1. The impact of CO2 fertilisation on foliage in West and East Africa
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : 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

2. Post-Fire Vegetation Recovery Monitoring using MODIS Time Series: A Case Study in California
University essay from KTH/GeoinformatikAbstract : Human-caused forest fires have increased in magnitude and frequency, affecting global vegetation and requiring a re-evaluation of fire regimes. Changing fire regimes have led to reduced burned areas in fire- dependent ecosystems and increased areas in fire-independent ecosystems, resulting in changes in land cover and posing a threat to native plant communities.

3. Changes in July albedo and its relationship with EVI over the last two decades in the Swedish alpine region
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Vegetation in the subarctic is expected to respond to climate warming as its growth becomes less temperature limited. This has previously been recorded in the form of treeline advances and increasing shrub cover. Changes in vegetation cover may accelerate warming due to a decrease in summer albedo, in what is termed surface albedo feedback. READ MORE

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 ekosystemvetenskapAbstract : 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.

5. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. READ MORE
