How are Peruvian indigenous highland communities promoting agrobiodiversity?

Video - Indigenous highland communities in the Peruvian Andes sustain one of the most diverse food systems in the world. Using specially-adapted farming techniques, they conserve some of the world’s most important agrobiodiversity crops that could be key to food security in a warming and more unpredictable climate. CGTN’s Dan Collyns visited communities in the highlands of Cusco that cultivate dozens of varieties of maize, or corn – the cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago.
