Land management against land/real estate degradation
2014
Pomelov, A., Belarussian Research Inst. on Land Management, Geodesy and Cartography, Minsk (Belarus)
The article concentrates on problems of land/real estate degradation in Belarus, as well as on the ways of solving them by means of land management. The analysis of various documents resulted in the conclusion that there is a lack of a unified conceptual and terminological framework with regard to the following terms and concepts: ''degradation'', ''land degradation'', ''degraded lands'', ''land conservation/protection'', ''real estate degradation'' and others. The concepts of ''land parcel'' and ''real estate unit'' are compared. As an effective tool for combating degradation of land and real estate the article offers more efficient use of land management system developed for this purpose, as well as other legislative, institutional, organizational and technological measures.

2023
Suska, Anastasiia | Shevchenko, Serhii | Valčiukiene, Jolanta | Jukneliene, Daiva | Opashniuk, Anna
In Ukraine, intensive agricultural use involves a significant area of land with degraded and unproductive soils, which is economically impractical and ecologically dangerous. Part of the land was impacted by military activities. One of the tasks of sustainable development in Ukraine is to stop the process of land degradation, achieve a neutral level of land cover degradation, and promote the restoration of their productivity. This can be achieved by growing energy crops on degraded soils. Energy crops can grow on infertile soils and accumulate a significant amount of biomass, which is an important argument in favour of the development of green energy. The purpose of this study is to determine the specifics of planning work on the phytoremediation of degraded lands when using energy plants and the subsequent production of fuel pellets and briquettes. The focus is on measures to comply with the requirements for the content of pollutants in solid biofuels, which will be made from energetic plants used in the process of phytoremediation of degraded soils. The ratio of pollutant concentrations in soil and plants to their maximum permissible concentration in biofuel is proposed to be used at phytoremediation planning. This study substantiates recommendations for planning the phytoremediation of soils impacted by military activities using energy plants. These recommendations, in particular, concern: the choice of plant species; estimates of the duration of the phytoremediation process; application of precision farming methods in phytoremediation of lands; use of stochastic models of the phytoremediation process.

2022
Zhyrgalova, Alima | Zhildikbayeva, Aizhan
The purpose of the article is to consider the features of the anthropogenic impact on agricultural land in the Republic of Kazakhstan (RK). The article deals with the current problem of agricultural land degradation, and desertification in Kazakhstan, where one of the causes is the anthropogenic activities of the population and the aridity of the country's climate. Most of the territory of Kazakhstan is located in conditions highly vulnerable to anthropogenic desertification when in combination with natural factors of desertification the ecological situation is sharply deteriorating. Another cause of land degradation is urbanization and intensive degradation of desert habitats — unsystematic road network, regulation of river flows, illegal cutting of saxaul for firewood for sale. As a result of urbanization and intensive agricultural development of the foothill strip in the south and east of the country, the natural vegetation cover is highly disturbed. Roads, pipelines, and power lines, which are being laid at an increasing rate, have a great impact on the fauna. The area of land occupied by mining enterprises is steadily growing. In the last 10 years, the areas of oil and gas extraction, development of uranium ores, etc. in Western Kazakhstan, the Eastern Caspian Sea region, the Betpakdala desert, etc. have been sharply increasing. As a result of insufficiently thought-out land management from water erosion 5.6 million hectares of arable land was affected and grain yield was reduced by 20–30%. Degradation of agricultural lands, including pastures, is 30–50% and higher % in 9 of 14 regions of Kazakhstan. The use of the existing model of agricultural development of raw materials leads to inefficient economic development and constantly increasing pressure on ecosystems. The soil in Kazakhstan is very vulnerable, as it is comprehensively affected by various anthropogenic factors that lead to the constant deterioration of its quality. Soils near the Aral Sea and the Caspian Sea are subjected to the most intensive degradation, as wind erosion is widespread there.

2016
Stoiko, N., Lviv National Agrarian Univ. (Ukraine) | Tkachuk, L., Lviv National Agrarian Univ. (Ukraine)
In Ukraine, degradation of land resources is a complex ecological problem, preventing sustainable development of land employment. Land protection from degradation requires development of measures in the process of land management at regional and local levels. Efficiency of the measures depends considerably on reliable information about quantitative and qualitative conditions of lands, due to the fact that it forces timeliness of the research. The aim of the research is to study problems of land degradation in terms of land management while developing measures of land resource protection. To reach this aim, the following tasks were set out: to analyse the drawbacks of informational support in terms of land management fulfilment at the current stage of land relations development; to describe prospective ways to implement the measures on land protection from degradation in Ukraine. Methodological basis of the research is includes the method of system analysis (performed while studying the process of land resource degradation) and cartographic method (employed while detecting the spread of degradation processes and its drawbacks in land employment). The research has determined that soil maps and plans of employment of lands do not provide reliable information about quantitative and quantitative conditions of land resources. The existing organisation of land use, first arable one, does not always correspond to soil-conserving requirements. It is proposed: to update plan-cartographic material based on space images and data of agrochemical classification of agricultural lands; to establish efficient organisational and economic mechanisms to implement ecological policy in the field of land management.

2015
Parsova, V., Latvia Univ. of Agriculture, Jelgava (Latvia) | Cahrausa, I., Ministry of Environmental Protection and Regional Development, Riga (Latvia)
Land degradation is a topical issue not only in Latvia, but also in Europe. Even the real estate additional tax rate of 1.5% does not prevent agricultural land from overgrowing, and there is no other legal mechanism to control it. One of the mechanisms of prevention of land degradation process is reconstruction of drainage systems, change of worthless agricultural land (less than 25 points) to forest land or improvement and return of agricultural land (more than 25 points) to economic production. Although such actions require financial resources, there may be a variety of financial support programs, for example, the decrease of the real property tax rate (in case of afforestation).

