Abstract:
Results from our project “The Impact of Disappearing Tropical Andean Glaciers on Pastoral Agriculture” funded by NASA ROSES Land cover/Land Use Change will be presented. This research investigates the role of changing climate and deglaciation on peatland systems in the high Andes of Peru and Bolivia. Peatlands, locally termed bofedales, are key resources for pastoral communities, yet many are experiencing degradation in recent years. We apply remote sensing analysis, and hydrological and vegetation studies to understand the dynamic changes in high altitude peatland ecosystems and their impact on pastoral resources. Current challenges to the sustainability of peatland systems include hydrological shifts and landuse practices. We present a detailed study of peatland vegetation communities, linkages with hydrological systems, and the current evaluation of peatland health. Next steps of needed research on socio-economic land use practices are identified.
