    Study PopulationThe target population of the study were women aged 18 years to 69 years from households in Mwea East sub County that have experienced climate change events. As shown in table 3.1 below, the total population of female in Mwea East sub County in this age category was estimated at 38,734 (Kenya National Bureau of Statistics (KNBS)Volume III, table 2.5, (2019).Sample SizeA sample size of 449 respondents was determined as adequate for statistical analysis for the study using an online sample size calculator (calculator.net, 2021). 95% confidence level and 4.6% margin of error was used to calculate the sample size of 449 respondents determining the level of accuracy of the sample from the total estimated population of 38,734 women aged 18-69 years in Mwea East sub County.Data CollectionThe administration of the questionnaire was done by the Principal Investigator (PI) along with the KIIs, which were conducted after the questionnaire had been administered. The questionnaires were administered by 11 data collection assistants who were trained by the researcher. One of the 11 data collectors was the team leader. The researcher collected data in 5 of the households to demonstrate and practice the data collection process. Data AnalysisQuantitative and qualitative data were analyzed and triangulated to validate the findings. The quantitative data was analyzed using a combination of the IBM SPSS techniques including frequencies, cross-tabulations, bivariate statistics, means, correlations and descriptive ratio statistics. Qualitative data from both respondents and key informants’ interviews were documented using filed notes and thematically analyzed. The analysis from both sets of data was then merged to present the results.

    Authors: Mao Xiaohua;

    In recent years, in order to promote the independent development of the new energy vehicle industry, Chinese government has decided to reduce the consumption subsidies for new energy vehicles until the subsidies are completely withdrawn. The reduction of consumption subsidy has a great impact on the production and sales of new energy vehicles in the whole vehicle market. However, does the reduction of this subsidy also have an impact on other enterprises in the new energy vehicles industry chain? This paper tests this problem using data from 2016 to 2018, and finds, through empirical analysis, that during the period of subsidy decline, the profitability of component enterprises is significantly positively correlated with this subsidies, while the r&d investment of enterprises is significantly negatively correlated with this subsidies. The results show that in terms of profitability, the reduction of consumer subsidies not only has an impact on the whole vehicle industry of new energy vehicles, but also has an adverse impact on the core component companies in the industrial chain. However, in terms of r&d, the reduction of subsidies has more negatively strengthened the input and attention of R&D in component companies.

  • Authors: Jo-Anne Ferreira; Charles Arcodia; Debbie Cotterell;

    An important outcome of a university business education is to shape individuals who are capable of working in and operating businesses that deliver economically profitable, socially responsible and ecologically viable services. In preparing future sustainable tourism workers, universities also need to design curricula that develop students’ skills in critical thinking and acting with a sense of ethics and empathy. Research evidence indicates, however, that students often graduate without these skills. A potential reason for this is the design of tourism curricula based on weaker conceptualisations of sustainability (e.g. triple bottom line) as opposed to stronger conceptualisations of sustainability (more holistic and inclusive approaches). Another possible reason could be that educators are not successfully cultivating students’ abilities to think in more complex ways about sustainability nor are they adequately acknowledging the ways in which their students make sense of a complex concept such as sustainability. To add to the complexity of the sustainability phenomenon, there is growing international pressure on the tourism industry by the United Nations (UN) to work towards achieving the 17 global sustainable development goals (SDGs) by 2030. Despite recognition that tourism can help contribute towards the SDGs, a UN report provides evidence that tourism policymakers are not actively and sufficiently engaging with the SDGs. The UN’s recognition of the tourism industry’s ability to advance the SDGS through economic growth (SDG 8) is further problematic, even if this is seen as sustainable economic growth. The term ‘sustainable development’ has long been contested as a weaker form of sustainability due to its progrowth and development emphasis. Given the current global overtourism crisis, it seems more important than ever that universities pay attention to how sustainable tourism is being interpreted and implemented. This is necessary if educators are to truly encourage stronger sustainability mindsets in future tourism workers and change makers. Therefore, the overarching aim of this thesis is to explore how conceptualisations of strong sustainability amongst university students can be strengthened. This study is the first to explore the usefulness of variation theory in strengthening conceptualisations of strong sustainability amongst university tourism students. It provides the tourism literature with evidence of: 1) the conceptualisation of sustainability currently being integrated into undergraduate tourism courses by universities internationally; 2) the benefits of phenomenography as a research approach for studying qualitative difference in understanding concepts such as sustainability and sustainable tourism; 3) the viability of using a learning study approach to develop ‘stronger’ understandings of sustainability; and 4) the potential of variation theory to explain how individuals acquire understandings of sustainability. The empirical research is presented in three studies to address three main research objectives. The first research objective was ‘to identify the conceptualisations of sustainability currently being used in university undergraduate sustainable tourism courses internationally’. The first study, in Chapter III, identifies whether ‘strong sustainability’, sustainability skills and the SDGs are currently underpinning 60 international sustainable tourism courses. Chapter IV ‘explores the different ways in which tourism students, academics and industry practitioners currently conceptualise sustainability’ by conducting phenomenographic interviews with 20 participants. A continuum of less to more complex understandings of sustainability was then developed to identify qualitatively different ways of understanding sustainability. The third research objective was ‘to investigate alternate teaching and learning approaches that might encourage stronger conceptualisations of sustainability amongst undergraduate tourism students’. Chapter V, discusses how the continuum explored in Chapter IV was used in an Australian university sustainable tourism course, underpinned by variation theory, to implement a learning study to enhance students’ understandings of sustainability and the conceptual complexity of the term sustainability. The findings revealed that internationally, sustainable tourism courses do not include ‘very strong’ conceptualisations of sustainability, and that sustainability pedagogies (such as systems and holistic thinking) are not widely used. Phenomenographic interviews with (predominantly Australian-based) lecturers, students and industry workers initially revealed four qualitatively different ways of understanding sustainability ranging from weak to very strong understandings of sustainability. Whilst many tourism lecturers seemed to show understandings of moderate to strong sustainability, very few showed very strong sustainability conceptualisations. This implies that some tourism courses may potentially be designed and underpinned by a weak to moderate articulation of sustainability. These interviews also revealed that industry owners tended to demonstrate a much stronger sustainability understanding than tourism lecturers. Most industry owners had a longer-term focus and key motives centred on giving back to society and a ‘pay-it-forward’ attitude towards the environment. Further findings in the learning study revealed that variation theory offers a valuable teaching and learning strategy to help develop more complex conceptualisations of ‘very strong’ sustainability within a university tourism course. Based on these findings, a number of implications for theory and practice are examined. These include recommendations regarding the design of sustainable tourism courses such as strengthening the sustainability conceptualisations underpinning them; better integration of the SDGs; and the development of critical and systems thinking skills. The three studies also provide examples for use in practice. For example, in Chapter III, a questioning strategy is provided. The phenomenographic continuum in Chapter IV provides a teaching and learning tool for educators to incorporate into sustainability courses to help students’ understandings of the phenomena. Chapter V provides insight into how this continuum can be incorporated into a learning study and provides practical ways of using variation theory. By implementing the continuum into teaching and learning activities, both educators and industry can develop deeper and stronger conceptualisations of sustainability for the tourism industry. Limitations of the study are discussed, and recommendations put forward for future research. In addition, ways in which educational institutions and governments can use the findings of the study to enhance teaching and learning, both in the classroom and industry workplaces, are discussed. Such enhancements will provide a foundation of ‘strong sustainability’ mindsets within our future tourism industry, which in turn will contribute to the 2030 SDGs being achieved.

