A swarm of stink bugs and a river of rats: why India’s flowering bamboo causes a crisis for humans

Summary

India's bamboo flowering cycle triggers rodent outbreaks, causing famine and crop destruction. This natural phenomenon leads to soil erosion and ecosystem shifts, impacting livelihoods and food security.

Key Takeaways

1. The mass flowering of bamboo species in Mizoram, India, known as mautam and thingtam, triggers a significant increase in rodent populations.
2. The rodent outbreaks lead to widespread crop destruction, particularly rice, causing famine and severe economic hardship for local farmers.
3. Beyond crop losses, the natural death of bamboo after flowering increases soil erosion risk and impacts the wider ecosystem, affecting biodiversity and natural regeneration.
