Visualizing complex risks for informed action

The links between environmental change, climate stress, conflict and the vulnerability of populations are complex, and access to data on these subjects is not straightforward. The result of a collaboration between Earth Blox, the United Nations Environment Programme (UNEP) and the University of Edinburgh, Strata brings together data from a variety of sources to see and locate 'hotspots' - those areas most at risk.

Preserving the bocage network

Hedgerows are excellent levers for the resilience of territories to climate change and for maintaining biodiversity. EagleHedges has developed operational tools for monitoring and characterizing the bocage network using Earth observation images and very high-resolution 3D models, in order to make up for the lack of reliable, recurring data on the state of the French bocage. The project team is working to extend the tool to other territories and, as new needs arise, to extend its functionalities.

🟢 HedgeTools, the hedge characterization tool, is available as an open-source QGIS plugin.

🔵 Automatic hedge detection service available on request.

Identify and visualize agricultural wasteland

The Izifriche solution is a comprehensive support service for the identification and visualization of agricultural wasteland, aimed at local players wishing to act for the resilience of their territory.

Developed as part of the SCO FrichesAgricoles project, the method for automated identification of wasteland is based on the use of geographical and satellite data analyzed by the WaSaBI ©CNES software's Artificial Intelligence, at the scale of the entire Occitanie region (France). The parcel data from the regional inventory of wasteland is used in a web interface equipped with numerous geographic databases, providing a global vision of the issues at stake at different territorial scales (commune, inter-commune, département).

🔵 Service marketed by Safer Occitanie from June 2024.

Thermography of cities from space

A pioneering project to learn how to use satellite thermal data in cities, Thermocity has delivered a collection of analysis-ready-data thermal images. This collection has been used to generate 4 major product families:

• Evolution of impermeability/artificialization and characterization of vegetation in the city;
• Detection and characterization of thermal anomalies;
• Mapping urban heat islands and diagnosing vulnerability to the associated heat ;
• Urban climate modelling: cross-validation and future climate.

Estimating coastal flooding

Created by CLS to help coastal areas reduce their vulnerability to rising sea levels, the interactive LITTOSCOPE interface allows users to visualise several scenarios of rising sea levels, with or without a ten-year storm.

The tool also offers an assessment of the impacts (human, economic, heritage, environmental) generated.

🔵 A commercial service, access to Littoscope requires an account and password.

Monitoring cyclonic impacts in the Indian Ocean

Cimopolée is an interactive web mapping service for monitoring the impact of cyclones in the south-west Indian Ocean. Clear and intuitive, the tool displays the presence and trajectory of a cyclone in the OI zone in real time and provides more comprehensive information on the major cyclones of the last ten years. The data and associated background information can be downloaded for more detailed analysis using GIS or statistical software.

Coastline monitored by satellite

Littosat distributes seasonal image mosaics at high and low tide, systematically and at high spatial resolution (10 m). From these data, it generates high value-added products on foreshore vegetation, and will soon offer products on submerged vegetation and foreshore morphodynamics, feeding seasonal change detection functions on a regional scale.

3 interfaces are online: Littosat Brittany, Littosat Normandy and Littosat Gulf of Lion

Identifying the vulnerability of urban environments during summer heat waves

Developed in the cities of Lille (France) and Rayong (Thailand), the project has established a methodology for classifying local climate zones derived exclusively from very high-resolution satellite images.

The issues identified are the vulnerability of urban environments during summer heat waves, and the adaptation and mitigation of local heat peaks.

🟢 The application's coding is open-source on Cerema's github and can be transposed to any city. Shapefile files for Lille and Rayong are available to download in the Resources section of the project page.

Monitoring tropical deforestation

The Tropisco platform provides a near-real-time view of tropical deforestation from 2018 to the present day. Its maps of forest cover loss are updated every 6 to 12 days using radar images from the Copernicus Sentinel-1 satellite.

Aiming for global coverage, Tropisco currently monitors the forests of 7 countries (French Guiana, Suriname, Guyana, Gabon, Vietnam, Laos and Cambodia), which were used to develop the tool.

Monitoring territorial dynamics

Developed in the Mato-Grosso region (Brazilian Amazon), the Chove-Chuva demonstrator offers a map-based summary of the territorial dynamics observed in relation to the adaptation and mitigation strategies put in place.

Using multisource data, the tool can produce a 'dashboard' of the territorial situation for an area predefined by a user, based on synthetic indicators covering 4 major themes: climate (rainfall), forest cover, water (hydrology) and agriculture (surface area and practices).

Improving coastal governance

Developed by the company BlueCham on Tahiti and a Tuamotu atoll (Tahatai project), the QVX-PF platform offers new digital resources for the governance of the coastal zone, a privileged place for exchanges between land and sea parties. The interface displays three indicators: water quality, anthropogenic pressures in the lagoon environment (including automatic boat detection) and anthropogenic pressures on the coastline (land use).

Development is continuing through the Tahatai Neo project to deploy the system throughout Polynesia and then internationally.

🔵 Commercialised service, access to QVX-PF requires an account and password.

Supporting solutions based on urban vegetation

Supported by Cerema, the GUS project has developed a method for fine mapping urban vegetation in order to better assess its many ecosystem services. The results obtained in Greater Nancy are available online on the Landia platform (ex Green City) operated by TerraNIS. This platform offers summary indicators at different grids (hexagonal, urban morphological island, IRIS, municipalities, etc.), data explorers and summary dashboards.

🟢 Access to the Nancy demonstrator is open.

🟢 Based almost entirely on THR satellite images, the method can be replicated for any town => the algorithmic codes are available on Cerema's Github.

Assessing the vulnerability of coastal populations and economic activities

Developed for the city of St Louis in Senegal and replicable for other coastal areas, the SCO St Louis interface combines all types of data to estimate the socio-economic vulnerability of coastal cities to the effects of climate change and raise awareness among local players.

The mapping platform can be used to select and combine several layers of information, including historical floods, land use and essential infrastructure, as well as simulations of marine and river flooding according to different IPCC scenarios.

Improving resilience to extreme hydro-meteorological events

Developed as part of the FLAude project, FORO uses satellite observation to improve the resilience of areas to the risks of flooding caused by intense run-off.

A genuine decision-making tool, FORO offers interactive maps to pinpoint problem areas and the levers for action. FORO is gradually being rolled out across the 23 departments of the Mediterranean Arc.
