Site Description
Houay Pano is a small agricultural catchment (60 ha) of northern Laos, 10 km from the UNESCO world heritage city of Luang Phrabang, in a sloping land environment with annual detailed land use maps since 1998: impact of land use changes (from annual crops –upland rice, Job’s tear and maize - cultivated with slash and burn system to perennial – teaks) and climate changes upon hydrologic and sedimentary budgets, fluxes and qualities (including bacterial). The mean slope is 48%. Alfisol, Ultisol, Entisol developed on shale and shist. Equipments include an automatic meterological station since 2001, 4 weirs to monitor discharge from nested catchments, suspended and bedload since 2001, automatic suspended load samplers. 12 piezometers since 2011 and measurements every two weeks since 2006 of soil electric resistivity (geogphysical tomography). More information available on http://www.msec3.net/portal/, and in Valentin et al. (2008), AGEE; Ribolzi et al. (2011),Envir. Management; Huon et al (2013), AGEE. The Dong Cao catchment belongs to the MultiScale Environmental Changes Network (MSEC) which is a long term monitoring network of experimental catchments in South-East Asia (Laos, Thailand, Vietnam) and to the French SOERE-RBV Network. It serves as experimental site for three projects funded by the French Agency for Research (ANR).

Purpose
The objectives of this MSEC site are fivefold: (i) monitor the impact of land use change and possible climate change upon the hydrologic and sedimentary responses at various scales from micro-plots (1 m²) under natural or simulated rainfall to micro-catchments (0.6 ha) and larger catchments (up to 60 ha); 'ii) conduct experiments on new agricultural practices and their impacts on hydrology, carbon, nutrients, pollution and erosion; (iii) provide sound data to the scientific community and to decision makers to improve land management of steep slope environment in South-East Asia; (iv) develop and test generic hydrologic and erosion models; (v) to train young scientists and students from a very wide array of disciplines.
