    The flip-or-flop boutique: Marine debris on the shores of St Brandon’s Rock, an isolated tropical atoll in the Indian Ocean2016In: Marine Environmental Research, ISSN 0141-1136, E-ISSN 1879-0291, Vol. 114, p. 58-64Article in journal (Refereed)
    Abstract [en]

    Isolated coral atolls are not immune from marine debris accumulation. We identified Southeast Asia, the Indian sub-continent, and the countries on the Arabian Sea as most probable source areas of 50 000 items on the shores of St. Brandon’s Rock (SBR), Indian Ocean. 79% of the debris was plastics. Flip-flops, energy drink bottles, and compact fluorescent lights (CFLs) were notable item types. The density of debris (0.74 m-1 shore length) is comparable to similar islands but less than mainland sites. Intact CFLs suggests product-facilitated long-range transport of mercury. We suspect that aggregated marine debris, scavenged by the islands from currents and gyres, could re-concentrate pollutants. SBR islets accumulated debris types in different proportions suggesting that many factors act variably on different debris types. Regular cleaning of selected islets will take care of most of the accumulated debris and may improve the ecology and tourism potential. However, arrangements and logistics require more study.

    An empirical evaluation of sustainable operations practices and performance in the Swedish manufacturing industry2015Manuscript (preprint) (Other academic)
    Abstract [en]

    This study explored whether there are patterns linking sustainability practices and performance in the Swedish manufacturing industry. Meanwhile, the relationships between sustainability improvement practices and companies’ triple bottom line performance were investigated using survey data from Swedish manufacturing companies. Treating each sustainability practice and performance indicator as an individual item, factor analysis and cluster analysis were conducted to explore the potential patterns and relationships. The results indicated that the triple bottom line provides a valid outline for representing companies’ sustainability practices in the Swedish manufacturing industry. In terms of sustainability performance, the results showed that economic performance was often treated as a separate category in practice, whereas environmental sustainability and social sustainability were often combined. Process and product technology level was positively correlated with environmental performance and innovation performance. Economic, social, and environmental practices had positive correlations with performance in the respective area. Even though not all social and environmental practices directly improved companies’ economic performance, some social and environmental practices, such as education, individual development, and environmental health improvement, had an indirect effect and, thus, are deserving of specific attention. These selected practices often had a positive impact on product and process innovation, which could further improve companies’ economic performance.

    The relationship between disclosures of corporate social performance and financial performance: Evidences from GRI reports in manufacturing industry2015In: International Journal of Production Economics, ISSN 0925-5273, E-ISSN 1873-7579, Vol. 170, p. 445-456Article in journal (Refereed)
    Abstract [en]

    Whether the corporate social performance affects the financial performance is still unclear in many manufacturing companies. We commonly expect, on one side, that profitable corporations have stronger incentives to reveal information on social performance in order to improve their publicity; on the other hand, companies may face the fear of rising costs due to Corporate Social Responsibility (CSR) activities. With increasing concerns of CSR, it is timely to investigate the relationship between the disclosure of corporate social performance and financial performance. In this paper with the above study objective, we use Global Reporting Initiative (GRI) reports of 75 sample companies, collect evidences by applying the method of structured content analysis of the cases and attempt to identify this relationship. The corporate social performance is measured by the indicators according to the GRI guidelines, i.e. within the categories of Labor practices and decent work, Human Rights, Society as well as Product responsibility. Financial performance is measured by return on equity, sales growth and cash flow/sales ratio. Using statistical evaluation methods, our results indicate that the categories of Human Rights, Society as well as Product responsibility display a significant and positive correlation with the return on equity. Same conclusion also holds for many CSR indicators. Nevertheless, when examining the CSR practices across different manufacturing sectors, we have not observed significant differences. The study results are important for understanding the development and implementation of CSR practices in the manufacturing industry.

