ABSTRACT This study used a descriptive-analytical method to assess how vulnerable farmers in Fars Province's rural regions near the Tashk and Bakhtegan lakes are to the effects of climate change. For this purpose, 17 villages around Tashk and Bakhtegan lakes with 2511 households, who are engaged in agricultural activities, were investigated. To achieve the research goals, a broad range of indexes were determined with the dimensions of exposure, sensitivity, and adaptive capacity to climate change according to the Climate Vulnerability Index (CVI) and were evaluated in the field studies. According to the results, 52.93% of communities were highly vulnerable to climate change. On the other hand, only 23.52% of farmers had very low vulnerability, and 23.52% had moderate vulnerability. The local farmers were aware of the climate change in the studied region with an average of 4.56. Given that more than half of the villagers are highly vulnerable to climate change, the government and relevant institutions need to increase their resilience to vulnerability. Increasing vulnerability requires careful measurement and monitoring of all related variables, increasing adaptation to the generalization of insurance, access to facilities, and reducing climatic sensitivities by increasing livelihood diversification, reducing unemployment, and using drought-resistant plants.
