Climate Change Threatens Food Security and Public Health: Study Warns of Potential Impacts

Strategic Insights -

Researchers at Universiti Kebangsaan Malaysia's Faculty of Sciences and Technology have conducted a comprehensive bibliometric analysis to explore the complex interactions among public health, food security, and climate change. Through a thorough examination of research trends from 2007 to 2023, the study identified six primary research clusters, including climate change vulnerability and health adaptation, climate-resilient agriculture for sustainable food security, and epidemiological insights based on climate, dietary, and gender changes. The study highlights the need for interdisciplinary cooperation and stakeholder involvement in executing successful sustainability initiatives.

Key Takeaways:

  • The study identified six primary research clusters: climate change vulnerability and health adaptation, climate-resilient agriculture for sustainable food security, balancing nutrition and environmental footprint, epidemiological insights based on climate, dietary, and gender changes, aquaculture's role in global food systems and public health, and food insecurity-public health challenges.
  • Notable contributors to the research include Scarborough, P., and researchers from Universiti Kebangsaan Malaysia's Faculty of Sciences and Technology.
  • The study found that interdisciplinary cooperation and stakeholder involvement are essential for executing successful sustainability initiatives.
