Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.
Bok- och grankonkurrens i Sydsverige - markegenskaper och naturlig föryngring :
In southern Sweden, beech (Fagus silvatica) and spruce (Picea abies) are two species with similar demands on soil properties. With increased global warming and high acid deposition the future may bring larger areas were the two species are overlapping, competing for the same soil. The aim of this study was to compare spruce and beech concerning distribution, cultivation and soil properties. From available data comparisons were made between spruce and beech forests in Sweden. Soil analyses were made on samples from beech forest in southern Sweden, with and without natural regeneration of spruce.
Aktiebolag utan revisor : ett bolag utan extern finansiering?
This work is a study of subject teachers in social studies and science understand the concept of sustainable development. The work uses a qualitative and a quantitative approach. Teachers in various schools and stages have been answering questions about how they perceive sustainability, how they implement it in teaching and if they feel that school is important for the future of sustainable development at large.The theoretical background is based on environmental ethics as well as the different meanings and definitions of the concept of sustainable development. These theories and definitions are coupled with the empirical results.The study concludes that all teachers throughout the study perceive the concept of sustainable development as something ecological, something that has to do with nature. A few teachers also state economic and social dimensions.Questions about how the teachers in the study implement the concept in their teaching can be seen as three different approaches.
Den "fria" rörligheten - en uppsats om svårigheterna kring att uppnå socialt hållbar mobilitet
The thesis Den ?fria? rörligheten aims to give deeper knowledge to the notion of social sustainable mobility. My previous knowledge within the subject is focused around mobility being biased and therefore gaining particular groups of actors within society and leaving others worse off. Therefore I chose to do a critical analysis of social sustainable mobility and more precisely show which problems that exist and why.To start with, I have created a framework for social sustainable mobility, from which I have looked at the empirical material. The general empirical material is mostly based on mobility in Sweden also a more specific study is made of the Öresundregion.
Ta på era "hållbar utvecklingsglasögon"! : Ett idéhäfte som kan hjälpa pedagoger att arbeta mer med hållbar utveckling i förskolan
Natural and environmental issues are everyday parts in preschool but when educators shall consciously work with sustainable development they tend to stop at recycling and what is necessary to be done for achieving the Grön Flagg-certification. I have been observing various preschools and noticed that sustainable development is flawed, often because of the teachers lack of interest, knowledge and in some cases both. Out of this grew an idea of making a project that could help the teachers see how the work with the subject in a fun and educational way can become a part of the preschools everyday routine. I made a tutorial booklet with basic facts and activities relating to sustainable development and the three questions in my report were how much knowledge and interest the teachers initially have, if the tutorial booklet could help the teachers to produce new knowledge and interest for the topic and if it turned out to be easier for them to provide educational activities within the subject. There were three departments that participated in my survey and the methodology of collecting data was an anonymous survey with the teachers' own comments in response.
Regeringens miljösatsningar och deras förhållande till en hållbar livsstil hos det svenska folket : En studie av biståndssatsningars påverkan på hållbar livsstil i givarlandet
Swedish government aid is divided into three main themes: democracy and human rights, the environment and climate, and gender equality and women's role in development. These three themes in aid are considered by the government to be vital in order to fight poverty and create fair and sustainable development. This study will examine two of the four focus areas designated under the theme of "environment and climate". The study observes the relationship between projects in energy and water and how it promotes a sustainable lifestyle. A survey on environmental habits will be conducted.
Centraliserad decentralisering? En studie av Marrakechprocessen och dess relation till global governance
The current debate regarding organizational strategies for sustainabledevelopment is influenced by the theory of global governance. Decentralizedstructures of the global society are taken to use in the realization of a sustainabledevelopment. New roles of transnational networks and partnerships raisesquestions of the ability of global governance to co-ordinate and implement longtermsolutions without assistance from centralized and hierarchic structures basedon government. The aim for this thesis is to illustrate the current conditions forwell-functioning networks of sustainable development and examine therelationship between global governance and government. Issues of participation,decision making and compliance are examined by a case study of the Marrakechprocess, a global process to support the implementation of sustainableconsumption and production.
