Challenging the conventional wisdom that French environmentalism can be dated only to the post-1945 period, Caroline Ford argues that a broadly shared environmental consciousness emerged in France much earlier. Natural Interests unearths the distinctive features of French environmentalism, in which a large and varied cast of social actors played a role. Besides scientific advances and colonial expansion, nostalgia for a vanishing pastoral countryside and anxiety over the pressing dangers of environmental degradation were important factors in the success of this movement. Over the nineteenth and twentieth centuries, war, political upheaval, and natural disasters—especially the devastating floods of 1856 and 1910 in Paris—caused growing worry over the damage wrought by deforestation, urbanization, and industrialization. The natural world took on new value for France’s urban bourgeoisie, as both a site of aesthetic longing and a destination for tourism. Not only naturalists and scientists but politicians, engineers, writers, and painters took up environmental causes. Imperialism and international dialogue were also instrumental in shaping environmental consciousness, as the unfamiliar climates of France’s overseas possessions changed perceptions of the natural world and influenced conservationist policies. By the early twentieth century, France had adopted innovative environmental legislation, created national and urban parks and nature reserves, and called for international cooperation on environmental questions.
Nothing could seem more contemporary than climate change. Yet, in Chaos in the Heavens, Jean-Baptiste Fressoz and Fabien Locher show that we have been thinking about and debating the consequences of our actions upon the environment for centuries. The subject was raised wherever history accelerated: by the conquistadors in the New World, by the French revolutionaries of 1789, by the scientists and politicians of the nineteenth century, by the European imperialists in Asia and Africa until the Second World War. Climate change was at the heart of fundamental debates about colonisation, God, the state, nature, and capitalism. From these intellectual and political battles emerged key concepts of contemporary environmental science and policy. For a brief interlude, science and industry instilled in us the reassuring illusion of an impassive climate. But, in the age of global warming, we must, once again, confront the chaos in the heavens.
Mobilities Facing Hydrometeorological Extreme Events 1: Defining the Relevant Scales of Analysis provides a summary of the interdisciplinary work done over the past ten years on the exposure of daily mobility. Residential mobility, the way in which the occupation of the flood zones evolves with time, and the resulting immobile exposure are also at the heart of this work. In the face of recrudescence and the intensification of fast floods, the book seeks to understand how the interaction of hydro-meteorological, social and development dynamics combine to bring about an improvement or, on the contrary, a worsening of both mobile and immobile exposure. The book relies on different fields and studies conducted in the South East of France and more broadly on the Mediterranean basin to answer these questions and verify these hypotheses, with a forward challenge to better understand how population movements are exposed to these phenomena. - Provides a synthesis of interdisciplinary work on the exposure of daily mobilities - Establishes a diagram of the evolution of the flood zones and the immobile exposure - Finds the cause and effect of these phenomena - Conducts studies to answer these questions and verify these hypotheses
The author has been conscious for several years of the problems of flooding, erosion, and other natural constraints in the Delta. These are his experiences, his knowledge of the coastal Niger Delta region. His MPhil and PhD research were on these problems. Above all, he was born and grew up in the delta, which gave him the determination to find solutions to the problems that have been giving the authorities the excuse to neglect the region, since its independence in 1960. The influence that these scourges exercise on the region is as much human as the topography of the environment and the morphology of the towns. He believes that there are solutions and engaged himself in finding these solutions.
Ce manuel pratique aide à comprendre les grands principes régissant la morphologie des cours d’eau et leur dynamique pour mieux concevoir des aménagements qui sauront résister aux crues sans déséquilibrer pour autant les écosystèmes. Le chapitre 1 donne les définitions, principes de base et résultats d’hydraulique à surface libre. Les chapitres 2 à 4 approfondissent le diagnostic des rivières en tenant compte du transport solide et de la constante interaction entre l’écoulement, le fond, les berges et le champ d’inondation. Les chapitres 5 à 9 exposent les différents aménagements et entretiens pour utiliser l’eau ou se protéger des crues. Cette 2e édition, entièrement réactualisée et augmentée de nombreux schémas et photos, aborde de nouveaux points : les calculs hydrauliques des déversoirs latéraux, des estimations de débit solide adaptées aux fortes pentes, la morphologie des torrents et les conséquences morphologiques des barrages, la restauration morphologique des rivières, les processus d’érosion par surverse, la conception des zones d’expansion de crues, des procédés de protection de berge ou de traitement des digues, la nouvelle norme sur les enrochements, etc... Diagnostic, aménagement et gestion des rivières s’adresse aux professionnels en charge de la gestion et de l’aménagement des cours d’eau ou de la police de l’eau : cabinets d’ingénierie, collectivités territoriales, établissements publics, sociétés d’aménagement régional et services déconcentrés et centraux de l’État. Il sera une aide précieuse pour les étudiants en écoles d’ingénieur ou en université et intéressera les chercheurs en mécanique des fluides, géomorphologie ou écologie fluviale.
