  1. 1. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tómas Halldórsson Alexander; [2023]
    Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

    Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

  3. 2. Correlation between Normalized Difference Vegetation Index (NDVI) and in vitro organic matter digestibility (IVOMD) of reindeer pasture plants : Korrelation mellan Normalized Difference Vegetation Index (NDVI) och smältbarhet av renbetesväxter i vomvätska in vitro (VOS)

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Jannica Helmersson; [2023]
    Keywords : Normalized Difference Vegetation Index; NDVI; in vitro organic matter digestibility; IVOMD; VOS; caribou; Rangifer tarandus; reindeer pasture plants; drone;

    Abstract : Renen livnär sig på många olika betesväxter och den följer växtfenologins utveckling under barmarkssäsongen, vilket resulterar i högkvalitativt foderintag. Levande växtbiomassa kan uppskattas på landskapsnivå genom att använda vegetationsindex som värderar vegetation utifrån spektrala mätningar. READ MORE

  4. 3. Tree growth and field vegetation in forest edge zones on a property in southeast Sweden

    University essay from Linnéuniversitetet/Institutionen för skog och träteknik (SOT)

    Author : Pieter van Tongeren; [2023]
    Keywords : tree growth; diversity; field vegetation; edge zones; edge effect;

    Abstract : Summary  In the 1990s a new way of thinking about forestry started. One of the effects of the changing silvicultural practices was that the size of clearcuts became smaller. As the felling areas were reduced in size, the areas where young and older forest meet grew, with this also the occurrence of edge zones increased. READ MORE

  5. 4. Using NDVI Time-Series to Examine Post-fire Vegetation Recovery in California

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Viktor Wu; [2022]
    Keywords : fire; California; NDVI; land cover; vegetation; post-fire recovery;

    Abstract : Over the past couple of decades, fires have experienced changes on a global scale. These changing fire regimes point to an alarming direction where fire-dependent ecosystems are experiencing a decline in burned area, while fire-independent ecosystems are experiencing an increase.

  6. 5. Lantsorter och moderna sorter av vårvete : effekt av gödsling och miljö

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Anders Lööv; [2022]
    Keywords : lantsorter; vårvete; lantvete; kulturspannmål; ekologisk odling;

    Abstract : Lantsorter har tillskrivits flera goda agronomiska egenskaper som att vara anpassningsbara till rådande odlingsförutsättningar, effektivt vatten- och näringsupptag, förmåga att stå emot hög värme och torka, samt god ogräskonkurrensförmåga. Kvalitetsegenskaper som protein- och glutenhalt beskrivs vara särskilt höga och bakningsegenskaperna goda. READ MORE
