Download or read book Simulation of the Effect of Water Conservation on Crops in Egypt written by Samiha Ouda and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yield-Stress model employed soil water depletion equations to instantly predict potential yield of 10 summer and winter crops under varying degree of water and salinity stresses in Egypt. Studying the depletion of soil water from the root zone was used in irrigation scheduling to save on the applied irrigation water to these crops. The model prediction showed good agreement between measured and predicted yield and water consumptive use values, which implied that the model is capable of investigating alternatives deficit water irrigation, saline water irrigation and/or deficit saline water irrigation.The use of the model could partially replacing expensive field experiments. The ability of Yield-Stress model to simulate the effect of water and salinity stresses provide an appropriate irrigation management tool to maximize yield and to save irrigation water.
Download or read book Major Crops and Water Scarcity in Egypt written by Samiha Ouda and published by Springer. This book was released on 2015-08-24 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book includes multi-disciplinary quantifications of the effect of climate change on water requirements of wheat, maize, rice and sugarcane. Furthermore, it provides on-farm management that faces water scarcity under current situation and under climate change. Changing cultivation method (raised beds instead of furrows or basins) or increasing irrigation application efficiency (sprinkler or drip systems instead of surface irrigation) can reduce the applied water. Irrigated agriculture, although profitable, it endures wasteful use of valuable water resources. Taking into account the risk of climate change, developing countries like Egypt will highly suffer. Furthermore, the effect of intercropping (two crops use the applied water to one of them), and/or using crop rotations (arrange crops to reduce the applied water, increase water productivity and sustain soil fertility) on production and consumed irrigation water by crops were comprehensively analyzed.

Available in PDF, EPUB and Kindle. Book excerpt: This report aims to synthesize the results of a crop water use study conducted by country teams of the GEF/World Bank project, Regional Climate, Water, and Agriculture: Impacts on and Adaptation of Agro-ecological Systems in Africa. It also presents the results of the second phase of the study based on climate change scenarios, conducted by the South Africa country team. The actual evapotranspiration of five commonly grown crops-maize, millet, sorghum, groundnuts, and beans-in two selected districts were analyzed by six country teams. In addition, two country teams also analyzed other crops grown in the districts. The regional analysis shows that the actual yield of the different crops-specifically of maize and groundnuts-improves with an increase in actual evapotranspiration, although the gap remains wide between actual and potential yield and actual and maximum evapotranspiration, especially for the rainfed crops. This highlights the importance of improved water management if agriculture is to play an important role as a source of food security and better livelihoods. The report highlights the vulnerability of maize to water stress and the increased risks to the viability of rainfed farming systems based on this crop. The results of the second phase of analysis show that a 2°C increase in the temperature and a doubling of carbon dioxide concentration in the atmosphere will shorten the growing period of maize, which will result in decreased crop water requirement and use. The authors recommend extending this type of analysis to other crops as well as to other countries to develop a clearer picture of the changing pattern in crop water use of the major crops grown in the project countries.

Download or read book Deficit Irrigation written by Samiha Ouda and published by Springer. This book was released on 2021-01-23 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on proving that deficit irrigation could play an important role in increasing food production in times of water scarcity. Although the application of deficit irrigation can involve loss in crop productivity, it still secures water to be use in cultivating more lands and producing more food. The following questions are discussed and the authors offer solutions to these problems: Will the production, on a national level, resulting from these new added areas compensate yield losses attained by application of deficit irrigation? Is it possible to use deficit irrigation practice to reduce the applied irrigation water to certain crops that have a surplus in their production, and direct this saved water to cultivate new areas with crops have low self-sufficiency ratios? Under climate change in 2030, would deficit irrigation practice have the same role it plays under the current conditions? This book will appeal to students and researchers involved with water scarcity and food security.

Download or read book Unsaturated zone Modeling written by R.A. Feddes and published by Springer Science & Business Media. This book was released on 2004-10-11 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mankind has manipulated the quantity and quality of soil water for millennia. Food production was massively increased through fertilization, irrigation and drainage. But malpractice also caused degradation of immense areas of once fertile land, rendering it totally unproductive for many generations. In populated areas, the pollutant load ever more often exceeds the soil’s capacity for buffering and retention, and large volumes of potable groundwater have been polluted or are threatened to be polluted in the foreseeable future. In the past decades, the role of soil water in climate patterns has been recognized but not yet fully understood. The soil-science community responded to this diversity of issues by developing numerical models to simulate the behavior of water and solutes in soils. These models helped improve our understanding of unsaturated-zone processes and develop sustainable land-management practices. Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress in soil-water modeling. Top scientists present case studies, overviews and analyses of strengths, weaknesses, opportunities and threats related to soil-water modeling. The contributions cover a wide range of spatial scales, and discuss fundamental aspects of unsaturated-zone modeling as well as issues related to the application of models to real-world problems.

Available in PDF, EPUB and Kindle. Book excerpt: Global climate change is one of the most important environmental issues facing the world today. The United Nations Framework Convention on Climate Change (FCCC) acknowledges the potential for global climate change to have major effects on the world economy. The work of the Intergovernmental Panel on Cli mate Change (lPCC) is focused on evaluating the scientific data on climate change and analyzing the potential responses to it. One of the primary issues in the global climate change debate is how to adapt to any change that might occur. The process ofidentifying adaptation measures and evaluating their effectiveness is the focus of this book. In dealing with climate change adaptation, the sequence of events in conduct ing these types of analyses can be generalized as follows: • Develop scenarios for the possible range of climate change, • Assess the vulnerability of various sectors of the national economy and infrastructure to climate change, and • Identify and evaluate measures in each sector to adapt to the climate change It is this third step that is the subject of this book. In presenting this material, Chapter 1 gives an overview of the concept of climate change adaptation and the general principles guiding the conduct of analyses in this area. Chapters 2-7 give the results of evaluating climate change adaptation options in the agriculture, water resources, coastal resources, forest and ecosystems, fisheries, and human settlements sectors.
