INSECTS
PROTEIN FOR A SUSTAINABLE FUTURE
Malnutrition in Uganda
In Uganda, livestock ownership is significantly associated with a lower prevalence of stunting in children making it a visibly beneficial path to reducing malnutrition (Mosites et al.). Household livestock ownership is classified as ownership of sheep, goats, cattle, and chickens. While livestock ownership can come with other challenges such as exposure to fecal matter and zoonotic pathogens, most families who own chickens, sheep, goats, or cattle greatly benefit from the direct source of protein in the meat, milk, and eggs, compared to families who do not own any livestock. Poverty in Uganda is primarily seen in rural areas, where families have to ability to keep small amounts of livestock with the proper resources.
For those Ugandan families who own chickens, finding adequate feed can be difficult and cost prohibitive due to spoilage of commercially available feeds. The Cal Poly Insects Group is proposing mealworm breeding as a low cost, self-sustaining method of producing protein-rich chicken feed at the ground level for rural impoverished Ugandans. We hope to design a low cost and easy to maintain mealworm breeding bin that is financially accessible to low income, livestock owning families in Uganda for supplementary use as chicken feed. Increasing the protein levels in chickens' feed will work from the bottom up to benefit the nutrition of the whole family, and creating a self-sustaining method of feed production via mealworm breeding will cut feed purchasing costs for the chicken owners.
This graph shows the prevalence of underweight children which is the percentage of children under the age of 5 whose weight for age is more than two standard deviations below the median for the international reference population ages 0-59 months. The data are based on the WHO’s child growth standards released in 2006. Uganda ranks 14th worst in the world, with 10.5% of their qualifying population weighing more than two standard deviations below the international reference.
Potential Partners
We reached out to an individual working on the insects as a food source aspect of this organization but we did not receive a response. The next group to take over this project might have better luck so we left their mission statement below.
"icipe's mission is to help alleviate poverty, ensure food security and improve the overall health status of peoples of the tropics, by developing and extending management tools and strategies for harmful and useful arthropods, while preserving the natural resource base through research and capacity building.
The Centre's vision is to pioneer global science in entomology, to improve the well being and resilience of people and the environment to the challenges of a changing world, through innovative and applied research, alongside deep exploratory study, impact assessment, evaluation, and sustainable capacity building."
Dr. Schwartz is a Cal Poly BRAE department professor. He received both his M.S. and Doctorate in Biosystems Engineering with a concentration in aquaculture and wastewater engineering from Clemson University. Before coming back to Cal Poly to teach, he worked for Kent BioEnergy, an aquaculture company in Mecca, CA for 11 years. For the last couple of years, Dr. Schwartz has tried multiple systems for raising mealworms. In those years he has used a two-tray system, a four-tray system, and a single tray system. He has offered to be a contact and resource for next quarter's team and he has a place in his lab to construct a model. He is interested in looking into different ways to maximize output so he can feed the fish in his aquaponics system.

RVI produces and distributes insects and other organisms, supplies, and tools for biological control of pests. We are pioneers in the use of natural enemies in ecologically based pest management. They would be happy to be listed as a resource. Most of their experience is with houseflies. They have only dabbled in black soldier flies and they tried raising mealworms on styrofoam and stopped due to a question about feed-through styrene in the mealworms. They recommended doing a parallel rearing trial in future quarters and it would fit with the interest of one of our interns.

Aid Africa is working collaboratively with an army of organizations to bring help and hope to the poorest of the poor in Uganda, with a vision to rebuild 1,000 sustainable communities by providing clean water, efficient, cleaner burning stoves, farming and reforestation, and other household necessities. Peter Keller would be a great resource for implementing our model in Uganda after several trials have been done at Cal Poly to figure out the best model.

Other Approaches
Insect breeding for direct human consumption is another way to provide low cost nutrition to protein deficient families. This approach comes with added challenges like issues with sanitation and disease and how to overcome the "ick" factor. In many places bugs are an accepted food source, so the latter may be less of an issue. The largest problem comes with sanitation and disease. Bugs, like other consumables, can carry and transmit diseases to those who eat them. Because they are small and must be eaten whole, it can be difficult to fully clean them before consuming. It is possible that proper preparation and cooking could be the solution to this issue, but more research would need to be done on human insect consumption before we could recommend this as a useful solution for malnutrition in Uganda.
