Abstract
BackgroundClimate change poses a threat to global food security. Assessing research activity on food security in the presence of climate change is important for policymakers and funding sponsors to make future decisions. The current study aimed to give an overview of research activity on food security in the context of food security.MethodologyA bibliometric methodology was implemented using the Scopus database for the period from 1980 to 2019. The search strategy utilized the title/abstract search of keywords related to food security and climate change with certain constraints. Bibliometric indicators, frequent author keywords, research themes, and international research collaboration were presented.ResultsThe search query retrieved 5960 documents. The last decade of the study period witnessed an increasing trend in both the number of publications and the number of cumulative citations. The top five author keywords were climate change, food security, drought, adaptation, agriculture, and water scarcity. Mapping the retrieved documents showed four general research themes: water security, crop yield, food availability, and health. The Sustainability journal ranked first in terms of productivity while documents published in the Global Change Biology journal received the highest number of citations per document. At the country level, the USA ranked first in terms of numbers, India ranked first in terms of research productivity per GDP/capita, and the UK ranked first in terms of the number of citations per document. France and the Netherlands had the highest percentage of documents with international authors while India and China had the least. At the regional level, the European region had the highest contribution and the Eastern Mediterranean region had the least contribution. Half of the top-cited documents in the field were review articles and appeared in prestigious journals. At the institutional level, the active list included three Chinese and two American institutions.ConclusionFood security under the umbrella of climate change is an emerging global challenge. Research on new technologies to mitigate the impact of climate change on food security is a top priority. Research contribution and collaboration from world regions with limited resources should be encouraged.

Summary
Climate change poses a threat to global food security. Assessing research activity on food security in the presence of climate change is important for policymakers and funding sponsors to make future decisions. Sweileh Agric & Food Secur (2020) 9:11 is associated with greenhouse gases such as carbon dioxide, methane, chlorofluorocarbons and nitrous oxide [2]. The IPCC report published on 2014 demonstrated that, on average, global mean crop yields of rice, maize and wheat are projected to decrease between 3 and 10% per degree of warming above historical levels. Climate change will contribute to global food insecurity by reducing crop yield, increasing expenses due to drought, and increasing food prices and the number of people with poor nutrition [4, 5]
