Sustainable consumption trends are reshaping global food supply chains

A new study finds that consumers’ perceptions of sustainability are playing a decisive role in determining how much they are willing to pay for local food and whether they will continue buying it in the future.

The study, titled “Sustainable Value Perceptions and Local Food Demand: Implications for Regional Food Security and Supply Chain Sustainability,” published in Sustainability, introduces an integrated framework linking consumer value perceptions, market segmentation, willingness to pay, and purchase intention. It reveals that local food consumption is driven less by economic considerations and more by social trust and environmental awareness, signaling a structural shift in how food markets operate.

Sustainable value perceptions reshape consumer behavior in food markets

Modern consumers no longer make food purchasing decisions based solely on price or convenience. Instead, they increasingly factor in broader concerns such as environmental impact, ethical production, and transparency in supply chains. This shift has elevated local food systems as a key strategy for achieving sustainability across environmental, social, and economic dimensions.

Using survey data from 400 consumers in South Korea, the study measures sustainable value perceptions across three core dimensions: social, environmental, and economic. Social value reflects trust-related behaviors such as checking certifications and producer information. Environmental value captures awareness of issues like climate change and carbon emissions. Economic value relates to perceptions of structural challenges in agriculture and regional economies.

The findings show that these dimensions are not only distinct but also interact in shaping consumer decisions. Exploratory factor analysis confirms that consumer perceptions naturally cluster into these three categories, forming the basis for deeper segmentation of the market. This multidimensional structure allows researchers to move beyond fragmented analyses and examine how different value systems influence both willingness to pay and behavioral intentions.

The study reveals that consumers do not respond uniformly to sustainability cues. Instead, they can be grouped into four distinct segments based on their value perceptions, ranging from highly sustainability-oriented consumers to those with low social awareness but moderate environmental or economic concerns. This segmentation highlights the heterogeneity of consumer behavior and underscores the need for targeted strategies in promoting local food.

Higher trust and environmental awareness drive willingness to pay

Consumers with stronger social and environmental value perceptions are willing to pay more for local food products. The analysis shows that willingness to pay exceeds actual market prices across all examined products, including sweet potatoes, apples, and cherry tomatoes, indicating that consumers perceive local food as offering higher value than its current price suggests.

Differences across consumer segments are particularly evident for products such as apples and cherry tomatoes. Consumers in the high-value perception group consistently demonstrate higher willingness to pay compared to those with lower social awareness. This suggests that trust and transparency, rather than purely functional attributes, play a central role in shaping how consumers assign monetary value to food.

The study also finds that while economic value perception is recognized by consumers, it does not significantly influence their willingness to pay. This challenges traditional economic assumptions that price sensitivity is the primary driver of purchasing decisions. Instead, it indicates that consumers are willing to pay premiums for food products that align with their ethical and environmental values.

The research notes that the overall effect size of value-based segmentation on willingness to pay is moderate. This suggests that while sustainable value perceptions are important, other factors such as product characteristics, availability, and personal preferences also contribute to consumer decision-making.

The findings reinforce the idea that local food markets operate within a value-based framework, where trust in producers, confidence in product quality, and alignment with sustainability goals are key determinants of consumer behavior.

Purchase experience and environmental values shape future demand

The study examines how sustainable value perceptions influence future purchase intention. The results show that environmental and social value perceptions are strong predictors of whether consumers intend to continue purchasing local food, while economic value perception has no statistically significant effect.

Environmental awareness emerges as a particularly powerful driver. Consumers who perceive climate-related risks and environmental challenges as serious are significantly more likely to express future purchase intention. This indicates that environmental concerns are not only shaping attitudes but also translating into concrete behavioral commitments.

Social value perception also plays an important role, though to a slightly lesser extent. Consumers who prioritize transparency, certification, and trust in food production are more likely to maintain or increase their consumption of local food. This highlights the importance of relational factors in food markets, where trust between producers and consumers influences long-term purchasing behavior.

One of the strongest predictors is prior purchase experience. Consumers who have previously bought local food are significantly more likely to do so again, with the analysis showing a substantial increase in the likelihood of future purchase intention among this group. This finding underscores the importance of experiential factors in reinforcing consumer behavior.

The data further show that a majority of consumers with prior experience intend to either maintain or increase their level of local food consumption. This suggests that once consumers engage with local food systems, they are likely to develop lasting preferences that support continued demand.

Implications for food policy and sustainable supply chains

According to the study, strategies focused solely on price competitiveness are unlikely to be effective in driving local food consumption. Value-based approaches that emphasize trust, transparency, and environmental responsibility are critical. Providing clear information about production processes, certifications, and environmental impact can strengthen consumer confidence and increase willingness to pay.

The role of experience is equally important. Creating opportunities for consumers to engage directly with local food systems, such as farmers’ markets or community-supported agriculture programs, can reinforce positive perceptions and encourage repeat purchases. These interactions help build trust and reduce uncertainty, making consumers more likely to adopt sustainable consumption patterns.

The study also points to the need for targeted communication strategies that address different consumer segments. For example, consumers with high environmental awareness may respond more strongly to messaging about climate impact, while those with lower social awareness may require more emphasis on trust and transparency.

From a supply chain perspective, the findings suggest that local food systems can enhance resilience by aligning production and consumption more closely. By shortening supply chains and strengthening relationships between producers and consumers, local food markets can reduce vulnerabilities associated with globalized food systems.

The research also acknowledges that challenges remain. The gap between consumer willingness to pay and actual purchasing behavior indicates that barriers such as accessibility, availability, and convenience still need to be addressed. Additionally, the limited influence of economic value perception suggests that broader structural issues in agriculture may not directly translate into consumer action.
