  1. 1. Sensory Quality and Consumer Perception of Wheat Bread : Towards Sustainable Production and Consumption. Effects of Farming System, Year, Technology, Information and Values

    Författare :Iwona Kihlberg; Einar Risvik; Lisbeth Johansson; Stefan Sahlstrøm; Uppsala universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Domestic sciences; Product quality; Production quality; Sustainability; Organic farming; Wheat; Organic Food; Bread; Milling; Breadmaking; Sensory analysis; Consumers; Information; Values; Food acceptance; Hushållsvetenskap; Domestic science and nutrition; Hushålls- och kostvetenskap;

    Sammanfattning : In order to study the effect of production systems aimed at sustainability on product quality and of sensory and non-sensory factors on product acceptance – the effect of farming system, year, milling and baking techniques on the sensory qualities of wheat bread as a model product was investigated using a descriptive test, and the effect of information and values on liking of bread using consumer tests.Whole wheat and white breads were baked with wheat grown in six lots in established conventional and organic farming systems in field trails, in two subsequent years for the white bread.

  2. 2. Biodiversity in Agricultural Landscapes: Landscape and Scale-Dependent Effects of Organic Farming

    Författare :Maj Rundlöf; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Natural science; Naturvetenskap; Ekologi; Animal ecology; plants; spatial scales; species richness; Ecology; landscape ecology; agri-environment schemes; farming practice; conservation; butterflies; bumble bees;

    Sammanfattning : Declines in the distribution and abundance of many farmland species during recent decades have been attributed to agricultural intensification. Agri-environment schemes are commonly used in Europe to reduce this loss of farmland biodiversity, but their effectiveness may depend on several external factors. LÄS MER

  3. 3. Strategic nitrogen management in stockless organic cropping systems : redistribution of residual biomass for improved energy and nitrogen balance

    Författare :Tora Råberg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bioenergy; biomass management; crop rotation; ecological intensification; green manure; life cycle assessment; nitrogen cycling; organic agriculture; soil incubation; stockless cropping systems;

    Sammanfattning : Agriculture faces the challenge of producing high yields to feed a growing world population, while simultaneously addressing environmental problems such as eutrophication, emissions of greenhouse gases, loss of biodiversity and soil degradation. Organic farming can be part of the solution, as it promotes biodiversity, uses less energy for fertiliser production and often has higher inputs of organic matter to soil than conventional farming.

    Sammanfattning : The term sustainable agriculture may be formulated, but not yet practically integrated in agriculture.This thesis investigates the organic farmers´ ideas and experiences of what they consider sustainable or not sustainable in agriculture. LÄS MER

  5. 5. Temporal effects of organic farming on biodiversity and ecosystem services

    Författare :Dennis Jonason; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES;

    Sammanfattning : Agricultural intensification has caused a dramatic decline of global biodiversity and associated ecosystem services. Organic farming has been shown to partially counteract agricultural intensification by applying environmentally friendly and resource efficient farming practices, but opportunities to improve in efficiency still remain.
