6. Impact of horse-keeping on phosphorus (P) concentrations in soil and water
Sammanfattning : Agricultural sources contribute significantly to the high phosphorus (P) loads in water, causing eutrophication in many of Europe’s water bodies. Consequently, priority has been given to reducing P leakage from sources, including soils used for animal farming. LÄS MER
7. Analysing the carbon footprint of food : insights for consumer communication
Sammanfattning : In Europe, food consumption is responsible for approximately 30% of total greenhouse gas (GHG) emissions. There has been huge interest in estimating the carbon footprint (CF) of food products, i.e. the total amount of GHG emitted during the life cycle of the product, and communicating these to consumers to enable them to make informed choices.

8. Impacts of land use change on river streamflow and water quality in a semi-arid catchment : assessment of a catchment under rapid and uncontrolled urbanisation
Sammanfattning : The ongoing degradation of water quality and streamflow in rivers and streams worldwide is mainly due to human action through global land use change, particularly urbanisation. Population growth and economic development are major drivers of urbanisation, which causes environmental problems such as high water demand and solid waste and wastewater generation. LÄS MER
9. Bioaugmentation for reduction of diffuse pesticide contamination : a bioprophylactic concept
Sammanfattning : Pesticides and their residues frequently contaminate surface waters and groundwater so consequently there is a great need to identify methods and practices that reduce such contamination. This thesis examined the potential of a 'bioprophylactic' concept based on the hypothesis that diffuse contamination after application in the field can be significantly reduced if pesticides are degraded as rapidly as possible after the intended effect has been achieved.

10. Floodplain remediation in agricultural streams : improved process understanding for reduced eutrophication
Sammanfattning : Anthropogenically modified headwater streams are key pathways for high nutrient and sediment loads from agriculture, sustaining eutrophication and poor water quality in downstream aquatic ecosystems. To address this challenge, stream mitigation strategies are required that complement in-field measures, to intercept internal pollutant loading in streams. LÄS MER
