  1. 16. Urban shades of green : Current patterns and future prospects of nature conservation in urban landscapes

    Författare :Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; Stockholms universitet; []
    Nyckelord :urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. LÄS MER

  3. 17. The void : Urban wasteland as political space

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban void; urban wasteland; urban planning; urban politics; space; rhythm; undecidable; montage; Derrida; Massey;

    Sammanfattning : The rugged field and group of trees between housing estates or next to the railroad tracks, the left-over space of deserted industrial areas, the vacant demolition site of a central city block – they could all be termed ‘urban voids’. However, they are often anything but voids, in a literal sense, as they are not empty, or deserted. LÄS MER

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Urban; ecosystem services; valuation; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : In an ever more urban world, the role of green spaces in cities is increasingly highlighted for their capacity to provide ecosystem services for human well-being. Yet, the value of urban green spaces is still widely overlooked in urban policy and planning. LÄS MER

  7. 20. Traffic-related pollutants in urban snow : Concentrations, size fractionation, and release with snowmelt

    Författare :Arya Vijayan; Maria Viklander; Helene Österlund; Göran Blomqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban snow; Traffic pollution; Suspended solids; Metals; PAHs; Tire and Road wear Particles T RWPs ; Microplastics MPs ; Size fractionation; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

    Sammanfattning : In urban areas with seasonal snow, traffic-related pollutants such as solid particles, metals, chloride, organic pollutants, and microplastics (MPs) can be temporarily stored in snowbanks along roads and streets. When the snow melts, it releases the accumulated pollutants and the resulting snowmelt with diverse pollutants may partly infiltrate into the ground, or enter storm sewers and eventually be discharged into, and impact on, the receiving waters.
