The empowerment plan of local communities with the aim of promoting social capital makes an effort to improve the quality of life, poverty alleviation and job creation in poor communities and ultimately create sustainable development. This article has collected field information using the positivist paradigm and descriptive-analytical method using a questionnaire. The target population is 2549 members of the Ahmadi division Empowerment Fund in 30 target villages. This study was conducted in two time periods (before the establishment and operation of the funds (June 2020) and after the activities of the funds (June and July 2021)). Descriptive findings indicate that women, youth and literate people have been more involved in the establishment of funds. Analytical findings showed that the establishment of funds has been effective in increasing social capital indicators and has been able to strengthen social capital and ultimately sustainable rural development.
