We are daily moving in different landscapes for various reasons; sometimes we are looking for specific activities and sometimes just to move from one place to another. Common for this is the affect the landscape can have on us and how it gives us different experiences. In this essay I seek answers to what is important for people when they visit the nature for recreational purposes. What factors do
Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel
It is impossible to conceive our modern world without plastics. Since the mass production of plastics began, humanity has produced around 8 billion tons of plastic waste, and only 9% has been recycled. Terephthalic acid polymers such as poly(ethylene terephthalate) (PET) have been massively produced over the last years thanks to their characteristics and applications. Due to their limited biodegra
Cities today globally face significant problems in the context of the climate crisis. Firstly, in terms of resilience in enduring future challenges – urban heat islands, increasingly frequent flooding, supply chain disruptions, sea level rise among others. Secondly, in terms of contributing to said crisis, through carbon emissions, the erosion of biodiversity through sprawl, overconsumption, and c
Bacterial cellulose (BC) is a versatile and biocompatible polysaccharide produced by bacteria, with Komagataeibacter xylinus being the model species for its production. This polymer has unique properties that make it valuable in several applications, including as a rheology modifier in cosmetics. Cellugy, a Danish start-up, produces EcoFLEXY, a BC-based rheology modifier that enhances the viscosit
The last mass-extinction event happened over 65 million years ago when an asteroid collided with earth, resulting in the loss of 76% of all species. Scientists now warn that we are on the precipice of a new mass-extinction, the responsibility of which can be placed entirely on one species, the homo sapiens. While some species of birds, bats, and arthropods are especially vulnerable, we are all int
For many years, outdoor localization has been dominated by Global Positioning System (GPS) and other GNSS-based methods. While GPS provides global coverage and usually high accuracy, it has its limitations. GPS has lower accuracy in areas with many obstructions, such as buildings or trees, and is power consuming compared to other localization methods. Therefore, GPS may not be the best localizatio
Our decisions from the past affect the present time. The same is true of the decisions we make today. How do we want to see our local environment in the future? In the western part of Iceland there is an island called Brákarey. Brákarey is connected via bridge to the town of Borgarnes. Brákarey has played a variety of roles over the past years, but transport of people and goods was one of its bigg
This thesis investigates how place can be understood through assemblage theory and what that implies for the understanding of human relation to place. The framework has been widely used outside and within human geography, at a few instances related to place. Exploring place as assemblage is done through a case study of S:t Pauli cemeteries in Malmö. Main methods are walk along interviews and obser
III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a
Introduction: This study evaluated lipid identification using mass spectrometry. Background: Three main modes of acquisition are used in mass spectrometry of lipids; data-independent acquisition (DIA), data-dependent acquisition (DDA) and targeted acquisition. DIA is the most including one, yielding a complete but complex data set, while targeted is the least including one, basing acquisition on
This thesis clarifies how the management of contaminated excavation soils can be made more sustainable and circular by applying in-situ techniques. Its aim is to map existing and emerging remediation methods, identify technical, legal and economic obstacles, and quantify potential climate and cost benefits, giving industry stakeholders a sound basis for increasing local treatment and reuse of soil
Due to the climate crisis we are facing, we can no longer consider current construction methods, which contribute to 40% of global CO₂ emissions, as an alternative to building. Vernacular architecture, in comparison, offers a sustainable alternative. People have experimented with this approach to designing, constructing, and living throughout time. This system essentially stands for maximizing eff
Forest ecosystems are important actors in climate change mitigation strategies through their abilities to act as both carbon sinks and sources. The commonly used forest management strategy of clearcutting has been suggested to be paired with large greenhouse gas emissions, increasing the need for research on the climate effect from alternative management strategies. Rumperöd forest is managed thro
This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin
