Shifting from simple to complex agroforestry systems: an example for buffer zone management from Kerinci (Sumatra, Indonesia)

摘要

Kerinci is a densely populated valley surrounded by a national park in western central Sumatra, Indonesia. Indigenous agroforestry systems include important cash crops like coffee (Coffea canephoravar.robusta) and cinnamon (Cinnamomum burmani), and range from alternate cycles of cash crop monocultures or simple associations, to multispecies and multi-storey gardens; these may include as many as 100 common useful species, comprising many fruit trees and indigenous timber species.
