Abstract: Climate change has brought enormous challenges to human lives, livelihoods, and the environment. Temperature increase, abnormal floods, and water pollution have negatively impacted on socioeconomic and agricultural systems in the Vietnamese Mekong delta. The aims of this study are to assess the readiness of traditional rice farming systems in the Vietnamese Mekong delta in adapting to climate change conditions and select traditional rice genetic materials for supporting breeding programs in the future. The research was conducted from April 2016 to December 2017 in the upper part of the Vietnamese Mekong delta, including An Giang, Kien Giang, and Long An provinces where the cultivation of traditional rice varieties or TRV thrive with the conditions brought by the climate change such as drought and salinity. Social research methods were used to assess farmers’ socioeconomic status, indigenous farming knowledge, and the alternative farming models in the context of climate change. Sampling seeds were also analyzed based on morphological and yield-related indicators. TRVs are distributed mainly in Kien Giang and Long An provinces and some mountainous areas of Tri Ton district in An Giang province. Yield varies from four to seven t/ha and these rice varieties are well adapted to unfavorable soil and adverse weather conditions such as drought, salinity, and alum toxicity. These rice varieties can tolerate submergence of
