The potential for alley cropping as a sustainable land-use system in the volcanic islands of the South Pacific
1992
Rogers, S.
In the high volcanic islands of the South Pacific, the sustainability of food crop production by traditional shifting cultivation is being threatened by the increasing pressure for land. Increased demand for food and export crops requires that development of sustainable crop production systems for the small scale farmers is given high priority by researchers. Biophysical and socio-economic conditions in the region are described and data of alley cropping experiments in Africa and Asia are reviewed and compared with those from the Pacific Islands. Although the results of growing nitrophilic crops such as maize on sandy soils in Africa are promising, more data is required on the effects of alley cropping on crop yields and soil properties, especially on root crops such as taro on volcanic soils.
