RBINS and Zwin Nature Park install GPS transmitters on white storks

In the Zwin Nature Park in Knokke-Heist three young storks were provided with a transmitter at the end of June. Thanks to their transmitters, the movements of these storks can be followed at all times. With this study, the Royal Belgian Institute for Natural Sciences and the Zwin Nature Park want to document the consequences of changing conditions in the wintering areas on the migration behaviour of the storks.

Since Leon Lippens started an introduction programme for white storks Ciconia ciconia in the Zwin Nature Park in 1957, about five hundred young have hatched here (the first in 1965). More than 300 of them were equipped with a scientific ring, within the framework of the long-term research tradition and cooperation with the Royal Belgian Institute of Natural Sciences. The majority were reported at least once (on average five times per reported stork), mainly along an axis towards the southwest, through the western half of France and central Spain. The furthest observation of a Zwin-ooievaar came from Algeria, at 2,164 kilometres from the Zwin. But Belgian storks have also been reported to spend the winter in West Africa, south to Senegal and Mali. The white stork is one of the species for which the Zwin has been designated as a special protection area under the EU Birds Directive.

This year the Zwin population counted 13 breeding pairs. In the wider area, however, 27 additional pairs were documented (region Knokke-Heist, Damme, Bruges, and across the Dutch border), so that the total regional population in 2019 was no less than 40 breeding pairs. A few years ago, the feeding of storks in the Zwin was stopped, which probably contributed to their distribution over a larger area.

Transmitters in addition to rings

In 2019, the Zwin also devoted attention to the ringing of a number of young storks: on 5 June, 13 individuals were provided with a scientific ring. The codes on these rings can be read remotely with a pair of binoculars or a telescope, but the chance that a ringed stork is observed and reported remains rather small. Although such observations teach us a lot, they are still snapshots. With a transmitter, a bird can be tracked continuously, which provides much more information about the survival, the movements and the habitat use of the transmitter-equipped birds.

On 26 June, for the first time, three young Zwin storks (from two nests) were equipped with a transmitter. They weigh only 25 grams, which represents less than one percent of the weight of the birds. The transmitters are very sustainable: they operate on solar energy and transmit the data that their GPS collects via the GSM network. Don’t worry if there is no reception: everything is stored in the internal memory and passed on when a signal is available. It is also possible to adjust the transmitter parameters (such as the frequency of location measurements) remotely. The accuracy is astonishing, positions are determined to within a few meters.

Storks on garbage dumps

Before 1990, almost all Western European storks crossed the Strait of Gibraltar (the strait that separates Spain from Morocco) in the autumn to spend the winter in West Africa. Since then, however, much has changed. More and more storks have understood that they could drastically shorten this long and energy-consuming journey by staying in Spain, where they find all the food they need on landfills. In the winter of 2018-2019, up to 46,000 wintering storks were counted on the Iberian Peninsula. This is no less than 20% of the Western European population. These birds also have a higher chance of survival, and return more quickly to the breeding grounds in the spring, where they can occupy the best territories.

But … clouds are rising in the Spanish stork paradise skies! The European Waste Framework Directive prohibits landfills exposed to the open air, and the European Commission took Spain to the European Court of Justice in June 2018, in response to repeated calls for this legislation to be applied in Spain. The Spanish garbage dumps that many storks have learned to use will therefore be closed shortly. This will fundamentally change the state and conditions of their wintering quarters. The RBINS and the Zwin Nature Park are therefore seeking to use the transmitters to help document the impact of this changing situation in Spain on the storks’ migratory behaviour.

The results of the research will be available on a specific project page on the website of the Zwin Natuur Park. It is the intention that more storks will be equipped with a transmitter in the coming years.

As an international airport for birds, the Zwin Nature Park is a knowledge and expertise centre for bird migration. In addition to ringing storks and installing transmitters, the Zwin Nature Park also focuses on ringing of other bird species. From 1 August to 20 October 2019, ringing will take place almost every day, and the public will also be able to gain an insight into this activity. In Belgium, the scientific ringing of birds is coordinated by the BeBIRDS group of the Royal Belgian Institute of Natural Sciences (RBINS).

EuroGOOS, the European Global Ocean Observing System

EuroGOOS is the European component of the Global Ocean Observing System of the Intergovernmental Oceanographic Commission of UNESCO (IOC GOOS). The EuroGOOS Secretariat is located in Brussels, serving 44 members and supporting five regional systems in Europe. The Royal Belgian Institute of Natural Sciences (RBINS), and in particular its Marine Forecasting Centre, is one of these members and is involved in the North West Shelf Operational Oceanographic System (NOOS).

