The document discusses challenges in linking livestock value chains to nutritional status in Nairobi, Kenya. It notes that while introducing dairy/meat production could improve producers' diets, underdeveloped value chains constrain this. It proposes researching how value chain weaknesses relate to low animal-sourced food consumption and poor nutrition. Key challenges include measuring transaction costs households face in accessing different value chains and relating these costs and retail prices to variation in nutritional outcomes. Addressing these challenges could help identify ways to improve value chains and target interventions.
