  3. 2. Tundra carbon cycling in relation to sea-ice decline in a warming Arctic

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Juliane Glinski; [2022]
    Keywords : sea-ice decline; warming Arctic; earlier growing season; arctic tundra; heterotrophic and autotrophic respiration; climate warming; Earth and Environmental Sciences;

    Abstract : We set out to investigate whether arctic tundra acted as a sink or source of carbon dioxide (CO2) between 1980-2014 and to relate changes in the net carbon balance to Arctic sea-ice decline. We want to understand how climate change and arctic warming influence arctic carbon cycling. READ MORE

  4. 3. Venture Capital flows to fintech innovators in Africa: How governmental policy and actions affect the ecosystem and capital sources

    University essay from Göteborgs universitet/Graduate School

    Author : Giove Lee; Franklin Amabo; [2021-07-06]

  5. 4. Evaluating drought impacts on ecosystem water use efficiency of three different boreal forest sites

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Tim Schacherl; [2021]
    Keywords : flux data; carbon uptake; water deficit; Sweden; drought resistance; nitrogen; Eddy covariance;

    Abstract : European boreal forests are the biomes most affected by climate change. For example, extreme weather events such as droughts are expected to become more frequent and severe. Especially in the summer months, droughts can drastically impact the carbon and water exchanges of boreal forests. READ MORE

  6. 5. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. READ MORE