EuroGOOS identifies priorities, enhances cooperation and promotes the benefits of operational oceanography to ensure sustained observations are made in Europe’s seas underpinning a suite of fit-for-purpose products and services for marine and maritime end-users.

EuroGOOS working groups, networks of observing platforms (task teams), and regional systems (ROOS), provide for a for cooperation, unlock quality marine data and deliver common strategies, priorities and standards. The many EuroGOOS networks work towards integrated, sustainable and fit-for-purpose European ocean observing, underpinning the EOOS (European Ocean Observation System) framework.

EuroGOOS General Assembly – New Relevance, New Strategy

On 8 and 9 May the EuroGOOS General Assembly met in Heraklion, hosted by the Hellenic Centre for Marine Research and George Petihakis, EuroGOOS Chair. EuroGOOS strategy and integration were the main themes on the agenda. The meeting was attended by EuroGOOS members and the chairs of the EuroGOOS activities (working groups, infrastructure task teams, and the regional systems – ROOS).

The Assembly discussed the evolution of the organization and brainstormed on the next EuroGOOS strategy 2020-2030. The brainstorming was done through an interactive session in a World Café around four major areas of the strategy: high-level priorities, challenges, partnerships, and national benefits and advocacy. The results of this brainstorming will be transformed into the strategy and an accompanying roadmap, with the first draft prepared in the summer. The upcoming OceanObs’19 conference will further feed into the strategy preparation.

The Assembly also discussed ways to achieve a better integration between the variety of EuroGOOS activities. EuroGOOS task teams (networks of ocean observing technologies) and working groups (on science, technology, data integration and coastal ocean) are delivering best practices and state of play analysis, while the EuroGOOS Regional Operational Oceanographic Systems (ROOS) deliver regional coordination. At the end of 2019, EuroGOOS will host an integration workshop bringing all those activities together, to brainstorm and agree on steps to activate the new EuroGOOS strategy, and on the support needed from the EuroGOOS office.

New members, new hosts

At the formal part of the meeting, the Assembly approved and warmly welcomed three new members to EuroGOOS: SHOM (France), PLOCAN (Spain) and NIVA (Norway). Representatives of these organizations showcased their activities and future contributions to EuroGOOS, spanning technological development, observing integration, ocean monitoring, and ocean literacy. The Assembly also elected a new member to the Executive Directors Board – Holger Brix of the Helmholtz-Zentrum Geesthacht in Germany. Two Executive Board members stepped down upon the completion of their full mandates – the Assembly thanked Urmas Lips (Tallinn University of Technology, Estonia) and Bernd Brugge (Federal Maritime and Hydrographic Agency, BSH, Germany)  for their contributions to the work of the Board over the past six years. At the Assembly, Chair George Petihakis also signed the EuroGOOS office hosting agreement with the Royal Belgian Institute of Natural Sciences (RBINS), represented by Patrick Roose and Sebastien Legrand. RBINS will host the EuroGOOS secretariat in its Brussels offices (also housing the Belgian Museum of Natural Sciences) from the end of 2019.

When originality makes you sail- a fourth grade class on the Belgica

The naming of Belgica II, the new Belgian research vessel that will succeed the Belgica at the end of 2020, was announced on 25 April 2019 and caused a great deal of ink to flow. However, if originality and cinematographic creativity had been the most important selection criteria, the new vessel would have been called “Gamma Ruspo”. This name was suggested by the students of class 4B of the Institut de la Providence de Champion, Namur. A reward was also announced for the most original video, so the students were expected on Monday 20 May in the military port of Zeebrugge, to sail on the Belgica for half a day. Captain Haddock’s shadow will be hanging over the North Sea…

On November 6th, 2018, the Belgian Federal Science Policy Office launched a contest in order to determine the name of the new Belgian oceanographic vessel. After a first phase in which schools could suggest names (accompanied with an explanatory video) and a second phase where everyone could choose one of the six selected names, the Minister for Science Policy announced the chosen name on 25 April 2019: “Belgica II”. The winning class, 1LA from Liège’s Athénée Maurice Destenay could enjoy a cruise on the Belgica the same day.

Nonetheless, a second laureate was chosen to reward the most convincing video, emphasising originality. For this prize, a jury determined that the class 4B of the Institut de la Providence de Champion (Namur) had realised the most original production. Their video was inspired by the comic heroes Tintin and professor Calculus, and states why they would have called the new vessel “Gamma Ruspo”. On 20 May 2019, this class also benefited from an excursion with the RV Belgica.

Scientists explain the measuring equipment on a tripod that will be placed on the seabed.

