Assessing state of water protection zones of Volga River within Ilyinka village area (Astrakhan region)

Anthropogenic pollution of water basins may become a serious threat for ecosystems and human health. Pollutants are transferred through food chains or directly when untreated water is used, released to soil through subsoil waters or during floods. The increased anthropogenic load on rivers’ hydrosystems, especially in their del-tas, is becoming rampant these days. The goal of the research is to study the coastal areas and to assess the state of vegetation. To achieve this goal, standard methods of biotesting and bioindication were applied in the territories of two water-protection zones – those of the Volga River and the Nozhovskiy erik (shallow channel in the Volga delta – translator’s note) near the Ilyinka village. The water quality in the Volga River, within the examined range, is stably characterized as “dirty” (4th class). The exceeded level of maximum permissible concentrations for petroleum products, heavy metals (mercury, zinc, molybdenum), sulfides and phenols is observed. The research has not revealed the impact of the quality of water on phytotoxicity of the soil and indices of abundance of the vegetation that grows in this territory. Toxicity of soils is weak in the area of the Nozhovskiy erik, it is very weak in the area of the Volga River: the germination capacity of the test object (watercress) ranges between 67 and 88%, morpho-metric indices of plants do not differ much from those in control groups. Within the summer period the monitoring sites were characterized by the maximum frequency-abundance indices of typical representatives of the local flora, which are camel thorn (Alhagi pseudalhagi) and greater burdock (Arctium lappa). Vegetation in these areas is abundant, its state is assessed as satisfactory.

Change in the agrochemical properties of soils and the productivity of the wheel under the influence of electromagnetic waves

In recent years, in the world, the anthropogenic impact on the soil, entailing various changes in its properties, is becoming more severe. Especially it is necessary to note the lands located on the boundaries of the protection zones of linear objects. This article studies the agrochemistry of soils that are under zones and linear protection objects and the effect of electric waves on wheat productivity. Overhead power lines have a negative impact on the environment, in particular on its ecological, social, and economic systems due to the high intensity of the electromagnetic field around the lead wires. High-voltage power lines do not significantly affect the content of humus and nutrients.

Vulnerability mapping of karst springs and its application for the delineation of protection zones (Mecsek Karst, Hungary)

Over the past decade or two, vulnerability mapping become a useful tool to determine the sensitivity of karst aquifers and allows the analysis of karstic aquifers affected by human activities. The Tettye Catchment, one of the eight catchments of the Mecsek Karst aquifer (SW Hungary), supplies drinking water for Pécs, the fifth most populous city in Hungary. However, due to its partly urbanized character and heterogeneous karstic features, this catchment is highly sensitive to anthropogenic impacts. In this study we aimed to generate resource vulnerability maps and risk maps to assess the role of physical and anthropogenic factors on groundwater vulnerability in the Mecsek Karst. Two formerly validated methods were used, the COP (Concentration, Overlaying layers and Precipitation) and SA (Slovene Approach) methods. The resource vulnerability maps, validated by former tracer tests, were combined with the hazard map obtained from the COST action 620 and EU Water Directive to generate risk maps. Tracer-based transit times were commonly less than 20 days in the majority of the areas of extreme vulnerability. During the current study, a new protocol has been elaborated for the delineation of the protection zones of karstic aquifers. Comparing the two methods, the SA performed better in terms of intrinsic vulnerability mapping, as it had a higher spatial resolution and was more detailed than the COP map and had a more sophisticated vulnerability indexing. In addition, high spatial correlation was revealed between the transit time maps and the SA map. Reassessed risk zonation, with appropriate legal consequences, likely minimizes undesired human activities within the zone of protection, hence maintaining water quality that complies with the protection acts

Basic criteria for the formation of use-restricted zones in general system of territorial planning

One of the areas of land management in territorial formations is the establishment of a special legal regime for their use. The main purpose of this research is precisely the comprehensive analysis of legal and social environment in order to create special-condition zones for the use of territories. Deductive, inductive, analytical, comparative legal and other scientific methods have been applied. This article identified a diversified nature that regulates the process of establishing zones under consideration and, besides, specifics of their parameters and restrictions to be imposed. The documentation setting out such parameters for each zone to be established was examined, and the interrelation between the features of the objects and the configuration of their protection zones was established. The greatest emphasis was placed on differentiating the conditions for the formation zones in two ways: in the process of integrated development of territories and in the creation of conditions for the protection of those sites that are already in use. As a result, it was revealed how the establishment of special-condition zones for the use of territories influences the content of urban planning documentation. In the first case, such a procedure is carried out during the planning phase of allocation of engineering and transport infrastructure. In the second case, zoning is carried out in order to bring the legal regime of previously commissioned infrastructure elements or natural and historical-cultural sites into compliance with current legal norms. However, in both cases there is an inextricable link to the territorial planning system.

