We developed and evaluated a new approach for mapping rubber plantations and natural forests in one of Southeast Asia's biodiversity hot spots, Xishuangbanna in China. We used a one-year annual time series of Moderate Resolution Imaging Spectroradiometer (MODIS), Enhanced Vegetation Index (EVI) and shortwave infrared (SWIR) reflectance data to develop(More)
Anthropogenic interventions in natural and semi-natural ecosystems often lead to substantial changes in their functioning and may ultimately threaten ecosystem service provision. It is, therefore, necessary to monitor these changes in order to understand their impacts and to support management decisions that help ensuring sustainability. Remote sensing has(More)
Broad scale and continuous land-use/cover mapping is important for research in the context of global and climate change. We have therefore developed a method based on MODIS time-series and Random Forest classification to map forested, non-forested and plantation areas in SouthEast Asia. Our approach is optimized for regions with frequent cloud cover and(More)
Forest insect outbreaks are influenced by ecological processes operating at multiple spatial scales, including host-insect interactions within stands and across landscapes that are modified by regional-scale variations in climate. These drivers of outbreak dynamics are not well understood for the western spruce budworm, a defoliator that is native to(More)
Urban areas provide the living space for the majority of the world population. Well-being and health within urban areas is influenced by environmental and socioeconomic variables. To analyze the potential health risk in cities one has to integrate multi-dimensional and multi-scale information describing socioeconomic, environmental and health-related(More)
