Book Description
L’énergie est le moteur de la croissance mondiale depuis la révolution industrielle. Alors que notre consommation énergétique augmente continûment, ce livre nous explique que l’énergie va manquer bien plus vite qu’annoncé par certains économistes, hommes politiques ou pétroliers. Selon de nombreux experts géologues et pétroliers indépendants, le pic de production du pétrole semble être désormais atteint et celui charbon pourrait l’être pour 2030-2050. De nombreuses ressources minérales (comme le cuivre) pourraient également venir à manquer. L’ouvrage tente de prévoir quelles seront les conséquences de ces pénuries. Pour nos sociétés, c’est un sacré défi à relever, avec la diminution de la consommation d’énergie et le développement d’énergies renouvelables. Pour le climat, l’épuisement des combustibles fossiles est une chance : le réchauffement étant largement dû au gaz carbonique issu des combustibles fossiles, leur pénurie va probablement cantonner la hausse des températures à une valeur inférieure à 2°C en 2100.

Book Description
+ 6°C en 2100 ? Voilà l'avenir sombre que certains scénarios envisagent aujourd'hui. Seulement voilà, le carburant du réchauffement climatique va manquer bien plus vite qu'annoncé : selon de nombreux experts géologues et pétroliers indépendants, le pic de production du pétrole semble être désormais atteint et ceux du gaz et du charbon devraient l'être avant 2030-2050. Or ces combustibles fossiles sont notre principale source d'énergie et le pétrole est le premier responsable de la folle croissance observée depuis l'après-guerre. La pénurie des combustibles fossiles provoquera donc une crise énergétique et économique sévère, avec à la clé de sacrés défis à relever, comme apprendre le sevrage énergétique et développer les énergies renouvelables. Pour le climat en revanche, la pénurie des combustibles fossiles est une chance : elle va probablement cantonner la hausse des température à une valeur inférieure à 2°C en 2100.

Book Description
Crise climatique, crise pétrolière, crise de l’eau, crise alimentaire : le XXIe siècle est mal parti. Le climat se détériore sous l’action de l’homme et les ressources naturelles s’épuisent, tandis que la demande ne fait que croître sous le double effet de la croissance démographique et économique. Pire encore, les tensions se conjuguent, l’aggravation des unes empire les autres, sur fond de crise financière. Tous les voyants sont au rouge : la panne sèche est imminente. Un immense défi est lancé à tous les pays, développés et en développement. Il faut d’urgence trouver des solutions, sans quoi notre civilisation pourrait être menacée. L’utilisation raisonnée de la technologie, mais aussi la réduction de la pauvreté et des inégalités ainsi que l’éducation sont essentielles à cet égard. Catherine Gautier et Jean-Louis Fellous examinent les inter-connexions entre l’énergie, l’eau, l’alimentation à l’heure du changement climatique et explorent les alternatives possibles. Ils tentent aussi de mobiliser les consciences : chaque être humain doit participer aux décisions complexes qui engagent l’avenir de l’humanité. Catherine Gautier est professeur de géographie physique à l’Université de Californie à Santa Barbara et a dirigé l’Institute for Computational Earth System Science. Jean-Louis Fellous est directeur du Comité mondial de recherche spatiale et a publié Avis de tempête. Ils ont dirigé l’ouvrage collectif Comprendre le changement climatique.

