CONTEXT

Towards achieving zero
net soil sealing by 2050

Every year in France, 24,000 hectares of natural, agricultural, and forested areas are urbanized for housing, economic activities, or road infrastructure. The environmental consequences are severe, and soil sealing is now considered one of the leading causes of biodiversity collapse.

Regulations now require the renaturation of spaces where possible, and land use restraint has become a national priority. France has committed, under the Climate and Resilience Law, to achieving “zero net soil sealing” by 2050.

This land use restraint trajectory can only be achieved if territories adjust the pace of soil sealing by promoting sustainable development models: revegetation, redevelopment of brownfields and downgraded areas, densification…

OUR SOLUTION

Landia, a tool for
monitoring soil sealing

To support municipalities in implementing new regulations, we have integrated into Landia a solution that allows municipalities to analyze and monitor soil sealing through thematic maps and indicators.

By combining different data sources, we produce large-scale land use maps that provide an overview of soil sealing and offer territories a tool to monitor its evolution. Moreover, through thematic indicators at different levels of analysis (morphological block, hexagonal mesh, neighborhood…), Landia identifies areas with high levels of soil sealing, facilitating the implementation of targeted measures for their preservation or rehabilitation. Local decision-makers thus have a solution to help them make informed decisions regarding land use planning.

USE CASE

Cartovegetation: production and analysis of land use data for monitoring artificialization

As part of the Cartovégetation project launched by FNE Ile-de-France, TerraNIS enriched with land use data to study the artificialization of the territory. We thus produce maps which make it possible to draw up an inventory of the level of artificialization and to monitor its evolution over time. Different indicators of artificialization are calculated and mapped and make it possible to characterize artificialized surfaces and identify their land use class. This tool facilitates the implementation of strategies to preserve or rehabilitate certain areas of the region.

USE CASE

In partnership with BRGM, TerraNIS is designing a tool to control its territorial planning decisions

As part of a Cap Digital POC&GO challenge, funded by the BPI, TerraNIS was selected by the BRGM and its partners to design a prototype of an integrated decision support tool in order to compare various development options for the territory. This tool, called Saterre, makes it possible to evaluate the effects of a project on the environment, as well as the resources from which it could benefit, depending on its location. Saterre is a real diagnostic, evaluation, forecasting and decision-making tool for all urban development stakeholders.
