The National Highways Authority of India (NHAI) has announced a first-of-its-kind ‘Bee Corridor’ initiative to develop pollinator-friendly stretches along National Highways. Moving beyond ornamental roadside plantations, the initiative aims to integrate ecological restoration with infrastructure expansion. At a time when pollinator populations are under stress, this move seeks to align highway development with biodiversity conservation and agricultural sustainability.
What Is the Bee Corridor Initiative?
National Highways Authority of India (NHAI) plans to create continuous linear stretches of bee-friendly vegetation along National Highways.
Key features include:
- Planting nectar- and pollen-rich species.
- Ensuring staggered flowering throughout the year.
- Allowing flowering weeds and wild elements to persist.
- Retaining dead wood and hollow trunks beneficial for pollinators.
Clusters of flowering trees will be planted at intervals of 500 metres to 1 km, corresponding to the average foraging range of honeybees and wild bees.
During 2026–27, NHAI plans to plant around 40 lakh trees, with nearly 60% under the Bee Corridor initiative.
Why Pollinators Matter for India
Pollinators such as honeybees, butterflies, and other insects are essential for crop reproduction. Globally, a significant proportion of food crops depend on animal-mediated pollination.
Declining bee populations are linked to:
- Habitat loss and fragmentation.
- Excessive pesticide use.
- Climate change.
- Monoculture practices.
In India, reduced pollination services can adversely impact agricultural and horticultural productivity, threatening food security and farmer incomes.
From Ornamental Plantations to Ecological Design
Traditionally, roadside plantations prioritised aesthetic appeal and dust control. The Bee Corridor marks a conceptual shift toward ecological landscaping.
Native species such as Neem, Karanj, Mahua, Palash, Bottle Brush, Jamun, and Siris will be planted based on agro-climatic suitability.
This approach aims to:
- Create micro-habitats along transport corridors.
- Enhance biodiversity in degraded landscapes.
- Promote ecological connectivity between fragmented habitats.
- Support year-round nectar availability.
Such ecological corridors can mitigate the barrier effect often caused by highways.
Infrastructure and Environmental Governance
The initiative aligns with India’s commitments under:
- National Biodiversity Action Plan.
- Climate adaptation strategies.
- Sustainable Development Goals (SDGs), especially SDG 15 (Life on Land).
By embedding ecological design into infrastructure projects, NHAI reflects a broader policy trend toward green highways and environmentally responsible development.
Implementation Challenges
While innovative, effective implementation requires:
- Careful species selection based on local ecosystems.
- Long-term maintenance and monitoring.
- Coordination with forest and agriculture departments.
- Mitigation of pesticide drift from adjoining farmlands.
Additionally, ecological corridors must be scientifically evaluated to ensure they genuinely enhance pollinator diversity and do not become token plantation exercises.
Broader Significance for Sustainable Infrastructure
India has one of the world’s largest road networks, and highway expansion is central to economic growth. Integrating biodiversity into transport planning can transform linear infrastructure into ecological assets.
The Bee Corridor initiative demonstrates that:
- Infrastructure need not be ecologically disruptive.
- Green corridors can serve both environmental and economic goals.
- Pollinator conservation is directly linked to agricultural resilience.
If successful, the model could be replicated in railways, urban roads, and industrial corridors.
