Marinduque

4th Income Class
Marinduque extends about 170 km, south of
Metro Manila between the Bondoc
Peninsula at the eastern portion of Luzon
and Oriental Mindoro. Bounded on the
North by Tayabas Bay, NE by Mongpong
Pass, SE by Tayabas Strait and Sibuyan Sea at
the South.
agriculture and
fishing is the
primary industry
•
It is estimated that almost
80% of the island has ore
deposits of various metallic
and
non
metallic
substances (gold, copper,
iron, manganese,
marble
guano, etc).
Almost 1/4 of the total land area
is categorized as
timberland/forest land…..
And this province is ranked as
the 3rd most denuded forest
in the country in 2005 (Source:

The island is within the
Typhoon belt area.
Marinduque is also categorized as the 7th hazard prone province in the country.
Preliminary study shows that Marinduque is susceptible to various hazards…..
Importance of CCV Mapping
 But while it is important to identify the susceptibility level of
a particular area, it is also crucial to assess or determine the
vulnerability of a community or barangay.
 Equally important is to measure and determine their
capability and capacity to bounce back after the calamity.
- With the technology that we can use to map the level of
susceptibility, it is vital to consider the socio economic
condition of the community, in particular, the human
development factor, the population and the livelihood at
risk vis-à-vis the infrastructures and the institutions
that are in place.

Vulnerability Index
Objectives of the Study
The study aims to:
1. identify, the Climate Change Vulnerability Index of each barangay in
every municipality, down to the HH level.
2. determine the readiness and resiliency-level of the LGUs during
calamities and in a changing climate.
The data generated through this system will aid local government units
(LGUs) in mainstreaming the Disaster Risk Reduction Climate Change
Adaptation (DRR CCA) in our local development planning particularly
as reference for the province’s Disaster Risk Reduction and
Management (DRRM) planning.

Santa Cruz. These areas are not only exposed to landslides and
erosions but to floods, as well.

The flood plains of Boac were further worsened by the 1996 Marcopper
Tapian Pit spill. Likewise, in Mogpog River, the river bed elevation is higher
than the barangay built‐up area due to the continues siltation from the
overburden of the abandoned Marcopper stockpile.
Located in the North
eastern part of the
province, Sta.Cruz is
hilly and mountainous
with slopes ranging
from 18 percent and
above. More than half
of the 55 barangays in
Sta.Cruz are coastal
barangays. There are
ongoing reforestation
projects
in
some
barangays
of
this
municipality, e.g., the

…… Boac, which is a 1st class municipality, has available health workers and barangay health facilities that can cater to the population in the area. It may not yet be
adequate, but compared with the other municipalities in the province, it is better equipped and can address these particular service and facility requirement in the
barangay to at least moderate the impact of CC.

Biga,
Brgy. Biga,
Sta.Cruz
 Among the 218
barangays in the
province, Brgy. Biga
in Sta.Cruz has the
highest CCVi having
0.635.
 Brgy. Biga is a coastal
barangay, located at
the NE portion of the
province; facing
Tayabas Bay and is
open to northwest
monsoon.
The Exposure Index of Brgy. Biga is 0.719
 Of its total land area of 152.914 hectares, 74.0 hectares have high
susceptibility to landslides and 64.0 hectares are susceptible to
floods due to surface run off and during high tides.
The Sensitivity Index is 0.501
 More than half of the 360 HH population of Brgy. Biga are engaged
in fishing and crops farming. Large portion of the barangay is hilly,
and rice production is rainfed. (farmers practice upland farming)
 The population density of Biga is 235 persons per sq.km., higher
than that of the province’s and slightly lower than that of the
municipality’s pop. Density.

Vulnerable Members of the Population-
Location of households with senior citizens
60 years old and above, Brgy. Biga, Sta. Cruz, Marinduque
Of the total population of Biga, 12.78 per
cent are the Elderly, those whose age are
60 and above; 38.06 percent are
children; and 1.9 percent are Persons
with Disabilities.
The Adaptive Capacity Index of Brgy. Biga, Sta.Cruz is 0.666, the highest among
the 218 barangays in the province
 More than half of its household population are living below the poverty
threshold.
 Only 100 meters of the barangay is concrete, the remaining stretch are either
earth of gravel roads that easily scour and wash out during extensive rains and
floods.
 For a population of 360, there are only 3 Barangay Health Workers, giving us a
health worker to population ratio of 1:120, and no barangay health station.
The nearest BHS is more than 2 kms. away; and the next higher health facility
is 7 kms. away from Biga to Barangay Malabon, passing thru rough roads.
 The BDRRMC’s average DRR fund (Brgy DRRM fund + municipal DRRM fund)
annually is Php 66,000 or Php 184.00 per person.
 The evacuation center being utilized is the Barangay Hall/Primary School
which may not be adequate to accommodate the potential population who
are at risk during extreme weather condition.
Conclusion
1.The impact of climate change is greater to those areas that are highly prone to
landslides and floods.
2. The most vulnerable to disasters are the small islands.
The small islands does not only face a multitude of hazards, but also the grim
possibility of being isolated from the mainland during extreme weather condition
like typhoons…..
(National Conference on Disaster Risk Reduction and
Climate Change Adaptation in Small Islands in the
Philippines sponsored by Christian Aid, EC and CARE)
3. Given the current environmental condition of the province, such as having the most denuded
forest and categorized as hazard prone province, it is of high importance and priority to
strengthen the adaptive capacity of the community or LGUs.
Basic Policy Recommendation
The Vulnerability Risk Mapping using CBMS shall be used as reference or
guide in mainstreaming the Disaster Risk Reduction and Climate Change
Adaptation (DRR CCA) Plan to the local development planning processes,
from the national level to provincial down to the municipal and barangay
level. The result of the CCVi is an important input particularly in the
prioritization of programs/projects for possible funding assistance from
the national government thru the NDRRMC and organizations whose
priority thrust is to address issues and concerns related to DRR CCA.
