 Any effort to eradicate hunger and malnutrition begins with making sure food systems provide a variety of healthy foods that are accessible and affordable to all consumers, including the most vulnerable. Food systems should also provide equitable income opportunities and have neutral or positive impact on the environment. Small and medium-sized enterprises, SMEs, make up the bulk of agri-food businesses worldwide. Representing a significant part of all formal agri-businesses and more than half of their full-time workforces. Yet, there's still little awareness of the role SMEs can play in making food systems supportive of healthy diets and nutrition. FAO supports SMEs on many fronts globally and locally to improve their contribution to sustainable food systems and healthy diets. In Ghana, Kenya and Vietnam, FAO and its local partners have introduced mentoring programs for local enterprises, seeking to boost skills and competencies so they perform better in local markets. FAO and its public sector partners are also working to create the conditions needed for SMEs to contribute to healthy diets. This includes working with local universities to mainstream nutrition into academic curricula for both agriculture and nutrition professionals. FAO is also developing e-learning courses for professionals and policymakers working with SMEs, introducing tools and innovative approaches to the role of SMEs in food systems. Nutrition is a worthy investment towards sustainable development and SMEs can make the difference in breaking the intergenerational cycle of poverty and malnutrition.
