A new study reveals for the first-time substantial benefits from adopting smallholder aquaculture for Zambian farmers. The research, published in Agriculture & Food Security, provides compelling evidence of how fish farming diversifies livelihoods and improves food and nutrition security in rural areas.

“Showcasing the role of aquaculture to food and nutrition security of rural homesteads in Africa is a relatively difficult thing to prove. For the first time our study in northern Zambia shows that smallholder aquaculture can be a game-changer for local farmers,” said Alexander Kaminski, PhD researcher at the University of Stirling’s Institute of Aquaculture who undertook the research at WorldFish. “By integrating fish farming into their agricultural practices, households not only diversified their income sources but also significantly improved their dietary variety and overall food security.”

The research compared households with and without fishponds, demonstrating that those engaging in fish farming experienced a noticeable enhancement in their livelihoods. These benefits extended beyond mere income generation, leading to a richer, more nutritious diet and a more resilient agricultural system. The study found that adopting aquaculture gave households two time more likelihood to improve their food security status. 

Shakuntala Thilsted, CGIAR Director of Nutrition, Health and Food Security and WorldFish Global Lead for Nutrition and Public Health at the time of the research highlighted the implications of the findings. “This study provides clear evidence that fish farming is an invaluable component in the fight against food and nutrition insecurity in Africa. It provides evidence that nutrition-sensitive homestead aquaculture can enrich diets and create sustainable farming systems that benefit entire communities.”

The study’s results are significant, showing that food and nutrition security from aquaculture arrives via three pathways, farmers selling fish for money to afford a better diet, eating fish from ponds to have access to high-quality sources of protein and micronutrients, and using the pond within an integrated farming system that allows for diversification into other crops. 

The results of this study offer a path forward for policymakers and development agencies looking to improve rural economies and nutrition in developing regions. It underscores the value of looking beyond traditional agricultural methods and embracing more integrated, diversified farming approaches. The study recommends that while measuring productivity and profits from ponds is useful, measuring the impact on dietary quality and food security is equally important.
