Environmental Impact of Shale Oil and Gas Extraction
The article considers environmental problems arising from the hydrocarbon production by fracking. It is shown that almost everywhere shale gas and tight oil are being extracted without a preliminary research on the environmental health, which, in its turn, does not allow recognizing ecological deprivation associated with unconventional hydrocarbon resources development. We dramatically lack the scientific knowledge required to assess potential risks of pollution. The declared ecological advantage provided by shale gas flaring versus coal and oil production is groundless. The obtained findings point out the necessity to examine local conditions when assessing the environmental impact of fracking. The reason is that the effects vary by region. In a similar way, the technology and extraction practices applied at a certain deposit will not essentially be applicable at another one. The authors believe that the antipodal environmental impact assessments of shale oil and gas extraction not only reveal the need for serious scientific research in this area, but also expose the importance of studying the past experience in order to manage the newly emerging environmental risks.

On the issue of water resources export from Siberia
Due to the fact of renewed interest to the project on transbasin water transfer from Ob-Irtysh Basin to the Central Asia countries widely discussed in the 1970s up to the first half of the 1980s, we analyze whether this project was reasoёnable, and show the principle methodological errors made in it. We describe the legal foundations of projects on transbasin water transfer as well as a procedure of ecologic-economic assessment which are necessarily be complied with and made. We question the economic and ecological wisdom of this project at present.
