The current agricultural model relies heavily on monocultures and intensive use of chemical pesticides. This method depletes the soil and leaves crops essentially defenseless against natural enemies.
Old agricultural crops offer a way out of this dependency through their natural strength. These forgotten varieties restore biological diversity and reduce the need for toxic chemicals in our food chain.
The 5 Key Takeaways
- Monocultures function as an unlimited buffet for specialized pests due to lack of genetic variation
- Dutch biodiversity has shrunk by 85 percent since the last century due to intensive pesticide use
- Old grain varieties like emmer wheat possess a more robust genetic foundation that naturally keeps diseases at bay
- Regional collaborations prove that reintroducing forgotten crops is economically viable for local farmers
- Using diverse crops on a single field creates a self-regulating ecosystem that requires less external intervention
The Vulnerability of Monocultures
Monocultures create an ideal buffet for specialized diseases and pests. Because a field contains genetically nearly identical plants, disease spreads rapidly, as PAN Europe clearly describes on their website.
Diverse planting effectively breaks this destructive pattern. Crop variation significantly reduces the chance of large-scale pest outbreaks, according to insights from WUR eDepot on mixed cropping systems.
Environmental Damage from Pesticide Use
Excessive use of chemical pesticides comes at a high cost to our environment. Residues of these substances appear in our drinking water and even in human body tissue, as PAN Europe rightfully reports.
In half of Dutch waterways, pesticides exceed legal limits. This causes massive die-offs among aquatic organisms and weakens the natural enemies that should suppress pests.
Pros and Cons of Forgotten Crops
Pros
- Broader genetic foundation reduces susceptibility to aggressive plant diseases
- Dramatic increase in biodiversity on agricultural fields
- Presence of natural defense mechanisms against various pests
- Function as a form of preventive crop protection without chemicals
Cons
- Lower yields per hectare compared to modern hybrid varieties
- Limited knowledge about optimal cultivation methods among current farmers
- Low awareness among the general public and in regular supermarkets
- Lack of large-scale infrastructure for processing and logistics
Old grain varieties like this barley support the local economy and biodiversity.
Local Initiatives with Forgotten Crops
In the Netherlands, examples like Stadsbrouwerij Wageningen show that revaluation works. They brew beer with traditional barley grown locally on the Wageningse Eng.
In the IJsseldal, pioneers work with millers to reintroduce grain varieties like emmer and einkorn. According to WUR eDepot, these old varieties naturally suffer much less from fungal diseases.
Hof van Twello as a Testing Ground for Diversity
At Hof van Twello, a wide range of forgotten vegetables are finding their place in the fields again. Crops like parsnip and parsnip parsley are central here, as described in WUR eDepot reports.
These initiatives prove that growing old varieties is actually possible in current practice. The products are now finding their way to consumers who make more conscious choices for quality and the environment.
Glossary
- Monoculture: Agricultural method in which only a single crop is grown over large areas
- Spelt: Old grain variety that is less refined and therefore more robust against pathogens
- Biodiversity: The total variety of living organisms in a specific habitat
- Jerusalem Artichoke: Winter-hardy tuber crop with a distinctive flavor that requires minimal maintenance
Environmental and Economic Benefits
Growing these old varieties contributes to richer biodiversity around farmland. WUR eDepot confirms that non-hybrid crops increase the natural resilience of the entire ecosystem.
Moreover, these fields function as a living gene bank for the future. According to WUR, these unique properties are essential for developing crops that can withstand climate change.
Challenges in Scaling Up
Despite all biological Pros, bottlenecks remain when scaling up. Many forgotten varieties typically produce smaller harvests and don’t meet the strict uniformity requirements of large retail chains.
Specific cultivation knowledge has unfortunately been partially lost over recent decades. Maintaining consistent demand remains a challenge for many organic farmers in a market focused on mass production.
These forgotten varieties each have their own strengths:
| Crop | Nutritional Value and Flavor | Harvest Period |
|---|---|---|
| Spelt | Rich in proteins and fiber with a nutty flavor. | July |
| Einkorn | High antioxidant content and important minerals. | July |
| Emmer | Contains plenty of iron and zinc for a complete diet. | July |
| Parsnip | Good source of vitamin C and potassium with a sweet aroma. | November |
| Jerusalem Artichoke | Rich in prebiotic fiber for gut health. | October |
The Biological Eye-Opener
The core lies in the “genetic arms race.” Modern crops have partially lost their natural immune system through intensive breeding in exchange for maximum yield. Forgotten crops still possess their original biochemical defense mechanisms, such as specific alkaloids and secondary plant compounds. These substances work as a built-in biological shield, making the plant less dependent on external chemical intervention to survive.
Conclusion
Forgotten crops offer a real perspective to break the negative spiral of monocultures and chemical pest control. They increase natural resilience and make our agriculture sustainable in the long term.
The successes of Dutch pioneers show that a shift toward more diversity is indeed possible. Investing in these old varieties is not a step backward, but a necessary move toward a healthier and stronger food system.

Frequently Asked Questions
Which forgotten crops work best in the Dutch climate?
Old grain varieties like spelt and emmer wheat actually thrive on our soil. Root crops like parsnip and Jerusalem artichoke are also very winter-hardy and require minimal extra protection against the cold.
How can I as a consumer encourage the cultivation of these old varieties?
By consciously choosing products at farmers markets and local farm shops, you help directly. Consumer demand is what determines whether a farmer dares to dedicate a field to these special varieties.
Are forgotten crops automatically healthier than modern varieties?
They often contain higher concentrations of specific minerals and fiber because they grow more slowly. Additionally, you consume fewer chemical residues, which is perhaps the biggest benefit for your own body.
What is actually the difference between a heritage variety and a forgotten crop?
A forgotten crop is simply a variety that has disappeared from common use. Heritage varieties are specific cultivars that have often been passed down for generations in a particular region because of their unique properties.
Can I buy seeds of these crops myself for my garden?
That is certainly possible through specialized suppliers focused on biodiversity. Growing einkorn or parsnip yourself is a nice way to increase natural variety in your own surroundings.
