GLobal IDEntifier Number (GLIDE)
What is a GLIDE number?|
Accessing disaster information can be a time consuming and laborious task. Not only is
data scattered but frequently identification of the disaster can be confusing in
countries with many disaster events. To address both of these issues,
Asian Disaster Reduction Center (ADRC) proposed a globally common
Unique ID code for disasters. This idea was shared and promoted by the Centre for Research
on the Epidemiology of Disasters (CRED) of the University of Louvain in Brussels (Belgium),
OCHA/ReliefWeb, OCHA/FSCC, ISDR, UNDP, WMO, IFRC, OFDA-USAID, FAO, La Red and the World Bank
and was jointly launched as a new initiative "GLIDE".
How is the Number determined?
A GLobal IDEntifier number (GLIDE) was issued every week by EM-DAT at CRED for all new disaster
events that meet the EM-DAT criteria (see http://www.cred.be) from 2002-2003. Of course, Ways
to cover disasters that fall out of EM-DAT criteria was being sought and would be provided in
due course. And from the beginning of 2004, "Automatic GLIDE Generator" begins to generate new
GLIDE for all new disaster events. The components of a GLIDE number consist of two letters to
identify the disaster type (e.g. EQ - earthquake); the year of the disaster; a six-digit,
sequential disaster number; and the three-letter ISO code for country of occurrence.
So, for example, the GLIDE number for West-India Earthquake in India is: EQ-2001-000033-IND.
How can I use it?
This number is posted by the above organizations, on all their documents relating to that particular
disaster and gradually other partners will include it in whatever information they generate.
As information suppliers join in this initiative, documents and data pertaining to specific
events may be easily retrieved from various sources, or linked together using the unique
GLIDE numbers. The success of GLIDE depends on its widespread use and its level of utility
Today, users all over the world can pick up the GLIDE number from the homepages of CRED,
ReliefWeb and ADRC. ReliefWeb, La Red and ADRC have prepared a specific website
http://www.glidenumber.net/ to promote GLIDE.
Being in its experimental phase, the group encourages to visit this website and welcomes
comments or suggestions.
How to Join
GLIDEnumber.net, and the GLIDE generator are intended to facilitate linkages between records
in diverse disaster databases.
Glidenumber.net makes no claim as to the statistical
accuracy of the GLIDE generation system, and discourages the use of the data on this
site for secondary analysis.
- The GLIDE database is easily searchable by many criteria.
- Information in the GLIDE database may be presented in many forms, including tabular and graphic forms.
- Anyone can register at
- You can subscribe to receive instant or periodic info about recent disasters.
- Your personal info will never be distributed or sold
