There is no electricity available in the village, but most households depend on solar panels for lighting and for charging mobile phones' batteries. Zong is the only mobile network whose signals are occasionally available in the region. There are radio sets present in almost every

With reference to the Section "Pilot Coastal Communities" following information was collected relevant to data on nontrivial, that is, significant and dependent of surroundings of commun‐ ities studied and data on trivial, that is, insignificant and independent to surroundings. The

The ultimate goal of an effective, warning system is to have the most effective coverage for the most affordable price or cost. Therefore, it is very critical to properly evaluate the structure and local needs of an area before designing and implementing an effective warning system.

household and people listen to news broadcasted on BBC Urdu and FM Gwadar.

The information about the location of a community and audiences is very crucial in identifying the type(s) of method and hence the system(s) to be used—for both dissemination and notification of a warning to an area.

The information about population concentration directly links with the location of audience; indoor or outdoor. The type of construction gives an idea about effective penetration of an alert to a particular area. A careful analysis of both parameters can give a better selection of an information dissemination system in terms of effectiveness of an alert.

**Figure 15.** Telecommunication networks availability.

The graph provides an analysis of availability of types of phone coverage in the area. It can be noted that although coverage is partial mostly (80%), but GSM phones were available in all 10 villages as compared to 10 and 20% and respective availability of landline (V phone Pakistan Telecom Wireless phone) and 3 G services in the surveyed villages (**Figure 15**: Telecommuni‐ cation Networks Availability). But these mobile networks are partially accessible in most of the villages like weak or no signals in the middle of the island and inhabited area. Villagers have to reach out at certain locations for a certain commercial GSM network. Satellite phones can be used in all 10 surveyed villages; however, none of the community member is presently using this communication mode because of its very high cost.
