    Sammanfattning : The aim of this thesis has been to reconstruct paleoenvironment, paleohydrology and paleoclimate in coastal southern Mozambique, with emphasis on tracing past flooding events on the lower Limpopo River floodplain. In order to extend flood chronologies beyond periods covered by instrumental data, sediments from lakes on the floodplain were studied (Lake Lungué, Coassane Oxbow, Lake Magandane and Lake Soane).

  2. 2. När floden märkte marken : Om bruket av översvämningsmark längs med Emån och Ätran 1500–1910

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; historical geography; agricultural history; water history; floodplain; Sweden; wetland reclamation; meadows; Emån; Ätran; agricultural transformation; human-environment relations; geografi med kulturgeografisk inriktning; Geography with Emphasis on Human Geography;

    Sammanfattning : Large landscape transformations were an integral part of the agricultural revolution in Sweden, starting during the late 18th century. The 19th century was an especially intensive century when it comes to the transformation of the cultural landscape, not the least marked by extensive changes in the use of agricultural wetlands with interventions in watercourses, lowering of lakes and wetland reclamation.

  3. 3. Climate in the eastern Mediterranean during the Holocene and beyond – A Peloponnesian perspective

    Författare :Martin Finné; Karin Holmgren; Hanna S. Sundqvist; Georgia Destouni; Neil Roberts; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stable isotopes; U-Th dating; stalagmites; climate variability; flooding history; eastern Mediterranean; southern Greece; Holocene; Pleistocene; Physical Geography; naturgeografi;

    Sammanfattning : This thesis contributes increased knowledge about climate variability during the late Quaternary in the eastern Mediterranean. Results from a paleoclimate review reveal that regional wetter conditions from 6000 to 5400 years BP were replaced by a less wet period from 5400 to 4600 years BP and to fully arid conditions around 4600 years BP.
