Satellite Imagery and Community Perceptions of Climate Change Impacts and Landscape Change
Satellite Imagery and Community Perceptions of Climate Change Impacts and Landscape Change
How does one “know” climate change is occurring? Scientists rely upon data collecting instruments, such as satellites, to monitor change in the environment at multiple scales. The Landsat satellite, for example, provides a unique perspective of changes occurring around the globe over recent decades. Local communities, such as Andean herders, have rather different methods of monitoring change that are primarily experiential based and draw upon local observations and knowledge. Looking through the lens of the satellite and drawing on the experience of the pastoralist, the trends of peatland change in Sajama National Park, Bolivia are identified and discussed. Peatlands are important for pastoral production and also provide key ecosystem services throughout the high Andes. The comparison of different knowledge sets on climate change show both complementary and divergent assessments of change. Both are valid, and considered together provide a more holistic understanding of landcover change at the local level.
