Climate change is bringing drastic changes to the food availability, accesses ability, quality, and stability of the food system in the World. This study investigates the impacts of climate change as a precursor on food security over Punjab regions, Pakistan, from 1979–2020. The bound test cointegration approach is applied with auto-regressive distributed lag (ARDL) to investigate the linear impact of climate variables on food production. This study found that Wheat cultivated area, total irrigated area, total un-irrigated area, and total area sown has a positive and significant impact on food production in all regions of Punjab Pakistan. However, while average, the maximum and minimum temperature is negatively and significantly associated with food production in all regions of Punjab except northern Punjab, where maximum temperature affects positively food production Punjab. Rainfall positively affects food production in central and western Punjab while negatively affecting food production in northern and southern Punjab. Furthermore, wind speed negatively affects food production in all regions of Punjab except northern Punjab.
