In Brittany, the public consultation preceding the development of a plan to combat nitrates did not reach the general public.
Only environmental associations and agricultural structures have given their opinion on this thorny issue.
The nitrate concentration in waterways is one of the major factors in the production of green algae.
It was to be the collection of the opinion of the Breton population on the delicate subject of nitrates, largely responsible for the proliferation of green algae. It ended in a usual battle of experts on the file, opposing environmental protection associations to the agricultural profession. Launched in the fall ahead of the revision of the nitrate control programme, the public inquiry was the subject of more than 500 contributions. If she welcomed the "high quality" contributions, the head of the survey deplored the absence of Mr. and Mrs. Everyone in the debates. "We haven't really gotten out of the insider circle," laments Sylvie Denis-Dintilhac. We have not been able to reach the general public. »
The one who officiated as guarantor of the National Commission for Public Debate seemed to discover "two antagonistic visions" on the place of livestock in Brittany.
Pointed out by environmental associations, the high concentration of farm animals is defended by a large part of the agricultural profession.
What do the 3 million people who inhabit the region think?
We won't know.
Note that if the subject of green algae is known to all, it remains eminently complex and difficult to understand.
“We keep concentrations high”
Summoned to act by the Court of Auditors and the administrative court, the State tried to defend the results of its sixth regional nitrates directive action plan, believing that “the situation has improved”. "We are not in the same situation as in 2014. But it is true that we keep high concentrations in several sectors", regrets Philippe Mazenc. For this seventh plan currently under discussion, the secretary general for regional affairs of the prefecture believes that "the challenge is to change agricultural practices": "We must try to reconcile economic performance and respect for the environment".
Since 1994, Brittany has been entirely classified as a "vulnerable zone" for the quality of its underground and surface waters.
In Ille-et-Vilaine, only 3% of surface water is classified as "in good ecological condition" by the Loire-Bretagne water agency.
The concern is particularly strong this year, especially in the bay of Saint-Brieuc, where the strandings of green algae have been massive.
Problem ?
They continue even in winter, traditionally a “quieter” period in terms of strandings.
The specialists are clear: it will take major storms to "disperse" the algae at sea and prevent the year 2022 from being black on the front of the green tides.
