Food as Climate Action : Rethinking What We Choose to Keep

We are producing more food than ever before, yet a significant portion of it is never eaten.

Globally, nearly one-third of all food produced is lost or wasted. This loss happens at multiple points during harvesting, in transit, on retail shelves, and in our own homes. The impact is not only environmental, but also economic and social. Resources are used to grow food that is never consumed, while at the same time, access to food remains uneven across many parts of the world.

Alongside this, food systems are under increasing pressure. Climate variability, rising input costs, and shifting consumer expectations are forcing both businesses and households to rethink how food is produced, distributed, and used.

What is becoming increasingly clear is this: food is not only nourishment . It is one of the most immediate and practical ways we participate in climate action.

 

 

A System Shaped by Everyday Decisions

When we think about climate action, we often think in terms of large-scale interventions- energy transitions, policy reform, or industrial change. But the food system is shaped just as powerfully by everyday decisions.

These decisions happen continuously:

• in homes, when we choose what to buy, cook, store, and discard
• in retail environments, when products are selected, displayed, and replenished
• in food service and manufacturing, when ingredients are sourced, used, and managed

Individually, these decisions may seem small. Collectively, they determine how efficiently , or how wastefully, food moves through the system.

For example, when food is purchased with a short window of use and not fully consumed, it contributes to waste. When businesses overstock perishable products without sufficient flexibility, it results in shrinkage. When supply chains rely heavily on formats that require constant replenishment, they increase pressure on logistics, storage, and cost.

In this way, food waste is not a single event. It is the outcome of many small decisions, repeated at scale.

 

The Role of Fresh … and the Need for Balance

Fresh food plays an essential role in how we eat. It connects us to seasonality, to nutrition in its most immediate form, and to the experience of food itself. It is, and should remain, a central part of our diets and food systems.

At the same time, fresh food has natural limitations. It is perishable. It requires careful handling, storage, and timely use. It often has a narrow window between peak quality and spoilage. These limitations do not make fresh food less valuable, but they do require systems and behaviours that support its effective use. Where these systems fall short, waste becomes more likely.

What we are beginning to see globally is not a move away from fresh food, but a response to the limitations of relying on it alone. Rising levels of food waste, increasing pressure on supply chains, and growing demand for convenience and shelf stability are all pointing in the same direction: the need for a more balanced approach, one that combines freshness with formats that extend usability and reduce loss.

 

Extending Value Across the Life of Food

Preserved and shelf-stable foods are not new. Long before modern supply chains and refrigeration, societies relied on methods such as drying, fermenting, and storing to ensure that food could be used across time, distance, and season. These practices were not alternatives to fresh food, but part of a broader system that allowed food to be used more fully and more efficiently. Fresh food was consumed where possible, and preservation ensured that what could not be used immediately was not lost.

Over time, however, the way we have come to value food has shifted.

In many modern food systems, freshness has been elevated as the primary marker of quality, while preserved foods have often been viewed as secondary,  something to fall back on, rather than something to actively choose. What is now changing is not the practice of preservation itself, but how we understand its role. There is a growing recognition that preservation is not simply about extending shelf life. It is about enabling food to be used more effectively — reducing loss, improving access, and allowing ingredients to move more flexibly across different contexts. For consumers, this may mean choosing products that last longer and can be used over time without compromising on quality or nutrition. For businesses, it may mean rethinking product and ingredient choices — for example, incorporating dried vegetables alongside fresh options to improve shelf life, reduce waste, and create more consistent supply.

In this sense, preserved and shelf-stable foods are not a compromise on quality. They are a critical part of how more resilient, efficient, and sustainable food systems can be built.

 

An Approach Rooted in Experience

Across many African food traditions, this balance has long existed. Food was consumed fresh where possible, but it was also dried, stored, and preserved for later use. These practices were not driven by trend, but by necessity,  shaped by seasonality, availability, and a deep understanding of how to make the most of what was available. Nothing was incidental. Very little was wasted.

This approach reflects a broader philosophy: that food is not only something to be enjoyed in the moment, but something to be managed, extended, and used fully over time. Today, as global food systems begin to confront the realities of waste, resource constraints, and sustainability, these principles are becoming increasingly relevant.

 

From Consumption to Stewardship

If food is climate action, then the role we each play begins to shift , from simply consuming food, to stewarding it. Stewardship requires a different mindset. It asks us (as consumers and as businesses) to consider:

• how we make the most of what we have
• how we reduce what is lost along the way
• how we design systems and habits that support better use of food

For consumers, this may be as simple as planning better, storing food more effectively, or choosing products that offer greater flexibility.

For businesses, it may involve more structural decisions , around sourcing, product mix, inventory management, and how different formats are used together to optimise both availability and efficiency.

In both cases, the shift is the same: from immediacy to intentionality; from abundance to efficiency; from waste to value.

 

Where We Sit in This Conversation

At Oya Foods, this perspective shapes how we think about food. Through our work, we extend the usability of ingredients and create formats that allow food to move more flexibly across different contexts, from everyday meals to retail shelves and food manufacturing.

But more importantly, we see ourselves as part of a broader shift: one that is not about choosing between fresh and preserved, but about using both more thoughtfully. It is a shift that invites us to rethink not only how food is preserved, but also what we choose to use, stock, and build into our daily habits and supply systems.

Looking Ahead

The future of food will not be defined by a single format or approach. It will be shaped by how well we balance:

• freshness and longevity
• convenience and care
• consumption and responsibility

And in many ways, the most important shift may be this:
not only asking what we eat, but how well we use what we have;  how intentionally it is chosen, how efficiently it is used, and how much of it ultimately reaches the plate.
