Marginal land is the area remaining in agricultural use, which is not suitable for food production because of its unfavorable ecological, anthropological, and economic conditions. A certain amount of such land exists in mountainous areas. An analysis was undertaken on the example of the Polish Sudeten mountain range of energy use. The study aimed to estimate the biomass potential for the efficient use of agricultural land in mountain areas. The characteristics of the Polish Sudeten Mountains mountain range were characterized using Geographic Information System (GIS) methods. The Polish Sudeten Mountains covers an area of 370,392 ha, 95,341 ha of which is arable land, 35,726 ha of which is class 5 bonitation land with a northern exposure of 19,030 ha and southern exposure of 16,696 ha. Depending on the sowing structure, we can obtain 331,639 tons/year of dry biomass (Miscanthus sacchariflorus on the southern and Helianthus tuberoses on northern exposure). Fertilization levels will significantly affect low yielding plants, and water stress significantly reduced yields in all cases. Due to the steep slope of the 5th-grade halves and intensive rainfall in the mountain region, the establishment of perennial plantations is recommended. The research shows that after the first year of cultivation, yields of 9.27 tons/ha of dry matter can be obtained with a low yield of trees, shrubs and perennials.

Rehabilitation Measures

The changes in the density of pollution Cs-137 of arable land, hayfields and pastures in the south-west of the Bryansk region are considered. It is noted that the cleansing process is slow, so reha-bilitation measures are the main way to reduce the specific activity of the radionuclide in crop and feed production. The paper presents algorithm of calculation. Economic efficiency of agrotech-nical and agrochemical rehabilitation of arable land is estimated on results of stationary field ex-periments. The most economically expedient rehabilitation measures for various soils and densi-ties of radioactive contamination are established: 1) soil sod-podzolic sand, contamination densi-ty 137Cs 871 kBq/m2 – in crop rotation barley, clover, corn, winter rye, oats application of lime flour in a dose of 2.1 t/ha + NPK; 2) sod-podzolic sandy loam soil, contamination density Cs-137 2516 kBq/m2 – in crop rotation winter rye, potatoes, barley + perennial grasses, clover + timofeevka of the first year of use, clover + timofeevka of the second year of use introduction of phosphorite flour in a dose of 288 kg/ha + NPK; 3) sod-podzolic soil light loamy, contamination density Cs-137 901 kBq/m2 – in crop rotation potatoes, barley, corn, oats + perennial grasses, clover + timofeev-ka of the first year of use, clover + timofeevka of the second year of use, winter rye application of one-and-a-half doses of phosphorus-potassium mineral fertilizer in combination with one dose of nitrogen mineral fertilizer (NP1,5K1,5); 4) sod-podzolic soil is light loamy, contamination density Cs-137 1224 kBq/m2 – in crop rotation potatoes, barley, corn, oats + perennial grasses, clover + timofeevka of the first year of use, clover + timofeevka of the second year of use, application of dolomite flour in a dose of 3 t/ha + manure 120 t/ha + K600. For natural meadows, where rehabili-tation measures are not used, an adaptive method of agroecological use is proposed. With a con-tamination density of Cs-137 of more than 185 kBq/m2, it is advisable to harvest a green mass of canary grass stands in the central parts of the floodpubs, which accumulate less radionuclide, grazing animals along the otava is prohibited in order to protect them from radioactive substanc-es that may enter their body with sod and shallow soil. In “near the river bed” and “near terrace” parts of the waterprays, where grass stands accumulate much more Cs-137, grazing of animals is prohibited.

Using Data

Smallholder agriculture is a major source of income and food for developing nations. With more frequent drought and increasing scarcity of arable land, more accurate land-use planning tools are needed to allocate land resources to support regional agricultural activity. To address this need, we created Land Capability Classification (LCC) system maps using data from two digital soil maps, which were compared with measurements from 1305 field sites in the Dosso region of Niger. Based on these, we developed 250 m gridded maps of LCC values across the region. Across the region, land is severely limited for agricultural use because of low available water-holding capacity (AWC) that limits dry season agricultural potential, especially without irrigation, and requires more frequent irrigation where supplemental water is available. If the AWC limitation is removed in the LCC algorithm (i.e., simulating the use of sufficient irrigation or a much higher and more evenly distributed rainfall), the dominant limitations become less severe and more spatially varied. Finally, we used additional soil fertility data from the field samples to illustrate the value of collecting contemporary data for dynamic soil properties that are critical for crop production, including soil organic carbon, phosphorus and nitrogen.