    Does supplier involvement affect Swedish manufacturers’ sustainability?2015Manuscript (preprint) (Other academic)
    Abstract [en]

    This study examines the moderating role of supplier involvement in the focal company’s sustainable initiatives. Survey methodology was used to collect data from 349 Swedish manufacturers. Partial least squares structural equation modeling was then applied to analyze the causal relationships and moderating effects. The results showed that there was a significant positive relationship between sustainable drivers and sustainable improvement practices within the focal company itself. The focal company’s sustainable improvement practices significantly contributed to its sustainable performance. Moreover, the high levels of supplier involvement in environment-related work significantly strengthened the relationship between the focal company’s sustainable practices and performance. This study contributes to the literature in the field of green supply chain management. The results indicate not only that a “win-win” opportunity exists for members of the Swedish manufacturing industry who implement sustainable practices, but also that organizational green capabilities can be strengthened by cooperating with suppliers through organizational learning.

    The phosphorus mass balance: identifying ‘hotspots’ in the food system as a roadmap to phosphorus security2012In: Current Opinion in Biotechnology, ISSN 0958-1669, E-ISSN 1879-0429, Vol. 23, no 6, p. 839-845Article, review/survey (Refereed)
    Abstract [en]

    Phosphorus is a critical element on which all life depends. Global crop production depends on fertilisers derived from phosphate rock to maintain high crop yields. Population increase, changing dietary preferences towards more meat and dairy products, and the continuing intensification of global agriculture supporting this expansion will place increasing pressure on an uncertain, but finite supply of high-quality phosphate rock. Growing concern about phosphorus scarcity and security, coupled with the environmental impact of phosphorus pollution, has encouraged an increase in research exploring how phosphorus is used and lost in the food system-from mine to field to fork. An assessment of recent phosphorus flows analyses at different geographical scales identifies the key phosphorus 'hotspots', for example within the mining, agriculture or food processing sectors, where efficiency and reuse can be substantially improved through biotechnological approaches coupled with policy changes.

    Controls of sediment nitrogen dynamics in tropical coastal lagoons2016In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 11, no 5, article id e0155586Article in journal (Refereed)
    Abstract [en]

    Sediment denitrification rates seem to be lower in tropical environments than in temperate environments. Using the isotope pairing technique, we measured actual denitrification rates in the sediment of tropical coastal lagoons. To explain the low denitrification rates observed at all study sites (amp;lt;5 μmol N2 m-2 h-1 ), we also evaluated potential oxygen (O2 ) consumption, potential nitrification, potential denitrification, potential anammox, and estimated dissimilatory nitrate NO3 ) reduction to ammonium (NH4 + ; DNRA) in the sediment.15NO3 and 15NH4 + conversion was measured in oxic and anoxic slurries from the sediment surface. Sediment potential O2 consumption was used as a proxy for overall mineralization activity. Actual denitrification rates and different potential nitrogen (N) oxidation and reduction processes were significantly correlated with potential O2 consumption. The contribution of potential nitrification to total O2 consumption decreased from contributing 9% at sites with the lowest sediment mineralization rates to less than 0.1% at sites with the highest rates. -3 reduction switched completely from potential denitrification to estimated DNRA. Ammonium oxidation and nitrite NO2 ) reduction by potential anammox contributed up to 3% in sediments with the lowest sediment mineralization rates. The majority of these patterns could be explained by variations in the microbial environments from stable and largely oxic conditions at low sediment mineralization sites to more variable conditions and the prevalences of anaerobic microorganisms at high sediment mineralization sites. Furthermore, the presence of algal and microbial mats on the sediment had a significant effect on all studied processes. We propose a theoretical model based on low and high sediment mineralization rates to explain the growth, activity, and distribution of microorganisms carrying out denitrification and DNRA in sediments that can explain the dominance or coexistence of DNRA and denitrification processes. The results presented here show that the potential activity of anaerobic nitrate-reducing organisms is not dependent on the availability of environmental NO3. © 2016 Enrich-Prast et al.

