Integrative Paleoscience for Sustainable Management new s • • www.pages-igbp.org Vol 19 No 2 July 2011 Integrative Paleoscience for Sustainable Management Editors: John Dearing, Markus Dotterweich, Thomas Foster, Louise Newman and Lucien von Gunten The Murray-Darling River system (southeastern Australia) drains 1/7 of the Australian land- mass and is known as the "food bowl" of the nation. Due to intense water and catchment use, much of the river system and associated water bodies are now significantly environ- mentally degraded. Psyche Bend Lagoon (River Murray floodplain) shown here, was first used for significant irrigation around AD 1890. Since this time, continued catchment change (stock grazing, land clearance, irrigation) has diminished ecosystem resiliance, which, in association with confounding effects of climate change, acidified this once pristine wet- land. Paleodata demonstrates that the natural system is now outside its natural range of variability.

Increasingly, international and national reports (e.g., Millennium Ecosystem As- Highlights: Editorial Science sessment, 2005; UK National Ecosystem Assessment, 2010) highlight the need to understand how interactions between so- ciety and the environment have evolved over multi-decadal timescales to create modern landscapes. Only with the per- spective afforded by a relatively long timescale of observations can modern landscapes be effectively treated as com- plex interacting systems and analyzed for complex behavior, such as thresholds. Direct observations and measurements obtained from long-term survey or moni- toring programs are usually too short or too limited in scope to provide a compre- hensive record on their own (Fig. 1).

The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose.

  • Caspian Oil and Gas Complements Other IEA Studies of Major Supply Regions, Such As Middle East Oil and Gas and North African Oil and Gas
    3 FOREWORD The Caspian region contains some of the largest undeveloped oil and gas reserves in the world. The intense interest shown by the major international oil and gas companies testifies to its potential. Although the area is unlikely to become “another Middle East”, it could become a major oil supplier at the margin, much as the North Sea is today. As such it could help increase world energy security by diversifying global sources of supply. Development of the region’s resources still faces considerable obstacles. These include lack of export pipelines and the fact that most new pipeline proposals face routing difficulties due to security of supply considerations,transit complications and market uncertainties. There are also questions regarding ownership of resources, as well as incomplete and often contradictory investment regimes. This study is an independent review of the major issues facing oil and gas sector developments in the countries along the southern rim of the former Soviet Union that are endowed with significant petroleum resources: Azerbaijan, Kazakstan,Turkmenistan and Uzbekistan. Caspian Oil and Gas complements other IEA studies of major supply regions, such as Middle East Oil and Gas and North African Oil and Gas. It also expands on other IEA studies of the area, including Energy Policies of the Russian Federation and Energy Policies of Ukraine. The study was undertaken with the co-operation of the Energy Charter Secretariat, for which I would like to thank its Secretary General, Mr. Peter Schütterle. Robert Priddle Executive Director 5 ACKNOWLEDGEMENTS The IEA wishes to acknowledge the very helpful co-operation of the Energy Charter Secretariat, with special thanks to Marat Malataev, Temuri Japaridze, Khamidulah Shamsiev and Galina Romanova.

  • The Global Footprint of Persistent Extra-Tropical Drought in the Instrumental Era
    INTERNATIONAL JOURNAL OF CLIMATOLOGY Int. J. Climatol. (2008) Published online in Wiley InterScience (www.interscience.wiley.com) DOI: 10.1002/joc.1590 The global footprint of persistent extra-tropical drought in the instrumental era Celine Herweijer1* and Richard Seager2 1 Risk Management Solutions, London, UK 2 Lamont Doherty Earth Observatory, Columbia University, USA ABSTRACT: The major North American droughts as per instrumental records are shown to be part of a larger, global pattern of low-frequency drought variability. Drought in western North America during the 1850s–1860s, 1870s, 1890s, 1930s and 1950s, is shown to coincide with the occurrence of prolonged dry spells in parts of Europe, southern South America and western Australia. Tropical land regions are mostly wet during these periods, with the exception of central east Africa, southern India and Sri Lanka, which are dry. The recent 1998–2003 period of drought in western North America reveals a similar global hydroclimatic ‘footprint’ with the exception of a wet southern South America and continued dry conditions in the Sahel. Common to each of the six droughts is the persistence of anomalously cool east central tropical Pacific sea surface temperatures (SSTs). For the 1998–2003 case, the warming of SSTs everywhere outside of the east central tropical Pacific may be influencing precipitation and masking the influence of persistent precipitation anomalies driven from the tropical Pacific alone. In general, examination of these major historical extra-tropical droughts reveals a hemispherically and, in the extra-tropics, a zonally symmetric pattern consistent with forcing from the Tropics. Ensembles of model simulations forced by observed SSTs globally (Global Ocean Global Atmosphere, GOGA) and only within the tropical Pacific (Pacific Ocean Global Atmosphere-Mixed Layer, POGA-ML) are both able to capture the global pattern of the persistent extra-tropical drought regimes since the mid-nineteenth century.

The 14 evidence on land indicates that patterns of glaciation varied dramatically between 15 different glacial-interglacial cycles. For example, MIS (Marine Isotope Stages) 8, 10 16 and 14 are all noticeably absent from many terrestrial glacial records in North 17 America and Europe. However, globally, the patterns are more complicated with 18 major glaciations recorded in MIS 8 in Asia and in parts of the Southern Hemisphere, 19 such as Patagonia for example. This spatial variability in glaciation between glacial- 20 interglacial cycles is likely to be driven by ice volume changes in the West Antarctic 21 Ice Sheet and associated interhemispheric connections through ocean-atmosphere 22 circulatory changes. The weak global glacial imprint in some glacial-interglacial 23 cycles is related to the pattern of global ice build-up. This is caused by feedback 24 mechanisms within glacier systems themselves which partly result from long-term 25 orbital changes driven by eccentricity.

We investigate how regional differences in population aging Moscow, Russia developed over the last decade and how they are likely to evolve in the coming three decades, and we examine how demographic components of population growth contribute to the process. We use the beta-convergence approach to test whether regions are moving towards a common level of population aging. The change in population composition is decomposed into the separate effects of changes in the size of the non-working-age population and of the working-age population. The latter changes are further decomposed into the effects of cohort turnover, migration at working ages, and mortality at working ages. European Nomenclature of Territorial Units for Statistics (NUTS)-2 regions experienced notable convergence in population aging during the period 2003–2012 and are expected to experience further convergence in the coming three decades. Convergence in aging mainly depends on changes in the population structure of East-European regions. Cohort turnover plays the major role in promoting convergence.
