31. Dispersal and environmental impact of contaminants in organic rich, fibrous sediments of industrial origin in the Baltic Sea
Sammanfattning : The health of the Baltic Sea is negatively affected by hazardous substances such as metals and persistent organic pollutants (POPs), which include legacy pollutants that were banned decades ago, but still circulate in the ecosystem. Elevated levels of legacy pollutants, identified by HELCOM as key hazardous substances, have been found in accumulations of fibrous sediments, so-called fiberbanks and fiber-rich sediments, which derive from old pulp mills along the Swedish north coast.

32. Casting for Knowledge and Landing Understanding : Exploring the management of Swedish recreational fisheries as social-ecological systems
Sammanfattning : The successful management of recreational fisheries must balance ecological, and social goals; select from and implement a range of management tools; operate under often complex governance structures; and contend with diverse human stakeholders’ expectations, desires, and actual behaviour in response to management activities. This complexity also means that there are many knowledge and research gaps regarding the information needed to meet the requirements of specific fisheries. LÄS MER
33. Global energy transitions : Renewable energy technology and non-renewable resources
Sammanfattning : The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. LÄS MER
34. Natural resources and sustainable energy : Growth rates and resource flows for low-carbon systems
Sammanfattning : Large-scale deployment of low-carbon energy technologies is important for counteracting anthropogenic climate change and achieving universal energy access. This thesis explores potential growth rates of technologies necessary to reach a more sustainable global energy system, the material and energy flows required to commission these technologies, and potential future availability of the required resources.

35. World oil supply and unconventional resources : Bottom-up perspectives on tight oil production
Sammanfattning : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.