The Institut de la Providence, a green school interested in marine sciences

On the initiative of its direction, professors and students, l’Institut de la Providence is a school which has been engaging in multiple initiatives in terms of environmental protection for a long time: installing photovoltaic panels, replacement of all lighting with LEDs, managing beehives with a didactic hive in the classroom, signing of the “Green deal sustainable canteens” contract, soft mobility week from 20 to 25 May 2019, investment in recyclable cups and water fountains, environmental certification process, etc.

It is thus no surprise that the students of class 4B of the Institut de la Providence de Champion have heard of the naming contest in their French class. Before suggesting a name for the successor of the Belgica, everyone was invited to investigate and learn more about this venerable vessel. Consequently, the teenagers learned that it collects important information which contributes to thinking about sustainable fisheries, offshore wind turbines, mining activity in the deep sea, or offshore energy production and storage. The pooling of information made it possible to launch lines of thought to formulate original names for the successor of the Belgica.

It was a particularly busy day in the laboratories of the Belgica.

Gamma ruspo

After a flamboyant debate, 4B went for originality. What if we called this vessel “Gamma Ruspo?”.

Gamma rus what? The “Gammarus pulex” is a type of shrimp, “ruspo” means “I search” in latin, and there is no need to explain the link between the word “Gamma” and the world of science.

The name being chosen, it was time to go through the second part of the competition: film a one and a half minute video presenting the suggested name in an original way. A small group of students turned into a film crew and at the end of January, without anybody’s help, they shot a video in which  typically Belgian characters (Calculus and Tintin) are associated with the playful and scientific universe of “C’est pas sorcier” (French educational television programme). The result was quite successful on the internet and aroused reactions as far as Austria (the video has been translated in the three national languages).

Interpretation of Tintin – one of the protagonists of the winning film – by one of the students.

The outcome

In February 2019, the decision was made: “Gamma Ruspo” was not selected as one of the names from which the public could choose. The students were rather surprised to hear that the new Belgica was named… “Belgica 2”! They didn’t think this contest would result in this choice, although it is a strong mark that honours Belgian marine research’s history and tradition.

However, the Providence students were fair players, admitting that the name they suggested perhaps lacked readability. Although they were a little disappointed, they were still satisfied to have participated in the competition with a nice group work and a cool video.

April 2019, big surprise: a message from one of the contest organiser informed them that their video has won the award for being the most creative submission.

Dominique Rappe, the 4B’s French teacher, reacts: “It’s great that the class is rewarded, because many have gone really far in their thinking, proving their interest in biology, climate, and sciences in general. The film crew has been completely autonomous, and it is their intuitive talent that has been rewarded. Everyone is delighted that they were able to go on an excursion with the Belgica on Monday 20 May. We prepared the visit so that the youngsters could gather a maximum of information from the scientists that were carrying out research on that day. They also questioned the military staff that operates the vessel. The class even offered a little animation (song) in recognition of the adults that welcomed them in their professional environment.”

The students are amazed at how much can be told about a bottle of seawater.

Inventories of macro-and micro-plastics in the Belgian fishing areas and on the beaches

The research partners of the EMFF-FIVA-research project MarinePlastics have started a study that accurately maps how much and what types of plastic are found on the Belgian fishing grounds. It involves both larger pieces of waste (macro-plastics larger than 5 mm) and minuscule plastic particles (micro-plastics smaller than 5 mm).

Since 2012, Europe has been asking each Member State to collect figures about macro-plastics on the seabed. From this year onwards, data must also be collected on micro-plastics in the sediment and in the water. The waste on the beaches must also be monitored.

The project MarinePlastics also examines the extent to which microplastics are found in the commercial fish from our fishing areas. The researchers make the distinction between the plastic particles in the fish stomach (which people do not consume) and the fish fillet (which we do eat).

Macro-plastics in the Sea and on the Coast

For almost 10 years, the Research Institute for Agriculture, Fisheries and Food (ILVO) has been voluntarily collecting data on plastic, which is hoisted on board the research vessels within existing measuring campaigns aimed at the state of fish stocks and the impact of human activities at sea. The plastic contained in the fishing nets was sorted, described, measured and weighed according to the standards of OSPAR and the European Marine Strategy Framework Directive (MSFD). It is those data that are now undergoing a statistical depth analysis.

Bavo De Witte: “From a first rough interpretation it is already apparent that the amount of macro-plastic found is increasing and that there are hotspot sites, such as the dredge disposal location Zeebrugge Oost, where port sludge is dropped and currents create a sedimentation effect.” The analysis should clearly show quantitative and qualitative trends. Comparison with numbers from abroad also become possible.

