Graciela is a Quaternary scientist with a special interest on long-term ecology. She has been mainly working on African drylands and sensitive areas to global change; namely the Namib Desert, the Cape region, the Lower Omo region (Ethiopia) and Southern Iberia. The core of her research is focused on vegetation response to environmental change, including natural and anthropogenic activities (fire and agriculture). Graciela uses a variety of sediments ranging from biogenic accumulations (hyrax middens), paleo-lake, lacustrine and peat deposits as well as different proxies, primarily pollen and charcoal and other tools as GIS and remote sensing.



She is currently exploring four key research topics:


  • Vegetation response to past abrupt climate change in North-East Iberia (DINAMO project

  • Quaternary fire dynamics in the western Mediterranean (DINAMO and IBERVELD projects) Long-term human-environmental dynamics (Lower Omo project)

  • Present vegetation-pollen calibration for spatial reconstruction of past landscapes (HYAENA and CALIB projects)
