• Philippines and the issue of climate change

• Philippine fisheries and marine ecosystem profiles

• Data source: National Stock Assessment Program

• Pelagic species composition and seasonality

• Summary and conclusion Climate change policy in the Philippines

Philippine Republic Act 9729: • Climate Change Commission “Climate Change Act of 2009”

National Framework Strategy CLIMATE CHANGE on Climate Change • Increasing temperature • Changing rainfall pattern • level rise • Extreme climate events

VISION IMPACTS AND CLIMATE PROCESS DRIVERS A climate resilient Philippines with healthy, VULNERABILITY • Energy safe, prosperous and self‐reliant • Ecosystems (River basin, coastal • and marine, biodiversity) Framework and strategies in • Transport • Land Use Change & Forestry communities, and thriving and productive • Food security • • Agriculture ecosystems Water resources • Human health • Waste • Infrastructure SUSTAINABLE • Energy DEVELOPMENT • Human society Goal: To build the adaptive SOCIETY ENVIRONMENT place capacity of communities and increase the resilience of natural ecosystems to climate change and optimize mitigation opportunities towards ECONOMY sustainable development

MITIGATION ADAPTATION • Energy efficiency and conservation • Enhance Vulnerability and Adaptation Assessment • Sustainable infrastructure • Integrated Ecosystem –based Management • Renewable energy • Climate Responsive Agriculture • Adaptation is priority • Environmentally sustainable transport • Water Governance and Management • National REDD+ Strategy • Climate Responsive Health Sector • Waste Management • Disaster Risk Reduction and Management

• Consistently one of the top 10 countries predicted to be adversely affected by CC

• About 70% lives in coastal areas

• About 70% of protein requirement comes from fish

• Low levels of socio-economic capacities in many of these coastal communities Some Philippine Climate Change-Related Data

Sardinella lemuru One stock species stocks, Different Interpreting National Stock Assessment Program (NSAP) (since 1996)

• To create a standardized, specific and time‐series information on marine capture fisheries around the country for management purposes

• To develop and institutionalize the capability of the 16 regional offices in fishery stock assessment

• Included in Philippine GAA National Stock Assessment Program (NSAP) (Landed Catch and Effort Monitoring by FAO)

Orientation and • Catch estimates Training • Gear inventories

• Catch per unit effort (CPUE) Implementation • Species composition and seasonality

• Length frequencies, Population parameters Reporting • Maximum Sustainable Yield (MSY), Potential Yield (PY), Exploitation Ratios etc. National Stock Assessment Program (NSAP) (Database) Things to remember

• Multi‐species, multi‐gear fishery

• Different biogeographic regions and stocks

• Very limited specific historical data on fisheries

• Limited historical meteorological data

• Major ENSO events in 1997‐1998 and 2009‐2010 OceanicOceanic TunasTunas (Family(Family Scombridae)Scombridae)

• Diversity and variability abounds in the Philippines

• Different areas have different dominant species composition

• Different areas show different species seasonality patterns

• Suggest a play of fishing or climate or both fishing and climate, add analysis and data