ILVO and the Operational Directorate Natural Environments of the Royal Belgian Institute of Natural Sciences (RBINS-OD Nature) also want to investigate whether the waste can be linked to human activities such as tourism, industry or fishing. In addition, each type of waste will study whether the quantities are increasing or decreasing.

RBINS-OD Nature also concentrates on what is found on the Belgian beaches. The quantity of beached waste is not decreasing, they notice from prior analyses. On the beaches too, the situation is poor, according to the evaluation for the European Marine Strategy Framework Directive.

Micro-plastics in Sediment, Water and Commercial Fish

Micro-plastics can come directly into the environment by wear and tear of tyres, through clothing or through soaps and scrubs. A previous study showed that up to 50% of these ‘land-based’ microplastics eventually end up in the sea.

Micro-plastics accumulate in the water and on the seabed and fragment even further into nanoparticles (less than 1 micrometers). Sooner or later these micro-and nano-plastics are absorbed by fish, mussels, shrimps and other animals, which eventually end up in the human food chain. Some of those small plastic particles will undoubtedly stay behind in the parts that we do not eat, like the stomach of a fish. A detailed characterization of micro-plastics in certain marine and fishery products would make clear how many micro-plastics we are really eating now. This is important to assess the potential health risks of micro-plastics.

“In the case of a scientific risk analysis, two factors must always be examined”, researcher Bavo De Witte clarifies. “First: To what extent are you exposed to the substance – in this case micro-plastics? And secondly: is there a toxic effect that can be associated with that degree of exposure? None of these two questions is currently adequately answered by science. So before we can make statements about the degree of (non-)harmfulness, we are now first and foremost mapping how many microplastics a person is actually ingesting.”

Within this project, RBINS-OD nature and ILVO are also joining forces to study the presence of micro-plastics in the marine environment. European legislation expects each Member State to follow the quantity of micro-plastics in the seabed and seawater.

MarinePlastics is an initiative of Flanders Research Institute for Agriculture, Fisheries and Food (ILVO) and the Royal Belgian Institute of Natural Sciences (RBINS – OD nature).

EMFF-FIVA stands for the European Fund for Maritime Affairs and Fisheries and the financial Instrument for Flemish fisheries. It is a research funding agency for fisheries-related subjects using European and Flemish funds.

Documenting underwater sound in the Belgian North Sea

Sound is everywhere. Not only on land but also in the seas and oceans. Some sounds are of natural origin, but human activities add to the marine soundscape as well. We don’t have a good understanding of the types and distribution of these underwater sounds yet, let alone of the effects that they may have on marine fauna. At the end of May 2019, a permanent acoustic recording station was installed in the Belgian part of the North Sea. This major accomplishment is framed in the project Joint Monitoring Programme for Ambient Noise North Sea’ (JOMOPANS). The new equipment will help scientists to understand how underwater noise is distributed over the North Sea.

If you picture the underwater environment to be a silent and serene world, you may have to reconsider. Sounds are omnipresent, also in the marine environment. Underwater sound can be produced by natural (waves, weather, animals) and anthropogenic (shipping, construction) sources. However, our understanding of the effects of these sounds on marine fauna is still limited. In recent years, the introduction of underwater sound in the marine environment started to receive political and scientific attention, and monitoring schemes are being set up.

Impulsive sound

Most of the monitoring effort however, is attributed to impulsive sound. This category of noise consists of sounds with a short duration (impulse-like), that are largely unwanted and of anthropogenic origin. Pile-driving for the construction of offshore wind turbines, sonars and the destruction of ammunition at sea are the best known sources of impulsive sound. These can potentially be harmful for marine fauna. A temporary relocation of Harbour porpoises Phocoena phocoena was already shown during pile-driving activities, and scientists have also gained some insight into the effects of impulsive sounds on fish. But to understand the full impact on these and other marine organisms, a lot more study is still needed. The growing knowledge is being translated into regulations. Belgian legislation for instance already prescribes that the level of anthropogenic impulsive sounds is not allowed to be higher than the level at which harmful effects can be shown. For pile-driving, the threshold is currently defined at 185 dB at 750 m of the sound source. Sound mitigation measures should be put in place when this limit is exceeded.

Continuous sound

Our understanding of the levels and spatial and temporal patterns of continuous, ambient sounds in the marine environment on the other hand, is currently much less developed. These sounds – typically of low frequencies – may show an increasing trend due to the increase in human activities such as shipping, dredging, sand extraction, fishing and sustainable energy production at sea. Potential negative effects on marine fauna can be subtle and chronic and are therefore harder to evaluate. The limited amount of available data does not yet allow reporting to national and international policy makers.

