Global population growth and increasing wealth exert pressure to convert forests to agricultural, industrial or residential land. Land use changes, together with the diversity in physical and socio-economic conditions in the uplands of northern Vietnam and Laos, require new sustainable land use options for obtaining food security as well as for environmental protection. A Knowledge-Based System KBS approach, whereby local and scientific knowledge are combined to develop new land use options, is being tested by a consortium of researchers, extension agents and farmers in the Dong Cao catchment, Hoa Binh province, Vietnam, and in Pakchae village, Park ou District, Luangprabang, Laos.

The underlying cause of this land degradation has been the farming habits of migrants of varying ethnic groups who have settled in the area since The indigenous farming knowledge of these people and the role of that knowledge in soil erosion were examined by a series of household surveys. They enabled farming practices to be related to ground cover established from a Landsat 7 ETM Enhanced Thematic Mapper , and erosion data from a series of erosion bridge measurements.
This could then be combined with the understanding of farming practices to reveal the relative roles of farmer behaviour, crop cover, and slope and soil characteristics in the erosion process. Land use, local people's knowledge and economic realities are the main factors, as well as natural conditions, that drive this land degradation. Patrick S. Arpan Kundu. Samsul Atra. James Kain.
