    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Chinatsu Endo; [2021]
    Keywords : yellow rust; modeling; prediction; early warning; remote sensing; geography; geographical information systems; GIS; Agriculture and Food Sciences; Earth and Environmental Sciences;

    Abstract : Yellow rust (Puccinia striiformis f. sp. Tritici) is a crop disease caused by a fungus that regularly infects wheat and causes yield loss in Ethiopia. The disease has a significant impact on the country’s crop production, food security, health, and socioeconomic well-being. READ MORE

  2. 2. Remote sensing analysis of land cover/use conditions of community-based wildlife conservation areas in Tanzania

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Kharid Mwakoba; [2021]
    Keywords : geography; Geographical Information Systems; GIS; remote sensing; wildlife management area; Tanzania; Earth and Environmental Sciences;

    Abstract : Community based approaches to conservation in the developing world have generally been criticized for not meeting their goals of sustainable conservation and local development. Inadequate local participation and inequitable benefits sharing among others are some of the major concerns. READ MORE

  3. 3. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shangharsha Thapa; [2020]
    Keywords : Geography; Ecosystem Analysis; Near-surface Remote Sensing; UAV; Phenocamera; Forest Phenology; Phenophase; Seasonality; NDVI; GCC; Geomatics; Earth and Environmental Sciences;

    Abstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.

  4. 4. 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.
