  1. 6. Turning Night into Day : Does Skyglow affect Bat Activity and Timing of Emergence?

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Torge Gerwin; [2023]
    Nyckelord :Skyglow; Bats; Light pollution; Bat activity; Bat emergence; Riparian forest; Landscape composition; Multi-scale landscape; Landscape management; Sweden;

    Sammanfattning : Artificial brightness of the night sky caused by the backscatter of artificial light in the atmosphere is a consequence of ongoing urbanization. Skyglow covers 88 % of Europe’s surface and poses significant threats to biodiversity. Extensive research on responses of bats to direct light pollution already revealed significant impacts. LÄS MER

  3. 7. Upscaling agroecology in Sweden : a participatory-backcasting approach to investigate top-down measures for promoting an agroecological transition of the Swedish agricultural system

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Pablo Ratti; [2023]
    Nyckelord :Agroecology; transition; top-down; scenario; participatory policies;

    Sammanfattning : Alongside its important contribution to the increase of yields, industrial agriculture has also generated environmental, social and economical negative side effects. Moreover, the forecasted growth of the world’s population puts more pressure for solutions on how to increase food supply while reducing the negative effects of the current agricultural system.

  4. 8. The ecological impact of artificial light at night in landscape architecture : strategies and guidelines for street lights for the benefit of biodiversity and local wildlife

    Kandidat-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Zozan Altun; [2023]
    Nyckelord :light pollution; artificial light at night; ecology; biodiversity; local wildlife; landscape architecture; guidelines; strategies;

    Sammanfattning : Artificial light at night (ALAN) is an increasingly common form of light pollution that contributes to biodiversity loss, loss of dark habitats, disrupting populations both on an individual- and population level by invading biodiversity hot spots. Recent studies show that artificial light is increasing at a rate of approximately 6% annually over Earth’s surface, and 88% of Europe and 47% of the United States experience light pollution on a nightly basis.

  5. 9. Den mörka sidan av ljuset

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Cornelia Flemming; [2023]
    Nyckelord :Safety; Street light; Light pollution; ALAN; Biodiversity; The City of Helsingborg; Municipality; Earth and Environmental Sciences;

    Sammanfattning : The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. LÄS MER

  7. 10. From Ocean to Table: Microplastic contamination in Nordic salts

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Anna Nyika; [2023]
    Nyckelord :Microplastic MP ; MP pollution; plastic pollution; sea salt; rock salt; Nordics; Iceland; Denmark; plastic waste management; human health; marine environment.; Earth and Environmental Sciences;

    Sammanfattning : Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. LÄS MER
