In 2022, the Cambodian government asked approximately 10,000 households living in the area surrounding the Angkor monuments to relocate outside of Angkor Archaeological Park to protect the Ankor ruins. The policy aimed at protecting the Angkor ruins has revealed issues such as how to deal with the problem of illegal settlements, post-relocation support policies, and infrastructure development. However, there are many unsolved questions regarding the housing type and changes in the living environment after relocation, focusing on people's lives. In this study, based on the results of a hearing survey, I compare the housing type and living environment before and after relocation, and clarify the current situation and challenges in Runta Ek Developing Area in Runta Ek Techo Sen City, how the resettlement area is affected by changes in life due to relocation.
