Sorsogon City Climate
Vulnerability and Adaptation (V&A)
Assessment!
“ to validate City exposure to
climate change impact and define
its sensitivities and adaptive
capacities”
V&A Assessment Process
 Formation
of Technical Working Group
 Definition and agreement on objective and
framework
 Localizing of climate change
scenario/exposure
 Assessment of sensitivities (hotspots!)
 Ground truthing of findings thru FGDs with
communities
Sorsogon City CC Exposure/Scenario

Risk is Very High on
combined risks to
typhoons, drought
caused by El Nino,
projected rainfall
change and
projected
temperature increase
according to the
DENR/Manila
Observatory data
Sorsogon City CC Exposure/Scenario
1. Tropical Cyclones

The city is situated in
the country’s
geographical zone 6
where at least 3
cyclones every two
years pass
(PINCCC)

2006 super typhoons
Milenyo and Reming
devastated the city
Sorsogon City CC Exposure/Scenario
2. Temperature Change :

2-3 degrees centigrade
increase in temperature
3. Increased Precipitation
 50% increase in annual
rainfall
4. Sea Level Rise
 Increasing trend in annual
mean sea level occurred
since 1970

Findings, Implications and Challenges
Governance and Development Programming

The land use plan must be revisited considering the projected
risks were found in the built environment (hotspots).

There are also hotspots in the Agricultural (Osiao and Sto.
Nino) and Mangrove areas (Gimaloto). This would have
implications on the existing city agri and environment
programs.

The city has not considered yet the risks areas and climate
change impacts into its physical development planning.

Data and information management needs to be developed
(GIS, Knowledge Management)
Findings, Implications and Challenges
Governance and Disaster Risk Management:
-
-
Need to strengthen CDCC and BDCC
including coordination systems with the
Provincial and Regional levels
Integration of climate change and DRM in the
development planning of the City
Enhancing preparedness and mitigation
Findings, Implications and Challenges
Governance and Institutional Coordination:
-
Given the complexities of City CC sensitivity, the
different tiers of local government and other
stakeholders need to improve coordination and
collaboration mechanisms
-
Support of private sector (from within and outside
the city) in Climate Risk Management is still very
limited thus needs strengthening
Findings, Implications and Challenges
Settlements/Built-Up Area:
 Most of the Hotspots are host to major commercial and residential
areas
 total population in the hotspots is 41,257 where 35,621 is at the
urban and urbanizing barangays
 informal settlers are located in the shorelines of the hotspots

22,000+ women at risk

Poverty Incidence: 43%
Given increased precipitation and flooding in some
areas, urban slums are at high risk to climate related
diseases and illnesses.
Increased salinity of source of drinking in some areas
Limited knowledge on climate change was emphasized
during FGDs with communities
A large number of housing structures in the hotspots are
made light materials while the protective community
structure (sea wall) is aging, damaged, and needs repair
Community FGD (Sirangan & Poblacion)
Community FGD (Talisay & Cambulaga)
Findings, Implications and Challenges

Agriculture: 2,482 has. of rice
paddies tilled by 3,313 farmers
and 9,930 has. of coconut
areas managed by 7,272
farmers are vulnerable to
tropical cyclones

Most vulnerable areas are
located in the 9 hot-spots (211
farmers tilling 205.75 ha.)

Agri sector needs
preparedness and adaptation
measures based on its
vulnerabilities and seasonalities
and enhancing its economic
base opportunities for the city
Rice Variety/Breed
Resiliency Type
IR 64
PSB Rc18
PSB Rc 76H
IR 42
Adaptable to excessive rain water
and flooding. Also classified as tall
varieties.
PSB Rc16
PSB Rc24
PSB Rc70
UPL Ri7
UPL Ri5
Less water/drought, dry seeded
varieties and also suitable for upland
and rainfed type of farming.
PSB Rc8
PSb Rc6
Short stand varieties, more resilient
to strong winds
Findings, Implications and Challenges

Vulnerable fishing
communities are the ones
using conventional fishing
and the green mussel
producers

There are 1,291 fisherfolks
and 211 fish vendors in the
9 hot-spot areas

Need to develop
complementing and
adaptive livelihood
activities to reduce their
vulnerability
