WHY GIS?

• No other technology synthesizes and displays
  complex agricultural, natural resource,
  environmental, demographic, and socioeconomic
  information, and relationships as completely or
  intuitively as GIS.

WHAT IS A GIS?

• Geographic Information System (GIS) is a
  computer system used by PEOPLE capable of
  assembling, storing, manipulating and displaying
  geographically referenced information.

E.C. Godilano, Ph.D.

GIS Work on Themes

• One of the strengths of GIS is the capability
  to separate information in layers, and then
  overlay or compare multiple feature layers of
  information. A user can then analyze the
  relationship between the layers.

• GIS allows us to view, understand,
  question, interpret, and visualize data in ways
  simply not possible in the rows and columns of a
  spreadsheet.

Beautiful and interesting maps provide better
decision making tools and analysis and make a
difference in our world.

THE PHILIPPINES A RECORD HOLDER

• We lead the World in the types and frequency of
  natural disasters.
• We ranked 4th in the number of people killed or
  affected by floods, tsunamis, typhoons,
  landslide, earthquakes, volcanic eruptions and
  man-made disasters.
• We have been chosen by aid organizations as a
  "laboratory" for new approaches in disaster
  mitigation. (PNRC, (2003)

BACKGROUND OF THE STUDY

• The rainfall that occurred in Leyte and Surigao
  was 600 and 700 percent higher than the 35 year
  average.
• The area was mostly planted to coconuts.
• We contend that there was no deforestation or
  illegal logging in the area.

E.C. Godilano, Ph.D.
10
WHAT CAUSE(S) THE TRAGEDY?

• Illegal logging?
• Deforestation of mountains and watersheds?
• Land conversion?
• Freak weather?
• Global climate change?
• Government neglect?
• All of the above

OBJECTIVES

• Identify parameters that will geographically
  locate disaster prone areas at the national,
  regional, and local levels.
• Develop a GIS framework as a tool in disaster
  prediction and ANR management.
• Identify hotspots using GIS technology
  (tactical plans).

12
OBJECTIVES

• Generate statistics for national and local
  government (strategic plans).
• Identify thematic areas of convergence
  activities.
• Provide cost effective measure in disaster
  prediction and management.
• Improve local governance of disaster prone areas
  using GIS technology.

SUMMARY
DISASTER ANALYSIS IS A FUNCTION OF
E.C. Godilano, Ph.D.
29
RECOMMENDATIONSLocal Level

• Provide LGUs with rain gauges as an early warning
  instrument.
• at 1000-1500 accumulated rainfall start
  evacuation
• At 1500-2000 accumulated rainfall, disaster had
  occurred initiate search and rescue operations
• Update the Provincial Physical Framework Plan
  (PPFP)
• Update the SAFDZ and CLUP
• Institutional and capacity building in using GIS
  in LGUs
• Community awareness and participation
• Integrated planning and management

E.C. Godilano, Ph.D.
30
RECOMMENDATIONSNational Level

• 1. Detailed analysis using RS, other data, and
  ground truthing of results
• 2. Priority implementation of land use policy and
  conversion in the identified hotspots
• 3. DA-DENR-NDCC-LGU partnership in project
  implementation in identified hotspots
• 4. Precision disaster management
• 5. Increase budgetary allocation for R and D

E.C. Godilano, Ph.D.
31
RECOMMENDATIONSNational Level

• 6. Creating an interagency taskforce for disaster
  prediction and management
• 7. Adopt the WATERSHED approach in ANR planning
  and management
• 8. Establish the NGII and NGICH
• 9. A unified project proposal
• 10. POLITICAL WILL

RECOMMENDATIONSDA-DENR-NDCC-LGU

• Greater role of the DA in disaster management.
• The DA? should take the leadership as 79 percent
  of the hotspot area is under its jurisdiction.
• Using geospatial technology (GIS, RS, and GPS) as
  a decision support tools in local governance of
  programs and projects.

CONCLUSIONS

• GIS and technology can be a catalytic tool that
  could guide policy makers in disaster prediction,
  mitigation, and ANR management.
• Now we know the why, when, and where landslide
  could occur and who will be affected.

E.C. Godilano, Ph.D.
36
CONCLUSIONS

• Use in local governance, GIS technology can
  leapfrog the Philippines in the 21st century and
  the disaster in Leyte and part of CARAGA can be a
  thing in the past
• NEVER AGAIN shall our people live in fear of
  being buried alive in a landslide.
