 nutrition-related public-private partnerships, PPPs, have been proposed as a way to address malnutrition in countries around the world. However, these partnerships face numerous challenges, including a lack of understanding of the underlying causes of malnutrition, a weak architecture for global governance of nutrition, power imbalances between public and private sector actors, and disagreement among stakeholders about the role of the private sector in addressing malnutrition. As a result, PPPs are often ineffective at achieving their goals, due to goal ambiguity, resource imbalances, and weak accountability. To ensure successful implementation of PPPs, these challenges must be addressed through increased understanding of the root causes of malnutrition, improved global governance structures, greater collaboration between public and private sector actors, and a focus on evidence-based decision-making.
