9. Social Environment
• population is primarily composed of
Ilocanos, Ibanags, Yogads and Gaddangs
• ethnic communities of Agtas and
Dumagats can also be found at the
eastern coastal towns of the province
• about 1,550 hectares area for inland fish
production
• there are still a number of untapped
freshwater resources—lakes, swamps,
rivers and streams—that can be utilized as
potential fish production areas
• wood industry and mining operations put
into halt in favor of environment protection
• agricultural production and eco-tourism is
seen to redefine the new developmental
road map for the province

DIVILACAN
PALANAN
DINAPIGUE
• there are four coastal municipalities located at the
eastern side of the province facing the Pacific Ocean,
with a total coastline of about 113 kilometers
Geophysical Environment
12. Geophysical Environment
• the towns of Maconacon,
Divilacan, and Palanan
are within the Northern
Sierra Madre Natural Park
(NSMNP)
• Dinapigue, the
southernmost coastal
town, is only partially
covered by NSMNP
• the Northern Sierra Madre
mountain range system is
among the most unique
and richest on a per area
basis among the park
systems in the Philippines
13. Geophysical Environment
• NSMNP covers 359,486 hectares,
80% of which consists of terrestrial
and 20% of coastal water areas
• NSMNP is characterized by
undistributed lowland dipterocarp
rainforest, limestone forest,
mangroves, beach forest and marine
eco-systems
• the Sierra Madre also boasts of
pristine fresh waster bodies such as
lakes, rivers, and streams
• vast potential for hydroelectric power
plants, potable water supply
systems, irrigation facilities and
tourism projects
14. Land Use
• predominantly forest land, with about 86% of
the total land area allocated for protection and
production forest
• Dinapigue has the largest forest cover with
98% of the town’s land area is classified as
forest
• Palanan has the largest agricultural land
among the four towns
• Divilacan holds vast tracts of mangrove
forests and classified 119 hectares of beach
or tourism area
• Maconacon and Palanan included bodies of
water and fishery in its existing land use
• 7,000 hectares of alienable land and
disposable land, mostly located in Maconacon
and Divilacan
15. Population
• total population of coastal towns as of
2007 census was 29,654, this is about
2% of the provincial population of the
same year
• massive out-migration in Maconacon
attributed to the closure of logging
companies in the municipality
• increase in population in Dinapigue
accounted to in-migration due to the
presence of logging and mining
operations in the area
• as of 2000, there were about 1,800
Agtas within the NSMNP boundaries in
mobile existence
16. Population
• the Agtas live in small groups of hunting
and gathering communities
• three (3) Certificates of Ancestral
Domain Claims (CADC) were granted
by the Department of Environment and
Natural Resources (DENR) to Agta
groups within Sierra Madre
• with the enactment of the Indigenous
People’s Rights Act (IPRA) in 1997, the
Agta can apply for legal ownership of
their indigenous territories
• the National Commission on Indigenous
People (NCIP) was tasked to convert
CADCs, a resurvey order was issued to
cover the domain to be included in the
application for Certification of Ancestral
Domain Title (CADT)
17. Education
• 33 educational institutions in the coastal
towns of Isabela: 13 primary schools, 15
elementary schools, five secondary
schools, one vocational school, and the
Isabela State University in Palanan
offering two collegiate courses
• at the secondary level, the student
classroom ratio in Dinapigue is
68:1,while Divilacan has 50:1 ratio,
which are both above the national
standard of 40:1
• some school buildings are either
deteriorating or are already dilapidated,
some students of different grade levels
share classrooms which makes the
setting not conducive for learning
18. Health
• health facilities in the coastal
municipalities are still wanting
• although a Rural Health Unit is
present in all four municipalities,
there are no facilities that can
address emergency cases
• patients have to be transported to a
nearest hospital which are hours
away
• access to hospital facilities time-
consuming, costly, or may not even
be possible due to the harsh
weather conditions
• renovation and upgrading of
facilities are needed
19. Local Economy and Public Finance
• the primary economic activities in the
coastal towns are agriculture and
fisheries
• the four municipalities have rich marine
resources that are still relatively
untapped due to lack of market and
post-harvest storage
• lack of transportation facilities and
expensive farm inputs
• post-harvest facilities are limited to
small-scale rice or corn mills and
dryers
• no fertilizers and pesticide dealers
20. Local Economy and Public Finance
• although the coastal area of the
Province is teeming with high-value fish
catch, the fishery sector cannot develop
due to lack of market, lack of post-
harvest facilities like cold storage area
and processing plant
• the marine resources are also
