  1. 1. Future climate suitability of shade trees in cocoa agroforestry systems in West Africa and shade tree diversity’s impact on farm microclimate : A Minor Field Study

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Jonna Halonen; [2023]
    Nyckelord :species distribution modeling; cocoa agroforestry; shade trees; West Africa; microclimate; distributionsmodell; kakaoskogslantbruk; skuggträd; Västafrika; mikroklimat;

    Sammanfattning : Shade trees’ implementation into cocoa agroforestry systems in tropical West Africa has proven to have a high potential in increasing farm resilience and mitigating climate change. However, no studies have yet examined the potential future climate suitability for shade trees in the region, which is important when deciding which shade trees to implement. LÄS MER

  2. 2. Importance of Snow in Alpine Plant Ecology : And Remote Sensing Applications in Species Modeling

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Eva Meyer; [2022]
    Nyckelord :;

    Sammanfattning : Global warming, with pronounced increases toward the poles and high latitudes, has impacts on alpine vegetation. If snow patterns change in response to global warming, snow parameters are predictors of interest in alpine plant species distribution and traits modeling because snow is known to strongly control the local growing conditions of alpine plants.

  3. 3. Assessment of hydropower mitigation measures for fish habitat rehabilitation with a coupled eco-hydraulic model : A case study on the Skålan-Äldern stretch

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Francesca Polato; [2021]
    Nyckelord :hydropower; mitigation measures; ecological flow assessment; hydraulic modeling; physical habitat models; vattenkraft; begränsande åtgärder; ekologisk flödesbedömning; hydraulisk modellering; fysiska livsmodeller;

    Sammanfattning : In the past century, hydropower development in Sweden has been facilitated by the lack of appropriate environmental legislation. This exploitation has resulted in the current poor ecological status of most Swedish water bodies affected by hydropower, and in the need for new policies that reflect the 2000 European Water Framework Directive.

  4. 4. Transient Flow Simulations in Exhaust After Treatment Systems

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :John Walder; [2020]
    Nyckelord :Computational Fluid Dynamics; exhaust after treatment system; ammonia mixing;

    Sammanfattning : The exhaust after treatment system is responsible for removing particulates and contaminants from the exhaust gases. The flow entering the SCR, a catalyst utilizing ammonia to reduce NOx emissions, was studied. The quality and distribution of flow entering the SCR plays an important role in the efficiency of the systems. LÄS MER

  5. 5. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Chen Luo; [2020]
    Nyckelord :acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Sammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.
