  2. 1. Forest decline in South Central Ethiopia : Extent, history and process

    Author : Gessesse Dessie; Carl Christiansson; Johan Kleman; Peter Kinlund; Mats Widgren; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forest decline; people-forest interaction; boundaries; khat expansion; remote sensing; social survey; south central Ethiopia; Awassa watershed; Wondo Genet; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

    Abstract : This study presents the extent, history and process of forest decline in Awassa watershed, south central Ethiopia. By combining different data sources such as satellite images, social surveys and historical documents, forest decline is described quantitatively and qualitatively and the main causes behind this process are identified.

  4. 2. Ecosystem Services and Disservices in an Agriculture–Forest Mosaic : A Study of Forest and Tree Management and Landscape Transformation in Southwestern Ethiopia

    Author : Tola Gemechu Ango; Lowe Börjeson; Tobias Plieninger; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conservation; deforestation; ecosystem disservices; ecosystem services; forest; Ethiopia; land grabbing; livelihood; Oromia; policies; political ecology; trees; tropical landscape mosaic; Geography with Emphasis on Human Geography; geografi med kulturgeografisk inriktning;

    Abstract : The intertwined challenges of food insecurity, deforestation, and biodiversity loss remain perennial challenges in Ethiopia, despite increasing policy interventions. This thesis investigates smallholding farmers’ tree- and forest-based livelihoods and management practices, in the context of national development and conservation policies, and examines how these local management practices and policies transform the agriculture–forest mosaic landscapes of southwestern Ethiopia.

  5. 3. Soil Organic Matter Dynamics and Methane Fluxes at the Forest – Tundra Ecotone in Fennoscandia

    Author : Sofie Sjögersten; Gaius Shaver; Uppsala universitet; []
    Keywords : Decomposition; forest – tundra ecotone; environmental change; Fennoscandia; methane; soil organic matter; subarctic.; naturgeografi; Physical Geography;

    Abstract : This thesis presents results from several studies that have focused on the carbon and nutrient dynamics in soils at the forest – tundra ecotone in Fennoscandia. The main objectives of the study were: (i) to investigate the links between the physical environment, above-ground vegetation communities, soil carbon storage, nutrient status and the chemical composition of the soil organic matter (SOM), and (ii) to quantify trace gas fluxes (methane and carbon dioxide) between mesic soils and the atmosphere.

  6. 4. Deep Roots and Tangled Branches : Bureaucracy and Collaboration in Natural Resource Governance in South India

    Author : Marcus Wangel; Hans Blomkvist; Nils Hertting; Daniel Nohrstedt; Victor Galaz; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; collaboration; networks; governance; development administration; bureaucracy; public officials; roles; institutional analysis; informal institutions; rules-in-use; political ethnography; natural resource governance; forest governance; common pool resources; India; Kerala; Statskunskap; Political Science;

    Abstract : This is a study about collaboration within bureaucracies tasked with natural resource management in the contemporary Global South. It seeks to fill a considerable knowledge gap in the extant literature by exploring how individual public officials perceive the policy environment they work in. READ MORE

  7. 5. Plant Population Dynamics and Biotic Interactions in two Forest Herbs

    Author : Christel Gustafsson; Martin Zobel; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Sanicula europaea; Dentaria bulbifera; Cost of reproduction; grazing; competition; dispersal limitation; patch suitability; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Abstract : In Sweden today, deciduous woodlands are often restricted to small isolated remnants of what it once was. Managing practices have changed concerning both cattle grazing and logging. Thus, dispersal, habitat requirements and their importance for forest species distributions become a relevant issue. READ MORE
