New Tools, New Science, and New Opportunities in
Agriculture and Resource Management (ANR)

4WHY GIS?
- No other technology synthesizes and displays
complex agricultural, natural resource,
environmental, demographic, and socioeconomic
information, and relationships as completely or
intuitively as GIS.
USDA, January 2002.

5WHAT 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.
6GIS 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.
E.C. Godilano, Ph.D.
7- 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.
E.C. Godilano, Ph.D.
8THE 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)
E.C. Godilano, Ph.D.
9BACKGROUND 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.
10WHAT CAUSE(S) THE TRAGEDY?
- Illegal logging?
- Deforestation of mountains and watersheds?
- Land conversion?
- Freak weather?
- Global climate change?
- Government neglect?
- All of the above
E.C. Godilano, Ph.D.
11OBJECTIVES
- 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).
12OBJECTIVES
- 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.

28SUMMARY
DISASTER ANALYSIS IS A FUNCTION OF
E.C. Godilano, Ph.D.
29RECOMMENDATIONSLocal 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.
30RECOMMENDATIONSNational 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.
31RECOMMENDATIONSNational 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
E.C. Godilano, Ph.D.
32Watershed Concept in ANR Planning and Management
E.C. Godilano, Ph.D.
33RECOMMENDATIONSDA-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.

35CONCLUSIONS
- 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.
36CONCLUSIONS
- 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.
