Project name: Disaster Risk and Resilience Assessment Framework (DRRAF) and roadmap for Tamil Nadu
Tamil Nadu, a key economic and industrial hub on India’s southeastern coast, boasts a rapidly expanding digital infrastructure. However, coastal districts face severe risks from cyclones, urban flooding, and coastal erosion.
Strengthening telecom infrastructure resilience is vital for ensuring uninterrupted emergency communication, safeguarding economic activities, and enhancing disaster preparedness, particularly in densely populated urban centres and vulnerable coastal communities.
Proactive measures can reduce disruptions and bolster long-term sustainability.

Impact
1
The study revealed that telecom towers in the state face extreme cyclone wind speeds, impacting network stability during storms. This highlights the urgent need for robust tower designs and strategically placed emergency backup systems to ensure resilience.
2
The study revealed that 33% of Tamil Nadu’s telecom towers are in flood-prone areas, exposing weaknesses in drainage resilient siting. Urgent measures like elevating equipment and rerouting cables above projected flood levels are essential for safeguarding network reliability.
3
The study highlights a growing risk of submarine cable cuts from coastal erosion and high-intensity hazards, recommending multiple cable landing zones to enhance redundancy, strengthen resilience, and ensure uninterrupted connectivity in the first-mile network.
