The sediments accumulated in the Mequinenza and Riba-roja swamps would guarantee the survival of the Ebro delta for one hundred years, according to experts who have participated this Wednesday in a seminar on the future of the European deltas.

Experts have confirmed that the measures to send sediments to the Ebro delta, together with other short and long-term strategies, are essential to guarantee its survival. The head of the Eurecat Climate Change department, Carles Ibáñez, explained that the sediment retention in reservoirs in the Ebro basin is 99%.

“Maintain the delta 50 or 100 years”

According to Ibáñez, the arrival of sediments to the delta is fundamental: “Currently, the Mequinenza reservoir accumulates 100 tons of sediment at its bottom. While that of Riba-roja d’Ebre has a minimum of 20 tons. “With this storage it would be enough to” be able to maintain the Ebro delta for 50 or 100 years “, since its survival would depend on reaching its final stretch around one to two tons a year.

The arrival of sediments should be combined with other strategies, such as construction of dikes inside the bays of Alfacs and El Fangar or the contribution of sands in the outer zones that suffer directly the onslaught of the sea.

Common European strategy

The conference, entitled “The European Deltas against climate change”, has aimed to seek synergies with other European deltas within the framework of the common Green Deal strategy, promoted by the European Commission.

Diana Riba MEP has announced that “the first action” that will be promoted by the Green / ALE group “will be make a common front with the drafting of a manifesto addressed to the European Commission “, endorsed by MEPs linked to territories with deltas and the NGOs of the territory, to expose “shared problems, particularities and possible solutions”.

For its part, the Platform in Defense of the Ebro, through one of its spokespersons, Matilde Font, has shown that “The Ebro delta is one of the most threatened deltas, but it is also one that can be saved if there is political will“Dagmar Kalajarikova, the head of EU Water Policy and Legislation, also spoke at the conference and outlined the objectives of the European Green Pact.
