Every year in December to February the dust laden Harmattan blows from Sahara towards southwest to the countries along the east west going coast of the Gulf of Guinea. Only few investigations have quantified external dust deposition in forests and plantations in that region and hereby the nutrient input by dust. This paper investigates three different methods for sampling and quantifying dust depo
Things are seldom ideal. The quality in information underlying the assessment of risk and support decisions is not an exception. Quantitative measures of uncertainty are extremely useful, but a problem with quantitative measures of uncertainty is that qualitative aspects of uncertainty, e.g. related to weaknesses in background knowledge or deep uncertainty (Cox 2012), are difficult to address.
In 2014 a small fire started in a forest in central Sweden. Within a few days it developed into the largest wildfire in Sweden in the last 50 years. As the scale of the fire increased, so did the need for direction and coordination of the resources engaged in the response operation. Both official investigators and the research community have studied the challenges and come up with recommendations
Nascent US carbon markets reward farmers for reforesting agricultural land, with consequent ecological co-benefits. We use a dynamic optimization model to determine the likelihood of an orchard farmer in northern California converting to forest under 90 plausible future scenarios. We find reforestation to be a highly unlikely outcome, occurring only 4.0% of the time under current economic, biophys
Electronic waste is the fastest growing waste category, seen as a consequence of the industry’s rapid technological advancement. The waste in this industry is problematic due to the inherent heterogenic property of devices, the toxicity of the waste, as well as resource intensive production of the required materials. To decrease this waste and the resource demand in the production of electrical de
Emissions from drained organic soils is a big contributor to global warming and corresponds to 5% of global and 25% of Sweden’s greenhouse gas (GHG) emissions. This study uses a GIS-analysis to map the organic soils in Kristianstad municipality in Sweden and what land use occurs on these soils. The purpose of the study is to provide the municipality with information when investigating the possibi
Packaging waste is an active environmental problem. There is an ongoing process of change in both the EU and Sweden to reduce the amount of packaging waste and create more resources for a circular flow. Considering this, there are contexts, despite new legislation, where single-use packaging will still be offered. Therefore it becomes significant to understand how the consumer can be influenced in
Environmental pollution caused by human activity is one of today's biggest dilemmas. Pollution in air, water and soil can pose risks to human health and the environment and can lead to a reduction in available resources. Investigating and remediating contaminated areas is therefore an important task. In the past 20 years, there have been two major spills of gasoline and diesel at the Energy Po
This paper explores how barriers and risks are perceived by different actors involved in Northvolt's establishment in Skellefteå, Sweden, through the Multi-Level Perspective (MLP) and risk perspective. The study employs a qualitative research design and utilizes document analysis and semi-structured interviews to collect data. The findings contribute to the existing risk framework by introduci
This study aims to investigate the ecological sustainability of different beverage packaging and compare this to consumers’ perception of the most environmentally friendly packaging type. A literature analysis was made to understand the advantages and disadvantages of different packaging as well as consumer behavior from other surveys in other studies. Lastly this study conducted and preformed its
To meet climate objectives our society needs to be more resource efficient, and a circular economy is part of the solution. Maintaining and repairing products to prolong their lifetime is usually better than replacing the product. In Sweden there are existing economic policies such as value added tax and tax reductions that incentivize the consumer towards prolonging the life of their products, bu
Due to the growing e-commerce volumes, product returns have become an increasingly important issue within the fashion industry. About 70 % of all returns are caused by poor fit or size. Therefore, there is a need to improve fit and size information online to decrease the rate of returns. In recent years, there has been an increased interest for implementing AI solutions to improve consumer informa
The main drivers of the alarming biodiversity decline are land use and land use change, primarily due to agriculture. It is therefore important to assess the impact on biodiversity caused by production of food and to do so, life cycle assessment (LCA) is a method widely used. Since the UNEP-SETAC provisionally recommended the method by Chaudhary et al. (2015, updated 2018) for impact assessments o
The ongoing climate changes pose a serious threat to both societies and ecosystems globally. Intensification of extreme weather, floods in combination with heat waves and droughts are some of the challenges that require adaptable and sustainable solutions. Nature-based solutions (NBS) have been identified as a powerful tool for creating resilient and sustainable cities by integrating natural proce
The European union and the Convention on biological diversity require 30% of all land to be protected by 2030, stressing the necessity for increased nature conservation. To meet the requirements different forms of protection are needed. Thus, nature conservation agreements (NCA) relevant for further exploration, as they are not used in as large of an extent as other nature conservation types. Thi
Regulations regarding management of dredged sediment from the maintenance of artificial ponds and other wetlands are ambiguous. Currently in Sweden, compliance with guidelines concerning pollutants is often prioritized over the climate impact associated with the transportation during disposal of these sediments. Therefore, this study aimed to evaluate the applicability of current guidelines to dre
Air pollution is a major environmental and health problem globally, with traffic emissions being a significant source of many pollutants. The aim of this study is to investigate whether the levels of nitrogen dioxide (NO2), ground-level ozone (O3) and coarse particles (PM10) in air changed during the covid-19 pandemic in Sweden, and whether the change varied between urban and rural areas and depen
Forestry in Fennoscandia is currently dominated by conventional rotation forestry, but an increased interest in continuous cover forestry (CCF) methods has been observed in both Finland and Sweden. The Finnish state-owned enterprise Metsähallitus has since a couple of years used CCF in 25% of their forests, and this paper aims to identify factors that could hinder or prove disadvantageous for Svea
This study presents a systematic overview and mapping of potential metrics for evaluating the impact of forest management on biodiversity in Swedish forestry. The primary approach involves quantitative Life Cycle Impact Assessments (LCIA) as part of Life Cycle Assessments (LCA). Given the increasing need to integrate the impact on biodiversity into complex value chains, the absence of a standardis
