Download or read book Rainwater Harvesting for Agriculture in the Dry Areas written by Theib Y. Oweis and published by CRC Press. This book was released on 2012-05-21 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dry areas suffer not only from limited rainfall but also ‘natural leakage’—90% of rainwater is lost directly or indirectly, and is unavailable for agriculture or domestic use. Water harvesting is a low-cost, easy-to-use, environmentally-friendly way to recover a large part of this lost water. How does water harvesting work? Which sites or areas are best suited and how can these areas be identified? How to design, build and maintain a water harvesting system tailored to local needs? How can water harvesting contribute to combating land degradation, enhancing food security and adapting to climate change? This book provides the answers. The book is based on many years of research, training and development by three of the world’s leading experts in water management and agriculture. It is authoritative, comprehensive, and easy to read, containing practical examples, many illustrations and little jargon. This volume will be of great interest to researchers, development workers, farmers, policymakers, students of the natural sciences—in fact, anyone interested in efficient, sustainable management of water resources and agriculture.

This book was released on 2018 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Fresh water is a finite and a vulnerable resource that sustains life, development, and the environment. Approximately 80% of the world’s cultivable land depends on rainfall, interestingly rain-fed production produces up to 70% of the global food supply yet it’s the same system that has been threatened with frequent dry spells and long term droughts. Estimates show that uncertain weather conditions and insufficient water for irrigation could lead agricultural productivity in several countries to fall by up to 50% over the next decade, severely affecting their prospects of greater social and economic development. Rainwater harvesting is the collection and storage of any farm water either runoff or creek flow for irrigation use. Rainwater harvesting for supplemental irrigation is currently the best practice to mitigate the escalating issue of water shortage caused by concurrent agricultural droughts. One form of mitigating the negative effects of such droughts and dry spells is the establishment of small scale simple low cost supplemental irrigation schemes in rain-fed agriculture. This is to reduce the extent of crop failures and as well increase the water use efficiency WUE of crops. In a developing country like Uganda where more than 80% of the population lives in rural areas and their lives depends on rain-fed agriculture. Droughts and dry spells have greater consequences to the peoples’ survival and development. This study presents a sustainable economic solution for the problem of crop yield reduction due to short droughts during the rainy season, more particularly for maize as a staple crop. It aims at reducing maize crop failures by supplying supplemental irrigation during the critical growth stages of the plant. It employs FAO’s water productivity model (Aquacrop) to estimate and predict the potential economic benefits of supplemental irrigation as well as the cost benefit analysis to examine the optimization of the supplemental system. Results show that applying supplemental irrigation in case of low soil moisture during the critical stages of maize can have greater crop yield increments. Optimization of the system is achieved when a farmer sacrifices about 5% of his hectare piece of land to establish a runoff lined storage pond of 800 cubic meters by volume along with a diesel pump for water lifting using furrow irrigation. Using such volume of PVC lined pond covered with a natural mat of growing Azolla plant on the water surface can give optimum yields on a one hectare crop land. Azolla, the aquatic floating fern has multi benefits, however, its primary importance in this study is keeping the water pond environmentally safety. The proposed supplemental irrigation scheme has a payback period of 6 years.

This book was released on 2018-11-12 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Rice Research for Abiotic Stress Tolerance provides an important guide to recognizing, assessing and addressing the broad range of environmental factors that can inhibit rice yield. As a staple food for nearly half of the world's population, and in light of projected population growth, improving and increasing rice yield is imperative. This book presents current research on abiotic stresses including extreme temperature variance, drought, hypoxia, salinity, heavy metal, nutrient deficiency and toxicity stresses. Going further, it identifies a variety of approaches to alleviate the damaging effects and improving the stress tolerance of rice. Advances in Rice Research for Abiotic Stress Tolerance provides an important reference for those ensuring optimal yields from this globally important food crop. - Covers aspects of abiotic stress, from research, history, practical field problems faced by rice, and the possible remedies to the adverse effects of abiotic stresses - Provides practical insights into a wide range of management and crop improvement practices - Presents a valuable, single-volume sourcebook for rice scientists dealing with agronomy, physiology, molecular biology and biotechnology

Book excerpt: Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development.

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.
