What Will Cause Food Shortages in 2023 and Beyond?[Updated for 2026]

People worldwide have undoubtedly heard a lot about recent food shortages. Many individuals have experienced these disruptions firsthand through empty grocery shelves and startling receipt totals. Multiple factors combined to disrupt food supplies in recent years and continue to make everyday staples more challenging to obtain.

Supply Chain Disruptions and Trade Bottlenecks

While earlier factory closures and emergency lockdowns post-COVID-19 faded into the past, global distribution networks still experience frequent strains. Today, international transport logjams and trade restrictions create inventory shortages across entire continents.

Critical Maritime Passages Face Major Delays

Modern grocery distribution relies heavily on open maritime corridors and international trade routes. In 2024, two vital shipping passages experienced severe disruptions at the same time. Ongoing security conflicts in the southern Red Sea forced major container carriers to divert around the southern tip of Africa. 

The United Nations Conference on Trade and Development revealed that trade volume passing through the Suez Canal dropped by more than 40% in early 2024. That detour added ten to 14 days of travel time between Europe and Asia while increasing marine fuel expenses and ocean shipping rates.

Simultaneously, an extreme dry spell at Gatun Lake forced the Panama Canal Authority to slash daily boat crossings by 30% in late 2023 and early 2024. The International Food Policy Research Institute documented how these transit restrictions delayed bulk vessels carrying American corn and soybeans bound for overseas buyers. Such travel delays ran up transport bills and left grain waiting at crowded export docks.

National Export Restrictions Create Sudden Gaps

Government policy choices also cause unexpected inventory shortages in local grocery aisles. Several large agricultural producers enacted export limits to protect domestic food reserves. 

India placed a strict ban on non-basmati white rice exports in July 2023 and maintained the policy through September 2024. Because India supplied about 40% of the international rice market, the export halt pushed global rice prices to a 15-year high according to the World Bank. Shoppers throughout West Africa and Southeast Asia absorbed steep price increases for their primary daily grain.

Similar restrictions emerged across Southeast Asia and South America for sugar, wheat, poultry and cooking oil. When one government restricts exports to keep food at home, nearby communities face immediate supply gaps. Importing merchants must spend weeks securing alternative providers at higher spot prices.

Food Insecurity and Rising Grocery Costs in the United States

The United States also contends with persistent food access challenges. Even with well-stocked distribution warehouses, cumulative grocery costs remained high after years of broad-based inflation. Research from Feeding America indicates that around 48 million people in the U.S. struggled with food insecurity in 2023 once emergency relief programs ended.

Budget pressures force millions of families to change their weekly meal plans and purchase cheaper processed foods. Local distribution hiccups or unexpected regional storms leave supermarket shelves bare and spark temporary inventory gaps for staples like eggs, dairy items, beef and fresh produce.

Climate Change and Extreme Weather

Scientists warn that climate change and weather extremes continue to disrupt vital crop production. Persistent droughts dry out agricultural lands and reduce seasonal harvests. 

Regardless of the weather, topsoil health affects crop yields. Estimates suggest healthy topsoil helps cultivate 95% of the food humans eat. Decades of heavy tillage and erosion continue to strip organic matter from working farmland and leave crops vulnerable to dry spells.

Extreme heat also takes a heavy toll on crop productivity. Global meteorological agencies confirmed 2024 as the hottest year on record. Scorching temperatures and erratic rainfall hit cocoa orchards across Côte d’Ivoire and Ghana — regions that produce around 70% of the world’s supply. Such conditions pushed global cocoa prices above $10,000 per metric ton. Back-to-back droughts across Spain, Italy, Portugal and Greece reduced Mediterranean olive oil production by roughly a third and drove retail prices to historic highs, causing ripples through the market.

Some positive developments have occurred alongside these weather challenges. Researchers at the University of Sheffield developed genetically modified rice strains to increase salt tolerance, allowing coastal farmers to cultivate crops despite rising sea levels. Agricultural scientists also advance CRISPR-edited crops to help staple plants survive intense heat and prolonged drought.

Food Waste and Landfill Methane

People also advocate for waste reduction to curb agricultural pressure and reduce environmental harm. A study by the United Nations Environment Program revealed that human communities discard more than one billion meals worldwide every day. Strikingly, households generate 60% of global food waste, while food service businesses and retail grocery stores account for the rest.

