Abstract: Abstract The South Asian region has faced multiple challenges in the last few decades. This region is susceptible to climate change due to the presence of both drought-prone and coastal areas. It also faces the problem of increasing food-insecurity due to the recent events of crop failure consequent to natural calamities. This study examines the nexus between agricultural production and food security amidst climate change for the South Asian nations from 2000 to 2019. From the empirical investigation, using Driscoll-Kraay and Panel-Corrected Standard Error estimators, we get robust results in the presence of cross-sectional dependence and heteroskedasticity. The simultaneous equation model using 3SLS is also used for the robustness check, considering the probable endogeneity issue in the model. The findings of the study reveal that agricultural production, fertilizer consumption, and land under cereal production play a substantial and positive role in determining food security in the South Asian nations. Furthermore, the varying rainfall patterns coupled with rising temperature, as well as the increasing level of CO2 emissions are found to impede food security in these nations. Additionally, non-climatic factors related to agriculture and land-use are also found to induce CO2 emissions, which is a major cause of climate change. Therefore, from a policy perspective, this study suggests that to ensure long-term food security in the South Asian nations, the government should implement effective policy measures, which include the decarbonization of the agricultural sector by encouraging the use of renewable energy sources and promoting climate-resilient agricultural practices.
