Biodiversity : 5 Priority Actions to Combat Invasive Alien Species

by Aurélie Vedel

IAS : a global phenomenon, a local challenge for companies Invasive alien species (IAS) are a recognized threat to natural habitats. They are the fourth leading cause of biodiversity loss worldwide. Their presence causes exorbitant damage to agriculture, fisheries, the environment, and public health. In March 2021, researchers from the CNRS published a summary of the economic costs caused by the presence of IAS worldwide. Between 1870 and 2017, the damage is estimated at 1.288 trillion U.S. dollars. This global challenge translates into a local struggle for ECT. The initial abandonment of most of the sites where we operate facilitates

Climate and Ecological Transition in Local Communities : Working with Local Governments

by Sophie Alix

The climate and ecological transition of local communities is not merely a matter of principles: it is built in concrete terms through development projects capable of turning environmental constraints into opportunities. Through its initiatives, ECT works on the ground to rehabilitate brownfield sites and support local communities in creating spaces that are more sustainable, resilient, and useful. The climate and ecological transition cannot be imposed by decree. It is built on the ground, project by project, through planning decisions that address climate challenges, biodiversity issues, and the new uses of sites slated for redevelopment. Transforming abandoned land and brownfields into

What if the biggest ecological problem were forgetfulness ?

by Guillaume Lemoine

In 1962, Rachel Carson’s famous book *Silent Spring* was published. It raised awareness among the general public and elected officials in both North America and Europe about the devastating effects of DDT use, which was driving birds from our countryside—both through poisoning and by disrupting their reproduction. DDT was subsequently banned. Today’s situation is much worse than that of the 1960s. The climate crisis, which is just as serious, overshadows the crisis of biodiversity loss, even though healthy ecosystems and soils would make our regions more resilient. Thanks to conservation and monitoring programs, a few major and iconic species are

Preserve bees in France: a major ecological challenge

by Guillaume Lemoine

Protecting bees cannot be limited to installing beehives for honey production—hives that most often house “Italian” bees or “Buckfast” hybrids—on the roof of an administrative building in the heart of an urban area, or to setting up an insect hotel in the middle of a carefully maintained green space. The priority must be to preserve wild species and their natural habitats. 960 species of bees, 80% of which nest in the ground. As we know, bees play a crucial role in the reproduction of entomophilous flowering plants. They also contribute to the production of fruits and vegetables. Above all, along