Continuous monitoring of ambient sound

As sound sources, sound transmission, and the distribution of vulnerable species are all transnational questions, these also should be tackled transnationally. The international reporting obligations of EU Member States for the Marine Strategy Framework Directive (MSFD) strongly pushes the development of a regional approach, both with respect to monitoring and methodology. Belgium effectively engaged to contribute to such an international approach and use the results for the national evaluation. To accomplish this, the Royal Belgian Institute of Natural Sciences (RBINS) joined the JOMOPANS project.

In this project, RBINS is (among other tasks) responsible for the installation of a permanent acoustic recording station in the Belgian part of the North Sea. The Westhinder platform was selected as a suitable location. Essentially serving as an automatic electronic light platform, the Westhinder now also plays an important role as node of the monitoring network of the Flemish Maritime and Coastal Services Agency. At the end of May 2019, the JOMOPANS sound recording station was added to this platform. Technicians from the Maritime and Coastal Services Agency and the RBINS scientific divers respectively took care of the aerial and underwater parts of the installation. The instrument will continuously monitor ambient underwater sound generated by both natural and anthropogenic sources. Check the illustrative video!

Towards knowledge-based management

“The recently installed acoustic recording system will deliver the high-quality data that are needed to describe the types (level and frequency) and timing of sounds around the Belgian measuring station.” Says Alain Norro, scientific diver of RBINS. “In combination with data yielded by other JOMOPANS stations, we will begin to understand how underwater noise is distributed over the North Sea.” As such, the Belgian station will be an essential part of the network that will deliver the tools necessary for scientists and managers to incorporate ambient noise in their assessment of the environmental status of the North Sea. In a next step, the effectiveness of various options for reducing the potential environmental impact of ambient underwater noise in the North Sea basin, will be evaluated.

JOMOPANS is an Interreg project (North Sea Region) funded by the European Union’s European Regional Development Fund. The project consortium consists of 11 partners from 7 countries (RBINS being the sole Belgian partner) and is coordinated by Rijkswaterstaat (Netherlands).

Summer Exhibition ‘Kijk, een Walvis (Look, a Whale)’ in De Haan

From 1 July to 31 August 2019, the summer exhibition ‘Kijk, een walvis (Look, a whale)’ will take place in the community centre ‘t Schelpestik in De Haan (Vosseslag 131, 8420 De Haan). The local stranding of the whale Antonius in October 2018 triggered the initiative, and several skeletal parts of this impressive animal have since returned to De Haan to form the backbone of the exhibition. The municipality of De Haan also spared no effort in addressing various experts and collections to bring together a unique collection of marine mammal bones and whale-related items. The exhibition can be visited daily between 10 a.m. and 1 p.m. and between 2 p.m. and 5 p.m. during this period, and admission is free. A tip for the summer months!

Antonius

On 24 October 2018, the carcass of a Fin whale Balaenoptera physalus was spotted in the Belgian part of the North Sea. Because it floated in a busy shipping lane, it was decided to bring it ashore in a controlled manner. On 25 October, around 2 a.m. at night, the carcass arrived on the beach of Vosseslag, De Haan. Within one day the animal was completely disposed of. Action had to be quick as a spring tide was approaching. “It was a fantastic experience to witness the perfect cooperation between many government agencies, at every level of government, and scientific institutions, resulting in a thorough scientific investigation and a quick and efficient removal of the remains,” says Jan Haelters, coordinator of the Belgian stranding network and marine biologist at the RBINS, with justified pride.

The autopsy, carried out by veterinarians and students of the universities of Ghent and Liège and biologists of the RBINS, showed that the almost mature male, 18 m long and weighing about 30,000 kg, had probably died a natural death. “I immediately saw the potential of this event and asked the city council for permission to have parts of the skeleton prepared.” Wilfied Vandaele, mayor of De Haan, announces. This permission was granted, and the Faculty of Veterinary Medicine of the University of Ghent prepared not only the mandibles but also a pectoral fin and a vertebra of the whale, which in the meantime had been baptised Antonius.

Marine Mammals in De Haan

Fin Whale Antonius obviously is the eye-catcher of the exhibition, but this was not the first unfortunate marine mammal that ended up on a beach in De Haan. “Parts of a number of rare specimens that washed ashore in this municipality in the past have also been prepared and are now part of the RBINS collection.” explains Olivier Pauwels, curator of the RBINS vertebrate collection. Mayor Vandaele adds: “We were given some skeletons and remains of marine mammals on loan, such as the skull of a young Killer whale Orcinus orca that beached in 1843. These items are used in the second part of the exhibition to illustrate the life and problems of marine mammals.”

