Sustainable construction
SEED’s actions are organised around two main areas: support for eco-construction to improve housing and community spaces, training, and consultation and awareness-raising to strengthen the skills and capacities of local communities. Sustainable construction is therefore at the heart of the association’s mission.
In the case of the ‘Kër Alaam Gi’ project, supported by the setec Foundation, construction is being carried out using bio-based materials, in particular typha.
Typha australis is a reed found in abundance in the Senegal River and Lake Guiers. Following the poorly maintained hydro-agricultural developments of the 1970s, typha proliferated to the point of destabilising the natural balance of the water bodies. It is now so prevalent that it is a threat to ecosystems and has an impact on water quality.
However, this plant has qualities that are not to be underestimated, and it can be used in many fields, including construction. This reed can be put to good use in construction thanks to its hydrophobic properties. It can be used for wall insulation, roofing, sound absorption, etc. The construction of the Maison de l’environnement is being supervised by an architect specialising in the design and construction of bio-sourced buildings.
