Book Synopsis The Routledge Handbook of Environmental History by : Emily O'Gorman
Download or read book The Routledge Handbook of Environmental History written by Emily O'Gorman and published by Taylor & Francis. This book was released on 2023-12-06 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Routledge Handbook of Environmental History presents a cutting-edge overview of the dynamic and ever-expanding field of environmental history. It addresses recent transformations in the field and responses to shifting scholarly, political, and environmental landscapes. The handbook fully and critically engages with recent exciting changes, contextualizes them within longer-term shifts in the field, and charts potential new directions for study. It focuses on five key areas: Theories and concepts related to changing considerations of social justice, including postcolonial, antiracist, and feminist approaches, and the field’s growing emphasis on multiple human voices and agencies. The roles of non-humans and the more-than-human in the telling of environmental histories, from animals and plants to insects as vectors of disease and the influences of water and ice, the changing theoretical approaches and the influence of concepts in related areas such as animal and discard studies. How changes in theories and concepts are shaping methods in environmental history and shifting approaches to traditional sources like archives and oral histories as well as experiments by practitioners with new methods and sources. Responses to a range of current complex problems, such as climate change, and how environmental historians can best help mitigate and resolve these problems. Diverse ways in which environmental historians disseminate their research within and beyond academia, including new modes of research dissemination, teaching, and engagements with stakeholders and the policy arena. This is an important resource for environmental historians, researchers and students in the related fields of political ecology, environmental studies, natural resources management and environmental planning.

Available in PDF, EPUB and Kindle. Book excerpt: Cette étude porte sur l’analyse du développement de l’irrigation dans la plaine de la Jeffara tuniso-libyenne et son incidence sur les enjeux qui entourent la gestion de la ressource en eau. Cantonnée par le passé aux oasis littorales, la pratique de l’irrigation s’est étendue, au cours des dernières décennies, aux espaces arides de la plaine, suite à la réalisation de projets publics d’aménagement hydro-agricole et au desserrement des contraintes d’acces aux nappes souterraines. Ce mouvement d’emprise agricole a engendré une profonde évolution des modes de gestion de l’eau et une dépendance croissante des systèmes de production à l’égard de l’exploitation d’aquifères aux potentialités limitées. Il participe ainsi à exacerber les risques de pénurie d’eau dans le Sud-est tunisien et en Tripolitaine occidentale. Confrontés à la multiplication des phénomènes de surexploitation des nappes souterraines, les pouvoirs publics ont mis en place un certain nombre d’arbitrages techniques, territoriaux et sectoriels en vue de sécuriser l’approvisionnement en eau des secteurs stratégiques et de contenir le processus de dégradation des ressources naturelles. Les réflexions autour du devenir de l’agriculture irriguée dans la Jeffara s’inscrivent dans le cadre d’une réorientation des politiques hydrauliques nationales et illustrent les défis que pose le problème de la rareté de l’eau dans les espaces arides. Ce travail renvoie également à une problématique plus large, relative aux mutations des espaces agropastoraux méditerranéens qui font face à des processus de désertification.
Book Synopsis Gestion de L'Eau D'Irrigation Et Action Collective by : Zakaria Kadiri
Download or read book Gestion de L'Eau D'Irrigation Et Action Collective written by Zakaria Kadiri and published by Omniscriptum. This book was released on 2010-12 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: Le périmètre du Moyen Sebou, mis en eau à partir de 1998, s'inscrit dans une nouvelle approche, la Gestion Participative de l'Irrigation. Sa principale composante est la mise en place des Associations des Usagers des Eaux Agricoles (AUEA) censées prendre en charge la gestion et l'exploitation de l'infrastructure en place. La présente étude vise l'analyse de l'action collective à travers la gestion de l'eau d'irrigation au Moyen Sebou. Notre but est d'analyser le fonctionnement du périmètre et comment les agriculteurs s'approprient leurs associations pour développer leur territoire. Nous avons construit notre analyse sur quatre axes principaux: 1) La gestion de l'eau d'irrigation par les AUEA; 2) Le système financier et tarification de l'eau d'irrigation; 3) La gouvernance du périmètre; 4) La perception des agriculteurs. Notre travail a révélé de nombreux problèmes dans la gestion du périmètre et des institutions en place. Cela concerne la gestion financière (des bilans financiers entre la survie et le développement) et la mise en valeur agricole (des cultures sans grande valeur ajoutée et non valorisantes de l'eau

Book Synopsis Wetlands, agriculture and poverty reduction by : McCartney, Matthew
Download or read book Wetlands, agriculture and poverty reduction written by McCartney, Matthew and published by IWMI. This book was released on 2010 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: In many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.

Book Synopsis The Kingdom of Waalo by : Boubacar Barry
Download or read book The Kingdom of Waalo written by Boubacar Barry and published by Diasporic Africa Press. This book was released on 2017-10-26 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Situated along the Senegal River, the Kingdom of Waalo was the smallest of the Wolof states of Senegal, but it illustrates the broader consequences of a shift from trans-Saharan to trans-Atlantic commerce during a time of competing European, Muslim, and indigenous African forces. From the establishment of a French trading post in 1659 to the early nineteenth century, the history of Waalo was closely tied to French interests in St. Louis, popular revolutionary Islamic movements, and internal rivalries between competing royal families and provincial leaders. Stimulating Waalo's socio-political changes were the devastations and fluctuations of the Atlantic slave trade, as well as the Muslim attack on its aristocracy. Torn by internal divisions, devastated by French and Berber incursions, Waalo's institutions and its economy declined. Residents of Waalo sought their own solutions only for external agents to ruin their efforts. By the nineteenth century, the French attempted to establish a plantation economy in Waalo, culminating in their military control of the state and the Senegal valley. This newly translated study is a vital tool in our understanding of Senegal's history, its place in the era of trans-Saharan and trans-Atlantic commerce, and its development into the present. The book should be of value to African studies scholars, anthropologists, and historians of Africa, colonialism, empire, and post-colonialism.

Book Synopsis Quaternary Vegetation Dynamics by : Jürgen Runge
Download or read book Quaternary Vegetation Dynamics written by Jürgen Runge and published by CRC Press. This book was released on 2021-11-28 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.

Book Synopsis Groundwater Resources of the World and Their Use by : Igorʹ Semenovich Zekt︠s︡er
Download or read book Groundwater Resources of the World and Their Use written by Igorʹ Semenovich Zekt︠s︡er and published by . This book was released on 2004 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph represents many years of groundwater data accumulation by a large number of noted hydrogeologists located throughout the world. It represents a multicultural approach to groundwater resources and their use. As a result, many of the fundamental concepts in hydrogeology are interpreted slightly differently in other countries. In fact, there are a number of hydrogeologic phenomena introduced that for the most part have not been presented internationally. Since various cultures review the science of hydrogeology with their own nuances, a substantial effort was made to provide classic references in the science of hydrogeology. The focus of the monograph was to present data and scientific principals, which are relevant to groundwater use in each of the countries. This monograph represents a major undertaking by hydrologists and hydrogeologists around the world. Although the fundamental groundwater resource data may change slowly over time, the groundwater use data is rapidly changing. Consulting hydrogeologists, engineers, chemists, geologists, biologists, health officials, and government environmental administrators will find this baseline document of substantial value. It is fully anticipated that this book will serve as the first addition of a series on groundwater resources of the world and their use.
