InaSAFE Concept

InaSAFE is free software that produces realistic natural hazard impact scenarios for better planning, preparedness and response activities.

Bengawan Solo – Flood Contingency Plan River Length : + 343.6 km Across 5 Districts : Ngawi, Bojonegoro, Tuban, Lamongan, Gresik Across + 198 Villages Last Flood : April 13, 2013

Bengawan Solo – Flood Contingency Plan Challenges:

• The size of the area - 343.9 km long

• Crossing 5 administrative districts

• No existing hazard map, limited exposure data

Expectations:

• Use real population data – household level

• Produce a dynamic flood model – real time

• Run different analyses for day time and night time populations

• Build an online information system

Bengawan Solo – Flood Contingency Plan Activities:

• Prepared hazard data – using contours & previous flood extent

• Trained scouts – 3 days, 40 participants

• Prepared field survey forms

• Captured 35,000 buildings - (30 fully attributed)

Bengawan Solo – Flood Contingency Plan Activities:

• Ran Flood Impact Function

• Impact on population

• Impact on buildings

• Identified shelter locations

• Recorded evacuation routes

Bengawan Solo – Flood Contingency Plan Results:

• Prepared a more detailed contingency plan with

• higher resolution minimum needs

• evacuation centres

• evacuation routes

• maps

Bengawan Solo – Flood Contingency Plan Lessons Learned:

• The need to be organised for field data capture

• The value of partnerships & community volunteers

• The importance of stakeholder engagement

Challenges for InaSAFE:

• Calculate population based on vector data

• household level detail – age & gender

• real time hazard & exposure

• no assumptions

• InaSAFE users are able to change the value for minimum needs

Makassar City – Flood Contingency Plan Challenge:

• Makassar City experiences annual floods

• 28 villages affected by the January 2013 flood

Aim:

• To update and improve the contingency plan

• To update flood hazard mapping to include flood prone areas

• To update exposure data mapping – OSM field survey

• Obtain other data to support the preparation of contingency plans • people, infrastructure, economic, law and order

• Identify safer places for evacuation points

Makassar City – Flood Contingency Plan Activities:

• Flood Impact Function

• Population affected by age and gender

• Infrastructure affected by type (buildings, roads, telecoms)

• Minimum needs – logistics

• Other analyses

• Landuse affected by type – economic impact

• evacuation centres

• evacuation routes

Makassar City – Flood Contingency Plan Lessons Learned:

There is more to contingency planning than just using the software

• Partnerships

• Stakeholders

• Engagement and ownership at the community level

It is easier to improve on an existing contingency plan than to prepare the first one. The need has already been identified and the stakeholders are willing to work on improvements.

Challenges for InaSAFE:

• Calculate the percentage of an area affected

• Present the results in a different way

Volcano Impact Assessment Challenge:

• A direct request to AIFDR from BNPB to determine if InaSAFE is fit for purpose

• To get the numbers ‘right’

Aim:

• To assess the number of people within a specified radius of a volcano

• To assess the number of people in each hazard zone

• To quantify the results using AsiaPop and Indonesian census data BPS