    Authors: Davies, Simon;

    Achieving reductions in global anthropogenic emissions necessary to mitigate the worst effects of climate change will require significant reductions in energy demand. However, there are concerns that energy demand reductions involving lifestyle and behavioural changes might negatively impact peoples’ wellbeing. The work in this thesis studies the impacts of how people spend their time – commonly known as time-use – to try to understand whether this is the true, or whether energy demand could be reduced while improving wellbeing. Using the UK as a case study, this issue is examined by determining the energy use and wellbeing attributes of different activities and lifestyles, by modelling the impacts of shifts in time-use between activities, and by comparing the importance of three specific changes that might impact future energy use and wellbeing. Firstly, based upon existing literature it is identified that there is a need to better understand the combined energy and wellbeing impacts of different activities and lifestyles. Combining UK time-use and energy consumption data, the energy intensity, enjoyment and sociability of time is studied. Comparing these metrics for different activities suggests that since the most enjoyable (and in some cases sociable) activities are generally the least energy-intensive, acceptable (or popular) lifestyle changes might exist that reduce national energy use and improve wellbeing. However, studying changes between 2000 and 2015 shows that while the population’s time became less energy-intensive, there was little change in average enjoyment and a reduction in sociability. Segmenting the population by age reveals that an ageing population could present a challenge since energy use broadly increases with age-group while social contact reduces. However, comparing occupations highlights opportunities for specific actions that could improve wellbeing and reduce energy use, while regional differences suggest that wellbeing might be improved without increasing energy use. Having determined the energy intensity and wellbeing associated with different uses of time, the impacts of possible time-use changes are then studied. Acknowledging the difficulty in trying to predict how people might choose to re-allocate time in different situations, a sensitivity-based approach is used to study the impacts of a wide range of possible shifts in time between activities. The approach is then applied to explore the impacts of extreme lifestyle changes associated with COVID-19 lockdown measures in the UK and validated against real-world observations during the pandemic. While activity changes associated with lockdown measures reduce energy use, there are varying implications for peoples’ wellbeing, with the youngest appearing to be most negatively impacted but those able to work from home potentially benefiting. Although lockdown measures prevented some of the most enjoyable and sociable activities from happening, alternative activity changes could be supported in future that reduce energy use while improving wellbeing. Finally, time is used as a basis to compare the importance of different types of changes and help to prioritise actions. This is demonstrated by studying the combined impacts of three example changes – greater home working, changes in commuting transport modes and car intensity – on office workers’ energy use and wellbeing. The results show that working from home could have a greater impact upon office workers’ average energy use and enjoyment than changes to commuting modes, but that the social contact provided by the office could be difficult to replace. The study also demonstrates different ways that energy savings might be achieved through home working, shifts in commuting modes and changes to vehicle intensity. This approach could be used more widely to compare a broader range of changes, understand their interactions and different ways to achieve outcomes, and help to identify those changes that are most important to reduce energy use and improve wellbeing. The work presented in this thesis shows that time-use can be used as a basis to examine energy demand and wellbeing together. Using time-use to link these issues enables trade-offs or co-benefits due to different uses of time to be determined and allows rebound effects to be considered. The results suggest that reducing energy use can be achieved at the same time as improving wellbeing. The hope is that the approaches and findings presented in this thesis can provide a basis for wider discussion and a platform for future work to support climate change mitigation strategies that are positive for both the environment and society.

