    Tourism as a tool for communicating complex environmental issues: Applying the ecosystem services framework to nature-based tourism activities across Iceland2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Throughout the twenty-first century, the lowering cost and increased availability of travel options has resulted in virtually uninterrupted economic growth of the international tourism sector. While financially beneficial, the increased movement of people has also been shown to have a negative impact on the environment, leading to the growth of a more environmentally-friendly approach to travel called nature-based tourism. One country at the forefront of the nature-based tourism movement is Iceland, and while the sector has grown significantly in the country over the past decade, the way in which information concerning environmental issues is communicated to tourists has not been widely researched. Being the case, the aim of this study was to examine the extent to which environmental issues are communicated to the general public through the use of the ecosystem services framework. Four popular nature-based tourism activities were selected for analysis; a whale watching tour, a horse riding tour, a boat tour of a glacial lagoon and a spa experience in a geothermal hot spring. A literature review concerning how the ecosystem services framework related to each of these tours was carried out and findings were compared to observatory data gathered through participation in said tourism activities. Results showed that while scientific publications could be found for each tour/ecosystem service combination, information concerning environmental issues was not widely communicated to participants in the nature-based tourism activities using the ecosystem services framework.

    Vi-skogens kommunikation om sin verksamhet till intressenter: - Retoriskanalys av bild och text2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    ABSTRACT

    Vi-Agroforestry communication has been studied to see how they use communication as a tool to attract donors. The aim is to be able to contribute to shed some light on the importance of image and text as a unified communication. Its about acknowledge what the sender (aid organization) sends out to tell potential donors. It examines how the organization communicates the problems they want to solve, which method they want to solve it with and why their organization should be the preferred option before the interest is gone by the recipient. By examine the reliability (ethos), the emotional connection (pathos) and the factual conviction (logos) of the Vi Agroforestry communication it helps to understand the organizations way of communicate with their listeners.

    The study examined Vi-Agroforestry communication through image and text. The author hopes to contribute to explore what an aid organization, like Vi-Agroforestry, choose to focus on regarding when they get to talk about their organization and their work. The organization has been analyzed based on the rhetorical basics to go on to see which framework they create their communications.

    Miljön som handelsvara: en diskursanalys över utsläppsrättssystem2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Växthusgasnivåerna i atmosfären har nått nivåer som påverkar klimatet på jorden. Det här ställer krav på politiska överenskommelser som effektivt kan verka för en minskning av växthusgaser i atmosfären. Kyotoprotokollet implementerades 1997 och innehåller lagbindande krav på medlemsländerna att minska sina växthusgasutsläpp och presenterar utsläppsrätter som styrmedel för att nå målen. Utsläppsrätter innebär att politiker sätter ett pris på rätten att släppa ut och låter verksamheter som förorenar handla med rätterna, vilket enligt nationalekonomisk marknadsteori är det mest effektiva sättet att gå tillväga. Detta kan däremot kritiseras av ekologiska ekonomer som motsätter sig prissättande av miljön.

    Diskursteori används för att studera vad som har normaliserats med införandet av utsläppsrättssystem och därför inte ifrågasätts. Analysen visade att två diskurser primärt råder i den utvalda empirin; ekonomisk liberalism och teknologisk tilltro. Fokus på vinst, tillväxt, kostnadseffektivitet samt teknikoptimism återkom i alla tre dokumenten och framställs som avgörande för att nå målen för utsläppsreduktion.

    Utsläppsrätter är ett ekonomiskt styrmedel vars styrka ligger i marknadsmekanismer, men ur ett hållbarhetsperspektiv finns problematik med prissättande av miljön; framförallt att det vilar på svag hållbarhet. Även marknadens otillräckliga förmåga att ta hänsyn till moraliska angelägenheter, prissättning av miljön och att ansvarsförskjutning mot företag placerar en större klyfta mellan människa och miljö kan tolkas som problematiskt.

    Jordbruksfåglarnas minskning i Stockholms län: En kvantitativ studie av fåglarna i jordbrukslandskapet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the 1970s, a breeding bird survey was conducted to see how many birds are breeding in Sweden. This was done because the research at the time pointed out that there was a decrease in the number of bird species. This inventory became known as atlas inventory 1, and an additional inventory was done in the 2000s, which was called atlas inventory 2. The second inventory was carried out in order to see trends in bird population distribution and to be compared with atlas inventory 1. The purpose of this study was to examine if it is possible to compare the inventories with each other to see if there are any changes in the number of breeding birds in Sweden. The study was limited to the Stockholm report area, which includes all municipalities in Stockholm County except for Norrtälje. A limitation was also made to only examine agricultural birds, where six species were selected. The results show that the number of atlas squares with data for breeding birds within the Stockholm report area have decreased between atlas inventory 1 and atlas inventory 2. To obtain these results, information was retrieved from the website Artportalen, and was then compiled and processed in Excel and ArcMap. A comparison between the period 2013-2016 and atlas inventory 2 was also done, which showed a decrease in the number of atlas squares with available data, as well as a reduction in the number of observations of breeding birds.

    The Green Wave: How communication, advocacy andparticipation measures are included indocuments important for increase bicycling inStockholm City and Nacka Municipality2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world is becoming increasingly urban. This puts pressure on a number of functions within cities, not the least the transportation system. Motorized traffic is responsible for a number of negative environmental effects, such as carbon dioxide emissions and particle pollution. To halt this development an increased share of bicyclists is needed. Stockholm County is an area with rapid urbanization. Therefore, a comparative study was undertaken to analyse how Stockholm City and Nacka Municipality are including communication, advocacy and participation measures in documents important for increased bicycling. This as those measures are important to increase the number of bicyclists. The analysis was undertaken by using two typologies, a modified version of the Transtheoretical Model of Change (TTM) to understand how the two cases include communication and advocacy measures whereas Arnstein’s Ladder of Citizens Participation was chosen to understand how participation is included in the documents. The findings suggest many similarities between the two cases but Nacka Municipality perform better with their use of social media, and the activities ”bicycle-friendly workplace” and ”winter bicycling”. From the findings three recommendations where provided: create bicycle councils to improve inclusion of bicyclists in the processes. Second, it is important to have different type of role models across the municipality, both in socio-economic strong and weak areas. And third, create dedicated outlets for bicycle issues, tentatively on a social media outlet. This will increase the status of bicycles, it will promote bicycling as a good transportation choice and it open ups channels for citizens interaction.

    Biofuel Production: Examining the development of sub-Saharan Africa through the concepts of land grabbing, environmental justice and different views on development theories2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper examines and problematize the effects of biofuel production by focusing on local communities in sub-Saharan Africa (SSA). The premise lays in a critique of neoliberal thoughts of development and the concept of sustainable development. The establishment of biofuel production in SSA has been depicted to carry with it opportunities of development for the rural population. However, there have been a big interest from foreign actors looking to invest in sub-Saharan biofuel production which have raced concern for land grabbing. A conflict of interest has emerged between Southern and Northern interests. A literature study is used as the method to examine reported outcomes on local communities in the proximity of biofuel production in order to determine if sub-Saharan biofuel production is established for the development need of SSA or the interest of the North. To analyze the results a theoretical framework has been constructed from concepts of large-scale land acquisition (land grabbing), environmental justice and the four worldviews market liberalism, institutionalism, bioenvironmentalism and social greens. The paper concludes that the large-scale production of biofuels is highly problematic due to the risk of land grabbing and Northern mitigation schemes are based on Southern lands raises the question of environmental justice. Depending on which worldview one adopts there can be several explanations to why this occur.

    Drivkrafter och hinder ur ett multifunktionellt perspektiv: Förutsättningar och utvecklingsområden för produktion av biobränsle från våtmarker2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Sweden have already reached several of their goals for energy consumption, but the overall goal to become a fossil free society can still be seen as a driving force to keep developing renewable fuels. There is financial support for wetland construction, reduce impact on the climate, improve the natural environment, for developing new techniques and for biomass fuel plants. Still, cultivation of wetland crops for energy extraction are not yet well established on the energy market. After interviews with actors interested and knowledgeable in this field, this study presents driving forces and barriers affecting the development of this energy source. Driving forces comes from the ambition to move away from fossil fuels, decrease emissions of nutrients, make room for biodiversity, and provide services for the society while helping to reach climate and environmental goals. The barriers affecting this development is that special machines might be needed for handling of the crops and also to harvest the sensitive wetlands while large areas would be needed to increase profitability. The financial support available is not enough to cover the costs for production. Also, the prices on electricity and fossil fuels are low, which lowers the profitability for this type of energy source. Bioenergy producers have not yet found an effective way to extract energy from the crops. All of this makes the demand for energy crops from wetlands small. Despite this, wetlands provide several important ecosystem services and it is therefore recommended to use the management philosophy of multiple-use. With a multifunctional view of wetlands, the value of its ecosystem services can be added to the calculations of energy production and increase its role in reaching several national climate and environmental goals.

