This manual has been developed based on participatory workshops and subsequent agri-nutrition training courses in Vihiga County, Western Kenya by the Alliance of Bioversity International and CIAT. This manual was further evaluated in Turkana and Busia Counties in Kenya, with the intention to develop agricultural interventions to improve nutrition. The learning objectives for the training are focused on: (1) basic principles of nutrition; (2) a life-cycle approach to nutrition; (3) home gardening; (4) use of underutilized crops to diversify diets; and (5) a practical cooking demonstration session. By the end of the training, participants will be able to: 1. Identify various forms of malnutrition (underweight, wasting, stunting, overweight, and obesity) 2. Describe what makes a healthy diverse diet for women, children, and other family members 3. Appreciate the role of home food production in ensuring consumption of diverse diets 4. Appreciate the potential role of wild and underutilized plant species in increasing the diversity of diets to improve nutrition 5. Demonstrate practical skills in offering nutrition education, counselling, and cooking demonstrations in the community 6. Understand their role in promoting good nutrition practices in their communities
