The Intergenerational Equity: A Concept to Build for Sustainability, the Case of Global Warning

Defined as “the relation that each generation has with the last or future generations in the use... of the natural or cultural resources of planet”, Intergeneration equity (here I.E) imposes rules of optimal use of these resources on each generation. But it still remains a vague concept which needs a clear definition and poses some philosophical problems. Its emergence in right of the environment followed the scientific awakening on the ecological threats, in the years 1960 and led to a greater implication of the United Nations to coordinate international actions in environment field. The conferences of Stockholm in 1972 and ...

The Costs of Strategic Adaptation in a Simple Conceptual of Climate Change

A simple theoretical model of the process of strategic adaptation to climate change is proposed. Climate change is represented by a non-stationary Markov process on the space of climate states, and strategic adaptation by a simple resource allocation task in which agents incur costs when moving resources from one activity to another. A stationary analysis allows diagnostics that quantify the net costs of climate change, and the long-run benefits to adaptation, to be defined. A full dynamic analysis of the model 74 allows for the computation of the costs of negotiating the transition between two stationary climate regimes. We analyze ...

Climatic Hazard Mitigation Through Risk and Resilience Committees in Nepal

Nepal lies in an ecologically fragile and seismic region with a history of devastating Glacier Lake Outburst Flood (GLOF), landslides and earthquakes. Increases in temperature could increase the frequency and magnitude of climatic disaster occurrences. Winter snow in Kathmandu in 2007 after nearly 65 years absence, frequent flood events since 2000, and an increased number of glacier lakes in the upper Himalayas indicates that climate change may already be having a significant impact. Disaster events in Nepal are known to impact disproportionately on poor and marginalised people who live in more exposed environments during risky times and without adequate forms ...

Climate Models: learning from the Past Long-Term Climate Variability

Projections of future climate change rely on global climate models. Such models simulate the dynamics and physics of the coupled atmosphere-ocean system and move towards models of the full Earth system. These models are evaluated on the present day mean climate as well as on climate variability over the last century. Although climate models agree on the overall patterns of future climate change, discrepancies are still displayed between models, both in amplitude and at the regional scale (e.g., IPCC AR5 (2007)). Past climates offer an unique opportunity to evaluate climate models on climate conditions different from the present-day conditions ...
