Yamuna River Project: New Delhi Urban Ecology

Alday and Pankaj Vir Gupta’s Yamuna River Project extends the principles of water-as-structure to the 22-kilometer stretch of river bisecting New Delhi — 2 percent of the Yamuna’s length carrying 76 percent of its pollution load. The five-year research initiative rejects siloed engineering in favor of “Urban Layers” analysis: historical water logic, topography, mobility, demographics, and pollution sources superimposed to reveal hidden correlations.

The methodology validates the thesis’s approach to Lahaina. Superimposing pre-plantation wetland maps over modern zoning reveals erased hydrological logic. The streams that fed Mokuhinia, the irrigation channels that sustained lo’i kalo, the drainage patterns that distributed water mauka to makai — these persist as topographic traces even where infrastructure has been removed or buried.

The Yamuna project proposes “hybrid infrastructures” that co-locate utilities with public program: a pedestrian bridge functioning as filtration dam and vegetable market; a library built atop a treatment tank; sanitation hubs recycling water and generating biogas for community kitchens. The thesis adopts the same principle. Lahaina’s water reservoirs should not be fenced utilities but public pavilions. Cisterns function as shaded gathering spaces. Pump houses double as community centers. The operational requirement is identical — store and move water — but the spatial product serves daily life rather than sitting empty until emergency.

The Yamuna framework also raises a warning that the thesis takes seriously. Riverfront beautification in Delhi has historically produced eviction of slum dwellers and displacement of small-scale farmers who work floodplains. Green infrastructure must not become a gentrification tool. Lahaina’s recovery must integrate existing landowners and long-term renters into ecological zones as stewards rather than obstacles.
