What to do with industrial wastelands and disused agricultural buildings in Brittany?

Brittany, a region historically characterized by strong industrial and agricultural activity, is today faced with a growing number of brownfield sites and disused agricultural buildings. These sites, often abandoned, represent a challenge in terms of land use planning, environmental preservation, and economic revitalization. However, they also offer considerable potential for innovative and sustainable conversion projects.

State of brownfield sites in Brittany

In Brittany, deindustrialization has led to the closure of many production facilities, leaving behind often polluted and underutilized brownfield sites. According to available data, the region has supported 50 new brownfield recycling projects as part of the France Relance plan, which aims to rehabilitate these sites for new uses.

At the same time, the Breton agricultural sector, while still active, has seen a reduction in its activity in certain areas, leading to the decommissioning of agricultural buildings. These structures, often old and sometimes polluted, require specific interventions for their conversion.

Challenges of reconversion

Environmental

Brownfield sites and abandoned agricultural buildings can present environmental risks, such as the presence of pollutants (asbestos, hydrocarbons, heavy metals). Remediation of these sites is therefore a crucial step before any reconversion.

Economical

The conversion of these sites requires significant investment.

However, it can also generate new economic dynamics, creating local jobs and attracting new activities. For example, the project to rehabilitate a brownfield site in Loudéac aims to create housing and businesses, thus contributing to the revitalization of the town center.

Social

The reconversion of these sites can meet local needs, such as

creation of housing, public spaces or services. It can also strengthen social ties by reintegrating these spaces into community life.

Examples of successful reconversion

The Rosporden project

• The Minez industrial wasteland has been rehabilitated into a residential area, allowing the construction of housing and the revitalization of the district.

  
  

The Lamballe project

• Eleven disused agricultural buildings were removed from asbestos and rehabilitated to allow temporary re-cultivation, thus eliminating the risks of fire and intrusion.

  
  

The Flax project in Finistère

• Brownfield sites have been rehabilitated to revive flax production, thus revitalizing the local economy.

Perspectives and recommendations

To encourage the reconversion of brownfield sites in Brittany, it is recommended:

• To encourage public-private partnerships : Local authorities, businesses and associations must collaborate to define the projects best suited to local needs.

• Facilitate access to financing : Mechanisms such as the France Relance plan or regional aid can financially support reconversion projects.

• To implement appropriate planning tools : Urban planning documents must integrate the reconversion of brownfield sites as a priority objective, by defining specific zones and simplified procedures.

In conclusion, brownfield sites and disused agricultural buildings in Brittany represent both a challenge and an opportunity. Through a concerted approach and targeted investments, these sites can be transformed into assets for sustainable development and the revitalization of Breton territories.
