The current study aims to examine the symmetric and asymmetric effects of climate change (CC) on rice productivity (RP) in Malaysia. Autoregressive-Distributed Lag (ARDL) Non-linear Autoregressive Distributed (NARDL) models were employed this study. Time series data from 1980 2019 collected World Bank Department Statistics, estimated results are also validated using Fully Modified Ordinary Least Squares (FMOLS), Dynamic (DOLS), Canonical Cointegration Regression (CCR). findings ARDL show that rainfall cultivated area have significant advantageous output. NARDL-bound test outcomes display has an asymmetrical long-run impact productivity. Climate had varying degrees positive negative impacts Positive changes temperature a substantial destructive RP. At same time, variations production Malaysian agriculture sector. Changes areas, both negative, long-term optimistic Additionally, we discovered only affects output directions. policymakers must understand CC RP agricultural policies will promote sustainable development food security.
