Coastline at the limit

The Catalan coast is overbuilt and densely populated, while the long-term effects of human intervention have altered the dynamics of its beaches. Action is no longer merely advisable, but a necessity

The authors argue for a change in the management of beaches to make them more resilient
The report stresses that the impact of climate change on the coast will also have an effect on coastal infrastructure
70 kilometres:
the approximate length of the Catalan coast, from Portbou to Cases d’Alcanar.
43% of the population
is concentrated in coastal municipalities, although they represent only 6.7% of the country’s surface area.
70 towns have coastlines.
They are located in the counties of Alt and Baix Empordà, La Selva, Maresme, Barcelonès, Baix Llobregat, Garraf, Baix Penedès, Tarragonès, Baix Camp, Baix Ebre and Montsià.

From Port­bou to Cases d’Al­ca­nar, Cat­alo­nia’s coast­line is some 580 km long, or 6.7% of the coun­try’s total sur­face area. It is also home to 12 of Cat­alo­nia’s 42 coun­ties and al­most half of the coun­try’s pop­u­la­tion (43.3%). These are fig­ures from the re­port ’Un litoral al límit’ (Coast­line at the limit),com­piled by the Ad­vi­sory Coun­cil for the Sus­tain­able De­vel­op­ment of Cat­alo­nia (CADS). The doc­u­ment con­cludes that pres­sure on the Cata­lan coast is un­sus­tain­able and that im­me­di­ate ac­tion is needed.

The di­ag­no­sis

Apart from the tem­po­rary wounds in­flicted by storms like Glòria (Jan­u­ary 2020) or rises in sea lev­els that cycli­cally af­fect vul­ner­a­ble coastal areas such as the Ebre Delta, re­cent fig­ures show that beaches have re­gressed sig­nif­i­cantly in the coast’s more ur­banised areas. In Mont­gat, for ex­am­ple, the av­er­age beach re­gres­sion rate is 7.5 m per year, a fig­ure that reaches 9.8 m in Badalona.

The Mediter­ranean sea is ris­ing at a rate of 4 mm per year, says CADS, and in Es­tar­tit, for ex­am­ple, it has risen al­most 10 cen­time­tres over the past 30 years. Only 20% of the Cata­lan coast has enough space to ac­com­mo­date this re­treat in the face of ris­ing sea lev­els, which global pro­jec­tions in­di­cate could be as much as a metre by the end of the cen­tury. There is a lack of data on deltas, but they are also re­gress­ing due to ero­sion and sub­si­dence. The Ebre Delta coast is re­ced­ing more than 10 me­tres per year, and the Llo­bre­gat Delta has re­treated al­most a kilo­me­tre in the past cen­tury. The pic­ture is not rosy, but what makes the fig­ures even more alarm­ing is that 59% of the first 100 me­tres of the coast is ur­banised, with 120,000 new planned homes on hold while the Cata­lan gov­ern­ment con­ducts a re­view of un­sus­tain­able land.

On its list of crit­i­cal points, CADS warns about the sur­vival of coastal habi­tats: 70% of species and 50% of the coastal and ma­rine sys­tem habi­tats cat­a­logued by the EU-spon­sored Habi­tats Di­rec­tive are in a poor state of con­ser­va­tion, with only 17% in a favourable state.

The re­port stresses that the im­pact of cli­mate change on the coast will also have an ef­fect on coastal in­fra­struc­ture, whether trans­port (such as the R1 Ro­dalies rail­way line), en­ergy, san­i­ta­tion or com­mu­ni­ca­tions. Ports are also lo­cated in areas vul­ner­a­ble to cli­mate change. Storm Glòria, for ex­am­ple, caused dam­age with an es­ti­mated cost of more than 75 mil­lion euros in re­pairs to ports, beaches and prom­e­nades.

The so­lu­tions

There is no magic so­lu­tion and the study ar­gues that what is needed most is a com­plete re­think of how to make the coast more re­sis­tant. The re­port’s au­thors ap­plaud the pass­ing of Law 8/2020 on the pro­tec­tion and man­age­ment of the coast and the land re­view being car­ried out by the Cata­lan au­thor­i­ties. Yet they also point to other tools that they argue would aid the cli­matic adap­ta­tion of the Cata­lan coast. They talk about the cre­ation of a Coastal Con­ser­va­tory as an in­stru­ment to allow the ac­qui­si­tion and pro­tec­tion of coastal areas, and the pro­mo­tion of spe­cific plans to re­store and con­serve the coast or man­age its tourism. They also pro­pose a pro­gramme of ur­gent ac­tion to adapt the cur­rent in­fra­struc­ture to cli­mate change and plans for the trans­for­ma­tion of urban areas, which they argue should be re­nat­u­ralised.

