In this episode, you will listen to Daniela Peguero, researcher at Eawag’s Department of Sanitation, Water and Solid Waste for Development (SANDEC), working on the implementation of black soldier fly farming in several African countries through projects such as BUGS Africa and SWIFT (Sustainable Waste-based Insect Farming Technologies).

We discussed practical field experiences from Uganda and Malawi, where black soldier fly larvae are used as a locally adapted protein source for livestock. Daniela explained how substrate availability — from pig manure to hotel food waste and invasive water hyacinth — influences the bioconversion process and operational decisions.

Among the topics we covered were feed costs, faster chicken growth when larvae partially replace imported feed, methane emissions linked to open dumping, and the importance of adapting insect farming systems to real environmental conditions.

Daniela also introduced the open-access Simba approach, developed to support small-scale farmers, and described the WhatsApp community created to facilitate peer-to-peer troubleshooting, matchmaking, and knowledge exchange across low- and middle-income contexts.

The conversation also touches on the upcoming Insects To Feed The World conference, where a dedicated session will focus on black soldier fly implementation in these regions.

My name is Umberto Diecinove. I am a documentary photographer and I am currently leading a project titled I N S C T S, which explores the potential role of insects in addressing environmental and social challenges. I do this by traveling and photographing research centers, farms, communities, and companies around the world, engaging with researchers and practitioners working in the field. I believe insects could represent an important part of future food and agricultural systems.
