1. 16. Knowledge and Data Driven Approaches for Hydrocarbon Microseepage Characterizations: An Application of Satellite Remote Sensing

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ali Al Farid; [2020]
   Keywords : Geography; Geographical Information Systems; Hydrocarbon Microseepage; PCA; Crosta; Band Ratio; MTMF; Weight of Evidence; SVM; Methane Fluxes; Remote Sensing; Satellite Image Classification; Earth Observation; Mineral Classifications; Machine Learning; Earth and Environmental Sciences;

   Abstract : Methane is a potent greenhouse gas that plays a major role in climate change. Significant uncertainty exists in the estimates of emissions from natural methane sources. This uncertainty in data is one of the primary scientific challenges in climate model. READ MORE

3. 17. How former arable fields with permanent grazing differ from managed semi-natural pastures in Sweden

   University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

   Author : Isolde Galin; [2019]
   Keywords : grasslands; former arable fields; species richness; species composition; semi-natural pastures; Ellenberg indicator values;

   Abstract : New farming needs and innovations have, over time, led to changes in land use. Arable fields have been turned into pastures and semi-natural pastures into arable fields. READ MORE

4. 18. Green Roof Performance in Cold Climates : A study on how different plants suited for the subarctic climate in northernSweden affects the performances of green roofs

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jonathan Hjelm; [2019]
   Keywords : Stormwater; Green roofs; Cold climate; Stormwater management;

   Abstract : Increased urbanization leads to an increasing amount of impervious surfaces and a decrease ofthe natural hydrological function. Urban stormwater does thus risk to create high surface flows which could damage the receiving water bodies (e.g. erosion) or the urban area itself (flooding). READ MORE

5. 19. Fältskiktsväxter i gran- och tallbestånd i södra Småland : en studie om indikatorvärden och hävdgynnade växter

   University essay from SLU/Southern Swedish Forest Research Centre

   Author : Johan Back; Christian Syk; [2018]
   Keywords : Ellenberg; hävd; indikatorvärden; tallskog; granskog; markanvändning;

   Abstract : Det svenska landskapet och dess markanvändning har förändrats kraftigt de senaste århundrandena, tät skogsmark har ersatt tidigare öppen mark och i södra Sverige har granen kommit att bli allt vanligare. Detta gör det intressant att undersöka vilka förutsättningar dagens skogslandskap skapar för växters livsmiljöer och om en signifikant skillnad mellan gran- och talldominerade skogar finns.

6. 20. Remotely sensed estimation of shrub encroachment : a case study on the Great Alvar, Öland, Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Franziska Weichert; [2018]
   Keywords : Great Alvar; shrub encroachment; species richness; growth rate; Earth and Environmental Sciences;

   Abstract : The increase of shrub extent in arid and semi-arid environments is reducing the species richness all over the globe. This process of shrub encroachment was found to result from changes in anthropogenic land use, especially from too high or too low grazing intensity. READ MORE
