Abstact This empirical study aims to investigate the dynamic response of renewable energy consumption to long-run disequilibrium and short-run impact of tourism development and agricultural land usage for the period of 1995 to 2014 in 16 Coastline Mediterranean Countries. For this reason, a dynamic Autoregressive Distributed Lag approach is employed in a multivariate and two-model framework such that carbon emission and gross domestic product are being controlled for in the models. Significantly, there is evidence of a joint impact of tourism development and agricultural land usage on renewable energy consumption. With a speed of adjustment of 21.6% from short-run disequilibrium to long run, their respective panel elasticities are 0.33 and negative 1.60 in the long run. Significant evidence shows that nine of the Coastline Mediterranean Countries have tourism development as a short-run factor while Slovenia and Cyprus exhibit a short-run common factor. Also, Granger causality evidences from carbon emission, gross domestic product and tourism development to renewable energy are all with feedbacks. However, Granger causality from agricultural land usage to renewable energy is without feedback. In the region, effective policy implementations through the collaborative effort of stakeholders will ensure a sustainable renewable energy development amidst agricultural and tourism activities.

Working Definition

This paper examines the Stevens linear and quadratic programming formulations of von Thünen's analysis of agricultural land usage (Stevens, 1968). The first section contains a description of the Walras—Wald version of general economic equilibrium, plus a working definition of the expressions: general equilibrium sketch, paticularised general equilibrium sketch, and partial equilibrium sketch. [The author's distinction between a sketch and a model is explained in Macmillan (1978).] In section 2, von Thünen's assumptions, Stevens's (first) revised version of those assumptions, and Stevens's linear programming model are described. In section 3, the relationship between the Stevens linear programming model and the Walras—Wald model is examined. The fourth section contains a description of Stevens's approach to the relaxation of von Thünen's assumption of infinite demand elasticity, and a comparison of that approach with the so-called partial equilibrium approach to the same problem. It is claimed that this comparison is of some general, methodological interest. Section 5 contains the paper's conclusions.

The article presents the analysis of the Associations of Gardeners of Lithuania, the undergoing changes in their territories. Since the establishment of the amateur gardening comprising 56 associations, there has been a tendency of privatizing a great number of agricultural land parcels owned by the amateur gardeners; the traditional gardening tends to be substituted for a single family housing. The objective of the article is to discuss the current situation in the territories allocated for the amateur gardens, to point out the tendencies of their future development taking into consideration different regions of the country and to assess the problems concerning land usage and management. The associations of gardeners comprise 216932 individual gardeners; they manage 228673 land parcels owned by them, which totally occupy 20714 ha. The major part of the land allocated for the associations of gardeners is the privatized land by the members of the associations, i.e. the territory makes 70.4 %. The survey of the experts of the municipalities on the current state of the territories of the amateur gardens and the assessment of the particular locations of gardens, presented the results, which confirm that the majority of the associations of gardeners failed their main purpose and new development tendencies appeared depending on their geographical location. The associations of gardeners has come across with a great number of problems on territorial planning, engineering communication services, and services maintaining the needs of the associations, the expansion as well as development of these areas.

AbstractRecent research at Soba focuses on the tangible and intangible heritage of the medieval capital of Alwa kingdom, whose remains cover approximately 275 ha. About 222 ha of this area has been built up or transformed into agricultural land in the past 30 years. An ethnographic survey was also carried out in the built-up area to understand how the residents engage with the archaeological heritage and material remains. The undeveloped area of the capital (53 ha) was the focus of interdisciplinary archaeological fieldwork conducted in 2019 and 2020. A large-scale geophysical survey, using a fluxgate gradiometer and ground-penetrating radar, was initiated in the undeveloped area, and excavation trenches were opened to verify distinctive magnetic anomalies. Along with the ethnographic and geophysical data, the study of the pottery, burials, and stratigraphic sequence (supplemented with radiocarbon dates) provides new insights into the spatial organization of the medieval capital.

Allocation Process

Agricultural location theory deals with both the location — allocation process of land uses by farmers, and the spatial organization of agricultural land uses. The major term in its classical versions is economic rent relating to some form of surplus. Ricardo's theory emphasized the physical qualities of land and urban demand as major determinants in rent production. Von Thünen's theory emphasized distance from farm to market as well as transport costs, yield, market prices, and production costs as rent determinants. Modern versions of the theory provided simple models which relate explicitly to transportation costs. The theory has been criticized mainly for its many limiting assumptions.

