Abstract/Summary

This study investigates land use and land cover (LULC) change in the Stung Chrey Bak catchment, Kompong Chhnang province, Cambodia, over the period 1989–2008. Using a mixed-methods approach that combines satellite remote sensing (Landsat and ASTER imagery) with field interviews and participatory mapping, the research identifies significant transformations in forest cover, rice field expansion, and land tenure dynamics. The findings reveal a decline in evergreen and secondary forests, largely due to logging, agricultural expansion, and land speculation. The Khmer Rouge era (1975–1979) played a pivotal role in shaping current land use patterns through forced deforestation and irrigation development. Post-conflict periods saw further degradation due to illegal logging and weak governance. While rice field expansion has contributed to land conversion, its impact is relatively minor compared to commercial agriculture and economic land concessions. The study highlights the limitations of relying solely on remote sensing and emphasises the value of integrating qualitative data to capture local nuances. It concludes that sustainable land and water resource management in the catchment requires improved governance, integrated planning, and recognition of local land use practices.
