My main area of research is 'Geohazards, Land Degradation and Earth Observation'. My group focuses on applied use of earth observation and spatio-dynamic modelling of hazardous and land degradation processes and ecosystem performance. Geohazards and land degradation refers to processes that are a threat to our society and/or reduce the capacity of an ecosystem to deliver goods and services. Such processes include soil erosion, wind erosion, physical degradation (loss of structure, crusting), flooding, mass movements, salinization, impoverishment of the (natural) vegetation and/or reduced productivity of ecosystems in terms of biomass.
