- Saving bees is crucial for global nutrition, as 75% of food crops rely on pollination, supplying essential micronutrients.
- Pollinator populations in regions like Nepal’s Jumla Valley directly correlate with household food availability and income.
- Insect pollination is responsible for the majority of global food crop pollination, with essential micronutrients in fruits and vegetables.
- Pollinator-dependent crops contribute to more than 35% of global crop production by volume, valuing $235–577 billion annually.
- In low-income agrarian communities, protecting pollinators is a direct investment in food security and rural livelihoods.
Protecting pollinating insects is not merely an ecological imperative—it is a direct investment in global nutrition, food security, and rural livelihoods. Evidence increasingly shows that the decline of bees, butterflies, and other pollinators threatens the diversity and quality of human diets, particularly in low-income agrarian communities. In regions like Nepal’s Jumla Valley, where subsistence farming dominates, the health of pollinator populations directly correlates with household food availability and income from high-value crops such as apples and pumpkins.

Global food systems depend on insect pollination
\n
Approximately 75% of the world’s food crops depend, at least partially, on animal pollination, with insects responsible for the majority of this service, according to the Food and Agriculture Organization (FAO) of the United Nations. These crops—including fruits, vegetables, nuts, and oilseeds—supply essential micronutrients like vitamin A, folate, and iron, which are critical for preventing malnutrition. A 2021 study published in Nature Sustainability estimated that pollinator-dependent crops contribute to more than 35% of global crop production by volume. The economic value of pollination services is pegged at $235–577 billion annually. In Nepal, where over 70% of the population relies on agriculture, crops such as apples in Jumla, cardamom in Ilam, and mustard across the mid-hills benefit significantly from insect pollinators, with yields dropping by up to 40% in their absence.

Key actors: farmers, scientists, and policymakers respond
\n
In Jumla, farmers like 42-year-old Phurba Tamang have observed fewer bees in recent years, coinciding with reduced apple fruit set and smaller pumpkins. In response, local agricultural cooperatives, supported by Nepal’s Ministry of Agriculture and Livestock Development and international NGOs such as the International Centre for Integrated Mountain Development (ICIMOD), have launched pollinator conservation initiatives. These include planting native flowering hedgerows, reducing pesticide use, and training farmers in bee-friendly practices. Meanwhile, scientists from Tribhuvan University are monitoring pollinator biodiversity across the Himalayan region, providing data to shape national policy. Globally, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has identified pollinator decline as a critical risk, prompting countries like Germany and France to implement national pollinator strategies with binding pesticide regulations and habitat restoration targets.
\n\n
Trade-offs between short-term yields and long-term resilience
\n
Protecting pollinators often requires farmers to forgo short-term gains from intensive pesticide use or land conversion. In remote areas like Jumla, where access to markets is limited and financial margins are thin, such trade-offs are challenging. However, evidence suggests long-term benefits outweigh immediate costs. For example, ICIMOD’s pilot projects in western Nepal showed that farms adopting pollinator-friendly practices saw apple yields increase by 23% within three years, alongside a 30% rise in household income from surplus sales. Conversely, unchecked use of neonicotinoid pesticides—known to harm bee navigation and reproduction—has been linked to colony collapse and reduced crop diversity. While synthetic inputs may boost yields of staple grains like rice, they undermine the very ecosystems that support nutrient-rich foods, potentially exacerbating hidden hunger and diet-related diseases.
\n\n
Why pollinator protection is urgent now
\n
The urgency stems from converging crises: biodiversity loss, climate change, and global malnutrition. A 2023 IPBES report confirmed that 40% of invertebrate pollinator species, particularly bees and butterflies, face extinction. Drivers include habitat fragmentation, monoculture farming, climate-induced shifts in flowering times, and widespread pesticide application. In Nepal, rising temperatures are altering the elevation ranges of both crops and pollinators, disrupting long-standing ecological synchrony. Simultaneously, global demand for nutrient-dense foods is rising, placing further strain on pollinator-dependent supply chains. The World Health Organization has flagged the decline of pollinators as a ‘silent threat’ to achieving Sustainable Development Goals related to zero hunger and good health.

Where We Go From Here
\n
Over the next 6–12 months, three scenarios could unfold. In an optimistic scenario, increased funding and policy coordination could scale up agroecological practices, integrating pollinator conservation into national agricultural subsidies, as seen in parts of the European Union. A middle path might see incremental change, with pilot programs expanding but lacking systemic integration, leaving smallholders vulnerable. In a pessimistic scenario, continued land-use intensification and climate volatility could accelerate pollinator loss, triggering localized food shortages and economic strain in rural communities. The trajectory will depend on whether governments prioritize ecological health as foundational to food security, rather than a secondary concern.
\n\n
Bottom line — safeguarding pollinating insects is a cost-effective, scalable strategy to improve diets, support rural economies, and build resilience against future shocks in a warming world.
