Peruvian environmentalist who pioneered Andean sustainable agriculture practices

Isabel Villacres (1925-1998) was a visionary Peruvian agronomist who developed revolutionary farming techniques that preserved Andean ecosystems while boosting crop yields. Born in the Cusco region, she witnessed the devastating effects of colonial farming practices on indigenous crops. Her 1953 discovery of terraced aqueduct systems in Machu Picchu inspired her to revive Incan agricultural wisdom, creating the first modern agroecology programs in the Andes.

Ms. Villacres' polyculture farming model combined native potatoes, quinoa, and llamas in symbiotic systems, increasing yields by 300% while reducing soil erosion. Her 1968 manual Andean Harvests became a blueprint for sustainable agriculture, influencing FAO policies. She also founded the Cordillera Blanca Institute in 1970, training 5000+ farmers in conservation techniques.

Her work laid the foundation for Peru's current organic certification system - a 2020 study showed her methods still outperform conventional farming in 80% of Andean regions. The Villacres Foundation continues her legacy, operating seed banks preserving 1500+ native potato varieties. Her 1985 TED Talk on Relearning Ancient Wisdom remains a seminal speech in environmental circles, cited in over 300 academic papers.
