Since 2008, a series of collaborative projects with local communities and administrations

A dataset  (dataverse IRD) holds the results of different Random Forest classifications using the combination of Sentinel-2 Optical and Sentinel-1 Radar images. The different images were acquired in 2019. The dataset covers Saen Thong sub-district, Nan province in northern Thailand, a mountainous area with a monsoon climate. The classifications cover three categories of land: 1. uncultivated steep mountain slopes with forest (Park, protected), 2. cultivated mostly steep slopes with annual crops (e.g. upland rice, maize), or tree plantations (e.g rubber, teak, bamboo), or community forest, 3. cultivated flatland with paddy fields, besides most urbanization and modern infrastructure is also located.

A dataset contains three runoff and erosion vector maps classified by value ranges: i) a map of runoff coefficient (Krc %) predicted from local surface conditions and runoff data from 535 1- m² plots in Southeast Asia; (ii) a map of mean soil loss (kgm-2) predicted from the same database; and (iii) a map of gully index, which is based on catchment area, runoff coefficient and LS, a topographic factor. These runoff and erosion maps were produced as part of the ANR FutureHealthSEA project: predictive scenarios of health in Southeast Asia, linking land use and climate change to infectious diseases.
