Cala Corb lesson and the danger to s’Altra Banda

Views: 249

Four years of paralysis for ignoring the environmental laws

In Cala Corb, on the southern pavement of the Port of Maó works for connecting the pavement with the Moll d’en Pons, have been stopped for four years.

The reason was that the procedure used by the Port Authority awarded work consisting of a cantilevered walkway and suddenly, without any formalities or prior authorisation, it was turned into a construction dock with dozens of trucks emptying rocks into the sea.

A cantilevered walkway attached to the rock-face has hardly any effect on the marine environment, but, obviously, tons and tons of rocks being poured into the sea will transform its environment radically.

Any land subject to European laws, for some decades past, before causing such a transformation such as this, first commissions an environmental impact study, to know what values exist and to see if things can be done in such a way that cause the least loss of natural values.

A significant environmental impact

However, the Port Authority maintains that, as Maó is a State port, the environmental impact law does not apply, it has validity, they say, only in areas that have regional jurisdiction.

State regulation, however, is applicable over protected species. So, if works end up affecting a protected species, then there is a cumbersome terrain of reports, potential sanctions and specific authorisations. This is what has occurred at Cala Corb.

The dumping of rocks without control seriously affected a colony of protected coral that has been practically devastated. Had this been done by an individual, they would have been fined and in danger of being prosecuted through criminal channels.

Before a fait acompli, it was necessary to wait for a resolution from the corresponding ministerial department that had undertaken to contract a scientific service to move the remains of the coral to another part of the Maó port. Four years of paralysis and added costs for not wanting to realise that environmental laws are the same as others.

A new threat to the northern walkway: works and desalination plants

Recently, the Port Authority has put the management out to tender of the moorings by the northern walkway (the area known as s’Altra Banda) as well as those attached to the Isla del Rey.

Having consulted the specifications it can be deduced that whoever takes on the concession could significantly increase the number of moorings and, consequently, the areas where new installations could be put. To the 390 moorings that there are now, could be added another 250.

This intention contradicts two important points. In the first place, it implies adding a large number of new boats when Menorca has a study of the nautical load capacity of the island that was already saturated more than 10 years ago.

The second point is that it means altering new areas where no studies of the natural values have been presented.

The tender specifications also allow for installing various small desalination plants to provide water for the boats. But, there is no explanation for what is planned for the salt water generated by the desalination plants and it is not necessary to be very perceptive in deducing that it will be poured into the port itself which will significantly alter the natural environment.

The Port of Maó is a natural port

The large marine area that provides safe anchorage for Maó is a natural port that houses protected species and that offers important biological functions. The dynamic that tries to continue growth each year with new infrastructures and, furthermore, without doing previous studies on any environmental impact, serves to provide the basis for new environmental conflicts.

GOB has asked that any new pontoons are constructed with a system of “piles and fingers” (rather than with concrete blocks and chains) in order to better protect the seabed. They also requested that priority on waiting lists for a mooring be given to boats of traditional construction, with sail or electric drive motor.

It was also requested that no increases be made for moorings near areas where there is seafood, since water in a good condition is required and it is important to maintain economic diversification within the port.

Acting with a vision for the future

The proposal from GOB is that the orientation of the Port of Maó is focussed on improving the quality of its nautical services as well as improving shipyard boat maintenance and not on increasing the number of boats in the sea.

The level of the nautical saturation now seen in many of the coves during the summer, as well as the need to recover environmental values that have been lost due to excesses committed in the last decades, leads us to ask for a new commitment that is not based on quantity but on quality.

Positive Tourism (8) – Posidonia on the beaches

Views: 226

This is the latest announcement as part of the campaign for Positive Tourism that we have been publishing in the last few weeks on some parts of tourism that need to be managed in a different way.

On this occasion, the chosen theme is the presence of posidonia on beaches. It is of great value but even so is removed from the parts of the coastline with the most tourists.

This peculiar plant, that is colonising the sea, that makes flowers and can live thousands of years, is intrinsically linked with the formation of the beaches on our islands. Scientific studies estimate that most of the sand is made from organisms that reproduce in the posidonia meadows.

The debris that reaches the seashore helps to capture the sand moved with the wind to form dune systems. They are also important for curbing the effects of winter storms.

Posidonia captures large quantities of CO2, holding the carbon in its stems and releasing oxygen. It constitutes one of the richest ecosystems at animal level in our marine environment.

Scientific publications suggest that posidonia could be the longest living species of the biosphere. Samples taken from the waters of Formentera show them to be more than 100,000 years old.

