The article presents and describes the plants of the genus Rosa L. growing on the territory of the Dzungarian Alatau. As a result of the study of literature sources it was found that out of 57 species of the Rosaceae family growing in the territory of the CIS countries there are 10 species of the genus Rosa L. (R. beggeriana Schrenk, R. canina L., R. platyacantha Schrenk, R. laxa Retz., R. spinosissima L., R. alberti Regel, R.schrenkiana Crep., R. acicularis Lindl., R. majalis Herrm, R. nanothamnus Bouleng.). The state of the vegetation cover of the Dzungarian Alatau for 2015, 2017 and 2020 was also studied using the program. The gradual degradation of the plant community of this mountain system is determined.

The state of plant communities in areas located in the Tersko-Sulak lowland was studied by assessing phytocenotic indicators: the structure of vegetation cover, projective cover, species diversity, species abundance and elevated production, as well as automated decoding methods. There are almost no virgin soils and natural phytocenoses here; all of them have been transformed into agrocenoses (irrigated arable lands and hayfields, rice-trees and pastures). The long-term impact on pasture ecosystems of natural and anthropogenic factors leads to significant changes in the indigenous communities of this region. Phytocenoses are formed mainly by dry-steppe types of cereals with the participation of feather grass, forbs and ephemera, a semi-desert haloxerophytic shrub - Taurida wormwood. At the base of the grass stand is common coastal wormwood and Taurida wormwood - species resistant to anthropogenic influences. Anthropogenic impacts have led to a decrease in the number of species of feed-rich grain crops and a decrease in the overall productivity of pastures. Plant communities in all areas are littered with ruderal species. The seasonal dynamics of the land cover of the sites was estimated by the methods of automatic decoding of satellite images of the Landsat8 OLI series satellite for 2015, dated by the periods: spring - May 20, summer - July 23, autumn - October 20. Satellite imagery data obtained by Landsat satellite with a resolution in the multispectral image of 30 m per pixel, and in the panchromatic image - 10 m per pixel, which correspond to the requirements for satellite imagery to assess the dynamics of soil and vegetation cover. Lower resolution data, for example, NDVI MODIS, does not provide a reliable reflection of the state of soil and vegetation cover under arid conditions. In this regard, remote sensing data obtained from the Internet resource https://earthexplorer.usgs.gov/ was used.

The article considers the state of domestic production of fruit and berry products, their import and export. It is estimated that the production volumes of sugar confectionery products, including fruit and berry products, are almost continuously increasing. Marmalade accounts for a large share of the production of all fruit and berry products. Its share is 49.2%, including chewing marmalade with a share of 24.8%. Imports of these products are gradually decreasing. The assortment of imported fruit and berry products is dominated by ready-made confitures, jams, and fruit butter for retail trade (53%). Exports of these products are increasing from year to year, with exports to the CIS countries, China, and Mongolia dominating. Prospects for the development of the Russian market of fruit and berry products are formulated.

The possibilities of using remote sensing of the Earth data to assess the formation of phytocenoses at reclaimed dumps and landfills are presented. The objects of study are landfills and dumps in the Perm Territory, which differed from each other in the types and timing of reclamation work. The state of the vegetation cover on the reclaimed and self-overgrowing objects was compared with the reference plots with naturally formed herbage of zonal meadow vegetation. The process of reclamation of the territory of closed landfills was assessed by the presence and homogeneity of the vegetation layer and by the values of the vegetation index NDVI. To identify the dynamics of changes in the vegetation cover, we used multi-temporal satellite images from the open resources of Google Earth and images in the visible and infrared ranges of the Landsat-5/TM and Landsat-8/OLI satellites. It is shown that the data of remote sensing of the Earth, in particular the analysis of vegetation indices, can be used to assess the dynamics of overgrowing of territories of reclaimed waste disposal facilities, as well as an additional and cost-effective method for monitoring the restoration of previously disturbed territories.

This work intends to examine if there are associations between fish species and the state of conservation of the riparian forest in the Corumbataí River Basin. Four main rivers were chosen for this study with three sites on each. Collections were carried out from March to June and from September to December 2001. Multivariate techniques were applied to determine the correlation between species richness and the order of the rivers, preservation level of the riparian forest, shade level, presence or absence of Eucalyptus, sugar cane and pastures, and surrounding declivity stability of the sites. Species richness was highest at locations with greater vegetation cover and preserved riparian forest.

Abstract The aim of the study was the recognition of profile structure and main physical properties of humus-rich endogley soils, which form muddy-alluvial habitats, and soils appearing together with them in a catena developed in the Upper Narew Valley near Sura¿. Plant communities growing on these soils were also recognized. Typological development of the analysed soils is clearly connected with microrelief of flood terrace, water conditions and vegetation cover. The most moisture positions taken by humus-rich endogley soils are overgrown by Glycerietum maximae community. Typic czernozemic alluvial and mucky-like soils with Phalaridetum arundinaceae community are found slightly higher. In the highest and the most dried parts of the analysed terrain mucky soils overgrown by plant community with domination of Alopecurus pratensis appears. Due to lower ash content physical properties of humus-rich endogley soils and peaty-like deposits considerably distinguish from properties of the other soils and deposits founded on the study area.

