Mätning av ekosystemtjänster i jordbrukslandskapet :

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

Chachaklum, a viable initiative? : a stakeholder management approach towards a community enterprise

Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime. This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.

Att utveckla en kurs i miljösäkrade inköp

Today we see a growing need and interest in working towards sustainable development. To be able to contribute to a sustainable development as individuals/business we need to emphasize the importance of education and contextualisation that learning occurs in a sense that is relevant to the learner.This is the background to this study, which in turn is the basis for an education that focuses on how to environmentally secure your purchases, an opportunity for us to set environmental standards purchasing products and services. The process for purchase is considered by many to be a key factor in businesses work towards sustainable development. Key people in this process and target audience for this education is environmental, purchasing and procurement managers.The purpose of this study is to design an education calledMiljösäkrade inköp from the target audiences? knowledge, interests and attitudes, together with literature.

Hur tiggeri konstrueras som ett socialt problem i den massmediala debatten

The Swedish stock-market gives investors an opportunity to benefit from the global growth while financing companies invests and contributes to a socio-economic development. Parallel to the ownership of the funds also follows a responsibility as companies in the funds affect society and the environment. The growth of savings in funds, combined with an increased focus on sustainability has developed SRI (socially responsible investment). Therefore it is interesting to examine whether responsibility is an exception, which only concerns SRI-funds or a general principle, which includes the whole Swedish stock-market.The results of the survey makes it clear that all the Swedish major banks actively works to integrate sustainability within the respective bank's business to achieve a more sustainable financial system. Thus concludes the investigation that responsible investments are a general principle on the Swedish mutual stock-market.How responsibility is integrated in fund management differ between the banks.

Hållbar stadsutglesning. Om människors inköpsresor och färdmedelsval före och efter etableringen av Allum köpcentra

External shopping malls in the context of urban sprawl have, according too much of the previous research, had a negative connotation when it comes to urban planning and a sustainable society. In recent years, some of this research on the issue has changed course towards that it might be some positive opportunities and elements in this development, given that it follows certain patterns. This latter development is what we have chosen to look deeper into in our study, Sustainable urban sprawl.The shopping mall Allum in Partille center has been the subject of this case study, to explore how people's shopping habits and travels in connection with these purchases has been affected by the establishment of an external shopping mall from a sustainability perspective.The method we used was a questionnaire distributed at workplaces in Partille. The collected data were then analyzed by using some of the dominant urban planning theories, for thus underpin our analysis. We have supplemented the study with a collection of information on existing and planned shopping centers in Gothenburg region.Our study shows that external shopping centers located in already developed areas, with an existing social structure, can help to create a more compact city with fewer and shorter shopping trips, and more sustainable transport choices when purchasing goods and services..

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.

Elementkoncentrationer i gran utmed en markfuktighetsgradient :

One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.

H?LLBARA INTERMODALA TRANSPORTER I EU En studie om EU:s transportpolitiks inflytande p? samverkan mellan transportslag f?r h?llbar mobilitet

The transport sector is one of the biggest pollutants in the European Union. In relation to transport policies and environmental policies, intermodal transportation solutions are of high relevance to establish a sustainable transport sector for the future. Intermodality which is defined as smooth transition between transport modes is a key figure for how modal shares are divided between the modes of transportation. The aim of this bachelor?s thesis is to examine the research gap whether policies intended for a specific transport mode affects each other in relation to EU policies intended for intermodality.

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.

Turism under ansvar. : En kvalitativ studie om upplevelsen av att arbeta med CSR-frågor inom reseindustrin.

The focus of this essay is set on a number of processes that affect the challenges of the tourist trade, to be more precise ? an analysis of the attitudes towards tourism and sustainability within this line of business ? from an ethical and moral as well as social view. These issues are examined with reference to the concept of CSR (Corporate Social Responsibility). Thus, acquaintance with theories of social constructivism, post colonialism, globalisation and global civil society is essential in order to understand the analysed material. The essay is mainly based on the outcome of qualitative interviews with various kinds of persons working with CSR related questions.

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.

CSRD och det offentliga : En analys av svenska kommuners anammande av CSRD

The European Union's Corporate Sustainability Reporting Directive (CSRD) aims toenhance and standardize sustainability reporting to support the green transition. While the public sector is expected to lead in sustainability, the application of CSRD within Swedish municipalities is fragmented. Many municipally owned companies fall below reporting thresholds individually, creating a transparency gap despite the municipal group often exceeding these thresholds collectively. This discrepancy raises moral and strategic questions regarding public accountability and the effective utilization of the framework. This thesis investigates the rationale for the proactive adoption of CSRD principles bySwedish municipalities, irrespective of formal legal requirements.

Gestaltning av stadens utemiljöer - Naturlikt kontra formellt & abstrakt :

In the increasing urban environments and the modern societies demands for sustainability there is a challange in planning cities with a balance between density and a satisfying access of recreational environments. For attractive cities these environments need to be designed to fit every inhabitants? demands and opinions in some way. Increased knowledge and understanding is therefore needed about how different design styles in landscape architecture affect people and the cities. In this bachelor thesis benefits and disadvantages as well as the experience and impact of two fundamental design styles i discussed; naturalistic and formal/abstract design.

Avel för hållbarhet och livslängd hos köttdjur

The purpose of this literature study was to investigate the possibilities to improve longevity and stayability of beef cattle with breeding. The breeding goal for beef breeds is to produce animals with high capacity for growth and good feed efficiency. Longevity and sustainability are two important features to include in the breeding goal. If longevity is increased each cow can produce more calves and the number of female calves used for recruitment can be reduced and only the best heifers need to be selected for breeding. The benefits of longer life is that it lowers the costs of recruitment animals, it increases the number of young animals that become available for slaughter, and it increases the proportion of high producing animals in the herds.
