Didaktiska arter
The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. Easily recognizable indicator species could improve dialogue between the scientific community, administrative authorities and the general public. Such species could be used in education systems, associations or in information campaigns. Therefore, I have chosen to refer to these species as didactical species.
Uthållig estetik i landskapet - om att synliggöra sitt förhållningssätt till hållbarhet : Sustainable landscape aesthetics - to demonstrate ones attitude towards sustainability
Abstract
In my work, I have tried to define and clarify the conception of sustainability seen from my perspective as a landscape architect. With a basis in literature studies, I have analysed and commented on different applications, contents and meanings of sustainability and endurance. This compilation is based on how a number of writers, researchers and authorities consider the importance of integrating ecological, social and economic aspects of sustainability in city planning. My perspective has mainly been founded on the anthologies and compilations from the 80´s and 90´s where Per G. Berg and Björn Malbert acted as editors.
Koldioxidlagring - realitet eller utopi? : En komparativ fallstudie med syfte att undersöka potentialen för koldioxidlagring i geologiska formationer och biologiska sänkor och dess förmåga att bidra till hållbar utveckling
To curb greenhouse gases and mitigate climate change is one of the biggest challenges human society face today. Carbon dioxide (CO2) has accumulated rapidly in the atmosphere as a consequence of burning of fossil fuels and deforestation. The aim of this study is to explore two methods to store carbon dioxide in geological formations and biological sinks. The aim is also to discuss the two mitigation options from a sustainable perspective and whether it can lead to a better environment and benefits for local and global societies. The research questions are: Which method to store carbon dioxide, geological or biological, is the most effective? Which method to store carbon dioxide, geological or biological, has the greatest potential to promote sustainable development for local communities?The method used is a comparative case study and presents four case studies that explore the potential for CO2 storage offshore in Norway and Brazil; and in tropical forests in Mexico and Brazil.
Utvärdering av Naturvårdsverkets bedömningsgrunder för makrofyter i sjöar
According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.
Measuring Garden Footprints
REFERATUppfödarkåren inom ASVH (Avelsföreningen för svenska varmblodiga hästen) har genomgått ett generationsskifte ifrån den äldre uppfödaren med lantbruksbakgrund och en gedigen erfarenhet av avel (d.v.s. uppvuxen på landsbygden, med föräldrar med intresse och erfarenhet inom hästavel), till uppfödaren som inte har någon lantbruksbakgrund och saknar större avelserfarenhet. Det som kan skilja den äldre mer erfarna uppfödaren mot dagens uppfödare är att den nyblivne uppfödaren oftast har en stor vilja och drivkraft att utbilda sig inom avel. Generationsskiftet kan komma att påverka den svenska varmblodsaveln negativt då oerfarna uppfödare använder sig utav ej beprövat avelsmaterial, detta resulterar i att den svenska varmblodsaveln inte tar de framsteg som är önskvärda. För att få klarhet i hur uppfödarstrukturen ser ut i dagens samhälle genomfördes denna studie.Syftet med denna studie var att i likhet med Bäckbergs (1995) studie (Marknadsstudie av svensk halvblodsuppfödning 1994-1995) studera uppfödarstrukturen, stostrukturen, stoägarnas kriterier för att sätta ston i avel samt utreda hur uppfödarkåren har förändrat sig sedan dess.
Alternativa skogsbruksmetoder i Norden : ett välbehövligt komplement?
Clearcutting systems have been the dominating silvicultural approach during the last decades in the Nordic countries. While economically rational, it is also leading to a trivialisation of the flora and fauna, and may result in negative reactions of people in urban settings. As a consequence of this, and a more diversified view on which goods and services forests should deliver, there is an increasing interest in broadening the range of silvicultural methods that are used.
The term continuous cover forestry (CCF) represents a suite of methods that have gained increasing interest in the Nordic countries. In CCF a considerable amount of the trees are left after harvest to favour values that require a continuity of tree-covered areas. There are thus hopes that this method will meet the needs for maintaining biodiversity and satisfy social and cultural values.
