Download or read book Progressive Development written by Arie S. Issar and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is based on the results of the investigations of the authors in the semi-arid and arid regions (ASAR) of the globe. These investigations brought to the conclusion that the warming climate will cause the drying up of the water resources in these regions. In this case the principles of Sustainable Development will not be able to avert forthcoming catastrophes. These conclusions brought to the compilation of the policy of "Progressive Development", emphasising investment in the development of new water resources and changing the natural environments while advancing the local populations on the dimension of knowledge by education.

This book was released on 2018-10-29 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pastoral livestock production is crucial to the livelihoods and the economy of Africa’s semiarid regions. It developed 7,000 years ago in response to long-tern climate change. It spread throughout Northern Africa as an adaptation to the rapidly changing and increasingly unpredictable arid climate. It is practiced in an area representing 43% of Africa’s land mass in the different regions of Africa, and in some regions it represents the dominant livelihoods system. It covers 36 countries, stretching from the Sahelian West to the rangelands of Eastern Africa and the Horn and the nomadic populations of Southern Africa, with an estimate of 268 million pastoralists. The mobility of pastoralists exploiting the animal feed resources along different ecological zones represents a flexible response to a dry and increasingly variable environment. It allows pastoral herds to use the drier areas during the wet season and more humid areas during the dry season. It ensures pastoral livestock to access sufficient high-quality grazing and create economic value. The objectives of this report are to investigate the current situation of pastoralism and the vulnerability context in which pastoralism currently functions and to outline the policy, resilience programming, and research areas of intervention to enhance the resilience of pastoral livelihoods systems. Scholarly views of pastoralism’s ecological impact have grown more positive since the early 1990s, when a new understanding of dryland dynamics led to the so-called new rangeland paradigm. The new rangeland paradigm represents a shift in the wider discourse on pastoralism from the earlier debates based on the “tragedy of the commons.” The new rangeland paradigm has provided a more comprehensive understanding of the drylands and shown that mobility is an appropriate strategy to exploit the natural resource base in these areas. In recent decades, the adaptability and mobility of pastoralism in relation to resource variability have been undermined by factors that are embedded in the institutional environment and policy that shape the vulnerability context of pastoralism. The report analyzes five factors that undermine the pastoral livelihoods resilience and the implications of these factors for the viability of pastoralism. On the basis of the analysis of vulnerability contexts that shape pastoralism, the report identifies interventions for increasing pastoral resilience.
Download or read book Economics of Dryland Management written by John A. Dixon and published by Routledge. This book was released on 2013-11-05 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have always had land in which the agricultural productivity is limited because there is not enough moisture. Systems of farming and burning often degrade dryland further until it is desert. Today, however, the problem is becoming much more serious. Over 20 per cent of the world's population lives in dryland areas, and unless action is taken drylands will increase dramatically. This book focuses on the people who live and .farm in the drylands, their use of land resources and the economic returns from their decisions. In a clear and thorough economic appraisal, the authors show how it is still possible to arrest the problem. Originally published in 1989

Download or read book Climate Change Adaptations in Dryland Agriculture in Semi Arid Areas written by Xavier Poshiwa and published by Springer Nature. This book was released on 2022-02-10 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the approaches for achieving trans-disciplinary research integration for “semi-arid dryland agriculture systems” under changing climates, while also identifying the elements of a collaborative research agenda that are needed to advance global food security. The book emphasizes climate change being a reality and how drylands are bearing the brunt in diverse ways. The major impact of dryland agriculture is on communities that need to: avoid the short- and long-term impacts of the changing climate; adapt strategies that can minimize these impacts; and be able to mitigate climate change, for which they need climate smart interventions. These interventions are only realized through knowledge and experience sharing among stakeholders from different sectors and backgrounds. It is in this context that the publication was seen as a necessity in order to bring together ideas that will transform lives and build adaptation capacities, thereby providing the much-needed products in communities leading to development

Download or read book Economics of Water Use in Semi Arid Environment written by Issam A.W Mohamed and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental, climatic and economic human influences contribute to the problem of water scarcity in arid and semi-arid areas of the world, particularly in the less developed countries. This has impeded economic development in these regions. Thus, the call is for better methodological approaches for investigating the problem from an interdisciplinary perspective and at a local scale, i.e., the bottom-up approach. This study investigates the nature of water use in a selected drought-inflicted village and develops an analytical framework for assessing the water demands of alternative economic development scenarios. A review of hydro-climatologically characteristics, land use practices, and technological development provides information on water resources availability and human activities in the region. Surveys of human activities and water use in the study village, Kutum indicate the following conditions: water scarcity, unsustainable agricultural development, and subsequent food and economic insecurity. Further investigations indicate that groundwater is the most dependable source of water. Its use is dominated by agricultural activities especially irrigation and animal rearing. These are the most water intensive activities based on the ratio of water use to income generation. Results of the study provide useful information for the development of predictive models and water conservation strategies. Estimates of direct and total requirements of both economic and ecological commodities showed sparse sectoral interdependence within the economic system but a heavy dependence of the economy on the environment. Such dependence is more on water, a scarce commodity in this semi-arid environment. The most intensive users of water based on the direct effects include animal husbandry, building and irrigated agriculture; based on total effects are catering, building and animal husbandry, in descending order.
