Purpose. To substantiate the features of the landscape-geographic model of the ecological passport of the lake basin for the needs of preserved and recreational nature management. The article is focused on the acute need in development of ecological passports of local environmentally protected sites for formation of a regional inventory of nature reserve fund. The concept of a natural aquatic complex (NAC) of the lake, a lake-basin system (LBS) served as a methodological basis of the proposed work. The research is based on the methods of field instrumental landscape-limnological searches with the use of laboratory diagnostics of soil samples of the catchment and bottom sediments of the lake, and the landscape-based analysis of the LBS. The results of the study are presented in the form of landscape models of NAC of Ozertse lake and the natural territorial complexes (NTC) of the catchment. Landscape complexes of the rank of a tract and aquatic facies are allocated in the OBS of Ozertse lake. The geochemical features of the bottom sediments of the water body on the example of one of the points of sounding, hydrological and morphologic-morphometric parameters of NAC of the lake and its catchment, and the landscape-metric characteristics of the integrated lake-basin system are analysed. Conclusions. The developed landscape-geographic model of the lake basin system will be a base for the ecological passport of Ozertse lake. Ecological passports of such type are needed for ecological, tourist-recreational, water management and land reclamation institutions and establishments, as well as for the newly formed united territorial communities.

Topicality. The available information on specific lakes of nature protection fund (NPF) objects, primarily of local significance, is limited to brief information on morphometric and hydrological characteristics, information on the rare component of aquatic organisms and the species diversity of the adjacent catchment areas. This state of affairs does not benefit the development of protected areas and encourages ecological and geographical searches of lakes or lake-basin systems, which are part of the NPF. Purpose is to assess the ecological and geographical condition of the lake basin system Strelske (hydrological monument of nature) for cadastral needs of NPF objects of Polissya region of Ukraine. Methods of regional constructive-geographical limnology, landscape-limnological analysis, soil-geochemical profiling of lake catchments, GIS-cartographic modeling. Results of the study are presented in the form of a cartographic model of the spatial-typological structure of the lands of the lake catchment. Shooting and substantiation of its geoecological condition, bathymetric map of the lake and morphological-morphometric and hydrological calculations of the LBS. The hydrochemical parameters of the lake were analyzed according to the block of indicators of salt composition, tropho-saprobiological characteristics and substances of toxic action. The lithological composition and capacity of the bottom sediments of the lake are estimated, the graphs of radial migration of chemical elements and compounds at one of the probing points are constructed and the qualitative composition of the lake sapropel is substantiated. Using GIS technologies, a landscape map of the natural-aqual complex of the lake was built. Shooting and landscape-metometric assessment of its morphological structure. Conclusions. The basin system has in the past undergone anthropogenic transformations as a result of reclamation nature management, which has limited the share of surface runoff into the lake. The lake water exceeded the MPC by 1.7 times the chemical oxygen demand, 1.6 times the biological oxygen demand and 2 times the total iron consumption. The lake basin is 65.7% filled with bottom sediments, which are represented mainly by organo-iron sapropel. The littoral aqua facies of the lake suffer the greatest anthropogenic load, which is connected with the recreational activities of the seasonally functioning recreation center.

