Purpose. To assess of the land use structure of Ternopil city united territorial community and justify the priority areas for its optimization. Methods. Descriptive, comparative-geographical, geoinformation, statistical, mathematical, geoecological analysis and optimization modeling. During the study, special methods were used to determine the anthropogenic load, coefficients of ecological stability and anthropogenic transformation of the Ternopil city united territorial community. Results. Analyzing of the land use structure of Ternopil city united territorial community, it was found that the share of natural lands within it is only 32.5%. The main geoecological problems of the land use of Ternopil city united territorial community are the imbalance of land structure, the lack of master plans of rural settlements and territorial boundaries, the lack of inventory and regulatory monetary valuation of land. The coefficient of anthropogenic transformation of the territory of Ternopil city united territorial community is 6.7, which corresponds to the category of highly transformed landscapes. The coefficient of ecological stability of the Ternopil city united territorial community is 0.28, the territory is ecological unstable with a score of anthropogenic load of 3.22. The geoecological assessment of the land use structure of Ternopil city united territorial community, testified the need to optimize the structure of land and to introduce effective scientifically sound measures. Conclusions. To correct and improve the situation, bringing the territory of the Ternopil city united territorial community to ecological stability, it is necessary to implement optimization measures. In the study we have developed an optimization model of land use in the Ternopil city united territorial community, which provides for the reduction of arable land by 18%, increase in forest cover by 12% and bringing the share of natural lands to the optimal 50%. The implementation of such an approach requires a change in the purpose of individual land plots and the organization of their landscape-adapted use.

The article presents an ecological and geographical analysis of the current state of land resources. The structure of land resources in UTC (United Territorial Community) is dominated by lands of agricultural and forestry use. They occupy the largest areas - 67072.3 hectares, 40004.8 hectares and their share in the structure of the land fund is 57.8%, 34.4%, respectively. The structure of agricultural lands of the district is dominated by agricultural lands, namely arable land. Its area is 67072.3 hectares (97.3%) The largest area of agricultural land is concentrated within the central part of the district. The largest area in the structure of agricultural land is occupied by arable land - 2500 - 3570.8 hectares. In the eastern and south-eastern parts of the district the share of arable land in the structure of agricultural lands is the highest (more than 70%). The share of pastures and hayfields in the structure of agricultural lands is 18.2% and 16.8%, respectively. The smallest share in the structure of lands of perennial plantations (1.6%). The largest areas of hayfields and pastures in the northern and northeastern part of the district, which is due to the natural features of the territory. Peculiarities of forestry use of land resources on UTC area are analyzed. Lands covered with forest vegetation there are unevenly distributed and are mainly subordinated to Brody Forestry. The largest areas of forestry land in the northern and southern parts of the district. Forests in the northern part are located within Male Polissya. Here in the area there is the highest forest cover (45 - 67%). Forest cover in the southern part of the district is 45 - 67%. The structure of lands occupied by forest vegetation is dominated by forest areas (96.0%), including covered with forest crops (71.0%) On the basis of the defined indicators the analysis of ecological stability of lands in UTC is carried out, also the anthropogenic loading on agricultural lands of the area is defined. This figure depends on the area of land of different species. Using the method of Shyshchenko P. H. (1982) we have determined the anthropogenic load on the agricultural lands of the district. This figure depends on the area of the land of different species. Within the district there are spatial differences in this indicator. The greatest anthropogenic load on agricultural land is in the central part of the district. Here the anthropogenic load is more than 6.6 (strongly converted). In the north-western part of the district this indicator is the lowest: 5.2-5.3. On the territory of other village councils agricultural lands are moderately transformed (6.1 - 6.5) The results of the study of the ecological condition of the land resources of the district are presented. The level of plowing, agricultural development of the district is analyzed. The central and southern part of the district is characterized by an unbalanced structure of land use, as there is a fairly high rate of plowing of agricultural land. The share of arable land here is more than 70% of the total area of agricultural land. The average value of this indicator is around 57.7%. The highest agricultural development is in the central part of the district (except for Brody town territorial community), and in the southern part (more than 60%). The maximum indicators of agricultural development are - 86.8-91%. The ecological condition of the land resources of the district was assessed and five groups with different levels of this indicator were identified. The ecological condition of land resources varies from optimal to catastrophic, depending on the ratio of arable land (R) and the share of ecological and stabilizing lands (ESL). Optimal and satisfactory ecological condition of land resources in the region on the area of 40.6%, critical - 25.7%, crisis - 20.4%, catastrophic - 13.3% Land resources are one of the most important resources of the district. In modern conditions, productive agricultural lands should be involved in intensive agricultural cultivation, and the rest should remain in a natural state, which will ensure ecological sustainability and balanced nature management. Key words: land resources, agricultural lands, agricultural development, ecological condition, ecological stability.