Furthermore, two skulls of Sowerby’s beaked whales Mesoplodon bidens (mother with juvenile, washed ashore in 1933 in Harendijke in the district of Wenduine) and one of a Long-finned Pilot Whale Globicephala melas (washed ashore in 1995 in De Haan) found their way from Brussels to the summer exhibition. And because the district of Wenduine has a special relationship with the Harbour porpoise Phocoena phocoena (the species appears in Wenduine’s coat of arms), a porpoise skull has also been added to the collection lent out by the RBINS. “Thanks to Fin whale Antonius and the animals that beached in De Haan previously, and thanks to the cooperation with the municipality of De Haan, we have the opportunity to connect two major pillars of our institute – research and collection – and to put them in the spotlight together!” explains Kelle Moreau, marine biologist and spokesman for the RBINS.

Extra information and activities

Finally, the De Haan staff also visited the Dutch nature centre Ecomare on Texel. Some dolphin skeletons were borrowed here, as well as a series of historical utensils related to whaling. In the margin of the exhibition, also a number of other activities have been set up. For example, there are a cycling and hiking tour and creative workshops for children.

The unique combination of the story (and parts) of Antonius and various other biological and historical stories, told by means of rare artefacts, elaborated on clear information panels and extended with additional activities, render ‘Kijk, een walvis’ an exhibition that is definitely worth a visit! Highly recommended for young and old, and a valuable tip for the summer months!

Mummies in Africa

…or as close as you can get to Africa in Brussels. On Friday 14 June, the MUMM team of the Royal Belgian Institute of Natural Sciences (RBINS) visited the renovated AfricaMuseum in Tervuren as part of their annual team building.MUMM stands for ‘Management Unit of the Mathematical Model of the North Sea’ and brings together the RBINS scientists who advise the government in relation to human activities in the Belgian part of the North Sea (the MARIMA team), perform aerial surveillance (the SURV team, additionally the OO-MMM pilots were also invited) and also carry out the federal monitoring of marine mammals at sea, coordinate the stranding network, study eutrophication and report to Europe on the state of health of our part of the North Sea. The development and maintenance of scientific websites and applications of the Operational Directorate Natural Environment (OD Nature, the largest scientific directorate within RBINS) is also carried out by MUMM specialists (the SWAP team). A large and diverse team, which was redivided several times in different ways during the team building day to bring employees with different tasks/mother tongues together!For their visit to the AfricaMuseum, the mummies opted for the guided tour ‘A blend of Central Africa’, in which they were provided information on the material culture, immaterial heritage and biodiversity of Central Africa for two hours. Of course, Belgian colonial history could not be overlooked either, and how we can deal with it in the current context. Contemporary themes such as the multicultural society and sustainable development completed the story. Some also ventured into a few African dance steps.After an interesting visit to the museum and a walk in perfect weather conditions, we made our appearance for lunch in the Tervurian restaurant ‘De Linde’, where we enjoyed the June edition of the market menu. The succession of very tasty appetizers, starters, main courses and desserts, accompanied by aperitifs and adapted wines (optional, of course), made us leave the restaurant satisfied.Producing a group photo was just about the only thing we were able to do afterwards. Out of sheer necessity, we then went to a nearby terrace to recover from the feast.

Marine mammals in Belgium in 2018

Scientists from the Royal Belgian Institute of Natural Sciences (RBINS) summarised the available information on marine mammals in Belgium in 2018 in the new edition of the dedicated report series. The latest edition includes an overview of the strandings and sightings of marine mammals, remarkable fish and a leatherback turtle in 2018, as well as opinion pieces about the sense and nonsense of taking seals into care, the impact of waste on marine mammals and the use of the port of Nieuwpoort as a resting place for seals.

As every year, RBINS has collected data on marine mammals in Belgium. For 2018, this happened with the cooperation of SEALIFE Blankenberge, the University of Liège and Natuurpunt. In 2018, 134 marine mammals washed ashore dead or dying in Belgium, concerning 89 harbour porpoises, 1 white-beaked dolphin, 1 fin whale, 18 grey seals, 11 harbour seals and 14 seals that were not identified to species. In addition, SEALIFE Blankenberge took 30 seals into care: 17 grey and 13 harbour seals (the highest number of grey seals ever, and for the first time more grey than common seals).

