Gelephu Mindfulness City (GMC) is a planned 2,500 km² Special Administrative Region in Sarpang District, southern Bhutan. While promoted as a model of sustainable development with mandates for carbon-negative buildings, biodiversity corridors, and renewable energy, the project's location in one of Bhutan's most ecologically sensitive regions has raised questions about its environmental compatibility. The development area sits between the Phibsoo Wildlife Sanctuary and Royal Manas National Park and lies on a subtropical floodplain that receives some of the heaviest rainfall in the eastern Himalayas.

Ecological Setting

The GMC footprint is situated in the southern foothills of Bhutan, at elevations between 200 and 450 meters above sea level. The area lies within the Eastern Himalayan Biodiversity Hotspot, one of the world's 36 recognized biodiversity hotspots. The project area borders or overlaps with three key elements of Bhutan's protected area network:

Royal Manas National Park (1,057 km²): Bhutan's oldest national park, established in 1966, contiguous with India's Manas National Park. It is home to Bengal tigers, Asian elephants, golden langurs, pygmy hogs, and over 360 bird species. It has been designated a UNESCO World Heritage Site buffer zone.
Phibsoo Wildlife Sanctuary (278 km²): Bhutan's only tropical wildlife sanctuary, containing the country's only natural sal (Shorea robusta) forest and populations of Asian elephants, gaur, and tigers.
Biological Corridor: A designated wildlife corridor connecting Phibsoo and Royal Manas, through which elephants, tigers, and other species migrate between the two reserves.

Bhutan's 2021-22 national tiger survey estimated 131 wild tigers in the country — a 27 percent increase over the 2015 count — with Phibsoo and Royal Manas forming part of a critical trans-boundary tiger landscape shared with India.^[1]

Wildlife Corridor Fragmentation

The central environmental concern is whether a development designed to accommodate up to one million people can coexist with functioning wildlife corridors. The BIG masterplan states that it "retains all existing forests" and integrates "functional corridors for elephants to move to places for birthing, foraging, and migration."^[2] The plan maps rivers, canals, and ecological corridors as areas "not to be touched."

However, critics note a tension between these claims and the development's scale. Asian elephants require extensive home ranges — typically 100 to 1,000 km² depending on habitat quality. Collared elephants from Phibsoo Wildlife Sanctuary have been tracked migrating through the Gelephu area toward Indian forest reserves, demonstrating that the development zone is not adjacent to but within active migration routes.^[3] Human-elephant conflict is already a significant issue in the Gelephu area, with elephants raiding crops of areca nut, oranges, ginger, and cardamom in existing agricultural settlements.

Research published in 2024 on connectivity and conflict modeling for Asian elephant conservation in south-central Bhutan identified the Gelephu corridor as critical for maintaining genetic connectivity between elephant populations in Phibsoo and Royal Manas.^[4] A city of potentially hundreds of thousands of residents, with associated road networks, lighting, noise, and industrial activity, would substantially alter the viability of these corridors regardless of design provisions.

Flood Risk and Climate Challenges

Gelephu sits on an alluvial floodplain formed by riverine deposits from Himalayan rivers. The area receives between 4,000 and 7,500 millimeters of annual rainfall, concentrated during the summer monsoon from June through September.^[5] Flash floods and landslides are recurring events in the monsoon season. A government flood hazard assessment for Sarpang Dzongkhag identified the Mao River at Gelephu as requiring specific flood risk study.^[6]

The BIG masterplan addresses flood risk through "multifunctional blue and green corridors" and natural reed beds for water treatment. However, the adequacy of nature-based solutions for managing monsoon flooding at the scale of a major city remains untested. Climate change projections for the eastern Himalayas suggest increasing intensity of extreme rainfall events and accelerating glacial melt, both of which would compound flood risk in downstream areas like Gelephu.

Gelephu is also one of Bhutan's hottest locations. Subtropical temperatures regularly exceed 35°C during summer months, with humidity amplifying thermal discomfort. Building a densely populated city in this climate would require significant energy for cooling — potentially conflicting with carbon-negative targets — and raises livability questions for the "mindful" lifestyle the project promotes.

Carbon Negativity Contradictions

Bhutan is one of the world's few carbon-negative countries, absorbing more CO2 through its forests than it emits. This status is central to Bhutan's international identity and diplomatic positioning. GMC's promotional materials mandate "carbon-negative buildings," renewable energy for all electricity, organic food production, and electric or non-motorized transportation.^[7]

Critics have questioned whether these claims account for the full lifecycle emissions of constructing a $100 billion city. Cement and steel production — essential for large-scale construction — are among the world's most carbon-intensive industries. The embodied carbon in buildings, roads, an international airport (Phase 1 capacity: 1.3 million passengers annually, expanding to 5.5 million), and a hydroelectric dam would be substantial. The construction workforce, materials supply chain, and associated logistics — much of which would originate from India — would generate emissions not captured in GMC's operational carbon accounting.

The broader question is whether a mega-city development of this scale is compatible with maintaining Bhutan's carbon-negative status, or whether GMC's environmental branding represents what critics of similar projects have termed "greenwashing" — using sustainability language to market a fundamentally carbon-intensive development.

Water Resources

A city designed for up to one million residents would place substantial demands on water resources in the Gelephu area. While the region has abundant rainfall during the monsoon, water availability during the dry season (November to March) is significantly lower. The development of water supply infrastructure sufficient for a major city — including municipal supply, sanitation, industrial use, and irrigation for organic agriculture mandates — has not been detailed in public documentation.

Water quality is also a concern. The natural reed beds proposed for water treatment in the masterplan are typically effective for small-scale applications but have limited capacity for treating municipal wastewater from large populations. Whether such systems could handle the volume generated by hundreds of thousands of residents while meeting environmental standards is uncertain.

Environmental Impact Assessment Status

Bhutan's regulatory framework requires Environmental Impact Assessments (EIAs) for major development projects, submitted to the Department of Environment and Climate Change (DoECC) for environmental clearance. As of early 2026, no comprehensive EIA for the full GMC project has been publicly released. Individual infrastructure components, such as the Gelephu-Tareythang Road, have undergone separate environmental review. The World Bank-funded road project identified the area as critical habitat for Asian elephants and Gee's golden langur, requiring biodiversity management plans and net-gain strategies.^[8]

The absence of a comprehensive, publicly available EIA for a 2,500 km² development — before construction activities have already commenced — represents a significant gap in environmental governance. International best practice calls for strategic environmental assessment at the master-plan stage for developments of this scale, not piecemeal assessment of individual components.

Proponents' Response

The Bhutanese government and project designers have emphasized that environmental sustainability is foundational to GMC's concept. Arup, the engineering consultancy working on the project, describes the masterplan as following "a regenerative approach" with neighborhoods designed to "follow natural contours, enhancing waterways and integrating them into public spaces."^[9] WWF Bhutan has described the project as a "blueprint for resilience in the 21st century," emphasizing the integration of protected areas into the city's design.^[10] Forest officials have stated they are tracking elephant herd movements to ensure wildlife corridors between Phibsoo and Royal Manas remain undisturbed as the project develops.
