  2. 21. 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.

  4. 22. Environmental Effects of Agricultural Expansion in the Upper Amazon : A study of river basin geochemistry and hydrochemistry, and farmers' perceptions

    Author : Lina Lindell; Mats Åström; Marianne Henningsson; Pasi Peltola; Tommy Claesson; Michael E McClain; Linnéuniversitetet; []
    Keywords : tropical humid forest; deforestation; land-use change; slash-and-burn agriculture; spatial variation; vertical distribution; multielement analysis; sustainable development; rural livelihoods; bosque húmedo tropical; deforestación; cambios de uso de la tierra; agricultura de tala y quema; variabilidad espacial; distribución vertical; análisis multielemental; desarrollo sostenible; cambio climático; sustentos rurales; Miljövetenskap; Environmental Science;

    Abstract : In this thesis natural science is combined with environmental psychology in order to determine how deforestation and subsequent agricultural expansion in the Peruvian highland jungle has affected the natural environment and rural livelihoods. This region is part of one of the most biodiverse areas on Earth and is also exposed to high pressure from deforestation that threatens the ecosystems as well as the well-being of local populations.

  5. 23. Coastal livelihoods : A study of population and land-use in Noarootsi, Estonia 1690 to 1940

    Author : Hele Kiimann; Tom Mels; Peeter Maandi; Göran Hoppe; Ulf Jansson; Uppsala universitet; []
    Keywords : Noarootsi; Estonia; cartographical analysis; interdisciplinary study; soil cover change; landscape history; coastal peasants; Estonian-Swedish; feudal manor system; land reform.;

    Abstract : This thesis investigates how the inhabitants formed the coastal landscape of northwest Estonia through both internal change and external impact by estate owners, provincial government and imperial decrees. Two villages on the largely Swedish populated Noarootsi peninsula, Einbi (Enby) and Kudani (Gutanäs), are examined in detail. READ MORE

  6. 24. Pollen productivity estimates and pollen-based reconstructions of Holocene vegetation cover in Northern and temperate China for climate modelling

    Author : Furong Li; Marie-José Gaillard; Mary E. Edwards; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; climate; pollen-vegetation relationships; relative pollen productivity; REVEALS model; anthropogenic land-cover change; Holocene; China; Paleoecology; Paleoekologi;

    Abstract : Model projections of future climate change require that coupled climate-vegetation models are developed and validated, i.e. these models should be able to reproduce past climate and vegetation change. Records of pollen deposited in lake bottoms and peat bogs can provide the information needed to validate these models. READ MORE

  7. 25. Dissolved organic carbon in tropical watersheds : Linking field observation and eco-hydrological modelling

    Author : Fabien Rizinjirabake; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dissolved organic carbon DOC ; Rwanda; Land use land cover variability; Climate variability and change; Rukarara River Watershed; eco-hydrological modelling; field observation;

    Abstract : Dissolved organic carbon (DOC) is a general description of the organic material dissolved in water. DOC is an important source of energy, carbon, and nutrient transfers from terrestrial to aquatic ecosystems. The export of DOC into aquatic ecosystems may contribute to the carbon balance of terrestrial ecosystems and to water degradation. READ MORE