The essence of the basin-landscape approach to the protection of the lakes of the national parks as an actual direction of research, which is formed at the junction of nature protection landscaping, hydrology and geoecology has been substantiated. The research algorithm, peculiarities of analysis and assessment of the status of the lake-basin system (LBS) have been found out, the factors that worsen the geo-ecological state in the lake and basin subsystems have been revealed, optimization measures in the objects of the nature reserve fund located within the natural reserve have been substantiated. The purpose of the study is to determine the parameters of the structure of lake-basin landscapes (on the example of Zasvitske lake, Nobel National Natural Park, Ukraine), liminary and landscape-metric indicators of the geo-ecological status of the LBS and the factors influencing it as an information and analytical basis for ensuring the protection and management of the LBS located in nature conservation area. The materials of the study were the long-term field landscape-limnological and geo-ecological studies of the authors within the Polesia region of Ukraine and, in particular, the LBS of the Nobel National Nature Park. The research methodology was based on complex physical-geographical methods, hydrological profiling and creation of bathymetric models of reservoirs, hydrochemical diagnostics of water masses of the lakes, geochemical analyses of bottom sediments, landscape mapping using GIS-technologies. The results of geo-ecological (landscape-ecological) researches of the lake-basin system of Zasvitske lake have been presented, in particular, original profiles and bathymetric model of the reservoir, landscape maps of the aqual complex and the lake catchment, limno- and landscape characteristics of the LBS have been shown. Considering the level of anthropogenic transformations of the LBS and the presence of a high proportion of ecologically-stabilizing lands (forests, reservoirs of natural origin), the level of sustainability of the LBS is estimated as high. An assessment of the hydrological characteristics of the reservoir and hydrochemical characteristics allows to attribute this lake to an oligotrophic type. The results of a comprehensive analysis of the geo-ecological parameters of the state of Zasvitske lake and its landscape-limnological functioning indicate the expediency of recreational specialization of nature management in the Nobel National Park, that includes this lake. Scientific novelty. The application of proposed landscape-basin approach and the algorithm of the LBS study increase the possibilities of functional zoning of national parks with high index of lakes, as well as solving the problems of nature protection and optimization of nature management. Practical importance. The created electronic landscape maps and the base of limnometric parameters can be used as reference documents for the certification and cadastral evaluation of the transboundary protected areas of Ramsar type, geo-ecological monitoring and an integrated management of lakes by the basin approach in conditions of intense climate change.

Purpose. To reveal the peculiarities of geo-ecological status of the lake-basin system (LBS) of Ozerianske lake for the needs of a balanced nature management. Methods.The research is based on methods of field instrumental landscape-geochemical searches using modern geoinformation technologies and laboratory-analytical diagnostics of soil, water and lake sediments. Results. The current state of economic development of the catchment of Ozerianske lake has been clarified. The results of the research of the hydrochemical composition of lake water have been presented. The results of the experiments with the determination of the content and features of radial, lateral migration of mobile forms of biogenic elements (N, P2O5, K2O) and heavy metals (Co, Pb, Cd, Cu, Zn, Mn) on a landscape soil geochemical microcatena within the catchment area of a lake have been analyzed. A slight excess of MPC in the content of Mn and Cd in the soils of the microcatena has been fixed. The feature of lateral migration of biogenic elements is the increase of their concentration from the eluvial to the superequal facies of the geochemical microcatena, and the radial feature is the decrease of their content with the depth of the soil profile. Moving forms of heavy metals (Co, Pb, Cd, Cu, Mn) are characterized by radial migration - increasing their content with the depth of the soil profile in the horizon (20-40 cm), and further towards the parent rock, their concentration mainly decreases. Conclusions. It was established that the catchment area of Ozerianske lake refers to the anthropogenic-natural (IV) type and has unsatisfying geo-ecological status. In order to improve the geo-ecological status of the catchment area, it is advisable to gradually increase the area of ecostabilizing lands (meadows, forests, forage areas); to control the application of mineral fertilizers and pesticide use, and to prohibit the plowing of land by a 50-100-meter coastal protective strip around the lake.

Current situation and agricultural management on the non-black earth area of Russia arebeing gradually worsen by the negative natural factors such as a significant increase of weather based climatic abnormal risks, deterioration of agro-meliorative conditions of agricultural lands because of colonization by tree and shrubbery vegetation and secondary bog formation, hidden degradation of soil fertility. When combined with functional loss of ameliorative complex and meliorative systems amortization, regional agriculture adaptation possibilities were rapidly limited. Production shortfall due no abnormal weather conditions for particular field crops was 19…48% during last five years, level of business realization of bioclimatic potential on a field was decreased by 7…12%.The complete realization of regional agricultural adaptive potential to weather based climatic changes and limitation of greenhouse gases emissions is possible on a basis of regeneration ofalll functions and aspects of ameliorative complex management. Toward this goal the coordinated actions of federal and regional management of Agricultural Complex, Scientific and Educational institutions, project foundations and managers are needed in a relation to human resources, scientific and regulatory supply. Any incomplete treatment in these fields inherent in visual negative consequences for food security and social economic development of rural areas of non-black earth zones not only at the current historical moment, but in a future also. Fundamental influence of solving of these problems deserves to scientific supply of innovative ameliorative complex, renewal of which should be based on principals of resources and energy preservation, nature management, computerization and digitalization management. During a long term research it was established that increase of average vegetation period temperature by lоСhas increased productivity of winter wheat, barley and summer wheat in average on 0,7 tons per ha, winter wheat and oat on 0,4 tons per ha, potatoes – 8,2 tons per ha, edible roots-6,4 tons per ha, cabbage 9,8 tons per ha, dry basis of herbage of multi and one age grasses–0,5 and 0,7 tons per ha. Increase of СО2 Concentration from 0,35 to 0,45% during last twenty years contributed into grow of yield in regional agriculture which can be estimated as 0,3 tons per ha per measure; searching remedy for agroclimatical risks decreasing production became drainage and irrigation systems (decrease 3…5 times);new method of reclamation of abandoned areas with transformation of biomass of tree and shrubbery vegetation into biochar makes it possible to decrease СО2 emissions up to times and get an adverse balance of СО2;secondary reclamation of lands covered by trees and shrubbery on area of 22ha used for vegetables and area of 37ha used for forage crops could supply a farmer with work and revenue sufficient for maintenance of one child what is on the major facts of population declaim in rural areas.

