  1. 1. Assessing Mineral Resource Scarcity in a Circular Economy Context

    Författare :Hampus André; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resource-efficiency; area of protection - natural resources; electric and electronic equipment; supply risk; scarce metals; criticality assessment; material flow analysis; life cycle assessment; circular economy; complex products;

    Sammanfattning : Due to humanity’s dependence on metal resources there are growing concerns regarding impacts related to their potential scarcity, both for current and future generations. The vision of a more circular economy suggests that extending the functional use of metals through measures aiming for resource-efficiency (RE) such as increasing technical lifetime, repairing and recycling could reduce mineral resource scarcity.

  5. 4. Effects of contrasting types of marine protected areas on seagrass- and coral communities : are community-based reserves an important complement to government-managed protected areas?

    Författare :Angelica Chirico; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Coastal ecosystems, including seagrass beds and coral reefs, are among the most ecological and economical important ecosystems on Earth. At the same time as these ecosystems support livelihoods of coastal communities they are being highly degraded worldwide. LÄS MER
