1. 11. Mapping time-series evapotranspiration for agricultural applications

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Erik Jan Bootsma; [2021]
   Nyckelord :;

   Sammanfattning : Fresh water provides a range of essential services and is often used for irrigation purposes. Decreasing precipitation and increasing temperatures caused by climate change together with increased usage by humans has put these resources under stress, especially in relatively dry areas.

3. 12. Assessment of Urban Sprawl in Mowe/Ibafo Axis of Ogun State using GIS Capabilities

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

   Författare :Haruna Jimoh; [2020]
   Nyckelord :GIS; Urban sprawl; expansion; assessment; Shannon’s entropy; Mowe Ibafo; Earth and Environmental Sciences;

   Sammanfattning : Urban Sprawl is one of the challenges to urban development in many nations. Different aspects of the phenomenon have been researched with a view to providing solutions to myriad of ills attributed to it. For any meaningful intervention, however, assessment of development to ascertain sprawl is essential. LÄS MER

4. 13. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

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

   Författare :Julika Wolf; [2020]
   Nyckelord :Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

   Sammanfattning : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. LÄS MER

5. 14. Impact of Carbon Sinks on Urban Heat Island Effects : Assessment Using Satellite Data in Water Scarce Region of the Thesis

   Magister-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

   Författare :Nadine Macauley; [2020]
   Nyckelord :Urban Heat Island; Carbon Sinks; Qatar; Satellite Remote Sensing; Al Bayt Stadium; Energy Systems; Energy Use; Sustainability; LST; Hot Arid Climate;

   Sammanfattning : Urbanization modifies the thermal characteristics of the land and makes way for a succession of transformations in the urban environmental system. This phenomenon, known as Urban Heat Island (UHI), is characterized by elevated temperatures in urban areas that negatively impact on the quality of life and environment in urban areas including, increased emissions of Green House Gases (GHGs) and rising energy consumption.

7. 15. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden

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

   Författare :Shuo Yang; [2019]
   Nyckelord :Physical Geography and Ecosystem Analysis; Remote Sensing; Bark Beetle; Insect Detection; Sentinel-2; Forest Health; Maximum Likelihood; Random Forest; Spectral Signature; Vegetation Indices; Earth and Environmental Sciences;

   Sammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER
