World Edible Insect Day aims to raise awareness about sustainable and alternative forms of nutrition as the planet faces population growth, food insecurity, and environmental strain.
Among the most promising sources of sustainable protein are insects such as Mopani caterpillars and crickets, nutrient-dense solutions for the future of food.
Bohlale Mashego, Operations Manager at Matomani, believes that Mopani worms represent an environmentally and economically sustainable protein alternative.
They are incredibly nutritious and sustainable; rich in vitamins and minerals, explains Mashego.
Beyond their nutritional value, Mopani worms also play an important ecological role, contributing to nutrient cycling and serving as a natural food source for other animals.
Economically, they offer valuable income opportunities for rural communities where they are harvested, helping to drive local business growthand skills development.
As the global population increases, food systems are under pressure to produce enough protein without damaging the planet. Edible insects like Mopani caterpillars use far less land and water than traditional livestock, making them an important part of the conversation around sustainable diets and food security.
Across the globe, consumer attitudes are shifting, particularly among health-conscious and environmentally aware individuals. More people are beginning to embrace insect-based foods, especially when presented in familiar formats such as protein powders or snack bars.