    Kommunperspektiv på uppströmsarbete i Sverige i dag och i framtiden2018Report (Other academic)
    Abstract [en]

    Upstream work is an important measure to reduce environmental pollu­tion in society and prevent pollution that has already been introduced to society from entering the water- or nutrient cycle. Although upstream work started in the 1960’s there is still little documentation on its practice. We have investigated how the upstream work is carried out in Swedish water and wastewater organisations, and potential future directions, for wastewa­ter, raw water and stormwater. The intention was also to provide munici­palities with the opportunity to express needs and contribute with success stories from their own work. The report is to be seen as a qualitative inves­tigation rather than a broad survey of the upstream work. The project was financed by Svenskt Vatten Utveckling and Sweden Water Research. The main author is Emma Fältström, PhD-candidate at Sweden Water Research and Linköping University.

    A literature review identified tools that are used or have the potential to be used in upstream work. After, a survey was conducted with 44 water and wastewater organisations. Based on the survey, 12 organisations were selected for interviews.

    The majority of respondents had some kind of existing upstream work today. The upstream work seem to work mostly well and the majority of respondents saw upstream work as an important part of the water and wastewater sector’s responsibilities. However, several municipalities feel a need to do more and most survey respondents have less than one full-time employment dedicated to upstream work. Several municipalities also state that upstream work needs higher priority. It was, however, experienced as difficult to allocate time and money when it is not clear what the work entails, and when the measurable positive effects are not always obvious.

    How the work is practically executed in the municipalities differs. There­fore, there is no consensus about the needs for future development of upstream work. As the work largely differs, a national coordinating function could facilitate exchange of experiences between municipalities. A confer­ence or seminar focusing on upstream work could also contribute to the exchange of knowledge. Specific guidance on grease, general guidance for stormwater, as well as overarching guidance for upstream work in general was put forward as important issues by several municipalities. Amount and quality of the cooperation with e.g. the municipal environmental depart­ment and county administrative board also differ between municipalities. This issue require further attention and in-depth studies.

    The results from this study provide a first insight into how upstream work is carried out in the municipalities. Primary beneficiaries of these results are personnel at water and wastewater utilities and municipal environmental departments. Further, the report provides a first insight into what could be included in upstream work. This contribute to an increased understanding of the work, which should be interesting for water and wastewater managers as well as different municipal departments and other authorities.

    Climate Change Transformations in Nordic Agriculture?2017In: Journal of Rural Studies, ISSN 0743-0167, E-ISSN 1873-1392, ISSN 0743-0167, Vol. 51, p. 28-36Article in journal (Refereed)
    Abstract [en]

    Climate change is expected to have negative impacts but also to bring potential opportunities for agriculture and crop productivity in the Nordic countries. Little research has been conducted at the farmer level to identify what adaptation measures are being considered or already taken and transformative these are. Based on semi-structured interviews with farmers and extension officers from two of the most fertile agricultural areas of Finland and Sweden, this study examines to what extent Nordic farmers are engaged in transforming their farming systems. The results show that some transformational changes are taking place already but most changes are incremental. Currently, agricultural policies and regulations are perceived as a greater adaptation challenge than climate change.

    Remote sensing of vegetation in the Sudano-Sahelian zone: A literature review from 1975 to 20142016In: Journal of Arid Environments, ISSN 0140-1963, E-ISSN 1095-922X, Vol. 124, p. 257-269Article, review/survey (Refereed)
    Abstract [en]

