Forester City of Lorient, France

Reforestation of unused areas in the municipality of Lorient


Artisanal wood building and heritage conservation

The city of Lorient has developped an urban and local forestry partnership to supply the city in firewood chips and building timber. This project is based on local economy and on collaboration with local foresters to provide a sustainable management of this resource.

  • Local production of wood to supply (energy and building timber) the city of Lorient
  • Reduce the environmental impacts of importation
  • Foster the local economy
  • Enhance the city by using abandonned sites for logging
  • Trees planting in urban abandoned sites
  • Sites management and maintenance
  • Eco-sourced (wood) material povision for building

Global (estimated) cost of the project: 200k€- 1M€

Financing mechanism: cluster1 public financing

This project is based on local production of wood to supply (energy and building timber) the city of Lorient. It allows to reduce the environmental impacts of importation, foster the local economy, and also enhance the city by using abandonned sites for logging.

Expected time for the NbS to become fully effective after its implementation: medium (between 2 to 5 years)

FeedBack: still well adapted

Expected life time of the intervention: more than 30 years 

Dates (for project delivered): ongoing (2018)

Nature4Cities ( aims to develop a knowledge diffusion around Nature-Based Solution (NbS) and a decision support platform through new collaborative models.

This project is part of the Nature4Cities's pioneer case studies database, it will feed the observatory, NbS pre-selection and replication tools, gathered into the Geocluster4NBS.

This project was chosen as a pioneer case study for the following reasons: the project is a combination of local economy and hedge maintenance

Nature4Cities project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 730468.
