Description
Description (EN): Project aims to develop a sustainable, cost-effective framework for plastic litter detection, monitoring and management in marine and coastal environments. Plastic litter is linked with negative economic, social and ecological consequences and common challenges related to plastic litter are complex: increasing amounts of microplastic, direct harm to the marine biodiversity and negative impacts on recreational activities. Absence of physical coastal borders between Latvia and Lithuania means that actions taken in one country might affect the other. Plastic that accumulates in algal wracks on the shore or in algal scum might be a target area for plastic pollution estimation and mitigation measures. The project aims to link remotely sensed features (Earth observation from space and drones) with marine plastic litter in such areas and suggest a joint and efficient approach for monitoring and management, which can be used by municipalities or national authorities in Lithuania and Latvia. Moreover, in relation with a single-use plastic ban from the year 2021 project aims to screen alternatives to replace single-use plastic, assess environmental, social and economical impact of marine litter pollution and it’s reduction; engage consumers, retailers, local municipalities, industry representatives, residents, environmental groups and tourism associations – to ensure broad support of a ban of single plastic use in coastal areas.

Tarša plastiko šiukšlėmis yra susijusi su neigiamomis ekonominėmis, socialinėmis ir ekologinėmis pasekmėmis ir susiję iššūkiai yra kompleksiški: didėjantys mikroplastiko kiekiai, tiesioginė žala jūrų biologinei įvairovei ir neigiamas poveikis rekreacinei veiklai. Fizinių sienų tarp šalių nebuvimas lemia, kad vienoje šalyje taikomos priemonės gali turėti poveikį kitoje šalyje. Plastiko šiukšlės mikrodumblių santalkose vandens paviršiuje ar makrodumblių sankaupose pakrantėje gali būti vietos, kuriose būtų vertinama tarša šiukšlėmis ir taikomos mažinimo priemonės. Projektu siekiama susieti nuotolinius tyrimus (Žemės stebėjimas ir bepilotės skraidyklės) su jūrą teršiančio plastiko vertinimu tokiose vietose ir pasiūlyti bendrą stebėsenos ir taršos tvarkymo metodą, kurį galėtų naudoti savivaldybės ar nacionalinės institucijos Lietuvoje ir Latvijoje. Be to, atsižvelgiant į nuo 2021 metų ES numatytą vienkartinio naudojimo plastiko gaminių draudimą, projektas siekia įvertinti alternatyvas, skirtas pakeisti vienkartinio naudojimo plastikinius gaminius, įvertinti kaip tai prisidės prie jūrą teršiančių šiukšlių kiekio mažinimo, bei koks bus kompleksinis poveikis gamtinei aplinkai, socialinei ir ekonominei (ESE) gerovei, įtraukti pagrindines suinteresuotųjų šalių grupes, vartotojus, verslą, vietos savivaldybes, pramonės atstovus, pilietinę visuomenę, aplinkosaugos grupes, turizmo asociacijas, tam, kad būtų užtikrintas platus vienkartinio plastiko naudojimo mažinimas pakrančių teritorijose.

