Para rubber feedstock production potential was explored in Hat Yai district. The study focused on the respondent&rsquo:s socioeconomic status, feedstock production potential, and mapped the relevant actors along the supply chain. Structured questionnaires were administered to 117 respondents chosen through random and purposeful sampling. The descriptive statistics, linear regression models, feedstock potential model, and Simpson&rsquo:s diversity index were used to analyze the data. The findings showed average ages of 54.4 and 48.4 for farmers and processors respectively, with above 40% literacy. Seventy-six percent of the plantations&rsquo: land belongs to the respondents with corresponding average yields of 9.5 tons/yr and 1082.5 logs for latex and parawood as the main products. Farmers and processors had a mean annual para rubber income of USD 6341.35 and 2.55 million USD, respectively. The analysis revealed a significant relationship between plantation size and feedstock supply: the theoretical feedstock potential is 831,630.91 tons and is highly diverse (Simpson&rsquo:s diversity index of 0.75), indicative of high potential for sustainable production and consumption. The study highlights that low latex prices alone cannot account for the decline in rubber feedstock yield, due to the high cost of new land, the inability of farmers to expand plantations, and four interlinked feedstock supply lines existing in the study area.
