‘Day Zero’ concentrates on a segment of my research from the larger study of water and mountain ecologies in the Himalayan and Eastern and North-Eastern regions. The idea was to present it as an immersive simulation, complete with video sculptures. The work derives from image-based, geological and climatic evidence of ecological and infrastructural violence. The tendency of humankind towards formal/structural reinvention troubles the protocols used for scientific exploration and political organisation of water. It further undergirds the consequences of its unequal use and distribution. The simulation presents a landscape without humans for us to temporarily occupy, turning participants into witnesses of a possible future. It uses the atmosphere as a site to stage the politics of water–as a melting, evaporating surface, as currency and its vulnerability to toxicity, contamination and contagion.