However, it grows very slowly, so that it is vulnerable to human aggressive activity. In our environment, the indiscriminate anchoring of many boats, the discharge of poorly purified emissions, brine returned to the sea from desalination plants, and the disturbance of mud that clouds the waters caused by aggressive use of motorboat engines, are some of the causes of degradation that are being observed.

In the last few years, legal protection has progressed for this species that forms a habitat considered a priority at a European level. It is no longer removed from most of the natural beaches and now there are surveillance boats to stop anchoring over the posidonia meadows.

Yet, how surprising that the tourist industry still calls for its removal from urbanized beaches. With the knowledge we have of the outstanding contribution made by this marine plant, its presence should be valued. Posidonia is not dirt.

What is dirt is the massive presence of plastics that are a consequence of a production system generating an enormous quantity of non-biodegradable rubbish, which is left uncontrolled in the environment. Going to the root of this global problem by stopping buying from providers that do not evolve into using biodegradable materials ought to be a universal commitment and a general request should be heard from tourist spokespersons given that they represent the most powerful economic activity in the archipelago.

An unfavourable report on the reduction of marine protection of the Isla del Aire

Views: 188

The Balearic Ministry for Environment and Land has requested the General Directorate of Fisheries and Marine Environment that they recover, with urgency, the original area of the Marine Reserve of the Illa de l’Aire.

GOB has obtained access to various documents that are evidence of the adverse reactions and discomfort of different bodies and administrations relating to the removal of the 22% protection imposed by the Balearic Ministry of Fisheries and Food.

At the beginning of this month, a scientific study was published in which it was clear the enormous potential for the recovery of the Marine Reserve of the Illa de l’Aire, and showed how some areas with the best signs of regeneration had been those that are now unprotected. This provoked the Island Governing Council to show its disapproval and ask that the law be rectified.

We now know that the Planning Service of the Natural Environment, a service over seeing the management of the LICs (Places of Special Interest) and ZEPAs (Areas of special conservation) of the Nature Network 2000, sent an UNFAVOURABLE report on the lack of protection, showing how the modification to the law affects 87 hectares of Habitats of General Interest. The report from this body, which depends on the Balearic Ministry for Environment and Land, ends up by proposing that the said decree is rectified urgently so that the zoning of the reserve is recovered to its original state.

GOB reminds us that the objectives set by the European Union and the United Nations are aimed at ensuring that by 2030 10% of the marine surface will be strictly protected and, on this subject, Menorca fails with only 0.31% or 0.35% after the protection was reduced in the Special Diving Area of the Illa de l’Aire.

For these reasons, it is requested, publicly, that the Ministry of Fisheries and Food of the Balearic Government amends the decree and returns to protect the area of the Illa de l’Aire that it unprotected some months ago without the support of any technical report.

Pupils from two schools will continue analysing the sand in Son Bou and Algaiarens

For the third year running, two schools will analyse the sand from two beaches in Menorca to determine the presence of micro and mesoplastics.

Thanks to the support of the Sa Nostra Caixa de Balears Foundation and Bankia, through their call for Environmental and Sustainable Development, with the three sections of GOB in Menorca, Mallorca and Ibiza, continuity has been given to the citizen science project that started in Menorca in 2021.

Microplastic Watchers is a citizens science marine project integrated with the Observadores del Mar platform, that collects data on the presence and quantity of micro and mesoplastics in the sand of the beach, in order to work on the diagnosis and make aware of this global problem. Taking advantage of the location, a series of activities are carried out focussed on showing the participants the natural values of the coastal ecosystems and the problems that are found with them.

This year, the Primary School, Margalida Florit, in Ciutadella will be in charge of analysing the sand at Algaiarens in la Vall, and the Primary School Verge del Carme of Maó will work on the beach of Son Bou, to the south of the Island.

From the start of the project in January 2021, samples of sand have been collected and analysed each month as we published in July 2022.

Looking at the collected data, interesting information can be drawn. For example, on the Son Bou beach, on the conservative side, the data indicates that there could be more than a million and a half plastics (micro and mesoplastics) and that on the Algaiarens beach we found an average of 171 fragments per square metre.

Therefore, the samples analysed on this course will help to give accurate information on the degree of contamination from plastics that our beaches suffer. At the same time, we hope the activity will help the pupils as well as their families to understand more about the coastal ecosystems and raise awareness on the huge problem of plastic waste in the marine environment.

First walk “in-SOS-tenible” (unsustainable) against nautical overcrowding

Views: 227

In Menorca there is a project to double the sea area for doubling the Addaia sport Marina. There is also a plan to build dry marinas, for boats, in Cala Molí, Cala en Busquets, and Ciutadella. It is also planned to fill up the Cala Figuera area in Maó with boats. Continue reading First walk “in-SOS-tenible” (unsustainable) against nautical overcrowding
