The WHO describes knowledge networks as a mechanism to strengthen collaboration among countries and facilitate and enhance local nutrition action in the Nutrition Decade. In line with this recommendation, the NNEdPro Global Centre convened 12 Regional Networks across six continents to foster collaboration and implement nutrition actions for sustained impact. Each network has a lead who connects the broader NNEdPro group to the local network to share evidence and encourage collaboration within and between Networks. Each Network is encouraged to understand the needs of their region, locally tailor relevant interventions, and share learnings with other networks. The focus of these networks is on knowledge exchange, capacity building among members, and wider public health impact. An example of these networks in action is the use of the Mobile Teaching Kitchen (MTK) model, which empowers marginalised community members to become culinary health educators. The intervention was originally developed by the Regional Network in India, and adaptations of the MTK intervention are planned across the Swiss, Mexico, Italy & The Mediterranean, and the Brazil Regional Networks. Networks will learn from each other while making adaptation relevant to their local need, resources, and capacity. Knowledge networks underpinned by strong leadership and clear communication strategies are essential to take collaborative action on nutrition and end malnutrition in all its forms.
