EValuating MARine Litter in Greece, “EVMAR” Project

















Marine litter pollution is identified as a major global environmental issue. The amount of litter that accumulates in the marine environment (coastline, surface, water column and seabed) poses numerous threats to the marine environment and the human health, including environmental, social and economic impacts.

The greatest sources of marine macro litter are land-based activities, such as tourism and industry, while marine sources of pollution include activities such as fishing, shipping, mining, etc.









The issue of marine litter is included in the EU Marine Strategy Framework Directive (MSFD) (2008/56/EC) with the aim of taking measures to achieve Good Environmental Status (GES) of the marine environment in the context of the European Environment Policy. More specifically, according to Qualitative Descriptor 10 of the EU MSFD requires EU Member States to ensure that “properties and quantities of marine litter do not cause harm to the coastal and marine environment”. In this regards, Europe is paving the way for litter-free coasts and seas by setting a threshold value of 20 litter items for every 100 metres of coastline to reach GES.


The majority of the Mediterranean population is concentrated along its coastal regions, while its coasts also attract hundreds of millions of tourists annually. Combined with its geomorphology, these factors play a key role in the increased concentration of litter; as a result, the Mediterranean is considered the most polluted European sea.


In Greece, significant fragmented and yet persistent efforts for monitoring marine litter are carried out by a variety of organisations and entities mainly under European projects, since 2015. Although, the country continues to submit reports for the evaluation of Descriptor 10 in the context of EU MSFD, the aforementioned sources of information have been largely ignored, despite potentially providing valuable spatiotemporal information on the issue. 


The EVMAR project focuses on evaluating the marine litter problem in Greece, through the data collected by all actors involved in clean-up and monitoring activities.

The issue of marine litter
The project
In a nutshell, the main aim of the project is to develop a database and a final report including:


The database will be open access and free to everyone interested in further research and analysis, while it will contribute to the prioritization of the pollution prevention actions and plans in Greece by all relevant stakeholders (research centers, NGOs, foundations, businesses, institutions, etc.), as well as in the implementation of the National Waste Prevention Plan.









Whether your organization or you individually participate in coastal or underwater cleanups, your contribution is important in the data collection for the monitoring of aquatic litter in our country!
To help you out, within the framework of the EVMAR project, a monitoring form for data collection was created in accordance with the requirements of the EU Marine Strategy Framework Directive. 


If you are interested in contributing to the research on marine litter in Greece and the Mediterranean, send your scientific publication to the special issue of the project in the international scientific journal MDPI Sustainability entitled “Marine Litter Distribution, Data Collection and Data Harmonization in the Mediterranean Sea”:

Anastasia is an educator, graduated from the Department of Primary School Education, with a master degree in Environmental Education, the Aristotle University of Thessaloniki (Department of Biology in collaboration with the Department of Preschool Education). She has worked in the field of mainstream and special education for 4 years.

At iSea she was coordinating projects related to Aquatic Litter, since 2018. The projects were including the implementation of coastal and underwater cleanups, the active involvement of target groups in tackling the issue of marine litter pollution and the design and implementation of awareness raising campaigns on marine pollution from plastics and microplastics in the Greek seas.

She is now coordinating the “Human and Aquatic Ecosystem” department of iSea, as a Director, designing and implementing educational activities and projects aimed at the active involvement of the public in environmental protection with the aim to redefine our relation with the environment. She coordinated the publication of the environmental education guide for the disabled and is responsible for projects related to the promotion of active participation and the education of citizens for the sustainable management of the environment and the implementation of proper measures aiming at sustainable development.

Her main research interests are related to issues of environmental education and ethics, as well as environmental knowledge and perceptions of citizens on different environmental topics. She’s the Communication Officer of iSea.
