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. Especially, the district level of the index is figured out as shown in Figure 1 using principal component analysis.

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

The district level of the social vulnerability index can be figured out by statistical data. However, sub-district and village level data should be difficult to collect such data. Based on the fact, the capacity assessment is firstly conducted to the target four sub-districts as indicated in Figure 2. The capacity assessment method was based on the FDPI project experience.

Figure 2: Four Sub-District Capacity Assessment 

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

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

The detailed examination will be explained later.

*Exposure, Susceptibility, and Capacity data list will be shown later. The theoretical frame is base on the PAR model. The below book can be referred.

At Risk: Natural Hazards, People’s Vulnerability and Disasters

**This is the baseline research for the SATREPS project.

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.
