Book excerpt: Designed for advanced level secondary students, this geography text studies desertification, the encroachment of arable land by desert which threatens an estimated 35% of the Earth's land surface. It explains the causes of desertification, how it can be measured and combatted, and questions whether the situation is actually happening at the scale suggested. The author focuses on questions that have made desertification a major issue, and highlights the difficulties involved in dealing with such a broad-scale physical and social topic. Case study material and exercises are included in the text.

Book excerpt: The United Nations Water Conference (in Argentina in March 1977) and the United Nations Conference to Combat Desertification (in Kenya in August 1977) reflect the worldwide attention that recent global food shortages and growing populations have drawn to the destruction of arable and potentially arable land. This collection of articles focuses on a primary form of such destruction: desertification—the creation of desert-like conditions in arid or semiarid regions either by changes in climate patterns or by human mismanagement, or both. The contributors—representing a range of disciplines—examine and evaluate the social, political, economic, environmental, and technical problems related to the causes and effects of desertification.
Download or read book Desertification written by Monique Mainguet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controversial, and often discussed with passion and vehemence, desertification is a problem on whose solution the survival of millions of humans is dependent. This book aims at an understanding of what is commonly called "desertification" - a term which has a connotation of irreversibility, spreading and emergence of desert-like landscapes: "land degradation" is proposed to replace it. The purpose is to present what has happened in reality, and what might be done. Illustrative worldwide analyses allow a more realistic evaluation of global land degradation. Each level of technology, excessive or insufficient, creates its own mismanagement. This is reflected in a decrease in soil productivity and eventually land degradation. The benefit to the reader is an awareness of the ecozones which have undergone the most severe land degradation, and a global overview of the phenomena, mechanisms and existing solutions.
Download or read book Combating Desertification in Asia Africa and the Middle East written by G. Ali Heshmati and published by Springer Science & Business Media. This book was released on 2013-07-01 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about the ‘how’ of desertification control as opposed to an analysis of the ‘why’ and fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands. There are numerous illustrations to show the successful techniques. This compilation demonstrates that desertification and land degradation can be controlled and reversed with existing techniques in such widely varying environments as the Sahel of Africa to Sri Lanka and the Philippines in SE Asia, from mountains in Lesotho to low lands on desert margins in Mongolia. Proven approaches include technical interventions, changes in governance and to the legislative framework and policy reform. The book fills a gap in the desertification-related literature in that it shows what to do in situations ranging from fixing mobile sands to arresting accelerated soil erosion in sloping lands.

Download or read book Sustainable Land Use in Deserts written by Siegmar-W. Breckle and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changing desert areas for land use implies a lot of ecological problems. These and related ones are dealt with in this book covering various interdisciplinary and international aspects. Large areas in arid and semi-arid regions are already polluted in various ways. One of the biggest problems is the anthropogenic salinization by inadequate means of agriculture and irrigation. Additionally, most arid areas in the world are dramatically overgrazed. Methods and practices of a sustainable land use in deserts are urgently needed in many arid regions. This book gives a broad survey on some of the affected regions of the world as well as some case studies from elsewhere (Aral Sea, Negev desert, Namib desert etc.). Thus, basic and applied sciences are brought together. Water management in deserts, grazing systems or reclamation of desertified areas are among the topics of this book, as well as social and economic aspects.

Download or read book The Threatening Desert written by Alan Grainger and published by Routledge. This book was released on 2013-11-05 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990

It is a business primer, detailing the fault lines that will confront the man or woman intent on making a mark on Nigeria’s business landscape. It is also the history of contemporary Nigeria from just before the civil war and right through successive military regimes to the dawn of democracy. Then it is, finally, the detailed account of environmental activism and the travels across the Sahara desert from London to Nigeria, and Nigeria to London, in the quest to stop the menace - desert encroachment and desertification. In telling his life story as a business man and building engineer, husband and father, adventurer and environmentalist, Newton Jibunoh takes us on an excursion through the alleyways of power becoming at once a full participant in Nigeria’s history through his work and friendships. This is a compelling human portrait of a larger-than-life personage.
