Intensity of land use could be considered as an indicator of rate of anthropogenic impact on landscape (CAI) and the coefficient of ecological stability (CES). These two bio-indexes are based on the land use categories. The CAI coefficient is the ratio of the sum of percentile areas of land characterized by considerable human impact in relation to the sum of percentile areas of lands with low or none anthropogenic pressure. The CES index describes the structure of land use in one unit according to land use categories weighted by given coefficients. The calculation of the complex integral index enables to know the potential of the environment, i.e. a natural resource reserve with a structure that allows self-regulation of ecosystems and expresses the environment's resistance to bearing anthropogenic loads. The aim of the study is to analyze the historical land use changes (in the period of 1845-2016) in rural areas of Southern Poland using bio-indexes such as the anthropogenic impact on landscape (CAI) and the coefficient of ecological stability (CES). The analysis led to the conclusion about the strong dynamics of changes during this period which is largely due to the growth of the percentile areas of lands with considerable human impact especially after the historical transformation in 1989 in Poland. At the same time, the attention should be paid to the land use changes as an effect of growing suburbanization. The results of the study can be used by public authorities, citizens and governing bodies to form a system of measures to calculate environmental potential and modelling changes which ensure the environmental protection and sustainable development of rural areas.

The present paper highlights the importance of hedgerows and enclosures in the mountains of Central Spain. Now, these landscapes have suffered profound variations in terms of agroforestry practices, especially in the Mediterranean mountains where the characteristic multifunctional has largely been lost. The article analyzes land uses changes, dynamics, and their morphological features between the first half of the 20th Century (1956) and the second decade of the present time (2019). The paper was divided into three sections. First, the identification of land uses using orthophotograph and aerial photograph; after that the info was checked with fieldwork. Eleven categories were identified according to the dominant use and land use changes and size of land parcels were taken into consideration. Second, the configuration and the information collected through the type and intensity of change in land uses made it possible to recognise and quantify their distribution and trend between these two dates. Also, the kernel density algorithm available in the Arcgis 10.5 software was used to obtain density and changes in land parcels. Finally, an overview is given of the main role that this agroforestry plays due to the social, ecological, and economic benefits that they provide for allowing sustainable development.

Rapid changes in land use and land cover pattern have exerted an irreversible change on different natural resources, and water resources in particular, throughout the world. Khambhat City, located in the Western coastal plain of India, is witnessing a rapid expansion of human settlements, as well as agricultural and industrial activities. This development has led to a massive increase in groundwater use (the only source of potable water in the area), brought about significant changes to land management practices (e.g., increased fertilizer use), and resulted in much greater amounts of household and industrial waste. To better understand the impacts of this development on the local groundwater, this study investigated the relationship between groundwater quality change and land use change over the 2001–2011 period; a time during which rapid development occurred. Water quality measurements from 66 groundwater sampling wells were analyzed for the years 2001 and 2011, and two water quality indicators (NO3− and Cl− concentration) were mapped and correlated against the changes in land use. Our results indicated that the groundwater quality has deteriorated, with both nitrate (NO3−) and chloride (Cl−) levels being elevated significantly. Contour maps of NO3− and Cl− were compared with the land use maps for 2001 and 2011, respectively, to identify the impact of land use changes on water quality. Zonal statistics suggested that conversion from barren land to agricultural land had the most significant negative impact on water quality, demonstrating a positive correlation with accelerated levels of both NO3− and Cl−. The amount of influence of the different land use categories on NO3− increase was, in order, agriculture > bare land > lake > marshland > built-up > river. Whereas, for higher concentration of Cl− in the groundwater, the order of influence of the different land use categories was marshland > built-up > agriculture > bare land > lake > river. This study will help policy planners and decision makers to understand the trend of groundwater development and hence to take timely mitigation measures for its sustainable management.

Land development analyses play a fundamental role in understanding how land use change shapes the land, depending on continuously changing social, economic, and environmental factors that reflect the interests in space. It is especially important to follow land use changes in rural areas due to their role in food security, environmental hazards, cultural landscape preservation, etc. Continuous analyses and monitoring of land use changes allow for the identification and prevention of negative trends in land use (over intensification, land fragmentation, etc.) that might affect biodiversity, change physical and chemical properties of soil, causing soil degradation, change the spatial balance, stability and natural equilibrium in the rural area. The use of the cross-tabulation matrix methodology was suggested for land use change analyses. The methodology, when the cross-tabulation matrix elements are correctly interpreted, allows us to gain as much insight as possible in the process of land use change. This approach enabled a detailed analysis of vineyards in Goriška brda, Slovenia. It was found that the existing methodology fails to analyse the location of change. For this reason, additional analyses of spatial distribution of change and of the locations where changes in space occur were suggested. The study demonstrated that the land use category of vineyards changes systematically, although seemingly randomly. By comparing land use categories over several time periods, the study determined that the size and speed of change varied across different time intervals. The identified land use changes were assessed in the context of their high pressure on agricultural land. The results of the analyses showed different trends shaping the typical agrarian landscape in Goriška brda.