Рассмотрена проблема загрязнения Воронежского водохранилища в пределах Воронежской городской агломерации, в местах сброса вод с очистных сооружений предприятий левого берега. В работе использованы результаты количественного химического анализа донных отложений, выполненных на базе эколого-аналитической лаборатории факультета географии, геоэкологии и туризма Воронежского госуниверситета, а также данные мониторинга, предоставленных Федеральной службой по надзору в сфере природопользования и Департаментом природных ресурсов и экологии Воронежской области. База данных включает результаты наблюдений с 2000 по 2021 год. По составу осадков прослежена история аккумуляции загрязнителей, выделены проблемные зоны водоема в каждом исследуемом периоде. Выполнен пространственно-временной анализ содержаний загрязняющих веществ, рассчитаны «кларки концентрации» тяжелых металлов, по которым для каждой точки наблюдения в порядке возрастания значения признака построен ранжированный ряд. На основании лабораторных исследований и результатов их статистической обработки с применением корреляционного анализа сделаны выводы о перспективах существования и развития Воронежского водохранилища. Проверены корреляционные связи между «кларками концентрации» и суммой выпавших осадков за календарный и за гидрологический год. По содержаниям сероводорода в различные годы, сделаны выводы о диапазоне колебания концентраций и формировании цикличного процесса. Выделена зона устойчивой деградации водоема. Ее формирование происходит выше и ниже сброса с городских очистных сооружений левого берега города. Результаты многолетних наблюдений за качеством донных отложений указывают на значительную техногенную нагрузку со стороны Воронежской городской агломерации. Недостаточная очистка воды, медленная скорость течения и турбулентность природной воды ускоряет процесс естественного эвтрофирования водоема. The author considers the problem of pollution of the Voronezh water reservoir within the Voronezh urban agglomeration, in places of discharge of water from the treatment facilities of enterprises of the left bank. The paper uses the results of quantitative chemical analysis of bottom sediments performed on the basis of the ecological and analytical laboratory of the Faculty of Geography, Geoecology and Tourism of Voronezh State University, as well as monitoring data provided by the Federal Service for Supervision of Nature Management and the Department of Natural Resources and Ecology of the Voronezh Region. The database includes the results of monitoring from 2000 till 2021. On the basis of the composition of precipitation the author detected the history of accumulation of pollutants; as well she identified problem areas of the water reservoir in every study period. The author performed a spatio-temporal analysis of the contents of pollutants, calculated the "concentration clarkes" of heavy metals, according to which she created an ordered series for each observation point in ascending order of the attribute value. Based on laboratory studies and results of their statistical processing using correlation analysis the author draws some conclusions concerning the prospects for the Voronezh water reservoir existence and development. The correlations between the "concentration clarkes" and the amount of precipitation for the calendar and hydrological year have been verified. Based on the hydrogen sulfide content in different years, the author concludes about the range of concentration fluctuations and the formation of a cyclic process. She identified the zone of stable degradation of the water reservoir. Its formation occurs above and below the discharge from the municipal sewage treatment plants of the left bank of the city. The results of long-term observations of the quality of bottom sediments indicate a significant anthropogenic load on the part of the Voronezh urban agglomeration. Insufficient water purification, slow flow velocity and turbulence of natural water accelerate the process of natural eutrophication of the water reservoir.

