A la hausse constante des prix alimentaires s'ajoutent les effets de plus en plus dramatiques du changement climatique et un monde de plus en plus instable. Serons-nous réellement capables de nourrir une population qui devrait bientôt atteindre 10 milliards. Le professeur Tim Benton, l’un des plus grands experts mondiaux des systèmes alimentaires, estime que notre modèle économique de croissance infinie sur une planète aux ressources finies est voué à s’effondrer. Mais quand cela se produira-t-il ? Qu’est-ce que cela signifie concrètement ? Et enfin, entrons-nous réellement dans une ère de famine ?

Tim Benton, expert reconnu en sécurité alimentaire mondiale, afin de comprendre les causes de l'effondrement de nos systèmes alimentaires et les conditions nécessaires à la construction d'un système véritablement régénérateur. – Pourquoi le système alimentaire actuel est fondamentalement insoutenable – Que signifie concrètement le concept de « limites planétaires » – Le mythe de la croissance verte – Comment nos régimes alimentaires et nos systèmes agricoles doivent évoluer – Les 3 mécanismes qui nous empêchent d'avancer

One of the biggest upheavals in a millennium is on its way, strengthened by the climate crisis. We need leaders who make things better not worse

Climate models simulate a wide range of 21st century warming for a given forcing scenario. Constraining this uncertainty is a central challenge in climate science because of its implications for climate policy and adaptation. The Transient Climate Response (TCR) is a key idealized metric used to quantify future warming in response to an exponentially increasing CO2 concentration. Climate models span a range of 1.3–3 K for TCR. In attempts to constrain this range, emergent constraints on TCR based on historical temperature trends consistently pointed towards TCR values at the lower end of the range of models. However, recent evidence from trends in the short-wave and long-wave components of Earth's energy imbalance (EEI) at the top-of-atmosphere suggests that models with higher TCR lie closer to the observed EEI trends. Here, we reconcile this discrepancy and provide a revised range for TCR of 1.9–2.6 K. Using a statistical variability-filtering approach, we show that previous temperature-based constraints we

In 1999, two colonels in China’s People’s Liberation Army wrote a strategy piece called Unrestricted Warfare. It gives guidance on how China can defeat the United States and the West in general. The 228 pages are a surprisingly easy and entertaining read. They’re also illuminating.

The concepts of Green Growth and Degrowth represent two major narratives in the public and academic debate on socio-ecological transformation. . . Using a comparative analysis of the two research fields, we confirm several findings from previous reviews, including that Green Growth research is highly policy oriented, focuses on practical implementation and builds on empirical research methods, while Degrowth research is highly theory-driven, focuses on the analysis of complex human-nature interrelationships and builds on a sound theoretical and conceptual foundation. Our analysis further reveals that Green Growth and Degrowth are two rather isolated fields of research with little exchange and mutual reference on related topics. However, the topic of social change and transition represents an intersecting and promising future research area. . . .

Whether you’re looking for hands-on strategies, a deeper understanding of the big-picture frameworks underpinning those strategies, or thought-provoking reflections on the current state of the world and its likely future, this book has something for you.