The land use has undergone some changes in the last 30 years, by reducing the areas with arable land, converting multi-annual plantations into other categories of land, etc. According to the current mode of land use, the Northern Development Region has a pronounced agricultural profile - 80.3% of the total area represents agricultural land. The spatial differentiations regarding the morphological and agro-climatic conditions allowed the identification within the region of areas with agro-forestry and agro-pastoral specializations.

The article is devoted to substantiating the prospects for increasing the marginal volumes of agricultural production for export in the next four years. Two scenarios of such production are considered: 1) expansion and 2) intensification of the use of land resources. As part of the development of the first scenario, an analysis of the distribution of unused agricultural land, including arable land, by federal districts was carried out. Also, based on the forecast of the introduction of additional annual volumes of acreage in the subjects of the Federation, the calculation of additional volumes of agricultural production, which can be expected in the next four years, was carried out. The analysis of data on the increase in the yield of export-oriented crops over the past five years has been carried out, in the framework of the second scenario, the calculation of the projected additional yield due to the intensification of agriculture is presented. The results of the study indicate that the intensification of agriculture will have the greatest impact on the growth of production and export of agricultural products in the near future.

The distribution of the Sosnovsky hogweed on the southern border of the secondary range in the European part of Russia on the example of the Kursk Region is investigated in the work. It is revealed that Sosnovsky hogweed grows mainly in the western part of the Region in the vicinity of places where it was cultivated in fields in the second half of the twentieth century. The analysis of invader occurrence in anthropogenic and natural ecosystems of the Region revealed patterns of distribution that are characteristic of invasive species at initial stages of their secondary range formation: most of the foci are present in anthropogenic and semi-natural habitats; medium-sized foci predominate (from 100 sq. m. to 1 ha); the greatest number of foci was found in the areas located along roads. The intensive distribution of hogweed in settlements of the Region, especially with pronounced depopulation processes, was revealed. Among natural and semi-natural habitats, most of the foci were found along the banks of reservoirs. In forests, hogweed is found mainly in small groups of vegetative rosettes on the outskirts, with the exception of areas with a strong anthropogenic impact, where multiple foci with generative shoots are formed. At present, hogweed is not found on arable land due to the intensive cultivation of agricultural land in the Region. Plant communities with Heracleum sosnowskyi in the Kursk Region are represented by 4 syntaxons: association Urtico dioicae-Heracleetum sosnowskyi , association Rudbeckio laciniatae - Solidaginetum canadensis variant Heracleum sosnowskyi , association Chelidonio-Aceretum negundi variant Heracleum sosnowskyi , derivative community Heracleum sosnowskyi [ Agropyretalia intermedio-repentis ].

Purpose. To characterize the methodological approaches that we develop in the formation of a system of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes and to show the results of their implementation on the example of the territory of some agricultural enterprises of the Kharkiv region. Methods. Cartographic, geoinformation analysis, calculation, statistical and mathematical. Results. Some results of the work of the collective on the issues of information support for the creation and maintenance of the functioning of modern sustainable agricultural landscapes. Namely, verification of erosion models, studies of the functionality of shelter belts, the formation of an agroeconet (an extensive network of natural and quasi-natural landscapes) on agricultural land massifs, which ensures the maintenance of stable functioning of meso and macrolevel agrolandscapes, as well as the experience of using magnetic prospecting methods to verify the results of mathematical modeling of erosion processes. Conclusions. A number of methodological approaches to information support of the formation of sustainable agricultural landscapes in the natural and socio-economic conditions of Ukraine have been developed. They relate to the functioning of anti-erosion measures of permanent action, the processes of modern transformation of agro-landscapes, the ecological impact of erosion processes on the environment. The connection between the length of forest belts per unit of arable land and soil erosion is shown. A methodical approach has been developed to estimate the amount of soil washed away from arable land and to calculate the measures necessary to eliminate its harmful effects on the environment.

