A study conducted by experts in ecology, marine biology and engineering from the University of Girona, the Polytechnic University of Catalonia (UPC) and the Institute of Marine Sciences (ICM-CSIC) concluded that the marine wind park is intended for golf. of Roses would harm the ends 135 vulnerable species, Some of them play a crucial role in the environmental status of marine waters.
Among these species there are marine mammals, such as the bottlenose dolphin; aus marines, with the Balearic baldriga and the black-capped gavina; elasmobranchs, like the tintorera or tauró blau, and benthic macroinvertebrates, like sponges and mol·luscs. Among the stress factors identified is the soroll, the vibrations and the loss and the damage to the habitat.
The team of scientists has analyzed for the first time the possible effects of this technology on the marine biodiversity of the Mediterranean, focusing on the projects planned in this area. The results have been recently published in the scientific journal
Sota the title Assessing the Potential Impacts of Floating Offshore Wind Farms on Policy-Relevant Species: A Case Study in the Gulf of Roses, NW Mediterraneanthe article highlights the need to balance the decarbonization with the preservation of marine biodiversity.
Environmental stress factors
The sample studied is included in the national species protection catalogs of the Habitats Directive and the Aus Directive of European regulations and the Green List of the International Union for the Conservation of Nature (IUCN), and in the international conventions for to the protection of the flora and fauna of Barcelona, Bern or Washington.
The first phase of the study consisted of identifying and evaluating the main environmental stress factors associates with the floating marine wind farms. According to lloc, using the Generalized Impact Assessment methodology, the impacts of these factors on sensitive species will be evaluated to take into account the temporal and spatial extension of the stress factor and the sensitivity of the species to each factor.
Finally, it is going to identify how the technologies proposed in the different projects of floating wind farms in the research area are related to the pressures that affect the species studied.
Collect data ‘on site’
In this sense, the study underlines the need to collect more information on sitefor species-specific studies and analysis of existing ecosystems to better understand the effects of floating wind farms on marine biodiversity.
The research group also concluded that it is essential to avoid these impacts to balance the decarbonization of the economy with the preservation of marine ecosystems and, especially, areas of high biodiversity such as the Golf de Roses and the Cap de Creus.
The research is part of the BIOPAIS project, coordinated by the UdG and the ICM-CSIC, with the support of the Biodiversity Foundation of the Ministry for the Ecological Transition and the Demographic Repte (MITECO) within the framework of the Recovery, Transformation and Plan. Resilience (PRTR), finance for the European Union-Next Generation EU.
