    During the Cold War, production and testing of nuclear weapons in the United States and the Soviet Union led to major releases of radioactive materials into the environment. Although large studies have begun to clarify the magnitude and impact of releases in the United States, only since Perestroika has information become available to begin an evaluation of the significance of releases into the environment in the former Soviet Union (FSU). The Radiation Safety of the Biosphere (RAD) Project at the International Institute for Applied Systems Analysis (IIASA), begun in 1995, is currently evaluating the radiation legacy of the nuclear weapons complex in the FSU. Because the three sites of Chelyabinsk-65 (Mayak Production Association - MPA), Tomsk-7 (Siberian Chemical Combine - SCC), and Krasnoyarsk-26 (Mining and Chemical Combine - MCC) account for the vast majority of the radioactive materials released into the environment in the FSU, these sites are the focus of RAD's studies. Contamination of such sites has resulted from normal and emergency atmospheric releases (such as the 1993 tank explosion at Tomsk-7), discharge of radioactively contaminated waste and cooling waters into rivers, spills and leaks, and deep-well injection disposal of liquid radioactive waste. This study is limited to the impact of past discharges of radioactive materials to the Yanisei River at the MCC and the Tom River at the SCC. Future studies are planned to assess the significance of deep-well injection of wastes at the MCC

    Modeling Economic, Social and Environmental Implications of a Free Trade Agreement Between the European Union and The Russian Federation

    The EU-Russia Partnership and Cooperation Agreement, which entered into force in 1997 foresees the possible establishment of a free trade area (FTA) between the parties. The aim of our study is to evaluate the possible economic, social and environmental impact of such a free trade agreement between the European Union and Russia. The results of the analysis indicate that an EU-Russia FTA will be beneficial to the Russian Federation and the EU27. Some sectors are expected to contract in the medium term, but their importance in total output is small. Over the long run, the majority of sectors in Russia are expected to expand, while only a few sectors in the EU27 are expected to register negligible decreases in output. We estimate that welfare losses from the environmental damages would be very small for Russia (possibly even smaller due to the implementation of greener technologies), and negligible for the EU. Despite some significant negative medium-term social implications in selected sectors in Russia, the overall increase in economic activity and wages, coupled with likely domestic policies aiming at easing the impact of transitional unemployment, are expected to allow for the overall reduction in poverty rates. Overall, the results show that significant welfare gains (2.24% of GDP for Russia) would accrue from the deep FTA scenario involving a significant reduction of NTBs along with additional flanking measures, particularly on competition, IPR protection and corruption, which would help re-branding of Russia as a safe and attractive investment location. Also a number of countries such as Finland, Ireland, Netherlands, Denmark, Estonia, Slovakia, Slovenia and Sweden are expected to see their welfare increase by around 0.5% of GDP.free trade agreement, WTO accession, European Union, Russian Federation, labor market, environment, NTBs, CGE

    An estimate of the terrestrial carbon budget of Russia using inventory-based, eddy covariance and inversion methods

    We determine the carbon balance of Russia, including Ukraine, Belarus and Kazakhstan using inventory based, eddy covariance, Dynamic Global Vegetation Models (DGVM), and inversion methods. Our current best estimate of the net biosphere to atmosphere flux is -0.66 Pg C yr-1. This sink is primarily caused by forests that using two independent methods are estimated to take up -0.69 Pg C yr-1. Using inverse models yields an average net biosphere to atmosphere flux of the same value with a interannual variability of 35%. The total estimated biosphere to atmosphere flux from eddy covariance observations over a limited number of sites amounts to -1 Pg C yr-1. Fires emit 137 to 121 Tg C yr-1 using two different methods. The interannual variability of fire emissions is large, up to a factor 0.5 to 3. Smaller fluxes to the ocean and inland lakes, trade are also accounted for. Our best estimate for the Russian net biosphere to atmosphere flux then amounts to -659 Tg C yr-1 as the average of the inverse models of -653 Tg C yr-1, bottom up -563 Tg C yr-1 and the independent landscape approach of -761 Tg C yr-1. These three methods agree well within their error bounds, so there is good consistency between bottom up and top down methods. The best estimate of the net land to atmosphere flux, including the fossil fuel emissions is -145 to -73 Tg C yr-1. Estimated methane emissions vary considerably with one inventory-based estimate providing a net land to atmosphere flux of 12.6 Tg C-CH4yr-1 and an independent model estimate for the boreal and Arctic zones of Eurasia of 27.6 Tg C-CH4yr-1

    The Nature, Causes, Effects and Mitigation of Climate Change on the Environment

    Get PDF
    This book examines global warming and climate change over the past five decades in mainly subtropical and tropical countries. The amount and types of changes in these countries vary with the environment but are often less than those occurring in the Arctic and northern countries. Chapters address such topics as the controversy surrounding global warming, the effects of climate change on agriculture, changes in land use and hydrology, and more
