Disaster RiskReduction (DRR)

requires accurate andup-to-date spatial

information as well as GITHRAwell-trained expertswho can provide this

information.

The GITHRA project is a concerted, ambitious

and unique attempt to build capacity on theapplication of modern Geo-IT for Hazard Risk

Assessment (HRA) and Disaster RiskReduction (DRR).

Staff of the Vietnamese Ministry of Agricultureand Rural Development (MARD) and its

Vietnam is located in one of the storm

centers in the world, in one of the regionsmost hit by natural disasters and in one of

most vulnerable regions when it comes to

climate change impact.

The Asian Development Bank gives toppriority to natural disaster control programs

to the Government of Vietnam with theEmergency Rehabilitation of Calamity

Damage Project (ERCDP).

An essential component of the assistance is

be able to contribute to DRR efforts by

providing relevant and accurate spatialinformation and to carry out complex spatial

Hazard Risk Analyses. This should contributeto a better understanding of disasters and

support the development of mitigation options.

and implement DRR measures. Therefore

the ADB initiated the Technical Assistance(TA-7220-VIE) package Geo-information

Technology for Hazard Risk Assessment

(GITHRA) for the Vietnamese Government.

Disasters are spatial phenomena and theassessment of areas under high risk

requires the use state of the art Geo-IT

technologies like Geographical InformationSystems (GIS) and Remote Sensing (RS).

GITHRA aims at buildingcapacity in the use of

The methodology for Multi-Hazard Risk

Assessment in Vietnam has been fully integrated

in a set of two books that form the core of thetraining materials:

Yen Bai Case Study SiteThe city of Yen Bai was selected as

a case study site to test theapplicability of the MHRA

methodology developed in GITHRAin the Vietnamese context. Yen Bai

is the provincial capital of the

rovince with the same name. The

The Yen Bai dataset is added to the

training package and forms part of theexercises and the Final Assignments.

Examples of the final assignments done

by the GITHRA participants:

1) Flood hazard assessment in Yen Bai .old center is located on the

floodplain of the Red River and thenewly developed parts encroach

into the surrounding hills.

Yen Bai suffers frequently from alluvial

flooding from the Red River, flash floodsfrom the tributaries coming from the hills

and landslides due to slope cuts. In 2008

2) Flood damage to houses and people3) Economic flood loss assessment

4) Shelter location assessment in YenBai for flood disasters

5) Flood risk preparedness

the city was severely flooded andexperienced numerous landslides due to

typhoon Kummari.

For the case study a geo-spatial database

was constructed that includestopographical information, elevation data,

high-resolution satellite imagery, landcover a a, e c. un ng

automatic meteo-stations were installed aswell as water-level monitoring station at

various locations in the study area. Thesestations will provide temporal informationon rainfall and stream runoff which will be

vital for future flood hazard analyses. Alsogeo-technical data relevant for slope-

field- and laboratory tests.