Book Description
After fifteen years of reconstruction in a relatively peaceful environment spanning the years 1990 to 2004, Lebanon has experienced successive violent political events resulting from complex entangled internal and external struggles. The Syrian crisis and its political, economic and demographic consequences on Lebanon have increased these tensions. This atlas sheds light on these new challenges and adds new data that complete the analyses already published in the Atlas du Liban. Territoires et société (Atlas of Lebanon. Territories and Society) released in 2007 by the same research team. Some of its components are included in this edition. Beyond the international regional crisis and the population movements, it takes into account Lebanon’s socio-economic dimensions, the environmental issues linked to uncontrolled urbanization and to natural risks, as well as conflicts due to local territorial management. This atlas is the result of a collaborative endeavor between French and Lebanese researchers. It uses a geographical approach that puts in the foreground a spatial analysis of social and natural phenomena. Public sources are scarce in Lebanon, especially at the local scale. They are sometimes less reliable and difficult to access. It is particularly the case for the Lebanese census data, conversely data are abundantly available on the refugees population, which is less known than the population of refugees. International data help compare Lebanon to its neighbors. Thematic data produced by some ministries are helpful to provide a detailed view regarding specific domains. Analyses processed on aerial and satellite images have produced essential data on urbanization and environment. Local thematic fieldwork surveys have provided additional data. The book consists of seven chapters. The first one deals with the territorial state-building seen in the light of regional geopolitics, and emphasizes internal violence and the reemergence of militias and armed groups that fight each other and the state army. Lebanon is once again perceived as a territory divided between multiple allegiances. The second chapter is devoted to the analysis of population dynamics, despite the lack of reliable data whose sources are subject to discussion. It includes analyses of internal population flows, the Lebanese diaspora, and the assessment of Syrian refugees’ influx. The third chapter shows the fragility of the Lebanese economic model. Its dependency on foreign investments and on...

Book Description
"Your Mindful Compass" takes us behind the emotional curtain to see the mechanisms regulating individuals in social systems. There is great comfort and wisdom in knowing we can increase our awareness to manage the swift and ancient mechanisms of social control. We can gain greater flexibility by seeing how social controls work in systems from ants to humans. To be less controlled by others, we learn how emotional systems influence our relationship-oriented brain. People want to know what goes on in families that give rise to amazing leaders and/or terrorists. For the first time in history we can understand the systems in which we live. The social sciences have been accumulating knowledge since the early fifties as to how we are regulated by others. S. Milgram, S. Ashe, P. Zimbardo and J. Calhoun, detail the vulnerability to being duped and deceived and the difficulty of cooperating when values differ. Murray Bowen, M.D., the first researcher to observe several live-in families, for up to three years, at the National Institute of Mental Health. Describing how family members overly influence one another and distribute stress unevenly, Bowen described both how symptoms and family leaders emerge in highly stressed families. Our brain is not organized to automatically perceive that each family has an emotional system, fine-tuned by evolution and "valuing" its survival as a whole, as much as the survival of any individual. It is easier to see this emotional system function in ants or mice but not in humans. The emotional system is organized to snooker us humans: encouraging us to take sides, run away from others, to pressure others, to get sick, to blame others, and to have great difficulty in seeing our part in problems. It is hard to see that we become anxious, stressed out and even that we are difficult to deal with. But "thinking systems" can open the doors of perception, allowing us to experience the world in a different way. This book offers both coaching ideas and stories from leaders as to strategies to break out from social control by de-triangling, using paradoxes, reversals and other types of interruptions of highly linked emotional processes. Time is needed to think clearly about the automatic nature of the two against one triangle. Time and experience is required as we learn strategies to put two people together and get self outside the control of the system. In addition, it takes time to clarify and define one's principles, to know what "I" will or will not do and to be able to take a stand with others with whom we are very involved. The good news is that systems' thinking is possible for anyone. It is always possible for an individual to understand feelings and to integrate them with their more rational brains. In so doing, an individual increases his or her ability to communicate despite misunderstandings or even rejection from important others. The effort involved in creating your Mindful Compass enables us to perceive the relationship system without experiencing it's threats. The four points on the Mindful Compass are: 1) Action for Self, 2) Resistance to Forward Progress, 3) Knowledge of Social Systems and the 4) The Ability to Stand Alone. Each gives us a view of the process one enters when making an effort to define a self and build an emotional backbone. It is not easy to find our way through the social jungle. The ability to know emotional systems well enough to take a position for self and to become more differentiated is part of the natural way humans cope with pressure. Now people can use available knowledge to build an emotional backbone, by thoughtfully altering their part in the relationship system. No one knows how far one can go by making an effort to be more of a self-defined individual in relationships to others. Through increasing emotional maturity, we can find greater individual freedom at the same time that we increase our ability to cooperate and to be close to others.

Book Description
The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.
