Satellite and aerial remote sensing allow us to monitor diverse phenomena on Earth surface. I use dense remote sensing time-series to evaluate and capture changes on landscape associated to the complex co-evolution of natural and social systems. Using different change detection analysis, I am interested in the monitoring of agriculture systems, forest transitions. mangroves and their connection with socio-environmental issues such as armed conflict and institutional frameworks.