Droppar i havet : Mönsterdesignens relation till design för hållbar utveckling
Ett mönster är uppbyggt av ett motiv som upprepas. Denna upprepning kan fortsätta i all oändlighet. Hållbar antyder långsiktighet. Mönstrets övergripande egenskap är oändlighet. Hur kan denna egenskap hos mönstret nyttjas inom mönsterdesign för att främja hållbar utveckling? Det här kandidatarbetet undersöker mönsterdesignens möjlighet att verka för hållbar utveckling genom att se till begreppet mönster ur ett bredare perspektiv, samt i relation till design för hållbar utveckling.
Från miljöbistånd till hållbart bistånd : - En historisk studie
AbstractWith this c-composition, I am trying to give a view over what has happened in the political area and the issues that concerns environmental aid. My analyze starts in the 60-ies when the environmental debate took of. It continues trough the 70-ies, 80-ies and ends in 1994 with the report that considers the UN-conference in Rio de Janeiro 1992, ?Sustainable Aid? and what the results of the more and more important issue ?sustainable development? has offered the Swedish government ant there work with environmental aid.The question issue is: At what time in history, did the Swedisch government start to addrsess environmental aid? How did the environmental aid come to be addressed and developed in the political area from the Brundtlandreport ?Our common future? from 1987 to the UN-conference in Rio de Janeiro 1992?The result is that the environment is getting more and more important in the political arena as the knowledge about the escalating crises with the environmental problems are being taken more seriously. The problems with the environment has to be considered together with the rest of the aid- and developing questions like economy and the struggle to reduce poverty in the world.

Plantering av gran (Picea abies) på kalhyggen och självföryngring under högskärmar av björk (Betula pendula och Betula pubescens) : föryngringsresultat 7-10 år efter avverkning
The aims of the silvicultural method natural regeneration of spruce (Picea abies L. Karst) in birch (Betula pendula and pubescens) shelterwoods are to establish a new stand of tree seedl-ings and to protect those from high groundwater levels, frost damages and grass competition during its first life years.
The aim of this work has been to (i) describe how shelterwood and stand characteristics influ-ence the results from using natural regeneration of spruce protected by a shelterwood of birch, and to (ii) compare those regeneration results with planting of spruce after soil scarification in clear-cut areas.
Totally 17 harvesting sites have been inventoried and 15 of those included natural regenera-tion in birch shelterwoods, and two were subjects to soil scarification and planting of spruce. The sites represented 7-10 year old final cuts and are located in the coastal (eastern) region of the province of Norrbotten in Sweden. In all areas shelterwood and stand characteristics, as well as the number of main crop seedlings and the height of the highest main crop spruce seedling, were estimated and registered in all areas.
Föryngring och produktion av skog på torvmark
Kunskapen kring svensk torvmarksbeskogning är undermålig. En kunskapslucka som till stor del beror på att torvmark tidigare bedömts som ointressant mark i samband med skogsproduktion. Detta beror mycket på det svenska regelverkets restriktioner mot markavvattning och gödsling samt miljöaspekterna som berörs och den aktivare skötsel som krävs. Det ökade behovet av skogsråvara gör att skogsbruket söker nya marker där torvmarken har potential att etableras för skogsproduktion.Studien är en kunskapssammanställning som lyfter fram kunskap kring skogsbruk på svensk torvmark med fokus på föryngringsprocessen. Finland använder torvmarker i skogsbruket på ett sofistikerat sätt.

Fr?n rapportering till transformering: H?llbarhetskonsulters perspektiv p? CSRD:s potential till h?llbar verksamhetsomst?llning
Humanity faces a major challenge with the climate and environmental crisis, largely driven by
reckless recourse use and greenhouse gas emissions by corporations. The EU?s Corporate
Sustainability Reporting Directive (CSRD) aims to standardise corporate sustainability
reporting, making practices more transparent and comparable. This directive seeks to enhance
sustainability practices and guide market forces towards sustainability, supporting the EU?s
goal of net-zero emissions by 2050.
