摘要

The results of development activities and experiences on adaptive trials in a watershed understudy (1998—2001) are highlighted. Study area is in the Bandarban hill district. Productivity has been deteriorating due to various factors. To improve the farm productivity and to minimize soil erosion attempts have been made with participation of the poor hill farmers. Tree planting by Auger Hole Method minimized soil loss, planting time and labor costs manifolds over the traditional tree planting practices without sacrificing the survival rate of seedlings. The auger provided to tribalon-tribal communities for tree planting purpose and proved useful considering the easy handling facility, mostly for the seedlings in bag of 4″ X 6″, 5″X7″ and 6″X9″ sizes. To combat soil loss five adaptive trials are being conducted with Collaborating Farmers (CFs). Trials have increased crops productivity to some extent and intensified the land use systems but there are mixed experiences of failure and success. In these trials forest and horticultural species including agricultural crops introduced are performing well. The entirely unused seasonal ditches, natural water reservoirs inside hill series and poorly managed perennial ponds have been brought under cultivation for ploy culture of fishes. The fish production contributed to their income. Realizing potentiality of fish production, CFs have excavated perennial ponds and reorganized the backyard ditches into perennial ponds, which are contributing to harvesting scarce water and utilizing for farm activities. To diffuse the concepts, it is felt necessary to continue these works with their participation.
