In order to implement environmental protection, within the Soil Cadastre, previously proposed as a multipurpose inventory that aims to promote sustainable soil uses, the hydrogeological instability caused by human activities is the focus of this work. These activities can be aimed at sustainable agricultural soil use or the building of roads to allow the access to the fields. The soil’s hydrogeological instability causes the unsustainable use and management of a cadastral parcel. Therefore, the aim of this work is to propose a nomenclature for hydrogeological instability risks, as well as the best practices of conservative soil tillage in case studies, in order to reduce environmental impact. According to the proposed Soil Cadastre, the missing environmental sustainability of a parcel and the reason for this must be communicated to the field owner or manager. In a hilly area of inland Western Sicily, four main risk types of hydrogeological instability were identified: hydrogeological instability (caused only by natural factors); hydraulic-pedological farming instability (crop not suitable for the field for missing or insufficient soil drainage and landslides); hydraulic-infrastructural instability (built up infrastructures unsuitable for the site); hydraulic-infrastructural-pedological-management instability (field improvements changing the downflow line and crop operations not suitable for the soil and climate parameters). The farm owner or manager must be informed about the risk type affecting their fields in order to perform the best practices (i.e., conservative soil tillage), for implementing or restoring a sustainable soil use or management in each cadastral parcel.

Based on the cross-sectional data of 40 large-scale international airports in China in 2019, this paper introduced natural and social factors into the calculation of airport operating efficiency and constructed a BCC-SFA-BCC-Tobit 4-stage analysis framework. Combining with the connotation of the “green, smart, humane, and safe” airport high-quality development, the paper applied the Tobit model to quantitatively analyze the influencing factors of the operating efficiency of airports, and the research shows that (1) the overall operating efficiency of the study airports is 0.734; in terms of the region, the operating efficiency of airports located in southwest and northwest regions is greatly affected by natural factors, while the operating efficiency of airports located in North China is mostly affected by social factors. (2) Under the perspective of human-earth relationship, the impact of natural factors on the operating efficiency of airports is greater than that of social factors, wherein PM2.5 and relative humidity have negative impact, while the actual foreign capital utilization of the city and domestic and foreign tourists have positive impact. (3) The regression results of the Tobit model indicate that green, smart, and safe indicators can promote the high-quality development of airports, while the humane indicator restrains the high-quality development of airports.

The prolonged availability of seafarers on board of water vehicle during voyages forms the features of professional labor activity. When assessing the medical and sanitary situation of life and vital activity of the crew on board a ship, it is necessary to take into account a set of conditions that are integrated into a single notion — «ship environment ». The ship’s environment affects the personnel’s body for the entire period while people are on the voyage. It can cause changes in the state of health. The article presents a review of the literature devoted to the study of the influence of climatic and geographical factors accompanying maritime labor. Natural factors occupy a significant share among the large effects of the ship’s environment that affect the health of seafarers and, accordingly, their ability to work. Among them, the greatest contribution is made by temperature, physico-chemical properties of air, photoperiodic fluctuations. The homeostatic systems of the seafarers ‘ body are very closely dependent on the natural situation of the seas. These conditions impose high requirements and can cause the development of premorbid and pathological conditions. To ensure the protection of the health and working capacity of the crew, it is necessary to study the influence of external factors. The main directions for ensuring the safety and strengthening of the health of seafarers are: forecasting and prevention of health disorders, prenosological diagnostics and timely medical support, rehabilitation measures in the post-voyage period.

Abstract Remote sensing (RS) and Geographic information system (GIS) is widely applied in the world and gradually affirms its role in Vietnam in managing agricultural and forest resources. This application is highly effective, providing information timely for managers to make decisions and build development strategies. In this study, RS and GIS were integrated to assess suitability for key crop species in Dak Nong province including coffee, rubber, cashew, and durian based on their suitability to site conditions such as soil (soil type, soil texture, soil thickness), topography (elevation, slope) and climate (temperature, precipitation). Using the restrictive method and overlapping map layers of natural factors, classified into adaptive levels according to FAO (1976). Results show that most land areas in Dak Nong province have different levels of potential suitability for key crop species ranging from non-adaptive to lesst-adaptive and moderately adaptive. However, most suitable areas for key crops are only at low (accounting for a large proportion) and the average adaptation level. The findings from the study are the scientific information for managers to make decisions regarding the structure of major crops in the province.

Some unfortunate brothers were baptized to feasts and banquets for the public, and during season times Historical sources ndicate that the cults of the Abbasid Caliphs, including the Abbasid aliphate Al-Mahdi, the Mamoun and the Mu 'taad, ranged between six thousand and a thousand dinars a day, while the expenses of the Al-Mutakil kitchen amounted to one thousand dirhams, which is a fairly large budget. He was also known to identify the Abbasids with public and rivate tables, including the Caliph al-Mansur Al-Rasheed al-Mamoun with a stature favourable to the general public in addition to the state of development that Arab and Islamic society witnessed during the Arab era, in terms of the literature of the gourmet and the pious tools related to the Arab cuisine Result for Tth.

The research of forest cover development on agricultural lands in the Perm Prikamye was carried the example of taiga and forest-steppe types of landscapes. The Babkinsko-Yugovskoy and Irensko-Kungursky landscapes were select for research. Received information about the geosystem condition in different years using remote sensing data. All landscape changes were record during the formed stable snow cover. As a result, was divide into two classes - forested and treeless areas. Established, the main natural factors of land differentiation by an areas and a pace of withdrawal from agricultural use are the small contours of agricultural land and differences in soil fertility. The growth pace of forest geosystems within the forest-steppe landscape was 2.5 times higher than of the taiga. The research of the dynamics of forest cover showed that in the Perm Prikamye in the forest-steppe landscape substitution of anthropogenic geosystems with natural-anthropogenic ("wild") accompanied by the development of forest biogeocenosis, not steppe.

According to the results of bird counts carried out in 138 habitats over 12 years, a hierarchical classification and a structural graph of the similarity of ornithocomplexes in the plain southwestern part of Western Siberia and Northern Kazakhstan have been compiled in the period from 1982 till 2002. The hierarchical classification contains six types of bird populations. The similarity graph is built at the level of types and is represented by three rows (trends). One row consists of bird complexes of residential and recreational areas; the second, of wetlands; and the third, of forest, forest-field, and steppe habitats. The classification taxa characteristics contain information on the three most numerous bird species (leaders in abundance), their share in the community, population density, and the background species wealth. Based on the assessment of the similarity coincidence degree for the of bird communities and environmental factors, a hierarchy of the impact of the main anthropogenic and natural factors, determining the bird population formation, has been established.
