  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. 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

  4. 4. When do we ask the Children? - A STUDY ON CHILDREN'S PARTICIPATION IN SWEDISH MUNICIPAL PLANNING

    University essay from Örebro universitet/Institutionen för humaniora, utbildnings- och samhällsvetenskap

    Author : Moa Elfström; [2020]
    Keywords : Children’s Geography; Social Sustainability; Children’s Participation; Comprehensive Planning; Convention on the Right of the Child; Planners Role; Norway;

    Abstract : This thesis discusses how children's perspectives are implemented in the municipality's physical planning in Sweden in relation to the statutory UN Convention on the Rights of the Child. The thesis seeks to answer how the planners express their views on the participation, as well as their views on the child and childhood. READ MORE

  5. 5. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Evangelos Oikonomopoulos; [2020]
    Keywords : Physical Geography and Ecosystem Analysis; Primary Productivity; Desert Locust; NDVI; Time Series Analysis; Outbreak Detection; Food Security; Sahel; Insect Disturbances; GEM; Earth and Environmental Sciences;

    Abstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE
