Recent studies of Cambodian sites have shown angkorian land use influence on soil and landscape evolution. We try here to promote proposals, dealing with holocene soil data from south eastern Asia, to discuss human activities and the inferred changes on Holocene soil and landscape evolution.
In south eastern Asia, increasing archeological investigations are seldom combined with geoarchaeological studies which can put human occupation on their stratigraphical and environmental frameworks. Recent advances in geoarchaeology provide new data which may help to identify and refine our understanding of human occupation environment, domestic and agricultural activities throughout the Angkor metropolitan area. Soil studies have clearly shown that angkorian occupations had induced deep changes on pedological soil functioning. Temple's construction and water flows adjusting give rise to important soil movements and new landscape forms such as dikes. Soils were often deeply disturbed and even transformed by agronomic process and anthropics rejects which induce formation of cumulic brown organic soil. Remote sensing and mapping soil description revealed the extent and association of settlements with ancient fields, confirming the territorial dimension of the urban expansion of Angkor and its potential fundamental role in its operation and even its decline. In this panel, we try to promote proposals dealing with soil analysis of natural and anthropic deposits over south eastern Asia. The aim is to discuss environmental and climatic forcing in soil evolution and processing changes of the Holocene soil induced by human activities.
