The event Cumulus Mumbai 2015: 'In a Planet of Our Own' was being held in Mumbai, India, in December 2015, hosted by the IDC School of Design (IDC) at the Indian Institute of Technology Bombay (IIT Bombay). This international event aimed to create design awareness on sustainability, focusing on water and simultaneously offering a platform for interaction for the art, design, and media communities. The events were centred around the interests of students, educationalists, and practicing professional designers. The event had been designed to be lively, interactive, and thought-provoking. It provided a great opportunity to converse with grandmasters of design, interact with thought leaders, and listen to visions by outstanding speakers. The event has shed light on the role of art, design, and media in an interconnected global world within the context of sustainability.
