Farming Goes High-Tech in the Amazon

Eco Ola has nine hectares of land, on which they are using sustainable farming techniques like polycultures (using more than one plant species in the same area), alley cropping (growing an agricultural crop simultaneously with a long-term tree crop to provide annual income while the tree crop matures), and rotating crops.

Permaculture: a path toward a more sustainable Amazon?

Eco Ola, a Peru-based organization founded by William Park and Carla Noain, has developed a community training center in the Peruvian Amazon to train people to learn how to improve soil in a polyculture/agroforestry system. Permaculture essentially mimics the form and structure of a natural forest, with a diverse array of species including a canopy of timber and fruit trees; an understory of cacao, bananas and species; and a shrub layer of herbs, legumes, and peppers.
