Book excerpt: Rainfed agriculture is generally overlooked by development investors, researchers and policy makers due to limited confidence in its ability to increase agricultural production and development. However, research undertaken by a team of leading scientists from global organizations demonstrates its potential in achieving food security, improving livelihoods and most importantly addressing issues of equity and poverty reduction in dryland areas - the hot spots of poverty. On the basis of case studies from varied agricultural and ecological regions in Asia and Africa, chapters discuss the need for adopting new paradigms between rainfed and irrigated agriculture, catchment/micro-watershed management approaches, upgrades in science-based development and more investments in rainfed areas. Yield gaps for major rainfed crops are analysed globally and possible ways and means including technological, social, and institutional options to bridge the yield gaps are discussed in detail. Covering areas such as rainwater harvesting and its efficient use, the rehabilitation of degraded land and assessment methods for social, environmental and economic impacts, this book will be necessary for both academics and policy makers working in water management, agriculture and sustainable development.

Download or read book Arid Lands Water Evaluation and Management written by Robert Maliva and published by Springer Science & Business Media. This book was released on 2012-06-09 with total page 1068 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of the global population lives in arid lands which have low rainfall and often lack the water required for sustainable population and economic growth. This book presents a comprehensive description of the hydrogeology and hydrologic processes at work in arid lands. It describes the techniques that can be used to assess and manage the water resources of these areas with an emphasis on groundwater resources, including recent advances in hydrologic evaluation and the differences between how aquifer systems behave in arid lands versus more humid areas. Water management techniques are described and summarized to show how a more comprehensive approach to water management is required in these areas, including the need to be aware of cultural sensitivities and conditions unique to many arid regions. The integration of existing resources with the addition of new water sources, such as desalination of brackish water and seawater, along with reusing treated wastewater, will be required to meet future water supply needs. Also, changing climatic conditions will force water management systems to be more robust so that future water supply demands can be met as droughts become more intense and rainfall events become more intense. A range of water management techniques are described and discussed in order to illustrate the methods for integrating these measures within the context of arid lands conditions.

Download or read book Challenges and Strategies of Dryland Agriculture written by S.C. Rao and published by Scientific Publishers. This book was released on 2011-01-01 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world has made remarkable progress in maintaining adequate food supplies during the past quarter century by introducing yield-increasing technologies such as better genetics, crop protection products, and more efficient use of fertilizers and irrigations. Far more people depend on irrigation in the modern world than during the times of ancient Sumeria. The spread of irrigation has been the key factor in increasing global crop yields. But future scarcity present the single biggest threat to future food production. The shift of water from agriculture to the growing cities and industry almost certainly will impact global food production. This means that dryland agriculture will be increasingly important in meeting food requirement for the growing population. Advaces in plant genetics and agronomic conservation technologies, when considered in concert, continue to provide the greatest opportunities to achieve sustainability and profitability in dryland agriculture and will continue to be the focus of the ARS research program. The ARS is please to join the crop Science Society of America and international center for Agriculture Research in Dry Areas (ICARDA) in sponsoring a symposium “Challenges and strategies for Dryland Agriculture” at the Trisocieties Annual Meeting in November 2002 at Indianapolis, IN. This special publication contains an impressive series of paper by international group of experts on dryland agricultural production, conservation, and policy. The principles, philosophies, and technologies presented in this publication have the potential to contribute to improve food security and livelihoods for the people in dryland regions of the world.

Download or read book Guidance on realizing real water savings with crop water productivity interventions written by Van Opstal, J., Droogers, P., Kaune, A., Steduto, P., Perry, C. and published by Food & Agriculture Org.. This book was released on 2021-03-18 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical document contains clear and practical guidelines on how to implement real water savings in agriculture through interventions for enhancing crop water productivity. A distinction is made between real water savings and “apparent” water savings. Apparent water savings record reductions in water withdrawals but do not account for changes in water consumption. Real water savings record reductions in water consumption and non-recoverable return flows (runoff or percolation). This guidance document emphasizes the paradox of water savings at field and basin scales, which usually do not translate into increased water availability for other users, as is commonly believed.

Download or read book Water and Cereals in Drylands written by Parviz Koohafkan and published by Routledge. This book was released on 2012-05-04 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This topic is central to contemporary concerns for more sustainable agricultural development. This is a well-written and clear book, with excellent data, tables and illustrations, addressing issues of water use, climate change, poverty and small farmers. The authors are highly respected and complement each other's acknowledged international expertise.' Professor Jules Pretty, University of Essex, UK 'This useful guide shows that there is great potential for increasing the productive capacity of smallholder farms in the drylands via a range of water management techniques, from the simple to the more complex. Providing a theoretical grounding and a practical guide, Water and cereals in the drylands will appeal to workers on-location as well as students, researchers and policymakers.' New Agriculturalist Cereals are by far the most important source of food throughout the world, either directly for human consumption or indirectly in the form of animal feed for livestock products consumed as food. With world population set to rise to nine billion by 2050, there is an urgent need to examine ways to increase cereal production. Indeed recently the future of cereal production and consumption has been complicated by rising energy prices and the economics of biofuels, which are competing for the use of cereals. One way to increase cereal production is by the more effective use of marginal dryland areas. This book reviews the potential for increased cereal production in drylands across the world, from the USA, Australia and Southern Europe to Asia and Africa. It describes how improved water conservation, water harvesting and investment options can contribute to this, and suggests policies for the more efficient use of existing natural resources in order to lessen the dependence of agriculture on further irrigation development.
