  2. 1. 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.

    Abstract : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. READ MORE

  5. 3. Tempo-spatial patterns of foraging by birds in mosaic agricultural landscapes

    Author : Adriaan De Jong; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Many farmland breeding bird populations decline, while large herbivorous bird species, which forage on farmland outside the breeding period, increase their numbers. Intensification of agriculture causes both processes. READ MORE