Piesārņojums ar plastmasas cietajiem atkritumiem ir saistīts ar negatīvām ekonomiskām, sociālām un ekoloģiskām sekām un kopīgās problēmas, kas saistītas ar piesārņojumu ar cietajiem atkritumiem, ir kompleksas: pieaugošais mikroplastmasas daudzums nodara kaitējumu jūras bioloģiskai daudzveidībai un negatīvi ietekmē atpūtas aktivitātes. Fizisku piekrastes robežu neesamība starp Latviju un Lietuvu nozīmē, ka vienā valstī veiktās aktivitātes var ietekmēt otru. Plastmasa, kas akumulējas aļģu sanesumos piekrastē vai jūrā, varētu būt mērķa zonas plastmasas piesārņojuma novērtēšanai un samazināšanai. Projekta mērķis ir sasaistīt attālinātos mērījumus (Zemes attālinātu novērošanu no kosmosa un droniem) ar piesārņojumu ar cietajiem plastmasas atkritumiem aļģu sanesumu zonās un ierosināt kopēju un efektīvu uzraudzības un pārvaldības pieeju, kuru varētu izmantot Latvijas un Lietuvas pašvaldību un valsts iestādes. Turklāt saistībā ar vienreiz lietojamo plastmasas aizliegumu sākot ar 2021. gadu, projekta mērķis ir izskatīt vienreiz lietojamo trauku alternatīvas, novērtēt vide, piesārņojuma ar cietajiem atkritumiem un tā samazināšanas radītās ietekmi uz vidi, sociālo un ekonomisko situāciju; iesaistīt patērētājus, mazumtirgotājus, vietējās pašvaldības, nozares pārstāvjus, iedzīvotājus, vides aktīvistu grupas un tūrisma asociācijas, lai piekrastes zonās nodrošinātu plašu atbalstu vienreizējās plastmasas lietošanas aizliegumam

The quantities of litter found on Lithuanian beaches exceed the European standard which defines the good condition of beaches by a dozen to several dozen times over. The situation is no better in Latvia either.
Scientists from neighbouring countries have joined forces for the first time in confronting the plastic pollution problem. They are not just talking widely about the results of research carried out on the coast for the past two years, but have also prepared specific guidelines for municipalities, the catering and tourism businesses, and other sectors that would help to achieve positive changes.
Unified monitoring
Both Lithuanian and Latvian researchers have drawn attention to the problem of plastic pollution and have been carrying out studies and calculations for around a decade, highlighting the fact that single-use plastic products and their fragments dominate among the litter found on coastal stretches, while microplastics have long been dominant in the category of micro trash. “Still, there was no general monitoring system that would provide opportunities to have more clarity, compare data and look for the most appropriate solutions to the problem” noted Dr. Arunas Balčiūnas of the Maritime Research Institute of Klaipėda University (KU).
The Interreg V-A Latvia–Lithuania Cross Border Cooperation Programme 2014-2020 and project “ESMIC”
(LLI-525 Estimation, monitoring and reduction of plastic pollutants in Latvian-Lithuanian coastal area via innovative tools and awareness raising) provided opportunities for researchers from neighbouring countries to work together. Klaipėda Science and Technology Park, Latvian Water Ecology Institute at Daugavpils University, Environmental Education Fund in Latvia (FEE Latvia) participated in the activities together with KU.
Innovative approach and methods
When scientists noticed that algae attract garbage and its fragments like a trap, monitoring their accumulation and emissions on the shore became an extremely significant activity of the project. In the implementation of the project, innovative methods were used – beach surveys with drones as well as the analysis of data collected by satellite systems. While processing them, the researchers also integrated artificial intelligence technologies to help model and map algae emissions. “We took, I would say, pioneering steps because in Europe we did not encounter stronger attempts to work on a project on plastic litter topic by combining all these tools,” a KU JTI researcher highlighted.
Consecutive observations were carried out for two years, during which time it was possible to identify the coastal stretches where algal wracks occur most frequently. In Lithuania, the areas in Klaipėda at the northern pier, as well as the northern beach of Šventoji, are exceptional in this regard. In Latvia, algal wracks were primarily recorded between Pape and Jūrmalciems, as well as in the north of the Ventspils pier and in the section between Jūrmala and Bigaunciems.
According to dr. Balčiūnas, it is potentially the first time that the composition of the abovementioned accumulations has been studied so carefully: “Research into garbage entangled in algae has been a kind of grey zone until now because it is quite difficult to carry them out.”
Microplastics are a macro-problem
The research revealed that there was significantly more litter in the algae than in the nearby receding beach sand – the numbers ranged from
2.7 to
6.4 times in the stretches studied. In this context, microplastics are a real ecological timebomb. These particles, which are smaller than 5 mm, are found in extremely large quantities in seaweed: 1 m³ of algae can contain from several tens of thousands to several hundreds of thousands of microplastic fragments. Being highly resistant and created from various chemical compounds, they pose a significant threat to living organisms.
