The aim of the study is to develop a project for the rational organization of the use of agricultural land for land use on the basis of a comprehensive integrated assessment and landscape-ecological analysis, involving their landscape-ecological optimization, conservation of landscape diversity. This project will establish the main criteria for the optimization of agricultural lands as natural-economic systems: land and resource security; level of forest cover; agricultural load on landscapes (erosion level, specific gravity of irrigated and drained lands, livestock load per 100 ha of fodder land); the degree of agrogenic load on agrolandscapes (specific gravity of steam, indicators of plowing and agricultural development); landscape-ecological conditions (landscape situation, drainage of landscapes, relief, soil; water and radiation balances; manifestation of adverse physical and geographical processes); spatial and technological conditions (a variety of landscape patterns of arable land and other lands, their configuration and size); the degree of environmental tension (the degree of development of natural physical and geographical processes and anthropogenic ones: salinization, waterlogging, flooding, pollution of soils, snow, air and water basins, etc.); the amount of agricultural losses; environmental, social and economic efficiency of the implementation of design developments. The methods used are: abstract-logical, integrated landscape and environmental assessment, cartographic, modeling methods.

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.

The article considers the current state of use of land resources of the Central Forest-Steppe of Ukraine in the context of administrative regions – Vinnytsa, Kyiv, Kirovograd, Poltava, Cherkasy. Structural distribution of land resources by types of land was analyzed. The Central Forest-Steppe of Ukraine as of 01.01.2016 is 12890,9 thousand hectares. A significant part was occupied by agricultural land – 9321,8 thousand hectares (72,3 %), forests and forest cover areas – 1842,63 thousand hectares (14,3 %), built-up land – 538,4 thousand hectares (4.2 %), water (territories covered with surface water) – 579,5 thousand hectares (4,5 %), other lands – 455,22 thousand hectares. Features of structural distribution were investigated of agricultural land. The excessive level of agricultural development of the territory is determined – 72,3 %, the area’s cultivation is 61,2 %, agricultural land plots – 84,6 %. Such indicators significantly exceed the maximum permissible levels, which indicate extensive use of land. It is established that the structure of land is ecologically unbalanced. The period of 2005–2016 was analyzed a dynamics of land fund changes. Thus, the area of land has undergone some changes, but they are completely unimportant and do not radically change. The reduction of agricultural land is extremely low (0,8 %), the increase in the forest area as an ecolabelling lands is only 0,2 %. The decrease in the share of arable land in the total area of agricultural land is very small – 4,0 thousand hectares (0,03 %). The reduction of arable land was observed in Kyiv region – by 13,7 thousand hectares, in Vinnyts’a – by 4,4 thousand hectares, Cherkasy region – by 1,8 thousand hectares. There is a slight increase in the area of arable land in Kirovograd region – by 1,4 thousand hectares and in Poltava region – by 14,5 thousand hectares. We offered measures to optimize the use of land resources. In particular, an important task in the field of optimization of the structure of the land fund should be measures for the removal of intensive cultivation of degraded, low productive land.

The current state of land use in Ukraine is characterized by high agricultural development and land cultivation. The predominant share in the total land stock of Ukraine is occupied by agricultural land (70.8% of the country's territory). Ukraine accounts for about 0.45% of the world land fund, while arable land occupies 2.4% of its world-wide area. According to resource-based indicators of land use Ukraine is also characterized by an extremely high level of development of living space and only about 8% of the territory can be attributed to anthropogenically unchanged. Ecological and economic aspects of land use include of rational land use, which characterizes the optimal involvement of all lands in economic circulation and their effective use for the main purpose, creation of favorable conditions for increasing productivity of agricultural land and obtaining from the unit of area the maximum amount of products at the lowest cost of labor and funds. The article substantiates that degradation of soils has its own characteristics, caused by various factors and processes. It is established that the practice of land use and the state of study of the above problems will require further study of the preconditions for the development of land degradation processes caused by the main factors: human economic activity and climatic and relief-ground conditions. The existing system of land protection in agriculture due to the influence of a number of natural and economic factors, as well as insufficient attention from the state does not ensure their rational use. Therefore, it is necessary to adhere to an integrated system of protection of agricultural land.

Abstract The majority of forest cover in the British Uplands had been lost by the beginning of the Nineteenth Century, because of felling followed by overgrazing by sheep and deer. The situation remained unchanged until a government policy of afforestation, mainly by exotic conifers, after the First World War up to the present day. This paper analyses the distribution of these predominantly coniferous plantations, and shows how they occupy specific parts of upland landscapes in different zones throughout Britain Whilst some landscapes are dominated by these new forests, elsewhere the blocks of trees are more localised. Although these forests virtually eliminate native ground vegetation, except in rides and unplanted land, the major negative impacts are at the landscape level. For example, drainage systems are altered and ancient cultural landscape patterns are destroyed. These impacts are summarised and possible ways of amelioration are discussed. By contrast, in recent years, a series of projects have been set up to restore native forest cover, as opposed to the extensive plantations of exotic species. Accordingly, the paper then provides three examples of such initiatives designed to restore native forests to otherwise bare landscapes, as well as setting them into a policy context. Whilst such projects cover a limited proportion of the British Uplands they nevertheless restore forest to landscapes at a local level.