    Scarcity of in situ vegetation data inhibits research and natural resource management in the Sudano- Sahelian zone (SSZ). Satellite and aerial remote sensing (RS) constitute key technologies for improving the availability of vegetation data, and consequently the preconditions for scientific analysis and monitoring. The aim of this paper was to investigate how the hands-on application of RS for vegetation analysis has developed in the SSZ by reviewing the scientific literature published between 1975 and 2014. The paper assesses the usages and the users of RS by focusing on four aspects of the material (268 peer-reviewed articles), including publication details (time of publication, scientific discipline of journals and author nationality), geographic information (location of study areas and spatial scale of research), data usage (application of RS systems and procedures for accuracy assessments), and research topic (scientific objective of the research). Three key results were obtained: i) the application of RS to analyze vegetation in the SSZ has increased consistently since 1977 and it seems to become adopted by a growing number of scientific disciplines; ii) the contribution of African authors is low, potentially signalling a need for an increased transfer of knowledge and technology from developed countries; iii) RS has pri- marily been used to analyze changes in vegetation productivity and broad vegetation types, whereas its use for studying interactions between vegetation and environmental factors has been relatively low. This calls for stronger collaborative RS research that enables the mapping of additional vegetation variables of high relevance for the environmental problems facing the SSZ. Remotely sensed vegetation data are needed at spatial scales that suits the requirements of both research and natural resource management in order to further enhance the usefulness of this technology.

    Tree Crown Mapping in Managed Woodlands (Parklands) of Semi-Arid West Africa Using WorldView-2 Imagery and Geographic Object Based Image Analysis2014In: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 14, no 12, p. 22643-22669Article in journal (Refereed)
    Abstract [en]

    Detailed information on tree cover structure is critical for research and monitoring programs targeting African woodlands, including agroforestry parklands. High spatial resolution satellite imagery represents a potentially effective alternative to field-based surveys, but requires the development of accurate methods to automate information extraction. This study presents a method for tree crown mapping based on Geographic Object Based Image Analysis (GEOBIA) that use spectral and geometric information to detect and delineate individual tree crowns and crown clusters. The method was implemented on a WorldView-2 image acquired over the parklands of Saponé, Burkina Faso, and rigorously evaluated against field reference data. The overall detection rate was 85.4% for individual tree crowns and crown clusters, with lower accuracies in areas with high tree density and dense understory vegetation. The overall delineation error (expressed as the difference between area of delineated object and crown area measured in the field) was 45.6% for individual tree crowns and 61.5% for crown clusters. Delineation accuracies were higher for medium (35–100 m2) and large (>100 m2) trees compared to small (<35 m2) trees. The results indicate potential of GEOBIA and WorldView-2 imagery for tree crown mapping in parkland landscapes and similar woodland areas.

    Integrated Solid Waste Management: A Possible Solution to Environmental and Sanitation Problems in the Ancient City of Ibadan, Oyo State, Nigeria2012Independent thesis Advanced level (degree of Master (Two Years)), 80 credits / 120 HE creditsStudent thesis
    Abstract [en]

    The quantity of solid waste generated in Nigeria has increased at an alarming rate over the decades with lack of efficient and sustainable waste management in most cities of the country. This can be attributed to incessant increase in population, expansion of urban areas, industrialization and consumption rates. This study focuses on the ancient city of Ibadan and used Ibadan North Local Government as the case study. There are many environmental and sanitation problems in Ibadan due to improper waste management by the stakeholders involved. The result and analysis of the situation reveals that there are indications that most residents are ignorant of waste handling methods irrespective of their educational and economic status coupled with poor management of waste and lack of good environmental policy. The study analyzes options for adopting Integrated Solid Waste Management (ISWM) which comprises of waste hierarchy. Activities of Oyo State Solid Waste Management Authority (OSSWMA), Ibadan North Local Government (IBNLG) and Private Refuse Contractors (PRCs) in terms of technical know-how, financial capacity and waste equipment are not adequate to meet the tasks. In order to overcome these challenges, this research work discusses if and how Integrated Solid Waste Management can be implemented.

