The Sentinel Landscapes (SL) initiative is comprised of geographic areas or sets of areas with a broad range of biophysical, social, economic and political conditions. A core component of the SL network is a set of Land Degradation Surveillance Framework (LDSF) sentinel sites, where intensive data collection is taking place using co-located biophysical and socio-economic surveys in order to collect information on a number of social-ecological indicators. The initial set of SL sites were established in 2012, growing into a network of 10 landscapes by the end of 2014.

We work towards the application of GeoScience in real decision contexts, such as climate change adaptation, hydrological effects of changes in climate and land cover, targeting of agroforestry interventions, provision of soil fertility and surveillance advisory services for smallholder farmers, digital soil and land use/cover mapping, and measuring impacts of interventions, all using open source software.
