Salt steppes and marshes represent the most valuable ecosystems in the world, providing numerous ecosystem services that are extremely vulnerable to anthropogenic influences. These types of habitat in the territory of Serbia are most dominant in Banat and a significant portion of them is under protection or in the process of becoming protected. The section surrounding the protected areas of Slano Kopovo Special Nature Reserve, Rusanda Nature Park and Okanj Bara Special Nature Reserve with the non-building area of Novi Becej, Kumane, Melenci, Elemir and Taras cadastral municipalities, has been chosen for the analysis. The aim of this paper was to assess the influence of specific anthropogenic factors on the elements of an ecological network using the analytical method that can generate the required results in a manner suitable for presentation to various stakeholders. To achieve this aim, the Leopold matrix model, used for assessing anthropogenic influence on the environment, has been chosen. The specificity of this issue of protecting and preserving elements of an ecological network resulted in the need to isolate and evaluate the factors affecting the preservation of habitats and functionality of ecosystems, unlike the concept of Leopold matrix, which treats all factors as equally important in the process of evaluation. Evaluation results indicate significant effects of historical, perennial manner of using the area and other resources in the non-building area.

Abstract. The anthropogenic environmental changes over the past decade have become global for the entire globe. They deeply penetrate into all components of the environment - the lithosphere, the geomorphosphere, the hydropower and the atmosphere, the soil and vegetation, alter the physical fields of the Earth and the Cosmos, transforming the original natural landscapes into natural and human-made geosystems and endangering human health and life. Especially sensitive to changes are the least protected natural landscapes on the territories of the nature reserve fund - natural monuments, nature reserves, regional parks, national natural parks, natural and biosphere reserves. The article deals with the issues of technogenic influence on the part of the territory of the Dniester Regional Landscape Park - Bistriza-Tlumach’s and Prydniester-Pokutskiy hills of the Prut-Dniester interfluve in Ivano-Frankivsk region. The authors carried out an ecological assessment of the environmental components of the specified territory - geological environment, relief, hydro- and atmosphere, soil and vegetation cover. Recommendations on the reduction of anthropogenic influence by introducing geoinformation technology of environmental protection, its modeling and forecasting are offered. Most of the study area has a generally normal ecological status. There are favorable conditions along the Dniester Canyon, where the oxygen content in the atmospheric air is higher than the average. Within a short distance of the Dniester Canyon from the north-west to the southeast, lanes of satisfactory condition stretch. Within them, five sites of complex ecological status have been identified. The comparison of the obtained data of the ecological assessment of the heights on the right riverside with the adjacent territory on the left riverside of the Dniester – located there National Nature Park “Dniester Canyon” showed that practically all geo-ecological structures of the right bank have their continuation on the left riverside. It follows that the Dnistrovsky Regional Landscape Park should be transferred to the category of nature reserve fund “National Nature Park” and be combined with the National Park “Dnistrovsky Canyon”. Keywords: environmental assessment; geoecological state; environmental components; inter-rivers; hills; anthropogenic influence; GIS-technologies.

Economies all over the world are moving towards a focus on services. Tourism has emerged as a major contributor to economies all over the world. This is why specific focus is being placed on tourism, as Destination Management Organizations (DMOs) concentrate their efforts on tourism. India has been one of the countries where the share of tourism in national income has steadily been increasing. As the national capital, the city of Delhi has a major role to play in the tourist inflow to the country, as well as within the country. Successful tourism marketing requires that the concepts of tourist destination and underlying factors are comprehended in detail. An analysis of the available, pertinent literature on the area shows the manner in which numerous factors come together to form the image of a tourist destination. In fact, it needs to be understood that image formation may be done differently for different consumers. This further necessitates a detailed study of the factors influencing tourist destination image.

AbstractThe following study summarizes the available ethnographical, historical, and archaeological data about the use of fish skin as a material. Fish skin and the methods of its processing are described. The fish skin utilisation accounts from around the world are collected in an organized matter. Afterwards the various factors affecting the use of this material are discussed and some concluding remarks about the further research possibilities are proposed. The use of fish skin does not appear to be based purely on climate, subsistence strategies, or the availability of fish, but also on cultural norms and traditions. Careful hypotheses can be made by using relational analogies, but ultimately a re-examination of museum collections or new archaeological discoveries are fundamental in furthering this field of research.

Extensive urbanization around the world has caused a great loss of farmland, which significantly impacts the ecosystem services provided by farmland. This study investigated the farmland loss due to urbanization in the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) of China from 1980 to 2018 based on multiperiod datasets from the Land Use and Land Cover of China databases. Then, we calculated ecosystem service values (ESVs) of farmland using valuation methods to estimate the ecosystem service variations caused by urbanization in the study area. The results showed that 3711.3 km2 of farmland disappeared because of urbanization, and paddy fields suffered much higher losses than dry farmland. Most of the farmland was converted to urban residential land from 1980 to 2018. In the past 38 years, the ESV of farmland decreased by 5036.7 million yuan due to urbanization, with the highest loss of 2177.5 million yuan from 2000–2010. The hydrological regulation, food production and gas regulation of farmland decreased the most due to urbanization. The top five cities that had the largest total ESV loss of farmland caused by urbanization were Guangzhou, Dongguan, Foshan, Shenzhen and Huizhou. This study revealed that urbanization has increasingly become the dominant reason for farmland loss in the GBA. Our study suggests that governments should increase the construction of ecological cities and attractive countryside to protect farmland and improve the regional ESV.

Odonata species are sensitive to environmental changes, particularly those caused by humans, and provide valuable ecosystem services as intermediate predators in food webs. We aimed: (i) to investigate the distribution patterns of Odonata in streams on a nationwide scale across South Korea; (ii) to evaluate the relationships between the distribution patterns of odonates and their environmental conditions; and (iii) to identify indicator species and the most significant environmental factors affecting their distributions. Samples were collected from 965 sampling sites in streams across South Korea. We also measured 34 environmental variables grouped into six categories: geography, meteorology, land use, substrate composition, hydrology, and physicochemistry. A total of 83 taxa belonging to 10 families of Odonata were recorded in the dataset. Among them, eight species displayed high abundances and incidences. Self-organizing map (SOM) classified sampling sites into seven clusters (A–G) which could be divided into two distinct groups (A–C and D–G) according to the similarities of their odonate assemblages. Clusters A–C were characterized by members of the suborder Anisoptera, whereas clusters D–G were characterized by the suborder Zygoptera. Non-metric multidimensional scaling (NMDS) identified forest (%), altitude, and cobble (%) in substrata as the most influential environmental factors determining odonate assemblage compositions. Our results emphasize the importance of habitat heterogeneity by demonstrating its effect on odonate assemblages.
