On Thursday November 24th the seventh edition of Cop47 “Meeting of Actors in Adaptation to Climate Change in the Southwest” was held. Water management and hydrogen interests were discussed during the morning.
During this week, 47 took place, at 47, the traditional meeting for reflection on climate issues, Cop47, led by our colleague Bastien Souberbe, from Sud-Ouest. This year, the event was held at Rosette Town Hall in Passage, and for the occasion, last year’s mayor of the host municipality handed the baton to an elected passer, representing Francis Garcia, currently in the conference’s mayors. “The witness sounds like a club, and the ideas must reach our heads,” Zlat amused the mayor of Saint-Hilaire-de-Luzignan where Cop47 2021 was held.
The two elected officials, after listing the achievements of their municipalities, agreed with Jean-François Berthomeux, for whom this annual meeting is an opportunity to take stock. “What did you do this year, and what are you going to do next year, I want you to go out and commit to actions,” he says into the microphone via an introduction. Ecological grazing, tree planting, photovoltaic roofs, methane production from sewage treatment plant sludge, gentle paths, the achievements are many, but we must go further.
By showcasing solutions selected in other communities or specifically developed by other companies, Cop47 hopes to inspire players in the Lot-et-Garonne field. The first speaker, Antoine Orsini, is a Corsican and … “schizophrenic”, as he puts it. “I am a scientist and an elected local official,” he specifies, a dual role that has enabled him to devise smart solutions to better manage water resources.
On his island, the Mediterranean climate forced the inhabitants to adapt, but he made it clear that in 10 years, we too would be on a Mediterranean diet, while Corsica would be tropical! At home, climate change is causing a huge discrepancy between extreme low water levels and catastrophic floods, so it is imperative to think about better water management. And between storage and economy, the chosen scientist decided. Bulk storage is not the answer in his opinion, and worse, it will help the development of harmful cyanobacteria.
On this specific point, Jean-François Berthomeux, the second speaker in this water debate, disagrees completely. The latter defend the new generation lakes, and are equipped with sedimentation ponds to prevent the spread of these bacteria. In Corsica this is monitored by drones, and here too technology is essential, in particular to monitor erosion risks. The extensive use of flood monitoring sensors is also a pioneer.
Solutions are there, it’s up to us to change the paradigm
The latter is joined on the stage of the Salle de Rosette by Bruno Caillet, curator of the Maison Forte de Monbalen whose innovations are there, it is the fantasies to be modified and this is not so easy. …a note shared by Nicholas Gent, Director of Sem Avergies. “We do not need a technological revolution, but rather a revolution in our actions,” he says, on the sidelines of his presentation of the various areas of his group’s work in the field of renewable energies. The reflection focused particularly on hydrogen and its interest and limitations.
Obviously the main reason is financial, but the question of its environmental impact also arises. That is why the arrival of Gérard Gat, president of Saquin, was relevant. “To produce hydrogen, we start from methane and methane, and all living things can produce,” he explains. An interesting introduction to wrap up this morning by thinking about adaptation to climate change.
