  4. 2. Late Quaternary climate and environmental change in the summer rainfall region of South Africa : A study using trees and wetland peat cores as natural archives

    Author : Elin Norström; Karin Holmgren; Michael Meadows; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; paleoclimate; Late Quaternary; pollen; stable isotopes; diatoms; phytoliths; dendroclimatology; South Africa; Physical geography; Naturgeografi; Physical Geography; naturgeografi;

    Abstract : This thesis contributes with information on past climate and environmental changes in South Africa’s summer rainfall region. The study is based on multi-proxy analyses on wetland peat cores and analyses of stable isotope composition (δ13C, δ18O) and wood anatomy in cross sections from subtropical trees (Breonadia salicina).

  5. 3. Holocene environmental changes and climate variability in the Eastern Mediterranean : Multiproxy sediment records from the Peloponnese peninsula, SW Greece

    Author : Christos Katrantsiotis; Stefan Wastegård; Rienk Smittenberg; Jan Risberg; Elin Norström; Sherilyn Fritz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mediterranean; Greece; Peloponnese; Holocene; sediments; diatoms; n-alkanes; stable isotopes; tectonics; climate variability; monsoons; NAO; NCP; Physical Geography; naturgeografi;

    Abstract : This thesis presents multiproxy reconstructions of the mid to late Holocene climate and environmental changes in the Peloponnese peninsula, SW Greece. The combined dataset consists of diatom, biomarker and X-ray fluorescence spectrometry (XRF) elemental data in radiocarbon-dated sediment cores taken from the Agios Floros fen and the Gialova Lagoon in SW Peloponnese and the Ancient Lake Lerna in NE Peloponnese.

  6. 4. How on Earth : Operationalizing the ecosystem service concept for local sustainability

    Author : Katja Malmborg; Lisen Schultz; Albert Norström; Elin Enfors-Kautsky; Erik Gomez-Baggethun; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ecosystem service bundles; System dynamics; Participatory methods; Usable knowledge; Leverage points; Learning; Complexity; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Ecosystem services are co-produced in social-ecological systems. Due to their social-ecological framing, ecosystem services hold the potential to be a concept around which different stakeholders with vested interests in different aspects of landscape management can meet. READ MORE

  7. 5. Environmental history in southern Mozambique : Reconstruction of flooding events, hydroclimate and sea-level dynamics since mid-Holocene

    Author : Sandra Raúl Sitoe; Jan Risberg; Elin Norström; Lars-Ove Westerberg; John Compton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Southern Africa; Limpopo River floodplain; flooding event; sea-level change; climate change; diatoms; phytoliths; mineral magnetics; grain-size; radiocarbon dating; kvartärgeologi; Quaternary Geology;

    Abstract : 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).
