Why the world's fourth most important staple relies on Andean diversity

Science Bulletins: Potato Biodiversity—Ensuring the Future · 8:57 · Video: American Museum of Natural History · Watch at the source

In short: The potato is a global culinary cornerstone, but its future depends on the ancient farming practices of the Andes. This video explores how preserving thousands of local varieties acts as a vital insurance policy against a changing climate.

While the potato is a dominant global crop, its resilience is rooted in the biodiversity of its native Andean home. Farmers in this region cultivate thousands of distinct varieties, a practice supported by the International Potato Center in Lima.

This genetic diversity is not just a matter of heritage; it is a strategic defense. By maintaining a wide array of potato types, these communities protect the global food supply against escalating threats, including pests, diseases, and extreme weather patterns caused by climate change.
