Polyculture and monoculture: Contrast and analysis

Although polyculture or interplanting is a dominant production method used by traditional cultivators in the tropics, there has been increasing emphasis on monoculture in agricultural development planning. Analysis of the economic and ecological consequences of these two cropping alternatives in a densely-populated area of eastern Nigeria suggests that a focus on monoculture as a panacea for increasing productivity and food supply is questionable. Polyculture is held to be ecologically superior to monoculture and, in the field area examined, economically more productive as well. Thus further investigation of polycultural approaches to agricultural development would appear to be warranted.
