**Bonn, Germany** – A groundbreaking study published in *Nature Food* challenges the long-held belief that increased crop diversity on individual farms is the primary solution to nutritional deficiencies in Africa. Researchers from the Center for Development Research (ZEF) at the University of Bonn analyzed data from nearly 90,000 households across six African nations (Ethiopia, Malawi, Niger, Nigeria, Tanzania, and Uganda) between 2008 and 2022. Their findings reveal that improved access to markets plays a significantly more crucial role in achieving dietary diversity and combating undernutrition than previously thought.

The study, which utilized household dietary diversity scores (HDDS) to assess nutritional intake, found that while farm-level crop diversity had a positive, albeit minor, impact, access to markets was far more influential. Professor Matin Qaim of ZEF explained that regional crop diversity, facilitated by better roads and market infrastructure, can effectively substitute for individual farm diversification. This is significant because encouraging regional production and market distribution is more practical than pushing every smallholder farmer to cultivate a wider range of crops.

The research highlighted several key factors:

* **Market access:** Improved infrastructure, such as better roads, significantly improves household dietary diversity by allowing farmers to sell surpluses and purchase foods they lack. The study noted the negative impact of distance from urban centers, with the average household located approximately 31km away.
* **Climate shocks:** Droughts, floods, and other extreme weather events negatively impact household dietary diversity.
* **Cash crops:** Production of non-food cash crops, such as cotton or coffee, can positively influence dietary diversity through increased income.

The study also emphasizes the need for further research into the impact of climate shocks on nutritional resilience and the optimal balance between local production and market reliance. While acknowledging the importance of farm-level diversity, researchers advocate for prioritizing infrastructure improvements to facilitate market access as a more effective strategy for tackling undernutrition. Current initiatives, such as the UNOPS feeder roads project in South Sudan, exemplify efforts to address this critical infrastructure gap. The researchers concluded that optimizing agricultural practices to suit local conditions and maximizing market access are key to improving nutritional outcomes across the continent.
