ISO DIS 22327 circulated for ballot

The Indonesian delegation suggested ISO 22327 as a work item at the TC's 2nd plenary meeting held in Bali November 2015. It was accepted with huge majority vote and now the work has reached the Draft International Standard stage and is available for public review. The title of the standard is "Security and resilience - Emergency management - Guidelines for implementation of a community-based landslide early warning system ".

Landslides are one of the most widespread and commonly occurring natural hazards. The occurrence of landslides may increase significantly due to uncontrolled land use development and human interfere into unstable slopes. In many countries, landslides cause substantial socio-economical losses.

The goal of a community-based early warning system is to empower individuals and communities to act in sufficient time and in appropriate ways to reduce the possibility of injuries, loss of life, and damage to property and the environment.

Landslide mitigation can be carried out both by structural and non-structural efforts. Structural mitigation includes adjustment of slope geometry, slope reinforcement and protection and improvement of drainage system, all of which can be costly. Relocating people is not always a practical alternative. Therefore the most effective disaster risk reduction can be achieved by non-structural mitigation by improving the community’s preparedness through an early warning system.

Demographic, social, economic, and cultural aspects are often left out in early warning systems. This standard offers guidance to promote the role of the community and social aspects in general. Training people to respond to warnings should be followed up by experts/researchers, and by decision-makers at local and national levels.

Key features of ISO 22327

The implementation of a community-based early warning system is consistent with the Sendai Framework for Disaster Risk Reduction of 2015-2030. The fourth priority of the framework emphasizes the improvement of preparedness in order to respond effectively to a disaster, by implementing a simple, low-cost early warning system and improving the dissemination of information about early warning of natural disasters at local, national, regional and global levels.

According to UN-ISDR (2006), a complete and effective early warning system consists of four interrelated key elements:

  1. risk knowledge,
  2. monitoring and warning service,
  3. dissemination and communication, and
  4. response capability.
