Sikkim's Yakten Village Uses Hydrological Mapping and AI to Plan Water Security

Yakten, a village in Sikkim's Pakyong district that was promoted as India's first digital nomad village, is now undertaking detailed hydrological mapping and spring recharge interventions to plan for long-term water security under changing climate conditions. Working with environmental consultancy BETWA Solutions and the local government, the village is implementing a phased plan including recharge pits, rooftop rainwater harvesting, new storage ponds and a gravity-fed distribution system.

BETWA's hydrological study drew on 76 years of India Meteorological Department rainfall data from 1950 to 2025, finding that while annual rainfall in the region has gradually increased, a growing proportion now arrives in short, intense bursts that run off steep slopes rather than percolating into the ground to recharge springs. In El Nino years in particular, this pattern can leave the village drier than usual even after a wet monsoon season. Yakten's springs are fed by rainfall percolating through hillsides, but slopes steeper than 35 degrees and south-east-facing aspects limit the land's natural capacity to capture and hold rainwater. Reduced forest cover has further diminished the land's infiltration efficiency.

During a field visit conducted with the Rural Development Department, four key water bodies were mapped: the Bhiwsa spring and Hel Khola water sources, and two ponds, Ladey Pokhri and Sookhi Pokhri. Bhiwsa spring is the village's main water source, and its recharge zone in the immediate uphill area was identified for targeted interventions. Recharge pits filled with phyllite stones have already been dug in two priority zones to channel water past the clay layer and into the aquifer. The team also used artificial intelligence for citizen science data collection, engaging tourists visiting the village to help build a baseline understanding of water demand and usage patterns.

The longer-term plan includes new storage ponds to buffer supply during dry spells and a gravity-fed system drawing from higher-elevation ponds, monitored by low-cost sensors and managed by the community. Meteorological agencies including the United States' National Oceanic and Atmospheric Administration predict an 82 per cent chance of El Nino conditions developing between May and July 2026, with a nearly 100 per cent probability of a super El Nino forming by November, making Yakten's preparedness work timely. The village's approach, treating water planning as part of the same ethos guiding its tourism model, offers a replicable example of climate-smart community planning for Himalayan villages where tourism growth and ecological resilience must advance together.
