Typhoon Haiyan Recovery Program

Overview

3

3,000 Households whose

shelters were affected by

Typhoon Yolanda

Conditions:

– Urban, dense

– informal settlements,

with some private

landowners

– highly vulnerable to

flooding, tsunamis,

typhoons, storm surges

Typhoon Haiyan Recovery Program

Overview

Goal: Households affected by super typhoon Yolanda live in resilient communities

Damage caused in coastal area by the Typhoon. Nov. 2013. Beneficiary constructed a new house incorporating “Build Back Better” techniques. July 2014.

Household Level Support

• Shelter, toilet, water

connection, and grey water

drainage assistance

• Paralegals to help with civil

document recovery

• Trainings:

– Build Back Safer construction

practices

– Hygiene Promotion

– Land, housing, and property rights

– Protection issues

– Family preparedness

• Urban DRR trainings

• DRR Contingency and

Evacuation Plans

• Drainage

• Solid Waste Management

• Barangay Infrastructure

Why did CRS decide on using an UAV and

GIS?

• Saves money (vs. land surveys)

• Processing time is much faster

• No map was available

7

– Land Tenure mapping- proving people’s title/ownership

– Project participants’ buy-in thru participatory uses of maps

– Improved settlement design to create healthier, safer communities

– Create contour map which is helpful for infrastructure projects

– Shows how to open a neighborhood for evacuation routes

– Quality, data-linked images improve communication for donors and

for internal decision-making

What were the expected uses?

8

Considerations prior to using UAV

• Project participants’ privacy/ethical concerns

• Proper approval channels for use of UAV thru LGU, barangays, airport..

• Buy vs. hire

– Who operates it?

– Who maintains it?

– What are the rules and regulations?

– Who repairs it?

Working with SkyEye

• Philippines-based

• Government approved, managed the

regulations and bureaucracy

• Operation and maintenance of UAV

• Process raw data into image

9

Technical Info on SkyEye

• UAV type: SkySurfer Drone, fixed wing

• Flight duration: 1 hour

• Type of software used for georeferencing:

commercial and SkyEye owned.

• Other clients: DENR, Del Monte Philippines

Inc. , First Asia Institute of Humanities and

Technologies, Conservation International

Process of Developing the Baseline Maps:

Household Survey

11

Process of Developing the Baseline Maps:

Use of GPS + Fieldwork

12

Process of Developing the Baseline Maps:

Statistical description and Spatial Analysis

13

DATA DESCRIPTION USE SOURCE

Road Types of road: primary to footpath

Accessibility assessment , Evacuation route

OSM

River/Drainage Classified into river, stream, canal

Proximity analysis (settlements to waterways)

OSM

Elevation/ Contour

Based on ASTER 30m GDEM Scale is small, but useful for larger spatial context visualization

Ministry of Economy, Trade, and Industry (METI) of

Japan, NASA

Graded Damage Map Building Footprint-level grading: destroyed, highly affected,

moderately affected, possibly affected (Nov 14. 2013)

Comparison with registration data European Commission – MapAction Copernicus

Barangay Boundaries

Barangay divisions based on Comprehensive Land Use Plan

2012-2021

Jurisdiction over space; resource management

Tacloban City Planning and Development Office

Process of Developing the Baseline Maps:

Spatial Data from Secondary Sources

14

Process of Developing the Baseline Maps:

Mapping during Community Workshops

15

Process of Developing the Baseline Maps:

Verification of barangay boundaries

16

Maps with Community Input

17

Maps with Community Input

18

The red dots represent the

GPS-generated locations of

the surveyed households,

while the squares represent

the buildings or structures.

Each point is associated with a

set of information in tabular

format (right of image), which

comes from the CRS

Database.

Process of Developing the Baseline

Maps: Geo-referencing the Urban

Shelter Database

Identifying each structure with a particular household

Utilizing the UAV image, each beneficiary can be linked to a specific household structure

Process of Developing the Baseline Maps:

GIS-linked Households

20

• Disaster Risk Reduction plans and evacuation routes

• Analysis of densification and relocation

• Contour map for infrastructure projects

• Measure progress of project/ household beneficiaries:

• Efficient monitoring of progress of household beneficiaries in the

use of their conditional cash grants

• Donor reporting tool: Progress of the relief and recovery efforts

can be mapped visually and in real-time providing different

donors and stakeholders with concrete evidence of development)

• Internal decision-making tool

– Area that is not progressing quickly-> more support/visits from

Community Organizer, Engineer, foremen

Next steps in the use of UAV and GIS

• Geospatial imagery and analysis in support of DRR activities

– Expansion into a another part of urban Tacloban

• Site planning

– Water and sanitation analysis

• Septic tanks design and infiltration

• Water connections with LMWD

• Lay-out of the houses and infrastructure to maintain proper easements from roads, creeks, high tide mark

• Digitalization in the cloud for media and communications purposes.

– More visual information sharing

• Internal decision-making tool

– Knowledge retention of Build Back Safer or Hygiene Promotion trainings-> improve capacity of staff giving training and re-train with better modules

26

Challenges and Lessons Learned

• Technical staff are needed to know how to optimize the use of the

maps

• Outsourced Community Action Planning process and done in a short

time-frame

• Short term technical consultancy led to various opinions on what the

maps should be used for

• Problems with iPad GPS

• One point vs four points digital footprint of shelters

• Community use and buy-in
