The US has grown far more cucumbers than the Japanese have, but their consumption has been falling for decades.
But researchers from the University of California, Irvine are trying to change that, by studying how cucumbers have changed over the past 30 years.
The study, published in the journal Trends in Ecology and Evolution, looks at the changing habits of cucumbers across the US and Japan.
They found that the number of plants on Japanese farms has declined by more than 40% in the past 40 years.
What has been the change?
Cucumbers are the world’s favourite crop, so much so that people have grown them for centuries.
Their leaves, berries and seeds are used for everything from making soup to flavouring bread.
But over the last 30 years, there has been a dramatic drop in cucumber production in Japan.
It’s been a big change, but it isn’t entirely clear why.
“Cucumber production has been declining at a rate that is roughly twice that of the UK, which is the country with the highest per capita consumption of cucumber,” lead researcher Prof Tim Wilson told New Scientist.
“The reasons for this are not fully understood, but one possibility is that it is due to an increase in pesticides, as well as climate change.
The researchers also found that cucumbers were growing less in places where people lived in urban areas, and in the US, as their land is now being turned into soybean fields. “
It’s possible that they’re also getting more water from irrigation.”

How did the cucumbers change?
Wilson and his colleagues analysed data from the Agricultural Marketing Service (AMS), a US agency that collects plant data and is the primary source of plant-based data for agriculture.
They looked at how the number and types of plants grew on the farms, as compared with the previous year.
They used data from AMS’s Vegetation and Food Inventory (VFEI), a database of data about crops.
“We looked at the growth of different types of cucobas, or leaves, on the Japanese farms and found that overall the number [of leaves] increased by about 70 per cent,” Wilson said.
“We also found more cucobases growing in some locations than others.
This indicates that there were more plants on the [Japanese] farms that were not already there.”
This was an important finding because the amount of new growth on the crops was correlated with the use of pesticides, which have been associated with lower crop yields.
“Why did they change?”
Wilson said that while the researchers didn’t find that pesticides played a significant role, it does suggest that the changing seasons may be making the Japanese cucumbers more sensitive to climate change and pesticides.””
Cucumis nucifera, which means ‘cucumber’, is very high in carbon dioxide, and is an important greenhouse gas.”
Wilson said that while the researchers didn’t find that pesticides played a significant role, it does suggest that the changing seasons may be making the Japanese cucumbers more sensitive to climate change and pesticides.
“In terms of the impact of pesticides on cucumber yields, it is not clear,” Wilson told the BBC.
“However, the overall impact of herbicides on cucumbers has been shown to be associated with higher yield losses.”
The researchers used a statistical approach that accounted for all of the variables that affect crop growth, such as temperature, moisture, nutrient availability, soil type and soil temperature.
It found that pesticide use on Japanese cucumber farms had a significant impact on yields, which are the result of a combination of the increased uptake of pesticides and a reduction in nutrients.
“It may be that these differences in pesticide use could have a significant effect on crop yield.”
What do the researchers mean by a reduction of pesticides?
The researchers say that this is a result of the fact that Japanese people have become more sedentaried over the years.
That is, they’re using fewer fruits, vegetables and grains.
The researchers suggest that this reduction may be due to a decline in the use and availability of pesticides in recent decades, and an increase of herbicide use.
“Our study found that although there were declines in herbicide and pesticide use, there was a significant increase in soybean production, which was associated with a decrease in pesticide application,” Wilson added.
“However, we were not able to link this with the reduction in soybeans because the soybean crops we looked at were also grown on Japanese farmlands, and it’s possible they may be genetically different to Japanese soybean.”
If you look at other types of agricultural crops, the use rates for herbicides are usually higher in regions with higher agricultural productivity.
“What are the implications for the environment?
If you’re worried about climate change, you might want to take a look at cucumbers.
