  1. 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 ekosystemvetenskap

    Author : Malin Ahlbäck; [2020]
    Keywords : Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Abstract : 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. 2. Assessing annual forest phenology: a comparison of Unmanned Aerial Vehicle (UAV) and phenocamera datasets

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Shangharsha Thapa; [2020]
    Keywords : Geography; Ecosystem Analysis; Near-surface Remote Sensing; UAV; Phenocamera; Forest Phenology; Phenophase; Seasonality; NDVI; GCC; Geomatics; Earth and Environmental Sciences;

    Abstract : Near-surface remote sensing platforms such as Unmanned Aerial Vehicles (UAVs) and phenocameras appear to be potential platforms for keeping track of seasonal dynamics at a local scale. This research focusses on extracting time series of different vegetation indices (VIs) from both platforms, computing seasonality events from them and comparing the results against spectral sensor data.

  3. 3. 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 miljöinstitutet

    Author : Elizabeth McNamee; [2020]
    Keywords : cement; concrete; decarbonizing technologies; novel alternative green cements concretes; demand-side; Earth and Environmental Sciences;

    Abstract : 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’.

  4. 4. 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 miljöinstitutet

    Author : Aziliz Le Rouzo; [2020]
    Keywords : Carbon Footprint; Green Roof Design; Carbon Sink; Cost-Effectiveness; Life cycle Cost-Benefit Analysis; Green Roofs; Earth and Environmental Sciences;

    Abstract : 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.

  5. 5. Analysing the controls over DOM quality in two contrasting sub polar marine environments

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Chiara Monforte; [2020]
    Keywords : DOM optical properties; Absorbance; Fluorescence; EEMs; Burdwood Bank; Beagle Channel; Earth and Environmental Sciences;

    Abstract : 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