Miljömedvetenhet, miljöansvar och miljöbeteende En kvantitativ analys av det ekologiska medborgarskapets grunder
I samhällsdebatten om hur det hållbara samhället ska uppnås framhålls idag allt oftare individens bidrag till miljöproblemen samt dennes ansvar för sina handlingar och dess konsekvenser. Hur individbeteenden bäst förändras råder det dock delvis delade meningar om, och i den debatten står Ecological Citizenship-teorin för en syn på långvariga beteendeförändringar som styrda av vår inre motivation. Man antar ett samband mellan individens medvetenhet om miljökonsekvenserna av sina handlingar och dess beteende, och att detta samband förmedlas via en positiv attityd till individens personliga miljöansvar. Det är dessa samband som studeras i denna uppsats, med hjälp av statistisk analysmetod undersöks miljömedvetenhetens direkta och indirekta effekter dels på aggregerat miljöbeteende, och dels på tre olika typer av miljöbeteenden, nämligen resurssparande beteenden, transportbeteenden samt konsumentbeteenden.Resultaten av studien visar på att en indirekt effekt av miljömedvetenhet på aggregerat miljöbeteende via attityd till ansvar mycket riktigt föreligger, en dryg tredjedel av den totala effekten av miljömedvetenhet går vägen via ansvar. För de tre undergrupperna av miljöbeteenden framträder resurssparande beteenden som mest påverkade av både miljömedvetenhet och attityd till ansvar, men det är för transportbeteenden som den indirekta effekten utgör störst andel av den totala effekten.

Ett nödvändigt begränsat agerande - En kvalitativ studie om socialsekreterares upplevelse av handlingsutrymme
Social workers in the Social Services are seen as professionals and they are associatedwith a substantial degree of freedom to carry out their work in order to interpret theSocial Services Act and make decisions. This freedom is referred to as discretion andis a central aspect of the role of the social worker. But the social worker is employedwithin an organisation that exists in an environment influenced of political decisionswhich sets boundaries to how far the freedom stretches. The general aim with thisthesis is to gain insight in how social workers within the Social Services experiencetheir discretion. Secondary this thesis also aims to explore how discretion is shapedand negotiated.
Leder storskaliga landinvesteringar i jordbruk till hållbar utveckling? En fallstudie av projektet ProSavana i Moçambique
Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.
Östra Kvillebäcken En gröna stadsdelen? En fallstudie över Östra Kvillebäcken i Göteborg
The study is a case study about the green urban district, East Kvillebäcken, located in Gothenburg, Hisingen. East Kvillebäcken is the first urban district in Sweden with ambition to build sustainable according to the certification system Miljöbyggnad, which make it a pioneer project. The purpose is to investigate the upcoming and the meaning of the green urban district in East Kvillebäcken and show how public employees think the urban district can affect social, ecologic and economic aspects in the area. Dialogue interviews were done with four public employees, one estate agent and two residents. Local plans and other authority documents were used to get a deeper understanding for the case study.
Fallstudie: en analys av Kungens Kurva utifrån Huddinge kommuns vision för vidare utveckling av området
In this thesis, a case study of Kungens Kurva in Stockholm is made. The municipality of Huddinge has designated the area, which is an external shopping-center, as one of its key development areas in the future. The municipality has established a future vision for the area, which extends until 2030. The vision claims, inter alia, that Kungens Kurva along with Skärholmen will become a vibrant suburb. How well the values and aims of the vision are met in the current area situation is discussed in the case study by a number of analysis that carries out the existing structures and characters of the area.
Trakthyggesfria skogsbrukssätt : kunskap, förutsättningar och attityder
Forestry has three main aspects to take into consideration today; economical, ecological and socio-cultural. In order to reach the broad policy goals for sustainable forest management, an increased variety of management approaches are requested. Today clear-cutting is the only method used in 96 % of the managed forests in Sweden. The Swedish National Board of Forestry has therefore initiated a project in order to investigate and develop Continuous Cover Forestry (CFF). This study is a part of this project.
