Currently, a combination of natural and human factors has led to the lack of cost-effective production, resulting in the downturn of traditional animal husbandry (DTLH) in rural regions. This research aims to investigate the factors contributing to the DTLH in indigenous communities in northwestern Iran. The statistical population consisted of pastoralists residing in the villages of Namin-Ardabil, Iran. The research method employed was descriptive-analytical, and a questionnaire was used as the data collection tool. The sample size was determined by selecting approximately 5–10% of households in each village, preferably the household head. Friedman's test was utilized to prioritize the most significant factors influencing DTLH. The findings reveals that the most crucial economic criteria contributing to the DTLH were “the high cost of providing inputs and fodder required for livestock (mean rank = 11.12),” “more economic opportunities and access to well-paying employment opportunities in the city (mean rank = 8.99)”, and “low profit from livestock farming in the rangeland (mean rank = 10.60)”. Moreover, the most important social criteria were “uncertainty regarding the future well-being of children and the social and economic situation in the village (mean rank = 14.12)”, “motivation for academic and career development in urban areas (mean rank = 14.10)”, and “access to specialized and professional training opportunities in cities (mean rank = 13.80)”. Furthermore, the most crucial ecological criteria impacting the DTLH were “drought” (mean ran = 7.96)” and “non-implementation of range management plans and grazing permits” (mean rank = 6.07)”. In general, the results indicated that the ecological criteria had the highest impact on the DTLH, followed by social and economic criteria, with values of 41.1%, 34.6%, and 24.29%, respectively. Overall, understanding the challenges faced by traditional livestock husbandry and identifying the factors contributing to its decline is crucial for developing effective strategies to support and sustain this industry in rural areas.
