Day_100 indicated a human suffering exacerbation process in New Orleans during the 2005 Hurricane Katrina.

The Figure 1 again shows the relationships between the human suffering exacerbation process and social backgrounds with data. Table 1 also indicates the estimated death numbers in some wards.

The total views are indicated in the following Figure 2, 3, 4, and Table 2.
Concerning the population change, New Orleans is the one of the decreasing communities in US. For example, rapid urbanization related matters caused environmental degradation before the disaster. Campanella(2004)mentioned New Orleans became not a sustainable, but a survival city. The lower 9th ward, for example, with regard to the ethnicity, we can see the high black and the African American proportion.  With respect to Income, we can also identify the people living in the Lower 9th ward have lower incomes.

Day_100 : A Human Suffering Exacerbation-Data from Greater New Orleans Community Data Center

The Greater New Orleans Community Data Center (GNOCDC) website was found after the field survey on Hurricane Katrina in Louisiana and Mississippi in 2005. I was so amazed. This is the one of the demographers great contributions to disaster research.

The site provides the information of the pre-Katrina situations by parish and also by ward. This is very useful to examine the social backgrounds of the areas in detail.

The paper on Karina disaster using these data is to explain how human sufferings were exacerbated by the stage with the social background as shown in Figure 2 (Nakasu, 2006 :Sorry in Japanese, however, summary and figures are in English).

The process can be divided into five stages with time such as A) Pre-disaster B) Direct damage C) Social disorder D) Life environment  E) Reconstruction and recovery. Then, these are examined with the social background data (Figure 3).

For example,  1) Pre-disaster stage, I picked up an evacuation aspect to explain the social background of this stage.

Using the GNOCDC database, I could check the possession ratio of the vehicle in some areas.

Figure 4 No Vehicle Available Ratio (GNOCDC)

Table 1 and Figure 4 show the people in Lower 9th ward, one of the most severely affected areas, had a low possession ratio of the vehicle. This can explain so many residents needed to have government help to evacuate and they could not evacuate before the Hurricane hit.

The general social background, such as ethnic groups, household incomes, and others with other stages of examinations will be discussed later.

Day_77 : Historical trends of the damages caused by natural disasters

The damages caused by natural disasters are from human to economy with the development. This is one of the universal and historical trends in the world and within the countries. Mortality numbers of natural disasters tend to be decreasing with national development, but economic losses are the opposite. This is because of urbanization, science and technology advancement, asset values, and so on. This is the same as developing and developed countries’ relationships. Developing countries tend to have high mortality numbers, on the other hand, developed countries are inclined to have high economic losses.

The following tables (little bit old, sorry) which I used to research on Hurricane Katrina in 2005. What you can say about these?

table1

table2

Yes, table 1 indicates almost all high mortality numbers hurricane disasters in the United States are before 1960. On the contrary, table 2 shows almost all high-cost hurricane disasters are after 2000.

Day_16 : GNOCDC

The Greater New Orleans Community Data Center (GNOCDC) website was found after the field survey on Hurricane Katrina in Louisiana and Mississippi in 2005. I was so amazed. This is one of the demographer’s great contributions to disaster research.
The site has the following:
http://www.datacenterresearch.org/pre-katrina/prekatrinasite.html

The site provides information on pre-Katrina situations in a parish. This is very useful to examine the social backgrounds of the areas in detail.
I wrote the paper by using these data to explain how human suffering was exacerbated by social backgrounds (sorry in Japanese; however, the summary and figures are in English).
