This document summarizes a study on the impact of agrarian transformations on customary land tenure and gender relations among indigenous communities in Northeastern Cambodia. The study found that while customary tenure originally supported women's access to land, land titling efforts and market liberalization have weakened customary systems and women's land rights. Through qualitative interviews, the study examined how changes like land sales, inheritance norms, and women's participation in governance have impacted gender relations. It concludes that external land pressures now pose the greatest risk to women, and recommends strengthening land rights, improving services, and recognizing indigenous women's roles to better support their land tenure security.
