Foods Most at Risk from Climate Change and What We Can Do
Essential foods like coffee, chocolate, and shellfish face a precarious future as climate change impacts global agriculture and food security.
Foods Most at Risk from Climate Change—and What We Can Do
Across the globe, climate change is affecting the way food is grown, harvested, and enjoyed. The tastes and traditions we treasure—coffee in the morning, chocolate in desserts, or peaches ripened in the summer heat—are all under threat as rising temperatures, shifting rainfall patterns, and extreme weather events reshape agriculture. But while the future of our favorite foods hangs in the balance, there are strategies and innovations that may help preserve them for future generations.
How Climate Change Threatens Global Food Staples
Farming and food production are deeply connected to the environment. As greenhouse gas emissions rise, so do temperatures and the unpredictability of weather patterns around the world. The result is a suite of challenges for farms, ranches, fisheries, and all the foods we rely on.
- Increased Drought: Many regions are experiencing historic droughts, dramatically reducing yields of crops like cocoa and coffee.
- Intense Heat Waves: Excessive heat can stress plants and reduce productivity, impacting everything from wheat to peaches.
- Extreme Weather: Hurricanes, floods, and unexpected freezes can destroy entire harvests in days.
- Ocean Changes: Warmer and more acidic oceans are putting shellfish, fish, and seaweed farming at risk.
Most Vulnerable Foods
Certain foods are particularly sensitive to climatic shifts. Below are staple items whose future remains uncertain in a warming world:
- Coffee: Grown in tropical mountain regions, coffee is highly sensitive to both heat and rainfall disturbances. Farmers have begun moving coffee crops to higher elevations, but there is only so much available land. Models predict that suitable land for coffee could shrink by half by 2050.
- Chocolate (Cocoa): The cocoa plant requires very specific growing conditions—hot, humid, but not too wet. Droughts, changing rainfall, and plant diseases are already reducing yields, and leading chocolate-producing regions may become unsuitable in just a few decades.
- Stone Fruits (Peaches, Apricots, Cherries): Unpredictable late frosts, early springs, and sweltering summers have left states like Georgia with catastrophic peach losses, and many other temperate fruits are at risk.
- Wine Grapes: Viticulture is extremely sensitive to microclimates. Traditional wine regions are seeing earlier harvests, increased disease, and some varietals may become unviable, while entirely new regions further north or south become possible future hubs.
- Shellfish (Oysters, Mussels, Clams): As ocean waters warm and acidify, shellfish have difficulty forming shells, and entire fisheries like snow crab and West Coast salmon have collapsed in recent years due to population crashes.
Why Can’t We Just Move Production?
A common suggestion is that crops can simply 3migrate 4 north or south to cooler climates. While this shift is occurring slowly, it comes with major caveats:
- Limited Suitable Land: There is not always appropriate soil, infrastructure, or know-how in these new areas.
- Economic and Cultural Loss: Generations of farmers often cannot pick up and leave family lands, and regional identities are tied to food production (e.g., Georgia peaches).
- Increased Pests and Diseases: As temperatures warm, new regions may face unfamiliar pests and pathogens.
Case Studies: The Changing Face of Iconic Foods
- Peaches in Georgia: Georgia, nicknamed the “Peach State,” lost up to 90% of its peach crop in recent years due to erratic weather. Unseasonably warm winters, followed by freezing temperatures, disrupt peach buds and yields. While other states further north might start growing peaches, the unique flavor profile and branding may not follow.
- Coffee in Latin America and Africa: In major coffee-producing countries, farmers are already migrating crops up mountainsides in search of cooler temperatures, but land is limited and pests migrate too. Without significant action, coffee could become a much rarer commodity by 2050.
- Chocolate from West Africa: Over 70% of cocoa is produced in West Africa. Chronic droughts and temperature spikes are causing declines in output and even spikes in chocolate prices. Disease and deforestation compound the issue as the rainforest is cut for new farmland.
- Oysters and Shellfish in the Pacific Northwest: Ocean acidification makes it difficult for young shellfish to build shells, drastically reducing populations and jeopardizing both wild fisheries and aquaculture.

How Animal Agriculture Exacerbates Climate Risks
Many scientists argue that the way we produce food, especially animal agriculture, is accelerating these climate threats. Livestock production is responsible for significant emissions of methane and nitrous oxide, powerful greenhouse gases. Additionally, land is cleared (often tropical forests) to provide pasture or grow animal feed crops, releasing enormous amounts of carbon and threatening biodiversity.
- Greenhouse Gas Emissions: Livestock account for more than 14% of global emissions, greater than all forms of transportation combined.
- Deforestation: Forests that absorb CO2 are destroyed to graze animals or plant soy for livestock feed.
- Water Stress: Animal agriculture is a major consumer of freshwater resources, often diverting water away from food crops for direct human consumption.
The Case for Plant-Based Diets
Transitioning to plant-based diets is cited by experts as one of the most effective means to both reduce emissions and build resilient food systems. Research finds that if more land is used to grow food for people, rather than animal feed, more people could be fed with fewer resources, lowering pressure on both climate and land.
Plant-based foods generally require less land, use less water, and produce fewer greenhouse gases than animal products. This dietary shift could be crucial in averting long-term food shortages and environmental degradation.
Technologies, Policies & Solutions: Hope for the Future
While the situation is dire, some advances offer reason for optimism. Innovation in agriculture and food systems may help buffer the blow of a changing planet.
- Climate-Resilient Crops: Breeding and genetic modification are leading to new varieties that can withstand drought, heat, and novel pests.
- Sustainable Aquaculture: Some shellfish and seaweed farmers are experimenting with methods to buffer acidification and produce food with a small carbon footprint.
- Policy Incentives: Governments and international bodies are beginning to reward climate-smart farming, soil conservation, and forest protection through subsidies and regulations.
- Best-Available-Food Principles: Institutions are being urged to prioritize food purchases with the lowest environmental footprint—typically plant-sourced—helping shift demand.
What Individuals Can Do
- Eat More Plants: Opt for plant-based meals to minimize your dietary carbon impact.
- Reduce Food Waste: Plan meals and store food properly to avoid needless waste, which adds emissions from both production and decomposition.
- Support Sustainable Brands: Buy from food producers and companies committed to sustainability.
- Advocate for Change: Raise your voice for climate policies and practices that prioritize food security and environmental recovery.

Frequently Asked Questions (FAQs)
Q: Can technology really save our favorite foods from climate change?
A: While technology can help develop more resilient crops and innovative farming practices, it cannot fully offset rapid climatic changes without large-scale emissions reductions and sustainable land management.
Q: Will plant-based diets actually make a big difference?
A: Yes, shifting the global diet away from animal agriculture to plant-based foods significantly reduces greenhouse gas emissions, land use, and water consumption, making food systems more resilient.
Q: Is it too late to save foods like coffee and chocolate?
A: Not necessarily. With aggressive climate action, plant breeding innovation, and dietary shifts, it is possible to stabilize conditions for these crops. However, without intervention, large-scale losses are likely.
Q: Why are oceans crucial for our food supply?
A: Oceans supply key nutrients through fish and shellfish and help regulate the planet’s climate. However, rising temperatures and acidification disrupt these resources, threatening marine-based foods.
