摘要

Combining trees, crops and vegetables is not a new concept in Bangladesh. It has been embedded in traditional forest plantation activities since the adoption of taungya. Taungya was first introduced in Myanmar where farmers were given parcels of degraded forest reserves to produce food crops and to help establish and maintain timber trees. This system was later adopted in Bangladesh at Kaptai in the early 1870's (Alim, 1993). It includes the planting of shrubs, vegetables and other secondary crops i.e., ginger, turmeric, eggplant, lemon, papaya and banana along with different tree species. In the northern regions of Bangladesh, agroforestry serves as an insurance against crop failure and adds extra economic benefits. Zhoom cultivation is a traditional practice in the Chittagong Hill Tracts. Growing betel vines on trees and the cultivation of pineapple under jackfruit orchards is practiced in tribal areas in Madhupur, Maulvibazar and other regions of the country. But, in spite of its real potential, agroforestry remains at a low level overall.
