  1. 1. 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

  2. 2. ENSO teleconnections - Analysis of time lag between tropical Pacific sea surface temperature and climate and vegetation anomalies

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jiri Navrátil; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; ENSO; teleconnections; climate; NDVI; Earth and Environmental Sciences;

    Abstract : El Niño-Southern Oscillation (ENSO) affects weather and climate in regions spread all around the Earth via teleconnections. While quite a lot of research has been done on recognizing what regions are affected by these and what is the sign of the associated temperature, rainfall and vegetation anomalies, not that much attention has been paid to the timing of the impacts with respect to the ENSO state.

  3. 3. Urbanisation by expulsion : the political economy of landed property in Asunción, Paraguay

    University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

    Author : Maiwenn Jensen-Guenec; [2020]
    Keywords : Paraguay; real estate development; land inequality; urban development; Marxian political economy; Social Sciences;

    Abstract : Although much research has been conducted regarding the uneven distribution of land in developing countries, such work tends to focus on rural land dispossession. In turn, land inequality in urban property markets of vulnerable economies remains somewhat understudied. READ MORE

  4. 4. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Alexis Cazorla; [2020]
    Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

    Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

  5. 5. A Spatially Explicit Agent-Based Model of Human-Resource Interaction on Easter Island

    University essay from KTH/Numerisk analys, NA

    Author : Peter Steiglechner; [2020]
    Keywords : Agent-based modelling; applied mathematics; socio-economic modelling; Agentbaserad modellering; tillämpad matematik; socioekonomisk modellering;

    Abstract : The history of Easter Island, with its cultural and ecological mysteries, has attracted the interests of archaeologists, anthropologists, ecologists, and economists alike. Despite the great scientific efforts, uncertainties in the available archaeological and palynological data leave a number of critical issues unsolved and open to debate. READ MORE
