A Tale of Two Trends: Analyzing Hunger Over Decades
To answer the question, "Has world hunger increased since 1970?", one must consider both the long-term trend and more recent shifts. The narrative is not a straightforward one of consistent decline or rise but rather a complex interplay of progress and reversal driven by multiple global factors.
The Long-Term Trajectory: Progress from 1970 to the Mid-2010s
From 1970 to the mid-2010s, the prevalence of undernourishment in developing countries saw a significant decline. This progress was fueled by factors such as the Green Revolution's agricultural advancements, global economic development lifting people out of poverty, and improvements in health and sanitation. International cooperation and aid also played a role in addressing food crises. By the mid-2010s, this trend pointed towards the potential achievement of the 'Zero Hunger' Sustainable Development Goal.
The Alarming Reversal: Setbacks in Recent Years
Around 2015, the positive trend reversed, and the number of people facing hunger began to rise. This shift was driven by a combination of global shocks. For instance, estimates indicate that around 733 million people were undernourished in 2023, an increase from 2019 levels.
Key factors behind this reversal include conflicts, which disrupt food systems in affected regions; climate change, which causes extreme weather events that damage agriculture; economic downturns and shocks, like the COVID-19 pandemic, which have increased food prices and reduced access to nutritious diets; and persistent inequalities that leave vulnerable communities more susceptible to food insecurity.
Comparison: Hunger Prevalence (1970s vs. 2020s)
| Metric | Late 1970s (Developing Countries) | Early 2020s (Global) |
|---|---|---|
| Prevalence of Undernourishment | ~37% of the population | ~8.2-9.2% of the population |
| Absolute Number of Undernourished | N/A (Population lower) | ~673-733 million (2023-2024 estimates) |
| Primary Drivers | Population growth, limited technology, poverty | Conflict, climate change, economic shocks |
| Overall Trend | Generally declining | Reversed and rising since 2015 |
This table highlights that while the percentage of hungry people has decreased significantly since the 1970s, the absolute number has recently increased, particularly since the mid-2010s.
A Globalized Problem with Local Impacts
Hunger's impact varies geographically, with some regions making progress while others face rising rates. For example, hunger has increased in parts of Africa. The understanding of food insecurity has also broadened to include access to nutritious diets, not just calories. The issue of the dual burden of malnutrition (undernutrition alongside rising obesity) further complicates the global food picture.
Conclusion: More Than a Simple Answer
So, has world hunger increased since 1970? While the prevalence (percentage) has decreased significantly over five decades, the absolute number has risen since the mid-2010s. This reversal is driven by factors like conflict, climate change, and economic instability. A simple 'yes' or 'no' doesn't capture this complex reality and the recent worrying setbacks.

Key Factors and the Way Forward
Addressing world hunger requires tackling both immediate crises and underlying issues. Investing in sustainable agriculture, strengthening social safety nets, and resolving conflicts are crucial.
Actionable Insight: Increased investment in rural infrastructure and agricultural research is needed, especially as it has declined despite the growing crisis.
Challenges and Next Steps
- Address Climate Vulnerabilities: Implement agricultural adaptation strategies in climate-sensitive areas to protect crops.
- Prioritize Conflict Resolution: Increase efforts in preventing and resolving conflicts, a major cause of hunger.
- Ensure Equitable Access: Address economic and social inequalities that make marginalized groups more vulnerable to food insecurity.
A Call to Action
Ending hunger demands sustained political will, global cooperation, and investment in resilient food systems. While progress since 1970 shows improvement is possible, recent setbacks highlight the ongoing challenge.
- Promote Sustainable Food Systems: Encourage productive and sustainable agricultural practices that improve soil health.
- Reduce Food Waste: Tackle the issue of food loss and waste.
- Strengthen Social Safety Nets: Expand programs to help vulnerable populations access food during crises.
- Invest in Research and Technology: Support research for resilient crops and technologies, particularly in developing countries.