Discarded food rotting inside airless municipal landfills creates large volumes of methane. This gas traps 86 times as much heat as carbon dioxide over a 20-year span. The escaping gas warms the atmosphere and intensifies the very weather extremes that damage crops. Cities frequently invest in municipal composting and organic diversion programs to keep edible groceries out of landfills.

War in Ukraine and Geopolitical Conflict

Fears of food shortages grew considerably following the outbreak of warfare in Ukraine. Christopher A. Ripple, who teaches an American food governance course at the University of Virginia, emphasized that people have valid reasons to worry. Ripple explained that the global food system relies on a relatively small number of large food commodity exporters, with Ukraine and Russia standing out as two of the most significant.

Ripple noted that fighting would keep harvested crops from reaching international markets and prevent farmers from planting future crops. Trade sanctions and export bans on fertilizers and agricultural inputs also created prolonged uncertainty for global farm yields.

Regional Difficulties and Agricultural Repercussions

Supermarkets across the United Kingdom and Europe felt the effects of these tensions as edible oil supplies tightened. Russia and Ukraine collectively produce about 60% of the world’s sunflower oil. Higher prices for alternatives like rapeseed and palm oil compounded grocery costs, since sunflower oil is a core ingredient in hundreds of consumer foods.

Multiple Middle Eastern and African nations also encountered steep food price hikes. Egypt and Turkey experienced severe disruptions to agricultural shipments, creating immediate price pressure on domestic bread supplies. 

While commercial carriers partially restored Black Sea cargo movements through an independent Ukrainian shipping channel in 2024, Ukrainian agriculture still confronts deep physical challenges. Unexploded ordnance contaminates millions of acres of fertile soil, while the destruction of irrigation dams cut off critical water networks to southern fields.

These prolonged pressures altered consumer habits across the continent. A study of consumers in 10 European countries found that 81% of respondents changed how they view and use food in the aftermath of the war in Ukraine, citing it as the main reason for rising food prices. Nearly the same portion, 55%, believed the conflict negatively affected overall food production.

Armed conflict continues to drive food insecurity across other fragile territories as well. The United Nations Global Report on Food Crises identified warfare as the leading cause of acute food insecurity. Clashes displaced farming families in Sudan and damaged cropland in the Middle East. When warfare halts agricultural production, nearby regions struggle to replace lost provisions.

Food Shortages and Practical Coping Tips for Families

It’s hard to predict how the issues mentioned here could affect the current year or beyond. However, the practical reality is that none of these issues will magically disappear in the short term.

With that in mind, suggestions can help you manage during the ongoing food shortages:

• Be flexible, and know each grocery trip may result in incomplete successes. Additionally, if the items families want are in demand, they may need to pay more for them.
• Donate to areas most affected by food shortages if possible. Many reputable charitable organizations allow one-off contributions or monthly donations.
• Try not to become too preoccupied with news reports. It’s good to be aware of possible food supply chain issues, but dwelling on them to the point that it harms mental health will not lead to a better outcome. Though times may be uncertain, it does the mind and body good to focus on the positives wherever possible.

Ongoing Work Is Vital

Food shortages caused by climate change will only improve with collective and dedicated efforts. In West Africa’s Sahel region and the Horn of Africa, severe weather continues to drive food insecurity for tens of millions of people. Alternating cycles of severe drought and flash floods destroy grazing lands and ruin consecutive planting seasons.

A 2024 FAO-WFP Hunger Hotspots report warned that acute food insecurity would worsen in 18 hunger hotspots from June to October 2024. The report identified conflict, economic shocks, weather extremes and climate variability as overlapping drivers of worsening hunger, including flood risks in parts of South Sudan, Somalia, Ethiopia, Chad, Mali, Nigeria and Sudan. It also emphasized early warning systems, anticipatory action and emergency response as essential tools for protecting livelihoods before food insecurity deteriorates further.

Building Everyday Food Security

Global logistics bottlenecks and unpredictable weather continue to disrupt supermarket supplies in 2026 and beyond. Consumers still maintain genuine control inside their own homes. Families protect their weekly grocery budgets through simple pantry audits and flexible meal plans. Supporting regional growers and curbing kitchen waste help turn unpredictable food cycles into lasting household security.
