Catalysts in Concrete: Public Art as a Tool for Social Change

At Mumbai’s Sassoon Dock, The Wasteland by Michael Zeller—a towering assemblage of discarded plastics—rises against the harbour’s humid backdrop. Created for the city's annual art festival in 2022, it records oceanic pollution and sparks conversation. Passersby stop, some snapping photos, others debating its implications. The work’s rough-hewn aesthetics may seem decorative, yet surrounding programming—workshops on waste separation, fisherfolk panels, and guided tours—positions it as a site of engagement.

Public art now serves a participatory function. Projects depend on community involvement as a measure of success. This reflects a blend of urban design and social practice, where the line between creator and viewer blurs in spaces designed to provoke.

In 2014, the Jaipur-based NGO Morarka Foundation launched The Wall of Wishes, a mural project in Rajasthan’s Shekhawati villages. Residents inscribe their aspirations directly onto village walls, guided by artists who translate text into elaborate visual motifs. These murals evolve as aspirations change, embodying collective narratives. Kamal Morarka, the foundation’s director, states, “The murals document not only history but hope. They belong to the community because they emerge from it.”

Scale transforms public art, especially in urban centres where installations navigate dense populations. In São Paulo, Brazil, The People’s Square by Giselle Beiguelman reimagines a derelict car park into a multifunctional cultural space. Digital projections of oral histories illuminate its concrete facades each evening, sourced from interviews with residents of surrounding favelas. Completed in 2019 with support from the São Paulo Municipal Modern Art Fund, this project bridges societal divisions through direct engagement with lived realities.

Technological innovation expands public art's scope. Interactive installations like TeamLab’s Resonating Trees (2018) in Tokyo’s Rikugien Gardens use motion sensors to create dynamic light displays that respond to visitors’ movements. While visually captivating, the installation’s appeal lies in its participatory design—its luminous choreography changes as a result of human interaction. Similarly, Rafael Lozano-Hemmer’s Border Tuner (2019) connects communities on either side of the US-Mexico border through interactive light beams. Lozano-Hemmer describes these works as “platforms for connection, where technology mediates empathy not by replacing human contact but by amplifying it.”

However, the shift toward participatory public art faces critique. Some argue that reliance on community interaction risks instrumentalising art for social utility, diminishing its aesthetic autonomy. Projects funded by municipal or corporate bodies often blur the line between genuine engagement and tokenism. In Mumbai, the Kala Ghoda Fibreglass Animals display faced backlash in 2023 for its lack of public consultation, with critics calling it “artwashing” gentrification efforts in the historic district. When public art becomes a branding exercise, its potential for meaningful dialogue diminishes.

This tension raises a question: Should public art serve an aesthetic purpose, or must it fulfil a civic function? Historical precedents suggest this dichotomy is false. Diego Rivera’s murals of the 1930s and Robert Smithson’s Spiral Jetty (1970) are visually commanding and deeply intertwined with their social contexts. Contemporary public art distinguishes itself not by content but by process: the extent to which it involves and evolves with the communities it addresses.

The success of such projects hinges on collaboration. Danish-Icelandic artist Olafur Eliasson is known for large-scale participatory installations that balance environmental consciousness with artistic ambition. His Little Sun project, initiated in 2012, distributes solar-powered lights to off-grid communities worldwide, funded through sales of the same lights in affluent contexts. Eliasson comments, “Every public artwork is an invitation, not an instruction. The most important thing is what happens after the viewer leaves.”

As urbanisation accelerates and socio-political divides deepen, public art’s role as a mediator between individuals and institutions gains urgency. Claire Doherty, in her 2015 book Out of Time, Out of Place: Public Art Now, states, “Public art needs to work with, rather than on, its audiences. It’s not a monologue; it’s a conversation.”

How that conversation unfolds depends on local contexts. In some cities, it might mean reclaiming neglected spaces. In others, it might amplify marginalised voices. The stakes remain consistent: Public art confronts its audience not as spectators but as participants in a shared urban narrative. Whether those narratives lead to transformative change or fleeting interaction is unresolved, but that uncertainty makes such works vital. The gap between intent and impact is where engagement occurs.
