The world is undergoing a profound transformation with far-reaching consequences for economic, social and environmental systems. This new era, often described as the Intelligent Age, is being shaped by rapid advancements in AI, robotics, biotechnology, quantum computing and digital infrastructure. Just as the shift from an agricultural society to an industrial one altered the global order, the Intelligent Age is set to redefine how people live, work and connect with their surroundings.
Bharat stands at a critical juncture in its economic journey. Policy stability, deepening reforms, robust domestic consumption and a favourable demographic dividend have helped the country emerge as the fifth-largest global economy with a GDP of around four trillion dollars. Despite global disruptions, Bharat has maintained steady growth of seven to eight percent and continues to be the fastest-growing major economy. A strong emphasis on infrastructure and manufacturing has strengthened its global position. Coupled with a vast talent pool, an innate culture of innovation and decisive government support for digital transformation, Bharat is uniquely placed to lead in this new age.
Between 2018 and 2025, the IITs delivered sixteen landmark environmental technologies that promote national self-reliance, reduce dependence on foreign systems and reinforce India’s long-standing civilisational commitment to ecological balance. These innovations advance key national missions such as Aatmanirbhar Bharat, Swachh Bharat, the National Clean Air Programme, the National Water Mission, the Green Hydrogen and Biofuel Mission and Make in India along with rural development programmes.
