3. Coastal and Marine resourCes under Pressure
The. main. pressures. affecting. Philippine.coastal. and. marine. areas. are. agriculture. and.forestry. activities,. urban. and. industrial.development,. tourism.development,.oil.and.gas.exploration,. minerals. and. mining,. population.growth. and. fish. consumption,. and. climate.change.. This. chapter. explores. each. of. these.issues,. including. their. social,. political,. and.economic.context..
agriculture and forestry.. The. early. onset. of.industrial. logging. in. the. Philippines—.combined. with. a. lack. of. proper. forest.management—has. resulted. in. the. loss. of.nearly. 80. percent. of. the. Philippines’. original.forest. cover.. In. 1990,. 10.6. million. hectares.were. classified. as. forest;. by. 2005,. the. total.had. declined. to. 7.2. million. hectares,. or.a. loss. of. 3.4. million. hectares. (FAO. 2005).. Over.the. past. 15. years,. the. average. annual. forest.loss. was. equivalent. to. almost. 227,000. hectares.per. year.. Forest. loss. combined. with. poor. land.management. and. unsustainable. farming.practices. lead. to. soil. erosion. and. increased.flooding,. resulting. in. higher. costs. of.infrastructure. maintenance,. as. well. as. higher.risks. to. lives,. property,. and. productivity..Soil. erosion. reduces. light,. smothers. marine.organisms,. and. prevents. the. recruitment. and.recovery.of.areas.that.have.been.silted.over..
Agricultural. runoff. is. a. growing. source. of.pollution. in. bays. and. near-shore. waters.. The.surface.runoff.consists.of.residues.from.livestock.and. poultry,. fertilizer. and. pesticides,. and.decaying.plant.matter.
urban and industrial development.. Almost. all.near-shore.ecosystems.within.or.near.urbanized.areas. in. the. Philippines. are. threatened. by.organic. pollution—that. is,. nutrients. from.industrial,.commercial,.and.domestic.wastewater.carrying. organic. wastes. and. fertilizer. residue..nutrients.enhance.the.growth.of.algae.(including.those.that.cause.red.tides).and.bacteria,.which.in.
turn.reduces. light.and.oxygen,.resulting. in. fish.kills..Red.tide.has.become.a.yearly.occurrence.in.some.coastal.areas.of.the.country.
Sewerage. infrastructure. is. inadequate. or.nonexistent.. Centralized. sewerage. collection.and. treatment. facilities. cover. only. parts. of.Metro. Manila,. while. Metro. Cebu. and. Metro.Davao have no centralized sewerage systems.at. all.. Many. areas. have. septic. tanks. that. often.do.not.have.seepage.or.leaching.devices.and.are.not. maintained,. thus. making. them. often.inefficient. and. ineffective. in. reducing. nutrient.pollution.. The. expansion. of. domestic. water.supply. systems. in. major. coastal. cities. is. also.increasing.the.volume.of.wastewater.
Each. year,. nearly. 2.2. million. tons. of. organic.pollution.are.produced.by.domestic.(48.percent),.agricultural. (37. percent),. and. industrial. (15.percent). sectors. (World. Bank. 2003).. The.industrial. sector. accounts. for. most,. if. not. all,.of. the. toxic. and. hazardous. waste. discharged.into. water. bodies,. a. finding. confirmed. by.studies. carried. out. by. the. Environmental. and.natural.Resources.Accounting.Project.(EnRAP)..

The.main.substances.are.mercury.(Hg),.chromium.(Cr),. sulfides,. phenols,. phosphorus. pentoxide,.and.fluoride..
Tourism development.. Coastal. tourism. has.contributed. to. the. pollution. of. coastal. areas..Pollution. from. this. sector. is. usually. lumped.under. the. household. sector,. as. the. generated.waste.is.domestic.
Waste. from. tourism. activities. also. primarily.affects. the. business. itself.. A. concrete. example.of. this. is. Boracay. where,. for. a. time,. the.number.of. tourists.dwindled.as.a.result.of.high.coliform. counts. from. its. beaches.. Most. coastal.resorts. are. still. poorly. planned. in. terms. of.environmental. protection.. The. larger. resorts.have.only.recently.begun.to.implement.stringent.environmental. practices. on. their. properties.(Hütcche.et.al..2002)..In.many.cases,.the.building.

