The Largest Lakes and reservoirs of Russia as a Priority Water Ressource for Society

Global change for the last 25 years drives to important changes in hydrometeorological regime in different regions, reflecting water resources change of the larges reservoirs and lakes of Russia and of lakes’ district with more than 460,000 small and middle size lakes (North-western part of Russia and Finland. Interdisciplinary approaches in water resources research include as methods of traditional hydrology and climatology as paleoclimatology and economy. Decrease in the water level of largest Lakes (Ladoga, Onega, Ilmen) by 35-70 cm has been registered over the 1990s, the warmest decade in the time series. At the same time inflow to the ...

Turning Hazards into Ressources? Climate Change, Floods and Coastal Wetlands in the Costa Brava (North-East Iberian Peninsula)

According to the IPCC Fourth Assessment, one of the most vulnerable areas in Europe are coastal zones. This is due to sea level rise combined with increased risks from storms. Coastal wetlands, in particular, are projected to be negatively affected by sea-level rise especially where they are constrained on their landward side, and lack sediment supply. Approximately 20 percent of existing coastal wetlands may disappear by 2080 because of the expansion of the sea. Mediterranean low-lying sedimentary coasts with highly diverse ecosystems appear to be the most vulnerable areas to this phenomenon. The 4th IPCC Report also warns about the ...

Social Impact of global Environmental Change on Farming Communities on the Ogoli River Bank in Otukpo Area of Benue State, Nigeria

One of the manifestations of the global change in this study area is a marked reduction in the duration and amount of rainfall. This adversely affects the volume of the head waters that ultimately determine the volume of the Ogoli River which is used for irrigation. Consequently, food security and livelihood of the farming communities whose mode of agricultural production is rain-fed is adversely affected. Using Participatory Learning Action (PLA) technique involving three distinct groups of adult male, adult female and youth, the study seek to evaluate the coping mechanisms of these vulnerable group to draught and reduced volume of ...

The Effect of Thermal Pollution on Benthic Foraminiferal Assemblages, in the Mediterranean Shore Face Adjacent to Hadera Power Plant (Israël)

Over the past several decades public and scientific awareness to global warming has increased significantly. As a result, many studies have examined the affects of global warming. However, the consequences of global warming on marine living organisms at the Levantine basin of the East Mediterranean has not yet been explored. In this study, we have used the thermal pollution of a power plant at the Mediterranean coast of Israel as an analog for the expected future trend of sea surface temperature (SST) rise. We have performed a sequence of 11 sampling campaigns at 5 stations located along a temperature gradient ...

Present-Day Geomorphological Changes in Polar Regions

The landscape uniqueness of polar zone manifests itself in morphological traces of older glaciations and marine transgressions, areas of present-day glaciations, multi-year permafrost, multi-year snow covers, deglaciation processes variable in time and space and resulting in an expansion of ice-free 94 areas, multi-directional geosuccession, and finally in the various responses of the Arctic peoples to landscape changes and the growing human impact. The abrupt landscape changes taking place over a period shorter than the life span of a single generation can be due to a wide variety of natural causes, whether endogenous or exogenous, or to the increasing, multi-directed human ...

Interlocking Natural and Social Systems - Resilience, Governance and Research Policy Considerations

In this presentation the start is made from the 2007 IPCC statement that it now seems consolidated that there is a clear sign of the importance of the anthropogenic factors in the climate change panorama in addition to the natural phenomena. Thus the current situation of civilisation seems to be characterised by the quickly growing interference and to some extent control by humans over natural flows e.g. the carbon or nitrogen cycles to an extent not earlier seen in history. This development is of recent date - maybe half a century - and could be regarded as the beginning of ...

Post-2012 options to Reduce Greenhouse Gas Emissions

The presentation will focus on post-2012 options to reduce greenhouse gas (GHG) emissions, putting special emphasis on the need to abate world emissions. The presentation will focus on post-2012 options to reduce greenhouse 27 gas (GHG) emissions, putting special emphasis on the need to abate world emissions at least cost, which in turn requires the need to select a least-cost set of policy instruments. In particular, model simulations will be presented to discuss whether and how price instruments should be combined with technology- support policies in order to reduce overall mitigation costs. On a more speculative note, the potential implications ...

The Sustainability of Kyoto's Architecture: Where Did the Victims of Climate Change Go?

cept of “expropriation” in the case of territories exposed to a rise in sea levels. The premise of my project is that although future generations in all countries will be affected by climate change, the inhabitants of poor countries and small island states will be especially hard hit in less than 30 years; however, their situation has been neglected by the current international regime. This neglect can be demonstrated and explained using approaches from political science (mainly policy analysis and the Advocacy Coalition Framework by Sabatier), which says that the decisions behind privileged tradable pollution rights and the valuation of ...

Carbon Offsetting: An Ethical and Psychological Approach

The carbon offset market is becoming more and more popular. However, 57 until now few studies have attempted to approach the phenomenon from a social sciences’ perspective. By distinguishing three levels of analysis – the technical, psychological and ethical aspects – this work has a double objective: to better understand the mechanisms underlying the offsetting phenomenon and to evaluate its effectiveness as a greenhouse gas emissions mitigation tool. The comments made about the system concern the voluntary carbon offset market mostly, with a special focus put on its application in developing countries. Some observations however are valid for the Clean ...
