    The transition to a sustainable economy is a major challenge of our time that concerns most sectors in our society. Environmental, economic and social aspects are all important dimensions of sustainability, and agriculture is one of the most essential industries for the transition. The implementation of a bio-economy, i.e. an economy based on bio-materials and products, is seen as a key strategy towards sustainability. In this thesis a bio-based method for crop coverage in was investigated. By analysing activities applying a process perspective, information about cost systems and the economics of using bio-materials in agriculture were revealed. The main purpose of this study was to conduct an economic analysis of a bio-based production method in agriculture. The aim was to investigate existing cost activities which occur when using mulch film, and then to calculate the cost outcome for the different types of mulch film. The aim also included to find differences and similarities between the different types of mulch film, regarding the cost activities outcome. Activity Based Costing, which requires both quantitative and qualitative data, was the main theoretical framework in the analysis. The study also applied the mixed methods as research method. For this study, it means collecting and analysing both quantitative and qualitative data about the activities performed in the process. Six respondents were interviewed regarding the mulch film process and the costs it generates. The analysis was made by comparing the data from the respondents and the cost calculated with ABC. The result of the mulch film process was structured as phases containing activities, which occur during the mulch film process. Purchase, storage, lay out, maintenance service, end of season and final management were identified as existing phases. Delivery material, stock-keeping, setup machine, placing, and maintenance service were identified as principal activities existing in the phases. The activity of cultivation, collection and recycling depended and varied between the different mulch film materials. The analysis was conducted from a process perspective. All indirect costs (generated from the cost activities), as well as the direct costs (direct material and labour), were compared to one another as costs per hectare. The study shows the resources with the largest influence on the total result; extra labour and fuel. In some cases, indirect material such as irrigation tubes had a significant share of the indirect costs. A further analysis was made by comparing the bio-based mulch film process with other mulch film alternatives. The analysis also contains a critical reflection of the limitations of this study and the ABC method. The process perspective provided an informative overview of the costs connected to the mulch film process. The ABC method could probably be a useful and informative tool for understanding economic consequences of implementing certain sustainable methods in agriculture

    The process of setting science-based supply chain greenhouse gas emission targets - An exploratory study of IKEA Component’s scope 3 target setting process

    Get PDF
    Background: The world is facing global warming because of excessive release of greenhouse gases. The Science Based Target Initiative encourages companies to do their fair share in limiting the temperature increase to 2 degrees above preindustrial temperatures. This is called setting science-based targets. Little research has been made on the target setting process and there are few practical examples of companies setting targets for their supply chain. Inter IKEA, including IKEA Components, need to go through this process and want to understand the best way to do it. Purpose: The purpose of this master thesis is to, in cooperation with IKEA, determine how the process of setting supply chain (scope 3) GHG emission targets should be conducted and to help IKEA Components in doing this. Method: This research has a pragmatic worldview and uses an overall qualitative approach to understand the target setting process for scope 3 emissions. The research questions are answered by a mixed research design using both a case study and mathematical modeling. Conclusion: Setting targets for supply chain emissions is often complex since data availability and possibilities to impact rely on external entities. The general process should include; scoping, creating a GHG inventory, modeling, deciding on time horizons and commitment levels, communicating the targets and tracking progress. Companies can during this process choose to have a varying amount of stakeholder input. Using a bottom-up approach including more stakeholder input seems to be more appropriate for companies with less developed green supply chain management practices. A top-down approach better suits companies with well-developed sustainability practices. Following the, in this research proposed, process and insights will make setting supply chain science-based targets somewhat easier. The need for corporate climate action will only increase and more companies will need to set targets. Hopefully this research can be a small piece of the puzzle in helping these companies and contributing to a better planet

    Strategic asset management for improved healthcare infrastructure planning in English NHS Trusts

    Get PDF
    The management of physical healthcare assets is vital for efficient delivery of healthcare services along with improving quality and productivity, amidst significant structural and funding re-organisation within the NHS. Capital allocations are under pressure and advanced strategic planning of healthcare infrastructure is required to maintain services. In doing so, the complexity of multiple interacting systems and mixed stakeholder expectations and competencies need to be addressed. The relationship between stakeholder public consultation and estates strategy development in theory and practice is poorly understood and further theoretical development is required to advance our knowledge in Strategic Asset Management (SAM). This thesis adopts an interpretivist paradigm, and an abductive approach with a case study design methodology. Data were collected from six case studies comprising 91 participants (focus groups and workshops); 6 unstructured interviews; 907 questionnaires; and observations resulting in over 30 hours of transcribed data, along with web-based document analyse (desk studies) within 149 NHS Trusts. The data were further analysed using thematic analyses. Findings reveal how localised conditions within individual healthcare Trusts influence the ways in which national initiatives are interpreted and incorporated; these impact existing ways of developing an estates strategy and in some cases, have implications on the usability of associated healthcare infrastructure spaces. This had clear implications on existing SAM practice, which were diverse, driven by individual project team competencies and associated project management practice. In practice, more focus was given to technical competencies (knowledge of SAM datasets and tools) and behavioural competencies were downplayed. Thus, the integrative Strategic Asset Management (iSAM) framework developed in this research, established a unique baseline to develop SAM plans from a complex interaction of care, estates and transport, providing a valuable resource for healthcare planning teams. Stakeholder consultation should be selective (representative sample) and the content of consultation should be appropriate at various SAM stages. Trusts should clearly indicate how their plans have been influenced, given the feedback from stakeholder consultation. Thus, moving it from a tick box exercise, to one that adds value in the decision making process. Empirical findings revealed that although literature promoted tools and methods to facilitate SAM, in practice, these were hardly used and most teams within English healthcare Trusts were not aware of best practice tools and solutions. Structuration theory was further used as a heuristic device to theoretically triangulate the empirical findings and contribute to a nuanced understanding of SAM within healthcare Trusts. In doing so, a middle range theory for integrative SAM (iSAM) was developed. It revealed that a dynamic system of individual action and organisational structure both constrained and enabled SAM. It was evident that the process of SAM is an open, emergent process of sense making rather than a pre-determined and closed process following prescriptive rules. This thesis has advanced knowledge in SAM and has raised the importance of front end project management within English healthcare Trusts. The new integrative and interdisciplinary iSAM framework facilitates the development of estates strategy and stakeholder consultation decision-making within healthcare Trusts
