Food Safety, Security and Environmental Sustainability is a comprehensive, multidisciplinary volume that explores the interconnected dimensions of modern food systems and their implications for human health, nutrition, livelihoods, and the environment. The book examines how climate change, population growth, urbanization, globalization, technological advancement, and changing dietary patterns are reshaping food production, distribution, consumption, and governance.

The book provides an in-depth discussion of food safety challenges, including biological, chemical, and emerging contaminants, food fraud and adulteration, supply-chain vulnerabilities, cold-chain limitations, and socio-economic barriers. It also highlights the role of emerging technologies such as the Internet of Things (IoT), blockchain, artificial intelligence, big data analytics, smart packaging, genomics, and advanced traceability systems in improving food safety, transparency, and resilience.

A significant focus is placed on food security and environmental sustainability, covering climate-smart agriculture, water management, agroforestry, organic farming, permaculture, climate-resilient crops, regenerative agriculture, and the integration of economic, social, and environmental considerations. The book further examines nutritional transitions, dietary changes, malnutrition, non-communicable diseases, and policy approaches for promoting healthier and more equitable food systems.

The volume also presents discussions on food-system governance, policies, laws, international commitments, implementation pathways, and case studies from Africa, Asia, and Latin America. These perspectives offer practical insights into nutrition-sensitive agriculture, urban food safety, school feeding systems, digital innovation, sustainability, equity, climate resilience, and capacity building.

This book will be a valuable reference for students, researchers, academicians, policymakers, food technologists, nutritionists, agricultural professionals, environmental scientists, and industry practitioners seeking a deeper understanding of the challenges and opportunities involved in developing safer, healthier, sustainable, and resilient global food systems.
