Zambia’s insect eating tradition may aid food security

A study from the University of the Witwatersrand suggests that reviving the tradition of eating insects in rural Zambia could strengthen household food security, though its success depends on broader acceptance.

Researchers surveyed 139 households in Zambia’s Central province and found that insects play a role in local diets and nutrition. However, the practice, known as entomophagy, has declined, particularly among younger generations.

The study highlights that while insects could support sustainable food systems, they remain underused in mainstream diets and economies, limiting their potential benefits for livelihoods and wellbeing.

In Zambia, higher education levels correlated with greater insect consumption, indicating that informed community leaders might help promote the nutritional and economic value of entomophagy.

Overcoming barriers

Jasper Knight, a co-author, proposed integrating entomophagy into existing public health programs, such as maternal care or school education, to encourage adoption. He noted that insects are a free, nutritious food source that can enhance food security and supplement incomes.

The researchers advocate for small-scale insect farming to ensure sustainability and local economic benefits. Large-scale commercialization, they warn, could exclude rural communities from the advantages.

Arnold van Huis, an entomophagy expert from Wageningen University, argued that commercialization is essential for the practice to survive. He acknowledged challenges, including the need for more research into farming methods for species like caterpillars and termites.