We studied the socio-spatial organization of Eurasian badgers (or European badgers), Meles meles (L., 1758), in a low-density population (estimate 1.8 badgers/km2) inhabiting a semi-rural area of western Switzerland. For this purpose, 8 badgers (5 males and 3 females) were caught at 5 different main setts and were radio-tracked between May 1994 and November 1996. The size of individual home ranges varied from 0.27 to 3.74 km2 (1.69 ± 1.33 km2 (mean ± SD), n = 8, 100% MCP), seemingly according to local variations in habitat productivity. Individual home ranges were spatially stable, but their size decreased significantly during winter (0.26 ± 0.42 km2, n = 7, 100% MCP). Badger social units consisted of 1–5 adults and (or) subadults (2.2 ± 1.5 animals, n = 9) and their yearly offspring. Group-range size varied from 0.57 to 3.74 km2 (2.12 ± 1.30 km2, n = 4) and seemed to be influenced by the spatial distribution pattern of food resources. Indeed, each group range encompassed approximately the same surface of agricultural land (about 0.60 km2). Territories were not well marked, some group ranges partly overlapped. Latrines, which were not numerous and principally located inside rather than along borders of group ranges, were only used irregularly or sporadically. This prompts us to encourage the reconsideration of the role of territorial behaviour in promoting group formation in Eurasian badgers.

Dry Steppe

The agricultural use of land resources in the dry steppe regions of Northern Kazakhstan has undergone significant changes over the past century and continues to change at the present time. The middle position in the region is occupied by the Akmola region, one of the leading agricultural regions, where 9.3 % of the country’s gross agricultural output is produced. The main branches of agriculture in the region are grain farming and dairy and beef cattle breeding. The study of the change in the ratio of the areas of arable and pasture lands, the changes that have occurred in the state of agricultural landscapes as a result of long-term use is important for the further development of the agricultural industry in the region. Using the example of the Astrakhan district of the Akmola region, typical for the dry steppe zone, an analysis of changes in the structure of agricultural land from 1953 to 2020 was carried out. with the help of a series of digital maps compiled from detailed maps of scientific reference atlases of Northern Kazakhstan in 1964, 1970, remote sensing data of different times, archival materials and data of modern statistics. The resulting maps visualize significant changes in cropland areas within the study area over the past 70 years. Seven main periods were identified, during which the most significant changes in the structure of land use occurred as a result of political, economic and natural factors. During the years of development of virgin and fallow lands, the highest rates of increase in arable land were observed, which continued on a smaller scale until 1990. The period from 1991-1999 characterized by a large-scale reduction of arable land and abandonment of pastures. This was followed by two periods of gradual restoration of the use of arable and rangelands. Compiled comprehensive map of the dynamics of agricultural land use from 1988 to 2020 made it possible to identify spatial and temporal patterns in changes in the structure of agricultural land use, to determine to which specific natural types of lands the abandoned lands belonged and to which restored ones. Spatial analysis showed that over the past 30, more than half of the area’s area has not changed the type of land use. The results obtained are used to select the optimal ratio of arable and pasture lands in the structure of agricultural land use, as well as to develop a strategy for the rational use of agricultural land in the zone of risky farming.

The zones of ecological trouble cover about 15% of the territory of Russia, where the main production capacities and the most productive agricultural lands are concentrated. The Samara region is characterized by a distinct natural zonality from a typical forest-steppe in the North with a forest cover close to 30%, to an open dry steppe in the South with a natural forest cover of only 0.1...0.2%. The article presents an analysis of land use in the Samara region on the example of the Borsky municipal district. Research methods include environmental analysis and statistical data analysis.The article presents an analysis of the land use of the Borskiy municipal district. During zoning, the territory of the district is divided into the northern, central and southern parts. Assessment of environmental and economic parameters showed heterogeneity of the territory and the need for detailed consideration of climatic, soil, economic conditions in the design of landscape optimization systems, even in the municipal area. In general, the district's land fund experiences an average anthropogenic load, the ecological stability of the territory as a whole is characterized as unstable stable. In comparison with other areas of the Central MES, the municipal Borskiy district belongs to the category with an average ecological intensity with a stabilization index of 0.59 units due to the beneficial influence of the Buzuluksky area.
