    Sammanfattning : Popular Abstract in Swedish Ökad livsmedelsproduktion utgör ett viktigt steg för att uppnå livsmedelssäkerhet i Kamerun. Under det senaste halvseklet har ökningen av produktionen i huvudsak uppnåtts genom ökad uppodling. LÄS MER

  3. 12. Natural enemies: Functional aspects of local management in agricultural landscapes

    Författare :Helena Hanson; Biodiversitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
