Insect farming, particularly Black Soldier Fly (BSF) farming, is an emerging and ecologically friendly agricultural opportunity in sub-Saharan Africa, with a focus on Malawi. A recent study aimed to assess the economic viability of BSF farming at different scales by conducting Cost-Benefit Analysis (CBA) based on data from a small-scale BSF farm in Lilongwe. The study addressed several critical questions: (a) What are the costs and benefits associated with BSF farming in Malawi for small-scale operations (individual farmers, clubs, cooperatives) and large-scale commercial farming? (b) What factors influence the benefit/cost ratio (BCR) of BSF farming across various production scales? (c) How can policies be developed to enhance BCRs and encourage BSF farming adoption in Malawi? Using economic indicators like Net Present Value (NPV) and Benefit Cost Ratio, the study found that BSF farming is economically viable at different scales of production. Small-scale farmers can generate approximately MK507,100 in gross revenue for one BSF larval cycle and MK2,535,500 annually. Meanwhile, commercial farmers can expect MK1,536,100 per larval cycle and MK7,680,750 annually. Even with a 10% variation in production costs, output prices, and BSF yield, sensitivity analysis demonstrated the continued profitability of BSF farming. This research fills a knowledge gap regarding the potential of BSF farming in Malawi. The findings provide a strong case for its development, which has been relatively overlooked in the country. Recommendations include investing in farmer and extension worker education, raising awareness about the socio-economic and ecological benefits, providing access to capital, supporting research and development, and establishing a regulatory framework to ensure the safe and effective use of insects as animal and aquaculture feed. These insights can inform government and stakeholder strategies, potentially revolutionizing agriculture in Malawi while promoting sustainable and innovative alternatives like BSF farming.
