  2. 1. Resource management in traditional farming : A case study in the dry zone of Sri Lanka

    Author : Erika Daléus; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : The potential of the traditional small irrigation systems in Sri Lanka has to a great extent been overlooked in the efforts to satisfy increasing food requirements and to bring about social development in rural communities. The aim of this study was to arrive at an improved understanding of the resource management ofthe traditional farming system in the Dry Zone of Sri Lanka. READ MORE

  4. 2. Effects of created habitats on farmland biodiversity

    Author : Annelie Jönsson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; agricultural intensification; brown hare; common pheasant; farming intensity; granivorous passerines; grey partridge; habitat creation; landscape heterogeneity; pollinators;

    Abstract : Agricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. READ MORE

  5. 3. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis

    Author : Linnéa Ahlman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cucumber; indoor farming; abiotic stress; Fluorescence gain; ESC; biotic stress; basil; dynamics; strawberries; light spectrum; greenhouse lighting control; lettuce; powdery mildew Podosphaera aphanis; Pythium ultimum; LED; classification; lemon balm;

    Abstract : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. READ MORE

  6. 4. Natural enemies: Functional aspects of local management in agricultural landscapes

    Author : Helena Hanson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

    Abstract : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. READ MORE

  7. 5. Biodiversity and biological control : effects of agricultural intensity at the farm and landscape scale

    Author : Camilla Winqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Agricultural intensity on the local field or farm scale and on the regional landscape scale affects the organisms utilizing the arable landscape, and may affect ecosystem services and functions. This thesis examines how plants, birds, community composition of ground beetles, and biological control of cereal aphids are affected by local agricultural intensity, organic farming and the surrounding landscape in Sweden and across Europe.
