11. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements
Sammanfattning : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. LÄS MER
12. Understanding ecosystem service bundles and their social-ecological patterns in a Swedish landscape
Sammanfattning : Managing landscapes in a way that ensures sustainable development and the continued production of benefits to a diverse set of people requires an understanding how people use, modify, and depend on their local environment. This thesis uses the concept of ecosystem service bundles to articulate the social-ecological dynamics that define landscapes. LÄS MER
13. Environmental management of water systems under uncertainty
Sammanfattning : Hydrological drainage/river basins constitute highly heterogeneous systems of coupled natural and anthropogenic water and pollutant flows across political, national and international boundaries. These flows need to be appropriately understood, quantified and communicated to stakeholders, in order to appropriately guide environmental water system management. LÄS MER
14. Long-term development, modeling and management of nutrient loading to inland and coastal waters
Sammanfattning : Environmental and water system protection and restoration require accurate knowledge and quantification of waterborne pollutant transport, retention-release and transformation processes taking place in the subsurface, river, lake and sea water systems, and at the interfaces between these systems. This thesis investigates the importance of spatial model resolution for such quantification and the possible long-term nutrient load development under different human perturbations and nutrient source management scenarios in the Swedish Norrström drainage basin, based on simulations with the GIS-based dynamic nutrient transport-attenuation model POLFLOW.

15. Social-ecological dynamics of ecosystem service bundles
Sammanfattning : The environments in which we live are complex, adapting and evolving in non-linear ways. The ecosystem services produced in landscapes supply resources, support livelihoods and are foundational to human wellbeing. LÄS MER
