How climate change is altering the look, taste and nutrition content of fruits and vegetables

The economic cost of food waste in Australia is staggering. Itโ€™s estimatedย $36.6 billion is lost to the economy every year. Much of our fresh produce never even makes it to stores,ย rejectedย at the farm gate due to cosmetic reasons, such as its appearance, size or ripeness.

Weโ€™ve known about this problem for a long time, which has given rise to the โ€œuglyโ€ food movement. Once-rejected produce has beenย rebrandedย as โ€œwonkyโ€ in the UK, โ€œingloriousโ€ in France, โ€œnaturally imperfectโ€ in Canada or an โ€œodd bunchโ€ in Australia.

While the existence of these campaigns is commendable, thereโ€™s another major marketing challenge if we want to reduce food waste – acceptance of climate-affected produce.

Broadly speaking, this refers to produce affected by extreme or moderate weather events. Droughts are an example of such climate events, predicted to becomeย more intense and frequentย as a result of global climate change.

Climate-affected produce resembles โ€œuglyโ€ food as it is often smaller, misshapen or has surface imperfections.

But in contrast to โ€œuglyโ€ food, the taste and texture of climate-affected produce can be quite different.

Under theย effects of drought, apples may become sweeter and more granular, chillies hotter and onions more pungent. In the case of mild or moderate droughts, such produce isย still edible.

Our recentย researchย points to some uncomfortable truths. Many consumers prefer to avoid climate-affected produce altogether. And when price is a factor, they wonโ€™t choose it without a discount.

But our research also offers suggestions on how purchases of such produce could be encouraged โ€“ including marketing messages that highlight the โ€œresilienceโ€ of climate-affected produce.

Our research

We carried out two discrete choice experiments with consumers who buy fresh fruit and vegetables. One sample was drawn from among Australian students, the other from members of the wider Australian population.

Participants were shown eight different apple options simulating a shopping environment, which were described with a range of different attributes including firmness, sweetness, appearance and size.

The apples were also labelled with a price tag and information on whether they were sold at a supermarket or farmersโ€™ market. All climate-affected apples were presented with a โ€œresilienceโ€ message: โ€œresilient apple โ€“ survived the droughtโ€.

We sought to examine how produceโ€™s โ€œorganolepticโ€ properties โ€“ the way it impacts our different senses โ€“ as well as levels of empathy toward the farmers impact consumersโ€™ willingness to choose climate-affected produce, and how much theyโ€™d pay for it.

A preference for perfect

We found when an appleโ€™s firmness, size and aesthetics were important and empathy towards farmers was low, consumers tended to avoid climate-affected produce. They instead chose unaffected alternatives at higher prices (no such effect was observed for sweetness).

This finding might not be surprising, but itโ€™s still cause for concern. If farmers cannot repurpose climate-affected produce into spreads, jams, smoothies or animal feed, it canโ€™t enter supply chains and may end up as waste.

Previous campaigns for โ€œuglyโ€ fruit and vegetables may not offer much help with this problem, either. These campaigns emphasise the unaffected taste and texture of the produce. Marketing climate-affected produce needs a different approach.

Otherwise, we expect a discount

When price was important to consumers, they chose climate-affected produce, regardless of their levels of empathy toward farmers. But they were only willing to pay discounted prices for it.

That might seem like a more positive outcome. But consumer expectations that climate-affected produce will always be discounted may disadvantage farmers with lower profit margins and diminish its value as a still-usable resource.

The power of โ€œresilienceโ€ messaging

Importantly, we found when the โ€œresilienceโ€ message resonated with consumers, they were more inclined to consider climate-affected aples. This was true even when their empathy towards farmers was low.

This suggests that when empathy fails, leveraging marketing messages that highlight โ€œresilienceโ€ could be another avenue worth exploring.

Our research team is now exploring what types of โ€œresilienceโ€ messages can encourage purchases of climate-affected produce.

Australians have beenย conditionedย for many years to expect only aesthetically pleasing fruit and vegetables.

Givenย extreme weather eventsย are unlikely to become less frequent in the future, climate-affected produce is likely here to stay. If we want consumers to embrace it, we need to have uncomfortable conversations around its different taste and texture, and rethink what weโ€™re willing to accept.
