1. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. READ MORE

2. NDVI time series analysis for desert locust outbreak detection and quantification analysis of its impact on vegetation productivity of Sahel
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : It has been shown that the semi-arid environment of the Sahelian belt plays an important role in the global carbon uptake as the fluctuation of its primary productivity can be determinant for the global carbon uptake. The insect Schistocerca gregaria commonly known as the desert locust is a disturbance factor that can affect the vegetation productivity for consecutive seasons. READ MORE

3. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. READ MORE

4. Early season BVOC emission for young potted Norway spruce (Picea abies)
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Biogenic volatile organic compounds (BVOC) are emitted naturally from the biosphere to the atmosphere and are a part of the global carbon emissions. BVOCs are contributing to around 5-10% of the total net carbon exchange to the atmosphere. READ MORE

5. Studying the Dissociation Dynamics of Carbon Dioxide
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratorietAbstract : Small molecules, and their fragmentation to smaller constituents upon excitation, are often used to understand how the bonds in a molecule are formed and how they break. One of such widely studied model molecule is CO2. This study aims at extending the knowledge of dissociation of carbon dioxide by measuring also the negatively charged fragments. READ MORE
