1. Social-ecological approaches for assessment of healthy diets from sustainable food systems
Sammanfattning : .... LÄS MER
2. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs
Sammanfattning : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. LÄS MER
3. Harvesting from land and sea : Social relationships, trade networks, and spatial connectivity in changing social-ecological systems
Sammanfattning : In the era of global change, the connectivity of aquatic and terrestrial food production systems across spatial scales is increasing. At the same time, diverse actors that participate in food systems, from production to consumption, face the need to adapt their daily activities to an increasingly changing context. LÄS MER
4. Global trade, food production and ecosystem support : Making the interactions visible
Sammanfattning : Modern food production is a complex, globalized system in which what we eat and how it is produced are increasingly disconnected. This thesis examines some of the ways in which global trade has changed the mix of inputs to food and feed, and how this affects food security and our perceptions of sustainability. LÄS MER
5. Food or fuel? : trade-offs between food and biofuels globally and in small-scale organic agriculture
Sammanfattning : There are great expectations on agriculture to provide both food and fuels in the future. Previous attempts to estimate the global bioenergy potential have produced varying results, indicating major uncertainty. This thesis investigated the global theoretical 'potential', or limit, for biofuels based on current agricultural systems. LÄS MER