The Impact

Abstract Compared to research on eutrophication in lakes, our understanding of eutrophication in rivers remains extremely limited. This is especially true of the impact of fires, which have become much more frequent in recent decades. Since the risks of eutrophication in rivers as a result of fires increase, it is important to timely assess the impact of fires on the state of rivers draining fire-prone territories. The aim of the study is to select and evaluate the reliability of criteria for impact of fires on eutrophication in stream on the example of the Simmi River (Bolon Nature Reserve, Far East, Russia). The tasks of the work are to assess the fire-prone of the territory from remote sensing data and and to identify markers of the impact of fires on the Simmi River. The fire-prone of the river watershed was estimated by the fire repeatability. The in situ study dealt with river bottom sediments. The sampling was carried out in in three month and the third year after the fire. To assess the impact of fires on eutrophication in the Simmi River, we used the P content in bottom sediments as a marker of the nutrient loading. The obtained results indicate high fire-prone and repeatability of fires the river watershed. In the first months after the fire, the response of the river system is the sequestration of P soluble compounds as a result of the binding of phosphate ions to vivianite. Vivianite is formed on the surface of clay microaggregates, which are removed by the stream over time. In three years after fire, vivianite-clay microaggregates were not detected. Flushing in flow system tends to reduce the scale of the fire impact.

Cet article se focalise sur la nécessité d'intégrer, de réconcilier les pratiques coutumières des peuples riverains (Pygmées et Lega) avec les pratiques de gestion moderne de conservation de la biodiversité afin de préserver et de protéger la Réserve Naturelle d'Itombwe (RNI, réserve de catégorie VI de l'UICN). Pour récolter les données sur le terrain dans les villages Lega et Pygmées proches de la RNI, trois techniques ont été utilisées (documentaire, focus group et entretiens semi-structurés). Les résultats obtenus nous ont permis de découvrir les modes de protection de la nature et les normes locales propices au développement durable dans la gestion et la conservation de la nature. Ils montrent qu'il est utile de prendre en compte les pratiques traditionnelles et les expériences vécues pour comprendre l'importance du monde vivant de ces deux peuples. Certaines plantes et certains animaux protégés par les Us et coutumes de deux peuples sont aussi des espèces protégées et interdites par la Convention sur le Commerce International des Espèces de Faune et de Flore Sauvages Menacées d'Extinction (CITES). Malheureusement, la forte croissance démographique, le christianisme, la modernité ainsi que la relation entre la pauvreté et la culture traditionnelle ont remis en cause ces pratiques culturelles et le nonrespect de coutume. Ces croyances, loin d’être stables et immobiles, sont souvent capables d’intégrer des formes de nouveauté et de s’adapter à des modalités variables. En dépit de ces obligations, les occasions s’offrent au niveau coutumier pour la bonne gestion de la nature. Il revient aux acteurs de la conservation tant nationale qu’internationale de s’approprier ces pratiques costumières pour une bonne gestion de la biodiversité. This paper focuses on the need to integrate and reconcile the customs and practices of the riparian peoples (Pygmies and Lega) with the practice of modern management and conservation of biodiversity in order to preserve and protect the Itombwe Nature Reserve (INR, which is an IUCN Category VI Reserve). To collect field data in Lega and Pygmy villages bordering the INR, three techniques was used (documentary, focus group and individual interviews). The studies uncovered ways of protecting nature and local sacredness that are conducive to sustainable development in nature management and conservation. They show us that it is useful to take into account traditional practices and lived experiences to understand the importance of the living world of these two peoples. In addition, some plants and animals protected by local knowledge are among the species protected and prohibited by the Convention on International Trade in Endangered Species (CITES). The strong demographic growth, Christianity, modernity as well as the grafting between poverty and traditional culture have challenged these cultural practices and the respect of customs. These beliefs, far from being stable and immobile, are often able to integrate forms of novelty and adapt to changing modalities. In spite of these obligations, opportunities exist at the customary level the good management of nature. It is up to national and international conservation actors to appropriate these customary practices for good biodiversity management.
