Pollinators Deliver a Big Bite of Nutrition & Income for Rural Nepal
A new study reveals that pollinators, particularly native honeybees, are responsible for over 20% of essential vitamin intake and more than 40% of farmer income in rural Nepal.
A Direct Line from Bees to Better Health
A study published Wednesday in Nature has quantified the critical role pollinating insects play in human nutrition and economic stability. Researchers tracked the diets of 776 people over one year and surveyed insect activity on farms in rural Nepal.
The findings are stark:
- Pollinators are responsible for more than 20% of the intake of vitamin A, vitamin E, and folate.
- They account for more than 40% of total farmer income.
The Cost of Decline
The researchers project that continued pollinator decline will have serious consequences. By 2030, the loss could reduce vitamin A and folate intake by approximately 7% .
A scenario of complete pollinator loss paints a dire picture:
- Farming income could be cut by nearly 50% .
- Vitamin A and folate intake could drop by 20% .
A Simple Path to Recovery
The study offers a hopeful solution. Simple, low-cost interventions could reverse these trends significantly.

Thomas Timberlake, an ecologist at the University of York who led the research, highlighted the direct link between biodiversity and human well-being.
"The findings show that conserving biodiversity is a substantial public health investment."

Kelvin Mulungu, an agricultural economist not involved in the study, reinforced the broad impact: "Biodiversity supports income, nutrition, and health, especially for vulnerable populations."
