The problems of regulating the turnover of agricultural land in private ownership, namely, land shares owned by individuals, but not allocated in kind, are considered. It is proposed to create an electronic thematic map of a land plot containing information on the number of participants in the right of common ownership of a land plot, the size of t...

The use of forest resources in the context of globalized markets and implementing new technologies, enhanced competition and increasing environmental restrictions require reliable information. The method of aerial laser scanning opens up great prospects for the state inventory of forests. It is successfully used in many sectors of the economy, but...

Due to the global warming of the climate, the assessment of the carbon cycle in forest ecosystems has become particularly important. One method for determining deposited carbon is based on the use of biomass expansion factors (BEF) and State Forest Inventory (SFI) data. By combining BEF models with SFI data in two ecoregions of Russia – taiga and f...

Remote registration of such taxation indicators of trees as crown width and tree height has become widespread in assessing the biomass of trees. There are many allometric models of the biomass of different tree species in different climatic conditions, but for the assessment of biomass by remote methods, they are presented in single publications. T...

The chapter describes the conditions of predisposition of territories to the emergence of forest fires on different continents of the world. Information on the types of forest fires and the characteristics of burning materials is given. Human and economic losses from the forest fires and other emergencies (earthquake, flood) are compared. The cause...

Over the past two decades, active airborne laser sensing technology has been intensively used to scan the forest cover, providing such morphometric indicators of trees as the width and projection area of the crown, the height of the tree. The author’s database of harvest data of 1550 model trees of genus Picea spp. of Eurasia is used in the work. A...

Forest ecosystems, as sinks of atmospheric carbon, play an important role in reducing greenhouse gas release and preventing air temperatures from rising. Simultaneously, climate change entails changes in forest cover. We describe the change of Betula spp. stand biomass (tha ⁻¹ ) along the trans-Eurasian gradients of rainfall and temperature using t...

It is necessary to increase the informational supply of land-use planning so it causes the significance of investigation. Different cartographic materials are important part of this supply. For reaching this goal, authors developed the method of landscape diversity cartographo-mathematical modelling using GIS-technology. During the process of inves...

In the process of forest management in a particular constituent entity of the Russian Federation, unique regional features have formed that increase the effectiveness of forest management, the multi-purpose use of forests, their conservation, protection and reproduction, due to landscape-geographical and economic reasons.The aim of the research is...

The article provides an overview of various methods for assessing the forest fund infrastructure during cadastral valuation, including a couple of possible methods of mathematical modeling, with the help of which it is possible to assess the impact of the forest fund infrastructure on the cadastral value, as well as the advantages and disadvantages...

The article focuses on question of public easements’ establishment for forest areas intended to accommodate seasonal roads as temporary structures. On one hand, seasonal roads are transport routes, which location changes every season. At the same time, they have features of real estate items as they are inseparably linked with the ground surface, a...

The article discusses the main directions of forest policy in the field of creating forest fund infrastructure, provides foreign experience in accounting for infrastructure and comparative indicators. An analysis of the transport infrastructure of the forest fund was carried out, as well as a methodology for assessing the infrastructure. Based on t...

The article focuses on the question of temporary logging roads' studying as real estate items. The relevance of research is proved by need of effectivization of land and forest resources use while road infrastructure seating. Strategic aim of research is advanced technology development of compartment description of temporary logging roads. The main...

The first attempt of modeling changes in additive component composition of biomass of Larix sp. communities on the Trans-Eurasian hydrothermal gradients based on regional peculiarities of age and morphology of the forests is attempted. The increase of all biomass components of the tree layer with increasing temperature at the constant precipitation...

Value of forest ecosystems’ natural potential is examined as composition of forest resources (timber and non-timber forest products) as natural capital. Also, value is examined as composition of environment-forming and social functions of forest objects as part of ecological potential of forest areas. Regional (national) richness includes all natur...

The real estate market and features of real estate price formation depend on a large number of economical, social, political, natural, demographic and other factors. In each separately taken settlement, the degree of influence of each group of factors is different, which is largely determined by the features of the city. The object of the present r...

Vietnam is a country of mountains and plateaus, where plains occupy only a quarter of the territory but play a crucial role in the life of the country: most of the population, main cities, industrial enterprises and agricultural lands where rice is grown are concentrated here. Tien Hai is a coastal district of the country involved in the agricultur...

Приведены результаты многолетних наблюдений за почвенно-грунтовыми условиями парка «Сосновка», который расположен в Выборгском районе Санкт-Петербурга. Первоначально в составе насаждений преобладала сосна, но в связи с изменением почвенно-грунтовых условий произошла смена на мелколиственные породы. Изучены основные факторы, определяющие почвенно-гр...

Due to unstable economic situation in Russia, there is a high rate of change in indicators of city-forming enterprises economic activity. It has significant effect on ecological, social conditions of monotowns as well as on economic conditions related to real estate prices. Assessment and forecasting the influence of the city-forming enterprise eco...

Relevance of the study is determined by the absence of the government approved method of state cadastral evaluation of forestlands and major divergence between methods of private valuation agencies. The main aim: of the study is to develop the method of cadastral evaluation of forestlands which can consider individual aspects of minimal inventory i...

The authors analyze expansion of segetal and ruderal vegetation on agricultural lands in Leningrad and Tomsk oblasts, typical for the European and Asian parts of Russia. The spreading conditions, composition of species, biological features and ecological requirements of the most aggressive species are identified. Some effective ways of weed control...

Cadastral appraisal of forest fund is one of the topical challenges of modern natural resource management. The paper delivers comparison of different approaches to cadastral appraisal of forest lands. The authors suggest a uniformed model to compare objectively and choose the most effective use of parcels.

Cadastral valuation of forestlands is poorly developed in Russia. Current methods of evaluation either depend on the probability of harvesting or do not differentiate forest areas by forest stand properties. In this study authors propose to use forest inventory data as a basis for cadastral evaluation of forestlands. At first, forest inventory data...

Cadastral valuation of forestlands is one of the problems of the modern economy. Valuation procedures depend either on the profitability of timbering or forest areas are not differentiated according to value. The authors propose the procedure based on taxation indices of strata. The most important factors influencing the valuation are determined. T...
