Human-induced climate change is considered a threat to communities and the natural system, in particular, agriculture, forestry, economy, health, and well-being. Explicitly, extreme weather events namely flood and long dry season, are great concerns for Indonesia and the region. The purpose of this study is to detect rainfall and temperature trends in the Sub-district of Dramaga for the past thirty years. Dramaga has a huge number of populations relying on rain-fed agriculture, to feed themselves and support food security. Monthly rainfall and temperature data were obtained from the Dramaga Climatology Station of Meteorology, Climatology, and Geophysics Agency from the period 1990-2019. A Mann-Kendall statistical test has been run to detect the statistical significance of time series in comparison with the linear model. The findings indicated no significant trends in the seasonal and annual rainfall in the past thirty years, whereas, annual mean and maximum temperature are rising significantly. Further, the annual minimum temperature does not show a statistically significant increase. Climate events owing to the rainfall variation and Temperature rise threaten smallholder farmers. Results of the study might help decision-makers for climate-smart agricultural projects development at the community level. As to be able, to access environmentally sustainable self-sufficient agriculture.
