Uncertain factors cause to generate any unstable processes along supply chains, and then also reduce supply chain performance. Some sources of uncertainty of agri-food supply chains are distinct from general supply chains such as variable harvest and production yields, and a huge impact of climate conditions. Thus, it is crucial to deeply understand which distinct perceived uncertain factors in agri-food supply chain that can affect to its management and its performance in order to allow agribusiness to deal with these effects properly. The purpose of this study is to discuss the perceived environmental uncertainties in the context of rice supply chain in Thailand. The literature analysis found that supply, demand, process, planning and control, competitors’ actions, government policy and climate uncertainty might have been perceived by Thai rice supply chain. The research method is a survey method with mail-out questionnaires to rice millers and rice exporters in Thailand. Descriptive statistics is employed to review which uncertain factors are greatly perceived within the rice supply chain. Major findings show that planning and control, competitor’s action, government policy and climate uncertainty are mainly perceived along the supply chain. This confirms that as planning and control is highly uncertain, information technology is not implemented in Thai rice industry. Lack of appropriate IT tools can not deal effectively with environmental uncertainties. Additional, there is high competition in both rice domestic and international market leading to high unpredictable competitors’ action. Government policies of developing countries are turbulent, and climate uncertainty is continually obvious in Thai rice industry.
