The 2017 edition of *The State of Food Security and Nutrition in the World* highlights the challenges and progress in achieving global food security and nutrition goals. Key messages include: 1. **World Hunger and Food Insecurity**: After a prolonged decline, global hunger appears to be on the rise again, with an estimated 815 million people undernourished in 2016. The prevalence of undernourishment increased to 11% in 2016, though it remains below the level of a decade ago. However, this recent increase is concerning and poses a significant challenge to international commitments to end hunger by 2030. 2. **Child Undernutrition and Overweight**: While child undernutrition continues to decline, levels of overweight are increasing. There are still 155 million stunted children under five, and adult obesity rates are rising in all regions. 3. **2030 Agenda for Sustainable Development**: The report marks the start of a new era in monitoring progress towards achieving a world without hunger and malnutrition. It includes thematic analyses of how food security and nutrition are related to other Sustainable Development Goals (SDGs), particularly SDG 2 (end hunger, achieve food security and improved nutrition, and promote sustainable agriculture) and SDG 16 (secure peaceful and inclusive societies). 4. **Conflict and Food Security**: The report emphasizes the nexus between conflict, food security, and nutrition. It shows how conflict affects food security and how food insecurity can trigger conflict. Over the past decade, conflicts have increased significantly, hitting rural communities hard. Conflict-driven food insecurity has led to widespread displacement and economic slowdowns, affecting food availability and access. 5. **Methodological Notes and Data Sources**: The report provides methodological notes and data sources, including the Food Insecurity Experience Scale (FIES), which measures people's ability to access food. The FIES is a new tool that complements the traditional indicator of undernourishment (PoU). 6. **Key Messages and Recommendations**: The report concludes with key messages and recommendations, emphasizing the need for sustained commitment and efforts to promote adequate availability and access to nutritious food. It calls for integrated policy approaches and actions to address the underlying causes of food insecurity and malnutrition. The report is jointly prepared by the Food and Agriculture Organization of the United Nations (FAO), the International Fund for Agricultural Development (IFAD), the United Nations Children's Fund (UNICEF), the World Food Programme (WFP), and the World Health Organization (WHO).The 2017 edition of *The State of Food Security and Nutrition in the World* highlights the challenges and progress in achieving global food security and nutrition goals.
