# Moving beyond forest cover: Linking forest density, age, and fragmentation to diet

## TL;DR

The study explores how specific forest characteristics like density, age, and fragmentation relate to children's diets in Kenya, finding that different forest types support different dietary benefits.

## Contribution

The paper introduces a nuanced analysis linking detailed forest characteristics to dietary outcomes, moving beyond simple measures of forest cover.

## Key findings

- Vegetable/fruit consumption was positively linked to open and moderately dense forests but negatively to fragmented ones.
- Younger forests were associated with higher meat and vitamin A-rich fruit consumption, while dense forests were not.
- Older forests were linked to more green leafy vegetable consumption but less of other vegetable/fruit types.

## Abstract

Forests support food security and nutrition worldwide, especially so for highly forest-dependent communities who collect a variety of food products from nearby forests. While the importance of forest cover to the diets of forest-dependent communities has been well-researched, little is known regarding the role of more specific forest characteristics – information that would be valuable for better identifying the landscapes that support a nutritious and diverse diet. To address this research gap, we linked child dietary data to remotely-sensed geospatial indicators of surrounding forest characteristics – using more nuance than is typically undertaken – by examining forest age, tree density, and forest fragmentation in Kenya’s East African Montane Forests. Interestingly, dietary diversity of children demonstrated no or relatively weak associations with forest characteristics. However, by parsing out individual food groups, we exposed the nuance and complexities associated with the forest-diet relationship. Vegetable/fruit consumption was positively associated with open and moderately dense forest cover, but negatively associated with fragmented forest cover. The consumption of meat and vitamin A-rich fruit was positively associated with younger forest cover, and negatively associated with dense forest cover. Older forest cover was positively associated with green leafy vegetable consumption, but negatively associated with other vegetable/fruit consumption. Our findings provide suggestive evidence that there is no single ‘ideal’ type of forest for supporting food security and nutrition – rather, different types of forests are associated with different dietary benefits. Taken together, these results indicate the need for more in-depth research that accounts for factors beyond the proximity and amount of generic forest cover.
