Carbon storage capacity in arable land and pasture across Lund Municipality in regard to management techniques
(2024) In Student thesis series INES NGEK01 20241Dept of Physical Geography and Ecosystem Science
- Abstract
- Due to the increasing CO2 concentrations in the atmosphere caused by anthropogenic greenhouse gas emissions, there is a need for adaptations and mitigations to climate change. Not only is a drastic reduction of emissions necessary, but the uptake of CO2 from the atmosphere needs to be increased and stored long-term. One of the more efficient mitigation strategies to reduce CO2 concentrations in the atmosphere is to increase the storage of carbon (C) in soils. This study aims to calculate the C storage capacity in Lund municipality in arable land and pasture today and examine the change of C sequestration if enhanced management strategies were implemented. This will be done by using different scenarios in time and space.

Not only is a drastic reduction of emissions necessary, but the uptake of CO2 from the atmosphere needs to be increased and stored long-term. One of the more efficient mitigation strategies to reduce CO2 concentrations in the atmosphere is to increase the storage of carbon (C) in soils. This study aims to calculate the C storage capacity in Lund municipality in arable land and pasture today and examine the change of C sequestration if enhanced management strategies were implemented. This will be done by using different scenarios in time and space.
To conduct this study, a C storage capacity template from “Svensk Kolinlagring'” (Swedish Carbon Capture) was used. As arable lands and pastures have a high CO2 storage capacity in Lund municipality, they were used in this study. Through data from “Lantmäteriet” (The Land Survey) and “Jordbruksverket” (The Swedish Agricultural Agency), it was possible to detect and locate arable land and pasture in the municipality. Through this, a base scenario was created with the aim to represent the C storage in the best way possible. Then different scenarios were created and applied for different management techniques derived from the C storage capacity template. The different scenarios also included change in area and over time. The differences were then studied and the consequences they brought were discussed.
The results showed that so-called Stacked management methods have the highest potential to increase soil C uptake in the area. The Single management methods also showed an increase of C sequestration compared to the base scenario, but not to the same extent as the Stacked management methods. However, implementing new management techniques can be difficult and several other aspects can conflict, such as economic and land use interests. Long term, C sequestration in the soil will yield economic benefits. However, this is rather the opposite in the short-term perspective. Further studies are needed to deepen the knowledge even more for municipalities to mitigate their CO2 emissions. For example, municipality-specific studies to account for local conditions, such as soil type and cultivated area. (Less)
