Smallholder farming in Rwanda is a critical sector for agricultural productivity and rural livelihoods. The study employs ARIMA (AutoRegressive Integrated Moving Average) model to analyse time-series data from Rwanda's Ministry of Agriculture. The ARIMA(2,1,0)[0] model showed an adoption rate trend with a confidence interval around the mean forecast value of 95%. ARIMA models effectively predict smallholder farm technology adoption over time in Rwanda, offering insights for policy makers and farmers. Continue monitoring trends using ARIMA analysis for future intervention planning.
