Research objectives: Can analyze the current situation and characteristics of natural rehabilitation of flora carpet on lands after shifting cultivation as a basis for building the classification of rehabilitation capacity in the study area; can assess the protection capacity of flora carpet on lands after shifting cultivation, can classify rehabilitation potential of forest on lands after shifting cultivation through forest time natural rehabilitation, and propose some silviculture solutions for forest rehabilitation on lands after shifting cultivation in the watershed protection area.
This study explains the dynamics of shifting cultivation and agro-forestry practices among farmers of the Tay et hnic group (one of the largest in the region)in Tat hamlet and recommends measures to replace shiftin cultivation by agro-forestry as the livelihood base. The analysis is mainly quantitative.
Agroforestry practices have existed in Vietnam and in many countries throughout the world for a long time. Among others, these sys tems include traditional shifting cultivation typical of ethnic minority groups and home gardens seen in many rural landscape ecologies
2 Cropping systems for fruit
Fruit is produced in almost every farming system. Some fruits are collected in the natural vegetation (‘in the wild’). In shifting cultivation systems, fruit trees are often planted along with the field crops after a plot has been cleared. During the first year or two of the next fallow period the resurging natural vegetation is slashed to enable the fruit trees to survive and bear fruit.

Rotation and fallow
Many tropical farming systems have originated from shifting cultivation; a system of food production based on a rotation of cultivation followed by a long fallow period. The fallow period ensures a natural recovery of soil fertility.
