Complex agroforestry systems and conservation of biological diversity (II)

As far as environmental impact is concerned, large-scale development of complex agroforests as those developed by peasants in Indonesia appears highly desirable. However, their productivity, in terms of cash income per unit of land, is still low and irregular. Complex agroforestry systems can no lon...

The increased profitability of complex agroforestry systems achieved by this new output could promote their spread leading to both economic development and environmental conservation.2013-09-18T04:14:06Z2013-09-18T04:14:06Z1992Journal ContributionArticleNon-RefereedMalayan Nature Journal (Malaysia), 45 (1-4), p. 488-500http://agris.upm.edu.my:8080/dspace/handle/0/4822MY9205324en
