Sribunruang Village, wherethe study of subsistence lifestyle of the Khmu was taken place, is located in Huay Sai district, Bokeo province in Laos. There are four periods of development and changes of the village. The founding period (1966-1977) was pioneered by seven Khmu families, where they had a temporary shelter at a military camp or “Pang”. The self-changing period (1978-1985) was the time the village separated itself from Meechai Sawang village led by the village head who was also the community leader. The changing period (1986-2000) was when the Party announced a guideline for change. The government opened the country and accelerated the implementation of national development plans. A road was constructed and electricity was brought into the village. Private companies came to encourage the villagers to grow corn for animal feed, and the community economy was expanding at the time. The present period (2000-2011) was when the villagers had more contacts with urban societies and there were a large number of households. The study results revealed that, prior to roads being constructed that led to the village, residential buildings were clustered on the slope and the expansion was circular. In 1996 and following the road construction however, house construction took place on both sides of the road. Economically, the villagers changed from slash-and-burn farming practices to corn cultivation and other jobs. Their lifestyles, livelihoods and society had also changed with some members working outside their community. Furthermore, collective labor practices were changed to paid labor.
