Q. Discuss how indigenous telecom technologies like the Cell Broadcast System can transform India's disaster response from reactive to proactive. (15 marks, 250 words)

India's disaster architecture has long been reactive — mobilising relief after impact. The Cell Broadcast System (CBS), an indigenous C-DOT technology launched in May 2026, shifts the paradigm to proactive, pre-emptive warning by pushing geo-targeted alerts to every handset in a hazard zone [1].

How CBS enables the reactive-to-proactive shift - Speed and reach: a one-to-many broadcast channel delivers near-instant alerts to all phones in a cell area, functioning even during network congestion — plugging the last-mile gap exposed in the 2018 Kerala floods and Cyclone Tauktae [2]. - No app or internet needed, reaching the elderly, rural and mobile-illiterate populations that app-based systems miss. - Standardised: built on the ITU-recommended Common Alerting Protocol (CAP) and integrated with the SACHET platform, ensuring interoperability across all operators [3][4]. - Equity: alerts in 19+ Indian languages bridge the linguistic and digital divide [3].

Wider strategic dividends of indigenisation - Atmanirbharta in critical information infrastructure avoids foreign-vendor dependence, aiding CBRN, terror and border-emergency alerting under MHA [1]. - Positions India alongside the US (WEA), EU and Japan (J-Alert), with export potential.

Yet gains hinge on timely triggering by NDMA/SDMAs, avoiding alert fatigue, and layering CBS with SMS, sirens and community networks.

As a redundancy-rich, indigenous early-warning layer under the Disaster Management Act, 2005, CBS operationalises the Sendai Framework's prevention-first ethos — anchoring a genuinely anticipatory, resilient disaster-response state.
