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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

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

    Sammanfattning : 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

    Master-uppsats, Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Numerisk analys, NA

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

    Sammanfattning : 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. LÄS MER

  5. 5. Skogsbränder, en fara eller icke fara? : En studie om framtidens skogsbränder, dess konsekvenser och bekämpning

    Kandidat-uppsats, Karlstads universitet/Institutionen för sociala och psykologiska studier (from 2013)

    Författare :Toni Issa; [2020]
    Nyckelord :Forest fire; Risk; Fire risk; Physical planning; Risk analysis; Skogsbrand; Risk; Brandrisk; Fysisk planering; Riskanalys;

    Sammanfattning : In 2018, forest fires occurred in Sweden, which put high pressure on rescue services and society. Several parts of the country were subject to a fire ban. The purpose of the document study is to investigate whether forest fires could become a continuous danger for municipalities and their inhabitants in the future. LÄS MER
