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. Propelling the Commercialization of ‘Novel Cements’: An investigation of demand-side factors to accelerate decarbonizing technologies within the cement industry
University essay from Lunds universitet/Internationella miljöinstitutetAbstract : Accounting for approximately 8% of global CO2 emissions, the cement industry is one of the greatest contributors to climate change, despite the lack of focus on this sector in popular discourse. Deep cuts in this sector are challenging to achieve due to necessitated alteration of material components and formulation of the traditional product in addressing non-energy related ‘process emissions’.

3. Re-thinking green roof design : The prospect of a carbon sink structure investigated through a life cycle cost-benefit analysis
University essay from Lunds universitet/Internationella miljöinstitutetAbstract : Green Roofs (GRs) have been used worldwide as a solution for greening cities, while providing useful services to society such as storm water management, improved air quality, energy savings, and increased biodiversity, to name a few. However, the environmental impact of their structure has been understudied, and more importantly, the carbon cost related to the use of materials that have a high carbon footprint has received little to no attention.

4. Analysing the controls over DOM quality in two contrasting sub polar marine environments
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. READ MORE

5. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. READ MORE
