Disaster information systems of most local governments pursue accurate, rapid, and location-specific transmission of information to residents. This approach has generated overdependence of residents on local governments. The double bind theory describes the cause of overdependence as follows. When evacuation orders are repeatedly issued, they begin to take on a meta-message (“Evacuation will be held after an evacuation order is issued.”). Because residents wait for an evacuation order, actual evacuation may be delayed. In response, the government tries to improve its disaster information system, resulting in “overprotection” of overdependent residents. Thus, the problematic relationship between overdependence of residents and overprotection by local governments, is formed. This paper aims to suggest a solution using the case of community-based disaster risk reduction committees in San Pedro Masahuat Municipality, El Salvador. When tropical depression 12E hit the area in 2011, those committees monitored precipitation and river water level and made the decision to evacuate, responding without overdependence on the government. Practices of the committees, including sharing information among communities, unintentionally canceled the effect of the meta-message which led to overdependence. Those practices were extensions of normal community practices such as the management of seeds for farming. Hence、 the key to solve the double bind situation is not only to implement community-based disaster-related practices but also to strengthen these practices for solving daily community problems.
