This work becomes with methodological rigor a part of the innovative proposals for the characterization of the areas at risk of desertification. The complexity of the phenomenon of desertification, which involves extended surfaces in all continents, is one of the most alarming processes of the environmental degradation of our Planet and threatens the health and the living conditions of over a billion of persons. The food crisis, in continuous increase, ask for the world of research to urgently supply reassuring solutions concerning the acquisition of indicators, which are easy to monitor and concur to control the phenomenon in order to fight its acceleration. The constant but different combination that determines the diffusion of deserti- cation in the territories, attributable mostly to climatic changes and the activities of the man, makes our job challenging and complicated, since it varies from region to region. We are aware of all this and therefore we think that the methodological approach of survey of the data is an extremely important element to locate of the phenomenon and to monitor its course. This work, which is characterized for its multi-disciplinary approach, suggests solutions that we wish will quickly find concrete applications at international level.

There is a low but uncertain probability that climate change could trigger "mega-catastrophes," severe and at least partly irreversible adverse effects across broad regions. This paper first discusses the state of current knowledge and the defining characteristics of potential climate change mega-catastrophes. While some of these characteristics present difficulties for using standard rational choice methods to evaluate response options, there is still a need to balance the benefits and costs of different possible responses with appropriate attention to the uncertainties. To that end, the authors present a qualitative analysis of three options for mitigating the risk of climate mega-catastrophes - drastic abatement of greenhouse gas emissions, development and implementation of geoengineering, and large-scale ex ante adaptation - against the criteria of efficacy, cost, robustness, and flexibility. They discuss the composition of a sound portfolio of initial investments in reducing the risk of climate change mega-catastrophes.

Based on the suggestions made by the speakers of Plenary Session IV “Challenges to the management of water resources and to countering desertification in the Mediterranean region” during the 15th Economic and Environmental Forum, the OCEEA proposed to organize a workshop on “Water Scarcity, Land Degradation and Desertification in the Mediterranean region – Environment and Security Aspects”. In order to build on common synergies, OSCE sought co-operation with c- leagues from NATO, in particular from the Science for Peace and Security Programme. NATO has a longstanding expertise on the issue and had organised in Valencia, in December 2003, a NATO scientific workshop on “Desertification and Security in the Mediterranean Region”. The objective of the new proposed wo- shop would be to broaden its focus from the scientific community to include also policy makers. 1 The workshop, aimed at government of cials from the Mediterranean Region, gathered representatives of Water management, Land degradation and Desert- cation Departments of Ministries of Environment and representatives from the Ministries of Foreign Affairs. In addition, policy makers, scientists and experts were also invited. The aim was to discuss how the OSCE, NATO and other competent organizations like the UNCCD, UNEP, MAP, and the EU could play a role in ensuring that environment and security linkages in terms of water scarcity, land degradation and desertification are addressed in the Mediterranean Region.
