The completion of the initial dam project Sivens is ” out of date “, announced the Minister of Ecology, Segolene Royal, Friday, Jan. 16. But how then bring water to farmers in the Tescou Valley, in the Tarn, and especially in what quantity? To answer these questions, the Minister of Ecology has received a report that two experts Forray Nicolas and Pierre-Alain Roche, advocate a solution that would provide them two times less than what they hoped to achieve dam Sivens .
For cons, the two authors have failed to reconcile the positions of agricultural organizations and organizations of environmentalists, and could not therefore draw the “project territory” consensus that M me Royal was calling. Although the actors on site could not gather around the same table, the minister has nevertheless welcomed in a statement the tracks outlined in the report. These could “ secure water requirements ‘,’ meet the objective of achieving good water status in respect of public financial rules “and would” obtaining European funding . “
It also refers the ball General Council of the Tarn, to organize a debate on Sivens end of January . Nevertheless, the government has not finished with this high-risk issue since the death of the young opponent Rémi Fraisse, October 26, 2014, during clashes with security forces. He will have to decide between two very different scenarios, under the watchful eye of the European Commission, which has launched an infringement procedure against Paris. Because the initial draft of the reservoir – large enough to store 1.5 million cubic meters and destroyed 13 hectares of natural wetlands – contravened the provisions of the Directive on water. A fault even more annoying that the investment should be based on a third of EU funding

After assessing the needs on the ground, the report’s authors conclude that, within 10% and with some effort to save water, a reserve of 750,000 m 3 should suffice, including 560,000 m 3 for farmers and 180,000 m 3 to support the flow of the river in the summer. Impossible for it to do without new dikes, they say. The experts are considering whether to install a tank size reduced to Sivens, 330 meters upstream, which would save 7 hectares of wetlands, or to use a set of more modest works a dam: a reservoir 300,000 m lateral 3 , supplemented by two or three hillside reserves (which essentially fill with rain and runoff).
The second solution should appeal to environmentalists, since it respects the environment. However, it is more expensive, more complex and requires to acquire new agricultural land, note the rapporteurs. While the former seems more likely to coax agricultural officials but involves paying more to compensate for the destruction of wetlands.
Warnings
Experts multiply warnings: can not “artificialize” more Valley Tescou or to develop the major irrigated crops. They also care about the forest cleared last fall. However, we would not be surprised to learn that their favor is the dam, cheaper and simpler to manage as long as operators agree on the distribution of the resource.
Their findings should be presented Monday, January 19 in the Tarn, where the climate has not improved. After a failed attempt to bring together stakeholders at the same table, it appeared that the Departmental Federation of Farmers’ Unions (FDSEA) Local (main agricultural union) would yield nothing on its initial dam project. In December, she wrote to Ségolène Royal it would use “ any other form of industrial action to be heard” if necessary.
The fear of the Sivens case lead to other challenged has probably pushed intransigence. In fact, the report advocates to question “the coherence and continuity of public action across the Adour-Garonne basin.” The Regional Council Vice President Midi Pyrenees, Gérard Onesta (Europe Ecology Greens, EELV), also wants to put water management flat. He just got the creation of a special commission to open the site of a completely different magnitude.
“ Sivens played the role of detonator in a magazine overheated for years. It is the symbol of all that he must not do , says Gérard Onesta. There are twenty other dams in anticipation, it’s time to raise the issue. Our representative commission of the regional council elected will launch a series of hearings by the end of January “The elected ecologist, who is familiar with the problem of water Adour-Garonne sums.” We have a total storage capacity of 3.3 billion cubic meters. Thereupon, 1.1 billion cubic meters goes to 30,000 farmers irrigate two thirds cultivate maize. “
However, the South West is prepared to change the model? The revision of the schema master development and management is ongoing and which should lead in the spring, will give some answers debut
