1. 26. Monitoring wetland cover changes during the past two decades within the protected areas of the Sudd wetland in South Sudan using MODIS data

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

   Författare :Charlotta Ruuskanen; [2021]
   Nyckelord :Physical Geography and Ecosystem analysis; MODIS; NDVI; Sudd Wetlands; Wetland Cover Classification; White Nile Hydrology; Armed Herder-Pastoralist Conflict analysis; Earth and Environmental Sciences;

   Sammanfattning : The Sudd wetland, situated along the White Nile in the Republic of South Sudan, is recognized internationally for its unique environmental features. The distinctive ecological characteristics have resulted in the creation of numerous nature reserves in efforts to conserve the habitats and ecosystem services provided. LÄS MER

5. 29. Topographic controls of drought impact on Swedish primary forests

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

   Författare :Johanna Asch; [2021]
   Nyckelord :Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

   Sammanfattning : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. LÄS MER

7. 30. Behind the early warning: Improving impact-based forecasting of riverine floods in Malawi using passive microwave remote sensing

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

   Författare :Lone Mokkenstorm; [2021]
   Nyckelord :Physical Geography; Ecosystem Analysis; Early Warning; Riverine Floods; Humanitarian Work; Impact-based Forecasting; Malawi; Earth and Environmental Sciences;

   Sammanfattning : This thesis investigates whether freely available, coarse-resolution, Passive Microwave Remote Sensing (PMRS) data (37 GHz) can be effectively used for early warning systems for floods in Malawi. The Shire River Basin in Chikwawa and the smaller-scale North Rukuru River Basin in Karonga were studied using two alternative, ratio-based satellite indices that make use of the signal difference between wet and dry pixel cells: The m index and the rcmc index.
