This book tackles the issue of using crop rotation to increase food production and secure it for the growing population of the future.

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.

The book includes some insights on the implications of using climate-smart practices in irrigated and rain-fed agriculture, and suggests approaches to eradicate the negative effects of water scarcity, climate variability and climate change.

The world population is steadily increases with high rate in the past decade from 7,126 billion inhibitors in 2012 to 8,095 billion inhibitors in 2024, with 14% increase. In the meantime, the number of severely food insecure people were 604.5 million in 2014, which increased by 53% in 2020 to reach 927.6 million people. These numbers raise large concerns about the future of food production to feed these continually growing population. Lately, many developing countries rely on importing large quantities of crops, such as wheat, maize, and rice to meet their food and feed needs. The negative impact of climate change and its consequences, namely high temperature causing low crops productivity and water scarcity, which causing great disruptions in food production systems. Therefore, increasing the production of cereal crops worldwide can be achieved through increasing average yield per unit area or expanding the area devoted to cereals into more marginal lands. Moreover, breeding for more resilient cultivars, which can release its potential yield could play an important role in increasing total production under the adverse growth conditions.Inclusion of legume crops, such as soybean, peanut, and cowpea in cereal-based cropping systems is a viable strategy to increase production of cereal crops. It also helps in reducing the use of chemical fertilizer. It has been reported that intercropping legume crops with cereal crops can increase the productivity of both crops. Additionally, an increase in soil nitrogen, phosphorus and potassium has been also reported when legume crops were included in cereal-based cropping system. It has been also reported that inclusion of legume crops increases the soil water-holding capacity and water used efficiency. Thus, inclusion of legume crops in cereal-based cropping systems can increase its productivity, as well as attains the sustainable use of soil and water resources.In this book, we will thoroughly tackle the benefits of the integration of legume crops within cereal-based cropping system, namely wheat, maize and rice (paddy and upland) under the changing climate (current and future). We also reviewed the innovations and interventions that could sustainably intensify the production of cereals to reduce hunger and poverty. We will use both modeling and simulation approaches to assess the impact of climate change using CMIP6 mean projection of two future scenarios, namely SSP1-2.6 and SSP5-8.5 in two time-intervals (2060-2079 and 2080-2099) on the yield and water requirements of wheat, maize and rice (paddy and upland).

The book contains suggestion on suitable crop rotations for salt-affected soils to maximize the productivity of lands and water under current climate and under climate change in 2030. This book discusses droughts and water scarcity, which are important issues related to natural phenomena and affected by climate variability and change. It calls for reassessing the prevailing crop structure in Egypt under rain fed irrigation in North Egypt and under surface irrigation in the Nile Delta and Valley.Droughts affect rain fed agriculture, while water scarcity affects irrigated agriculture. The book investigates proposals for improving crop structure in these areas, taking into account the sustainability of water and soil resources. Further, it explores improved management options for crop production in both rain fed and irrigated agriculture. Lastly, it examines suggestions on more rational use of irrigation water in irrigated agriculture to conserve irrigationwater under present climate conditions and to help meet the anticipated demand under climate change conditions.

This work gives a multidisciplinary approach to assess and provide solutions to improve food security in Egypt. It has specific chapters on projection of climate change using IPCC AR5 models and regional climate model, and a chapter on population projection in 2030.

This book provides state-of-the art analysis, never done before in Egypt, on agro-climatic zones level. This study deals with how the national cropping pattern can be modified to overcome abiotic stresses, such as water scarcity, induced salinity and climate change to reduce their negative effects on food production. To this end, different cropping patterns are suggested. This study can be a framework for other developing countries to be used in quantifying and filling the gap in their knowledge about practices that can help in increasing their food security through increasing food production. Furthermore, the study is useful for policy makers to help them in their future plans and policies.