  • Authors: Sikha Karki;

    Climate change is a pervasive global issue that threatens the livelihoods and wellbeing of billions living globally. Climate change is a risk multiplier impacting all ecosystems, society, and sectors of the economy. The agriculture sector is one such sector that is highly vulnerable to changes in climate. In a country like Nepal where rainfed agriculture is a dominant occupation and a key pillar of the country’s economy, climate change brings risks and negative consequences for on-farm production, farmers' livelihoods as well as on the country’s development. The impacts of climate change including rising temperatures, an increase in the frequency or intensity of extreme weather events such as drought, and shifts in the rainfall seasonality, can cause a decline in food production and threaten the quality of food supplies, leading to reduced food security. The rise in the global population will increase global demand for food which implies that agriculture needs to boost production and increase yields, among other things. The unprecedented risks posed by climate change potentially undermine the ability of farms and farm holders to grow adequate and quality food. The severity of these risks varies due to a range of underlying factors including low economic development, their location, existing biophysical and socioeconomic conditions, and institutional arrangements. While the impacts of climate change on food production as well as agricultural practices in Nepal have been documented, there is a dearth in scholarly literature that has assessed the impacts of climate change on household food security in Nepal incorporating farmers’ perspectives and in particular smallholder subsistence farmers. Furthermore, there is only modest literature that has examined geographical variations in those experiences and understandings. This PhD study aimed, therefore, to investigate the effects of climate change on agricultural practices and food security, with a focus on subsistence smallholder farmers in three main agro- ecological zones of Nepal known as The Mountains, Hills, and the Terai. The study aimed to respond to the primary research question: How are Nepalese farming communities being impacted by climate change and how are they responding to ensure their continued food security? To answer this main research, question the study posed the following secondary research questions: Q1. How is climate changing and how is it impacting subsistence agriculture? Q2. What are the farmers experiencing and what is their understanding? a. Are there gender differences in understanding and experiencing? Q3. What is the state of food insecurity among these farmers? a. How is it being impacted by climate change? Q4. What adaptation strategies have been adopted by smallholder farmers to address threats to agricultural practices and food security from climate change and other pressures? Both the qualitative and qualitative data were collected using multiple methods to address the identified research questions. Methods included a narrative literature review, systematic review, face to face interviews with farmers, individual interviews with key informants and focus groups with the women's group. Climate data on temperature between 1971-2013 and rainfall between 1967-2013 were analysed. Additionally, secondary data on crop yield from 1980 to 2016 were also analysed to gain a better empirical understanding of the relations between climate change and yield pattern and to triangulate and validate the findings from the interviews. Quantitative data on cereal crop yields and climate data were systematically tabulated and further statistically analysed using software R. This study employed the Bayesian approach to statistical modelling. Besides, this study undertook an integrated risk assessment of food insecurity using the Bayesian Belief Network model to reflect how the risk of food insecurity is influenced under two scenarios: (1) current climate conditions and (2) the influences of different adaptation strategies employed. NVivo was used for content analysis for qualitative data obtained from the key informant interview and focus group data and analysis of transcripts from farmers' structured interviews. The findings showed that agricultural practices have undergone various changes over the past 30 years. Climate change impacts were experienced by farmers in all three agro-ecological zones of Nepal. However, the impacts varied between these zones in terms of frequency and intensity. The effect of climate change was highly pronounced in the Mountains zone followed by the Hills and the Terai. The results confirmed that rural subsistence smallholder farmers dependent on rainfed agriculture are vulnerable to climate change impacts. Moreover, it disproportionately affects the poor farmers whose income hinges solely on agriculture and associated activities. Boosting agricultural production and empowering these smallholders is key to enhancing their food security. The experiences reported by farmers are well aligned with the trend of the climatic variables obtained from climate data analysis, highlighting the importance of perception-based survey in complementing climate research. The study demonstrated both the climatic and non-climatic factors are affecting agricultural practices as well as household food security of these farming communities. It is, therefore, difficult to isolate the influence of any of these factors. This was supported by the findings from the risk assessment undertaken by Bayesian modelling. Based on Bayesian modelling, the smallholder farmers mainly at the Mountain zone were at the risk of food insecurity. The measures to increase the adaptive capacity of these smallholders were found to help them manage the risk of food insecurity. Addressing the complicated and multifaceted concerns of climate change and food security needs multidisciplinary and multisectoral adaptation interventions acknowledging underlying biophysical, social, economic, geographical and environmental circumstances. Farmers have taken some actions to adapt and reduce the worsening impacts of climate change. Nevertheless, farmers encountered several barriers in effectively adapting to climate change. This study concluded there is an urgent need for a transformative level of intervention that warrants a coordinated action and collaboration between relevant stakeholders working in this field, including governments and non-governmental organizations, to target the most vulnerable and the needy smallholder farmers addressing the constraints and pressures they face. Policy and decision-makers should work extensively and sensitively with smallholders to ensure the maintenance of their livelihood and to guarantee their food security. Combining local and scientific knowledge is needed to help direct research and tailor adaptation solutions that meet local conditions and needs.

