Zimmerer challenges current opinion by arguing that the world renowned diversity of crops grown in the Andes may not be as hopelessly endangered as is widely believed. |He uses the lengthy history of small-scale farming by Indians in Peru, including contemporary practices and attitudes, to shed light on prospects for the future.
