This book reviews a wide-range of genetically modified (GM) crops to understand how they are produced, the impacts on the agricultural industry, and their potential for improving food security. The production of GM crops has now become an invaluable asset in the agricultural toolbox. With a significant portion of the world suffering from hunger and poverty, this book examines how food security can be achieved through GM crops. A wide variety of crops are examined, from the earliest developments of GM tomatoes and potatoes to recent interest in the development of low-cost, high yielding biofuels, such as microalgae. Chapters also discuss the role of GM crops in pest management and the consequential reduction in the use of insecticides. Overall, this book provides an important synthesis of GM crops from their commercial value to the agricultural industry, as well as their potential for improving food security. This book will be of great interest to students and scholars of agricultural engineering, crop science, food biotechology, food security, and those interested in food and agriculture and sustainable development more broadly.
