    Abstract: Razim Lake is the biggest of Romania’s freshwater lakes and along with other basins as Golovita, Zmeica and Sinoie constitutes a system of great ecological significance, playing also an essential role in the supply of water for irrigation, fishery exploitation, farming, flood prevention, recreational navigation and water tourism. Due to their importance, the environmental conditions in the Razim - Sinoie coastal lakes have attracted an increased public attention in contemporary society. To assess the levels, dissemination and potential sources of contamination in the above-mentioned lagoon system, random sampling was used to collect water and sediment samples from every lake and several analytical techniques were performed to investigate their environmental characteristics. The results obtained from this study indicated that, in water, concentrations of various physico-chemical parameters are, mostly, in agreement with correlated environmental standards. Slight variations and/or occasional exceeding of the maximum admissible limits were generally limited to small areas showing levels that would not warrant special concern. In sediments, the mean concentrations of some specific trace metals were below the levels of potential effect. Benthic samples revealed 31 taxa belonging to 16 zoo-benthal subdivisions. The results of this study showed good ecological status despite local several natural and anthropogenic stressors as fishery exploitation, farming, recreational navigation and water tourism.

    Abstract: Using airborne drones to monitor water quality in inland, transitional or coastal surface waters is an emerging research field. Airborne drones can fly under clouds at preferred times, capturing data at cm resolution, filling a significant gap between existing in situ, airborne and satellite remote sensing capabilities. Suitable drones and lightweight cameras are readily available on the market, whereas deriving water quality products from the captured image is not straightforward; vignetting effects, georeferencing, the dynamic nature and high light absorption efficiency of water, sun glint and sky glint effects require careful data processing. This paper presents the data processing workflow behind MapEO water, an end-to-end cloud-based solution that deals with the complexities of observing water surfaces and retrieves water-leaving reflectance and water quality products like turbidity and chlorophyll-a (Chl-a) concentration. MapEO water supports common camera types and performs a geometric and radiometric correction and subsequent conversion to reflectance and water quality products. This study shows validation results of water-leaving reflectance, turbidity and Chl-a maps derived using DJI Phantom 4 pro and MicaSense cameras for several lakes across Europe. Coefficients of determination values of 0.71 and 0.93 are obtained for turbidity and Chl-a, respectively. We conclude that airborne drone data has major potential to be embedded in operational monitoring programmes and can form useful links between satellite and in situ observations.

    Abstract: Educational institutions, especially universities, have been major pillars in societal transformation throughout society’s history. They have been leading change through their discoveries, research results, and foremost, their example. Nowadays, universities have once again taken the role of leading change in a world that is profoundly determined to have a sustainable approach to life, paying attention to the long-term effects of their actions. In this sense, under the impact of deep digitalization, this paper advocates for the sustainable development of universities regarding campuses’ expansion to rural areas. Moreover, it was demonstrated that sustainable development can be achieved by embracing the potential of digitalization. Based on a multicriteria analysis of the Romanian development regions, the research results showed that the rural area might be a welcoming environment for campuses of sustainable universities, based on digitalization at the level of the rural area in all activity fields, which is an initiative that would generate positive outcomes on many levels for different types of stakeholders, such as universities, students, staff, rural area population, and the nearby business environment. Future research aims to approach and explain the compounded effects of such an approach in depth and establish an even clearer picture of how beneficial such an expansion could prove to all factors considered under a knowledge-based society with digitized information as a vital pillar.

    Abstract: Nature-based solutions (NBS) are increasingly being promoted because they can solve different pursued aims together with providing an additional array of multiple ecosystem services or co-benefits. Nevertheless, their implementation is still being curbed by several barriers, for example, a lack of examples, a lack of finance, and a lack of business cases. Therefore, there is an urgent need to facilitate the construction of business models and business cases that identify the elements required to capture value. These are necessary to catalyze investments for the implementation of NBS. This article presents a tool called a Natural Assurance Schemes (NAS) canvas and explains how it can be applied to identify business models for NBS strategies providing climate adaptation services, showing an eye-shot summary of critical information to attract funding. The framework is applied in three case studies covering different contexts, scales, and climate-related risks (floods and droughts). Finally, a reflective analysis is done, comparing the tool with other similar approaches while highlighting the differential characteristics that define the usefulness, replicability, and flexibility of the tool for the target users, namely policymakers, developers, scientists, or entrepreneurs aiming to promote and implement NAS and NBS projects.