The development of social relations requires changes in various spheres of human activity and, accordingly, in the relations between the state and society, between the state and the individual. In addition, one of the effective regulators of these relations is a treaty, which can be used in various spheres. To date, the science has not developed a unified view of the contract, and its issues are discussed by representatives of various scientific fields, with the contract being studied as a legal fact, agreement, legal relationship, document and in this regard is defined differently. Moreover, contractual relationship is in constant flux and suffer from changes caused by various factors of legal validity. Therefore, treaty law and the rules governing contractual obligations are given a great deal of attention during improving the process of reforming civil law and ensuring its further effective implementation in the CIS. Within the framework of the conducted research and comparative analysis of the legal bases and practice of application in the sphere of treaty law, the author has formulated grounded positions on the outlined and topical issues, which are as follows: (1) the peculiarities of the use of terminology in the context of the problem of interpretation of contract terms are revealed; (2) identified problems that arise during the termination of treaties in the CIS; (3) the influence of innovative technologies and globalization and the nature of contractual relations in the territory of the CIS countries are established; (4) approaches to ‘smart-contracts’ and a public contract are disclosed; (5) the discussion approaches to understanding the concept of ‘freedom of contract’ are analyzed; 6) a conditional list of the most pressing issues of contract law that arises in the CIS are formed.

Anthropogenic nexus of environmental change is a vital issue in flood control and hazard management. While it is true that some will loom in flood and others in drought, it is no longer valid to argue the authenticity of climate change. Though climate change alters our physical veracities, the problem of yearly flooding is more a human than a natural one in Taraba State. This paper provides technical proof of anthropogenic impression in the incessant flooding in the area. Both spatial and hydro-climatic data were used for this study in addition to designed questionnaire. Hydro and climatic data were collected from Upper Benue River Basin Development Agency, Yola. Correlation matrix was used to show the extent of climatic variation and GIS depicts the land use change. Rainfall has not related well with excess channel flow. Coefficient of variation in rainfall and runoff is not pronounced. R- Factor in all the gauging stations is very low. Built up area occupied just 2.8% of the area accounting for 806.9 hectares. Cultivated area and the bare land was about 13146.2 hectares. This accounts for about 46.3% of the area. Vegetation cover occupied more than half of the study area. This accounts for 50.1% of the land mass of the catchment area under study. Owing to the occurrence of good vegetation cover, which is more than 50% of the basin area, generally one would have expected low occurrence of flooding in the study area. The farmers’ assessment agreed with the scientific analysis. The runoff volumes that traverse the state three decades ago without much disturbance now pose a serious ache. Though Inter catchment link and discharge thereof is a factor, the cogwheel pinpoints land use change and encroachment of floodplain. Parastatals involved in the land survey and planning of the state should wake up to the challenge.


Using comparative legal research method, the author examines the constitutions of the CIS countries, as well as the other post-socialist countries. Over the past nearly three decades that have passed since the collapse of the Soviet Union these countries were in a state of permanent changes in the economy and state-building, guided by the ideas of fiding their own way of development in the conditions of the collapse of the old ideals. The results of such a search are of scientifi interest and fid reflction in the constitutions. The author compares the constitutions of the above-mentioned states by the form, procedure for adopting and modifying them, the characteristics of the state enshrined in them, the form of government, the form of state structure, the specifis of the constitutional status of a person and citizen, and institutional mechanisms for the legal protection of the constitution. A conclusion is made that the application of the traditional approaches to classifiation of forms of government is of little use for the classifiation of the forms of government of states that are attributed to the CIS countries and the Baltic countries (Lithuania, Latvia and Estonia). The author’s classifiation of forms of government in these states is proposed. He also pays much attention to the form of the state structure of the CIS countries and other post-socialist states, including the problem of the existence of unrecognized and partially recognized independent states operating in the territory of some CIS countries and post-socialist states.

The purpose of this study is to determine the state of the vegetation cover in the region of Korhogo through remote sensing. Nowadays, the problem of desertification in the Sahel is serious. This could be explained by the phenomenon of climate change. We want to map the state of the vegetation cover in the study area. This study therefore focuses on the state of the vegetation cover in the region of Korhogo in northern Côte d’Ivoire. We will use one Landsat satellite image from December 16th 2000 and proceed with image processing. Processing techniques by the normalized difference vegetation index, the index armor and colorful composition 472. After these treatments in our pictures, we observe the behavior of vegetation. We can then get an overview of the vegetation in this area.