Cur­rent reg­u­la­tion

While the state con­tin­ues to have the say over is­sues of gen­eral in­ter­est on the Cata­lan coast, the Cata­lan gov­ern­ment ex­tended its own pow­ers with the pass­ing of the Coastal Pro­tec­tion and Man­age­ment Act in July 2020. Known as Law 8/2020, the new reg­u­la­tions re­quire ac­tiv­i­ties on the coast to be planned, aim to pre­serve and re­cover coastal areas, in­clud­ing their ecosys­tems and land­scapes, pre­vent and re­duce the ef­fects of cli­mate change, reg­u­late ac­cess to beaches and en­sure co­her­ence be­tween pub­lic and pri­vate ini­tia­tives.

Xavier Berga, head of Co­or­di­na­tion of Coastal, Rural En­vi­ron­ment and Moun­tain Ac­tions, stresses that it is a very am­bi­tious law that “has to be­come the road map for what must hap­pen on the Cata­lan coast in the com­ing years.” The hope is that local au­thor­i­ties will use gen­eral pa­ra­me­ters to man­age their own plans for the use of beaches and the coast: “Apart from the plans for the Maresme and the Ebre Delta, there is no co­her­ent plan­ning from the state and we want to fill this gap,” Berga says, who adds that the doc­u­ment is not bind­ing.

The law also pro­vides for the cre­ation of the Coastal Con­ser­va­tory. Berga ad­mits there are de­lays but says it is in­evitable. “We want the cre­ation and op­er­a­tion of this body to be very par­tic­i­pa­tory, both when choos­ing which prop­er­ties to ac­quire and when de­cid­ing who should man­age them,” he says. Move­ments like SOS Costa Brava have com­plained about the de­lays. “It’s not what we want,” says Sergi Nuss, who chairs the fed­er­a­tion of over 20 or­gan­i­sa­tions fight­ing to de­fend the Costa Brava’s land­scape and stop urban spec­u­la­tion. If the con­ser­va­tory were al­ready op­er­a­tional, then a pri­vate in­di­vid­ual’s pur­chase of the land of the for­mer US mil­i­tary base Loran in the Montgrí Nat­ural Park could have been pre­vented, Nuss says.

Land re­view

There is also the task of re­view­ing urban plan­ning in Cat­alo­nia, which in Jan­u­ary 2021 led to the ap­proval of the urban mas­ter plan (PDU) for the re­view of un­sus­tain­able coastal lands in Girona. Known as the Costa Brava Pro­tec­tion Plan, the re­view served to de­clas­sify land and pre­vent the con­struc­tion of 15,000 homes. Agustí Serra of the Gen­eral Di­rec­torate of Spa­tial Plan­ning and Ur­ban­ism talks about an un­prece­dented task that began in 2015, when it was de­cided to re­view the legacy of a very ex­pan­sive urban plan­ning model. First a re­view was car­ried out in the High Pyre­nees, pre­vent­ing the build­ing of 8,500 homes, and then came the Girona coast­line: “We’re not elim­i­nat­ing any build­ings. Al­though it’s a very ef­fi­cient and very am­bi­tious re­view, there are some lim­i­ta­tions, and what has been done is a task of fine surgery,” says Serra.

SOS Costa Brava cel­e­brates the ap­proval of the PDU, al­though they con­sider it in­suf­fi­cient, be­cause it still fore­sees the po­ten­tial build­ing of 30,000 homes. “Now is the time for local au­thor­i­ties to act, and the sooner they re­view their urban plans the bet­ter. We hope they will be brave and re­vise con­ser­v­a­tively,” says Nuss, who re­grets cases such as the one in Cadaqués, where the local coun­cil’s re­view of its urban plans to bring them into line with the PDU led them to keep plans to build up to 800 new homes, which Nuss says does noth­ing more than “dis­fig­ure the pearl of the Costa Brava”.

With the ex­cep­tion of the Barcelona coast­line, a sep­a­rate case, the same re­view of un­sus­tain­able land is un­der­way in the 41 coastal mu­nic­i­pal­i­ties. The ad­vance draft was ap­proved in Sep­tem­ber and the doc­u­ment is now being drawn up to re­view 335 spe­cific areas in 30 mu­nic­i­pal­i­ties where, under cur­rent plan­ning laws, 110,000 homes could be built. While wait­ing for the doc­u­ment to be pub­lished, build­ing li­cences have been sus­pended in 236 un­de­vel­oped areas that have al­ready been found to be un­sus­tain­able.

Raw ma­te­r­ial of tourism

To pre­serve the coast, huge amounts of sand are needed, known as the raw ma­te­r­ial of tourism. There are no beaches with­out sand, and reg­u­larly truck­ing it in is no long-term so­lu­tion. The CADS re­port says that be­tween 2002 and 2010, in an at­tempt to stop the ef­fects of coastal degra­da­tion of beaches, ap­prox­i­mately 775,000 m³ of sand per year were brought in, mostly to the beaches of Barcelona. De­spite the money spent, the prob­lem per­sists and the au­thors argue for a change in the man­age­ment of beaches to make them more re­silient with­out hav­ing to rely on these con­tri­bu­tions of extra sand. Xisco Roig is an ex­pert in the field. A doc­tor of ge­og­ra­phy and ge­ol­ogy, he is a se­nior voice in beach man­age­ment and es­pe­cially in the re­cov­ery and man­age­ment of dune sys­tems. “Beaches will never go away,” he says, adding that this does not mean that we can con­tinue doing what we have thus far - “which is noth­ing since the 1950s” - and con­tinue using them as just leisure areas.

