The article provides a theoretical base for the regional strategy in the field of ecological safety in the Republic of Crimea and shares results of medico-ecological monitoring based on systematic approach for many years. Defined environmental safety priorities in the Crimea and described scientific and practical results of the implementation for some of them. According to medical statistics, the dynamics of morbidity of the population for the last 20 years is analyzed and relative risk is estimated in different cities and administrative districts for the morbidity overall and the most environmentally-related diseases (congenital anomalies, cancer, respiratory diseases). Field studies results of the environmental situation for the nitrogen oxides and sulfur as the main atmospheric pollutants are provided based on governmental hygiene and European environmental standards. Further steps are indicated for the successive solving of health issues and environmental problems, and assessment of environmental health risks in the Republic of Crimea.

The geoecology of Chelyabinsk is characterized and assessment of arsenic contamination of its water ecosystems by content analysis of this substance by nuclear-absorbing speсtrophotometer method in rain and surface water, hydrophyte and bottom sediments is carried out. Results of the analysis showed that arsenic content in rain and surface water was though is lower than its maximum permissible concentration, but one order of magnitude that unambiguously points on significant contribution of atmospheric precipitations in contamination of river and lake water by this element. In the given case arsenic content increased on current course of the Miass river in water by 1.5 times, in common reed grass by 1.3 times, and bottom sediments by 2.1 times that testifies about increase of technogenic load on this water ecosystem.

Nitrate contamination of water ecosystems of the Chelyabinsk and its vicinities by the content analysis of these substance in underground, surface and rainwater, hydrophytes and bottom sediments is estimated. The nitrate content in underground water (from a well and boring wells) in comparison with surface water (from the Miass River, the lakes Pervoe and Smolino) was above maximum permissible concentration (by 1.7-4.0 times). Increase of nitrate content in the Miass River on course of its current is noted. Hydrophytes depending on a species and place of their dwelling were characterized by various nitrate content.

A geoecological zoning of Siberia due to hazardous geomorphological processes has been developed by the specially developed technique. It is based on: 1) the spatial distribution patterns of the main morphological structures and ongoing geomorphological processes; 2) territorial organization of the economy that is changing dramatically due to changes in the entire system of territorial and production relations in Russia; 3) near-term prospects of social and economic development of certain regions of Siberia and hazardous geomorphological processes that result can be activated or re-emerge. Hazardous geomorphological processes are allocated in relation to specific types of nature-using that prevail in the geoecological regions of Siberia at the moment or are planned in the short term (5-10 years). On the basis of zoning it is possible to set specific objectives to optimize the environmental condition of relief and organization of the economy. Geoecological zoning of Siberia, in the circle of problems solved by the Russian Federation Ministry of Emergency Situations, will contribute to the rationale and implementation of special federal and regional policy necessitates for the creation of an appropriate legal framework.

The contribution is completed in the laboratory of cartography, geoinformatics and remote sensing of the Sochava Institute of Geography (Irkutsk) in the framework of the electronic Ecological atlas of the Lake Baikal Basin. We solve the fundamental scientific problem concerning the creation of base maps of the natural environment for the territories of two sovereign states - Russia and Mongolia to support a development strategy for a large region and predicting its environmental impacts on the basis of representations about the functioning and dynamics of geosystems of Siberian scientific school of geographers. A specialized classification of geosystems is developed, which reflects both morphotypical and functional and dynamic features, allowing to assess their sensitivity and ecological sustainability as well as to support the transition from the inventory phase of the study to forecast the future state of geosystems. The cartographic analysis of geosystems structure on the geoms level is carried out and electronic maps are created: a basemap "Geosystems of the Lake Baikal basin" and its derivative map "Sensitivity of the geosystems of the Lake Baikal basin", 1: 5 000 000. They can provide information support for addressing environmental problems of a large region.

Possibilities of using landscape-estimated mapping for the analysis of environmental risks are shown. The main approaches to drawing up landscape-estimated maps and regional features of landscape-estimated mapping are considered

A large number of objects of past environmental damage formed on the territory of the Russian Federation as a result of unsustainable economic activity. According to various estimates, the total area of polluted areas is about tens of thousands of hectares. Toxic chemicals, which are concentrated in the contaminated areas, are the source of the negative impact on the environment (soil, surface and ground water, air), which can lead to a significant deterioration of the ecological situation. At this article we propose to use the methodology of risk analysis to assess the hazard of these objects on the environment. Predictive estimate of the adverse effects of the chemical production ("Production Association Krasnoyarsk Chemical Plant "Yenisei") on the environment and health of the population is made on the basis of the proposed methodology.

The article is devoted to the issues of improving investment attractiveness of enterprises through the analysis of geoecological risk (GER) and ratings. The authors reveal the necessity of using these approaches, given contemporary investment climate in Russia. Special attention is paid to the environmental ratings as the elements of the system of corporate responsibility. Also the authors suggest using the concept of GER analysis on the example of oil and gas enterprises in the Russian Arctic. As for investing, the main advantage of this concept is making the most effective investment management decisions based on quantitative estimates of the GERs magnitude, determination of their likelihood, especially in the areas with low information availability and a high degree of uncertainty.

In article attempt on the basis of synthesis of literary data and own works on studying of experience of overcoming of serious consequences of the Chernobyl accident to define those scientific problems which were solved during recovery from the accident, the subsequent ecological rehabilitation of territories and social support of the affected population is made. It is shown what scale of problems of overcoming of consequences of the Chernobyl accident, has demanded the solution of many exclusively complex challenges affecting practically all spheres of public life, many aspects of science, morals and the right. The mankind, for the first time, has faced so large-scale radiation accident, and our country couldn't be ready to elimination of an emergency situation of similar scale. However in this extreme situation rather effective scientific ensuring works has been adjusted that has allowed to carry out quickly all necessary actions for protection of the population, to localize the main sources of radioactive pollution and in the subsequent to normalize a radiation situation on nuclear power plant. Experience of scientific maintenance of works on recovery from the accident promoted creation in our country of the state system of the prevention and elimination of emergency situations and has accelerated progress in development of methods and means of radiation protection of the population.
