Summary
The stability of land use through analyzing the main cultivation systems in Chieng Dong commune, Yen Chau district, Son La province
Analyse showed: paddy rice cultivation systems there is the most effective and has the least impact, and the swidden farming systems has the most negative impact on environment. The swidden farming system needs to be improved with special attention paid to the protection and enhancement of soil fertility. Garden system also needs to be further promoted and oriented towards highly intensive cultivation. In order to lengthen the fallow period of swidden and recover the production capacity of sloping land, more investment should be put into improving gardening techniques along with maintaining the efficient system of traditional rice cultivation practiced by local people. More attention must be paid to measures to prevent erosion, to introduction of improved cultivation models on slopping land such as intercropping with certain suitable leguminous species. Applying new techniques to raise economic efficiency of the cultivation systems is needed.
