How Climate Change Is Threatening Indian Honey Production

Updated April 2026

India is the world's eighth-largest honey producer and home to an estimated 12 million bee colonies. But this vital industry, which supports hundreds of thousands of beekeepers and millions of pollination-dependent farmers, is facing an unprecedented crisis. Climate change is fundamentally altering the conditions that bees need to thrive, threatening both honey production and the broader agricultural ecosystem that depends on pollination.

From shifting flowering seasons in the Himalayas to extreme heat events killing bee colonies in the plains, the impacts are already visible. Understanding these threats is essential not only for honey lovers and conscious consumers but for anyone who cares about food security in India. In this article, we examine how climate change is affecting Indian honey production, what it means for the future of raw honey, and what we can all do to help.

India's Beekeeping Landscape: What Is at Stake

India's beekeeping industry is remarkably diverse. The country is home to four major honey bee species: Apis cerana indica (the Indian hive bee), Apis dorsata (the giant rock bee), Apis florea (the little bee), and the introduced Apis mellifera (the European honey bee). Each species occupies different ecological niches and responds differently to environmental changes.

The major honey-producing regions include:

• The Himalayan belt (Uttarakhand, Himachal Pradesh, Jammu and Kashmir): Home to multifloral wild honey, including the varieties sourced by Pahadi Source
• The Nilgiri Hills (Tamil Nadu, Kerala, Karnataka): Known for wild forest honey and coffee blossom honey
• The Gangetic plains (UP, Bihar, West Bengal): Major migratory beekeeping zone for mustard and litchi honey
• Rajasthan and Gujarat: Important for mustard honey and ber (jujube) honey
• The Sundarbans (West Bengal): Famous for wild mangrove honey collected by traditional honey hunters

According to the National Bee Board, India produced approximately 133,000 metric tonnes of honey in 2024-25. However, this figure masks significant regional declines and increasing volatility in year-to-year production.

How Climate Change Affects Bees

Rising Temperatures and Heat Stress

Bees are cold-blooded insects that rely on environmental temperatures to regulate their body functions. When temperatures exceed 40-42 degrees Celsius, which is increasingly common across India's plains during summer, bees experience severe heat stress. Worker bees stop foraging and instead spend their energy fanning the hive to cool it down. In extreme heat events, entire colonies can collapse.

A 2023 study by the Indian Agricultural Research Institute found that heat waves reduced honey yields by 30-50 percent in affected regions. As heat waves become longer and more intense due to climate change, this problem will only worsen.

Shifting Flowering Seasons

Bees depend on predictable flowering patterns. They have evolved synchronized lifecycles where colony population peaks coincide with major nectar flows. Climate change is disrupting this synchrony in several ways.

Earlier blooming: Many plants are flowering 2-3 weeks earlier than they did a decade ago. If bee colonies have not yet built up sufficient forager populations when flowers bloom, the nectar flow is wasted.

Shortened flowering periods: Higher temperatures can cause flowers to bloom and wilt more quickly, reducing the window during which bees can collect nectar. This directly reduces honey yields.

Altered nectar composition: Higher temperatures and CO2 levels can change the sugar concentration and amino acid content of nectar, potentially reducing its nutritional value for bees.

Unpredictable Rainfall

The Indian monsoon, which drives flowering patterns across the subcontinent, is becoming increasingly erratic due to climate change. Both excessive rainfall and drought have devastating effects on honey production.

Heavy rainfall during flowering season washes away pollen and prevents bees from foraging. Waterlogging kills ground-nesting wild bee species. Extended wet periods promote fungal diseases in bee colonies.

Drought causes flowers to produce less nectar or fail to bloom entirely. Bees must travel farther to find food, expending energy that would otherwise go into honey production. Severe drought can cause colony starvation and collapse.

Habitat Loss and Fragmentation

Climate change compounds the existing problem of habitat loss. As traditional flowering landscapes are converted to monoculture farms, urban areas, or degraded by changing weather patterns, bees lose the diverse foraging habitat they need.