Improvement of the methodology for determining the anthropogenic pressure on the region's environment, assessment of individual components and the total anthropogenic pressure, analysis of its formation and distribution in Rostov region. The main factors of anthropogenic impact on the environment are divided into four groups and presented in the form of demographic, industrial, agricultural and transport pressure, which, when summed up, give the total anthropogenic pressure. When determining certain types of anthropogenic pressure in the calculations, materials of statistical yearbooks and official data of regional reports on the state of the environment were used. For each type of anthropogenic pressure, indicators of anthropogenic impact and their numerical values were determined. The total anthropogenic pressure was determined by the sum of points. The features of the formation of anthropogenic pressure in Rostov region have been established. In cities with an industrial type of nature management, an increased and average anthropogenic pressure prevails. In rural areas of suburban urbanized zones and the development of mineral raw materials with an agrarian-industrial type of natural resource use, maximum indicators of environmental impact for agrarian areas, increased and average values of industrial, demographic and agricultural pressure have been established. Rural areas with an agrarian type, remote from industrial centers, are characterized by an increased agricultural pressure, lower and low values of the total pressure.

With the increasing number of megacities, the constant expansion of their borders, and the often chaotic, unreasonable land-use planning, even those sites with potential recreational use suffer from enormous anthropogenic pressure. Defining the limits of ecosystem stability is one of the most important scientific research, which allows setting permissible anthropogenic impact in the land cadastre zoning of megacities. This investigation presents the integral assessment of net anthropogenic load on the environment and boundaries of the natural soil geochemical background change.

Abstract Historical land use information is essential to understanding the impact of anthropogenic modification of land use/cover on the temporal dynamics of environmental and ecological issues. However, due to a lack of spatial explicitness, complete thematic details and the conversion types for historical land use changes, the majority of historical land use reconstructions do not sufficiently meet the requirements for an adequate model. Considering these shortcomings, we explored the possibility of constructing a spatially-explicit modeling framework (HLURM: Historical Land Use Reconstruction Model). Then a three-map comparison method was adopted to validate the projected reconstruction map. The reconstruction suggested that the HLURM model performed well in the spatial reconstruction of various land-use categories, and had a higher figure of merit (48.19%) than models used in other case studies. The largest land use/cover type in the study area was determined to be grassland, followed by arable land and wetland. Using the three-map comparison, we noticed that the major discrepancies in land use changes among the three maps were as a result of inconsistencies in the classification of land-use categories during the study period, rather than as a result of the simulation model.

Cutaneous Leishmaniasis transmission in the New World is observed in areas with rich sand fly species’ faunas. The diversity and composition of sand fly species can change in response to seasonal weather and land use changes. Here, we present results from a two-year-long study where we collected, using Centers for Disease Control (CDC) light traps, sand flies from two rural areas, Las Pavas (LP) and Trinidad de las Minas (T) in western Panamá. Over 710 trap-nights, we collected 16,156 sand flies from 15 genera and 35 species. We identified 34 species in T, and the most abundant species collected was Nyssomyia trapidoi (Fairchild and Hertig, 1952) (n = 2278, 37%), followed by Psychodopygus panamensis (Shannon, 1926) (n = 1112, 18%), and Trichopygomyia triramula (Fairchild and Hertig, 1952) (n = 1063, 17%). In LP, we identified 26 species, and the most abundant species collected were Ty. triramula (n = 4729, 48%), and Ps. panamensis (n = 3444, 35%). We estimated a higher species’ richness in T (Chao2 ± S.E.: 36.58 ± 3.84) than in LP (27.49 ± 2.28). In T, species’ richness was significantly higher in the rainy season, but no seasonal differences were observed in LP. Species’ assemblages were nested in the two areas. Phlebotomine sand fly species’ abundance increased at the two sites during the rainy season. Our data suggest that seasonality is more important than land use as a factor driving sand fly species’ diversity at the studied sites.

The forms and types of residential areas are conditioned by historical and socio-economic conditions of the country. Development of industrial relations have evolved and accommodation system in rural areas. Tenure and land-use changes played the most important role in the development of rural land. Modern rural residential areas formed under the influence of certain particularities characteristic to one or the other region of the country. The article analyzes five major periods of landscape development, land reform factors which had influence on residential areas formation, as well as the problem of decay of residential areas and the factors influencing the development of existing settlements.
