C-RISe Project

NOC logo C_RISe

C-RISe (for Coastal Risk Information Service) will deliver, through an international partnership with Mozambique, Madagascar and South Africa; access to satellite-derived data on sea level, wind speed and wave heights. The goal is to enable stakeholders to use this information to improve socio-economic resilience to coastal hazards associated with sea level changes such as inundation, floods, storm damage, wetland loss, habitat change, coastal erosion and saltwater intrusion.

C-RISe is a development of Sea Level Space Watch (SLSW), a project funded by the UK Space Agency (UKSA) under the International Partnership Programme, which delivers information on sea level trends at the UK coast, enabled by recent advances in coastal altimetry data processing. C-RISe will expand this service to provide additional data sets (wind and wave climatologies), and increased temporal and spatial coverage; 24 years of previously unavailable satellite observations, over the regional area of Mozambique, Madagascar and South Africa.

Project impact will be assessed using a pre-identified set of use cases, each led by a different project partner, and through the delivery of hands-on training and use case coaching. This is designed to embed the skills needed to work with satellite data into the partner organisations for the long term. C-RISe will demonstrate the value that satellite data can bring to regions with sparse in-situ observations, and provide the skills to adopt space technology for more effective coastal management and positive socio-economic development. Project funded by UKSA under the International Partnership Programme (IPP).

PASS-SWIO: PASS-SWIO is a project building on recommendations from C-RISe and funded by ESA under the ESA Science for Society programme, which aims to establish a sea level monitoring system for Madagascar based on the installation and deployment of a low-cost relocatable tide gauge (Portagauge). More details can be found on the PASS-SWIO project web page

C-RISe Madagascar Workshop

C-RISe held an end-of project workshop in Antanarivo Madagascar, on 11-12 February 2020. The C RISe team was pleased to welcome 45 participants to the workshop, which reviewed the project and discussed coastal risk priorities for decision makers; how satellite data can complement other data sources to address priorities; and how to increase local capacity to use satellite data in providing scientific support in strategy development and management of coastal areas. The Workshop report is available here