In the Himalayas specifically, climate change is causing an upward shift in vegetation zones. Plant species are moving to higher altitudes as temperatures rise, but bee colonies cannot always follow. This is particularly concerning for wild bee species like Apis dorsata, which depend on specific forest ecosystems.

The Himalayan Honey Crisis

The Himalayan region, which produces some of India's finest raw honey including the varieties available from Pahadi Source, is especially vulnerable to climate change impacts.

Glacier retreat and water stress: Himalayan glaciers are retreating at an accelerating rate, affecting the water supply that sustains the meadows and forests where bees forage. Reduced water availability means fewer flowers and less nectar production.

Temperature changes at altitude: The Himalayas are warming at roughly twice the global average rate. This is causing shifts in the distribution of key nectar-producing plants like rhododendron, wild cherry, and various wildflowers.

Extreme weather events: Cloudbursts, unseasonal snowfall, and flash floods are becoming more common in the Himalayan region. These events can destroy entire apiaries and wash away the wildflower meadows that bees depend on.

Invasive species: As temperatures rise, invasive plant species from lower altitudes are moving into traditional foraging zones, outcompeting native nectar-producing plants. Some of these invasive species produce nectar that is toxic or nutritionally poor for bees.

Impact on Specific Honey Varieties

Different honey varieties are being affected in different ways:

Wild Forest Honey: Forest honey from multifloral sources like Pahadi Source Wild Forest Honey depends on diverse forest ecosystems. Deforestation combined with climate-driven changes in forest composition is altering the character of wild forest honey. Some traditional flavour profiles are changing as the mix of flowering species shifts.

Eucalyptus Honey: Eucalyptus honey production is somewhat resilient because eucalyptus trees are hardy and drought-tolerant. However, extreme heat can still reduce nectar flow, and the quality of eucalyptus honey may change as trees experience water stress.

Mustard Honey: Mustard honey is heavily dependent on the mustard crop cycle. Changes in winter temperatures and rainfall patterns directly affect mustard flowering. Farmers in Rajasthan and UP have reported increasingly unpredictable mustard blooms, which makes migratory beekeeping more difficult and risky.

Neem Honey: Neem honey production depends on neem tree flowering, which is triggered by specific temperature and moisture conditions. Climate variability is making neem flowering less predictable, with some years seeing abundant blooms and others seeing almost none.

The Pesticide-Climate Change Double Threat

Climate change does not operate in isolation. It amplifies other threats to bees, particularly pesticide exposure. As temperatures rise and pest pressure increases, farmers tend to use more pesticides, creating a vicious cycle.

Neonicotinoid pesticides, which are widely used in Indian agriculture, are particularly harmful to bees. These systemic insecticides are absorbed by plants and expressed in pollen and nectar, poisoning bees that forage on treated crops. The combined stress of pesticide exposure and heat stress makes bee colonies far more vulnerable to collapse.

This is one of the reasons why honey from wild, pesticide-free sources, like the Himalayan apiaries that supply Pahadi Source, is becoming increasingly precious and important to protect.

What Is Being Done

Several initiatives are addressing the climate-bee crisis in India:

National Bee Board: The government's beekeeping development programme provides support for bee colony multiplication, training, and infrastructure. However, climate adaptation is not yet a major focus.

Traditional knowledge: Indigenous beekeepers in the Himalayas and Western Ghats have generations of knowledge about managing bees in changing conditions. Integrating this traditional wisdom with modern apiculture science is a promising approach.

Habitat restoration: Some NGOs and community groups are planting bee-friendly native species to restore foraging habitat. These efforts are small-scale but crucial for building climate resilience.

Research: Indian agricultural universities are studying the effects of heat stress on different bee species and developing management strategies to help beekeepers adapt to changing conditions.