    100 år av miljöförändringar som de registrerats i Hallsfjärden, västra Östersjön: En biostratigrafisk studie om vad bevarade kiselalger i sediment kan berätta om tidigare miljöförhållande i Hallsfjärden.2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Diatoms are microscopic, photosynthetic, single-celled organisms that are useful in studies of water qualities (eg pH, nutrients, salinity). By analyzing changes in the species composition of diatoms back in time, gives an opportunity to interpret the marine environment affected by various factors (Andren et al, 1999). The aim of the study was to study changes in diatom abundance and composition in Hallsfjärden, a bay in the Baltic Sea located north of Himmerfjärden in Södertälje. The site was chosen because it is a bay that is assumed to have a large environmental impact due to external factors such as increased population growth, water treatment plants, industrial areas, dredging and a link to Lake Mälaren. The purpose of the study therefore to investigate whether there was an environmental impact in Hallsfjärden, in order to draw conclusions about what happened in the area and what has affected the water the last 100 years.

         The survey is conducted by sampling sediment cores, studied by biostratigraphy of fossil diatoms to reconstruct past environmental conditions. The results of the analysis showed that oxygen deficiency was a particular problem, which is related to the eutrophication that are threatening some diatoms and thereby changes the species composition of ecosystems in Hallsfjärden. A plausible interpretation of the analyze results is that Hallsfjärden was adversely affected by the Södertalje area's population growth and Himmerfjärdsverkets startup by high emissions of nutrients. It has on the other hand appeared a positive impact for Himmerfjärdsverkets gradually improved purification with clearer water conditions. Hallsfjärden have proved to be a particularly sensitive ecosystem in this study, with low salinity and strong thermocline, which means that it is more affected by eutrophication and pollution in its drainage area. This causes a problem of eutrophication in Hallsfjärden due to the bay showing the influence of the surrounding areas and its emissions, which later exports further to the Baltic Sea via Himmerfjärden with the southbound flow.

    Dånvikens algblomning och dess sociala konsekvenser för fastighetsägare i Sjöudden/Gråstena i Salems kommun2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The recreational loss due to algal blooms is large even though recreation is important for human health and social cohesion. This study examines the social consequences of the autumn bloom in the lake Dånviken, Sweden, for property owners in close proximity to the lake and how future algal blooms can be prevented. Through sewerage analysis, survey, interview and conflict analysis, one can see that recreational opportunities have been threatened by the bloom through consequences such as bad odors and ruined beaches. Reduced recreation reduces social cohesion among residents as the bloom affected the social hotspots with connection to Dånviken negatively. With the help of conflict theory, we see the existence of different values ​​and uneven distribution of the power property owners have regarding the impact on Dånviken, which means increased risk of conflict in conjunction with algal blooms. The sewage situation looks better today compared to 2006 but still contributes to eutrophication through nutritional emissions. Since 2006, 54.5 % of the properties concerned have fixed their sewerage and the proportion of real estate’s connected to a sewer system has increased by 19.6 %, where the number of mini-treatment plant and soil- and infiltration beds has more than doubled. In order to prevent future blooms in Dånviken, the municipality must continue to demand better sewage and supervision, the water and sewage network also needs to be expanded among other measures. Continued studies in the area are important in order to better understand the social consequences of threatened recreational opportunities due to algal blooms.

    Hand Hygiene Barriers faced byHealth Care Workers in The Gambia:: A Health Belief Model Approach2016Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Health care associated infections cause major challenges to the provision of health care. This isdue to the burden placed on individuals, their families, and health services. Hand hygiene actions are cost effective measures towards reducing the spread of health care associated infections and have proven very effective in preventing microbial transmission during patient care. It has beenproven that health care workers hands are the main routes of transmission of health care associated infections. Despite this, hand hygiene is still frequently overlooked by health careworkers especially in settings with limited resources. This paper therefore explores hand hygieneknowledge and behaviours of public and private health care workers in The Gambia with focuson the health belief model. The required information has been gathered from 4 public and 2 private health care facilities through the use of a questionnaire based on the WHO evaluation toolkit. Hand hygiene knowledge of health care workers corresponded with their hand hygiene behaviour. Inadequate hand hygiene performance was noted in many health care workers as wellas limited availability of hand hygiene resources from health care facilities. Private health care facilities provided better hand hygiene opportunities for their health care workers yet neither private nor public health care facilities offered adequate hand hygiene training and feedback on hand hygiene performances to their health care workers.

    Kan musselextrakt (Mytilus edulis) inducera födosök hos omnivoren ruda, Carassius carassius (Linnaeus, 1758)?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Over the last three decades there has been a significant increase in aquaculture production and the demand for farmed fish is predicted to rise further. More fish are being caught to become fishmeal in aquaculture, than for direct human consumption use, while a large number of fish stocks are being depleted. Many popular farmed species are carnivores and thus brought up on a diet consisting of fishmeal and fish oil. However, several studies have shown that several fish species can be brought up on a diet consisting of mussel meal instead of fishmeal. If so, this finding can possibly lead to a more sustainable fishing in the future by reducing the number of wild-caught fish. The purpose of this study has been to examine if mussel meal extract can induce foraging in the omnivorous species crucian carp (Carassius carassius), a commercial fish that is mainly farmed in China. Induced foraging can indicate that crucian carp could become accustomed to mussels, even though mussels are not part of its natural food source. The results revealed that foraging was induced in the crucian carp by conventional feed for carp, the control diet, but not by extract of mussels.

