6. Education for sustainable food consumption in home and consumer studies : Lärande för hållbar matkonsumtion i hem- och konsumentkunskap
Sammanfattning : Education as a means to enable sustainable food consumption has gained increasing recognition as a vital means to decrease current burdens upon both natural resources and human health. In response, the Swedish compulsory school subject of home and consumer studies, which positions education about food as core content, has been revised to incorporate in its national syllabus a perspective of sustainable development since 2011.

7. Social-ecological performance of collaborative wildlife governance : the case of Swedish moose management
Sammanfattning : Natural resources such as wildlife are part of social-ecological systems, which are characterized by inherent complexity, uncertainty, and changes. Therefore, collaborative, decentralized, and adaptive approaches tend to be preferred in environmental governance. LÄS MER
8. Large-scale releases of native species : the mallard as a predictive model system
Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

9. 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
10. 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.
