6. Tidig detektering avgranbarkborreangrepp med hjälp avfjärranalys via Sentinel-2
Kandidat-uppsats, Högskolan i Gävle/DatavetenskapSammanfattning : Granbarkborre är en av Sveriges mest destruktiva skadeinsekter som angriper granskog. Insekten har medfört förödande konsekvenser för granskog, framför allt sedan2018 där stora arealer granskog nästan har eliminerats. Insekten trivs i varmt ochtorrt klimat. LÄS MER
7. Early-stage detection of bark beetle infested spruce forest stands using Sentinel-2 data and vegetation indices
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The European spruce bark beetle is an insect that is often referred to as a pest. Responsible for the destruction of over 150 million m3 of Norwegian spruce forest in Europe over the last 50 years makes this insect one of the major disturbances to the forest industry. LÄS MER
8. Assessing the impact of post-fire restoration interventions using spectral vegetation indices: A case study in El Bruc, Spain
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Ecological restoration has become an increasingly used practice to revert degraded land and mitigate the effects of extreme events in vulnerable biomes such as drylands. Methods to improve the assessment of these restoration interventions are essential to ensure their success, optimize resources and identify improvement aspects for future interventions. LÄS MER
9. Dynamics of net primary production and food availability in the aftermath of the 2004 and 2007 desert locust outbreaks in Niger and Yemen
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The knowledge of desert locust plagues goes back to biblical times but it is just as relevant in 2020 with an ongoing outbreak in East Africa and the Middle East. The locusts pose a threat to agriculture, and by extent food availability, due to their high appetite, diverse diet and ability to migrate long distances in large swarms. LÄS MER
10. Using remote sensing and land abandonment as a proxy for long-term human out-migration. A Case Study: Al-Hassakeh Governorate, Syria
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The topic of human migration and displacement has become more important in recent years and will continue to do so in the following decades. Voices become louder claiming that climate change is a driving factor for increased displacement and migration. LÄS MER
