A bibliometric review on the inter-connection between climate change and rice farming

Rice is an important cereal and a staple food in many countries in the world. Climate change is a significant challenge that affects paddy production and threatens food security. However, research and development in this area continue to work to ensure the supply of rice fulfils the demands of the population. The study aims to analyse the transformation of international research power in trends in climate change that threaten food security (rice) worldwide. This study evaluates existing publications, especially research works from the period 1970 to 2020. The Web of Science database and the VOSviewer software were used together to generate a systematic analysis. A total of 1181 publications on climate change and paddy production were identified, written by 2249 authors from 56 countries. The highest number of publications was from China with 240 publications with 4609 citations, followed by India, with 225 publications and 2070 citations. Yield and adaptation are the most frequently used keywords that reflect this field's current significant research direction. Besides that, developing countries have received greater attention from researchers to focus on science, agriculture, climatology, and agriculture engineering as their domains. Therefore, socio-economic aspects should also be highlighted to raise awareness of the dangers of climate change and improve the farmers' economy by increasing paddy production. Attention was given by all countries globally, especially by researchers and stakeholders who need to plan holistic policies and strategies to encourage sustainable rice production and at the same time reduce the impact of climate change worldwide.
