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 ...

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 Intergovernmental Panel on Climate Change and the Challenges of Climate policy, Equity and Ethics

The 2007 Intergovernmental Panel on Climate Change (IPCC) report provides clear guidance for the greenhouse gas emissions reductions needed to limit global warming to specific targets such as 2 °C above pre-industrial values, as adopted formally by the European Union. Despite the strong scientific consensus found by the IPCC concerning the reality and seriousness of global warming, worldwide emissions of the greenhouse gases that cause climate change continue to increase each year. The nations of the world are still far from agreement on how to act to reduce emissions.

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 ...

Recording Time, the Movement of sound in the City / Lisa Robertson

Recording Time : the Movement of sound in the City / Lisa Robertson. In L'Art de la Ville / The Art of the City, colloque international organisé par l'équipe Culture Anglo-Saxonne (CAS) de l'Université de Toulouse II-Le Mirail, 6-8 novembre 2008.Pour Lisa Robertson, la ville est bruit. Sur les traces du photographe Eugene Atget, elle traque les bruits de la ville, enregistre dans des clichés sonores de trente secondes leurs contours indécis et insensés, s'abandonne à leur prosodie du discontinu qui la plonge dans les fragiles vibrations d'un présent éphémère et mouvant.Extrait de la présentation générale du colloqueCe colloque s'intéressera à ...

Are European Ecosystems Vulnerable to Climate Change

The relatively simple question posed by this title turns out to be complicated in its implementation, for a number of reasons: First, ecosystems have changed in response to changing climate throughout history - however this has not normally been qualified as “vulnerability”. Second, most changes in 26 ecosystems have multiple forcings, climate change being only one of them. Third, whether changes in ecosystem functioning qualify as “vulnerability” depends largely on the human point of view. Resolving the issue is very urgent today, because it is indisputable that rapid changes are taking place and that some of these are considered “negative ...
