From the field to the kitchen

Have you ever wondered why olive oil has become more expensive, why some vegetables are harder to find, or why menus increasingly feature seasonal and regional ingredients? The answer often lies far beyond the kitchen. Climate change is already affecting how food is produced, transported and prepared. For future chefs, bakers, restaurant managers and catering professionals, understanding these changes is becoming an essential part of their profession.

Every meal begins long before ingredients arrive in a restaurant, hotel or school kitchen. Farmers depend on stable weather, but climate change is making weather patterns more unpredictable. Heatwaves, droughts, storms and floods are becoming more frequent, reducing harvests, lowering food quality and disrupting food supplies. As a result, hospitality businesses face changing ingredient availability and fluctuating prices.

Heat and drought: When water becomes scarce

One of the greatest challenges is increasing water stress, which occurs when demand for water exceeds the available supply or when poor water quality limits its use. Hotter summers and lower rainfall are placing growing pressure on freshwater resources across Europe.

Agriculture is one of the largest users of freshwater. During the summer months, irrigation accounts for around 40% of Europe’s freshwater withdrawals. During droughts, farmers may struggle to grow crops such as lettuce, tomatoes, potatoes, berries, grapes and olives. Water shortages reduce harvests and can also affect the size and quality of produce, making ingredients more expensive or harder to source.

Too much water can also be a problem

Heavy rainfall and flooding can be just as damaging. Floods may destroy crops, wash away fertile soil and delay planting or harvesting. Wet conditions also increase plant diseases, while damaged roads and transport networks can interrupt deliveries of fresh ingredients.

For hospitality businesses, this means menus and purchasing decisions need to become more flexible.

Extreme weather affects prices

When harvests are poor, supply decreases while demand often remains the same. This pushes up the prices of products such as vegetables, fruit, olive oil, cocoa and coffee, and some ingredients may become temporarily unavailable.

For professional kitchens, this creates new challenges. Chefs increasingly need to adapt recipes, review purchasing decisions and make greater use of seasonal ingredients.

Global supply chains are becoming more vulnerable

Modern hospitality relies on international food supply chains. Coffee may come from South America, rice from Asia, spices from India and cocoa from West Africa. Climate change affects many of these regions at the same time, reducing production and disrupting transport.

This shows how closely local restaurants are connected to global environmental changes.

What does this mean for future hospitality professionals?

Chefs and catering professionals can actively support more sustainable food systems. Their choices matter because, according to the IPCC (Intergovernmental Panel on Climate Change), agriculture, forestry and other land use account for about 22–24% of global greenhouse gas emissions.

Working with seasonal and regional ingredients helps reduce transport impacts and improves resilience when supply chains are disrupted. Reducing food waste also saves the land, water, energy and labour needed to produce food.

Flexibility is becoming an essential professional skill. When one ingredient is unavailable, chefs can often substitute another seasonal product. Offering more plant-rich dishes can also reduce environmental impacts, as many plant-based foods require fewer natural resources than animal products.

Sustainability starts during vocational training

Vocational schools play an important role in preparing students for these challenges. Students can explore how climate change affects agriculture, compare seasonal menus, analyse supply chains and develop recipes using local ingredients.

Practical activities—such as redesigning a menu after a poor harvest or reducing food waste in a training kitchen—help students connect sustainability with everyday professional practice.

Looking ahead

Climate change will continue to shape agriculture and food production. Weather extremes, water scarcity and changing growing conditions will influence what food is available, when it can be harvested and how much it costs.

For future hospitality professionals, sustainability is becoming a core professional skill. The kitchen of the future is more than a place where meals are prepared – it is where culinary skills, sustainability and climate awareness come together. Every informed choice can help protect natural resources and build a more resilient food system, one meal at a time.
