Biodiversity is a key theme on which a municipality can act to strengthen its resilience in the face of climate change, reduce its greenhouse gas emissions and reduce the effects of heat islands in urban areas. Alterna can support the municipality in the development of a plan in favor of biodiversity.

This plan may include actions such as differentiated maintenance of municipal green spaces, the sowing of local species or even the reduction of pesticides and herbicides.

In addition, in order to promote food production for its inhabitants, Alterna can support municipalities in the creation of shared urban gardens, workshops on vegetable production in their apartments or even the promotion of the Garden Charter for individuals.
