How the Climate Crisis Is Intensifying World Hunger
Driven by global warming and extreme weather, the climate crisis is worsening food insecurity and putting millions at risk of hunger worldwide.
Global hunger has reached alarming new heights, driven by the escalating impacts of the climate crisis. While several complex and interlocking factors contribute to food insecurity, a rapidly warming planet is now recognized as one of the critical forces exacerbating hunger in every region of the world. This article explores how climate change is fueling a surge in food shortages, what it means for vulnerable communities, and what can be done to address this urgent humanitarian challenge.
Understanding the Scale of Global Hunger
- 733 million people faced hunger in 2023, or about one in eleven globally, and one in five in Africa.
- More than 2 billion people experienced moderate to severe food insecurity in 2023.
- Since 2015, global hunger has increased dramatically, reversing years of progress.
- The world is currently off track to achieve the United Nations Sustainable Development Goal (SDG) 2: Zero Hunger by 2030.
Behind these figures are millions of families facing daily struggle, malnourished children whose growth and learning are impaired, and entire communities forced to migrate in search of food and security.
The Climate Crisis: A Driver of Hunger
Several interrelated factors are contributing to the current global hunger crisis, but climate change stands out as a rapidly increasing threat. It interacts with conflict, economic shocks, and inequalities, amplifying their impact. The key ways in which climate change drives food insecurity include:
- Extreme Weather Events: Rising global temperatures fuel more frequent and intense floods, droughts, cyclones, and wildfires.
- Disrupted Food Production: Climate change reduces yields by damaging crops and limiting farmers’ ability to grow food.
- Destroyed Infrastructure: Roads, bridges, and local food supply chains are damaged, cutting communities off from food markets and aid.
- Forced Migration: People are displaced when their land is no longer habitable or productive, often leading to increased hunger.
Extreme Weather: Increasing Frequency and Intensity
Driven by the rise in average temperatures, the world is experiencing a five-fold increase in extreme weather events over the past 50 years. The 2010s were the hottest decade on record, and July 2023 set a new monthly temperature record. As disasters become more common, their effects grow more devastating:
- Droughts: Longer, harsher droughts devastate crops and livestock.
- Floods and Cyclones: Infrastructure, farmland, and homes are destroyed, disrupting local economies and food distribution.
- Wildfires: Escalating wildfires reduce agricultural productivity and affect water resources.
More than 1.7 billion people have been affected by climate-related disasters over the past decade, many left hungry and displaced.
How Climate Disasters Damage Food Supply Chains
- Extreme conditions destroy transport infrastructure, leaving remote areas without access to food.
- Floods and landslides can permanently disrupt supply chains, making relief and aid distribution nearly impossible in some regions.
- In regions reliant on a single road or access point, the risks are especially high — when this lifeline is lost, entire villages can go hungry for extended periods.

The damage to food supply chains reverberates globally as local shortages drive up prices and limit exports.
Regional Impacts: Who Is Most Vulnerable?
The effects of the climate crisis on hunger are not felt equally across the globe — the poorest communities suffer the most, despite contributing the least to global emissions.
- Africa: 20.4% of the population faced hunger in 2023; half of all people projected to be chronically undernourished in 2030 will live here.
- Asia: 8.1% of people face hunger; although percentage-wise stable, Asia is home to more than half of the world’s hungry.
- Latin America: Some progress, with 6.2% facing hunger, but climate shocks still pose substantial risks.
- Other Regions: Hunger increased in Western Asia, the Caribbean, and most African subregions from 2022 to 2023.
Countries Facing the Worst Hunger Crises
According to the World Food Programme, ten countries currently suffer the most from hunger, driven by conflict and climate extremes:
- Afghanistan
- Democratic Republic of the Congo
- Yemen
- Haiti
- Sudan
- Niger
- Nigeria
- South Sudan
- Somalia
- Burkina Faso
These countries account for tens of millions living on the brink of famine, with children and mothers suffering most severely.
The Human Costs: Lives Disrupted by Hunger
- Stunted Growth: Children exposed to prolonged food insecurity suffer irreversible damage to their physical and cognitive development.
- Intergenerational Cycles: Malnourished mothers give birth to malnourished babies, perpetuating hunger across generations.
- Diseases and Reduced Productivity: Undernourished individuals are more prone to illness and often unable to work to improve their livelihoods.
- Migration: Hunger and climate disasters often force entire communities to leave their homes in search of food and safety.
Extreme hunger and malnutrition remain a barrier to sustainable development, limiting human potential and trapping communities in poverty.
Main Drivers Behind the Current Food Crisis
While climate change has become a clear and growing factor, it is part of a complex system of causes:
- Conflict: The leading driver of hunger globally, war destroys infrastructure, displaces people, and disrupts markets.
- Climate Change: Increasingly severe weather and climate shocks ruin crops, threaten livelihoods, and undermine food systems.
- Economic Shocks: Rising food and fuel costs force millions to choose between eating and other essentials.
- Pandemics: COVID-19 accelerated the rise in global hunger, increasing food insecurity around the world.
- Inequality and Civil Insecurity: Marginalized populations are most exposed to risk and have few resources to recover.
Table: Key Factors Driving World Hunger
| Factor | Impact on Food Security |
|---|---|
| Climate Crisis | Destroys crops, livestock, and food systems; triggers displacement and migration |
| Conflict | Damages infrastructure, causes displacement, disrupts markets and aid |
| Economic Shocks | Inflates food prices, reduces access to vital nutrition, worsens poverty |
| Pandemic | Reduces income, increases food insecurity, disrupts supply chains |
| Inequality | Prevents vulnerable populations from accessing food and resources |
Why Should We Care?
Food security is linked to every aspect of human development. The consequences of unchecked hunger include:
- Slower economic growth
- Higher rates of disease and mortality
- Reduced educational attainment and gender equality
- Increased instability and migration
Solving hunger is not just a moral imperative — it is essential for sustainable global progress, prosperity, and peace.
Building Resilience: Solutions to the Hunger Crisis
While fixing the root causes of climate change may take decades, immediate action can help communities become more resilient and secure food supply chains. Responses include:
- Social Protection: Expanding support systems to shield the vulnerable from food shortages.
- Transforming Food Systems: Reforming agricultural practices to be sustainable and climate-resilient.
- Investment in Agriculture: Increasing funding to boost productivity, create jobs, and strengthen community resilience.
- Emergency Food Assistance: Rapidly delivering aid to regions in crisis while addressing long-term drivers.
- International Cooperation: Coordinated global responses, including efforts to cut emissions and invest in adaptation.
Actions at the Community Level
- Promoting climate-smart agriculture
- Investing in local food storage and transport infrastructure
- Developing early warning systems for disasters
- Empowering women and marginalized groups in food production

Conclusion: Turning Urgency into Action
The climate crisis has set the stage for a global food challenge unlike any in recent history. Rising temperatures and extreme events are violently disrupting systems and lives, making world hunger harder to solve. Yet with coordinated investments in resilient agriculture, social protections, and climate adaptation, there is potential to radically improve food security for millions. Achieving zero hunger by 2030 will require urgent, bold action at every level — but creating a future free from hunger is possible.
