Preface to Transitioning to Zero Hunger by Delwendé Innocent KibaFood insecurity remains a global concern, with challenges exacerbated by social and health crises, namely the COVID-19 pandemic and geopolitical conflicts. Experts agree that food security requires coordinated efforts for a transition to zero hunger. Despite technological advances, agrifood systems still face significant hidden costs linked to environmental, social, and health problems. Efforts to address food security are aligned with the Sustainable Development Goals (SDGs) adopted in 2015, but the FAO estimates that nearly 670 million people will still suffer from hunger in 2030. This book explores the quest for a world with access to sufficient, safe, and nutritious food, focusing on the need for inclusive, resilient, and sustainable agrifood systems. It analyzes the drivers of hunger and the sustainability of food production, offering pathways for a transition to zero hunger. The chapters examine the links between SDG 2 and the other SDGs, the role of social capital, and agroecology, presenting case studies on agroforestry, agrobiodiversity, yam farming in West Africa, livestock farming integrated with coconut production in Sri Lanka, and approaches to limit food waste.
