Boreal forests store the majority of their carbon in the soil and play an important role in the global carbon cycle. However, the mechanisms that control carbon storage in boreal soils are not well understood. In recent studies, there has been a specific focus on how ectomycorrhizal (ECM) fungi influence carbon dynamics in boreal forests, particularly through their nitrogen acquisition. A major pa
Large amounts of plastic in the oceans originate from mismanaged plastic waste, and microplastics (MPs) are the most common type of waste. They can be found in household products, such as sea salts. Therefore, monitoring pollution levels is essential to improve marine health and food safety. This study examined the MP levels in salts produced from the North Atlantic and North Seas and analyzed the
The consequences of climate change and increasing disasters jeopardise the livelihoods and resilience of some of the world’s most vulnerable countries. Strengthened international efforts to mobilise and allocate additional climate and disaster resilience financing are required to address the needs of the countries that have least contributed to climate change and who currently are at the forefront
Today, 86% of children between the age of 1 and 5 are enrolled in preschools in Sweden. The outdoor environment is important to support children’s development, health, and wellbeing. Children’s perception of what an appropriate outdoor environment is often differs from what adults consider to be a god and healthy outdoor environment. The aim of this study is to confirm the gap in supervision
The demand for biofuels is increasing as a result of increased climate mitigation ambitions aiming to replace the use of fossil fuels. To meet the increasing demand, energy crops grown on agricultural land used to produce biofuels is getting more and more attention. Since agricultural land is a scarce resource, conflicts can arise between food production and biomass for biofuels, making it essenti
The spread of artificial light on Earth increases annually. One of many causes of this spread is due to increased street lighting and artificial light at night (ALAN). Lighting is one of the many necessities for people to feel safe. On the other hand, ALAN, which contributes to light pollution, negatively affects biological functions and thus biodiversity. The purpose of this study was to investig
Recycling has become increasingly relevant to solve environmental problems related to the enormous amount of plastic waste. Recycling plastic has many environmental benefits, but it is challenging to find applications where recycled plastic can provide the same functionality as virgin plastic. This thesis highlights the challenges of using recycled High-density polyethylene (HDPE) in pipe applicat
This study was done to get an understanding of how tillage effects biodiversity in agriculture soil. Therefore, this study focused on the soil organisms and various physical and chemical processes that can affect them. Soil organisms are crucial to agricultural landscapes as they perform biological processes that improve soil structure, nutrient cycling and decomposition. To ensure food produc
This study examines the perception and acceptance of the Swedish tax paid school meals, its sustainability aspects and what factors that affect the students in their food choices in the municipality of Ängelholm from a student perspective. The guidelines for school meals in Sweden is for it to be healthy but in recent years also more sustainable. A common way to enact upon the sustainable factor i
Ecosystem functions and services are vital for all humankind and our existence. Nevertheless, ecosystems are deteriorating due to human activities, while the influence over and partaking of their services is unequally distributed. A multifunctional landscape has the characteristics of supplying a broad range of ecosystem services, attracting stakeholders that will build diverse relationships to th
This literature study aims to investigate prior knowledge of the effects of heavy metals on amphibians in freshwater environments. The methodological approach for the study is based on extensive searches in the database called Web of Science. These searches then gets narrowed down with the help of with strategic search words for the subject at spotlight. The final combination of searched words, to
Ecosystem services are a crucial part of humankind’s well-being and health. They are especially important in agriculture; without them the production of food would come to a halt. The intensification of agriculture has led to a deterioration of the soil health, which in turn has had negative consequences on the ecosystem services that agricultural ecosystems deliver. The aim of this study was to r
The ongoing energy transition towards a fossil-free electricity production and sustainable future is essential to mitigate climate change and a matter of global concern. However, there are still knowledge gaps that presents challenges to the transition, one of which is opposing land-use interest and geographical placement of new electricity infrastructure. This study was conducted in collaboration
The EU procured for roughly 202000 MEUR (14% of the EU GDP) during 2021 in the public sector. The majority of these contracts are traditional, linear business model purchases. The EU has been developing several strategies, guidelines, and policies for sustainable purchasing, with Circular Public Procurement for a Circular Economy (CE) being one of them, but the implementation rate is low. Electron
Forests and forest products are important, not just for timber production, the forest ecosystem plays several important roles, such as water purification, carbon sequestration for climate mitigation and recreational values. How the forests are managed varies throughout the globe, in Sweden the most used system is the clearcutting system (CF), however continuous cover forestry (CCF) is gaining popu
It is important to look more deeply into how forest owners choose to manage their forests. If Continuous Cover Forestry (CCF) can be a suitable way for some forest owners to work with nature conservation management, and if it could work as a tool in their forest production today. This is because silvicultural methods can have a significant impact on the climate and the country's economy. In th
This study examines the potential of a nutrient-based emissions trading system and focuses on its possible implementation in the Baltic Sea region to address the problem with eutrophication in the inland sea. Emissions trading has proven to be an effective method for reducing greenhouse gas emissions within the EU through the EU ETS. The study evaluates whether similar outcomes can be achieved
Metals and minerals are prerequisites for a modern and climate-neutral society. Domestic mining facilities are also an essential part of the Swedish national economy. Sweden has a unique bedrock and is one of Europe's largest producers. However, the willingness to invest in the Swedish mining industry has dropped over the last decade. The main reason for this is the complication and uncertaint
The summer of 2018 was a reality check for many when several heat waves made the temperature rise above normal in Sweden. Especially in urban areas, where heat can be stored more easily in the building materials, the temperature was extreme due to the creation of urban heat islands. Today these areas can be detected with a tool for mapping urban heat islands. The aim of this study is to examine h
The forest contributes multiple services, among others renewable materials, carbon sequestration, and recreational value. This thesis studied the effects on forestry stemming from the revised Land Use, Land Use Change, and Forestry regulation. The question is how reduced logging, which is in line with the new regulation, affects social welfare when incorporating the benefits of ecosystem services.
