Preface

Food is a basic necessity and thus everyone should have access to adequate amounts of safe and high-quality food. The concept of food security is of utmost importance for both developed and developing nations. Food availability, access, utilization, and stability are the pillars of food security. Today, these pillars are being negatively affected by natural disasters, poor agricultural and post-harvest practices, climate change, and poor manufacturing and marketing strategies. Food insecurity results in fear of hunger and starvation as well as in various chronic diseases due to reduced immunity, which in turn increases the economic burden on countries worldwide. This book discusses the challenges of food insecurity and their effects on quality of life, the environment, and more. It also discusses alternative means of food production and the development of genetically modified food to combat food security challenges. Finally, the book presents new trends and future prospectives.
