6. Landslides in the central Kenyan highlands : Risks and actors
Sammanfattning : Measures taken to prevent and mitigate landslides are often based on geotechnical solutions. However, to understand local effects of landslides, people’s perception, knowledge and experiences are important, as this influence the level of vulnerability, and the efficacy of adaptive and mitigating measures.

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

8. Past environmental and climate changes in northern Tanzania : Vegetation and lake level variability in Empakaai Crater
Sammanfattning : This thesis presents palaeoenvironmental data from equatorial Africa covering two important time intervals; i) the warming period forming the Pleistocene/Holocene transition and ii) the last millennium. The Empakaai Crater, in northern Tanzania contains a lake from where sediment cores, spanning two time-slices 14.8-9. LÄS MER
9. Landslide scars in the Kenyan highlands : Physical and chemical topsoil changes and landslide susceptibility assessment under tropical conditions
Sammanfattning : Farmers living in the Kenyan highlands are exposed to the risk of being affected by landslides and they are vulnerable because of lack of resources. Vulnerability can be reduced by increasing knowledge and awareness of the risk. This thesis aims to increase knowledge of landslide-related problems. LÄS MER
10. Diatoms in Lake Duluti : Tracking Environmental Variability in Northern Tanzania during the Past 1000 Years
Sammanfattning : The tropics are the regions which are least understood climatically and new data on past climate variability is necessary for reliable future modeling of climate change. This thesis contributes with new paleoenvironmental information from a small crater lake in northern Tanzania and provides an additional link between the integrated history of climate, environment and socioeconomic variability in tropical Africa.
