1. 26. Vegetation-climate interactions in California – an in-depth analysis on the influence of climatic events across different Californian biomes

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Felipe Fileni; [2021]
   Nyckelord :droughts; climate vegetation interactions; SPEI; NDVI; California;

   Sammanfattning : It is widely accepted that climate variability is a key driver of vegetation productivity. Yet, there are discrepancies on the ideal timescales of climatic events and vegetation response. The work herein attempts to clarify how those variables interact in the region of California. LÄS MER

3. 27. Multi-scale topography assessment for site-specific drought management in Sweden

   Master-uppsats, SLU/Dept. of Soil and Environment

   Författare :Karl Knaebel; [2021]
   Nyckelord :drought; topography; precision agriculture; Sentinel-2; DSS;

   Sammanfattning : Globally, as well as in Sweden, the occurrence of droughts is expected to increase due to global warming. The drought summer of 2018 revealed the vulnerability of Sweden’s agriculture – with cereal yield losses of up to 50 %. Subsequently, the development of more resilience crop production systems to mitigate future droughts is required. LÄS MER

4. 28. Effects of armed conflict on forest cover and vegetation seasonality in Cambodia

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

   Författare :David Ebert; [2021]
   Nyckelord :conflict; forest cover; vegetation seasonality; NDVI; remote sensing; Cambodia; Earth and Environmental Sciences;

   Sammanfattning : Armed conflicts have definitive wide-ranging and diverse impacts on the environment. This thesis examines associations between conflict and land cover change in Cambodia, focusing on the last decade (1989 - 1998) of a thirty-year long Civil War. LÄS MER

5. 29. Remote sensing analysis of land cover/use conditions of community-based wildlife conservation areas in Tanzania

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

   Författare :Kharid Mwakoba; [2021]
   Nyckelord :geography; Geographical Information Systems; GIS; remote sensing; wildlife management area; Tanzania; Earth and Environmental Sciences;

   Sammanfattning : Community based approaches to conservation in the developing world have generally been criticized for not meeting their goals of sustainable conservation and local development. Inadequate local participation and inequitable benefits sharing among others are some of the major concerns. LÄS MER

7. 30. Exploring Spatiotemporal Relationships between InSAR-derived Land Subsidence and Satellite-based Hydrological Variables

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

   Författare :Yixin Zhang; [2021]
   Nyckelord :InSAR; Shabestar; subsidence; groundwater; hydrological variables; LSTM; Sentinel-1A; Geomatics; Technology and Engineering; Earth and Environmental Sciences;

   Sammanfattning : Shabestar basin in the East Azerbaijan province, Northwest Iran, where irrigation is the main groundwater consumer, has experienced large-scale subsidence and groundwater deletion, which poses a threat to the local agricultural activities, economic development, and food security. With the emergency of mitigating the risk, satisfying future demand for groundwater, and improving resilience considering climate change, this study proposes a satellite-based approach to explore the spatio-temporal relationships between measured subsidence and hydrological variables in the basin to assist groundwater management strategy.