threatened by poaching of foreign
vessels due to lack of coastal and
fishery law enforcement
• the four coastal towns are part of the
One Town One Product (OTOP)
Program
• Maconacon is known for its coconut oil
production and by-products, Divilican
and Dinapigue for their fish production
and Palanan for its sabutan handicrafts
21. Local Economy and Public Finance
• to ensure food security and generate
income for the coastal municipalities,
there is a need to develop and
implement sustainable agricultural
and fishery programs
• the coastal towns depict an almost
closed economic system
• the buying and selling activities are
mostly constrained among the
coastal towns
• commerce and trade with nearby
provinces of Cagayan and Aurora are
limited
22. Local Economy and Public Finance
• farm inputs, construction materials,
and goods are sourced from Baler,
Dingalan, Aurora, Infanta and
Mauban, Quezon
• industries are limited in the coastal
towns except for small-scale
cottage industries like handicrafts,
furniture-making, weaving and
basket-making
• the geographic characteristics of
the coastal areas is typically cited
as the major barrier to outside
trading
• lack of regular power supply and
post-harvest facilities
23. Local Economy and Public Finance
• local economic growth had been
generally hampered by the lack of access
to external markets, money circulation is
likewise constrained
• sari-sari stores and a few commercial
shops are the only business enterprises
existing
• savings are kept in purses, attempts to
establish credit facilities and cooperatives
were not successful so far
• technical knowledge in managing small
financing facilities is lacking
• people do not have available windows
from where they can save and invest
their money
24. Local Economy and Public Finance
• with very robust farming and fishery
production, and high ecotourism potential,
the coastal towns have greatly relied on
support from the national coffers
• as to economic enterprises, Palanan and
Dinapigue have modest business
engagements such as public market
operations and public cemeteries
• Maconacon operates abandoned airstrip
and the causeway that serves as the
docking area for fishing vessels and
motorized bancas that transport cargo
and passengers to Sta. Ana, Northern
Cagayan
• management and operations of the
trading center needs to be greatly
improved
25. Development Goals for the
Coastal Towns
Future initiatives in the four coastal
towns are desired towards attaining
economic growth through
agriculture and tourism
development, and an improved
delivery of social services
undertaken with the least disturbance
to the natural environment.
27. Basic Project Information
Project Name: Ilagan – Divilacan Road Rehabilitation
and Improvement Project
Project Location: Barangay Sindon Bayabo in Ilagan to
Barangay Dicatian, Divilacan
Length: 82. 004 km
Type of Road: All-weather road with concrete
structures (reinforced concrete deck
girder bridges, reinforced concrete pipe
culverts, reinforced concrete box
culverts and slope protection)
Project Duration: 5 years (2012 – 2017)
Cost: P 2.28 B
Proponent: Provincial Government of Isabela
28. Project Rationale
• commitment to a comprehensive, dynamic and
sustainable development of Isabela
• Agriculture and Agri-business as its core
industries;
• Agro-forestry, Ecotourism and Fishery as
secondary industries
• potential of developing Renewable Energy,
particularly wind and hydro power
With this vision, the coastal municipalities will play
a vital role particularly in the fields of Agro-
forestry, Ecotourism, Fishery and Renewable
Energy. Hence, a need for the rehabilitation of the
Ilagan-Divilacan Road, as it will pave way for
these development opportunities.
29. Necessity of the Project
1. Because of the absence of access from inland
Isabela to coastal Isabela:
a) The residents of the coastal municipalities have
been deprived of affordable transportation, speedy
and effective delivery of services from National
Government Agencies and the Local Government
Unit especially in times of calamity; and
b) The residents of inland Isabela have been
deprived of the opportunities to visit the tourist
attractions in the coastal areas because of exorbitant
transport expenses.
30. Necessity of the Project
2. Extreme poverty of the upland dwellers will be
reduced with the aid of livelihood opportunities.
Hence, pressure in the forest will be reduced.
3. The capability of the Government in protection,
conservation and reforestation will be greatly
enhanced. Law-enforcement agencies can move
speedily from inland areas to upland and coastal
areas; mobilization on reforestation projects will be
enhanced and will be more effective; and slope
protection in landslide prone areas will be
established.
31. Beneficiaries of the Project
1. The direct beneficiaries of the project are
the residents of the coastal areas, upland
dwellers (Agtas and other communities)
within the vicinity of the project.
2. The indirect beneficiaries are the Isabeleños
as a whole and other stakeholders and
investors.
3. Government Agencies
4. In strategic sense, the NSMNP.
