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 ...

Industrial and Environmental Policies: Reciprocal Impacts

Total as a key player of the Oil and Gas industry is providing answers to 25 environmental challenges. In that respect, it has already developed environmental objectives and policies. Its environmental footprints is being assessed, controlled and reduced with a set of concrete means to improve its performance, a better selection of major challenges and a better report to external stake holders. Energy and climate issues are inextricably interwoven, which means that we have to help to reconcile the objectives of today’s society, pursuing economic growth while protecting the climate for future generations. Faced with this predicament, we are ...

Debate

The European Science Foundation (ESF) and the French Foundation of the Maison des Sciences de l’Homme (FMSH) (within the Entre-Sciences programme) have agreed to jointly develop a new conference series in environmental sciences; an effort to actively foster exchanges between scientists working in the humanities and social sciences and their colleagues in the life and natural sciences. This interdisciplinary conference present the new advances in the modelling of the Global Change that combines Geosciences and Economics, with a perspective view from history - given the novelty of their interrelations – and from political science – given the impact of 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 ...

The Economics of the Climate/Development of the Gordian Knot; Beyond a Sound Pessimism

We will first suggest that costs of meeting ambitious climate targets capable to stabilize global warming below 2°C or 3°C temperature increase have been underestimated so far. The first reason is the underestimation of baseline emission scenarios, the second is the magnitude of transition costs towards a low carbon development profile in emerging economies. Second we will show that this pessimistic diagnosis does not lead to inaction but to a reframing of discussions on future international coordination of climate action. We will insist on the necessity of complementing the conventional approaches relying on the emergence of a world carbon price ...
