“…In order to do this, studies on plant, pedological and climatic dynamics are required, highlighting the need to perform the restoration of the semi-arid environment from scientific evidence on the functional characteristics of plant species concerning the environment in which they will be inserted [48][49][50]. Thus, projects aimed at protecting, conserving and/or regenerating the vegetation of the caatinga biome in semi-arid basins will be more efficient and financially viable when planned and structured based on scientific evidence (taking as an example the studies presented herein) [4,16,45,[48][49][50][51] seeking to understand the existing geoecological interactions that configure the landscapes [3,20,26,27,30]. In this sense, geoecological adequability indexes, when used to estimate adequate and inadequate areas for anthropic uses for the studied semiarid basins, comprise a flexible classification that is easy to apply to other environments, and can be used as a proxy for the design of public policies, such as payment by environmental/ecosystem services in basins, mainly in areas that still remained conserved.…”

“…Many of these gaps are overcome with the use of Geographic Information Systems, which allow for the modeling of remote sensing data, highlighting LULC mapping, Normalized Difference Vegetation Index (NDVI) and integrated studies based on thematic cartographies to verify water availability and groundwater recharges [2,3,8,9,[18][19][20][21]. Specifically regarding the use of NDVI, this index makes it possible to identify vegetation cover patterns, as well as spatial and temporal analyses of phytogeographic dynamics, monitoring water soil availability, land uses and drought effects [2,19,[22][23][24][25].…”

stract This research aimed to perform a comparative analysis of Geoecological Adequability (GA) in two semi-arid watersheds in Northeastern Brazil based on a classification carried out in a GIS (Geographic Information System) environment using the algebra map tool. The GA calculation reveals the interactions between landscape components through GIS, namely soil, slope, vegetation and land cover. Weights were assigned (1, 2 or 3) to the different cartographic layers of the geoecological components measured using the algebra map tool, through the arithmetic means, to classify the semiarid basins into different adequability levels, as follows: adequate, partially adequate and inadequate to anthropic uses. These procedures verified the predominance of the “adequate” class with a territorial area above 42% in both investigated basins; the “partially adequate” level and the second most comprehensive class comprised values between 30% and 40%; and, while smaller territorial extensions, below 20%, were “inadequate”. Based on these findings, it was possible to measure the most suitable areas for anthropic use in the studied basins and indicate the areas that should be conserved, with emphasis on protection and/or regeneration of the natural vegetation cover. This is important information concerning the planning and environmental management of these semi-arid landscapes in an objective and efficient way

“…The practice of construction in Siberia in the 70s-80s and the results of numerous surveys of the SoyuzdorNII (Research Institute) and experts from the Research, Development, Production and Diagnostic Center in the north of the Tyumen region point to the high efficiency of using reinforced soils in road structures on roads and at airfields [12][13][14][15]. Thus, the service life of road pavements to overhaul on the Tyumen-Tobolsk highway was 28 years, and on the runways of airports in Nadym, Surgut, Nizhnevartovsk, and Tyumen it ranged from 24 to 31 years.…”

“…Over the past fifteen years, foreign scientists have obtained a number of surface-active additives (surfactants), actively influencing the formation of road-building materials. On the basis of the Industrial University of Tyumen, scientific and practical studies were conducted on the effect of additives and stabilizers of foreign production in strengthening the soil [15][16][17]. The encouraging results of improving the physical and mechanical properties of reinforced soils were obtained.…”

The paper presents the history of the transport infrastructure of the West-Siberian oil and gas complex in the last century and ways to solve the problems of road construction in the twenty-first century. The development of the territory of Siberia and the North in the present period is constrained by the low rates of development of the transport structure. One of the reasons for this lag is the lack of regulatory documents to substantiate transport structures in the harsh climatic and difficult soil and geological conditions based on the use of new modern road-building materials. The development of new resource-saving materials, structures and technologies based on local building materials, products and industrial waste using modern methods and research methods in materials science is an aim of current study. The general research methodology consisted of theoretical, laboratory and field studies. The developed designs and technologies for the construction of embankments in permafrost and in swamps using geotechnical holders filled with unsuitable soils (thawed and frozen waterlogged peat and clay soils) can reduce the volume of work and the cost of construction by one and a half to two times while increasing the service life of structures. The experimental sites of embankments constructed between 1995 and 2009 in the wetlands of the Uvat Group of deposits in the Tyumen Region and in permafrost in the areas of Novy Urengoy have been observed for more than ten years. The artificial stone material tested in Murmansk and Surgut based on the strengthening of local soils with inorganic binders with polymer additives using modern technologies allows it to be used instead of imported stone materials and reinforced concrete slabs for the construction of structural layers of road pavements, reinforcing slopes, as well as in hydraulic structures. The new artificial stone material is characterized by high strength and durability in areas with a temperature gradient of the external environment of more than 100 (from +50 to -50 °C).
