Available in PDF, EPUB and Kindle. Book excerpt: Plant Resources of Arid and Semiarid Lands: A Global Perspective is a collection of papers that evaluates the existing native plant resources in the arid and semiarid regions. The papers deal with the resources found in these arid regions such as food potential, forage, fuel, fiber, medicinal or industrial uses. The book covers the arid regions of Africa, Australia, the Indian subcontinent, Middle East, North America, China, South America, and the USSR. The treatment of these regions includes geographical descriptions such as area, annual precipitation, temperature, humidity, wind ranges or patterns, and seasons. These papers also discuss the effects of topography on water drainage and loss, the basic soil types, holding capacity, water runoffs, and the availability of water (surface and subsurface), The book examines the current and projected growth rates for relevant countries and dry regions in each continent. These papers discuss the economic output from arid lands, the balance of trade, current or developing resources, as well as the prospects of these countries with dry regions. The book also focuses on the types of plants found in these regions whether these are used for food, forage, medicine or for industry. This collection is suitable for environmentalists, ecologists, sociologist, anthropologists, and researchers involved in biological and environmental conservation.

Book excerpt: Since 1962 the Desert Institute of the former Academy of Science of the USSR has been conducting research work in the arid and semi-arid zones of central Asia. This outstanding experience in desert and desertification problems, and the possibilities of sustainable land use under difficult environmental conditions is summarized here. The book also gives an overview of the Institute's consulting work within the framework of international projects. This is the first publication allowing readers outside the Russian-speaking world to obtain concise information about the specific constraints and development possibilities of central Asian drylands.

This book was released on 2012-12-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desertification (land degradation in arid, semi-arid and dry sub-humid areas resulting mainly from adverse human impacts) is the main environmental problem of dry lands, which occupy more than 40 per cent of the total global land area. The phenomenon threatens about 3.6 billion hectares and currently affects the livelihood of about 900 million people. Thl! world is now losing annually about 1.5 million hectares of total irrigated lands (240 million hectares) due mostly to salinization, mainly in drylands. Salt affected soils are widely distributed throughout the arid and semi-arid regions, and particularly severe in China (7 million ha), India (20 million ha), Pakistan (3.2 million ha), USA (5.2 million ha), as well as Near East, southern Europe and elsewhere. Demands on production have increased the pressure on existing productive land and moved the limits of production onto increasingly marginal lands. Wise land-use practices have yet to be developed for such conditions. The Executive Director of UNEP reported to the Governing Council in February 1992 concerning the "Status of Desertification and Implementation of the United Nations Plan of Action to Comtat Desertification (PACD)". The Report concludes that major efforts to implement the PACD had gJne into supporting measures rather than concrete corrective field operations. Little evidence of progrl!ss was found in irrigated croplands, rainfed croplands or rangelands. It was recommended that every piece of land should be used in keeping with its ecological characteristics, natural capabilities and constraints.

This book was released on 2010-07-29 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interactions: Food, Agriculture And Environment is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Interactions: Food, Agriculture and Environment focuses on methods to ensure the development of agriculture and food production to be in dialectic unity with the surrounding natural environment. In every country of the world agriculture always faces complex problems: how to significantly increase production of agricultural products to supply the population with sufficient food, and industry with sufficient raw materials, and how to satisfy the permanently growing demand. The acuteness of this task has always been linked with the demographic factor and the need to guarantee the population with a high living standard free of starvation and poverty. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.
Download or read book Governing Global Desertification written by Pierre Marc Johnson and published by Routledge. This book was released on 2016-12-05 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Desertification affects 70 per cent of the world's arable lands in more than 100 countries. Inextricably linked to poverty, it is estimated that the livelihood of 250 million people are directly affected while another billion living in rural drylands are threatened by this phenomenon. This volume examines the United Nations Convention to Combat Desertification (UNCCD) signed in 1994. It studies the links between land degradation and poverty, the role of civil society and good governance in implementing the UNCCD and the various approaches to fighting desertification. Furthermore, it assesses the National Action Programmes, development planning and new avenues for strengthening implementation. Synthesizing the main strengths and weaknesses of the UNCCD as a tool for environmental and developmental governance, this informative volume highlights the main challenges facing the UNCCD in the future.