the. major. natural. gas. deposits. of. the. country,.estimated. to.contain.2.5. to.3.2. trillion.cubic. feet.of. recoverable. gas. (Balce. and. Pablico. 1997)..This. discovery. of. offshore. commercial. natural.gas. resources. provided. the. impetus. for. the.development.of.the.Philippine.gas.industry.
Other. offshore. gas. deposits. have. been.discovered.in.the.Reed.Bank.and.South.Palawan..DangerousGroundsandSpratlyIslands,whichare. claimed. in. part. by. other. nations. as. well. as.the.Philippines,.share.a.common.geology.as.the.Reed.Band.and.north.Palawan,.suggesting.that.potentially. large. petroleum. reserves. may. also.be.found.in.these.areas.
Another. major. site. for. oil. and. gas. exploration.activities.in.the.last.three.decades.is.the.Western.Sulu.basin..This. is.a.“frontier”. (underexplored).region. with. comparatively. low. drilling. density.(11.wells.within.Philippine.territorial.waters;.10.wells.offshore.Sabah.since.1970)..
The. main. environmental. impacts. of. oil. and.gas. include.operational.wastes,.such.as.drilling.fluids. and. drilling. muds;. drainage;. leaks. from.offshore.pipelines;.and.oil.spills..noise.and.other.kinds. of. disturbance. from. offshore. oil. and. gas.operations.may.also.affect.marine.mammals.
Minerals and mining.. Sand. and. gravel. mining.is. a. common. activity. in. coastal. areas.. In. many.cases,. it. leads. to. increased. coastal. erosion..Land-based. mining. can. cause. significant.environmental. impacts,. many. of. which. are.harmful.to.human.health..Mine.tailings.disposal.has. often. been. indiscriminate.. Some. tailings.have.found.their.way.into.coastal.waters..Improper.impoundment. of. wastes. and. tailings. may. lead.to. disastrous. accidents,. such. as. the. case. of.massive. toxic. spills. from. Marcopper. in.Marinduque.. It. was. estimated. that. the. amount.of. lost. income. due. to. the. accident,. and. from.coastal. fishing. alone,. was. PhP. 9.2. million. in.1996.(Box.3.1).(Bennagen.1998).
Box 3.1 Decades of Mining Destroyedan Island Paradise.
Marcopper began mining copper on Marinduque Island in the Philippines four decades ago. It dumped millions of tons of toxic mining waste into Marinduque’s coastal waters and polluted its rivers. As a result, local inhabitants have lost their health, livelihoods and some even their lives. After a major accident in 1996, the Philippine Government closed down the mine.
Recent field investigations and a scientific survey funded by Oxfam Australia’s Mining Ombudsman revealed that—almost a decade after the mine has been closed—a main river is still polluted from the continuous runoff from the mine and old tailings left behind. The high acid and metal levels in the river are a hazard to humans and aquatic life. Local health is strongly affected by skin diseases, which local people blame on toxic mine waste. Fishermen have lost limbs, which they believe is the result of arsenic contamination. Stomach complaints, dementia, and cancer are also common. Local inhabitants have received little or no rehabilitation of their environment, nor any payment of compensation.

