  1. 1. Sumatranoshörningen (Dicerorhinus sumatrensis) på gränsen till utrotning - En riskanalys

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Amanda Gagné; [2021]
    Nyckelord :Sumatran rhinoceros; risk assessment; threats; conservation; Indonesia; Earth and Environmental Sciences;

    Sammanfattning : The critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. LÄS MER

  2. 2. Matlandskap : om kommuners fysiska planering för hållbara livsmedelssystem

    Master-uppsats, SLU/Department of Landscape Architecture, Planning and Management (from 130101)

    Författare :Karolina Wingård; [2021]
    Nyckelord :livsmedelssystem; jordbruk; matproduktion; foodscape; biologisk mångfald; biotoper; ekosystem; ekosystemtjänster; miljömål; Tanum;

    Sammanfattning : Food production and land use could be blamed for a lot of the global environmental issues present in todays society. With an ever increasing global population and steadily increasing effects of climate change, which threaten our crops, there is likely potential for issues to increase in scope and severity. LÄS MER

  3. 3. Dynamics of net primary production and food availability in the aftermath of the 2004 and 2007 desert locust outbreaks in Niger and Yemen

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Emma Bylund; [2021]
    Nyckelord :geography; GIS; desert locust outbreak; NPP; food availability; livelihood zones; Earth and Environmental Sciences;

    Sammanfattning : The knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. LÄS MER

    Sammanfattning : Dynestadsjön in Gamleby, Västervik municipality, has a history of collapses due to lack ofoxygen and high levels of salt, nitrogen and phosphorus. The high levels of nutrients havegiven rise to deteriorating living conditions for aquatic organisms. LÄS MER

  5. 5. Hur påverkas markorganismerna av jordbruksmetoden strukturkalkning?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Maria Gustavsson; [2021]
    Nyckelord :structural liming; agriculture; microorganisms; clay soil; respiration; earthworm population; Earth and Environmental Sciences;

    Sammanfattning : This field study was done to get an understanding of how the agricultural method called “structural liming” might affect soil organisms in a negative way. Soil organisms are crucial as they perform biological processes that improve good soil structure. This is important as it enables sustainable food production, today, and in the future. LÄS MER
