VIETNAM NATIONAL UNIVERSITY, HANOI VIETNAM JAPAN UNIVERSITY VU KIM DUYEN FACTORS AFFECTING TO STUDENTS’ BEHAVIORS ON GHGs EMISSION MITIGATION: CASE STUDY IN HANOI AND IBARAKI MASTER'S THESIS VIETNAM NATIONAL UNIVERSITY, HANOI VIETNAM JAPAN UNIVERSITY VU KIM DUYEN FACTORS AFFECTING TO STUDENTS’ BEHAVIORS ON GHGs EMISSION MITIGATION: CASE STUDY IN HANOI AND IBARAKI MAJOR: CLIMATE CHANGE AND DEVELOPMENT CODE: 8900201.02QTD RESEARCH SUPERVISOR Prof Ito Tetsuji Dr Takeuchi Ryo Hanoi, 2020 PLEDGE I assure that this thesis is the results of my own research and has not been published The use of other research’s result and other documents must comply with regulations The citations and references to documents, books, research papers, and websites must be in the lists of references of the thesis AUTHOR OF THE THESIS VU KIM DUYEN i ACKNOWLEDGMENTS I would like to thank JICA, Vietnam Japan University and Ibaraki University and MCCD program Moreover I appreciated my suppervisor professor Ito Tetsuji, Dr.Ryo Takeuchi and all professors, all staffs at Ibaraki University and ICAS who helped me alot and took care me everyday They gave me advices and a chance to experience to be more mature I had data both for my thesis topic and my life I have accumulated a lot of knowledge, skills, and opportunities to develop and change myself ever since I became a graduate student of MCCD First of all, it is the fundamental and in-depth knowledge about climate change and policies, climate change adaptation, and mitigation models that is extremely useful scientific knowledge which professors and the MCCD program offered me I have a background in psychology and had a period of time working directly with vulnerable groups in Vietnam I used to be very vague about the field of climate change But today, after two years of studying and practicing, I have been able to confidently explain to everyone about the impacts of climate change on ecosystems and human life, and at the same time, I can accompany vulnerable groups in climate change adaptation and mitigation efforts Specifically, in October 2019, with the support from lecturers, MCCD students and the online community raised money to plant 10,400 woody plants (Melaleuca and Erythrophleum fordii) in Nghi Xuan District, Ha Tinh Province This activity is the foundation for future afforestation and sustainable livelihood development projects In addition, the study program of MCCD also gave me a lot of opportunities to learn and connect with Vietnamese and Japanese professors, experts, which helps me gain more perspectives on professional science and policy so that my future path can be more clearly defined Thanks to the advice and support from experts of MCCD, 2020 is my pivotal year for the goal of establishing a social-business enterprise with the orientation of consulting and designing sustainable livelihood models Sustainable development (ecological forest gardens, mangrove development, etc.) to support people in climate vulnerable areas to have sustainable livelihoods adaptable ii to climate change, and to contribute to the development of zero-emission livelihoods towards climate change mitigation Moreover, the research results of my thesis have created the fundamental axioms that help me develop future in-depth studies to build models that promote behavior and attract students - intellectual and energetic young people to participate in climate change adaptation and mitigation projects in Vietnam Firstly, I can absolutely expect a team full of intellect, enthusiasm and energy to accompany on the projects of the social enterprise that I am cherishing Here, students will be the ones who speak their voices to the government, advocate with local authorities and also spread the fire, and stand side by side with Vietnamese farmers and fishermen who are currently participating in emission-free sustainable livelihood models This is a completely feasible scenario that personally, with all my passion, enthusiasm, and efforts, and the knowledge and skills accumulated after two years of working with MCCD, I am determined enough to realize this scenario Finally, thanks to the research shared by the professors, the valuable resources from the study program, and the opportunities to participate in international conferences on climate change, I realized that the practice of ecological lifestyle is one of the positive and effective contributions to the goal of reducing GHG emissions Therefore, since October 2019, I have chosen a vegan macrobiotic lifestyle with a diet of no meat, fish, no animal protein It's also the thought of being responsible to contribute even the smallest efforts to control the global climate crisis that has formed my habit of teaching my children to recycle, separate waste and make organic detergent from composted soapnuts and organic waste by themselves I understand that what I is very small and has not contributed much However, that is all the value and spirit that I accumulated after two years of studying and practicing at MCCD as well as the time of studying diligently the resources for my thesis I believe that it is better to something than doing nothing And I would like to once again express my gratitude to Vietnam Japan University, Ibaraki University, the MCCD program and all the professors, lecturers and experts who have created values for me iii and inspired me to continue my passion for implementing climate change mitigation projects in the future - a future starting with MCCD iv TABLES OF CONTENTS PLEDGE i ACKNOWLEDGMENTS ii CHAPTER INTRODUCTION 1.1 Problem statement 1.2 Research question .5 1.3 Hypothesis 1.5 Research objectives 1.6 Scope of the research 1.7 Expected results 1.8 Literature review 1.8.1 The effort of the world 1.8.2 The effort of Vietnam 11 1.8.3 Studies related to the issue of factors that impact students' climate change mitigation behaviors .15 CHAPTER THEORIES AND METHODOLOGIES 20 2.1 Theoretical basis .20 2.1.1 The theory of foundations .20 2.1.2 The concept and structure of behavior 25 2.1.3 Concepts and psychological characteristics of students 27 2.1.4 Climate change mitigation behavior of students .32 2.1.5 The theoretical framework 32 2.2 Methodological approach .32 2.2.1 Methods .34 2.2.1.1 Exploratory Factor Analysis 34 2.2.2.2 Social Psychology Experimental 35 2.2.2.3 In-depth interview method 36 2.2.2.4 Method of experts .36 2.2.2.5 Group work 37 CHAPTER FINDING AND DISCUSSION 39 3.1 Case study in Hanoi 39 3.1.1 Students’ awareness of global warming and climate change 39 3.1.2 Students' behavior of reducing global warming 47 3.1.3 Analyzing the factors that influence students' GHGs emission reductions 53 3.2 Case study in Ibaraki 60 3.2.1 The factors affecting Ibraki student’s behaviors .60 3.2.2 Analysis of expert opinions .69 CHAPTER CONCLUSION AND RECOMMENDATION 76 4.1 Conclusion 76 v 4.2 Recommendations 84 REFERENCES 87 APPENDIX 89 vi LIST OF TABLES Table 2.1 Study sample size ……………………………………………………… 34 Table 2.2 group work activities ………………………………………………… 38 Table 3.1 Students' perceptions of climate change and global warming 41 Table 3.2 Data encrypt …………………………………………………………… 49 Table 3.3 Correlation between student readiness and frequency of GHGs mitigation behavior ……………………………………………………………………………50 Table 3.4 Variables of non-correlated variable values ……………………………52 Table 3.5 Describe the 36 observed variables that apply to the EFA model …… 53 Table 3.6 Factor matrix with Varimax rotation method ………………………… 58 vii LIST OF FIGURES Figure 1.1 Global investment trends and capacity of wind and solar energy …… 10 Figure 1.2 GHGs emission trends based on some sectors in Vietnam period 19942005 ……………………………………………………………………………… 13 Figure 2.1 Paradigm of Theory of Reasoned Action (TRA) ………… 20 Figure 2.2 Paradigm of Theory of Reasoned Action (TRA) – new model ……… 21 Figure 2.3 The factors affecting students behaviors model (by author) ………… 25 Figure 2.4 Framework of research (by author) ………………………………… 32 Figure 2.5 Process of approaching sequential mixture ………………………… 33 Figure 2.6 The Main Methods of research ……………………………………… 34 Figure 3.1 Average point of observed variables ………………………………… 40 Figure 3.2 Students' perception of global warming -
