EDMONd 1Department of Earth, Atmospheric and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA 2Laboratory of Erosion and Fluvial Processes, Department of Geography, Moscow State University, Moscow, Russia (Received June 11, 1997; accepted in revised form February 12, 1998) ABSTRACT—The response of continental weathering rates to changing climate and atmospheric PCO2 is of considerable importance both to the interpretation of the geological sedimentary record and to predictions of the effects of future anthropogenic influences. While comprehensive work on the controlling mechanisms of contemporary chemical and mechanical weathering has been carried out in the tropics and, to a lesser extent, in the strongly perturbed northern temperate latitudes, very little is known about the peri-glacial environments in the subarctic and arctic. Thus, the effects of climate, essentially temperature and runoff, on the rates of atmospheric CO2 consumption by weathering are not well quantified at this climatic extreme. To remedy this lack a comprehensive survey has been carried out of the geochemistry of the large rivers of Eastern Siberia, the Lena, Yana, Indigirka, Kolyma, Anadyr, and numerous lesser streams which drain a pristine, high-latitude region that has not experienced the pervasive effects of glaciation and subsequent anthropogenic impacts common to western Eurasia and North America.

There has been considerable internal debate over the best strate- Accepted 15 May 2015 gic approach to such a relationship. While a policy victory has been won by a strategy focusing Available online 29 October 2015 on the export into the region of manufactured goods and services, a resource-export strat- egy is still dominant in practice and funding. Here the prospects of each strategy are assessed. Keywords: Regarding resource exports, hydrocarbons, copper and iron ore prospects are reviewed, but Russian Far East most detail is provided on the coal sector. That involves an account of infrastructure issues, Asia Pacific Region Coal exports including a major debate over the expansion of the BAM and TransSiberian railways. The BAM analysis suggests that Russia will struggle both to revitalise the Russian Far East through TransSiberian railway manufacturing exports to the APR and to replace revenues earned through resource exports to the West through an economic ‘turn to the East’.

    How to use the Atlas The Atlas has two map sections The Main Section shows the location of Russia’s intact forest landscapes. The Thematic Section shows their tree species composition in two different ways. The legend is placed at the beginning of each set of maps. If you are looking for an area near a town or village Go to the Index on page 153 and find the alphabetical list of settlements by English name. The Cyrillic name is also given along with the map page number and coordinates (latitude and longitude) where it can be found. Capitals of regions and districts (raiony) are listed along with many other settlements, but only in the vicinity of intact forest landscapes. The reader should not expect to see a city like Moscow listed. Villages that are insufficiently known or very small are not listed and appear on the map only as nameless dots. If you are looking for an administrative region Go to the Index on page 185 and find the list of administrative regions. The numbers refer to the map on the inside back cover. Having found the region on this map, the reader will know which index map to use to search further. If you are looking for the big picture Go to the overview map on page 35. This map shows all of Russia’s Intact Forest Landscapes, along with the borders and Roman numerals of the five index maps. If you are looking for a certain part of Russia Find the appropriate index map. These show the borders of the detailed maps for different parts of the country.

  • The Baikal-Amur Mainline Memories and Emotions of a Socialist Construction Project
    The Baikal-Amur Mainline Memories and Emotions of a Socialist Construction Project OLGA POVOROZNYUK Abstract: The Baikal-Amur Mainline (BAM), a railroad in East Siberia and the Russian Far East, became the last large Soviet industrial proj- ect. Its construction in the 1970s and 1980s attracted migrants from across the USSR, who formed the bamovtsy, or group of BAM build- ers. They share a history of working and living along the BAM and constitute the majority population in the region. The article argues that emotionally charged social memory of the BAM construction plays the central role in reproducing and reinforcing the bamovtsy identity in the post-Soviet period. Drawing on in-depth interviews and focus groups, the article examines the dynamics of both indi- vidual and collective remembering of the socialist BAM. It forms a vibrant discursive and emotional field, in which memories and iden- tities are reconstructed, relived, and contested. Commemorative cer- emonies such as the fortieth anniversary of the BAM serve as forums of public remembering and arenas for the politics of emotions. Keywords: Baikal-Amur Mainline, emotions, identity, politics, post-socialism, social memory he Baikal-Amur Mainline (BAM) is the longest northernmost rail- road crossing the regions of East Siberia and the Russian Far East Tto link the Eurasian countries with East Asia. The history of the BAM starts with early construction projects dating back to the nineteenth century and continues with the first tracks laid under the Stalinist regime in the 1950s. However, the majority of the mainline was built between 1974 and 1984, under the authority of the Soviet industrial pro- gram focused on “mastering the North” (Slavin 1982).
