We are no longer updating the Research Digest. All content remains.
The Permaculture Research Digest has summaries of newly published permaculture-related research. All items are hyper-linked to the original publication.
The 'January 2013' archive contains 60 items published in 2012.
Items marked with a # have restricted public access, although abstracts are freely available.
Shifting agriculture in the tropics has
been replaced by sedentary smallholder farming on
degraded land. To address low yields and low income both, the soil
fertility, the agroecosystem functions, and the source of income can be
restored by diversification with nitrogen-fixing trees and the
cultivation of indigenous tree species. Biodiversity studies indicate that
mature cash crop systems, such as cacao and coffee with shade trees,
provide wildlife habitat that supports natural predators. This review offers
suggestions on how to examine these agroecological processes in more
detail for the most effective rehabilitation of degraded land.
