  1. 1. Impact from Tourism on Vegetation Greenness in Yellowstone National Park

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Fenja Runfors; [2023]
    Keywords : Yellowstone National Park; NDVI; Remote Sensing; Tourism; Earth and Environmental Sciences;

    Abstract : Tourism has increased drastically during the last decades in Yellowstone National Park, from nearly 20 000 visitors in 1910 to almost five million visitors in 2021. Yellowstone is an important ecosystem with unique wildlife, and geological and cultural history. READ MORE

  3. 2. Spatiotemporal changes in Gothenburg municipality's green space, 1986 to 2019

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Kristin Blinge; [2021-04-01]
    Keywords : NDVI; multitemporal change analysis; incremental change; urbanization;

    Abstract : As the world’s population is becoming increasingly more urban the infrastructure expands to accommodate the inhabitants’ needs. In a dense urban environment green space has an important function since it provides vital ecosystem services, contributes to recreational and cultural values and is essential for biodiversity.

  4. 3. 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. 4. 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. 5. 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
