The Benefits of Insect Farming

Insect farming presents a compelling solution to global challenges in food security, sustainability, and circular resource use. Its benefits span environmental, economic, and nutritional dimensions.

High Feed Conversion Efficiency

Insects are highly efficient at converting feed into protein. For example, crickets require six times less feed than cattle, four times less than sheep, and about half as much as pigs or poultry to produce equivalent protein. This makes them an ideal protein source where resource use is a concern.

Low Environmental Impact

Compared to traditional livestock, insect farming uses up to 90% less land and produces approximately 100 times less CO₂ emissions. It also requires minimal water and can reduce landfill methane emissions by upcycling organic waste into biomass.

Circular Economy Potential

Insects thrive on agricultural byproducts, food scraps, and other organic waste, converting them into valuable protein and byproducts like frass, a nutrient-rich fertilizer. This contributes to waste reduction and resource circularity across agriculture and food systems.

Rapid Growth and Scalability

Many insect species grow quickly and can be reared in controlled, vertically integrated systems, allowing for year-round production and efficient use of space—especially important in urban and resource-constrained regions.

Nutritional Value

Insects offer a complete nutritional profile, including high-quality protein, essential amino acids, healthy fats, and micronutrients like iron and zinc. This makes them suitable for both human diets and animal feeds, including aquaculture and pet food.

Economic and Social Benefits

Insect farming generates income opportunities for smallholders and entrepreneurs, particularly in the Global South. It can empower women, youth, and marginalized communities by offering low-barrier entry into sustainable agriculture. In Africa and Asia, it is increasingly viewed as a solution for poverty reduction and food insecurity.