ANALYSIS OF CHANGES IN THE TECHNOLOGICAL PROCESS OF DEVELOPMENT AND COMPONENTS OF THE LAND MANAGEMENT PROJECT REGARDING THE ALLOCATION OF THE LAND PLOT

The article is devoted to the study of changes that have occurred during the development of the land management project for the allocation of land when changing regulations in the field of land management and cadastre. Land management projects for the allocation of land plots are developed in the case of the formation of new land plots from state and communal lands and in the event of a change in the purpose of land plots. They can also provide for the division, consolidation of land owned by one person. The main documents regulating the technological process of land management project development for land allotment are the Land Code and the Law of Ukraine "On Land Management", which consists of 6 stages: obtaining a project development permit, concluding an agreement with the developer of land management documentation, project development, project approval, entering data into the State Land Cadastre and project approval. Identified changes in the technological process of development of land management project for the allocation of land, which include: 1. The powers of local governments and executive authorities to transfer land ownership have been changed. At the same time, powers were tied to the boundaries of territorial communities instead of the boundaries of settlements. 2. Simplified the procedure for cadastral survey of land. The procedure of agreeing on the boundaries of the land plot and restrictions, transferring the boundaries in kind (on the ground) and establishing boundary markers becomes optional. 3. The state examination of land management documentation was canceled. 4. Simplified the procedure for approving the land management project for the allocation of land. The agreement with the territorial body of the State Geocadastre on the location of the land plot and the bodies implementing the state policy in the field of cultural heritage protection, forestry, water management, environmental protection, urban planning and architecture has been canceled. The following is added to the cadastral plan of the land plot: information on the transfer in kind (on the ground) of the boundaries of protection zones, coastal protection strips and beach zones, sanitary protection zones, sanitary protection zones and zones of special land use regime and land boundaries; information on the established boundary markers.

Modeling the Size of Protection Zones of Cultural Heritage Sites Based on Factors of the Historical and Cultural Assessment of Lands

This article addresses the global issue of preserving cultural heritage, which is associated, among other things, with the lack of provision for boundaries of protection zones for cultural heritage sites. This paper analyzes the worldwide experience in the field of establishing protection zones for cultural heritage sites, identifies the issues of preserving cultural heritage in Russia, as well as imperfections in the management of lands containing cultural heritage sites. To improve the management of such lands, a method of historical and cultural assessment of territories has been developed, which, on the basis of evaluative factors, makes it possible to characterize the historical and cultural value of a territory. In this article, based on this list of factors, a method for mathematical substantiation of the boundaries of protection zones of cultural heritage sites has been developed; this method includes seven stages. Using mathematical and statistical methods, models were obtained to determine the area of the protection (buffer) zone and the development control zone, the analysis of which revealed differentiation between the factors of historical and cultural assessment that characterize the urban environment, depending on the type of zones. The interpretation of the obtained models and the fields of their use are given.

Risk Assessment of Water Intakes in South-Eastern Poland in Relation to the WHO Requirements for Water Safety Plans

Since 2017, risk assessments for water intakes in Poland have provided the basis for decisions to establish indirect water protection zones. The preventive, risk-based approach and the related risk minimization measures are required under the provisions of the Drinking Water Directive (DWD) of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption. This approach is in line with the World Health Organization (WHO) recommendations for water safety plans. The aim of this study was to present a methodology and to carry out a risk assessment of the threats to surface water intakes, which in Poland, should be completed by the end of 2022. Risk assessments were performed for four onshore-type surface water intakes located in south-eastern Poland. The results were presented in aggregate form, which enabled clear presentation and conclusions. It was found that the greatest risks are associated with seasonal changes in water quality (mainly high turbidity and water blooms), unregulated sewage management, the occurrence of floodwater flows and catastrophic events caused by the potential failure of wastewater treatment plants. Based on the results of the risk assessment, the need to establish new, or to adjust the existing, protection zones for the analyzed water intakes was identified.

THE CONCEPT OF THE SANITARY PROTECTION ZONE: APPROACHES AND DEFINITIONS

The article gives an authorial definition of the sanitary protection zone. Sources of ionizing radiation were not taken into account when the definition was created as they have their own specifics and require individual investigation. The definition of the sanitary protection zone is given through the substance of its features, which are disclosed through analysis and comparison of regulatory acts, draft regulatory acts and literature. The features of the sanitary protection zone are the following: facility in respect of which the sanitary protection zone is established; the purpose of its establishment; zone size and boundaries; zone location and configuration; restriction of rights within the zone boundaries. It is proposed to define the facility in a general term “real estate”. It is defined that the purpose of establishing a sanitary protection zone is to ensure the absence of harmful impact on human health outside its boundaries. The size of a sanitary protection zone is calculated in eight cardinal directions taking into account the chemical, biological and physical impact on atmospheric air. The location of a sanitary protection zone is determined around an industrial facility and resembles a belt in configuration. The boundaries of a sanitary protection zone are determined by the geodetic method. The size and boundaries of a zone are shown in urban development zoning maps and in the public cadastral map. Restrictions within sanitary protection zones are expressed in prohibition on construction and obligations on compliance with the established regime.
