Although this migration of the Yao ethnic group was able to somewhat help revive the forest area in the Doi Luang National Park, the impact on life, family and socio-culture of this ethnic group was incalculable. After their forced relocation, families were separated and women were susceptible to being lured into prostitution and victims of human trafficking. Those who could not move elsewhere had to support their families turned to the illegal drug trade. From a short period of data collection, the preliminary findings of relocating the hilltribe to a low-lying area revealed that the impact on family was not worth the upheaval, since this forced relocation created a condition for the ethnic group to have no alternative of life but to create other social problems. A recommendation from this study was that developing highland communities should be conducted on a sustainable basis, particularly on self-reliance. Relocating the ethnic group from a forested area might not be a good answer for conserving/reviving environmental and natural resources. On the contrary, promoting a living in forest areas as conservationists and raising awareness on peaceful co-existence between humans and natural resources should be a suitable alternative in current circumstances.
