Asian algae are becoming a huge problem

In 2019, someone from the Tarifa City Council had The idea of ​​moving Asian algae (Rugulopterix Okamurae) that accumulated on their beaches to a landfill near the water treatment plant. It was an effective idea. Until it ceased to be. Today, They recognize that “they no longer know what to do.” They have a problem of more than five million euros that does not stop becoming more and bigger. And rate is just the best known example. Only “15,000 tons are collected in Ceuta. Antonio Vegara Jiménez said in Newtral. Despite all efforts, last year invading algae They started arriving in Galicia. That is, the thing gets serious. An ecological, economic and social problem. Every summer, millions of people approach the coast looking for sun, good weather, crystalline waters and clean sands. And it is increasingly difficult to find it. Instead of a beautiful Mediterranean beach, which are usually increasingly tourists and locals is that brown, viscous and smelly mass left by the “invading algae” when dying. In Spain, it is not necessary or remember, the beaches are A huge economic resource. At the tourist level, but also at the fishing level. Algae are threatening Some of the country’s main industries And the truth is that the coordinated response shines for its absence. For more than a decade, each town hall has made the war on their own and, let’s be honest, they are losing it. But why they are so dangerous. By its extraodinarily aggressive behavior. This species grows very fast, is very versatile and has almost no native predator. Therefore, it displaces native algae, drastically reduces biodiversity and cause innumerable problems for artisanal fishing, aquaculture, tourism, the funding of vessels and municipal management (that brown mass has urban waste consideration). How have you get there? In 2002 they began to see in France and for 2015, they were located in Ceuta. Possibly, it was due to merchandise ships, a well -known vector of invasive species. From there, its expansion has been rapid: first the Gibraltar field, then Málaga, Granada, and now other coastal regions. And what can we do? That is the worst: there are no miraculous solutions. Marine biologists warn that, once an invasive species is established and finds favorable conditions, eradicating it is almost impossible. Therefore, many researchers and businessmen They are starting to make the need virtue and seek to turn it into a resource (something that would help finance its management). But for now the situation leaves much to be desired. It is not the end of the story. Because what we are seeing with the Rugulopteryx Okamurae It is not exactly an isolated phenomenon. Em Mediterranean is changing and we don’t know where it will take that. Every year, driven by climate change, maritime traffic and alteration of marine ecosystemsS, more invasive species find a new home on the Spanish coast. With the economic and ecological future of our coastline, the most desperate thing is that the evidence tells us that we have no administrative instruments to face this problem. And when we decide to take action on the matter, it will probably be late. The safest thing is that it is already.

Rate has more than 40,000 tons of algae and does not know what to do with them. So you will try to monetize them

Desperate and without knowing very well what to do, the Tarifa City Council began to transfer Asian algae (Rugulopterix Okamurae) that they were invading their beaches in a landfill near the deputy of the municipality. It was 2019. Since then, 40,000 tons have accumulated and, like They themselves recognized in October“They don’t know what to do.” The landfill begins to stay small and the cost of treating all that huge hill of algae exceeds five million euros. Something that the Cadiz Consistory cannot afford. Therefore, for months, they ask that some administration help them out of that dead end. Without much success, really. But what do so many algae do there? Is it normal? It depends on what we understand as normal: the Rugulopterix Okamurae It is an invasive plant And, therefore, it is not a traditional problem. However, in recent years, its impact has not stopped growing. That is an ecological problem (they reduce the biodiversity of each place they arrive), economic (prevents fishing) and aesthetic (produces damage to tourism). But it is also a waste management problem. Because, when they pile up on the beach, they become urban waste. And accumulate wildly. To put figures, “only in Ceut Antonio Vegara Jiménez said in Newtral. Now they have had an idea. And, tired of passing the ball from one another, the City Council has approved the installation of an experimental bioreactor of a Valencian company (Poplac Development) With the idea of ​​testing if it is viable to convert that mountain of waste into a mountain of money. Money? Well, if we want to be precise, it would be in a “mountain” of biogas, electricity and fertilizers. But yes, in general terms, it is about testing if the “public-private collaboration” can give an exit to all that biological material that accumulates near the Strait. As explained in the economistthe installation that PLACAC DEVELOPMENT prepares could generate a megavatio room for every 15,000 tons. And, in addition, produce fertilizers for agricultural use. And will it work? Well that is the big doubt. From what we know, there are already projects like this in Mexico and it seems that the results are good. But the sector is very incipient and regulation is very different in Europe. However, there is something clear: something must be done. The invasive species They are the order of the day And if we do not look for solutions, we will have many more problems than a landfill with 40,000 tons of algae rotting.
