  • How mankind has shaped European nature

    • A monographic book volume on the history of the rural landscape of Europe is presented (Emanuelsson, The rural landscape of Europe. How man has shaped European nature, 383, 2009). The focus is on various land-use phases, their history from the Neolithic period to modern time and the survival of traditional farming today in Europe. This is described and illustrated by examples from marginal farming areas, particularly in mountainous regions of southern and northern Europe. Some of these are important as modern analogues when interpreting past cultural landscapes.

  • Long-term changes in floristic diversity in southern Sweden: palynological richness, vegetation dynamics and land-use
  • 2008
  • Ingår i: Vegetation History and Archaeobotany. - : Springer Science and Business Media LLC. - 0939-6314 .- 1617-6278. ; 17:5, s. 573-583
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract in UndeterminedThe rarefaction technique is applied to two Holocene pollen sequences (covering the last 12,000 calendar years) from two lakes in southern Sweden. One represents an open agricultural landscape, the other a partly wooded and less cultivated landscape. The inferred palynological richness is interpreted as an approximate measure of floristic diversity at the landscape scale. The overall trend is an increased diversity from the mid-Holocene to the Modern period, which is linked to a parallel rise in human impact. The pattern is similar for the two sites with peaks corresponding to archaeological periods characterised by deforestation and expanding settlement and agriculture. The highest diversity was reached during the Medieval period, about A.D. 1,000-1,400. Declining diversity during the last 200 years characterises the agrarian landscape. These results confirm, for southern Scandinavia, the "intermediate disturbance" hypothesis for biodiversity at the landscape scale and on millennial to century time scales. They have implications for landscape management in modern nature conservation that has the purpose of maintaining and promoting biodiversity.

  • One hundred years of Quaternary pollen analysis 1916–2016
  • 2018
  • Ingår i: Vegetation History and Archaeobotany. - : Springer Science and Business Media LLC. - 0939-6314 .- 1617-6278. ; 27:2, s. 271-309
  • Tidskriftsartikel (refereegranskat)abstract
    • We review the history of Quaternary pollen analysis from 1916 to the present-day, with particular emphasis on methodological and conceptual developments and on the early pioneers of the subject. The history is divided into three phases—the pioneer phase 1916–1950, the building phase 1951–1973, and the mature phase 1974–present-day. We also explore relevant studies prior to Lennart von Post’s seminal lecture in 1916 in Kristiania (Oslo) in an attempt to trace how the idea of Quaternary pollen analysis with quantitative pollen counting and stratigraphical pollen diagrams developed.

  • Temporal cultural landscape dynamics in a marginal upland area: agricultural expansions and contractions inferred from palynological evidence at Yttra Berg, southern Sweden
  • 2010
  • Ingår i: Vegetation History and Archaeobotany. - : Springer Science and Business Media LLC. - 0939-6314 .- 1617-6278. ; 19:2, s. 121-136
  • Tidskriftsartikel (refereegranskat)abstract
    • Agrarian history and local cultural landscape dynamics have been documented through pollen analysis of a peat core within the hamlet of Yttra Berg, which is situated in an upland area of southwest Sweden. The sequence covers the last 5,000 years, from Neolithic to modern time. Wood pasturing started at 2000 b.c., followed by grazing and small-scale cultivation with 500 year cycles from 650 b.c., and permanent fields of agriculture from a.d. 1150. The area was abandoned during the period a.d. 1350-1550. Three cycles of succession related to land-use have been identified for the period 650 b.c. to a.d. 1550. Correlation with frequent clearance cairns in the area is discussed. Recessions of agriculture/settlement during the late Middle Ages and late modern time are documented. Pollen data indicate increased landscape and plant diversity since the Neolithic, closely linked to openness of the agrarian landscape. These results are important for landscape restoration.
