In a groundbreaking study published by scientists from the University of Göttingen in Germany and the University of Edinburgh in the United Kingdom, a surprising discovery has emerged: out of 186 countries analyzed, only one nation is fully self-sufficient in food production. That country is Guyana, a small South American nation with a population of less than one million.
This finding underscores the global vulnerability of food systems and raises important questions about the sustainability of agricultural production and international trade dependencies.

Guyana: The World's Only Food-Self-Sufficient Nation
Researchers evaluated the domestic production capabilities of seven key food groups across 186 countries. These food categories include:
- Cereals
- Vegetables
- Fruits
- Meat
- Dairy
- Legumes
- Oils and fats
Guyana was the only country found to produce enough food in all seven categories to meet the needs of its population without relying on imports. This level of food sovereignty is unmatched globally, even by agricultural powerhouses.
Close Contenders: China and Vietnam
Only two other countries come close to matching Guyana’s feat. China and Vietnam are capable of meeting their domestic needs in six out of seven food groups, showcasing strong agricultural infrastructure but still falling short of full self-sufficiency.
Global Food Imbalance
The study paints a sobering picture of global food insecurity. Key takeaways include:
- Only 1 in 7 countries can produce sufficient food in at least five categories.
- Over one-third of countries are only self-sufficient in one or two food groups.
- Six nations — Afghanistan, United Arab Emirates, Iraq, Macao, Qatar, and Yemen — cannot produce enough food in any of the seven essential categories.
This means that millions of people globally depend heavily on food imports for their daily sustenance.
Economic Unions Are Not Immune
Even economic and regional blocs demonstrate weaknesses in food self-sufficiency:
- The Gulf Cooperation Council (GCC) is only self-sufficient in meat.
- West African and Caribbean unions manage to produce adequate food in just two categories.
- No international union is fully self-sufficient in vegetables, a key component of a healthy diet.
The Risks of Trade Dependency
While international trade currently acts as a buffer against food shortages, the study emphasizes the risks associated with over-reliance on a single trading partner. Many countries import more than 50% of their food from just one country, making them highly vulnerable to:
- Political instability
- Climate events
- Supply chain disruptions
- Conflicts or sanctions
Such scenarios can lead to widespread food insecurity, especially in regions with limited domestic production.
The Call for Stronger Global Cooperation
To combat these risks and ensure long-term food sustainability, researchers recommend:
- Strengthening international trade networks, diversifying import sources.
- Investing in agricultural technology and education, particularly in food-insecure countries.
- Encouraging local food production initiatives to reduce dependence on imports.
- Building resilient supply chains that can withstand global disruptions.
The authors highlight that food security is a shared responsibility. It not only affects public health but also impacts economic stability, social cohesion, and national security.
Implications for Global Policy
The study’s findings suggest that current global systems are ill-equipped to handle long-term food challenges such as:
- Climate change
- Water scarcity
- Land degradation
- Urbanization
Policy shifts are needed to create resilient agricultural systems. Countries must rethink how they balance local production with global trade to mitigate risks and safeguard future generations.
Why This Matters Now More Than Ever
In an era marked by pandemics, wars, and climate crises, food independence is increasingly being seen as strategic national infrastructure. Guyana’s example proves that self-sufficiency is possible, even for small nations, through smart agricultural policies and sustainable land use.
