Food production successively moved towards higher altitudes, where the more profitable sugar cane would not be cost-effective. In places where dry—stone walls were built, all remains of the trees that grew there had to be removed before wall building started. Consequently, the practice parra adding organic material from com the terraced area has disappeared, too.
