2022 has been a difficult year for European agriculture. 

We can start with the Russia/Ukraine conflict and how that has changed market conditions and supply chains of certain critical things, like fertilizers. Then, we can continue with the fact that these difficulties were followed by drought conditions. Figure 1 summarizes some of what has become visible across the market of European agricultural yields. 

  • Grain maize yield is expected to be down 8.6%.
  • Sunflower yield is expected to be down 5.5%.
  • Soybeans are expected to be down 9.6%.

Can Gene-Edited Crops Present a Solution?

There are European politicians expressing support for the use of genetic modification techniques in agriculture. Italian lawmakers are one such example, and the catalyst is that the recent heat waves and drought are leading to the demand for more resilient crops. If genetic modification is one path to provide for this type of mitigation, it’s possible it should receive all due consideration. Italy’s longest river recorded its lowest levels in the past 70 years over the summer season of 2022.2

One Genetically Modified Crop Is Grown in Europe

A certain bug-resistant strain of corn is the only genetically modified crop that has been grown within the European Union, based on the current highly restrictive rules. This is in stark contrast to the approach taken in the United States, where about 90% of the soybean and corn fields are genetically modified.3 Figure 2 illustrates the progression of a few different crops in the U.S.4 

  • Herbicide-tolerant soybeans saw the fastest ramp-up in terms of adoption, followed by herbicide-tolerant cotton. Herbicide-tolerant corn had a slower ramp-up, but then a later acceleration to roughly the same ending level in 2020.  
  • Insect-resistant cotton and insect-resistant corn also saw significant uptakes. As of this writing, insect-resistant soybeans were not yet commercially available.

Importantly, there is a difference between genetic modification and gene editing.5

  • Genetic Modification: Genetic material from another organism is inserted into the DNA of a plant. Typically, this makes the plant resistant to insects or herbicides.
  • Gene Editing: This is a newer technique, and it involves editing or adjusting the genome of the organism, not bringing in material from a different organism.

It was thought that gene editing might avoid GMO regulations in Europe, but these hopes were dashed in 2018 when the European Court of Justice ruled that gene-edited crops should be subject to the same regulations as GMOs.6  

What Are the Most Desirable Outcomes? 

If it is determined that the avoidance of gene editing and GMOs is the most desirable outcome, that is one thing. Maybe the current policies in Europe meet this goal. However, globally we have many different goals. Lowering greenhouse gas emissions is certainly another goal that is widely discussed in Europe and across the planet. 

What if the wider adoption of genetically modified crops in Europe could reduce the equivalent of 7.5% of the total agricultural greenhouse gas emissions for the region? This is roughly equal to 33 million tons of carbon dioxide equivalents per year.7  

Maybe the most desired outcome is to increase yield, since this could lead to greater food security for a given region, and it could also increase supply relative to a baseline during a time of higher inflation. Agricultural commodities tend to see their prices move based on supply and demand expectations. Research so far indicates the potential for genetically engineered crops to increase yields compared to non-altered baselines.8  

Conclusion: Important to Keep All the Doors Open That We Can

2022 has been a stressful year in many respects. Higher inflation is stressful. Market performance is stressful. Thinking about a possible recession across much of the developed world is stressful. The fact that COVID-19 is still with us is stressful. The list goes on and on. 

Thematic equity strategies, at their core, are about finding companies that are seeking to provide solutions for the big problems and the big questions. If the world is to support roughly 10 billion people by 2050—in a way that is as close to net neutral on a carbon emissions basis as possible—it is likely we will need to explore many solutions. How we decide to grow food is at the core of that.
