TNSMART Aligned with Global Frameworks
TN SMART monitors implementation of strategies to be compliant with
• four priorities set forth in Sendai Framework & Sustainable Development Goals.
• priorities set-forth in Tamil Nadu State Disaster Management Perspective Plan 2018-2030
![Page 28: TNSMART Tamil Nadu System for Multi-hazard Potential](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f6164642d9f7659d2ce00d/html5/thumbnails/28.jpg)
28
Key Strengths
• Role of TNSMART integrated in Policy documents (State
Disaster Management Plan 2018-2030, Policy Note 2018-19)
• Engagement of operational users from State to Village level
in using the system to ensure data flow.
• Innovative institutional mechanism (RIMES Program Unit
Offsite – RIMES Onsite office – CRA-DM Operations) to
ensure technical support and keeping the system up to
date.
• Transparency in DM by providing access of data to public
and media to mainstream risk communication process
• Building trust with all stakeholders through timely outreach
![Page 29: TNSMART Tamil Nadu System for Multi-hazard Potential](https://reader031.vdocuments.site/reader031/viewer/2022020700/61f6164642d9f7659d2ce00d/html5/thumbnails/29.jpg)

Key Strengths• TNSMART will play a critical role in DRR by
• Saving lives by evacuation to safe shelters
• Saving livelihoods – evacuating animals, safeguarding movable assets, advisory to farmers for minimising the impacts (e.g. pruning coconut trees before the cyclone hit to save crops)
• Prepositioning materials & resources for faster recovery process (infrastructure, power, health) and thereby reduce economic costs
• Will strengthen policy making for DRR by continuous
up dation of database and validation of various DRR measures , guidance for DRR investments and minimise impacts of disaster related losses in tune with SENDAI framework

Transfer of TNSMART Technology
❖ India Meteorological Department has decided to adopt the
application at national level to provide Impact Based Forecasting
Services to all the States
❖ RIMES initiated replication in two more States (Odisha and
U.P) and in 9 other countries based on the demand from its
participating countries
❖ Support by World Bank through CDRRP in TN and keenness
to take it forward in other States and other Countries
