Date Time Tanzanian farmers boost diets, mental health with sustainable methods An innovative practice of farmers mentoring farmers on sustainable agricultural methods, nutrition and social equity has been proven beneficial in improving children’s diets and decreasing food insecurity in a region of Tanzania where nearly half of households fail to meet minimum nutrition requirements. It also reduced depression among women. Anthropologists and nutritionists from Northwestern, Cornell University and Nelson Mandela African Institution of Science and Technology conducted a groundbreaking study that demonstrated that farmer-to-farmer training can boost nutrition and well-being. Focused on smallholder farmers with young children, the program centered on farmers training other farmers on what they considered to be best practices. External inputs were limited to providing enough legume seeds for 0.25 acres twice during the three-year project.
