Description

• This study analyses a taungya system in a north Kilimanjaro plantation forest in Tanzania. This study does not assess the costs and revenues resulting from this system and the impacts to agriculture.
• The field research was conducted to assess survival and food crop yield and financial analysis.
• The results show that survival of 2-5 year old Cupressus lusitanica was significantly high in compartments under the taungya system compared to pure wood systems. This is because trees under taungya benefit from continuous weeding. However, lower survival was observed in later years due to damage of trees by peasant farmers in their bid to reduce root competition between trees and food crops.
• In addition, crop yields were similar in year 0 and 1 but declined thereafter due to loss of soil fertility from continued use of plot and canopy closure which shades crop trees.
• The authors suggest the taungya system as a suitable system from which both forest service and peasant farmers reap substantial benefits.