“The beach is the most dy­namic and mo­bile sys­tem on the planet, even more than a river, which is a con­fined chan­nel. The prob­lem is that beaches have been des­ig­nated as a sum­mer ser­vice and not as a dy­namic all-year-round sys­tem,” ex­plains Roig, who is in charge of beach man­age­ment re­ports, ap­ply­ing sus­tain­abil­ity cri­te­ria, and, where pos­si­ble, dune re­cov­ery. “I pro­pose na­ture-based mea­sures with min­i­mal in­ter­ven­tion. Soft mea­sures that help nat­ural re­gen­er­a­tion,” he says.

The mea­sures he pro­poses take more time than ar­ti­fi­cial re­gen­er­a­tion, but are about re­vers­ing the in­ter­ven­tion­ist ac­tions that have bro­ken the nat­ural dy­nam­ics of the beach sys­tem over the years. “We’re treat­ing beaches like pub­lic squares, me­chan­i­cally clean­ing them, which is ab­surd and very harm­ful,” says Roig, who has worked in the Balearic Is­lands, the Caribbean, Va­len­cia and here in Cat­alo­nia. “My goal is to man­age beaches prop­erly and make them more re­silient,” he says.

There is plenty of work to be done by every­one. But there is also work to undo what has gone wrong in the past. The head of the Montgrí, Medes Is­lands and Baix Ter Nat­ural Park, Ramon Al­turo, is clear about the need for ac­tion to pre­serve the coast­line: “It is nec­es­sary to re­move cer­tain el­e­ments of human ac­tion, be­cause if noth­ing is done, in 15 or 20 years it will be flooded.”

Advising the government Unstoppable regression

In 1998, a parliamentary request led to a new environmental advisory council in Catalonia. CADS (the Advisory Council for Sustainable Development) is a strategic advisory body to the Catalan government in the area of sustainability based on consultation with renowned experts. The body, which reports to the Department of Climate Action, Food and Rural Agenda, prepared a first report on the state of the marine environment in 2019: A sea of change, which recommended sustainable management of the marine and coastal environment. The continuation of this work is the Coastline at the limit report, which was presented to the government in September and recommends integrated management of the Catalan coast.

In the Maresme area north of Barcelona, the problem is endemic. The beaches are in decline and the fact that they are confined by port structures and railway tracks limits any room for manoeuvre. The only action currently being taken is spending millions of euros on extra sand, which just ends up being washed away by the sea. Xisco Roig says that 1,800,000 m³ of sand were dumped on Catalan beaches In the 1990s. “Artificial regeneration has a maximum shelf life of 30 years, and then it starts to decline,” he explains. In 2015, the state authorities approved a strategic plan for Maresme that provided for 30 projects based on the artificial regeneration of the beaches. The first one, in the Maresme town of Premià, is still pending.

La Pletera: the de-urbanised urban development

It was supposed to become a kind of garden city on the Costa Brava seafront between Estartit and Pals, with a capacity for 12,700 inhabitants. The revision of the original general plan carried out by the first democratic local authorities downsized the proposal to 655 homes on the seafront for 3,000 people. The first residential block was built and the promenade and streets were redeveloped for future development. But that is far as the project ever went.

Today, far from what was originally planned, La Pletera has become a seven-kilometre-long natural beach with dunes that help protect wetland areas home to endangered fish and bird species, such as the Spanish toothcarp and the Kentish plover.

This re-naturalisation of this urban area only came about thanks to the economic crisis that followed the 1992 Olympic Games and the subsequent halt to building work. It is also down to the courage shown by the Torroella de Montgrí town council, which stopped the project and promoted de-urbanisation of the area under the European Union’s LIFE environmental programme, which ran between 2014 and 2018. Since then, the area has become integrated into the Montgrí, Medes Islands and Baix Ter Natural Park, which has continued to work on the restoration and recovery of the dunes.

“With the restoration of the dunes and the habitats that go with them, we have gained more than a metre of height on the beach in just five years,” explains Ramon Alturo, director of the natural park. Although there has been a 12-centimetre rise in the sea level since the 1970s, drone surveys conducted since 2016 show that the beach is recovering, while the work done to restore the dune system has earned the park the Climate Change Award from EUROPARC, the European network of natural parks.

Apart from the La Pletera urban development, in the southern part of the natural park, in the municipality of Pals, is still to be found what is left of Radio Liberty. The facilities that used to host the United States government’s anti-communist propaganda radio station that broadcast during the Cold War are in a dilapidated condition. The facilities are state-owned and a demolition order for them already exists, but the park authorities are concerned about preserving the natural environment that surrounds them. “Because it has been closed off, a very unique dune habitat has developed around it that should be preserved,” says Alturo.