This paper analyzes agricultural land and structural changes in plant production Montenegro. The Montenegro represents a significant potential for agricultural development, but plant production insufficiently developed in relation to natural resources and the demands of intensive agricultural production. Average possession by agricultural holdings in 1960 amounts is 5.34 ha with only 2.05 ha arable area per agricultural holdings. Yet more unfavorable is the situation with arable surfaces. Namely, agricultural holdings in the Montenegro in 1960 are on average dispose with maximum of 0.74 ha of arable land. Judging by the size of the cultivated area, production volume, as well as according other parameters, plant production in the Montenegro in 2007, mainly used for meeting need households. A smaller area for is market. The role of the Montenegrin village and agriculture must be first-rate, as are its potentials, the main power future development of Montenegro. This requires radically new relationship between society and science to agriculture and the countryside. Instead of the existing approach in which they observed the preventive as producers of cheap food has to be developed a new concept, a comprehensive agricultural and rural development, which will be based on demographic, natural, economic and socio-cultural potential of Montenegro.

This article focuses on afforestation of agricultural land and reviews agricultural land afforestation changes in Poland implemented by beneficiaries (natural or legal persons) of the RDP, with special regard to regional differences. Furthermore, the study distinguished between trends in afforestation for separate EU budgetary periods: 2007-2013 and the current financing period 2014-2020. The study applies data published by the Central Statistical Office for 1995-2018, concerning the size of the forest cover by ownership type and spatial distribution, the forest area in the total land area of a farm, and the average price of arable land. Additionally, data concerning the afforestation of agricultural and non-agricultural land have been obtained from the Agency for the Restructuring and Modernisation of Agriculture for 2007-2018. Results show that the afforestation of privately-owned agricultural land was 33,053.53 ha in Poland between 2007-2013, whereas it was 6,742.06 ha between 2014-2018. In both periods, the largest land area was afforested in the Warmińsko-Mazurskie and Mazowieckie voivodships, while the smallest in the Śląskie and Małopolskie voivodships. Although the current financing period will expire in 2020, available data suggest that the total afforested area of agricultural land area in the current period will be smaller than in the previous period. The comparison of both afforestation periods shows that only in the case of the Warmińsko-Mazurskie and Opolskie voivodships, the average percentage share of forest cover in total land area owned by a farm slightly increased, but both voivodships, are of little significance in afforestation efforts. The most significant decrease in the newly afforested area was in the Małopolskie Voivodship, which is likely related to average farm size and land location as well as related natural conditions.

<p>With rising demand for food in Sub-Saharan Africa (SSA), cropland expansion represents the main strategy to boost agricultural production. However, cropland expansion is not a sustainable form of agricultural development as there is limited arable land and increasing soil degradation in SSA. Cropland expansion needs to be monitored in order to focus intervention and propose alternatives. In this study, we monitor agriculture expansion over the past decades across Malawi using Landsat satellite data and explore factors that can explain expansion using Malawi integrated household survey data. The preliminary results showed that cropland expansion has widely occurred across the country, and the newly expanded croplands have higher productivity compared to the croplands with long cultivation history. We also found that estate agricultural land contributes to 40% of the expanded area and the level of irrigation is negatively correlated to expansion, being the dominant factors that are associated with expansion in Malawi. The results will further help to offer localized information for policy making and to develop strategies for conserving land.</p><p> </p>

Abstract ContextThe vital challenge for the context-based landscape planning is integrating assessments of for both intrinsic properties of a unit and its value in a broad spatial context.ObjectivesThe purpose is to develop the procedure which provides context-based criteria at relevant scales, considers matter flows and dynamic events.MethodsThe methodology involves identification of landscape patterns, revealing mechanisms of radial and lateral relationships, considering changes of landscape patterns, and revealing functioning mechanisms causing directed changes. The proposals proceed from multiplicity of patterns and integrate knowledge of processes in biophysical units, catenas, basins, and matrix elements. The plan was elaborated for the taiga landscape in northern European Russia.ResultsDevelopment of ecological network is aimed at increase of forest cover in basins up to 35% to enhance runoff regulation, prevent soil erosion, and stabilize the riparian biocorridor. The highest significance was assigned to the units that have intrinsic ecological values and contribute to lateral transportation of matter over vast areas. Width of buffer strips intercepting input of pollutants to rivers was adapted to proportions of elements and neighborhoods in catenas. Outside the ecological network, we identified priorities for the multifunctional use of units based on the assessment of drainage conditions, soil quality, and risk of erosion. ConclusionsThe procedure takes into consideration landscape hierarchy and multiplicity of spatial patterns. Integrating multiple models is in compliance with the systemic essence of a landscape ensuring understanding of geodiversity, lateral connections, and the emergent effects that ensure the landscape services for society.

