  1. 1. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Magnusson Petter; [2023]
    Keywords : Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Abstract : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. READ MORE

  3. 2. More Fish, more Mahasoa? A Quantitative Analysis of Food Security & Poverty Reduction in Rural Small-scale Aquaculture in Madagascar

    University essay from Lunds universitet/Ekonomisk-historiska institutionen

    Author : Gianna Laura Angermayr; [2023]
    Keywords : Madagascar; Small-scale Aquaculture; Pond Aquaculture; Integrated Rice-Fish Farming; Community Well- being; Poverty Reduction; Food Security.; Business and Economics;

    Abstract : The role of food-producing sectors such as agriculture and aquaculture in the development process is debated and while some consider industrial production to be the answer, others suggest that small-scale production can also make contributions to poverty reduction and food security. This thesis aims to shed light on these relationships by performing quantitative analyses of the small-scale freshwater aquaculture sector in six regions of Madagascar. READ MORE

  4. 3. Metagenomic insights into AMR distributions in freshwaters and soils

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Jay Håkansson; [2023]
    Keywords : AMR; metagenomics; freshwater; microbial ecology; soil; antimicrobial resistance;

    Abstract : Antimicrobial resistance (AMR) is rapidly becoming a public health issue, as more and more infectious bacteria become resistant to our known antibiotics. Suggested reasons for the proliferation of these strains are misuse and overuse of antimicrobials, especially on an industrial level, in agriculture, livestock and aquaculture. READ MORE

  5. 4. Mesoscale precipitation systems in the Tibetan Plateau region as represented by global reanalysis, regional downscaling and satellite data between 2001 - 2016

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Benjamin Holmberg; [2022-09-01]
    Keywords : Tibetan Plateau; monsoon; westerlies; mesoscale; convection; precipitation; climate modelling; global reanalysis; regional downscaling; spatial resolution; re-initialization; spectral nudging; convective parameterization;

    Abstract : The Tibetan Plateau (TP) is one of the world’s most important water towers. Convective precipitation systems play an important role by providing freshwater for the highly densely populated downstream regions, but they can also cause hazardous floods. READ MORE

  6. 5. A Comprehensive Review of the Factors Influencing the Environmental Impact of different Species bred in Closed Land-based Recirculating Aquaculture Systems

    University essay from Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)