The aim of the work was the landscape analysis of agricultural geographical landscapes in the Altai Territory and elaboration of measures aimed at the rational use of agricultural lands. Environmental and landscape (landscape) approach became the main method of scientific research used in the analysis of modern agricultural landscapes. The cartographic method, using GIS-technologies, made it possible to digitize the obtained materials. Synthesized maps of agro-ecological, natural and other zoning of territories are based on topographic, soil, geobotanical and other thematic maps made during land surveying during the field survey. Retrospective analysis, induction and deduction methods,analysis and synthesis, as well as the abstract-logic method were also used in the work. Our main result was the analysis of land use territory for agricultural enterprise in municipal district of Altai Krai. Exploration of lands indicates a pronounced plant-growing specialization of JSC “Pobeda” with a developed animal breeding direction. Limiting factors affecting the rational use of land are natural and climatic conditions, terrain,unsystematic anthropogenic activity and, as a result, the development of erosion processes. The degree of eroded and deflated arable land is more than 50%, hay and pasture lands are also very unstable. Landscapes have been typified, based on which eleven types of land have been identified and their geomorphological description has been carried out. The first five types of land can be used for agricultural production with limitations compensated by crop technology and erosion control measures, the sixth and seventh types require grassing and, in some cases,conservation, the eighth and ninth types can be partially used for pasture and area valorization; the remaining two are not suitable for agricultural use but should be potentially used for planting and forest management. As a result of the presented transformation of agricultural lands, the structure of cultivated areas has changed. The area of arable land decreased by 877 ha, and of pastures by 365 ha,while the area under hayfields, fallow lands, and forest lands increased by 295, 191, and 875 ha respectively. Low-productive lands were withdrawn from agriculture. We suggested that the sustainability of agricultural land use was mainly caused by the reduction of anthropogenic load and increase in ecological equilibrium of the territory.

The largest countries of the world are inevitably involved in various global processes, both natural and socio-economic. These countries have common features and characteristic differences in the state of their territorial resources; the study of these characteristics is of interest for the global prospects of sustainable development. A large territory provides a variety of natural conditions and resources for the country; however, not in all countries it is possible to effectively use them in the economy throughout the all country. An analysis of their territorial resources was carried out for the six largest countries of the world according to the following parameters: area, efficiency, environmental load on the territory of the country, number, density, forecast of population growth or decline for 2050, main agricultural land (arable land, pastures, the provision of the population, degradation and pollution of the soils), forest resources (including security per capita, share in the area of countries), fresh water resources (including per capita provision and availability), greenhouse gas emissions, including per capita, the proportion of mammals endangered, proportion of areas of preserved ecosystems. The data obtained was displayed on the maps; a common legend is built for them in tabular form. A number of other parameters of the state of territorial resources and the environment were also studied. In the process of research, the most important cities of these countries were also studied and diagrams showing their similarities and differences in a number of indicators were constructed: area, population and population density, time of foundation, climatic and landscape parameters, the presence of UNESCO World Heritage Sites, high-rise construction parameters. The developed methodology is effective for assessing a variety of data on territorial resources that can be used to build models of sustainable development of the largest countries and regions of the Earth.

Abstract A year ago, in Ostrava, one of the major RDI (Research and Development for Innovation) projects was initiated in the Moravian-Silesian Region, called the Institute of Clean Technologies for Mining and Utilization of Raw Materials for Energy Use. During the first year, many of the top and often unique research laboratories and workplaces were built with a budget of over CZK200m, such as “Workplace of Electron Microprobe”, „Workplace of Tomographic Methods“, “Workplace of Hydrochemistry and Hydrobiology”, “Workplace of Thermal, Hydraulic and Mechanical (THM) Processes in Rocks”, “Workplace of Water Jet”, “Isotope and GCTOF Laboratory” and many others. This laid the basis for various research programmes with truly extraordinary extent and impact not only on the Czech industry but also economy of other EU member states.
