This book tackles the issue of using crop rotation to increase food production and secure it for the growing population of the future.  Crop rotation can be a solution of food gaps in the developing counties. Crop rotation plays an important role in attaining soil sustainability and in controlling pests and weeds.  It can alleviate damage caused by climate change by reducing losses in productivity of the crops, minimizing soil fertility loss and increase irrigation water productivity.  This book also includes the reviews of a large number of crop rotations that have been published internationally, and additionally, the crop rotations that have been implemented in Egypt have a unique characteristic to them and therefore, a large number of those reviews have also been included.

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?

This book will appeal to students and researchers involved with water scarcity and food security.
