

Know-how from a wide range of disciplines was brought together to develop the MI-SAFE open source open data package of services, which provides users with knowledge, data and modelling services. The main vehicle for accessing and demonstrating these services is the MI-SAFE viewer. "The viewer gives access...
