The Effects of Climate Change on Food Security and Economic Growth in BRICS-T Countries: A Panel ARDL Approach

This article aims to analyze the effects of climate change on food security and economic growth. In this context, the BRICS-T countries Brazil, China, Russia, India, South Africa, and Turkey are examined using autoregressive distributed lag (ARDL) estimates for long-run and short-run cointegration for the period 1991–2023. Climate change is measured by CO₂ emissions and precipitation. The findings indicate that increased rainfall improves food production in India, China, and Turkey, whereas for Brazil, South Africa, and Russia, precipitation has a negative impact on food production. However, the results in the short run demonstrate that CO₂ emissions have an insignificant effect on food production in BRICS-T. The long-run coefficient estimates indicate that precipitation has a negative effect on GDP. Whereas, CO₂ emissions are found to have a positive and statistically significant impact on GDP.