<p>Arable land availability for agricultural extensification is a determining factor to achieve Indonesia’s food self-sufficiency and to become the world food supplier in 2045. This study aimed to evaluate land reserves for future agricultural development. Spatial analysis was conducted using land cover map, peatland distribution map, indicative map of suspension of new permits, forest status map, licensing map, and agricultural land use recommendation map. The land assumed to be potentially available should be (i) idle land covered by shrub as well as bare land, (ii) agronomically suitable for agriculture, (iii) within the designated area of non-forest uses (APL), conversion production forest (HPK), or production forest (HP), (iv) outside the moratorium area, and (v) outside the licensed area. Analysis results show that out of 29.8 million hectares of idle land, only about 7.9 million hectares are potentially available for future agricultural extensification. The available potential land area is much less than that required to meet the self-sufficiency target and to become the world food storage by 2045, i.e. of 5.3 million hectares for rice crop, shallot and sugar cane, and about 10.3 million hectares for upland rice, maize, soybean, peanut, mungbean, sugar cane, shallot, cassava, and sweet potato. Therefore, the main strategies to take are intensification of existing agricultural land and a strict control of agricultural land conversion.</p><p> </p><p>Abstrak</p><p>Ketersediaan lahan untuk ekstensifikasi lahan pertanian menjadi salah satu faktor penentu keberhasilan untuk mempertahankan swasembada pangan dan untuk menjadikan Indonesia sebagai lumbung pangan dunia menjelang tahun 2045.

Hasil analisis menunjukkan bahwa dari sekitar 29,8 juta ha lahan telantar, hanya sekitar 7,9 juta ha yang berpotensi tersedia untuk ekstensifikasi pertanian masa depan. Luas lahan potensial tersedia ini jauh lebih rendah dari kebutuhan lahan untuk memenuhi target swasembada dan mewujudkan Indonesia sebagai lumbung pangan dunia menjelang 2045 yaitu 5,3 juta ha untuk padi sawah, bawang dan tebu dan sekitar 10,3 juta ha untuk padi gogo, jagung, kedelai, kacang hijau, kacang tanah, tebu, bawang merah, ubi jalar, ubi kayu. Oleh karena itu, strategi utama yang harus ditempuh adalah intensifikasi lahan pertanian eksisting dan pengendalian konversi lahan pertanian secara ketat.</p>

In the second half of the XIX century Western Ukrainian lands suitable for agricultural development could not provide their inhabitants with adequate well-being. Moreover, famine often prevailed in the region, and poverty raged. Ukrainians, who made up the majority of the rural population of the region, were particularly affected: almost 80% [7, p. 4]. Government statistics at the time tried to prove that all conditions were created for Western Ukrainian peasants to ensure their well-being. At the same time, for example, the following figures were used: peasants owned 62.2% of the land area, while large landowners, mostly Austrians, Poles, Germans, Jews and other peoples, only 37.8% of agricultural land. It would seem that Ukrainian peasant farms, which had the majority of arable land in their use, could prosper. However, the other side of this statistic was not mentioned: first of all, it was hidden that the best lands belonged to the owners of large farms. In addition, there were 3,734 communities in the areas used by the majority of peasants. Therefore, if we compare the size of the area of a large landowner and the average peasant economy, the peasant economy was 320 times smaller than the agricultural land of a large landowner. At the end of the 40s of the XIX century in almost all European countries the economic crisis deepened, mass strikes began. Governments became increasingly helpless, unable to control the situation. Political demands began to be put forward more and more often to the economic demands of the workers and peasants. The spirit of revolution hovered in the air. And soon it began. The revolutionary events that swept Europe in the spring of 1948 brought the peoples of Europe hope for a better future. The consequence of this revolutionary upsurge was the abolition of serfdom in the Austrian Empire, which also ruled Western Ukraine. First of all, the Ukrainian intelligentsia, which was based on priests, teachers, and lawyers, began active social and political work. However, the majority of the population still stayed away from politics: neither its general education nor their financial situation contributed to participation in the national movement. That is, the «Spring of Nations» still did not contribute to the «mass, widespread awakening of the national consciousness of the Ukrainian people of Galicia, Bukovina, Transcarpathia» [17, p. 15]. This required a lot of effort, first of all to inform the nation competently and politically about what educated people had to do [22].