Socio Economic Factors

Rural settlements in mountainous regions are a typical process that occurs in many places around the world and have a number of implications on the landscape. Among them is a threat it possesses to the conservation and management of Afromontane ecosystems. This study assessed the socio-economic factors that drive the changes in land use and forest cover and the extent of land use and vegetation cover in and around Magamba Nature Reserve. Focus group discussion, direct field observation and household survey were used to acquire socio-economic information that impacts land use and forest cover. Through the use of Remote Sensing and GIS methods Landsat satellite images of 1995, 2008 and 2015 were employed to identify the extent of the changes in land use and forest cover. The perceived factors for the changes include education level, unemployment, landless/limited, landholding, population pressure, expansion of built-up areas and agricultural land at the expense of other land covers. This study revealed the transformation of natural forest and associated vegetation from one form to another. There was a decrease in natural vegetation from 61.06% in 1995 to 26.02% in 2015 and increase in built-up areas by 6.69% and agricultural areas by 4.70%. This study recommends conservation monitoring and strong law enforcement relating to natural resources so as to promote sustainable use of resources to rescue the diminishing ecosystem services.

AbstractThe present study, for the first time, examined land-use land cover (LULC), changes using GIS, between 2000 and 2018 for the IIT Bombay campus, India. Objective was to evaluate hydro-ecological balance inside campus by determining spatio-temporal disparity between hydrological parameters (rainfall-runoff processes), ecological components (forest, vegetation, lake, barren land), and anthropogenic stressors (urbanization and encroachments). High-resolution satellite imageries were generated for the campus using Google Earth Pro, by manual supervised classification method. Rainfall patterns were studied using secondary data sources, and surface runoff was estimated using SCS-CN method. Additionally, reconnaissance surveys, ground-truthing, and qualitative investigations were conducted to validate LULC changes and hydro-ecological stability. LULC of 2018 showed forest, having an area cover of 52%, as the most dominating land use followed by built-up (43%). Results indicated that the area under built-up increased by 40% and playground by 7%. Despite rapid construction activities, forest cover and Powai lake remained unaffected. This anomaly was attributed to the drastically declining barren land area (up to ~ 98%) encompassing additional construction activities. Sustainability of the campus was demonstrated with appropriate measures undertaken to mitigate negative consequences of unwarranted floods owing to the rise of 6% in the forest cover and a decline of 21% in water hyacinth cover over Powai lake. Due to this, surface runoff (~ 61% of the rainfall) was observed approximately consistent and being managed appropriately despite major alterations in the LULC. Study concluded that systematic campus design with effective implementation of green initiatives can maintain a hydro-ecological balance without distressing the environmental services.

Abstract Globally, the human population is growing, which causes increasing demands on landscapes. Human activity significantly influences the ecological balance, especially in the negative. Ecological stability is the basis for assessments of all environmental conditions and for assessments according to new land uses. The area of interest is evaluated according to both positive and negative factors. There are many methodologies for calculating ecological stability, e.g., Muchová et al. (2009); Řeháčková - Pauditšová (2007); Kupková (2002); Streďanský et al. (1995) and Löw et al. (1984). The aim of this paper is to compare the works of the mentioned authors concerning the ecological stability of the district of Levice (Slovakia), specifically in the municipal cadastre region of Bielovce. The land uses of this territory have changed during some periods. We compared the state of the land uses in the years 1950, 2012 and 2014. During this period, the proportion of arable land increased, and the proportion of forest decreased. In the area of interest, the ecological stability increased, but not as significantly as we expected. The processed data were prepared in GIS.

