1. A Design Process Based on Visualization
Sammanfattning : The global market of today is tough and the competition between companies demands new ways of developing products and services. The current challenge for the design research community is to provide designers with a wider range of methods and tools to support specific activities within the design process and to improve its overall coordination.

2. Groundwater vulnerability assessment using process-based models
Sammanfattning : The focus of this thesis is on groundwater vulnerability assessment by process-based simulation models and data acquisition for these assessments. A modelling system for intrinsic groundwater vulnerability assessment in water supply areas was developed, consisting of flow- and transport models for the unsaturated zone and the groundwater zone, coupled to a geographical informa-tion system.

3. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications
Sammanfattning : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. LÄS MER
4. Process-based modelling of N losses from terrestrial ecosystems
Sammanfattning : Nitrogen (N) loss to atmosphere and ground water can contribute to environmental destruction, by N emission as the greenhouse gas nitrous oxide (N2O) and by leaching of N to contamination and eutrophication of water. Dynamic models are important keys to increase the knowledge of ecosystems N processes. LÄS MER
5. Impacts of Regional Climate Change on Swedish Forests: An Evaluation Using Process-based Regional Ecosystem Modelling Approach
Sammanfattning : The overall aim of this thesis was to provide a representative estimate of the potential impacts of climate change and increased atmospheric CO2 concentrations on Swedish forest ecosystems and the key ecosystem services they provide. In order to achieve this task, fi rst LPJ-GUESS, a process-based regional ecosystem modelling framework, was applied to explore how possible shifts in climatic zones according to a range of regional climate scenarios may lead to changes in the tree species distribution and composition, net primary productivity (NPP) and carbon sequestration capacity of potential natural ecosystems on species level and at the regional scale.