    Stormwater Management for Climate-Resilient Cities: Experiences, Challenges and Potentials in the Planning and Implementation of the Sponge City Program in Guangzhou2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Recognizing the risk of climate induced stress such as urban flooding and drought, the central government in China introduced the ‘sponge city concept’ to make Chinese cities more climate-resilient. Considered as a new model for urban development by some, it leads Chinese cities towards a collective transition towards alternative stormwater management. However, similar to conventional approaches to stormwater management, the sponge city program faces challenges related to planning and implementation. Using qualitative interviews this thesis aims to analyse the challenges alternative stormwater management faces in Guangzhou, with a particular focus on the planning and implementation of the sponge city program. To do so the paper elaborates to which extent alternative stormwater management is applied in Guangzhou, the drivers for the introduction of the sponge city program, as well as what the perceived challenges and solution approaches are. The main goal of the sponge city program is to reduce flooding, improve the water quality and restore the eco-system. The government provides a broad framework to ensure a local, contextual adaptation of the sponge city program. However, major challenges include the different perceptions on the program and a lack of know-how for implementing alternative measures. In the case of Guangzhou a solution has been the establishment of a sponge city bureau. It is responsible for the program’s planning, implementation and monitoring, but also coordinates between the involved stakeholders and organises capacity building to address the identified misunderstandings and lack of know how.

    Higher fear of predators does not decrease outdoor range use in free-range Rowan Ranger broiler chickens2016In: Acta agriculturae Scandinavica. Section A, Animal science, ISSN 0906-4702, E-ISSN 1651-1972, Vol. 66, no 4, p. 231-238Article in journal (Refereed)
    Abstract [en]

    Organic chicken production is currently experiencing a boom in Sweden, but has only recently gained access to a commercial slow-growing broiler strain, the Rowan Ranger. While these chickens are reported to grow at rates better suited to organic production than previously available strains, anecdotal evidence suggested increased fearfulness in this strain and concerns were raised that this may deter the birds from accessing the range. We subjected Rowan Rangers and fast-growing Ross 308 raised on the same organic farm to a set of behavioural tests while also tracking activity and outdoor use. The results suggest that although Rowan Rangers indeed show longer durations of tonic immobility, an index of predator-related fear, both strains made an outdoor visit on average once every 1.5 h and typically spent around 5% of their days in the range. Overall however, our results support the transition to Rowan Rangers in organic chicken production in Sweden.

    Quantification of carbon stock and tree diversity of homegardens in a dry zone area of Moneragala district, Sri Lanka2015In: Agroforestry Systems, ISSN 0167-4366, E-ISSN 1572-9680, Vol. 89, no 3, p. 435-445Article in journal (Refereed)
    Abstract [en]

    Homegarden agroforestry systems are sug- gested to hold a large potential for climate change mitigation and adaptation. This is due to their multifunc- tional role in providing income, food and ecosystem services while decreasing pressure on natural forests and hence saving and storing carbon. In this paper, above- ground biomass carbon and tree species diversity of trees was quantified in homegardens around two villages in the dry south-eastern part of Moneragala district of Sri Lanka. A total of 45 dry zone homegardens were sampled on size, diameter at breast height, tree height and species diversity. Using allometric equations, we find a mean above-ground biomass stock of 13 mega grams of carbon per hectare (Mg C ha-1) with a large range among homegardens (1–56 Mg C ha-1, n = 45) due to a 

    variation of tree diversity and composition between individual homegardens. Mean above-ground carbon stock per unit area was higher in small homegardens (0.2 ha, 26 Mg C ha-1, n = 11) and statistically differ- ent compared to medium (0.4–0.8 ha, 9 Mg C ha-1, n=27) and large (1.0–1.2ha, 8MgCha-1, n=7) homegardens. In total, 4,278 trees were sampled and 70 tree species identified and recorded. The Shannon Wiener index were used to evaluate diversity per homegarden and ranged from 0.76 to 3.01 with a mean value of 2.05 ± 0.07 indicating a medium evenly distributed diversity of sampled tree species. The results show a vast heterogeneity in terms of carbon stock and tree diversity within the less studied dry zone homegar- dens; results that contribute to more knowledge of their expansion potential as well as climate mitigation and adaptation potential. The results are also useful for whether homegardens should be considered to be included as an activity to enhance natural forest cover within Sri Lanka’s newly commenced UN-REDD National Programme.