Depth Analysis

Though on a global scale, for ecological reasons, increased forest cover is universally regarded as positive, on a local scale, the reforestation of arable land may pose threats to cultural landscapes by removing characteristic landscape features. Particularly vulnerable are marginal rural areas, e.g., mountain regions, where most traditional land use systems have survived and which are subject to the most spectacular land use change. The purpose of this article is to draw attention to the issue of the management of forest cover in historical cultural landscapes in mountain territories in Poland within the context of widespread land use change in Eastern Europe. Land cover data were obtained from historical and contemporary aerial photographs, as well as topographic maps from five time points between 1824 and 2016. The study was conducted by means of spatio-temporal forest cover trajectory analysis (LCTA), transition and time–depth analysis, and land cover change calculations that were made by means of ArcGIS. Our research indicates that the rate of change has risen considerably in the last two decades, and the current share of forest cover is much bigger than that reflected in the official data. Eight principal forest cover trajectory types were identified. The biggest area is occupied by woodland of long-term stability. Another large group is constituted by forests created on the basis of arable land and grassland as a result of simple conversion at one point in time, mainly in the years 1824–1886 and 1939–1994. At the same time, a sizeable group is made up by areas that have been subject to unplanned cyclical or dynamic changes during various periods. A very important group is comprised new forests that were created in 1994–2016, predominantly as a result of natural succession, that are often not included in official land classifications. The constant expansion of woodlands has led to a shrinking of historical former coppice woodlands. This indicates that the current landscape management mechanisms in Poland are inadequate for protecting the cultural landscape. The barriers include the lack of intersectoral cooperation and the overlooking of the historical context of landscapes. The present situation calls not only for verification of the existing forest policy but also for increasing the role and engagement of local communities, as well as making comprehensive local development plans, all of which may be helped by the findings of our study and of similar research.

AbstractLand use and land cover (LULC) terrain in Ghana has undergone profound changes over the past years emanating mainly from anthropogenic activities, which have impacted countrywide and sub-regional environment. This study is a comprehensive analysis via integrated approach of geospatial procedures such as Remote Sensing (RS) and Geographic Information System (GIS) of past, present and future LULC from satellite imagery covering Ghana’s Ashanti regional capital (Kumasi) and surrounding districts. Multi-temporal satellite imagery data sets of four different years, 1990 (Landsat TM), 2000 (Landsat ETM+), 2010 (Alos and Disaster Monitoring Constellation-DMC) and 2020 (SENTINEL), spanning over a 30-year period were mapped. Five major LULC categories – Closed Forest, Open Forest, Agriculture, Built-up and Water – were delineated premised on the prevailing geographical settings, field study and remote sensing data. Markov Cellular Automata modelling was applied to predict the probable LULC change consequence for the next 20 years (2040). The study revealed that both Open Forest and Agriculture class categories decreased 51.98 to 38.82 and 27.48 to 20.11, respectively. Meanwhile, Built-up class increased from 4.8% to 24.8% (over 500% increment from 1990 to 2020). Rapid urbanization caused the depletion of forest cover and conversion of farmlands into human settlements. The 2040 forecast map showed an upward increment in the Built-up area up to 35.2% at the expense of other LULC class categories. This trend from the past to the forecasted future would demand that judicious LULC resolutions have to be made to keep Ghana’s forest cover, provide arable land for farming activities and alleviate the effects of climate change.

