Two articles about the contrasting fortunes of Andean crops came out last week. They describe different sides of the same broad story: Indigenous agricultural systems are highly biodiverse and increasingly positioned as climate adaptation strategies, but they are also under pressure.

In Peru, potato farmers in places like the Parque de la Papa are actively conserving thousands of native potato varieties as a form of insurance. This is climate change adaptation: maintaining agrobiodiversity, preserving traditional knowledge, and using resilient crop varieties and farming practices to buffer against warming temperatures, erratic rainfall, and pest and disease pressure. The message is that crop diversity itself is a survival strategy, both ecological and cultural.

The recent history of quinoa in Bolivia shows the same system under a different kind of stress: global demand drove a commodity boom that incentivized monoculture expansion and mechanization, which in turn contributed to soil degradation, erosion and reduced resilience. Coming back from that is proving difficult.

Together, the two cases show that when Indigenous agroecosystems are treated as living repositories of diversity, they can enhance resilience, including to climate change; and that when they are pulled into boom-driven export specialization, that resilience can be undermined. The shared lesson, at least for me, is that climate adaptation in mountain agriculture depends on maintaining ecological and genetic diversity embedded in Indigenous land management systems.

A point that I suspect is highlighted in the book Andean Potatoes and Quinoa: Origin, Current Status and Recipes of Ancestral Crops, also recently announced.
