Book excerpt: 'Living on the Edge' examines the function of the Sahel region of Africa as an important wintering area for long-distance migrant birds. It describes the challenges the birds have to cope with – climate change, of course, and rapid man-made habitat changes related to deforestation, irrigation and reclamation of wetlands. How have all these changes affected the birds, and have birds adapted to these changes? Can we explain the changing numbers of breeding birds in Europe by changes in the Sahel, or vice versa? Winner of the BB/BTO Best Bird Book Award 2010 The Jury commented: "It is a tremendous book in every department. It marks a step-change in our knowledge of the ecology of this critically important region in the European-African migration system and of the many species (familiar to us on their breeding grounds) that winter there. The authors combine the latest scientific information with vivid descriptions of landscapes and animals. Their book is richly illustrated with large numbers of drawings, maps and photographs by acclaimed experts. The wealth of coloured graphics has been particularly well thought out and encourages readers to delve into the figures and learn more about the region, rather than having the (all-too-common) opposite effect. Summing up, the jury praises not just the high quality of the texts, the information and the illustrations, but also the sheer pleasure of reading the book: "One of the key attributes of a good book is to be able to grip the reader's attention and transport him or her to another place. We feel confident that [Living on the edge] will have that effect."

Available in PDF, EPUB and Kindle. Book excerpt: The conference "Combating Desertification with Plants" was held in Beer Sheva, Israel, from November 2-5, 1999, and was attended by 70 participants from 30 countries and/or international organisations. Desertification - the degradation of soils in drylands - is a phenomenon occurring in scores of countries around the globe. The number of people (in semiarid regions) affected by the steady decline in the productivity of their lands is in the hundred millions. The measures required to halt and reverse the process of desertification fall into many categories - policy, institutional, sociological-anthropological, and technical. Although technical "solutions" are not currently in vogue, the conference organizers felt that perhaps the pendulum had swung too far in the direction of "participatory approaches." Hence IPALAC - The International Program for Arid Land Crops - whose function is to serve as a catalyst for optimizing the contribution of plant germplasm to sustainable development in desertification-prone regions - felt the time was opportune for providing a platform for projects where the "plant-driven" approach to development finds expression. Some 45 papers were delivered at the conference, falling into the categories of this volume: Overview, Potential Germplasm for Arid Lands, Introduction, Domestication and Dissemination of Arid Land Plants, Land Rehabilitation, and Mechanisms of Plant Transfer. The conference was funded by UNESCO (Division of Ecological Sciences), the Ministry of Foreign Affairs of Finland, and MASHAV, Israel's Center for International Development Cooperation.

Download or read book Governing Africa s Forests in a Globalized World written by Laura A. German and published by Earthscan. This book was released on 2009-12 with total page 445 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many countries around the world are engaged in decentralization processes, and most African countries face serious problems with forest governance, from benefits sharing to illegality and sustainable forest management. This book summarizes experiences to date on the extent and nature of decentralization and its outcomes, most of which suggest an underperformance of governance reforms, and explores the viability of different governance instruments in the context of weak governance and expanding commercial pressures over forests. Findings are grouped into two thematic areas: decentralization, livelihoods and sustainable forest management; and international trade, finance and forest sector governance reforms. The authors examine diverse forces shaping the forest sector, including the theory and practice of decentralization, usurpation of authority, corruption and illegality, inequitable patterns of benefits capture and expansion of international trade in timber and carbon credits, and discuss related outcomes on livelihoods, forest condition and equity. The book builds on earlier volumes exploring different dimensions of decentralization and perspectives from other world regions, and distills dimensions of forest governance that are both unique to Africa and representative of broader global patterns. Authors ground their analysis in relevant theory while attempting to distill implications of their findings for policy and practice.
Download or read book The End of Desertification written by Roy H. Behnke and published by Springer. This book was released on 2016-04-12 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: The question in the title of this book draws attention to the shortcomings of a concept that has become a political tool of global importance even as the scientific basis for its use grows weaker. The concept of desertification, it can be argued, has ceased to be analytically useful and distorts our understanding of social-environmental systems and their resiliency, particularly in poor countries with variable rainfall and persistent poverty. For better policy and governance, we need to reconsider the scientific justification for international attempts to combat desertification. Our exploration of these issues begins in the Sahel of West Africa, where a series of severe droughts at the end of the 20th century led to the global institutionalization of the idea of desertification. It now seems incontrovertible that these droughts were not caused primarily by local land use mismanagement, effectively terminating a long-standing policy and scientific debate. There is now an opportunity to treat this episode as an object lesson in the relationship between science, the formation of public opinion and international policy-making. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept. Despite an increasingly sophisticated understanding of dryland environments and societies, the uses now being made of the desertification concept in parts of Asia exhibit many of the shortcomings of earlier work done in Africa. It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. This book is an effort to critically examine that experience and accelerate the learning process in other parts of the world.

This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial photography has revealed the striking, widespread phenomenon of repeating patterns of vegetation in more arid areas of the world. Two interdependent phases, bands of dense and sparse vegetation, alternate in the landscape. This volume synthesizes half a century's accumulated knowledge of both theoretical and applied landscape function from a variety of these regions. It covers structure, dynamics, and methods of study, as well as disturbances to these landscapes and relevant management issues. Various chapters discuss the role of modeling in answering questions about the origins and complex processes of banded landscapes.

Book excerpt: Niger is sand, light, and heat. Starting from the necessity of the Mission Catholique du Dosso, which has worked in Niger for several years, this book speaks about the Nigerien situation which is characterized by a countrywide spread of poverty. Along with studying the country’s environmental, geographical conditions, the book discusses raw earth architecture in both vernacular and contemporary contexts. A number of the most common techniques are described. The possibilities for these methods to adapt to the contemporary language of architecture without losing the technical and physical benefits inherent in them are illustrated. The book embraces some topics that are not common but highly relevant in the Developing World, such as identity through the evolution of architecture and the value of transmitting knowledge related to the vernacular building process. Nowadays, Niger’s condition is characterized by a lack of resources, both physical and cultural. Earthen technology appears to be a valid solution in this situation for the creation of an environmentally sustainable approach. The book aims to provide an overview of the possibility of constructing new buildings related to the climate and traditional context, applying vernacular technology and solutions in a contemporary application. Providing a balance between teaching vernacular knowledge and the contemporary architectural language could help face this out-of-resource situation, aiming to get comfortable and affordable living spaces.

Download or read book Forest Degradation Around the World written by MOHD NAZIP SURATMAN and published by BoD – Books on Demand. This book was released on 2020-02-26 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth in the human population has forced mankind to convert forested land into other land uses such as agricultural land, residential, urban, road construction and mining activities. The degradation of forest due to anthropogenic activities is significantly reducing forests in the world. These practices result in significant impacts on the forest structure, species composition and ecology, which will consequently reduce forest productivity and ecosystem functions. Due to deforestation, half of the earth's vegetation surface has reduced to one-third, resulting in large degraded areas. The significant reduction of the forest areas requires appropriate planning for sustainable management of the forests. This book reviews the extent and consequences of deforestation around the world. It highlights case studies of the causes of deforestation in Malaysia, Korea, India, Bangladesh, Columbia, Brazil and Mali. It is hoped that the book will provide insights on the importance of effective forest planning and management for the sustainable development of forest resources.
