In this study, we base upon the fact that the relief is the framework of landscape and the basis of scenic composition. The morphometric characteristics of the relief are analyzed as complex indicators of the aesthetic assessment of the territory. These are the position of the observation platform in the relief, the prevailing steepness, the exposure, the shape of the slope in the plan and ruggedness of the relief. The algorithm for calculating indicators in the QGIS software package using the GRASS GIS and SAGA GIS modules is presented. The artifacts of the initial values of the SRTM height matrix are eliminated to improve the accuracy of the calculation. An important evaluation criterion at arranging tourist and recreational activities is the proximity to the main traffic routes. In accordance with the human body loads advised and indicators of hiking comfort, buffer zones around highways and railways are created. Basing upon the obtained data of the surface slope and distance from traffic routes, a map of the integral proximity of observation platforms is created. The implementation of the GIS analysis procedures is carried out on the basis of the landscape-and-typological map contours. The study was conducted for the Central Ecological Zone of the Baikal Natural Territory within the administrative and territorial boundaries of the Irkutsk Region 1

Socio Economic Development

The article deals with the current demographic, economic, social, and environmental problems of three districts of the Irkutsk Region, which are part of the Central Ecological Zone of the Baikal Natural Territory. The study was conducted using statistical data from the Federal State Statistics Service, articles and monographs on the topic under consideration, data from sociological surveys, mass media, and information obtained during a scientific expedition to Lake Baikal, in which the author participated. The socio-economic development of municipalities within the boundaries of the Central Ecological Zone of Lake Baikal remains difficult due to environmental legislation that restricts the economic development of the territory. The inability to fully use land resources provokes the local population to migrate. Tourism is one of the few economic activities permitted in the coastal area of the Lake Baikal. Despite the growing number of tourists visiting the region every year, the weak level of economic diversification of the municipalities threatens the prospects for sustainable socio-economic development. The region risks losing most of its revenue in the event of political, economic, or epidemiological shocks. The development of other types of economic activities will contribute to the socio-economic security of the areas under consideration. This is also influenced by the demographic potential of the territory – the employment of local residents and the training of personnel will allow us to effectively implement alternative directions of economic development. It is also important to develop other types of economic activities in connection with the negative impact of tourists on the ecosystem of Lake Baikal. The revision of the approaches to the economic, social, and environmental policies carried out in the region is an urgent task today

Abstract The research considers the results of the aesthetic assessment of landscapes in the central ecological zone of the Baikal natural territory (CEZ BNT). The expert assessment based on a set of indicators was carried out in Quantum GIS using landscape photographs. Cartographic materials (landscape typological map, Forest Resource Management maps, SRTM, areas affected by fire, etc.) were also involved in the assessment. The map «Aesthetic Evaluation of the Geosystems of the Central Ecological zone of Lake Baikal within the Borders of the Irkutsk Region» was created based on the analysis of the estimated indicators of the aesthetic landscape quality. The construction of the map is based on the principle of the priority of landscape scene viewpoints; the assessment is assigned to the polygon from which the landscape scene is observed. The article contains the detailed structure of the landscape scene complexes of the CEZ BNT.

The article describes a comparison of the standard method of designing logging roads and public roads using drawings and sheets on paper with the design of logging roads and public roads using information modeling technology. The results achieved (interaction structures, formation of information models, organization of collective work, etc.) in the development of the following “pilot” objects are also described: plans for the development of the section of the R-258 Baikal highway under the jurisdiction of the FKU Uprdor “Southern Baikal” in the central ecological zone of the Baikal Natural Territory; major repairs of protective road structures on the R- 258 “Baikal” highway Irkutsk-Ulan-Ude-Chita at km 157+500, Irkutsk region; major repairs of the M-5 Ural highway Moscow-Ryazan-Penza-Samara-Ufa-Chelyabinsk, access to Yekaterinburg on the section km 79+899-km 121+509.

Field trials were conducted in the wet seasons of 1997 and 1998 at Makurdi, Otukpo and Yandev in the Southern Guinea Savanna ecological zone of Nigeria to study the responses of ten soybean genotypes to intercropping. The experiment was laid out in a randomised complete block design. The genotypes TGX 1807-19F, NCRI-Soy2, Cameroon Late and TGX 1485-1D had the highest grain yield. All the Land Equivalent Ratio (LER) values were higher than unity, indicating that there is great advantage in intercropping maize with soybean. The yield of soybean was positively correlated with the days to 50% flowering, days to maturity, plant height, pods/plant and leaf area, indicating that an improvement in any of these traits will be reflected in an increase in seed yield. There was a significant genotype × yield × location interaction for all traits. This suggests that none of these factors acted independently. Similarly, the genotype × location interaction was more important than the genotype × year interaction for seed yield, indicating that the yield response of the ten soybean genotypes varied across locations rather than across years. Therefore, using more testing sites for evaluation may be more important than the number of years.
