Preparedness phase: early warning

01.09.2020

Improvements to preparedness, particularly through early warning schemes, save lives. However, they should come from trusted sources, such as the national entity for monitoring and early warning. For hydrological and meteorological events, the national meteorological organization is in charge of issuing those alerts. For instance:

Studies of how people received information after the Tōhoku earthquake and tsunami showed that in disaster-prone areas information should be issued using varied media, both auditory and visual. Warnings can come from sirens, loudspeakers, digital signs, television broadcasts, radio broadcasts, cell broadcasts, location-based phone calls, and SMS messages and messages to smartphone apps. A system in Sri Lanka dependent on mobile phones and special-purpose alarms that provides for several of these media, with various attendant problems, is described by Wickramsinghe (2011).

The Common Alerting Protocol (CAP) is a well-established mechanism for ensuring that warnings transmitted by different media are substantially similar (WMO 2012). The warnings are composed by an official authority and passed to issuers of the warning in the CAP format. The warning issuers then simply run programs to convert the warnings to the formats used by their media (WMO 2013). The Federation for Internet Alerts (FIA) has developed Public Warning Design Guidelines for FIA Messaging (FIA 2015). This is a useful starting point when considering formats of warnings in other contexts besides Internet use.

In the United States, for example, the Wireless Emergency Alert (WEA) system is a tool for authorized federal, state, and local government entities to geographically target presidential, imminent threat, or AMBER Alerts (to search for missing children), to the mobile devices of the users of the mobile providers participating in the WEA system. Sending alerts in the WEA system begins when an authorized government entity sends a WEA alert message using CAP to the alert aggregator, operated by the Federal Management Agency Emergency (FEMA), through a secure Internet-based interface. In this interface, the alert message is authenticated, validated, and subsequently delivered to the FEMA Alerts Gateway. At the FEMA Alerts Gateway, the alert message is converted to a Commercial Mobile Alert, to make it readable by mobile devices that support the WEA system. The alert message is then broadcasted via a secure Internet-based interface to the alerting gateway of the participating mobile providers for distribution to mobile customers via mobile transmission (FCC 2019). In the United States, these types of emergency alerts using CAP can also be distributed to radio and television stations and cable television channels, among other media, who can then retransmit such information to local communities across the country.

Traditional techniques for warning people, such as showing pictures, raising flags, visiting houses, blowing horns, shouting, banging, and whistling are important, too, especially among the poor and older people (IFRC 2012). With all techniques, whether electronic or traditional, women need to be involved properly; for instance, in Bhutan women have been said to prefer the use of mobile phones to sirens for early warning, because they can then be reached in their houses as well as in the fields (ICIMOD 2016).

Early warning systems might well be integrated into wider schemes for government-to-citizen (G2C) communications. Nonetheless, local knowledge remains useful, especially if official schemes are not universally available or fully maintained. For instance, in one project in Nepal, villagers have been encouraged to use mobile phones to warn others downstream about probable floods (Giri and Malakar 2011). Difficulties arise if local knowledge is discredited, for example, when a family moves possessions because of a warning about floods that then proves to be unjustified.

The ICT regulator should make regulatory provision for using ICT services and platforms for warning the public. For instance:
