Abstract
Global climatic conditions are expected to become more variable in the future, which will have far-reaching impacts on food production. In Asia, many of these impacts have been measured, but a comprehensive analysis of the effects of climate change on food production at the regional scale is limited. In this study, two key issues were addressed. First, we estimated the actual trends in temperature and precipitation across 12 Asian countries in Southern, South-Eastern, Western, and Eastern Asia between 1970 and 2018 and examined their implications on food production. Second, we deployed robust estimation techniques and examined how climatic conditions influence food production across Asian sub-regions. The results show that annual temperature across Asian regions trends positively. However, a cross-country analysis reveals varied trends in annual rainfall. The regional results indicate that temperature significantly induces food production in all regions except South-Eastern Asia, where the effect is negligible. Rainfall promotes food production in Southern, South-Eastern, and Western Asia but is not favourable to food production in Eastern Asia. The findings also show that the impacts of climatic variables on food production differ significantly from country to country. Our results are robust and suggest that substantial investments in agricultural extension, research programmes, and improved irrigation infrastructure are critical to enhancing food production and security in Asia.