The Town

The purpose of this study is to provide a comprehensive assessment and comparative analysis of the ecological balance of territories of the three key smalltowns in Kyiv region: Boyarka, Vyshneve and Irpin, as well as tracking the dynamics of ecological stability of the towns` territories in the system of general planning. The following indicators of anthropogenic transformation and natural protection of urban areas were calculatedaccording to known methodsbased on data available from the towns` new Master Plans: coefficients of anthro- pogenic impact, anthropogenic transformation, nature protection, and ecological stability, absolute and relative tension of the ecological and economic state. The rationality of general planning in terms of ecological balance of urban areas is estimated. The study established that the territory of the town Irpin is characterized by moderate anthropogenic impact, while Boyarka and Vyshneve demonstrated a high level of anthropogenic impact. The total area of the environmental fund on the territory of cities ranges from 13.9% (Vyshneve) to 47.5% (Irpin) of the total area of their territories, which is insufficient in all cases. Currently, the territory of Irpin is the most balanced in comparison with other towns. Implementation of the new Master Plans of the cities will improve the ecological balance of the Boyarka and Irpin areas; improvement in Boyarka will be notably extensive due to the expansion of the city boundaries by a threefold increase in the town`s area. The projected general development of Vyshneve will worsen the ecological balance of its territory, despite the foreseen expansion of its boundaries. The pressure from the ecological and economic status of the territories is not balanced by the degree of anthropogenic impact and the potential of the sustainability of nature. For the territory of towns, the potential for sustainability of nature is significantly exceeded and requires the expansion of the environment of a stabilizing group of lands. The areas of towns within the existing boundaries are environmentally unstable, the tensions in the ecological and economic conditions of the territories are not balanced, which testify to their ineffective organization. A significant correlation has been found between the calculated coefficients and the area percentage of the environmental fund of urban areas. The obtained data testifies to the expediency of using the indicated eco-geographical indicators within the system of general planning in order to optimize prospective solutions.

Arable Land Use

The change of primary forest areas into arable land involves the transformation of relief and modification of soils. In this study, we hypothesized that relatively flat loess area was largely transformed after the change of land use due to erosion. The modifications in soil pedons and distribution of soil properties were studied after 185 years of arable land use. Structure of pedons and solum depth were measured in 128 and soil texture and soil organic carbon in 39 points. Results showed that soils of noneroded and eroded profiles occupied 14 and 50%, respectively, and depositional soils 36% of the area. As a consequence, the clay, silt, and SOC concentration varied greatly in the plowed layer and subsoil. The reconstructed profiles of eroded soils and depositional soils without the accumulation were used to develop the map of past relief. The average inclination of slopes decreased from 4.3 to 2.2°, and slopes >5° vanished in the present topography. Total erosion was 23.8 Mg ha−1 year−1. From that amount, 88% was deposited within the study area, and 12% was removed outside. The study confirmed the hypothesis of the significant effect of the land use change on relief and soils in loess areas.

Abstract The paper presents results of the analysis of the land use map compiled for transboundary Lake Khanka Basin using remote sensing data and geoinformation systems. The map reflects the distribution of 12 land categories in Lake Khanka basin in 2017 (arable land, abandoned arable land, paddy field, abandoned paddy field, shrubs and sparse growth, forest land, open pit, settlements, meadows and pastures, wet meadows and marshes, water bodies, forest cuttings and fire sites). The data of land use structure in the whole Lake’s watershed, in its Russian and Chinese parts are given. Data on the distribution of different land categories in the administrative territories of the rank of districts (Russia) and counties (China) are also presented. The analysis of land use structure showed that about 50 % of the Chinese part of the basin is covered by anthropogenically transformed natural complexes. The share of such lands in the territory of Russia amounts to 28 %. Agriculture is the most important factor in the change of natural complexes in Lake Khanka basin. Before early 1990s, the area of farmland had increased in the basin on both sides of the border, after that there was a significant reduction in cultivated lands, which had lasted for 10 years in the territory of China and for 20 years in Russia. Over the past decade, the area of cultivated areas in the basin and adjacent territories has extended again, which indicates an increase of anthropogenic impact and requires serious attention to monitoring of the ecological state of lands in the basin.
