  1. 1. TRACKING WASTEWATER EMISSIONS IN RIVERS ENTERING GULF OF BOTHNIA COAST

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Helen Mkandawire; [2023]
    Nyckelord :Nutrients inputs; wastewater; coastal waters; Gulf of Bothnia; wastewater emissions; nutrient transportation; marine water; nutrient loading; eutrophication.;

    Sammanfattning : The Gulf of Bothnia consists of two sub-basins in the northern Baltic Sea: the Bothnian Sea (salinity 4-5‰) and Bothnian Bay (salinity 2-3‰). Changing nutrient concentrations and signs of eutrophication has recently been observed in the Gulf of Bothnia. LÄS MER

  3. 2. Reindeer decrease soil carbon stocks and deplete labile soil carbon

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Josua Seitz; [2022]
    Nyckelord :Reindeer; SOC; soils; Finnland; 13C NMR;

    Sammanfattning : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

  4. 3. Closing the loop of human waste: can eco-innovation be the key? Findings from the case study of the LooPi urinal

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Maricruz Vargas Esquivel; [2022]
    Nyckelord :eco-innovation; eco-toilet; wastewater reuse; circular economy; Vienna; Earth and Environmental Sciences;

    Sammanfattning : The Circular Economy (CE) primary goal is to be capable of "closing the loops" in processes by changing the idea of resources and waste. Eco-innovation ("the introduction of any new or significantly improved product (good or service), process, organizational change or marketing solution that reduces the use of natural resources (including materials, energy, water, and land)" could be a way to encourage industries to develop more solutions with "closed-loop" systems.

  5. 4. Effekter av kalkkväve i odling av isbergssallat : ett mindre fältförsök

    M1-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Oskar Olsson; [2022]
    Nyckelord :Isbergssallat; kalkkväve; gödsling; Iceberg lettuce; calcium cyanamide; fertilization;

    Sammanfattning : Odling av isbergssallat kräver stora insatser per odlat hektar och innebär många risker för odlaren. Isbergssallaten har en relativt kort kulturtid på 6–10 veckor från plantering till skörd. Den ställer höga krav på näringstillförsel, vatten och temperatur under hela plantans tillväxt för att nå ett gott resultat i sin odling. LÄS MER

  7. 5. Biowastes for Plant Production : a guide to plant biostimulants

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Toolie-Mina Anderback; [2021]
    Nyckelord :biological waste; by-products; organic inputs; fish protein hydrolysate; vermicompost; seaweed extract; fish waste; macro algae;

    Sammanfattning : Biostimulants are a suggested tool to achieve sustainable plant production. These are products sourced from biological processes or extracted from biological material, which induces physiological responses in plants. LÄS MER
