Purpose The article investigates the impact of global climate change on agricultural output and Cereal production in BRICS countries from 1989 to 2022. Design/methodology/approach The author employs several econometric methods, like the second-generation unit root tests, Westerlund co-integration test, Pooled mean group (PMG), Dynamic fixed effect (DFE) and Mean group (MG) models, to evaluate the relationship between agricultural output, cereal production and climate change. Findings The results show that temperature has a long-run negative impact on agricultural output, and precipitation has a positive long-term impact on agricultural output. In addition to other factors, the moderating effect of renewable energy and ICT is positive and significant on agricultural output and cereal production. Research limitations/implications The period covered in the study is constrained by data availability, limiting the ability to assess longer-term trends. Originality/value The research adds to the current literature gap by investigating how climate change affects agricultural output and cereal production in BRICS countries and checks the interaction effect of variables, i.e. ICT and renewable energy, on agricultural production and cereal production.
