The use of quantitative landscape reconstructions from pollen data for linking land use change and aquatic environments

Aktivitet: Föredrag eller presentationPresentation

Beskrivning

Methods for quantitative reconstructions of past land cover changes from pollen data have improved significantly over the last decades, and with the increased number of studies and estimates of the relative pollen productivity of different plants, have also become much more widely applied. The different submodels within the Landscape Reconstruction Algorithm (Sugita, 2007) allows us to reconstruct vegetation changes at different spatial scales, depending on the
selection of study sites. This can provide quantitative information on past human land use at different spatial and temporal scales. By analysis of the relationships between land use Changes and geochemical, geophysical and biological proxies of past conditions in the aquatic environment in lakes and even coastal waters, we can improve our understanding of the interactions between humans, the terrestrial and the aquatic environment at timescales that far exceed those of observational data. This in term can perhaps give us an increased understanding
of the long term processes involved, although many challenges remain, not least disentangling the role of land use and climatic changes. We will present examples of such analyses in Southern Scandinavia range from small, very local to large regional catchments in terms of spatial scales, and from centuries to millennia in terms of temporal scale.