    Abstract: The objective of this study is to provide an updated account of the distribution history of two invasive molluscs, Corbicula fluminea and Dreissena polymorpha, both in Europe and worldwide. In addition to this, the study also intends to review their ecological requirements to gain a better understanding of their invasive potential and distribution dynamics. Specifically, the study focuses on updating the distribution and ecological characteristics of these freshwater bivalves in the lower sector of the Danube River and the lakes of the Danube Delta. The purpose is to better understand their invasive and distribution dynamics and to develop effective measures to limit their spread in the future. To achieve this, environmental proxies such as sediment particle size and Total Organic Carbon (TOC) concentrations were used to assess their tolerances. However, the results did not show a significant correlation between the densities of these bivalves and the analyzed environmental parameters. Despite this, the species were found in high densities and formed well-developed benthic communities in some stations. The study contributes to the understanding of the invasiveness of these bivalve species and their distribution range dynamics. Nonetheless, further investigation is required to fully comprehend the role of environmental parameters in their distribution. The study covers the period between 2010 and 2020 and focuses on the lower Danube River sector and Danube Delta.

    Abstract: There is a growing interest worldwide on the potential of nature-based solutions (NBSs) as measures for dealing with water-related risks while producing multiple co-benefits that can contribute to several societal challenges and many of the sustainable development goals. However, several barriers still hamper their wider implementation, such as mainly the lack of stakeholders’ engagement and the limited integration of stakeholders’ knowledge throughout the phases of NBS design and implementation. This is a crucial aspect to guarantee that the multidimensional implications of NBSs are adequately understood and considered by decision-makers. Innovative methods and tools for improving NBS design and supporting decision-makers in overcoming the main barriers to implementation, ultimately enhancing their effectiveness, are therefore needed. The present work proposes a combined approach based on the integration of fuzzy cognitive maps, hydraulic modeling, and participatory Bayesian belief networks aiming to facilitate the stakeholders’ engagement and the knowledge integration process in NBS design and assessment. The approach was developed and implemented within the NAIAD project in the Lower Danube demo site, specifically oriented to support the process of the Potelu Wetland restoration. First, fuzzy cognitive maps are adopted as a problem structuring method for eliciting stakeholders’ risk perception and problem understanding, and for constructing a causal model describing the system as a whole, with specific attention to the expected role of the NBS in reducing flood risk and addressing the key local challenges. Second, hydraulic modeling is used to analyze the effect of extreme floods starting from the retrospective analysis of a specific event and to model the potential benefits of risk reduction measures. Last, a Bayesian belief network is used to support the model integration process and a scenario analysis with a user-friendly tool. The whole process can be replicated in other areas and is particularly suitable to support an active engagement of stakeholders (both institutional and not) in the process of NBS design and assessment.

    Abstract: The East-West Romanian labor market disparities occurred and have been amplified by the rapid regional economic progress based on entrepreneurial spirit, corroborated with specific market opportunities. The end of the second millenium marked the liberalization of the Romanian labor market due to the transition from the planned economy to the open economy. As a result of this transition, the economic globalization phenomenon occurred and shaped Romania, both positively and negatively. However, at the beginning of the twenty-third century, some Romanian economic sectors are facing serious issues as far as the labor force is concerned, or rather the lack of labor force. The objective of this research paper was to explore the EastWest Romanian labor market disparities under the influence of globalization and entrepreneurship through the lens of socio-economic indicators. Results confirm that the Eastern Romania is encountering serious labor issues with direct effect on particular economic sectors.

    Abstract: he economic development that preceded the economic crisis of 2008 has caused a lack of staff on the labor market, in particular of specialists in certain key areas, in all developed countries. The acute shortage of skilled staff at European level is also found among Romania, where companies play an important role in defining society at local and regional level. Romania has about 19 million people, of whom only 5 million are full-time employees, and the labor market estimates a shortage of more than 1 million employees in 2021, according to a study by audit and consulting firm PwC. In this respect, it was considered appropriate to analyze two development macroregions in Romania, which register smallest, respectively the and largest population in terms of national level. The general objective of the research is to identify the macroregion that has a greater potential for making private and even public investments. In this way, the method of multicriteria analysis at the level of applied methodology was used, so that current and future entrepreneurs can observe a clear delimitation of the two opposite areas of the country, regarding the existing potential on the labor market. Being positioned in opposite parts of the country, Macroregion Two and Macroregion Four each have certain specific economic characteristics, which can lead to a sustainable maroregional strategy for on the stability and prosperity of the labor market.
