    Identifying the sources and the contributions of inland sediment and litter pollutants to enhance the Black Sea through nature-based solutions
    (Springer Nature, 2023) Zaimes, George N.; Koutalakis, Paschalis; Gkiatas, Georgios; Iakovoglou, Valasia; Marinescu, Mirela; Ristea, Oana; Ghulijanyan, Andranik; Gevorgyan, Luiza; Kuharuk, Ecaterini; Trombitsky, Ilya; Tüfekçioğlu, Mustafa; Yavuz, Mehmet; Tüfekçioğlu, Aydın; Duman, Ahmet
    The Black Sea is considered one of the most degraded regional seas. Efforts have been made to improve the conditions of the Black Sea, but little focus has been on the inland pollutants and litter, specifically from the rivers and streams that end in the Black Sea. Streams and rivers are significant sources of sediment and litter. This study aimed to identify the primary sources of sediment and litter and their contributions. This will help to suggest the optimal nature-based solutions to mitigate pollution sustainably. The study has five pilot areas in Greece, Romania, Armenia, Moldova, and Turkey. This will allow us to investigate different riverine ecosystems around the Black Sea and the implementation of different nature-based solutions. Surface and stream bank erosion methods are applied at different scales (plot and watershed) to estimate their contributions to the Black Sea. Traditional (runoff plots erosion pins) and innovative methods (laser scanning, unmanned aerial vehicles) are utilized. This way, areas with the highest erosion or litter will be targeted, and the optimal nature-based solutions based on the specific characteristics of these areas will be implemented.

    Perspectives on protected area and wildfire management in the Black Sea region
    (Northeast Forestry Univ, 2020) Zaimes, George N.; Tsioras, Petros A.; Kiosses, Chrysovalantis; Tüfekçioğlu, Mustafa; Zibtsev, Sergiy; Trombitsky, Ilya; Uratu, Razvan; Gevorgyan, Luiza
    Protected areas are necessary for the conservation and enhancement of biodiversity. Wildfires are major threats to forests and other natural areas, because they may cause irreversible damages. The aim of this study was to analyze the perspective of experts (N = 284), from six countries of the Black Sea, on the current status and problems of protected areas and wildfires. Understanding their points of view could enhance future management on these issues in the region. Data collection was carried out for 9 months, using a web-based questionnaire. Wildfires were perceived as a serious problem in Turkey, Armenia and Greece but as a substantially less serious problem in Romania, Ukraine and Moldova. In Greece, Armenia, and especially Ukraine, the current designated protected areas are considered sufficient to maintain biodiversity, while in Romania, Turkey, and especially Moldova, more areas should be designated as protected. A major need in all countries (except for Turkey) is the increased use of information and communication technologies for both wildfire suppression and protected area management. Experts were divided on whether wildfire suppression and management of protected areas are interconnected. However, there is growing awareness of the adverse impacts of climate change in protected areas and the frequency of wildfires in the future. The most frequently suggested measures to alleviate these impacts were: changes in forest management and increasing public awareness for wildfire suppression, along with changes in forest management and increased staff training to enhance protected area conservation.
