  1. 6. Spatio-temporal drought characteristics in the Limpopo basin from 1918 to 2018 - A case study based on analysis of the Standardized Precipitation Evaporation Index (SPEI)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sandra Domingos Sambo; [2021]
    Keywords : rdought; Standardized Precipitation Evapotranspiration Index; Limpopo River basin; Normalized difference vegetation index; Mann-Kendall Test; Correlation analysis; Earth and Environmental Sciences;

    Abstract : The identification of the characteristics of drought are of great importance in water resources planning and management. This study explored the characteristics of drought at Limpopo River Basin (LRB) from 1918 to 2018. READ MORE

  3. 7. Agriculture monitoring using satellite data

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Graff Erik; [2021]
    Keywords : Sentinel; satellite; agriculture; monitoring; dynamic time warping; remote sensing;

    Abstract : As technology advances, the possibility of using satellite data and observations to aid inagricultural activities comes closer to reality. Swedish farmers can apply for subsidies for their land in which crop management and animal grazing occurs, and every year thousands of manual follow-up checks are conducted by Svenska Jordbruksverket (Swedish Board of Agriculture) to validate the farmers’ claims to financial aid.

  4. 8. Precipitation variability modulates the terrestrial carbon cycle in Scandinavia

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Ella Ek; [2021]
    Keywords : Terrestrial carbon cycle; NDVI; Precipitation variability; EOF analysis; Scandinavia; Terrestra kolcykeln; NDVI; Nederbördsvariation; EOF analys; Skandinavien;

    Abstract : Climate variability and the carbon cycle (C-cycle) are tied together in complex feedback loops and due to these complexities there are still knowledge-gaps of this coupling. However, to make accurate predictions of future climate, profound understanding of the C-cycle and climate variability is essential. READ MORE

  5. 9. Impact of fire and frost drought events on vegetation greenness and albedo in Subarctic Scandinavia

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Elin Backström; [2021]
    Keywords : Physical Geography and Ecosystem analysis; Vegetation Greenness; Albedo; Fire; Frost Drought; Earth and Environmental Sciences;

    Abstract : With climate change, the frequency in climate extremes such as drought, heavy rainfalls, and extreme temperatures is predicted to increase. These extremes can potentially stress and damage vegetation over large areas, leading to altered carbon cycle, vegetation greenness, albedo, and shifted species composition. READ MORE

  6. 10. Vegetation-climate interactions in California – an in-depth analysis on the influence of climatic events across different Californian biomes

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Felipe Fileni; [2021]
    Keywords : droughts; climate vegetation interactions; SPEI; NDVI; California;

    Abstract : It is widely accepted that climate variability is a key driver of vegetation productivity. Yet, there are discrepancies on the ideal timescales of climatic events and vegetation response. The work herein attempts to clarify how those variables interact in the region of California. READ MORE
