The research deals with the issue of slums, urban sprawl on agriculture land and its impact on the city of Baghdad. This topic needs close attention because it has become a problem facing the city of Baghdad through recruiting agricultural lands and converting them to residential homes in addition to the transgression on the state lands and building abuses. This research deals with the causes of slums, irregular urban sprawl and risks of excesses on land uses of land in Baghdad. In this research, we try to know the extent to which these problems have affected the city of Baghdad. The research methodology based on the descriptive methodology to clarify the factors affecting urban sprawl at the expense of agricultural land, using studies in government and service institutions and images from satellites to clarify the size of urban sprawl over periods after the 2003 war. Finally, a conclusion and future solutions were set to solve these problems.

Biodiversity analysis underlies macroevolutionary studies and allows to identify mass extinctions. Numerous studies of mass extinctions show that geological factors play a central role in determining the diversity dynamics. The late Cretaceous extinction is of interest to science as the closest to us extinction of the five mass extinctions that occurred in the Phanerozoic. There is currently no scientific consensus on the scenario in which the extinction occurred on land. In order to assess the features of superorderDinosauriadevelopment during the Cretaceous-Paleogene, the authors have analysed the diversity of terrestrial taxa of Mesozoic dinosaurs. Based on data from the paleobiodb paleontological database using the Python programming language and its libraries, the features of the species diversity ofDinosauriahave been studied. An attempt was made to quantify the species diversity of this group based on the ratio of predators to herbivores using data on dinosaur food types. The simulated diversity data were compared with observed patterns and existing estimates. It is likely that less than one-third of the dinosaurs that existed are currently known, as indicated by the geography of the fossils, and the proportions of dinosaurs by type of diet.

One of the important issues is the assessment of the strength of the elements of hydraulic structures, spillway structures, reservoirs, and hydraulic complexes, the determination of the connection mode of the basins, and the reduction of kinetic energy in the reinforced fields of the downstream pool. In this regard, it is especially important to determine the hydrodynamic characteristics of the flow of water moving in the apron and risberme area, which provides the stability of the downstream pool - the areas that indicate the distribution and direction of velocity and pressure.

The object of the study is the water supply and sanitation system of an industrial enterprise. Currently, many enterprises do not use the treated industrial waste water in the water supply cycle. Therefore, the use of treated wastewater is of practical importance. The scheme of thermal treatment of waste water for obtaining pure condensate by evaporation is proposed. The main results of the study are the technical solution for the development of the enterprise's wastewater treatment complex. Pure condensate is obtained in an instant boiling evaporator. The research method is based on the calculation of energy costs in wastewater treatment for different types of waste water. The results of the study allow us to determine the optimal set of energy equipment for obtaining pure condensate and its further use. The specific practical significance lies in the development of a technical solution that helps the treatment of wastewater and the reduction of emissions into the water basin.

Abstract. This paper discusses the features of such a unique land plot type as the unified land use. This type of a land plot appeared by virtue of the Russian Federal Law No. 28-FZ “On the State Land Cadastre” dated January 2, 2000. However, the current land legislation does not contain such a term. Currently, the unified land use cannot be formed, but previously registered land still exists in the state cadastre. In addition to a number of features in the land register procedure, the unified land use has no restrictions and freely participates in civilian circulation. Land plots that are the unified land use may be subject to all types of transformation specified in 11.9 of the Land Code of the Russian Federation, with the transformation into two types: the so-called ordinary plot and multi-contour land plot. It should also be noted that there is no term of multi-contour land plot in the land legislation. Some authors draw an analogy between the unified land use and a multi-contour land plot. However, there are a number of differences.

The study discusses the impact of open cuts for the extraction of common minerals on soil resources and agricultural lands in Moscow region (MR). For this, the features of soil cover in Moscow region and the distribution of soil types by their use as agricultural resources were analyzed. Further, it was determined which types of soils are subject to varying degrees of open cut load. As a result, a schematic map of the soil cover with open cut load zones was made. It is shown which agricultural lands exposed to open cuts of varying intensity. A conclusion is made about the types of soil cover, which accounts for the greatest and least open cut load, as well as the degree of impact of open cuts on agricultural land resources and the correlation between the degree of open cut load and type of agricultural land use. It is shown that the most fertile soils, which occupy only 2.9% of the MR area, are not affected by the open cut load at all. The greatest open cut load is associated with agricultural lands, represented mainly by various sod-podzolic soils, which occupy 70.5% of the territory of the Moscow region. If economic trends and population growth rates in the Moscow region continue until 2030, we should expect a further increase in the influence of open cut load on agricultural land towards its intensification.

The authors of the article consider the problem of protection of water bodies from pollution by oily wastewater from the territory of enterprises of the agro-industrial complex engineering and technical systems. A resource-saving technology for this wastewater treatment using multicomponent sorbents has been developed.

The impact of coal mining in Kuzbass on the ecosystem of the region is studied in the article. Large-scale mining operations have led to land disturbance over large areas. The coal industry development program, which provides for a significant increase in production, will further aggravate the identified problem. There are a lot of reclamation mechanisms, they must be implemented comprehensively, be high-tech. Large-scale disturbance of land resources, and land retirement, its pollution and littering are the most significant problems requiring a primary solution. The mechanism of state and regional legal regulation of disturbed land reclamation is proposed. Improving the quality of reclamation will be facilitated by the development of a strategy for the environmental remediation, which would be included into the Concept for reclamation of disturbed lands.
