Available in PDF, EPUB and Kindle. Book excerpt: The image of Africa in the modern world has come to be shaped by perceptions of the drylands and their problems of poverty, drought, degradation, and famine. Michael Mortimore offers an alternative and revisionist thesis, dismissing on theoretical and empirical grounds the conventional view of runaway desertification, driven by population growth and inappropriate land use. In its place he suggests a more optimistic model of sustainable land use, based on researched case studies from East and West Africa where indigenous technological adaptation has put population growth and market opportunities to advantage. He also proposes a more appropriate set of policy priorities to support dryland peoples in their efforts to sustain land and livelihoods. The result is a remarkably clear synthesis of much of the best work that has emerged over past years.

Available in PDF, EPUB and Kindle. Book excerpt: The traditional image of contemporary Africa is of a continent dogged by poverty, drought, degradation and famine. This study, drawing on the best work of the past decade and based on researched case studies from East and West Africa, rejects the notion of runaway desertification, driven by population growth and inappropriate land use. It suggests a more optimistic model of sustainable land use and an appropriate set of policy priorities to support dryland peoples in their efforts to sustain land and livelihoods.
Download or read book Desert Edens written by Philipp Lehmann and published by Princeton University Press. This book was released on 2024-12-17 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: How technological advances and colonial fears inspired utopian geoengineering projects during the late nineteenth and early twentieth centuries From the 1870s to the mid-twentieth century, European explorers, climatologists, colonial officials, and planners were avidly interested in large-scale projects that might actively alter the climate. Uncovering this history, Desert Edens looks at how arid environments and an increasing anxiety about climate in the colonial world shaped this upsurge in ideas about climate engineering. From notions about the transformation of deserts into forests to Nazi plans to influence the climates of war-torn areas, Philipp Lehmann puts the early climate change debate in its environmental, intellectual, and political context, and considers the ways this legacy reverberates in the present climate crisis. Lehmann examines some of the most ambitious climate-engineering projects to emerge in the late nineteenth and early twentieth centuries. Confronted with the Sahara in the 1870s, the French developed concepts for a flooding project that would lead to the creation of a man-made Sahara Sea. In the 1920s, German architect Herman Sörgel proposed damming the Mediterranean in order to geoengineer an Afro-European continent called “Atlantropa,” which would fit the needs of European settlers. Nazi designs were formulated to counteract the desertification of Eastern Europe and Central Asia. Despite ideological and technical differences, these projects all incorporated and developed climate change theories and vocabulary. They also combined expressions of an extreme environmental pessimism with a powerful technological optimism that continue to shape the contemporary moment. Focusing on the intellectual roots, intended effects, and impact of early measures to modify the climate, Desert Edens investigates how the technological imagination can be inspired by pressing fears about the environment and civilization.

Download or read book Unifying Geography written by David T. Herbert and published by Routledge. This book was released on 2004-08-05 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: It can be argued that the differences in content and approach between physical and human geography, and also within its sub-disciplines, are often overemphasised. The result is that geography is often seen as a diverse and dynamic subject, but also as a disorganised and fragmenting one, without a focus. Unifying Geography focuses on the plural and competing versions of unity that characterise the discipline, which give it cohesion and differentiate it from related fields of knowledge. Each of the chapters is co-authored by both a leading physical and a human geographer. Themes identified include those of the traditional core as well as new and developing topics that are based on subject matter, concepts, methodology, theory, techniques and applications. Through its identification of unifying themes, the book will provide students with a meaningful framework through which to understand the nature of the geographical discipline. Unifying Geography will give the discipline renewed strength and direction, thus improving its status both within and outside geography.

Download or read book Food Sovereignty Agroecology and Biocultural Diversity written by Michel. P. Pimbert and published by Routledge. This book was released on 2017-11-01 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contestations over knowledge – and who controls its production – are a key focus of social movements and other actors that promote food sovereignty, agroecology and biocultural diversity. This book critically examines the kinds of knowledge and ways of knowing needed for food sovereignty, agroecology and biocultural diversity. ‘Food sovereignty’ is understood here as a transformative process that seeks to recreate the democratic realm and regenerate a diversity of autonomous food systems based on agroecology, biocultural diversity, equity, social justice and ecological sustainability. It is shown that alternatives to the current model of development require radically different knowledges and epistemologies from those on offer today in mainstream institutions (including universities, policy think tanks and donor organizations). To achieve food sovereignty, agroecology and biocultural diversity, there is a need to re-imagine and construct knowledge for diversity, decentralisation, dynamic adaptation and democracy. The authors critically explore the changes in organizations, research paradigms and professional practice that could help transform and co-create knowledge for a new modernity based on plural definitions of wellbeing. Particular attention is given to institutional, pedagogical and methodological innovations that can enhance cognitive justice by giving hitherto excluded citizens more power and agency in the construction of knowledge. The book thus contributes to the democratization of knowledge and power in the domain of food, environment and society.

Download or read book The African Roots of Marijuana written by Chris S. Duvall and published by Duke University Press. This book was released on 2019-05-09 with total page 269 pages. Available in PDF, EPUB and Kindle. Book excerpt: After arriving from South Asia approximately a thousand years ago, cannabis quickly spread throughout the African continent. European accounts of cannabis in Africa—often fictionalized and reliant upon racial stereotypes—shaped widespread myths about the plant and were used to depict the continent as a cultural backwater and Africans as predisposed to drug use. These myths continue to influence contemporary thinking about cannabis. In The African Roots of Marijuana, Chris S. Duvall corrects common misconceptions while providing an authoritative history of cannabis as it flowed into, throughout, and out of Africa. Duvall shows how preexisting smoking cultures in Africa transformed the plant into a fast-acting and easily dosed drug and how it later became linked with global capitalism and the slave trade. People often used cannabis to cope with oppressive working conditions under colonialism, as a recreational drug, and in religious and political movements. This expansive look at Africa's importance to the development of human knowledge about marijuana will challenge everything readers thought they knew about one of the world's most ubiquitous plants.

Download or read book Exploring Natural Hazards written by Darius Bartlett and published by CRC Press. This book was released on 2018-04-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sendai Framework for Disaster Risk Reduction 2015–2030 has identified four priority areas for Disaster Risk Reduction: understanding disaster risk; strengthening disaster risk governance to manage disaster risk; investing in disaster risk reduction for resilience and enhancing disaster preparedness for effective response; and to "Build Back Better" in recovery, rehabilitation and reconstruction. Although tremendous progress has been made in recent decades in understanding the workings of the Earth systems and, in particular, its impacts on and responses to human actions, there remains a continuing and pressing need for knowledge that will allow society to simultaneously reduce exposure to global environmental hazards, while also meeting economic development goals. Exploring Natural Hazards: A Case Study Approach, contributes to the knowledge showcasing advanced practices for the monitoring of natural hazards. Through each case study, the book examines mainly hazards arising from processes within the hydrosphere and atmosphere, triggered or exacerbated by inputs to and transfers of energy between environmental components. It discusses the causes of these phenomena, and ways in which improved policy making, sometimes coupled with the application of appropriate modern technologies, can help to reduce people’s exposure to harm. Discussing challenges, lessons learned and recommendations, this book provides a snapshot of issues related to tropical cyclones and typhoons, desertification, floods, lightning as a hazard and the need for alert systems. It is a valuable resource for practitioners and professionals alike, for researchers, students and others who work at the intersection between environmental hazards, sustainable development and social justice.
Download or read book The Dry Forests and Woodlands of Africa written by Emmanuel N. Chidumayo and published by Routledge. This book was released on 2010-09-23 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.
