1. 1. The impact of CO2 fertilisation on foliage in West and East Africa

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gaetane Demyttenaere; [2023]
   Keywords : Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

   Abstract : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. READ MORE

3. 2. Monitoring deforestation in the Serranía de Chiribiquete in northern Colombian Amazon using time series analysis of satellite data

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Yuyang Qian; [2023]
   Keywords : Physical Geography and Ecosystem analysis; CCDC; Forest loss; Landsat; Sentinel-1; Change detection; NNP; FARC; Earth and Environmental Sciences;

   Abstract : Deforestation monitoring is of significant importance for the ecosystem, climate change,and policy-making. The availability of optical and synthetic aperture radar (SAR) satellite remote sensing images, along with the development of time series change detection methods, has contributed to the increasing popularity of time series analysis in forest disturbance monitoring.

4. 3. 3D geospatial data requirements for simulating noise using the Nord2000 model: Case study of the impact of building façade types and roof configurations on simulated traffic noise levels

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Soraya Hosseinvash Azari; [2023]
   Keywords : Physical Geography; Ecosystem Analysis; noise simulation; traffic; Nord2000 model; building façade types; roof configurations; geospatial data; 3CIM; SoundPLAN; acoustic properties; urban areas; 3D city model; Earth and Environmental Sciences;

   Abstract : The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. READ MORE

5. 4. Spatial downscaling of gridded soil moisture products using optical and thermal satellite data: the effects of using different vegetation indices

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Tómas Halldórsson Alexander; [2023]
   Keywords : Physical Geography and Ecosystem Analysis; Remote Sensing; Soil moisture; Downscaling; Vegetation index; Earth and Environmental Sciences;

   Abstract : Soil moisture (SM) plays an important role in the exchange of heat and water between the surface and atmosphere, impacting water and energy cycles and the climate. Satellite remote sensing offers a global-scale estimation of SM; however, the coarse resolutions of satellite SM products, typically ranging from 25-50 km, are unsuitable for regional analysis.

6. 5. Spatial-temporal responses of Arctic amplification to carbon-concentration and carbon-climate feedbacks in CMIP6 simulations

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Zhicong Xie; [2023]
   Keywords : Geography; Physical Geography; Ecosystem Analysis; Arctic amplification; Carbon cycle feedbacks; CO2 physiological effect; CMIP6; Earth and Environmental Sciences;

   Abstract : The Arctic is experiencing a phenomenon called Arctic amplification (AA) which has caused a rapid warming rate two to three times greater than that of the Northern Hemisphere (NH) or global in both observed and modelled data over the past few decades. Previous studies focused mostly on temperature and sea ice albedo feedbacks; however, the impacts of biosphere feedbacks especially from carbon cycle feedbacks, are largely underexplored. READ MORE
