6. Transformations towards Sustainable Food Systems : Pathways, Governance, and Actors in a Swedish and European Union Context
Sammanfattning : Food systems are central to global sustainability, while being complex systems where places and people are intertwined over large distances and at different scales. Transformations towards sustainable food systems have been called for in both research and policy, and Sweden and the European Union have declared high ambitions to act as global leaders in these transformations.

7. Epiphytic lichen responses to nitrogen deposition
Sammanfattning : Nitrogen (N) deposition has increased globally over the last 150 years and further increase is predicted for the future. Nitrogen is an important nutrient for lichens, involved in many processes in both photobiont and mycobiont. However, N can be a stressor, causing many lichens and lichen communities to disappear with increased deposition. LÄS MER

9. Particulate phosphorus accumulation and net retention in constructed wetlands receiving agricultural runoff : Critical analysis of factors affecting retention estimates
Sammanfattning : Övergödning är ett allvarligt miljöproblem, som bland annat orsakar omfattande blomningar av alger och blågrönbakterier. I söt- och brackvatten är fosfor ofta det mest begränsande näringsämnet för dessa organismer, varför en minskning av fosfortillförseln är nödvändig för att nå förbättringar. LÄS MER
10. Rätt och kretslopp : Studier om förutsättningar för rättslig kontroll av naturresursflöden, tillämpade på fosfor
Sammanfattning : The point of departure is the assumption that ecological sustainable development is the highest goal for society. While the over-riding purpose of the study is to demonstrate how this objective can be of relevance to law, the means is to adapt the judicial system to achieve ecocycles of natural resources that are as self-contained as possible, against a background of the often dissipative flows of thepresent day.