  • This thesis shows how the Process Analysis Method (PAM) can be applied to assess technologies used to mitigate arsenic from drinking water in rural India, using a set of sustainability indicators. Stakeholder perspectives, gathered from a fieldwork survey of 933 households in West Bengal in 2012, played a significant role in this assessment. This research found that the ‘Most Important’ issues as specified by the technology users are cost, trust, distance from their home to the clean water source (an indicator of convenience), and understanding the health effects of arsenic. It was also found that none of the ten technologies evaluated are economically viable, as many do not charge user-fees, which creates reliance upon donations to meet recurring costs. Utilisation of a technology is strongly related to sociocultural capital, but in many cases, features that contribute to sociocultural value, like regular testing of the treated water, are not included in the financial budget. It is suggested that increased awareness might change attitudes to arsenic-rich waste and its disposal protocols. This waste is often currently discarded in an uncontrolled manner in the local environment, giving rise to the possibility of point-source recontamination. All technologies proved to have difficulties in dealing with waste, except the Tipot and Dug wells which produce no waste. Of the methods considered, the BESU technology scored highest, but still only with 47-62% of the maximum scores achievable within each domain. This explains the widespread failure of mitigation projects across the region. The indicators and metrics show where improvements can be made. A model scheme based on these findings is outlined which could be applied with the objective of increasing utilisation and improving sustainability. It can be concluded that a product stewardship approach should be taken in regard to design, implementation and operation of the technologies, including the creation of a regulated toxic waste collection and disposal industry.

    The 3th Continental Legume Innovation Network (C-LIN) workshop was held on the 16th - 17th of September 2019 in Ljubljana, Slovenia, hosted by the Jozef Stefan Institute and co-hosted by the University of Hohenheim. The meeting brought together actors and professionals involved in all parts of the regional legume agri-food chain (LAFC), to interact with members of the TRUE project. The project TRUE (TRansition paths to sUstainable legume-based systems in Europe) is involved in the development of European strategies for the sustainable production and use of plant proteins obtained from legumes. An increase in production of legumes is expected to lower the usage of non-renewable resources used in the production of mineral fertilisers. It will also improve crop diversity and increase human and animal consumption of legumes. An important objective of the project TRUE is to assess environmental, social and economic benefits of incorporating legumes into agri-food chains, as well as to investigate in what way such incorporation is meeting the key goals of sustainable development. The task of the TRUE project is also to engage with different stakeholders in the LAFC. Therefore, the workshops participants were representatives of growers, food industry, transport, trade and consumers, whose activities already incorporate legumes or who are planning to do so. On the first day of the workshop, we focused on assessing the key sustainability aspects of individual links within the LAFC as well as the chain as a whole. The knowledge gained will help the workshop participants to reach sustainable development targets in their own area of work. Researchers as well as stakeholders taking part in the TRUE project, through the workshop discussions, obtained useful information that will be used for future development of the evaluation model for the assessment of sustainability of the LAFC. Day two focused on knowledge exchange, showcasing examples of good practice during a field trip. The participants first visited the company Žito d.o.o, a food company that, while modern, maintains its roots in a rich and prosperous tradition. They are constantly following the trends and successfully introducing them into modern production technology with a revolutionary market approach, which includes legumes. The next stop was Semenarna Ljubljana – a seed and packing company. Semenarna Ljubljana is one of the region’s top providers of quality seeds. Their development is based on their own crops, products and services. They maintain over 70 different seed varieties from 26 plant species (including common beans, soybeans, peas, chickpeas and lentils), of which 37 are indigenous Slovenian varieties. The last stop was at the Etri community, a leading group in the field of social entrepreneurship, whose aims are to build an inclusive society and change social norms. They are changing their practice in the fields of ecology, ergonomics and ethical economics. The story of the Etri community is about creating green jobs for individuals, often excluded from society, in collaboration with socially responsible companies. They intend to include more legumes in their meals and at the end of the visit they prepared a delicious legumes showcase lunch for the delegates. The whole event focused on the five links of the LAFC. 43 participants (21 females and 22 males) attended the workshop, of which six were TRUE members that acted as facilitators and four were invited government guest that discussed different aspects of LAFC related topics: regulatory organizations, education and knowledge transfer, financial and business mechanisms and public participation.

    AbstractWith the global economy not yet 10% circular, businesses are key stakeholders in designing new forms of resource use, especially large multinationals. However, compared with the wealth of studies on ‘born sustainable’ start‐ups, there is minimal case study or interview based research into how incumbent companies are approaching this transition. Focusing on plastics, we ask: how does one incumbent multinational company approach the circular economy transition? This paper presents a case study of the incumbent multinational chemical company Dow, a leading plastics manufacturer. Varied external stressors and drivers for the circular economy act upon a company (which also has its own imperatives), resulting in tentative steps towards circular economy. To date, these steps have tweaked the existing system rather than radically altering the business model. For companies, like for the entire global economy, this transition has only just begun. This paper identifies key drivers, enablers and barriers of the circular economy, none of which are fixed or immutable. Knowing which levers for change are available and effective could help policy makers to shift gear to enable quicker progress towards circularity. Overall, broad based support and engagement is needed to progress the circular economy, hence all stakeholders have roles to play in demanding and enacting circular practices.

    Authors: Steinbuks, J.; Neuhoff, K.;

    This paper estimates the vintage capital model of energy demand and examines operational and investment responses to energy prices at disaggregate level using data from five OECD manufacturing industries. Applying the model to less aggregate level data helps avoiding the distortions from exogenous structural shifts and measurement errors. The results confirm the previous findings that including capital stock vintages significantly improves the econometric model's goodness of fit. Estimated own-price elasticities of energy demand vary between 0.26 and 1.00 and are economically sound. Estimated own-price investment elasticities of energy efficiency of capital stock vary between 0.03 and 0.9. The investment response to energy prices thus varies significantly across manufacturing industries, being significant in some of them and negligible in other. The results of policy simulations for the U.K. petrochemical industry (the most energy-intensive industry in the sample) indicate that total (operational and investment) own-price elasticity of energy demand is close to one.

    Study PopulationThe target population of the study were women aged 18 years to 69 years from households in Mwea East sub County that have experienced climate change events. As shown in table 3.1 below, the total population of female in Mwea East sub County in this age category was estimated at 38,734 (Kenya National Bureau of Statistics (KNBS)Volume III, table 2.5, (2019).Sample SizeA sample size of 449 respondents was determined as adequate for statistical analysis for the study using an online sample size calculator (calculator.net, 2021). 95% confidence level and 4.6% margin of error was used to calculate the sample size of 449 respondents determining the level of accuracy of the sample from the total estimated population of 38,734 women aged 18-69 years in Mwea East sub County.Data CollectionThe administration of the questionnaire was done by the Principal Investigator (PI) along with the KIIs, which were conducted after the questionnaire had been administered. The questionnaires were administered by 11 data collection assistants who were trained by the researcher. One of the 11 data collectors was the team leader. The researcher collected data in 5 of the households to demonstrate and practice the data collection process. Data AnalysisQuantitative and qualitative data were analyzed and triangulated to validate the findings. The quantitative data was analyzed using a combination of the IBM SPSS techniques including frequencies, cross-tabulations, bivariate statistics, means, correlations and descriptive ratio statistics. Qualitative data from both respondents and key informants’ interviews were documented using filed notes and thematically analyzed. The analysis from both sets of data was then merged to present the results.

    Authors: Mao Xiaohua;

    In recent years, in order to promote the independent development of the new energy vehicle industry, Chinese government has decided to reduce the consumption subsidies for new energy vehicles until the subsidies are completely withdrawn. The reduction of consumption subsidy has a great impact on the production and sales of new energy vehicles in the whole vehicle market. However, does the reduction of this subsidy also have an impact on other enterprises in the new energy vehicles industry chain? This paper tests this problem using data from 2016 to 2018, and finds, through empirical analysis, that during the period of subsidy decline, the profitability of component enterprises is significantly positively correlated with this subsidies, while the r&d investment of enterprises is significantly negatively correlated with this subsidies. The results show that in terms of profitability, the reduction of consumer subsidies not only has an impact on the whole vehicle industry of new energy vehicles, but also has an adverse impact on the core component companies in the industrial chain. However, in terms of r&d, the reduction of subsidies has more negatively strengthened the input and attention of R&D in component companies.

    An important outcome of a university business education is to shape individuals who are capable of working in and operating businesses that deliver economically profitable, socially responsible and ecologically viable services. In preparing future sustainable tourism workers, universities also need to design curricula that develop students’ skills in critical thinking and acting with a sense of ethics and empathy. Research evidence indicates, however, that students often graduate without these skills. A potential reason for this is the design of tourism curricula based on weaker conceptualisations of sustainability (e.g. triple bottom line) as opposed to stronger conceptualisations of sustainability (more holistic and inclusive approaches). Another possible reason could be that educators are not successfully cultivating students’ abilities to think in more complex ways about sustainability nor are they adequately acknowledging the ways in which their students make sense of a complex concept such as sustainability. To add to the complexity of the sustainability phenomenon, there is growing international pressure on the tourism industry by the United Nations (UN) to work towards achieving the 17 global sustainable development goals (SDGs) by 2030. Despite recognition that tourism can help contribute towards the SDGs, a UN report provides evidence that tourism policymakers are not actively and sufficiently engaging with the SDGs. The UN’s recognition of the tourism industry’s ability to advance the SDGS through economic growth (SDG 8) is further problematic, even if this is seen as sustainable economic growth. The term ‘sustainable development’ has long been contested as a weaker form of sustainability due to its progrowth and development emphasis. Given the current global overtourism crisis, it seems more important than ever that universities pay attention to how sustainable tourism is being interpreted and implemented. This is necessary if educators are to truly encourage stronger sustainability mindsets in future tourism workers and change makers. Therefore, the overarching aim of this thesis is to explore how conceptualisations of strong sustainability amongst university students can be strengthened. This study is the first to explore the usefulness of variation theory in strengthening conceptualisations of strong sustainability amongst university tourism students. It provides the tourism literature with evidence of: 1) the conceptualisation of sustainability currently being integrated into undergraduate tourism courses by universities internationally; 2) the benefits of phenomenography as a research approach for studying qualitative difference in understanding concepts such as sustainability and sustainable tourism; 3) the viability of using a learning study approach to develop ‘stronger’ understandings of sustainability; and 4) the potential of variation theory to explain how individuals acquire understandings of sustainability. The empirical research is presented in three studies to address three main research objectives. The first research objective was ‘to identify the conceptualisations of sustainability currently being used in university undergraduate sustainable tourism courses internationally’. The first study, in Chapter III, identifies whether ‘strong sustainability’, sustainability skills and the SDGs are currently underpinning 60 international sustainable tourism courses. Chapter IV ‘explores the different ways in which tourism students, academics and industry practitioners currently conceptualise sustainability’ by conducting phenomenographic interviews with 20 participants. A continuum of less to more complex understandings of sustainability was then developed to identify qualitatively different ways of understanding sustainability. The third research objective was ‘to investigate alternate teaching and learning approaches that might encourage stronger conceptualisations of sustainability amongst undergraduate tourism students’. Chapter V, discusses how the continuum explored in Chapter IV was used in an Australian university sustainable tourism course, underpinned by variation theory, to implement a learning study to enhance students’ understandings of sustainability and the conceptual complexity of the term sustainability. The findings revealed that internationally, sustainable tourism courses do not include ‘very strong’ conceptualisations of sustainability, and that sustainability pedagogies (such as systems and holistic thinking) are not widely used. Phenomenographic interviews with (predominantly Australian-based) lecturers, students and industry workers initially revealed four qualitatively different ways of understanding sustainability ranging from weak to very strong understandings of sustainability. Whilst many tourism lecturers seemed to show understandings of moderate to strong sustainability, very few showed very strong sustainability conceptualisations. This implies that some tourism courses may potentially be designed and underpinned by a weak to moderate articulation of sustainability. These interviews also revealed that industry owners tended to demonstrate a much stronger sustainability understanding than tourism lecturers. Most industry owners had a longer-term focus and key motives centred on giving back to society and a ‘pay-it-forward’ attitude towards the environment. Further findings in the learning study revealed that variation theory offers a valuable teaching and learning strategy to help develop more complex conceptualisations of ‘very strong’ sustainability within a university tourism course. Based on these findings, a number of implications for theory and practice are examined. These include recommendations regarding the design of sustainable tourism courses such as strengthening the sustainability conceptualisations underpinning them; better integration of the SDGs; and the development of critical and systems thinking skills. The three studies also provide examples for use in practice. For example, in Chapter III, a questioning strategy is provided. The phenomenographic continuum in Chapter IV provides a teaching and learning tool for educators to incorporate into sustainability courses to help students’ understandings of the phenomena. Chapter V provides insight into how this continuum can be incorporated into a learning study and provides practical ways of using variation theory. By implementing the continuum into teaching and learning activities, both educators and industry can develop deeper and stronger conceptualisations of sustainability for the tourism industry. Limitations of the study are discussed, and recommendations put forward for future research. In addition, ways in which educational institutions and governments can use the findings of the study to enhance teaching and learning, both in the classroom and industry workplaces, are discussed. Such enhancements will provide a foundation of ‘strong sustainability’ mindsets within our future tourism industry, which in turn will contribute to the 2030 SDGs being achieved.

    Authors: Davies, Simon;

    Achieving reductions in global anthropogenic emissions necessary to mitigate the worst effects of climate change will require significant reductions in energy demand. However, there are concerns that energy demand reductions involving lifestyle and behavioural changes might negatively impact peoples’ wellbeing. The work in this thesis studies the impacts of how people spend their time – commonly known as time-use – to try to understand whether this is the true, or whether energy demand could be reduced while improving wellbeing. Using the UK as a case study, this issue is examined by determining the energy use and wellbeing attributes of different activities and lifestyles, by modelling the impacts of shifts in time-use between activities, and by comparing the importance of three specific changes that might impact future energy use and wellbeing. Firstly, based upon existing literature it is identified that there is a need to better understand the combined energy and wellbeing impacts of different activities and lifestyles. Combining UK time-use and energy consumption data, the energy intensity, enjoyment and sociability of time is studied. Comparing these metrics for different activities suggests that since the most enjoyable (and in some cases sociable) activities are generally the least energy-intensive, acceptable (or popular) lifestyle changes might exist that reduce national energy use and improve wellbeing. However, studying changes between 2000 and 2015 shows that while the population’s time became less energy-intensive, there was little change in average enjoyment and a reduction in sociability. Segmenting the population by age reveals that an ageing population could present a challenge since energy use broadly increases with age-group while social contact reduces. However, comparing occupations highlights opportunities for specific actions that could improve wellbeing and reduce energy use, while regional differences suggest that wellbeing might be improved without increasing energy use. Having determined the energy intensity and wellbeing associated with different uses of time, the impacts of possible time-use changes are then studied. Acknowledging the difficulty in trying to predict how people might choose to re-allocate time in different situations, a sensitivity-based approach is used to study the impacts of a wide range of possible shifts in time between activities. The approach is then applied to explore the impacts of extreme lifestyle changes associated with COVID-19 lockdown measures in the UK and validated against real-world observations during the pandemic. While activity changes associated with lockdown measures reduce energy use, there are varying implications for peoples’ wellbeing, with the youngest appearing to be most negatively impacted but those able to work from home potentially benefiting. Although lockdown measures prevented some of the most enjoyable and sociable activities from happening, alternative activity changes could be supported in future that reduce energy use while improving wellbeing. Finally, time is used as a basis to compare the importance of different types of changes and help to prioritise actions. This is demonstrated by studying the combined impacts of three example changes – greater home working, changes in commuting transport modes and car intensity – on office workers’ energy use and wellbeing. The results show that working from home could have a greater impact upon office workers’ average energy use and enjoyment than changes to commuting modes, but that the social contact provided by the office could be difficult to replace. The study also demonstrates different ways that energy savings might be achieved through home working, shifts in commuting modes and changes to vehicle intensity. This approach could be used more widely to compare a broader range of changes, understand their interactions and different ways to achieve outcomes, and help to identify those changes that are most important to reduce energy use and improve wellbeing. The work presented in this thesis shows that time-use can be used as a basis to examine energy demand and wellbeing together. Using time-use to link these issues enables trade-offs or co-benefits due to different uses of time to be determined and allows rebound effects to be considered. The results suggest that reducing energy use can be achieved at the same time as improving wellbeing. The hope is that the approaches and findings presented in this thesis can provide a basis for wider discussion and a platform for future work to support climate change mitigation strategies that are positive for both the environment and society.

  • Authors: Sikha Karki;

    Climate change is a pervasive global issue that threatens the livelihoods and wellbeing of billions living globally. Climate change is a risk multiplier impacting all ecosystems, society, and sectors of the economy. The agriculture sector is one such sector that is highly vulnerable to changes in climate. In a country like Nepal where rainfed agriculture is a dominant occupation and a key pillar of the country’s economy, climate change brings risks and negative consequences for on-farm production, farmers' livelihoods as well as on the country’s development. The impacts of climate change including rising temperatures, an increase in the frequency or intensity of extreme weather events such as drought, and shifts in the rainfall seasonality, can cause a decline in food production and threaten the quality of food supplies, leading to reduced food security. The rise in the global population will increase global demand for food which implies that agriculture needs to boost production and increase yields, among other things. The unprecedented risks posed by climate change potentially undermine the ability of farms and farm holders to grow adequate and quality food. The severity of these risks varies due to a range of underlying factors including low economic development, their location, existing biophysical and socioeconomic conditions, and institutional arrangements. While the impacts of climate change on food production as well as agricultural practices in Nepal have been documented, there is a dearth in scholarly literature that has assessed the impacts of climate change on household food security in Nepal incorporating farmers’ perspectives and in particular smallholder subsistence farmers. Furthermore, there is only modest literature that has examined geographical variations in those experiences and understandings. This PhD study aimed, therefore, to investigate the effects of climate change on agricultural practices and food security, with a focus on subsistence smallholder farmers in three main agro- ecological zones of Nepal known as The Mountains, Hills, and the Terai. The study aimed to respond to the primary research question: How are Nepalese farming communities being impacted by climate change and how are they responding to ensure their continued food security? To answer this main research, question the study posed the following secondary research questions: Q1. How is climate changing and how is it impacting subsistence agriculture? Q2. What are the farmers experiencing and what is their understanding? a. Are there gender differences in understanding and experiencing? Q3. What is the state of food insecurity among these farmers? a. How is it being impacted by climate change? Q4. What adaptation strategies have been adopted by smallholder farmers to address threats to agricultural practices and food security from climate change and other pressures? Both the qualitative and qualitative data were collected using multiple methods to address the identified research questions. Methods included a narrative literature review, systematic review, face to face interviews with farmers, individual interviews with key informants and focus groups with the women's group. Climate data on temperature between 1971-2013 and rainfall between 1967-2013 were analysed. Additionally, secondary data on crop yield from 1980 to 2016 were also analysed to gain a better empirical understanding of the relations between climate change and yield pattern and to triangulate and validate the findings from the interviews. Quantitative data on cereal crop yields and climate data were systematically tabulated and further statistically analysed using software R. This study employed the Bayesian approach to statistical modelling. Besides, this study undertook an integrated risk assessment of food insecurity using the Bayesian Belief Network model to reflect how the risk of food insecurity is influenced under two scenarios: (1) current climate conditions and (2) the influences of different adaptation strategies employed. NVivo was used for content analysis for qualitative data obtained from the key informant interview and focus group data and analysis of transcripts from farmers' structured interviews. The findings showed that agricultural practices have undergone various changes over the past 30 years. Climate change impacts were experienced by farmers in all three agro-ecological zones of Nepal. However, the impacts varied between these zones in terms of frequency and intensity. The effect of climate change was highly pronounced in the Mountains zone followed by the Hills and the Terai. The results confirmed that rural subsistence smallholder farmers dependent on rainfed agriculture are vulnerable to climate change impacts. Moreover, it disproportionately affects the poor farmers whose income hinges solely on agriculture and associated activities. Boosting agricultural production and empowering these smallholders is key to enhancing their food security. The experiences reported by farmers are well aligned with the trend of the climatic variables obtained from climate data analysis, highlighting the importance of perception-based survey in complementing climate research. The study demonstrated both the climatic and non-climatic factors are affecting agricultural practices as well as household food security of these farming communities. It is, therefore, difficult to isolate the influence of any of these factors. This was supported by the findings from the risk assessment undertaken by Bayesian modelling. Based on Bayesian modelling, the smallholder farmers mainly at the Mountain zone were at the risk of food insecurity. The measures to increase the adaptive capacity of these smallholders were found to help them manage the risk of food insecurity. Addressing the complicated and multifaceted concerns of climate change and food security needs multidisciplinary and multisectoral adaptation interventions acknowledging underlying biophysical, social, economic, geographical and environmental circumstances. Farmers have taken some actions to adapt and reduce the worsening impacts of climate change. Nevertheless, farmers encountered several barriers in effectively adapting to climate change. This study concluded there is an urgent need for a transformative level of intervention that warrants a coordinated action and collaboration between relevant stakeholders working in this field, including governments and non-governmental organizations, to target the most vulnerable and the needy smallholder farmers addressing the constraints and pressures they face. Policy and decision-makers should work extensively and sensitively with smallholders to ensure the maintenance of their livelihood and to guarantee their food security. Combining local and scientific knowledge is needed to help direct research and tailor adaptation solutions that meet local conditions and needs.

  • This thesis shows how the Process Analysis Method (PAM) can be applied to assess technologies used to mitigate arsenic from drinking water in rural India, using a set of sustainability indicators. Stakeholder perspectives, gathered from a fieldwork survey of 933 households in West Bengal in 2012, played a significant role in this assessment. This research found that the ‘Most Important’ issues as specified by the technology users are cost, trust, distance from their home to the clean water source (an indicator of convenience), and understanding the health effects of arsenic. It was also found that none of the ten technologies evaluated are economically viable, as many do not charge user-fees, which creates reliance upon donations to meet recurring costs. Utilisation of a technology is strongly related to sociocultural capital, but in many cases, features that contribute to sociocultural value, like regular testing of the treated water, are not included in the financial budget. It is suggested that increased awareness might change attitudes to arsenic-rich waste and its disposal protocols. This waste is often currently discarded in an uncontrolled manner in the local environment, giving rise to the possibility of point-source recontamination. All technologies proved to have difficulties in dealing with waste, except the Tipot and Dug wells which produce no waste. Of the methods considered, the BESU technology scored highest, but still only with 47-62% of the maximum scores achievable within each domain. This explains the widespread failure of mitigation projects across the region. The indicators and metrics show where improvements can be made. A model scheme based on these findings is outlined which could be applied with the objective of increasing utilisation and improving sustainability. It can be concluded that a product stewardship approach should be taken in regard to design, implementation and operation of the technologies, including the creation of a regulated toxic waste collection and disposal industry.

    The 3th Continental Legume Innovation Network (C-LIN) workshop was held on the 16th - 17th of September 2019 in Ljubljana, Slovenia, hosted by the Jozef Stefan Institute and co-hosted by the University of Hohenheim. The meeting brought together actors and professionals involved in all parts of the regional legume agri-food chain (LAFC), to interact with members of the TRUE project. The project TRUE (TRansition paths to sUstainable legume-based systems in Europe) is involved in the development of European strategies for the sustainable production and use of plant proteins obtained from legumes. An increase in production of legumes is expected to lower the usage of non-renewable resources used in the production of mineral fertilisers. It will also improve crop diversity and increase human and animal consumption of legumes. An important objective of the project TRUE is to assess environmental, social and economic benefits of incorporating legumes into agri-food chains, as well as to investigate in what way such incorporation is meeting the key goals of sustainable development. The task of the TRUE project is also to engage with different stakeholders in the LAFC. Therefore, the workshops participants were representatives of growers, food industry, transport, trade and consumers, whose activities already incorporate legumes or who are planning to do so. On the first day of the workshop, we focused on assessing the key sustainability aspects of individual links within the LAFC as well as the chain as a whole. The knowledge gained will help the workshop participants to reach sustainable development targets in their own area of work. Researchers as well as stakeholders taking part in the TRUE project, through the workshop discussions, obtained useful information that will be used for future development of the evaluation model for the assessment of sustainability of the LAFC. Day two focused on knowledge exchange, showcasing examples of good practice during a field trip. The participants first visited the company Žito d.o.o, a food company that, while modern, maintains its roots in a rich and prosperous tradition. They are constantly following the trends and successfully introducing them into modern production technology with a revolutionary market approach, which includes legumes. The next stop was Semenarna Ljubljana – a seed and packing company. Semenarna Ljubljana is one of the region’s top providers of quality seeds. Their development is based on their own crops, products and services. They maintain over 70 different seed varieties from 26 plant species (including common beans, soybeans, peas, chickpeas and lentils), of which 37 are indigenous Slovenian varieties. The last stop was at the Etri community, a leading group in the field of social entrepreneurship, whose aims are to build an inclusive society and change social norms. They are changing their practice in the fields of ecology, ergonomics and ethical economics. The story of the Etri community is about creating green jobs for individuals, often excluded from society, in collaboration with socially responsible companies. They intend to include more legumes in their meals and at the end of the visit they prepared a delicious legumes showcase lunch for the delegates. The whole event focused on the five links of the LAFC. 43 participants (21 females and 22 males) attended the workshop, of which six were TRUE members that acted as facilitators and four were invited government guest that discussed different aspects of LAFC related topics: regulatory organizations, education and knowledge transfer, financial and business mechanisms and public participation.

    AbstractWith the global economy not yet 10% circular, businesses are key stakeholders in designing new forms of resource use, especially large multinationals. However, compared with the wealth of studies on ‘born sustainable’ start‐ups, there is minimal case study or interview based research into how incumbent companies are approaching this transition. Focusing on plastics, we ask: how does one incumbent multinational company approach the circular economy transition? This paper presents a case study of the incumbent multinational chemical company Dow, a leading plastics manufacturer. Varied external stressors and drivers for the circular economy act upon a company (which also has its own imperatives), resulting in tentative steps towards circular economy. To date, these steps have tweaked the existing system rather than radically altering the business model. For companies, like for the entire global economy, this transition has only just begun. This paper identifies key drivers, enablers and barriers of the circular economy, none of which are fixed or immutable. Knowing which levers for change are available and effective could help policy makers to shift gear to enable quicker progress towards circularity. Overall, broad based support and engagement is needed to progress the circular economy, hence all stakeholders have roles to play in demanding and enacting circular practices.

    This paper estimates the vintage capital model of energy demand and examines operational and investment responses to energy prices at disaggregate level using data from five OECD manufacturing industries. Applying the model to less aggregate level data helps avoiding the distortions from exogenous structural shifts and measurement errors. The results confirm the previous findings that including capital stock vintages significantly improves the econometric model's goodness of fit. Estimated own-price elasticities of energy demand vary between 0.26 and 1.00 and are economically sound. Estimated own-price investment elasticities of energy efficiency of capital stock vary between 0.03 and 0.9. The investment response to energy prices thus varies significantly across manufacturing industries, being significant in some of them and negligible in other. The results of policy simulations for the U.K. petrochemical industry (the most energy-intensive industry in the sample) indicate that total (operational and investment) own-price elasticity of energy demand is close to one.