2015
Stoiko, N., Lviv National Agrarian Univ. (Ukraine) | Perun, N., Lviv National Agrarian Univ. (Ukraine)
Solution of ecological problems is an urgent and extremely important task at the present stage of social economic development of Ukraine. Unreasonably high degree of economic (mostly agricultural) reclaiming of area causes spreading and intensification of degradation processes in ecosystems. Conservation of lands, including the one carried out by means of foresting of degraded lands, is the principal way to renature environment. The article concerns an issue of land conservation in the context of ecosystem services of forests. The aim of the article is to assess the economic value of ecosystem services of forests in case of land conservation. To achieve the aim the authors developed a classification system of ecosystem services of forests according to their functional purposes; provide the calculation of prospective economic value of ecosystem services while foresting of a land plot with heavy eroded soil. The research was carried out using system, monographic and abstract-logical methods. The integral evaluation of prospective ecosystem services of forest in case of foresting of degraded land resulted in: minimum – 5. 07 thousand UAH per 1 ha in a year, maximum – 35. 91 thousand UAH per 1 ha in a year. The calculation of economic costs of ecosystem services should be applied for assessment of the economic value from protection of nature-protective areas as well as implementation of economic stimulation for land conservation.

Stoiko. N, Lviv National Agrarian Univ. (Ukraine) | Kostyshin, A., Lviv National Agrarian Univ. (Ukraine) | Kryshenyk, N., Law and Engineering Company “Roksalˮ, LLC, Boryslav, Lviv Oblast (Ukraine)
Loss of the territory biological diversity is one of the most serious challenges for sustainable development of Ukraine. Solution of that problem is the essential constituent of the national ecological policy, which is focused on introduction of the ecosystem approach in all spheres of social and economic development, including protection of biological diversity. The goal of the article is to study some aspects of protection of the biological diversity of rural areas by means of ecosystem renaturalization by transforming degraded and marginal arable lands into forests, grassland and wetlands. The research proposes an organizational mechanism of increase and expansion of the territories with natural lands, which includes planning of land use, landscape and ecological zoning, territorial organization, evaluation of ecosystem benefits, land users’ motivation. The researchers stress on the necessity to create ecological networks and agroforestry. Such structural organization of rural area supports a balanced combination of the “human-land-ecosystem” system due to protecting the main ecosystem functions, i.e., provision of regulating and habitat services. While determining the directions of use of the land plots with degraded and marginal arable lands, the obligatory condition is to justify the benefits from those ecosystem services. To regulate the environmental land relations, it is recommended to introduce conservation easement.

Khasaev, G., Samara State Univ. of Economics (Russian Federation) | Vlasov, A., Samara State Univ. of Economics (Russian Federation) | Vasilieva, D., Samara State Univ. of Economics (Russian Federation) | Parsova, V., Latvia Univ. of Life Sciences and Technologies, Jelgava (Latvia)
The article discusses the current state of forest land, the history of formation of large tracts of forest in the Samara region and analyses some of the results of implementation of target programs to improve the forest cover in the region under the Kyoto Protocol. This program was designed for the period from 2006 to 2015, but in 2009 was discontinued. However, large segment of assets was allocated and a number of works was carried out. Currently the objectives of the programme to increase the forest cover in the territory of Samara region through the creation of tracts of forest are not achieved. Tree and shrub plantations play an important role in reducing the activity of processes of erosion, prevent degradation and desertification. Therefore, the problem of increasing forest cover, especially in the steppe zone of the region, to the level of the preindustrial era remains relevant and requires science-based measures for their solution.

The research studies the issue of ecological stability of rural territories that is the most important component of the national environmental policy of Ukraine. A special attention is paid to degradation of arable lands as the main ecological problem of land management. On the example of Lviv region, the authors calculated the index of ecological nonconformity of current use of arable lands, proving a considerable excess of permissible ploughing of lands in the region. The carried analysis confirms that no measures were performed concerning land protection, including conservation that in the recent years. In this context it is necessary to improve land resources management on the basis of sustainable development. Integration is considered to be the main principle of land resources management. The research proves that solution of ecological problems of land management requires achievement of a set of coordinated targets concerning development of rural territories, land resources management and national environmental policy based on the principles of suitable development. The targets include: planning of land use outside settled areas on the landscape and ecological basis; land inventory; formation of the land bank of agricultural lands; development and support of alternative kinds of activity on rural area; development of an efficient mechanism to encourage performance of land protection measures; improvement of environmental responsibility of population and development of ecological education. The methodological basis of the research is the concept of sustainable development, which expects support for a continuous character of development in order to meet the current needs along with ensuring the needs of future generations. The fulfilment of the task requires examination of scientific works on the issue of sustainable management of land resources and an ecological component of rural territory development.

With growing importance of the global economy, one of the basic natural resources − intensity of land use − is also increasing, which often is the cause of land degradation processes. The causes and manifestations of brownfields are diverse, and their elimination is the first prerequisite for the sustainable use of land resources and development of each region. Improvement, maximal and efficient engagement in economic activity of brownfields is one of the key challenges for sustainable resource use that makes significant contribution to regional development. The reuse of brownfields has significant impact on sustainable development as it meets all three of its objectives: improving the economy, improving social cohesion and the environment. The aim of the article is on the basis of special literature examples to examine issues of sustainable development, evaluation and restoration of brownfields, transformation of brownfields into recreational areas, as well as further use of brownfields in cities and rural areas.
