科学｜奈良の赤トンボ激減の影響 / Science | The Impact of the Dramatic Decline of Red Dragonflies in Nara

Summary

The representative species of the red dragonfly, the Akiaakane, has seen a dramatic decline nationwide, with reports indicating that its population in Nara Prefecture has decreased to between one-hundredth and one-thousandth of what it was 30 years ago.

Particularly significant reductions have been observed in extensive areas such as the Heijokyu Ruins Historical Park. The causes cited include the loss of rice fields and wetlands, as well as the use of pesticides that affect the Akiaakane. Experts point out that these factors are contributing to the widespread decline.

Dialogue

This dialogue is fictional and based on the article.

Log: Did you know that the number of red dragonflies has been drastically declining recently? In some areas of Nara, it’s dropped to one-thousandth of what it was 30 years ago.
Chako: Really?! Why have they decreased so much?
Log: Well, it’s because of the reduction in rice fields and wetlands, and it seems that pesticides have a strong impact on the Akiaakane (red dragonfly).
Chako: So pesticides are the cause! That’s kind of worrying.
Navi: The effects of pesticides on ecosystems can be quite diverse. They can have serious impacts, especially on sensitive species, so we need to be careful.
Chako: So, what can we do to protect the red dragonflies?

Admin’s Note

Reading this article made me reflect on how the decrease in red dragonflies impacts our living environment. It’s particularly concerning that even historically significant places like Nara are facing threats to their ecosystems. I believe it is crucial to reevaluate the use of pesticides and to prioritize the conservation of wetlands. Additionally, the willingness of younger generations to engage in conservation efforts is also important. I would like us to think together about what we can do to help.
