The enormous balance of Danys from the DANA country through various parts of the Iberian Peninsula -amb special virulence to the Valencian Country, as the storm has caused deaths – Damunt la taula has returned to pose need to prepare to face episodes of this type. Although it is unfortunate that storms that generate major floods are relatively common in the Mediterranean climate, all scientific evidence shows that as a result of climate change they will increase in intensity with each storm.
In this sense, the consulted scientists are clear that the road would have to pass through plan and execute “adaptation” policies to the climate emergency. Among other questions, these are intended to cause profound changes in urban planning and, in certain cases, involve the transfer of railway lines, the reform of maritime passages and, ultimately, the demolition of buildings in the riskiest areas. The flood, the entrance, no time has ever been built.
The DANA of this week is just the first example of a debate that is about how there is a storm that causes deep dangers, as will also happen from fortunately men and women death cases such as freda drop that will colpezar the Terres de l’Ebre the setembre de l’any passatthe storm Glòria of 2020 or the storm Filomena of 2021.
Scientists defend the need to plan and implement “adaptation” policies to the climate emergency
But finally it is nothing more than a “dynamic reaction” to the events [meteorològics]sense that the planning has varied by the administrations”, points out Carles Ibanezscientific director of Center on Climate Resilience (CRC), a space dedicated to promoting research and innovation in adaptation to the climate emergency.
Deixar espai to the water
For Ibáñez to rethink the coast, which may be affected both by floods coming from the continent, by the landslides that arrive from the coast and by a rise in sea level that is accelerating. But also “The countries of rivers and rivers, because they have little space to evacuate the water“When, because of a storm, they experience sobtats creixements. “We have to rethink the territory and apply the perspective of the horizon of climate change, which accentuates extreme phenomena“, says the direction of the CRC, a project promoted by the Eurecat technological center, together with the Rovira i Virgili University (URV) and the Amposta City Council, at its location.
In this sense, the scientist sees it as essential that the administrations “assumeixin with a high-level transversal objective to try to anticipate part of these danys“Provocated by extreme meteorological phenomena, which implies “planning short, medium and long-term measures”. Deixen rivers, rivers or torrents without a natural space that recovers both because there are floods. Certain canalizations or a good part of the sea passages also limit the space of the crescuda of the water, following a river or the sea in the cas d’una carried.
For Carles Ibáñez, adaptation policies must be “most local”, since “he who serves a municipality does not serve another”
The scientific director of the CRC highlights that there are “policies for adaptation to climate change”, but he points out that it must be a “most local adaptation”, since “he who serves a municipality does not serve an other.” “There are some general principles and from here on there is a very detailed coneixement of the terrain in order to make the adaptation effective. “I don’t have a bad adaptation, which makes it even more difficult to face,” he relates. For example, “we will try to find out how it will be inevitable to demolish buildings, where it will be possible to regress the sea passages so that they can be sustainable or move infrastructures.” .
What is one bad adaptation? Doncs qua “the only thing we can do is rebuild the infrastructures that have cost a floodHowever, it is essential to carry out a prior analysis to identify the “critical points and think about the redesign of urbanism and infrastructure to adapt to the new situation.” .
“The clau is in guanyar space of accommodation, both on the coast and in the river bank, so the water and the sediments can flow”
“The clau is in guanyar espai d’acomodació, both on the coast and in the valley of rivers and rivers, because the water and the sediments begin to flow” without causing great dangers, he continues. Ibañez places the focus on the fact that it is imperative to “redesign the uses of the territory so that they remain more compatible” with some phenomena that go further and, therefore, “anticipate what will also happen.”
“For example, we have to leave space to the sea, because it will also create,” he points out, which involves extending the beaches. About això hi incideix també David Pinoprofessor of the Physics department of the Polytechnic University of Catalonia (UPC), who reiterates “A beach with greater amplitude is better able to dissipate the energy of the waves. “and the pressure of the sea level, which acts as a natural defense mechanism for the coast.”
Pine is also MEDIFLOOD project coordinatora catalog that records 14,500 cases of pluvial and fluvial flooding on the peninsular Mediterranean coast during a millennium and that allows us to see the effects of urbanism due to natural phenomena in order to be able to prevent them with the best guarantees.
Urban planning in flood zones
In the concrete case of Catalonia, 15% of the urbanized surface is troba in a flood zone, whether river or maritime, according to theRiskCat reportwhich is responsible for evaluating the cliffs of natural phenomena. The Baix Ebre and the Montsià -the two regions where the Delta de l’Ebre is located-, parts of the Maresme and La Selva coast -above all the final tram of the Tordera, between Malgrat de Mar and Blanes-, the most appropriate areas The Llobregat -especially the Delta- and the Besòs of the metropolitan area of Barcelona, parts of the Alt Empordà and areas of the city of Lleida or Girona are among those with the highest flood risk, also partly because the majority have a raised level of urbanization.
According to Carles Ibáñez, això “és a mortgage that arrosseguem of the past decades, when it is going to be built in areas where there is no time to have fet“I, therefore, would have to “rethink planning” in the areas of greatest risk and “refer infrastructures to the extent that they create opportunities.”
“We know that these phenomena [extrems] They will continue passant i, per tant, ins hem de fer the question of what volem fer”
In one previous interview with this newspaperDavid Pino argued that “we know that these phenomena [extrems] They will continue passant i, per tant, ins hem de fer the question of what volem fer. Continuing is an investment to try to promptly alleviate the effects of a flood and return to the previous situation? Or is there a larger investment in which areas we can save that floods have affected the population? Why If I haven’t seen any, the impact is much smaller“. A reflection fully valid these days.
Amb tot, Carles Ibañez asserts that “the economic actors themselves have seen that this is an opportunity for a more humane, habitable and well-designed urban planning, which deixi enrere what is going to be designed in a chaotic and highly disordered manner for the rest of the year. 60 i 70” of the second passat.
“If we do not anticipate the problems we will end up paying more in economic costs, but also in human lives”
Or, finally, decades ago, as is the case of the R1 line of Rodalies, which passes along the first line of the coast of a Maresme with some beaches that have anat perdent gruix and that, according to it, s’hauria of “move cap to the interior.” “Tothom know that cal fer-ho, but it is not a priority with the investment. We are not directing resources cap to these questions, which are priorities, and as later it will be better.” As a final note, the scientific director of CDC concluded that “if we do not anticipate the problems, we will end up paying more in economic and infrastructure costs, but also in human lives.” Com, unfortunately, s’ha vist al País Valencià.