According to scientists, society is already quite aware of the essential sources of plastic: disposable cutlery, packaging and decorations, certain cosmetics ‘rich’ in microplastics, and synthetic textiles. “However, sometimes we don’t even think about other forms of how plastic moves in cities and ecosystems. For example, the mountains of snow cleared from the streets absorb transport pollution, garbage, and microplastics, which melt and flow into the seas and oceans,” the scientist pointed out.
Algae management dilemmas
Bearing in mind the data obtained during the research carried out in Lithuania and Latvia, it is concluded that collecting algae could eliminate quite significant amounts of plastic and other garbage from the marine environment. However, there is no one answer – algae provide both food and shelter for certain species.
Once the decision to remove the algae from the shore has been made, certain dilemmas arise again. In some countries, it is a common practice to use these marine plants as mulch or dune reinforcement, but knowledge of the plastic and microplastics in such accumulations would potentially discourage this.
However, scientists tend to suggest removing algae that stay longer on beaches in the warm season to special sites or for burning. According to researchers, unmanaged algae can serve as a kind of incubator in which microorganisms dangerous to human health grow. It has been determined that three days is the limit for when algae should be removed from beaches visited by vacationers, otherwise, disease outbreaks are possible. The processes are especially intensified in warm weather, but even in autumn when, following stronger winds, people rush to look for amber in the algae wrack, the danger also remains. Therefore, it is necessary to pay attention to hand hygiene and to keep a closer eye on children when exploring the environment.
Balance of discipline and encouragement
While stressing the need to respond appropriately to algal emissions, researchers emphasize the importance of preventative actions to ensure that the sea and beaches stay clean. In December, scientists from Lithuania and Latvia presented an action plan prepared within the framework of the “ESMIC” project, which aims to reduce the use of single-use plastic products in the household, business or during recreational activities.
In preparing this package of tools, which will remain permanently available online, the researchers sought to draw attention to the fact that the involvement of different groups of society is necessary in order to achieve tangible change. “Beach clean-up events are great, but we need to be consistent. You see garbage – pick it up, think about it when buying and selling a souvenir, a product, wrapped in one way or another. The action plan identifies very specific areas and situations where we can and must be proactive in integrating alternatives to single-use plastics,” claimed Balčiūnas.
Coastal municipalities are able to create stricter frameworks for the use of single-use plastic through the mechanisms of issuing permits and licenses for catering, trade sectors, and organizers of major events. The implementation and promotion of the deposit system in bars, festivals, and more drinking water fountains or taps – would also significantly contribute to reducing the level of single-use plastics.
However, restrictions are not the only way of achieving this – it is also important to highlight those who bring about positive changes on their own initiative. Consequently, the “ESMIC” project initiated the “Conscious Choice” awards for organizations and individuals who contribute to the reduction of single-use plastic and educate the public through their activities and example. At the end of this year, the Latvians “Tiamo Grupa”, VšĮ Žemupite, a cafe-bar „Kuršis“ operating in Nida were honoured, along with Bronislava Butkutė, a resident of Šventoji town.
Covered by Euronews
The “ESMIC” team highlights that municipalities, businesses and society do not ignore the problem of plastic – this was evidenced by the involvement of organizations in various events during which relevant information and good practices are shared, as well as cross-sectoral cooperation in the implementation of educational initiatives and exhibitions.
The “My Sea Campaign”, which was organized for the first time in Lithuania this autumn, invited people together with scientists to not only collect and count garbage on the beaches of Karkle, Melnragė, Šventoji and Palanga but also discuss environmental challenges and possible ways to solve them.
The fact that “ESMIC” responded to a truly relevant problem was not only evidenced by the attention of the national media, but also by the assessment of the project’s importance on an international scale – “Euronews TV” came to film the “My Sea Campaign” and was interested in the work of the researchers. The “Smart Regions” TV show created opportunities for Lithuanian and Latvian scientists to share their insights with an audience of 155 countries in seven languages.