Ten percent of the harbour porpoises for which the cause of death could be established had died from drowning in fishing nets, and 30% from predation by grey seals. The fin whale, an 18-metre-long male found dead at sea, presumably died from a natural cause. The number of stranded dead and dying seals (43) was the highest number ever. Six of the grey and one of the harbour seals were believed to have died from incidental capture. One grey seal died entangled in a piece of nylon rope, and another choked on a flatfish.

The most striking sightings in 2018 concerned very high numbers of harbour porpoises in April (estimated at almost 20,000 in the Belgian waters, based on aerial counts) and the relatively frequent occurrence of bottlenose dolphins.

The annual report also contains editorials about the sense and nonsense of taking seals into care, the impact of waste on marine mammals and the use of the port of Nieuwpoort as a resting place for seals.

More than 40 signatories to the Brussels Declaration on the oceans and climate change

On February 19, the international conference “Climate change and ocean conservation” took place on the initiative of the Belgian ministers of Energy, Environment and Sustainable Development and of the North Sea. The Declaration was very well received at the conference, and continues to receive support. 33 countries and 11 organisations have already signed the Declaration.

The Brussels Declaration calls for progress in several ongoing processes, in particular those regarding the negotiation of a new Convention on high seas biodiversity and the definition of new objectives for the Convention on Biological Diversity.

The Declaration also has the great merit of bringing together the many existing commitments on oceans and climate in a single document that countries can sign up to, and calls for an appropriate reaction to the UN Climate Commission’s Oceans Report, which will be published in September 2019.

The Declaration was signed by countries and by organisations

Many countries support the Declaration: European countries but also countries from Africa, Latin America, Asia, and many islands. Chile, where the next Climate COP (COP 25 or “the Blue COP” as the Chilean Minister for the Environment calls it) will take place in December 2019, has committed itself to promoting the objectives of the Declaration during this conference. The following countries, among others, have signed the Declaration: Belgium, Denmark, Finland, France, Luxembourg, the Netherlands, Portugal, the United Kingdom, Sweden, Albania, Bosnia-Herzegovina, Norway, Iceland, Monaco, Gabon, Ivory Coast, Morocco, Cape Verde, Chile, Costa Rica, Honduras, Nicaragua, Peru, Tajikistan, Dominican Republic, Commonwealth of Dominica, Marshall Islands, Sao Tome and Principe, Seychelles, Saint Lucia, Saint Kitts and Nevis, Saint Vincent and the Grenadines…

Several international organisations have also signed the text, such as: EIB (European Investment Bank), Future Ocean Alliance (an independent organisation financed by the Global Environment Facility – the world’s largest donor for environmental improvement projects), Wind Europe, Ocean Energy Europe, Ocean Care, Air Centre, Natural Resources Defense Council (NRDC), Global Ocean Trust, RBSA (Royal Belgian Shipowners’ Association), VLIZ (Flemish Institute of the Sea), RBINS (Royal Belgian Institute for Natural Sciences).

During an event organised by the Permanent Representation of Belgium to the United Nations in New York in early April, the Belgian ambassador invited countries to join this growing group. The new signatories were invited by Ministers Marghem and De Backer to a second signing ceremony on May 7 at the FPS Public Health.

“Unfortunately, the state of biodiversity has become extremely alarming. With the Brussels Declaration, the federal government wants to commit itself, together with the ministers, ambassadors and representatives of 33 countries and several organisations, to tackling the impact of climate change on the oceans. I call on other countries to join us in order to strengthen our action at European and international level”, declared Marie Christine Marghem.

And in practice?

Belgium is already working hard to put the Declaration into practice. Recently, Belgian and European climate and ocean negotiators met to see how they can include the oceans in the concrete objectives of the next climate COP. Belgium, together with other countries, is also one of the driving forces of the “Friends of the Blue COP” group. 2019 will be a decisive year, as the ‘blue’ COP at the end of the year is a unique opportunity to take climate measures to protect the oceans.

More concretely, Minister De Backer announced on May 7 that Belgium officially supports the 30×30 initiative, a call for action to protect 30% of the oceans by 2030. Belgium has already protected more than 35% of the Belgian part of the North Sea, but to really protect the oceans against climate change, we need to establish a vast network of marine protected areas. Belgium will promote this objective in all policy processes on climate, oceans and biodiversity.

“Only through international cooperation will we be able to halt climate change and its adverse effects on our seas and oceans. Everyone must make an effort. That is why I am signing the international commitment to protect 30 percent of our oceans by 2030. However, Belgium is even more ambitious than that, and already protects 35 percent of its part of the North Sea. Together we can keep our seas and oceans clean”, concluded Minister Philippe De Backer.

The United Nations Environment Programme Calls for Better Governance of Global Sand Resources.

