Japan’s Experience for DRR&

Linking DRR to Sustainable Development by DR2AD Model

Why Japan can dedicates on DRR

• Japan is the most natural hazardous country in the world.

• In the same time, one of the most technology oriented developed country.

• How Japan coexists or conquereDisaster & Development

1

Japan case

• More than 50% of population, living in the flood plain

• More than 75% of whole asset located in the flood plain

• Without any structure measures, Japan can not survive

• How to prepare excess flood or earthquake

2

Up to 15th Century, Tone River crossed the Kanto Plain from north to south and flew into Tokyo Bay

From 1594 to 1654, Tone River was connected to Pacific Ocean by eastward channel

・After the flood in 1910, flood control measures in upper and middle reaches has changed from “flood control allowing inundation” to “sequential levees confinement”

・After this change, the maximum discharge in the Tone River Channel has increased, which became the main challenge of flood control in Tone River Basin

How to invest today?Principle for

low regret investment

13

• Population of damaged area of 3 prefectures,1km from coast is 460,000, 3km 1.0million, 5km 1.5million

• Total causalities were around ≒18,000

• 460,000 residents lived in the tsunami affected area so that evacuation ratio can be estimated more than 96 %

• This high evacuation ratio achieved by legend transmission, by Tsunami Early Warning System and by evacuation drill effort

• 65% of casualties were aged people, over 65 y.o.

Tsunami Evacuation Situation in general

96%> evacuated !!

For the CBDRM project, this is successful case

14

More than 97% evacuated successfully,but local economy was completely destroyed.

Can we say this “resilient”?We need more investment

to prevent disaster

Building the resilience of nations and communities to disasters

The integration of disaster risk reduction into sustainable development policies and planning

Development and strengthening of institutions, mechanism and capacities to build resilience to hazards

The systematic incorporation of risk reduction approaches into the implementation of emergency preparedness, response and recovery

much cheaper than recovery

How to convince & mainstream DRR?

Need to show the evidenceto “political leaders”

• Economical Model which can measure – GDP change

– income differential and Gini coefficient change in Lorenz curve

• With & Without DRR investment

• Philosophy from Japanese experiences “DRR investment Account for Development

21

JICA developed Dynamic Stochastic General Equilibrium Model to show the effectiveness of DRR investment

MDG Targets & Indicators exemplified by DR2AD

Targets Indicators Exemplified by DR2AD Model

Target 1.A

Halve, between 1990 and 2015, the proportion of people whose income is less than $1 a day

1A1 Population below $1/day, %

◎It is possible to calculate the expense of each person except the number ofpeople per household, it is possible to calculate the indicator of expectancy inthe “First Edition”.

1A6 Poverty gap ratio at $1/day, %

◎It is possible to calculate the indicator of expectancy in the “First Edition” byusing the rate of poverty or the Gini coefficient.

1A7 Poorest quintile's share in national income or consumption, %

◎It is possible to calculate the expense of each person by income level it ispossible to calculate the indicator of expectancy in the “First Edition”.

Target 1.B

Achieve full and productive employment and decent work for all, including women and young people

1B1 Growth rate of GDP per worker, %

◎It is possible to calculate the growth rate of GDP, it is possible to calculate theindicator of expectancy in the “First Edition”.

1B2 Employment-to population ratio, %

○

It is possible to estimate the growth of the population, it is possible to calculate the indicator of expectancy in the “First Edition” if it is feasible to set up the distribution of employees in the lowest level of income according to the age and the population.

1B5 Proportion of workers living below $1/day, %

○

It is possible to calculate the amount of the expense of each person, it is possible to calculate the indicator of expectancy in the “First Edition” if it is feasible to set up the distribution of employees living below a dollar a day in the lowest income level.

1B6 Proportion of own-account and contributing family workers in total employment

△If the model of the industrial structure is classified in detail, it can be feasible to calculate the indicator of expectancy by improving the model.

Target 1.C

Halve, between 1990 and 2015, the proportion of people who suffer from hunger

1C3,4 Population undernourished,

Target 2.A

Ensure that, by 2015, children everywhere, boys and girls alike, will be able to complete a full course of primary schooling

2A1 Total net enrolment rate in primary education

◎It is possible to calculate the indicator of expectancy in the “First Edition” because the model is capable of taking account of human capital.

2A10 Literacy rate between 15 and 24 years old, %

○Although it is hard to correlate the level of age with the , it is possible to calculate the indicator of expectancy in the “First Edition” if it is feasible to set up the distribution of the literacy level according to the social level.

What happened after HFA

• Most of donors concentrated to E/W

• Most of donors escaped from challenging structure measures , like reservoir system and so on.

• All donors looks like NGO or amateur for DRR

• Where are the professional confident activities?

• JICA continuously supporting to reduce the risk
