Thailand leads the way, one bug at a time
Researchers say Thailand is showing the world how to respond to the global food crisis: by raising bugs for eating.
The United Nations' Food and Agricultural Organisation has released a study and handbook on what it calls "six-legged livestock" - edible bugs and worms that can help meet global food demand that is expected to grow 60 percent by 2050.
The agency said the bugs provide a rich source of protein, vitamins and minerals.
The study was conducted in Thailand, where insects including crickets, grasshoppers and bamboo worms have long been a part of diets, especially in rural areas.
Entomologist Yupa Hanboonsong said about 200 insect species were eaten in Thailand. Cricket farming alone was already a US$30 million industry there, but only a few other species have been commercially marketed.
