The Impact of Science-Based Sufficiency Economy Immunity on Farmers’ Practice of the Three Core Principles and Two Conditions in Chiang Rai Province

Background and Aim: Integrating the Sufficiency Economy Philosophy (SEP) with the Sustainable Livelihoods Framework (SLF) is essential for promoting sustainable development among Thai farmers. This study investigated how five Science-Based Sufficiency Economy Immunity dimensions, Mind, Economy and Society, Learning Culture, Natural Resources and Environment, and Technology, influence farmers’ practice of Three Core Principles (Moderation, Rationality, and Immunity) and Two Conditions (Morality and Knowledge) in Chiang Rai Province. Materials and Methods: A mixed-methods approach was employed, using qualitative data from documentary analysis, group discussions, and interviews, and quantitative data from structured questionnaires. The five-dimensional Science-Based Sufficiency Economy Immunity framework was used to assess internal factors affecting implementation. Results: Findings revealed high levels of Science-Based Sufficiency Economy Immunity application, particularly in the Mind and Natural Resources and Environment dimensions. Regression analysis identified the Mind dimension as the strongest predictor (β = .572, p < .001), with the model explaining 49.7% of the variance in Science-Based Sufficiency Economy Immunity practice (Adjusted R² = .497). Conclusion: Results highlight the importance of mental development, environmental stewardship, and lifelong learning. Policy recommendations emphasize community empowerment, participatory management, and capacity building. This integrated Science-Based Sufficiency Economy Immunity –SLF approach supports the SDGs by enhancing quality of life, income security, and sustainable self-reliance.
