The seaweed revolution is a fresh hope for tomorrow.Seaweed develops in water everywhere, from the eternal glaciers to lagoons heated by the sun, from seas saturated with salt to the fresh water of our rivers. Yet we only know how to cultivate a few dozen varieties, at most. Incredibly diverse, seaweed could help to bring back balance in our ecosystems through a wide range of applications. It could allow us to better feed human beings and animals, replace plastic and fertilizers, boost medical innovations, mitigate global warming, repair biodiversity and support economies in coastal communities where fish stocks are declining.Although seaweed has supported our development for millions of years, we have lost our connection with it and focused our efforts purely on land cultivation. Today a fast-growing global population, combined with climate, social and environmental crises, gives us compelling reasons to reconsider this forgotten treasure.‘This book is a must-read for anyone who cares about our planet's future’ Mark Lynas, journalist and author of Our Final Warning: Six Degrees of Climate Emergency‘An essential read for anyone who is curious about the extraordinary powers of seaweed to change the world, ’ Alexandra Cousteau, Head of Oceans 2050, and Jacques Cousteau’s granddaughter‘Seaweeds and algae have an essential role to play in the solutions available to us and Vincent Doumeizel’s The Seaweed Revolution shows us how’ Ambassador Peter Thomson, UNSG’s Special Envoy for the Ocean and former President of the UN General Assembly‘Seaweed holds the key to help solve many of the crises the world is facing’ Carlos M. Duarte, Executive Director of the Coral Research and Development Accelerator Platform‘A powerful read which will enlighten, enthuse and inspire in equal measure’ Ocean Challenge Magazine'The potential of seaweed, or marine algae, to transform our world is huge… excellent book' New ScientistVincent Doumeizel is Senior Adviser on the oceans to the United Nations Global Compact as well as director of the Food Programme at the Lloyd’s Register Foundation.

“The Earth is a mosque.” Muslims are compelled by their religion to praise the Creator and to care for their community. But what is not widely known is that there are deep and long-standing connections between Islamic teachings and environmentalism. In this groundbreaking book, Ibrahim Abdul-Matin draws on research, scripture, and interviews with Muslim Americans to trace Islam’s preoccupation with humankind’s collective role as stewards of the Earth. Abdul-Matin points out that the Prophet Muhammad declared that “the Earth is a mosque.” Deen means “path” or “way” in Arabic. Abdul-Matin offers dozens of examples of how Muslims can follow, and already are following, a Green Deen in four areas: “waste, watts (energy), water, and food.” At last, people of all beliefs can appreciate the gifts and contributions that Islam and Muslims bring to the environmental movement. “Ibrahim Abdul-Matin not only shows the myriad ways American Muslims are contributing to the resolution of the environmental crisis that threatens us all but also goes a long way toward humanizing the Muslim community by sharing with the reader the lives of so many extraordinary, talented, and visionary people.” —Imam Zaid Shakir, Zaytuna College, Berkeley, California. “Ibrahim blends his passion for a green economy, his love and understanding of faith, and a deep commitment to justice in this book.” —Van Jones, founder, Green for All. “At a moment when distortions of Islam are what feed most Americans, Ibrahim Abdul-Matin has done something both practical and inspiring. He persuades us that the imperiled environment is both common struggle and common ground for people who share, it turns out, more than simply God.” —John Hockenberry, Emmy-award-winning journalist, author of Moving Violations, and host of National Public Radio’s The Takeaway.

Comment et à quel point la biodiversité – végétale et animale – peut-elle nous permettre de lutter contre le réchauffement climatique ? C’est le sujet inédit de ce livre qui met en avant le rôle décisif joué par les grands puits de carbone naturels : océans, forêts, sols agricoles, mais aussi zones humides, prairies et permafrost. S’appuyant sur les recherches scientifiques les plus récentes, l’auteur nous dévoile le fonctionnement incroyablement sophistiqué de ces écosystèmes et leur potentiel de captation du carbone. Il montre comment les espèces de planctons, de poissons, de baleines, de requins, d’oiseaux marins… jouent un rôle clé dans la « pompe à carbone biologique » océanique ; comment la microfaune, les champignons et les animaux font de nos forêts, prairies, cultures agroécologiques… de grands régulateurs du cycle du carbone comme du cycle de l’eau. Protéger ces puits naturels, les renforcer et les reproduire, c’est la voie du géomimétisme – le biomimétisme au service du climat. Une voie négligée jusque-là, et pourtant fondamentale pour soigner le climat, au même titre que la transition énergétique. Un éloge du génie du vivant et un antidote à l’écoanxiété ! Pierre Gilbert est prospectiviste spécialisé sur les sujets environnementaux et climatiques. C’est à ce titre qu’il a cofondé l’Institut Rousseau puis Sator, une plateforme de masterclass vidéo novatrice faisant appel aux meilleurs experts de leurs sujets. Vulgarisateur hors pair, conférencier et entrepreneur, il est l’auteur d’un premier livre sur le géomimétisme. Préface de Marc-André Selosse, professeur du Muséum national d’histoire naturelle et à l’Institut universitaire de France, président de la Fédération BioGée.

