Natividad Colque proudly displays 17 varieties of native potatoes – wayku papa. Their many shapes and colours reflect meticulous selection based on characteristics that meet her family and community’s needs.

She selects potatoes that have plenty of nutrients; that use less cooking fuel; that sell well in local markets; and that resist frost and hail.

Before working with USC’s partner PRODII, Natividad’s fields had only the four commercial varieties introduced by government agents. These modern types did well the first couple of years, but quickly deteriorated by year three. And they were filled with water – good for French fries but not for growing children.

“My wayku papas,” Natividad insists, “have a more consistent yield and need only the natural materials from my farm to flourish.” Her fields of diversity also mean that at least some kinds will survive the unpredictable, ever-harsh weather of the highlands.
