  1. 1. Greenhouse gas emissions and carbon burial in a small pond

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Carlson; [2023]
    Keywords : Pond; greenhouse gas; carbon dioxide; methane; nitrous oxide; flux; ebullition; carbon burial; Damm; växthusgas; koldioxid; metan; lustgas; flöde; ebullition; kolbindning;

    Abstract : There are a lot of uncertainties when it comes to global greenhouse gas (GHG) emissions which affects society’s ability to effectively respond to climate change. Small ponds have been found to potentially play a large role in global warming. READ MORE

  3. 2. The potential nitrous oxide emissions in a permanent grassland chronosequence

    University essay from SLU/Dept. of Forest Mycology and Plant Pathology

    Author : Sandra Lillsjö Kronblad; [2023]
    Keywords : nitrous oxide emission; permanent grasslands; denitrification; nitrous; reen house gas; agriculture;

    Abstract : As a part of a larger project (Belowground biodiversity of grasslands – conservation needs and potential to promote sustainable agriculture), this study aims to investigate potential nitrous oxide (N2O) emissions and microbial gene abundances needed for the production (nirS and nirK) and reduction (nosZI and nosZII) of nitrous oxide in soil of permanent grasslands of various age. Thegrasslands have at different times been converted to permanent grasslands and are of interest because of the possibility to shed more light about the passage of time’s affects on the soil microbialcommunities and their activity.

  4. 3. Assessing the Eco-efficiency of Swedish Crop Farms and the Role of Subsidies : a Directional Distance Function Approach

    University essay from SLU/Dept. of Economics

    Author : Therese Ratilla; [2023]
    Keywords : Swedish crop farmers; CAP subsidies; FADN; stochastic frontier analysis; multi-output; one-step approach;

    Abstract : The agriculture sector’s contribution to global greenhouse gas (GHG) emissions and its increasing vulnerability to the effects of climate change warrants assessments considering not only on-farm productivity but also the industry’s environmental sustainability. Utilizing the concept of eco-efficiency, this study analyzes the environmental performance of Swedish crop farms by incorporating farm-level GHG emissions as an undesirable output in the production function.

  5. 4. Underlying mechanisms behind nitrous oxide emissions in oilseed radish, Raphanus sativus var. oleiformis, and Phacelia tanacetifolia

    University essay from SLU/Dept. of Plant Breeding (from 130101)

    Author : Annika Swensson Källén; [2023]
    Keywords : nitrous oxide; glucosinolates; greenhouse gases; oilseed radish; Phacelia tanacetifolia; cover crops; labile C;

    Abstract : Greenhouse gases are a driving force of climate change and the annual greenhouse gas emissions were higher between 2010-2019 than any other time in human history (Skea et. al. 2022). READ MORE

  6. 5. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE
