The pervasive use of single-use plastics (SUP) has emerged as a critical environmental concern globally. In the heart of Southeast Asia, Thailand grapples with significant plastic waste challenges, making it imperative to understand and foster behaviours that reduce plastic consumption. This study sheds light on this pressing issue by exploring the psychosocial factors influencing SUP reduction among Thai university students. The study is pivotal for its insights into the dynamic process of behaviour change within an academic setting, offering valuable lessons for environmental policy and educational strategies.

Context and Methodology

The study focuses on university students in Thailand, a demographic that is both influential and representative of future societal leaders. The research utilizes the Theory of Planned Behaviour (TPB) and the Transtheoretical Model (TTM) to assess students’ intentions and actions towards reducing SUP consumption. This integrated model approach allows for a nuanced analysis of the stages of behaviour change—from pre-contemplation to maintenance—and the impact of attitudes, perceived behavioural control, and subjective norms across these stages. The methodology encompasses a combination of confirmatory factor analysis (CFA) and structural equation modelling (SEM) to validate the theoretical framework and examine the causal relationships among the variables. The research was conducted with a sample of 317 undergraduate students from five major universities in Thailand. These students were chosen due to their informed perspectives on the environmental impacts of SUPs, as evidenced by preliminary findings from a pilot study.

Key Findings

The results reveal a complex landscape of behavioural intentions shaped by different psychosocial factors at various stages of the behaviour change process:

1. Attitudes: Positive attitudes towards reducing SUP were significant predictors of behavioural intention only in the contemplation phase, suggesting that while students recognize the benefits of reducing plastic use, this recognition does not always translate into action.

2. Perceived Behavioural Control: This was a consistent predictor across all stages, indicating that students’ beliefs in their ability to reduce plastic consumption significantly influence their behaviour. This factor had a stronger effect in the action phase, underscoring the role of self-efficacy in facilitating behaviour change.

3. Subjective Norms: These were particularly influential in the pre-contemplation phase, highlighting the importance of social influences and norms in shaping initial attitudes toward behaviour change.

The study also introduces the concept of “behavioural spillover,” suggesting that engaging in SUP reduction behaviours might encourage other pro-environmental actions, thereby enhancing overall environmental engagement among students.

Policy Implications and Recommendations

The findings have profound implications for policymakers and educational institutions aiming to promote environmental sustainability:

· Targeted Educational Campaigns: Universities should tailor their sustainability education and campaigns to align with the specific phases of behaviour change, emphasizing the development.

· Social Norms and Peer Influence: Initiatives that harness the power of social influence, such as student-led advocacy groups or peer-to-peer education programs, could be particularly effective in the initial stages of behaviour change.

· Behavioural Spillover: Educational programs should also consider the potential for behavioural spillover, encouraging students to adopt a broader range of sustainable practices beyond just SUP reduction.

This research not only contributes to our understanding of environmental behaviour among young adults in a university setting but also offers a blueprint for how educational institutions worldwide can foster a more sustainable future.

On 8^th February 2024 we had a fascinating internal seminar talk by Dr Oluseye Oludoye on Pro-Environmental Behaviour Towards Sustainable Food Systems.

Oluseye introduced us to his research including pesticide, cocoa flavours, and plastic chemistry. The talk introduced the team to how people consider use of pesticide, but more importantly the impact of usage on the environment, including soil health. The talk encouraged the group to think about economics, biodiversity and climate change, a really thought provoking and insightful lunchtime session.

On November 29, 2023, Environmental Research Society led by the MSc students hosted Dr Oluseye Oludoye. He presented on the topic titled “Sustainable Agriculture and Waste Management: A Path Towards Environmental Stewardship”. This presentation delves into the pivotal role of these interconnected practices in shaping environmental sustainability. In the pursuit of a sustainable and resilient future, the intersection of agriculture and waste management emerges as a critical nexus.

In the intricate dance of sustainable agriculture and waste management, individual behaviours become catalysts for change. He stated that our journey begins with understanding the symbiotic relationship between responsible agricultural practices and effective waste management.

Connecting the Dots: Sustainable agriculture is not merely a buzzword but a commitment to cultivating the land while preserving its essence. For instance, Dr Oluseye Oludoye’s research on pesticide safety behaviours among cocoa farmers underscores the significance of responsible agricultural practices (https://doi.org/10.1080/1059924X.2022.2148147). By embracing sustainable farming methods, we protect ecosystems, foster biodiversity, and ensure the health of our soil.

Agricultural Sustainability: The adoption of sustainable agricultural practices contributes to the reduction of greenhouse gas emissions. Through practices like agroecology, we not only grow our food but also nurture a climate-friendly environment. He noted that our choices in agriculture have a direct impact on mitigating climate change, ensuring a healthier planet for generations to come.

Reducing Carbon Footprint: Beyond mitigating climate change, sustainable agriculture plays a pivotal role in preserving biodiversity. By choosing sustainable practices, we become stewards of the planet, maintaining the delicate balance of ecosystems and ensuring the well-being of diverse plant and animal species.

Preserving Biodiversity: He encouraged the Environmental Research Society to serve as a beacon of change, empowering its members to drive transformative action. Armed with insights from our research at Earth and Environment Group, each member was encouraged to be an advocate for sustainable agriculture in their local communities. For example, by actively engaging in initiatives that promote responsible waste management, we sow the seeds of a greener future.

Empowering Change: He stated that the collective impact of individual choices cannot be overstated. Our call to action extends beyond personal behaviours to highlight the transformative power of united efforts. Through collaborative projects, advocacy initiatives, and global awareness campaigns, he emphasizes that every action, no matter how small, contributes to the global tapestry of sustainability.

Emphasizing Collective Impact: In concluding this exploration of sustainable agriculture and waste management, he reminded the society members that the choices we make today echo into the future. By embracing these practices, we cultivate not only a bountiful harvest but also a legacy of environmental stewardship for generations to reap. Let us, as members of the Environmental Research Society, be the custodians of change, nurturing a greener, more sustainable Earth for all. Together, we embark on a path towards environmental stewardship, one that honors the planet we call home.

When is this amazing talk on?

It’s on 22 November, 1.15pm-2pm in the MIMA Study Centre – a rare chance to hear MIMA’s curators talk about the process of narrating an environment, the River Tees, and engaging with communities to do so.

Great if you and any of your students would like to come. Booking helps us – booking is at www.tees.ac.uk/events
