The actual concept of food security focuses on four food security dimensions: food availability, food access, food utilization and food stability of which eight indicators were identified for this study. The study aims to evaluate vulnerability to chronic food and nutrition insecurity, one of the food stability types, in Ethiopia; and examines the relationship between four food security dimensions
The industrial sector of Sweden used 136 TWh of energy 2022 out of which the agricultural sector used 6.09 TWh. The goal of the country is to become 50% more energy efficient by 2030 compared to 2005. Furthermore, Sweden’s long-term target is to achieve net zero greenhouse gas emissions by 2045. From 2005-2022 the total energy use of the agricultural sector has been reduced by 16% but previous stu
This master’s thesis explores the sustainability and the circularity of industrial packaging of components for complex electronic products. The research aims to gain insight into the structure of the packaging system between the suppliers and the manufacturers (EMS) and evaluate its circularity to identify the opportunities and challenges for future improvement. The study examines the packaging

Fourier transform infrared spectroscopy techniques were used to study the kinetics of gas-phase reactions of three lactones, γ-valerolactone (GVL), 2(5H)-furanone (2(5HF) and 3-methyl-2(5H)-furanone (3M2(5H)F) with Cl atoms, OH radicals and O3 respectively. The experiments were performed in a photochemical reactor at a total pressure of 700 Torr at room temperature (298±2 K). Both relative rate an
This study is an assessment of the functioning of the three year old Transparency Mechanism. The mechanism has a surveiling role in the WTO of the Regional Trade Agreements (RTA). Formation of RTAs has been increasing rapidly during the latest twenty years, causing a tension in the multilateral trading system. RTAs give more preferable treatment to parties within the agreement than to trading part
This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. The thesis begins with a literature rev
There is a need to identify leverage points for a broader cultural transformation that addresses the root causes of the nature-climate emergency. Music and art festivals are creative free spaces outside the everyday workings of society that have the potential to plant the seeds of a holistic, sustainable future. I combine prefiguration and the three spheres of transformation in a framework to inve
Understanding greenhouse gas fluxes in semi-arid ecosystems is critical for improving our understanding of biogeochemical cycles, particularly in underrepresented regions like the African Sahel. In these landscapes, greenhouse gas exchange arises from ground, trees, and water ponds, and is further shaped by environmental conditions and grazing. The carbon dioxide, methane, and nitrous oxide fluxes
Litter decomposition is a source of gaseous products, including volatile organic compounds (VOCs) to the atmosphere. The quantity and the chemical composition of the VOC blends released from litter vary between plant species and depend on environmental factors and litter microbial communities. Here, we assessed VOC release from decomposing litter in a 3-year incubation conducted in a climate manip
Introduction: Implementing new treatment regimens entails a learning phase with a concomitant risk of suboptimal results. High caseload has generally been shown to improve results in complex surgical procedures. This study aimed to evaluate results of Cytoreductive Surgery (CRS) and Intraperitoneal Chemotherapy (IP), given as Early Postoperative Intraperitoneal Chemotherapy (EPIC) or Hyperthermic
Understanding regional variation in public transport preferences is essential for designing efficient mobility systems. This study examines the stability of preferences for both traditional public transport and demand-responsive transport across three Swedish regions–Stockholm (urban), Skåne (intermediate), and Värmland (rural)–using discrete choice experiments. The analysis focuses on key service
Questions: Earth observation is an important tool in biological monitoring. Previous studies have shown that variation in grassland canopy reflectance can explain gradients in plant community composition. However, there is a need for methods that allow the interpretation of the overall spectral signal of complex grassland vegetation in terms of existing knowledge about individual species' habitat
Transpiration drives up to 40 % of terrestrial precipitation, with forests playing a critical role. This study combines long-term sap flow measurements and surface-based cloud observations to examine how different clouds affect tree transpiration across boreal and temperate European forests. Under specific cloudy conditions, sap flow can exceed clear-sky levels, reflecting distinct radiation effec
The mountain front recharge (MFR) process significantly influences the movement of water and dissolved organic carbon (DOC) in alpine catchments. However, no existing watershed models can adequately simulate this process, hindering accurate quantification of streamflow and DOC dynamics. To address this gap, this study explicitly incorporated the MFR process into a watershed-scale integrated water–
PurposeTo explore the cultural embeddedness of (un)welcome experiences among ethnically marginalized consumers in retail spaces.Design/methodology/approachDrawing on Arjun Appadurai's notion of the ethnoscape, the study is empirically grounded in critical-incident interviews with consumers from multiethnic backgrounds in Sweden.FindingsThree dimensions through which (un)welcome is negotiated are i
The rise of solo living presents significant social and environmental challenges, particularly in high-income countries like Denmark where nearly half of households are single occupancy. This study explores the social dynamics driving the trend towards living alone through in-depth interviews with 23 individuals living alone in Denmark. Pathways to solo living include urban relocation, aging out o
How environmental and climate challenges that often evoke strong negative emotions are communicated and responded to is of great importance. These include forest fires, plastic pollution and flooding that can produce fear, sadness and powerlessness. Images are important to this communication, yet how these challenges are captured through visual communication tools and to what outcomes requires fur
Canopy decline is increasingly prevalent in high-elevation snow gum (Eucalyptus pauciflora) forests across the Australian Alps. This phenomenon, known as snow gum dieback, is associated with infestations by the wood-boring beetle, Phoracantha mastersi. The larvae of this beetle create feeding galleries in the tree trunk, leading to the exudation of kino, a tannin-rich resin produced as a defense r
We present PyeLink and SyeLink, two complementary open-source Python tools for running eye-tracking experiments and parsing data from SR Research Ltd. EyeLink eye tracking hardware. PyeLink simplifies experiment creation through plug-and-play support for multiple display backends (Pygame, PsychoPy, Pyglet) while enabling two features not available in existing tools: recording data during calibrati
