Dangerous Delays and Fallible Fire Alarms

Save the Children and Oxfam released a joint report today entitled "A Dangerous Delay: The Cost of Late Response to Early Warnings in the 2011 Drought in the Horn of Africa". The report argues that early warning systems performed, but decision makers did not respond to them. In an interview Justin Forsyth the head of Save the Children UK likened the situation to an alarm bell that had a very delayed effect. A lot of people were harmed by the delayed response and the cost of dealing with hunger and malnutrition was much higher than if it had been addressed earlier.

So why the delay? Using Forsyth's analogy, either policymakers did not hear the alarm, did not trust it, or although hearing and believing the alarm, they simply could not respond to it quickly enough. The report makes some good recommendations about amplifying the alarm (via the media and building up capacity of those to communicate the significance of the alarm up the decision chain). It also makes good recommendations about helping people respond to it more quickly once they believe it (emergency response funds, insurance, greater joint programming between development and humanitarian groups).

The one area that the report is relatively silent on is whether the policymakers believe the signals. The report focuses on the case where the signals were right and outlines the cost of ignoring them, but policymakers might argue: what about the costs of acting when the signals were wrong?

As researchers, we should be analysing, ex post, the frequency with which the early warning signals get it right. If we can attach a probability to the predictive power of the signals, then when the next signal goes off policymakers can better assess the risks of responding to a non crisis against the risks of responding late to an emerging crisis. In other words, how often will the signal get it right?

It's not pretty, but I would not be surprised if this is the kind of calculation that is often made.

I think that's a very good point to make and you make it well. How many of these types of early warning systems exist that would be available for analysis?

Lawrence Haddad said...

thanks Sam...I don't know how many but I would imagine it is not too difficult to do this.... construct a database of warnings, find out what happened afterwards in terms of actions spurred and the depth and scale of the disasters that actually occurred. It might even be something that FEWSNET and others do on a routine basis for their own learning...but I have never seen such a study.

Have you seen the recent paper by Simon Levine and others on early warning systems in the Horn? Very relevant to this discussion, and makes some interesting points about system failures...

That was very rational. When deciding to put up security cameras,
determine first the areas you’d like monitored. This gadget could be quite expensive
if you’d put up one unit in every corner of the house. The key to such problem is proper
angling. Home safety is paramount, that’s why it is really good news that home security
cams are more affordable now. Having a secure home wouldn’t then be at all impossible
for some people.

Sometimes it is prudent to install a back-up alarm. In case one fails and I don't see both alarms failing simultaneously. In our house we have two silent security alarm systems perth.

I regularly call a security locksmith to check our lock systems so we can prevent accidents. I always make it sure that all lock devices are in one place and every department have duplicates.

It's bothering to hear that the people who are named as the community's public servant are ignoring this kind of issue whereas they should in turn, address to this kind of concern especially it concerns the overall safety of the "Public." I say, these officials should better straighten up and fix the problem to avoid fire crisis and the likes from jeopardizing the public's at ease living.