What Consumers Can Do

As a honey consumer, you have more power than you might think to help address this crisis:

• Buy raw, traceable honey: When you purchase from brands like Pahadi Source that source directly from small-scale beekeepers, you support sustainable apiculture and create economic incentives for bee conservation.
• Choose diverse honey varieties: Buying different types of honey (forest, eucalyptus, neem, mustard) supports beekeepers who maintain diverse foraging landscapes rather than monoculture-dependent operations.
• Plant bee-friendly gardens: Even a small balcony garden with native flowering plants can provide forage for urban bee populations. Choose plants that flower at different times of year to provide year-round food.
• Avoid pesticides: If you have a garden, avoid neonicotinoid pesticides and other bee-toxic chemicals. Choose organic and natural pest management methods.
• Spread awareness: Share information about the connection between climate change, bees, and food security. Many people do not realize that one-third of the food we eat depends on bee pollination.

The Economic Impact

The economic implications extend far beyond the honey industry. Bees pollinate roughly 75 percent of the world's crop species, and the value of pollination services in India is estimated at over 100,000 crore rupees annually, far exceeding the value of honey itself.

Crops that depend on bee pollination include apples (a major Himalayan crop), mangoes, sunflowers, mustard, cardamom, coriander, and numerous vegetable crops. A decline in bee populations does not just mean less honey on your table. It means reduced yields of these essential food crops, higher food prices, and threats to the livelihoods of millions of farmers.

Looking Ahead: The Future of Indian Honey

The future of Indian honey production depends on how effectively we address climate change and protect bee habitats. Some trends to watch include the development of heat-tolerant bee strains through selective breeding, expansion of organic and pesticide-free farming zones, integration of beekeeping with agroforestry and permaculture systems, growth of premium markets for traceable raw honey that rewards sustainable beekeeping, and technology solutions like IoT-enabled hive monitoring that helps beekeepers respond quickly to environmental stress.

For brands like Pahadi Source, the path forward involves maintaining close relationships with beekeepers, ensuring fair prices that make sustainable practices economically viable, and educating consumers about the value of authentic, responsibly sourced honey.

Frequently Asked Questions

How does climate change affect honey quality?

Climate change can alter honey quality by changing nectar composition (sugar content, amino acid profile), shifting the mix of flowering species that contribute to multifloral honeys, and creating stress conditions that cause bees to produce less-mature honey. Raw honey from well-managed apiaries maintains its quality, but the flavour profile may evolve over time.

Is Indian honey production declining?

Overall production figures have remained relatively stable, but this masks significant regional variation. Some areas have seen sharp declines while others have expanded. Production is becoming more volatile year-to-year, with good seasons followed by poor ones, making it harder for beekeepers to sustain their livelihoods.

Are Himalayan honey bees at risk of extinction?

While no Indian bee species is currently classified as endangered, wild populations of Apis cerana indica and Apis dorsata are declining in many areas. The greater risk is local extinction, where bees disappear from specific habitats, leading to pollination failures in those ecosystems.

Why is raw honey more important in the context of climate change?

Raw honey from diverse, pesticide-free sources supports the kind of sustainable beekeeping that builds climate resilience. When consumers pay a premium for quality raw honey, it creates economic incentives for beekeepers to maintain healthy colonies and diverse foraging landscapes.

Can urban beekeeping help offset climate impacts?

Urban beekeeping can make a modest contribution, especially in cities with good green cover. However, the most significant impact comes from protecting and restoring rural and wild bee habitats. Urban gardens and tree planting can help by providing supplementary forage for both managed and wild bee populations.

What honey varieties are most climate-resilient?

Forest honey from diverse ecosystems tends to be more resilient than single-source honeys because the diversity of nectar sources provides a buffer against any one species failing. Eucalyptus honey is relatively resilient due to the hardiness of eucalyptus trees. Mustard honey is more vulnerable due to its dependence on a single crop cycle.

Support sustainable beekeeping: Every jar of Pahadi Source raw honey supports small-scale Himalayan beekeepers who maintain traditional, sustainable apiculture practices. Choose from Wild Forest, Eucalyptus, Neem, or Mustard honey to support diverse bee habitats.
