Feeding the world with an orchestra of crickets

Alex Figg, 23, who began an architecture degree and became an expert on insect farming, is one of three founders of Critter Farms, an enterprise raising an orchestra of crickets for food.

The final-year Masters of Architecture (Professional) student was researching sustainable architecture when he learnt the World Health Organisation had declared our current agricultural practices unsustainable.

According to the WHO, an estimated 9.3 billion people will require feeding by 2050, with protein being the nutrient in short supply.

While pondering how this would impact on future land use and architecture, Alex and co-founder Elliot Olsen began investigating alternative protein sources.

They discovered that crickets were a sustainable, efficient and nutritious protein source which far outperforms traditional livestock. The insects use 2000 times less water, 12 times less feed, and emit a hundred times fewer greenhouse gases compared to beef.

High in protein, essential salts, vitamins, minerals and omega 3 and 6 fatty acids, crickets are a super food of sorts.

While the global population grows and becomes increasingly urban, there will be less arable land available for agriculture.

“Crickets don’t require earth to be farmed, so they can potentially utilise vertical space which can be designed into buildings,” says Alex.

Alex, whose personal goal is to use truly sustainable practices in his life and work, has also been researching a new biodegradation method to recycle problem plastics, utilising advances in environmental science. The idea recently won a Velocity Innovation Challenge Prize worth $1,000.

Between plastic recycling and finishing his architecture degree, he and his Critter Farms colleagues are prototyping cricket farming in Auckland with the target of helping enable a paradigm shift away from our dependence on land for food.

About 2 billion people already eat insects to supplement protein.

Critter Farms crickets are toasted and ground into a nutty flavoured powder which can be used as a tasty, high protein food ingredient. “I recommend you try it,” says Alex.
