Climate change is expected to have impact on water supply and drinking water quality in Iceland. Foremost there are three influential weather-related factors; increase in temperature; rise in sea level; and seasonal and regional change in precipitation in both quantity and intensity. In this study international and local reports and articles were analyzed for expected impact on the water resource with emphasis on the northern and the arctic region. Water quality risk factors were analyzed based on surveillance data of the water supplies from the Local Competent Authorities. Preliminary risk assessment of landslides and flooding was performed in one surveillance area in northern Iceland.

The methodological approaches and the results of assessing the environmental risk level in river ecosystems of the Arctic region of Russia was presented. Assessing of the environmental risk level in ecosystem includes identifying possible negative consequences of anthropogenic impact, which are appeared in a violation of the structural organization of biocenoses. An intensification of the ecological devolution of individual communities of aquatic organisms is observed in modern conditions of anthropogenic impact and climatic variations in the Arctic ecosystems of rivers. The tendency to increase the ecological devolution level as the anthropogenic impact intensifies during the transition from less polluted Arctic rivers to more polluted ones (dirty) has been revealed. The ecological devolution level varies from absence (anthropogenic stress) to its appearance in the form of elements of ecological devolution. The results of the final assessment of the environmental risk level in the ecosystems of the Arctic region of Russia according to the ecological devolution level showed that the studied sections of the rivers are characterized by a low and medium level of risk. Further enhancement of anthropogenic impact on the catchments of Arctic rivers can lead to disruption of the ecological state of aquatic ecosystems and intensification of ecological devolutions processes which may increase the level of environmental risk.

The use of branched-hole wells in old fully developed oilfields permits to increase hydrocarbons production at the expense of involving the undrained areas in development. The most wide experience of multihole wells operation in Russia was gained in oil fields; and in gas fields the construction of such wells was launched in the field Yujno-Russkoye, West Siberia. The gained experience in designing, construction and operation of multihole wells in the Extreme North fields will enable to recommend these designs in the Arctic region conditions including offshore fields.

The article deals with the problem of the development of the domestic nuclear icebreaker fleet in the context of the implementation of nuclear logistics in the Arctic. The paper analyzes the key achievements of the Russian nuclear industry, highlights the key areas of development of the nuclear sector in the Far North, and identifies aspects of the development of mechanisms to ensure access to energy on the basis of floating nuclear power units. It is found that Russia is currently a leader in the implementation of the nuclear aspect of foreign policy and in providing energy to the Arctic region.
