1. 1. Reconstructing Past Climate by Using XRF and Loss of Ignition on Loess from Adventdalen, Svalbard : Rekonstruktion av tidigare klimat genom attanvända XRF analys och antändningsförlust på lössavlagringar från Adventdalen, Svalbard

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Albin Andreasson; Noa Lind; [2023]
   Nyckelord :Svalbard; loess soil; XRF; weathering; climate change;

   Sammanfattning : By analyzing the texture, composition and chemical composition of loess soils, the reconstruction ofpast climate regimes is enabled, which can improve our understanding of current and future climatechange. Properties such as grain size and composition, mineralogy, organic matter and chemicalcomposition can provide information about which environmental factors were present during thedeposition of the sediment, which can lead to a detailed picture of the climate history of a site.

3. 2. Arable Plant Diversity on Gotland, Sweden

   Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Rebecca Örnberg; [2023]
   Nyckelord :Arable plant; arable plants; arable diversity; arable; weed diversity; arable weed diversity; arable weed; arable weeds; plant diversity; diversity; drivers of diversity; field size; effects; crop type; standing crop; soil texture; organic farming; diversity; conventional farming; management; herbicides; rare plants; organic; biodiversity; field diversity; field margins; weed survey;

   Sammanfattning : Arable plant species diversity has been on a decline, with many species dependent on arable land becoming threatened. At the same time, attempts at defining the drivers of arable plant diversity have proven difficult and results are often contradictory. LÄS MER

4. 3. Potential Silvoarable Agroforestry Regions for Corylus avellana and Juglans regia in Scania, Sweden

   Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Isabella Svensson; [2023]
   Nyckelord :Silvoarable agroforestry; Corylus avellana; Juglans regia; Suitability assessment; Scania; Earth and Environmental Sciences;

   Sammanfattning : Conventional agriculture in Sweden is facing challenges with low resilience to a changing climate and decreased biodiversity. Silvoarable agroforestry is an alternative land use practice that contain a woody perennial and crop in the same field. LÄS MER

5. 4. A sensory evaluation of swidden rye (Secale cereale) – how the taste of history and geographical location can play part in a sustainable food production

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Amanda Jonsson; [2022]
   Nyckelord :Sustainable Development; Sensory science; Landrace; Terroir; Food system; Consumer science;

   Sammanfattning : Due to their resilience, durability, and broad genetic variations, increasing the production and consumption of landrace cereals has been highlighted as a solution to handle increasing environmental variability resulting from climate change. However, the consumption of landrace cereals remains low due to limited production and purchase availability for consumers. LÄS MER

7. 5. Effekter av markstruktur på tryckutbredning och packningsbenägenhet i åkermark : en jämförande fältstudie mellan konventionellt jordbearbetad åkermark och permanent bevuxen åkermark

   Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

   Författare :Gabriel Thor; [2022]
   Nyckelord :markpackning; hållfasthet; markstruktur; marktextur; direktsådd; reducerad jordbearbetning;

   Sammanfattning : Att gårdar blir större är en tydlig trend inom det svenska lantbruket. Med det följer även en större efterfrågan på större maskiner och redskap. Denna rationalisering medför en ökad risk för att åkermarken blir kraftigt packad och därigenom skadad, vilket på sikt kan leda till försämrad bördighet. LÄS MER
