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.
Afficher plus [+] Moins [-]The current state, problems and prospects of the use of land resources of Ukraine in conditions of war
2024
Bavrovska, Nataliia
The pre-war state of land resources in most of Ukraine was characterized as strained, and sometimes critical, with a tendency to deteriorate, which significantly complicated the socio-economic development of Ukraine and its regions and negatively affected the landscape and biological diversity, health and living conditions of the population. The article examines topical issues of problems and prospects for the use of land resources of Ukraine in the conditions of martial law and post-war reconstruction. As a result of Russia’s military aggression, Ukraine faced mass shelling, missile strikes, radiation contamination, air pollution, littering of territories, unburied or chaotically buried bodies of the dead, mining and other challenges. This has led to aggravation of economic, environmental and social challenges of food supply both in Ukraine and in the world. In connection with military actions, the land resources of Ukraine are subjected to large-scale destruction, deterioration of the soil quality, degradation processes are intensified, land resources are damaged, owners and land users suffer material losses. Agricultural lands suffered two significant types of damage – mine contamination, both on the frontline and in occupied (or formerly occupied) territories, and direct physical damage, from contamination by mines and unexploded ordnance. As of March 20, 2022, the area of damaged soil cover was 6,582.0 hectares, out of 1,655,845.3 hectares of surveyed arable land. For rational use and protection of land, restoration of soils and improvement of their fertility, preservation of productive, ecological and social functions of soil cover, the following important measures should be implemented: actualization of scientific research on the restoration of degraded soils, in particular in the direction of studying the impact of armed aggression of the Russian Federation on the soil cover of Ukraine; determination of the current state of soil health; improvement of the methodology for determining the amount of damage and losses to land and soil resources caused by armed aggression; development and pilot implementation of rehabilitation technologies for war-damaged soils.

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.

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.
Afficher plus [+] Moins [-]Prevention of land degradation processes
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).

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.

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.

2019
Khasaev, G., Samara State Univ. of Economics (Russian Federation) | Vasilieva, D., Samara State Univ. of Economics (Russian Federation) | Vlasov, A., Samara State Univ. of Economics (Russian Federation) | Parsova, V., Latvia Univ. of Life Sciences and Technologies, Jelgava (Latvia)
The issues of environmental protection, prevention of degradation and reclamation of damaged land are currently very significant and relevant. As damaged land has been observed the land where low productivity and low economic potential have arisen and natural productivity of ecosystems is changed due to human-caused activities. The nature and extent of the violation depends on the type, depth and duration of anthropogenic impact, on adopted system of work organization and the conditions of the environment. Black soil dominates in the soil cover in Samara region; therefore there has been developed agricultural production. However there are located large oilfields and gas fields, which are under active exploitation and reduction of vegetation, dumping technological sites, laying trenches for pipelines, etc. have been noticed, which leads to formation of technogenic soils, damaged land cover, loss of soil fertility and land use type change. There special restoration measure − reclamation should be putted into practice on the territory of all categories of land, but especially on agricultural land. The aim of the article is to study the situation with damaged agricultural land in Samara region of Russia and to develop scientifically based proposals for regeneration of its fertility after reclamation measures. The problems of pollution of agricultural land in the region have been investigated, main sources and types of pollution have been analysed, as well as legal, methodological and environmental protection documents on land reclamation have been studied. The peculiarities of reclamation of land on federal, municipal and property level have been considered. The article presents measures for reclamation of the land on the example of natural monopolies in the territory of the Samara region.

2018
Golej, J., Slovak Univ. of Technology in Bratislava (Slovak Republic) | Panik, M., Slovak Univ. of Technology in Bratislava (Slovak Republic)
The issue of brownfields and their analysis in Slovakia have not been given such emphasis over the last decade as in the neighbouring EU countries, such as in Austria or in the Czech Republic. The situation is completely different in Bratislava and also in the rest of Slovakia and the development of this type of area is almost unrealized. A frequent argument is problematic ownership relationships to the unused, degraded land. However, the real problem is the higher financial costs associated with brownfields regeneration. Despite this fact, brownfields can be considered as an area with relatively large development potential within the urbanized area and one form of hidden reserves of both, local and national economy. Among the indisputable benefits of using brownfields, we can include reduction of the extensive land use of agricultural land for rural area. In the long run, Bratislava is preparing a search study of neglected and unused land within the capital. It is due to be completed in the course of 2018, and will be an important basis for a new territorial plan and the development of Bratislava. In the following article, we analyse brownfield land in Bratislava. The already realized brownfield projects are also mentioned, while we are trying to point out their main advantages and disadvantages.