    Koppla ihop fosforförsörjning och andra 75 hållbarhetsutmaningar2011In: Återvinna fosfor - hur bråttom är det? / [ed] Birgitta Johansson, Formas: Forskningsrådet Formas, 2011Chapter in book (Other academic)
    Abstract [sv]

    Fosfor är nödvändigt för allt liv och för all matproduktion. Nu varnar forskare för att fosforreserverna kan ta slut fortare än vi anar. Men är läget verkligen så allvarligt som vissa forskare säger? Kan vi effektivisera fosforanvändningen? Hur kan vi återvinna fosfor och återföra den till matproduktion? Vad kan jordbruket göra - och vad kan vi göra i städerna? Ska vi gödsla med avloppsslam? Eller ska vi bränna slam och återvinna fosfor ur askan? Ska vi bygga om husens och städernas avloppssystem för källsortering? Vilka lösningar är rimliga i ett hållbart samhälle?

    Visualizing alternative phosphorus scenarios for future food security2016In: Frontiers Nutrition, E-ISSN 2296-861X, Vol. 47, no 3Article in journal (Refereed)
    Abstract [en]

    The impact of global phosphorus scarcity on food security has increasingly been the focus of scientific studies over the past decade. However, systematic analyses of alternative futures for phosphorus supply and demand throughout the food system are still rare and provide limited inclusion of key stakeholders. Addressing global phosphorus scarcity requires an integrated approach exploring potential demand reduction as well as recycling opportunities. This implies recovering phosphorus from multiple sources, such as food waste, manure, and excreta, as well as exploring novel opportunities to reduce the long-term demand for phosphorus in food production such as changing diets. Presently, there is a lack of stakeholder and scientific consensus around priority measures. To therefore enable exploration of multiple pathways and facilitate a stakeholder dialog on the technical, behavioral, and institutional changes required to meet long-term future phosphorus demand, this paper introduces an interactive web-based tool, designed for visualizing global phosphorus scenarios in real time. The interactive global phosphorus scenario tool builds on several demand and supply side measures that can be selected and manipulated interactively by the user. It provides a platform to facilitate stakeholder dialog to plan for a soft landing and identify a suite of concrete priority options, such as investing in agricultural phosphorus use efficiency, or renewable fertilizers derived from phosphorus recovered from wastewater and food waste, to determine how phosphorus demand to meet future food security could be attained on a global scale in 2040 and 2070. This paper presents four example scenarios, including (1) the potential of full recovery of human excreta, (2) the challenge of a potential increase in non-food phosphorus demand, (3) the potential of decreased animal product consumption, and (4) the potential decrease in phosphorus demand from increased efficiency and yield gains in crop and livestock systems.

    Kommunala kulturmiljöprogram: strategiska planeringsunderlag för landskapsanalys, kulturhistorisk värdering och utveckling av kulturmiljöer2005Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In 1999 the Swedish Parliament decided about 15 environmental goals aimed to be achieved in time for the next generation. For example physical social planning must be based on programs and strategies how cultural-historical values has been attended, so called programs of cultural heritage. By law the Swedish municipalities are responsible for reaching these goals by creating program of cultural heritage. But only a few of the municipalities have these programs, meaning that many municipalities need to create programs of cultural heritage in the next five years.

    The aim of this report is to present a model of analysis on programs of cultural heritage in municipalities for preservation and development of cultural environments. By testing the model on the municipalities of Osby and Tomelilla methods on how to create a new program of cultural heritage or how to complete existing documents are formulated.

    One of the conclusions is that one document, program of cultural heritage, functions as landscape analysis, model of cultural valuation and strategy of developing cultural values. One condition is that the program of cultural heritage is established in social planning in the municipality.

    Two case-studies, the Osby and Tomelilla programs of cultural heritage with text-analysis and interviews, constitutes the study. The municipalities do not use these programs in full extension, often based on ignorance. When the program isn’t established with politicians or employees it can’t be established with citizens. The study shows great differences between the program in Tomelilla which can be applied to the physical social planning, and the program in Osby which can’t. The conclusion is that the program needs to be adjusted for the cause if the program can’t be applied in the hysical social planning in the municipality.

