Summary
Climate change severely impacts global food security, with research highlighting data integration challenges and a bias towards developed nations. Future studies must focus on developing countries and employ advanced models.
Area of Science:
- Environmental Science
- Agricultural Science
- Climate Science
Background:
- Global food security is increasingly threatened by climate change, rising CO2 levels, population growth, and land degradation.
- Existing research on climate change impacts on food security has limitations in data integration and geographical representation.
Purpose of the Study:
- To review and analyze research trends on climate change and global food security from 1988-2018.
- To identify research gaps and propose future research directions.
Main Methods:
- Bibliometric analysis of 31 years of research data from the ISI Web of Science platform.
- Cluster analysis and research hotspot analysis using VosViewer software.
Main Results:
- Identified two major drawbacks in current research: fragmented field data and underrepresentation of developing countries.
- Highlighted the need for improved data integration methods and a greater focus on African and Asian nations.
Conclusions:
- Emphasized the necessity of developing modified mathematical models for data processing and integration.
- Called for global collaboration among governments and organizations to address climate change impacts on food security.

01:16What is Climate?
19.4K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:50Global Climate Change
25.1K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

01:57Adaptations that Reduce Water Loss
26.8K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

01:50Threats to Biodiversity
23.6K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
