Forest is an important natural resource to the Latvian economy. It is useful to examine the historical context to estimate objectively the events that created the structure of forest property rights today. While 50.3% of all Latvian forests are state-owned and the remaining 49.7% are under different ownership, historically this structure has changed with the political situation and the authorities.

Changes in soil morphological, physical and chemical properties as a result of establishing forest on agricultural lands were studied using as an example the lands naturally overgrowing in different periods of time by Norway spruce (Picea abies (L.) H. Karst.), silver birch (Betula pendula Roth.), grey alder (Alnus incana (L.) Moench) and aspen (Populus tremula L.). The research results showed that the soil with a texture of sandy loam and loam retains the morphological properties of agricultural land for up to 100 years.

The main tasks of the reclaimed and soil science have been formulated. It was noted that the radical and final reorientiring of the reclaimed and soil science as a whole in the country is necessary to working out the science methodology of support and effective functioning of the acting reclaimed complexes and systems. It is necessary to expand researches on microbiology, biochemistry and biophysics of agricultural lands with the purpose of the long-term strategy of the fertility, productivity and land immunity improvement.

The primary aim of this paper is to determine the most common contemporary meaning of the terms most often used to characterise international real estate transactions. The synonyms of the terms “international”, “real estate”, “transactions” or terms used in research literature with similar meanings were identified during the research.

In this paper solutions are proposed to improve the performance of a wheeled robot for rural environment. These solutions can be used for a wheeled mobile robot that moves upon curved surfaces, surfaces with irregularities and small coefficient of static friction between the wheels and the surface. The design and control of the robot are based on a new concept of a wheeled mobile robot, which can work in two different modes.

To justify the importance of the indicators affecting the cadastral value, surveys were carried out, by help of which opinions of different respondent groups were summarized. The interviewed respondent groups were real property specialists of municipalities and experts. The thematic blocks of the questions included in the questionnaires are designed with the aim to clarify the quality of the indicators of cadastral assessment models, as well as their significance.

The Belgian climate policy is formulated at the federal level, requiring cooperation between regional and federal administrations. Around a fifth of the total area of Belgium is covered by forests. Around 80/ of the productive forests are in the Walloon region. Reported values for land use change and forestry categories give a potential of 2,057 kt eq. CO2 per year. Given the existing regional forest inventories (RFI): RFI1 for 1984 and RFI2 for 1999, an estimate has been made to consolidate reported data.

The Large-scale Biosphere-Atmosphere Experiment in Amazonia (LBA) is a multinational, interdisciplinary research program led by Brazil. Ecological studies in LBA focus on how tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in the Amazon region. Early results from ecological studies within LBA emphasize the variability within the vast Amazon region and the profound effects that land-use and land-cover changes are having on that landscape.

In agricultural industry of the Republic of Belarus the problem of increasing the effectiveness of utilization of land resources appears one of the most actual. Annual alienation of agricultural lands and arable fields under housing construction and industrial buildings, roads and other economic object leads to implacable decline of agricultural areas. Absence of new lands, suitable for agricultural use, promotes increase of agricultural productivity by means of intensification of producing process.
