Houay Pano is a small agricultural catchment (60 ha) of northern Lao PDR, 10 km from the UNESCO world heritage city of Luang Phrabang, in a sloping land environment monitored since 1998. The objective is to monitor the impact of land use changes from annual crops (upland rice, Job’s tear and maize, cultivated with slash and burn system) to perennial (teak trees), and of climate changes upon hydrological and sedimentary fluxes and budgets, along with water quality (including microbial contamination). The mean slope is 48%. Alfisol, Ultisol, Entisol developed on shale and shist. Monitoring devices include an automatic meteorological station, weirs to monitor discharge from nested catchments, suspended sediment, and bedload, piezometers, and electrical resistivity.
