    Author : Jonatan Jönsson; Emma Tibbling Lingwall; [2023]
    Keywords : Analys genom syntes; Göteborg; Mångfunktionalitet; Perceived Sensory Dimensions; Vattennära park;

    Abstract : Urbaniseringen i Sverige har varit kraftig de senaste 200 åren och tillväxten sker främst genom förtätning då det ses som en resurseffektiv och hållbar markanvändning. Förtätning bidrar dock till att grönområden utsätts för högre besökstryck vilket medför att dess potential att bidra med sociala, estetiska och ekologiska värden försämras. READ MORE

    Abstract : The Swedish national plan for reapproval of hydropower describes that hydropower plants (HPPs) are required to be reassessed to ensure that modern environmental conditions are set for the permits. Since dams and HPPs create barriers for migrating fish and consequently disfavor biological diversity, one consequence of the national plan is that fishways are being constructed. READ MORE