The United Nations Environment Programme (UNEP) launched a new report in Geneva on 7 May 2019 examining the views of various stakeholders on the sustainability challenges of sand extraction and use. With this report, UNEP aims to stimulate a global debate on sand extraction, following the recent adoption of a new resolution on better governance of mineral resources by the 4th UN Environment Assembly.

Sustainability Challenges of the Global Extraction and Use of Sand Resources

The scale of sand and gravel extraction worldwide makes it one of the major sustainability challenges of the 21st century. An estimated 40 to 50 billion tonnes of sand is extracted annually from quarries and wells, in rivers, along coasts and in the marine environment. The growing world population, urbanisation, shifts in our consumption patterns, and the associated development of infrastructure, are important factors that have tripled the extraction of easily available sand resources over the past two decades. Without sand, there is no concrete, no asphalt, no glass, … and therefore no schools, hospitals, roads, solar panels or other necessary infrastructure. Water purification and land reclamation are also major users. Sand is even used in the industrial production of electronics and cosmetics … After water, it is nowadays the most reclaimed natural resource. Furthermore, dams and extraction have reduced the sediment supply from rivers to many coastal areas, leading to reduced deposits in river deltas and accelerated beach erosion.

The growing trend of unsustainable and illegal sand extraction in marine, coastal and freshwater ecosystems has far-reaching environmental, social and economic consequences (e.g. tourism, fisheries). However, scientific research and monitoring, as well as adequate policies to support responsible extraction and consumption, are lagging behind in many parts of the world. In the meantime, international trade in sand and gravel continues to grow. Due to the high demand in regions without local sand and gravel stocks, this business activity is expected to increase by 5.5% per year. As a result of international sand extraction bans, sand extraction for land reclamation projects, and the effects of unregulated sand extraction in international rivers, sand and gravel extraction has also become a rapidly growing transboundary issue.

There is no global monitoring of sand use. Cement however is well reported. Monitoring of these data reveals that cement production has tripled over the past two decades. (© UNEP/GRID-Geneva)

 

New Solutions for Better Governance of Global Sand Reserves

The United Nations Environment Programme recognizes the need to reconcile global policies and standards with local sand availability, development needs and enforcement realities, and is committed to highlighting these challenges in order to improve governance, together with all stakeholders. The organisation therefore looks forward to the further development of effective tools that will enable better monitoring of the extraction and use of sand resources and efficient decision making in relation to the mitigation of the consequences of sand extraction.

The new report ‘Sand and Sustainability: Finding New Solutions for Environmental Governance of Global Sand Resources’ is based on this theme. It draws attention to the sustainability challenges and solutions for sand extraction and consumption, and recommends joint actions to update existing standards, set up monitoring programmes and initiate a dialogue throughout the value chain. In addition, it calls for the avoidance of unnecessary sand consumption, the use of more recycled and alternative materials, and the reduction of environmental impacts through more responsible mining practices. The report was produced in October 2018 during an expert dialogue facilitated by UNEP/GRID-Geneva (GRID = Global Resource Information Database) and the University of Geneva with funding from the Swiss Federal Ministry of Environment.

UN Resolution on Better Governance of Mineral Resources

The ‘Sand and Sustainability’ report follows the recent adoption (April 2019) of a new resolution on better governance of mineral resources by the 4th UN Environment Assembly, and was officially presented on 7 May 2019 at the Palais des Nations, Geneva, in the presence of Ms Joyce Msuya, UNEP’s acting director. The resolution focuses on gathering information on sustainable practices and knowledge gaps, and on listing implementation strategies and assessment methods. The report is to be submitted to the fifth session of the United Nations Environment Assembly.

Marine Sand Extraction in Belgium

In the meantime, Belgium is continuing to invest in better management of its mineral resources. For more than 40 years, sand has been extracted in Belgian marine waters under the authority and control of the FPS Economy, S.M.E.s, Self-employed and Energy. “In order to support long-term management, a geological knowledge base has been developed for the Belgian and southern Dutch parts of the North Sea, which makes the available quantities per sand quality available for consultation.” explains Vera Van Lancker of the research group ‘Suspended Matter and Seabed Monitoring and Modelling’ of the Royal Belgian Institute of Natural Sciences. “In addition, a link with a numerical toolkit makes it possible to calculate different impact scenarios of extraction.” The final report of the project TILES or ‘Transnational and Integrated Long-term Marine Exploitation Strategies’ is available on the website of the Belgian Federal Science Policy Office (BELSPO). As the stocks are not inexhaustible, there is a call for more thoughtful exploitation strategies.
