Available in PDF, EPUB and Kindle. Book excerpt: Halophytes for Food Security in Dry Lands addresses the concerns surrounding global food scarcity, especially focusing on those living in arid and dry lands The book touches on food crises in dry regions of the world and proposes halophytes as an alternate source of consumption for such areas. Halophytes, those plants that thrive in saline soil and provide either food source options themselves, or positively enhance an eco-system’s ability to produce food, and are thus an important and increasingly recognized option for addressing the needs of the nearly 1/6 of the world’s population that lives in these arid and semi-arid climates. Including presentations from the 2014 International Conference on Halophytes for Food Security in Dry Lands, this book features insights from the leading researchers in the subject. It is a valuable resource that includes information on the nutritional value of halophytes, their genetic basis and potential enhancement, adaption of halophytes, and lessons learned thus far. Provides comprehensive coverage of the importance and utilization of halophytes to compensate the demand of food in whole world especially in the dry regions Contains insights from ecological to molecular fields Includes edible halophytes as well as those that enhance food-producing eco-systems Presents information for improving abiotic stress tolerance in plants

Download or read book Agriculture in Dry Lands written by I. Arnon and published by Elsevier. This book was released on 2012-12-02 with total page 992 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout history, man has, by over-use, consistently reduced the productive capacity of dry lands. This degradation of one-third of the land area of the globe is, unfortunately, increasing. In recent years, world interest has turned to the problems of pollution of the environment and the impending food shortage as world population grows explosively. Thus the attention of international and other agricultural bodies has turned to the need for preserving and developing more effectively the agricultural potential of these areas. This book provides a comprehensive review of present knowledge of the agriculture of dry lands, with special emphasis on measures for conserving their natural resources. Management practices are described which aim at optimizing productivity of rainfed and irrigated agriculture without adverse effects on sustainability. Land use in the dry regions, and its evolution throughout history is described and analysed, and the lessons to be learnt from destructive technologies are stressed. In particular, current proposals for an alternative agriculture are discussed and their justification is questioned. This is a generalist work, which specialists can also find interesting, not only in their own discipline but as a concise way of acquainting themselves with the state-of-the-art in associated fields. Increasing specialisation with each discipline using its own vocabulary leads inevitably to communication problems, and the need for multi-disciplinary teams makes inter-discipline communication indispensible.
Download or read book Food from dry lands written by Th. Alberda and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early seventies, scientists in Israel and The Netherlands started a cooperative project on actual and potential production under semi-arid conditions. In Israel research concentrated on primary production of natural pastures and small grain crops, and on the associated secondary production of small ruminants. Most of the experimental work was carried out at the Migda Experimental Farm in the semi-desert of the northern Negev where the long term average annual rainfall is 250 mm. In The Netherlands existing facilities in Wageningen were used for measuring growth, photosynthesis and transpiration of Negev pasture plants and small grains under controlled conditions, both as individual plants and as simulated swards and crops. The joint research program was initiated by the late N.H. Tadmor and A. Dovrat from Israel and by C.T. de Wit and Th. Alberda from The Netherlands and conducted by various scientists from both countries, some of whom are among the authors of this book. The experimental results first served as a basis for the development, calibration and validation of simulation models of the growth and water use of pasture and crops. Subsequently, additional models were developed, allowing incorporation of socio-economic considerations, both at the farm and regional level, so harnessing the research results for analysis of regional development possibilities.

