- A synthesis is provided of Late-glacial (14-9 ka BP) environmental changes in lowland Switzerland (the 'Swiss Plateau'). The chronology of deglaciation and subsequent developments in vegetation cover in the area are summarised. The sequence of climatic variations experienced in the region during the Late-glacial is then described and a curve representing the main palaeotemperature variations is presented.

- Land-use history, soil ersosion, lake trophy and lake-level fluctuations during the last 3000 years werereconstructed through a multidisciplinary palaeolimnological study (pollen, plant macrofossils, diatoms,physical and chemical analysis, magnetic measurements and radiometric methods) of a small eutrophiclake in southern Sweden (Bj~resjOsjOn, Scania). There are striking responses in diatom, chemical,sediment yield and magnetic records to land-use changes documented by pollen analysis or historicalsources, and to lake-level changes identified from sedimentary changes. Our multidisciplinary approachassists interpretation of the processes controlling long-term changes and separation of the effects ofdifferent factors (land-use changes, lake-level fluctuations) on individual biostratigraphical records.Climate has controlled processes in the lake indirectly, through lake-level fluctuations, from the LateBronze Age to the Viking Age (700 BC-AD 800). Since the Viking Age, land-use controlled most of thechanges observed in the lake's development and soil erosion processes. Major changes in lake developmentoccurred during the last 200 years, due to a drastic increase in soil erosion and water eutrophicationduring a period of agricultural modernization.

- The lake Bjaresjosjon, Southern Scania, Southern Sweden, was studied in the context of the project 'The cultural landscape of the past 6000 years in Southern Sweden'. Pollen, plant macrofossils, diatoms, physical and chemical analysis, magnetic measurements and radiometric methods (Pb-210, C-14) have been used to study palaeoecological changes, i.e. climate, land use, lake trophy and soil erosion during the past 3000 years. This multidisciplinary study shows striking responses of diatom communities, physical and chemical characteristics, sediment yields and magnetic parameters to land-use changes and lake-level fluctuations. Moreover, the latter are closely related to the settlement history at the site, inferred from archaeological records and historical sources. Before 650 AD, the limnological development was affected mainly by lake-level fluctuations, but partly also by human impact (extensive forest clearings and dominant pastoral farming). With the expansion of arable farming (around 650 AD), human impact on the landscape was the major factor influencing soil erosion processes in the catchment and limnological changes in the lake.

Tidskriftsartikel (refereegranskat)abstract
- A modem pollen/land-use data-set of 124 surface samples (moss polsters) from different vegetation and land-use types in south Sweden is presented. The samples are from non-fertilized grazed areas, burned and grazed heaths, traditionally managed fodder-producing meadows and cultivated fields, and deciduous forests. Twenty nine environmental (e.g. management type, soil chemistry) variables are available for the 124 samples. Patterns of modern local pollen variation in relation to these environmental variables are explored by canonical correspondence analysis (CCA) and tested by associated statistical procedures. The modem data-set is used to aid interpretation of extra-local pollen sequences from two small lakes and one mire in south Sweden, using CCA as a means of comparing modem and fossil spectra. The resulting land-use reconstructions are compared to earlier interpretations of the same pollen-stratigraphical data using the more traditional ''indicator-species'' approach. Emphasis is placed on the history of mowing and grazing in south Sweden as an example of the potential uses of the comparative approach for interpretating fossil pollen data in terms of past land-use.
