STUDY LINKS POLLINATOR DECLINE TO HUMAN NUTRITION LOSS IN NEPAL

A study published in the journal Nature has found that pollinators are directly responsible for more than 20% of vitamin A, vitamin E and folate intake among residents of remote villages in Nepal's Jumla district. Researchers tracked diets, crop yields, farming income and pollinator interactions with crops across 10 villages over one year. The team counted pollen granules on bee bodies as part of the data-gathering process. Pollinators were also found to account for 44% of farming income in the area.

The research was led by Thomas Timberlake, an ecologist at the University of York, alongside colleagues. Jumla district is home to approximately 120,000 people and is accessible by land only via the Karnali highway. Most residents are self-sufficient, relying on what they grow for both food and income. Local beekeepers have reported that roughly half of their bees have disappeared over the past decade, with honey production falling as a result. The authors describe the study as the first of its kind to provide direct evidence of a link between pollinator populations and human health outcomes.

Timberlake noted that the communities involved are geographically isolated with limited trade connections, meaning residents cannot easily replace declining local food production with imported alternatives. The findings indicate that the loss of pollinators carries consequences beyond agriculture, extending into nutritional security for vulnerable populations. Jumla's food insecurity and malnutrition were identified as existing pressures compounding the risk. The study adds quantified evidence to broader scientific concern about the global decline of wild bee populations.