En 1540, Hans Stolz, vigneron à Guebwiller, décrit le climat, évoquant une chaleur torride et une pénurie d’eau sans précédent qui frappe le pays. Les moulins sont à l’arrêt et de nombreux bovins meurent de soif. De plus, le ciel est obscurci par la fumée des multiples feux de forêts. Un grand nombre de chroniqueurs décrivent cette année de sécheresse, la pire en Europe depuis 1500. De tels récits, complétés par des observations quotidiennes et des mesures à l’aide d’instruments pour les périodes postérieures, ont contribué à la reconstitution des températures saisonnières depuis l’an mille ; un travail pionnier qui a donné lieu à la création de données statistiques auxquelles ont participé les deux auteurs de cet ouvrage.Avec les résultats de ces recherches, Christian Pfister et Heinz Wanner ont pu reconstituer, pour la première fois, l’histoire du climat saisonnier en Europe. Les analyses montrent qu’avant 1900, les hivers froids dominaient, tandis que les étés étaient plutôt équilibrés. Avant l’influence de l’effet de serre d’origine humaine, les fluctuations étaient surtout liées à des modifications de l’orbite terrestre, à l’activité solaire et à des éruptions volcaniques.L’ouvrage alterne entre explications et récits qui illustrent la manière dont la population a vécu et a fait face à des événements tels que la sécheresse millénaire de 1473, la chute brutale des températures de 1709, les voyages de découverte du Nouveau Monde par les Vikings, l’apparition des loups à Paris, les persécutions de sorcières au xvıe siècle dues au climat, et la famine déclenchée en Europe par l’éruption du volcan indonésien Tambora en 1815. Le chapitre final souligne les causes de l’état d’urgence climatique actuel et propose une projection vers l’avenir.Grâce à son langage accessible et à son illustration convaincante, ce livre répond à la fois aux besoins des spécialistes et du grand public.

Eagles have fascinated humans for millennia. For some, the glimpse of a distant eagle instantly becomes a treasured lifelong memory. Others may never encounter a wild eagle in their lifetime. This book was written by people who have dedicated years to the study of eagles, to provide an insider''s view for all readers, but especially those who have never been up close and personal with these magnificent yet often misunderstood creatures. In their stories, twenty-nine leading eagle researchers share their remarkable field experiences, providing personal narratives that don''t feature in their scientific publications. They tell of their fear at being stalked by grizzly bears, their surprise at being followed by the secret police, their embarrassment when accidentally firing mortar rockets over a school gymnasium, and their sense of awe at tracking eagles via satellite. The reader experiences the cultural shock of being guest of honor at a circumcision ceremony, the absurdity of sharing an aquatic car with the Khmer Rouge, and the sense of foreboding at being press-ganged into a frenzied tribal death march through the jungle. The Eagle Watchers covers twenty-four species on six continents, from well known (bald eagle; golden eagle), to obscure (black-and-chestnut eagle; New Guinea harpy eagle), and from common (African fish eagle) to critically endangered (Philippine eagle; Madagascar fish eagle). The diverse experiences vividly described in this book reveal the passion, dedication, and sense of adventure shared by those who study these majestic birds and strive for their conservation. Featuring stunning color photographs of the eagles, information on raptor conservation, a global list of all eagle species with ranges and conservation status, and a color map of the sites visited in the book, The Eagle Watchers will appeal to birders, conservationists, and adventure travelers alike. To further support the conservation programs described in this book, all royalties are being donated to two leading nonprofit organizations for raptor conservation training and fieldwork: Hawk Mountain Sanctuary Intern Program and the National Birds of Prey Trust.

The results presented in this book summarize the main findings of the CARBOFOR project, which brought together 52 scientists from 14 research units to investigate the effects of future climate on the carbon cycle, the productivity and vulnerability of French forests. This book explains the current forest carbon cycle in temperate and Mediterranean climates, including the dynamics of soil carbon and the total carbon stock of French forests, based on forest inventories. It reviews and illustrates the main ground-based methods for estimating carbon stocks in tree biomass. Spatial variations in projected climate change over metropolitan France throughout the 21st century are described. The book then goes on to consider the impacts of climate change on tree phenology and forest carbon balance, evapotranspiration and production as well as their first order interaction with forest management alternatives. The impact of climate change on forest vulnerability is analysed. A similar simulation study was carried out for a range of pathogenic fungi, emphasizing the importance of both warming and precipitation changes. The consequences of climate change on the occurrence of forest fires and the forest carbon cycle in the Mediterranean zone are also considered.A valuable reference for researchers and academics, forest engineers and managers, and graduate level students in forest ecology, ecological modelling and forestry.