    Conflicting interests in natural resource management: - A case study on mining in northern Sweden2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sweden is the leading mining country in Europe and the Swedish government intends to retain this position by fostering innovation, investments and cooperation. However, mining is an extractive industry with massive consequences on the surrounding environment and the people living there. In resource abundant northern Sweden mineral extraction is a contested subject, not least in respect to the traditional land use by the Sami population. This study intends to increase the understanding of the current mining trial process in Sweden, the effects on sustainable regional development and the implications for local communities. To do so, this study aims to identify which aspects that are brought forward during the trial for exploitation concession and how different interests are evaluated. For the purpose of this study, the bureaucratic mining trial process is examined and 15 mining cases studied in detail considering the exploitation concession phase. The material indicates that conflicts over the bureaucratic process is based both in what aspects that should be included in the assessment, how these aspects are evaluated and at what stage in the formal process various aspects should be brought up. Guided by the concepts of extractivism and subnational resource curse, the main finding identified is that the mining trial process is state-centred. This is displayed in the limited influence of local actors on the decision and in the use of national interest as a policy tool to evaluate conflicting land use claims. These characteristics can in turn increase the risk of a subnational resource curse in northern Sweden.

    Förekomst av växtarter i en fragmenterad skogsmiljö utifrån en öbiogeografisk teori2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study address the problem of fragmentation, and its impact on species distribution and abundance. The main aim of the study was to test the theory of island biogeography using plant species prevalence from field islets at different distances from nearest “mainland”. We have studied 40 pairs of field islets (islands) and forest edges (mainland) in agricultural landscapes in the Stockholm County. The result of the inventory was analyzed using univariate linear models-, and multivariate ordination. Our result show that the theory of island biogeography partly can explain species prevalence patterns, but not all of them. Furthermore, we found that species distributions were limited by the size of the field islets. Distance from mainland had an effect on the species composition in the field islets. Our results indicate a need to include the size of habitat fragments, and the degree of isolation as important factors determining the ability for future species dispersal to newly established habitats.

    The detrimental effect of alcohol on HIV treatment adherence: A systematic review and meta-analysis2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: The fight against HIV is addressed in both the Sustainable Development Goals and in the 90-90-90-goals set by the United Nations.Emerging evidence is suggesting a “neglected interface” between alcohol consumption and HIV. Earlier studies has sought out to quantify this relationship, but there are still uncertainties regarding the generalizability of the results and if this also applies to different types of drinking intensities.

    Methods: This study applied a systematic search for articles published between 1990-2017 in Pubmed/Medline. 46 studies was included in the final analysis.

    Results: Alcohol was found to have a significant detrimental effect on treatment adherence on all drinking intensities. All but one analysis showed a significant amount of heterogeneity.

    Conclusion: The findings of this study goes in line with previous research but adds insight on the harm of moderate drinking. The result of this and earlier findings give a clear point of direction of alcohol consumption guidelines in people living with HIV. If global targets of viral suppression should be achieved, a more holistic approach where the prevention of non-communicable diseases and infectious diseases go hand in hand might actually be the only way forward.

    Miljöcertifiering inom frisörbranschen: Grön Salongs miljöcertifiering2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    I dagens samhälle exponeras vi dagligen för flera skadliga kemikalier. Frisörbranschen är en bransch där ett flertal skadliga ämnen används som exempelvis parafenylendiaminedia och resorcinol. Enligt svensk lag är användningen av skadliga ämnena inom frisörbranschen oreglerad. Detta på grund av att frisörsalonger inte är anmälningspliktiga verksamheter. En miljöcertifiering används av kunder som en försäkran om att en certifierad salong är ett miljövänligare alternativ. I denna uppsats undersöks frisörernas perspektiv på miljöcertifieringen Grön Salong och vad som påverkar certifieringens utbredning. Resultatet har nåtts genom en enkätundersökning och semi-strukturerade intervjuer med frisörsalonger med anknytning till Grön Salong. En intervju med en styrelsemedlem från Grön Salong har genomförts för att spegla organisationens perspektiv. Resultatet visar att Grön Salong har många brister som gör att frisörsalonger väljer att avstå från att fortsätta vara certifierade efter några år. Den brist som frisörerna mest lyfter fram är den dåliga kommunikationen. Organisationens kommunikation upplevs som dålig, både offentligt på hemsidan och enskilt mellan organisation och frisör.