    The common meaning in the municipalities is that cultural heritage is a positive factor, which makes it possible to reach the environmental goals, regional development, tourism et cetera. One important part in a program of cultural heritage is to erase the boundaries between nature, recreation and culture by finding the starting point in the specific environment, not based on the administrative responsibility.

    Trading Forests: Quantifying the Contribution of Global Commodity Markets to Emissions from Tropical Deforestation2014Report (Other academic)
    Abstract [en]

    This paper aims to improve our understanding of how and where global supply-chains linkconsumers of agricultural and forest commodities across the world to forest destruction in tropicalcountries. A better understanding of these linkages can help inform and support the design ofdemand-side interventions to reduce tropical deforestation. To that end, we map the link betweendeforestation for four commodities (beef, soybeans, palm oil, and wood products) in eight casecountries (Argentina, Bolivia, Brazil, Paraguay, Democratic Republic of the Congo, Indonesia,Malaysia, and Papua New Guinea) to consumption, through international trade. Although few,the studied countries comprise a large share of the internationally traded volumes of the analyzedcommodities: 83% of beef and 99% of soybean exports from Latin America, 97% of global palmoil exports, and roughly half of (official) tropical wood products trade. The analysis covers theperiod 2000-2009. We find that roughly a third of tropical deforestation and associated carbonemissions (3.9 Mha and 1.7 GtCO2) in 2009 can be attributed to our four case commodities in oureight case countries. On average a third of analyzed deforestation was embodied in agriculturalexports, mainly to the EU and China. However, in all countries but Bolivia and Brazil, exportmarkets are dominant drivers of forest clearing for our case commodities. If one excludes Brazilianbeef on average 57% of deforestation attributed to our case commodities was embodied in exports.The share of emissions that was embodied in exported commodities increased between 2000 and2009 for every country in our study except Bolivia and Malaysia.

    Elevers geografiska omvärldsbilder: en studie av hur elever i år 6 uppfattar det geografiska rummet.2003Independent thesis Advanced level (degree of Magister)Student thesis
    Abstract [sv]

    Denna studie är en undersökning av hur elever i år 6 uppfattade det geografiska rummet, vilka omvärldsbilder elever i skolan innehade, hur de påverkades av olika intryck från omgivningen samt om elevernas omvärldsbilder förändrades under en termin. Att inneha en omvärldsbild innebär att ha en föreställning om hur den rumsliga världen ser ut och förhåller sig. Undersökningen var av empirisk art och bestod av en namngeografisk undersökning av geografiska objket i Sverige, elevernas ritade bilder av världen, intervjufrågor samt en kartförståelseuppgift. Studien genomfördes vid två olika tillfällen för att se på eventuella förändringar i elevernas omvärldsbilder. Studien visade på att elevernas omvärldsbilder påverkades, utvecklades och innehöll all den information individen mötte och hade med sig sedan tidigare om den rumsliga världen. Undersökningen visade även på att omvärldsbilder kan förändras och utvecklas unnder en termin.

    "Månen är på semester"- En undersökning om barns föreställningar om jorden, månen och solen2003Independent thesis Advanced level (degree of Magister)Student thesis
    Abstract [en]

    The main purpose with this study was to explore students conceptions about the relations between the earth, the sun and the moon. The fields that have been investigated are size, distance and movement. This study has also investigated how students interpret the origin of the phases of the moon. Attempts have been made to find out where the students conceptions originate from. The study is based on 20 interviews with students where their own pictures about the investigated phenomena are the base. By doing a qualitative phenomenographical analysis of these interviews I’ve done categories of the students conceptions.

    The result shows that students conceptions often differs from the accepted scientific and that their conceptions are a result of pictures and models from TV and books, where the relations between the objects never are the real. Even if the students have had education they still keep on to their own conceptions. It also shows that there are a distinct connection between the students interest and their result.
