Imagine from disaster damage statistics
Contribution day and time: 2013/08/19

There is an index called the World Risk Index. The world risk report ranks Bangladesh as one of the high-risk countries in the world in 2019.

Indonesia and Haiti were easy to imagine, linked to the damages caused by recent earthquakes. Previously, there was an opportunity to learn from a land environment perspective about the past major disasters that struck Bangladesh, especially the large-scale cyclone disasters in 1970 and 1991. During a study session at the institution, I leaned the reported number of the casualties caused by the disasters was 500,000 and 140,000 people each. I was surprised to see the large numbers, but I was wondering why these numbers are so rough. When I looked at the table showing the breakdown numbers, I felt, “Oh!”

Building damage, human suffering, and livestock damage are listed. For example, the cyclone disaster in 1991 resulted in 1,630,543 house damage, 140,000 human suffering (dead or missing), and 584,471 livestock damage.

Yes, human suffering seemed to be a rough figure, while house damage and livestock damage were written down to one digit. And when we looked at what kind of country Bangladesh was like such as caste, religion, and livestock.

The background of the numbers, such as meaning, etc., has come into view. Regarding the number of dead and missing people in 1970, there are no accurate figures, and reports from 200,000 to 550,000 people have been reported in various fields.

Day_163: PAR model : Hazard and Vulnerability (3)

As discussed on Day 147, now we are investing the social vulnerability index of the district, sub-district, and village levels in Ayutthaya. To calculate the social vulnerability index, exposure, susceptibility, and capacity data are examined. Notably, the district level of the index is figured out, as shown in Figure 1, using principal component analysis.

(Please enlarge the screen to see the figure well. Darker blue means more vulnerable. The detailed factors of PCA will be explained later. )

Figure 1: Social Vulnerability Index Industrial Complex Area(SVI-ICA) Ref. 1)

Day_147: PAR model : Hazard and Vulnerability

As mentioned above, the district level of the social vulnerability index can be figured out by statistical data. However, sub-district and village levels data are challenging to collect. We also need to understand the capacity is a factor that includes not only hard but also soft countermeasures against natural disasters, as discussed before. Especially, capacity-soft is not stable by time with circumstances and could be changing from time to time. The stats data is not enough to indicate their actual capacities.

Based on the above fact, the capacity assessment is considered to fill the gaps. The capacity assessment method was based on the FDPI project experience.

The population of the target areas is indicated below:

Table 1:  The Population of the Tambons (Source: registration office 2019)

Below is the category (indicators) to measure the capacity.

Table 2: Indicators and Sub-Indicators for Capacity Assessment

The results are as indicated in Figure 2.

Figure 2: Four Sub-District Capacity Assessment 

The findings show the western side and eastern side have a big gap, as you can see in Figure 2.

Figure 3 explains the education and training part is much different among the four target sub-district. The results mean we can monitor and evaluate their progress after we provide education, training, system, or so on there.

Day_147: PAR model : Hazard and Vulnerability

Disaster researchers often refer to the PAR (Press and Release) model to understand the risk.
The PAR model was described in the book “At Risk”. This book is a kind of bible for disaster researchers. Disaster Risk is described as an overlapped area between Hazard and Vulnerability.

The Disaster risk should also consider “Exposure” and “Capacity”. The capacity has mainly two parts, Hard and Soft. In short, Capacity Hard (CH) means tangible factors and  Capacity Soft(CS) means intangible ones. For instance, infrastructure is CH and education is CS. The Disaster risk usually can be identified by the following picture. Figure 1 indicates the above.

Figure 1  Disaster Risk

Using the below equation, disaster risk would be identified.

Disaster Risk = H*E*V/ (CH+CS)

Each factor such as E (Exposure) could be identified by mainly statistic data in the target area.
To do this, the indices can be established. The data to contribute each factor should be carefully examined.