Download or read book The Impact of Climate Change on Drylands written by A.J. Dietz and published by Springer Science & Business Media. This book was released on 2006-04-11 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sahelian West Africa has recovered from the disastrous droughts of the 1970s and 1980s. People have learned to adapt to risk and uncertainty in fragile dryland environments. They, as well as global change scientists, are worried about the impact of climate change on these West African drylands. What do the experiences of the last thirty years say about the preparedness for higher temperatures, lower rainfall, and even more variability? Detailed studies on Dryland West Africa as a whole, and on Burkina Faso, Mali and Northern Ghana in particular show an advanced coping behaviour and increased adaptation, but also major differences in vulnerability and coping potential. Climate change preparedness programmes have only just started and require more robust support, and more specific social targeting, for a population which is rapidly growing, even more rapidly urbanising, and further integrating in a globalised economy. This book is the first of its kind with a comprehensive analysis of climate change experiences in West African drylands, with attention for pathways of change and the diversity of adaptation options available. This book is of interest to scientists studying global and climate change, especially dealing with issues of adaptation. Social scientists, economists, geographers and policy makers concerned with West Africa should also read this book.
Download or read book Confronting Drought in Africa s Drylands written by Raffaello Cervigni and published by World Bank Publications. This book was released on 2016-05-10 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drylands are at the core of Africa’s development challenge. Drylands make up about 43 percent of the region’s land surface, account for about 75 percent of the area used for agriculture, and are home to about 50 percent of the population, including a disproportionate share of the poor. Due to complex interactions among many factors, vulnerability in drylands is high and rising, jeopardizing the long-term livelihood prospects for hundreds of millions of people. Climate change, which is expected to increase the frequency and severity of extreme weather events, will exacerbate this challenge. African governments and their partners in the international development community stand ready to tackle the challenges confronting drylands, but important questions remain unanswered about how the task should be undertaken. Do dryland environments contain enough resources to generate the food, jobs, and income needed to support sustainable livelihoods for a fast growing population? If not, can injections of external resources make up the deficit? Or is the carrying capacity of drylands so limited that outmigration should be encouraged? Based on analysis of current and projected future drivers of vulnerability and resilience, the report uses an original modeling framework to identify promising interventions, quantify their likely costs and benefits, and describe the policy trade-offs that will need to be addressed. By 2030, economic growth leading to structural change will allow some of the people living in drylands to transition to non-agriculture based livelihood strategies, reducing their vulnerability. Many others will continue to rely on livestock keeping and crop farming. For the latter group, a number of “best bet†? interventions have the potential to make a significant difference in reducing vulnerability and increasing resilience. This report evaluates the opportunities and challenges associated with these interventions, and it draws a number of conclusions that have important implications for policy making.
Download or read book Sustainable Horticulture in Semiarid Dry Lands written by Shrikant Hiwale and published by Springer. This book was released on 2015-03-16 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses ways of increasing production/unit area by making full use of the soil and water under the harsh climatic conditions of semiarid areas. This leads to improved sustainability, increased availability of fresh produce, which is vital for human health and higher incomes for small and marginal farmers. Arid and semiarid areas account for almost 70 per cent of the total cropped area of India. In these areas physical constraints like low and erratic rainfall, high temperature, high wind velocity, low fertility, poor soil structure, salinity of soil and ground water all limit reliable crop production. In the absence of any type of aggregation, the soils are highly erodible, lack structure and have a very coarse in texture with low water holding capacity. Intensive agricultural practices, increasing population pressure, climatic changes, environmental pollution, loss of biodiversity, soil erosion, salinization and water depletion are all threatening the sustainability of agriculture. In view of the mounting demand for food, it is vital to link enhanced food production with nutritional security, conservation of natural resources, increasing farmers’ incomes, employment generation through agricultural diversification. Horticulture, particularly of fruit trees, can play a major role in solving the problem of nutrition, as fruits are rich source of vitamins and minerals and have antioxidant properties. Fruit trees, which are mostly deciduous, add leaf litter to the soil, and this ultimately helps to improve the condition of the soil. In addition, fruit trees are known to reduce soil erosion and reduce run off. The trees also play a major role in purifying the environment as they are the known carbon sequesters. Fruit-tree cultivation is a profitable preposition. There is no scope to increase the land surface; all increase in productivity therefore has to be from the available land. This means introducing cropping systems that can meet the basic food, fodder and fuel requirement of farming families.

This book was released on 2018-06-01 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although much is known about the processes and effects of desertification, land degradation and climate change, little is understood about the links between them. Less still is known about how these processes are likely to interact in different social-ecological systems around the world, or how societies might be able to adapt to this twin challenge. This book identifies key vulnerabilities to the combined effects of climate change and land degradation around the world. It identifies triple-win adaptations that can tackle both climate change and land degradation, whilst supporting biodiversity and ecosystem services. Desertification, Land Degradation and Climate Change : Assessment, Mitigation and Remediation research results in sustainable land management, land degradation status and mitigation in the world. It includes background chapters with continental and international perspectives dealing with desertification, land degradation and climate change studies. The book assembles various topics of interest for a large audience. They include carbon sequestration and stocks, modern techniques to trace the trends of land degradation, traditional and modern approaches of resource-base conservation, soil fertility management, reforestation, rangeland rehabilitation, land use planning, GIS techniques in desertification risk cartography, participatory ecosystem management, policy analyses and possible plans for action. Various climatic domains in Africa, Asia, Europe and the Americas are covered. The book will be of interest to a variety of environmental scientists, agronomists, national and international policy makers and a number of organizations dealing with sustainable management of natural resources.

Book excerpt: The livelihoods of millions of people in developing countries, which depend on dryland agriculture to ensure their food security and their well-being, could be improved measurably by gains in agricultural crop yields. This book describes lessons learnt from an innovative scheme in India that improved crop yields in drylands. It shows how the scheme can be scaled up for other dryland regions of the world. The scheme uses localized soil nutrient analyses to create an integrated, climate smart fertilizer and planting plan that maximises yields for farmers. This book describes how a partnership between a global scientific organization (such as International Crops Research Institute for the Semi-Arid Tropics, ICRISAT) and state and non-state actors can provide a route to equitable growth, specifically for small and marginal farmers, and how this approach can be replicated worldwide to enhance rural livelihoods. This strategic collaboration and its conceptual and functional design is fully outlined, as well as the scheme's implementation and the effective monitoring and learning process that has been created.
