There is a growing concern on the impacts of climate change and climate variability on water resources, agriculture, fisheries, and consequently livelihood of local people in Lower Songkhram River Basin of Thailand, where is a flood plain with freshwater swamp forests, marshlands, and small streams. Those things provide livelihoods for people living in this area. Thus, it is important to examine the people{u2019}s perceptions onclimate change and climate variability and its impact on their livelihood. In addition, this research will help the policy makers to scale up innovative adaptation measures by study the local people adaptation. As a result, the objectives of this study are to analyze the recent and future trend in hydro-climatic and water quality, to examine the level of people{u2019}s perception of climate change and climate variability at the household level, and study the people adaptation strategies against the climate change impacts on water availability and agriculture production. Climate data were analyzed through trend analysis. The trends have been calculated by Mann-Kendalltest and Sen{u2019}s slope. In part of precipitation indices, it shows significant trends in six indices from seven indices but different station in recent trend. Mostly, there are significant trends under RCP8.5 during 2055s. For RCP4.5, there are trends only in Sakon Nakhon province. In part of temperature indices, it shows significant trends in some indices in recent trend. For the future trend, mostly have significant trend under RCP8.5 during 2085s.Moreover, there are some trends lightly in another future periods.As agriculture is highly sensitive to climate or/and weather, the production processes are impacted by any type of changes in it. To understanding the rural farming community{u2019}s perception of climate change impacts on their socio-economic activities and environment, their adaptation at the household level and opinions on government mitigation measures. This study is based on both primary and secondary data collected via a survey of 25 households in three villages. The results show that people canperceivethe change in rainfall and temperature but they cannot perceivethe change in season.