While. the. exploitation. of. land-based. metallic.and. nonmetallic. mineral. deposits. is. a. major.contributor. to. the. country’s. economy,. the.potential.of.mining.marine.mineral.resources. in.Philippine. offshore. areas. has. received. little.attention.. As. technological. advances. in. ocean.mining. develop,. ocean. floor. minerals. will.probably.be.explored.as.possible.alternative.sites.for. future. mineral. exploitation.. Polymetallic.sulfides. and. manganese. deposits. are. among.the. potential. mineral. resources. from. the. ocean.floor.. Based. on. knowledge. of. tectonic.environments. favorable. to. the. formation,.accumulation,. and. preservation. of. polymetallic.sulfides,. the. marginal. basins. around. the.Philippines. are. promising. exploration. grounds.(Yumul 1993). Sulfide deposits contain copper,lead,. zinc,. silver,. gold,. and. possibly. other.alloys.. The. Scarborough. Seamount. Chain.Plateau.offshore.of.northeastern.Luzon,.and.the.Cagayan. de. Sulu. Ridge. in. the. Sulu. Basin,. are.likely. sites. for. these. sulfide. deposits.. For.manganese. nodules,. only. the. West. Philippine.Basin.appears.to.be.a.good.target.site..
The. potential. environmental. impacts. of.marine. mining. include. pollution. from. waste.and. mine. tailings,. increased. water. turbidity.(cloudiness.in.water),.and.debris.and.sediments.that. may. have. an. effect. on. local. marine. life..Removal. of. sand. from. the. sea. floor. can. cause.severe.erosion.and. loss.of.marine.habitat;. such.alterations. may. also. cause. a. change. in. wave.regime. that. could. affect. coastal. erosion.. noise.and.other.kinds.of.disturbances.from.operations.may.also.affect.marine.mammals.
Population growth and fish consumption.. Fishery.exports. were. about. 173,887. MT. in. 1997. and.196,087.MT.in.2004,.valued.at.PhP.16.billion.($327.million). and. PhP. 27. billion. ($543. million).respectively..Over.a.period.of.seven.years,.volume.grew.by.an.average.of.3.percent,.while.the.value.of. fish.exports.grew.on.average.9.percent..Over.
the.same.period,.the.volume.of.imports.decreased.by.an.average.of.5.percent.(Figures.3.2.and.3.3).
During the past two decades, the annual.population. increase. in. the.Philippines.has.been.about. 2.2. percent. per. year.. Fish. consumption.in. the. Philippines. is. about. 28.5. kilograms.per. capita. per. year. (Barut. et. al.. 2004).. The.increased.demand.for.fish.by.a.rapidly.growing.population,. and. increasing. exports. due. to.increasing. fish. prices,. have. substantially.increased. the. pressure. on. marine. fishery.

resources. over. the. past. two. decades.. Table. 3.2.illustrates. a. projection,. which. assumes. that.average. fish. consumption. continues. to. be. 28.5.kilograms.per.capita.per.year.
Without. any. change. in. fish. consumption. and.no. active. human. population. management.program,. domestic. demand. for. fish. will. reach.3.2. billion. kilograms. (3.2. million. MT). by. 2020,.given. the. projected. population. growth. rate. of.the.country..
If. increased. demand. is. met. solely. by. marine.capture. fisheries,. such. increased. pressure. on.the. fisheries. sector. could. lead. to. an. eventual.collapse.of.fisheries.and.the.fishing.industry.
As. mentioned. in. Chapter. 2,. declining. CPUE.is. an. indication. of. overexploitation.. When. we.compare. the. Philippines. and. five. other.countries. in. the. region. (Figure. 3.4. on. previous.page),. the. result. seems. to. confirm. this. trend,.even. though. comparing. fisheries. indicators.among. countries. is. problematic. because. of.
the. inherent. differences. in. resource. and.technology.characteristics.

more. heavily. exploited. than. elsewhere.. An.analysis.of.mullet,.grouper,.and.bream.landings.(the.part.of.the.fish.catch.that.is.brought.ashore).is. particularly. worrying.. Figure. 3.5. illustrates.the. change. in. landings. of. these. fish,. which.represent. important. target. species.over. the. last.three.decades.
Because. marine. capture. fisheries. are. over-exploited,. the. growing. demand. for. fish.will. eventually. have. to. be. met. by. an. increase.in. aquaculture. production.. Costs. to. the.environment,. however,. will. have. to. be. taken.into.account..Environmentally.friendly.aquaculture.is.possible.with.adequate.planning,. investment,.and. consideration. of. potential. impacts. and.mitigation.on.vulnerable.coastal.mangrove.and.reef.ecosystems..
Climate change.. The. Intergovernmental. Panel.on. Climate. Change. (IPCC). has. concluded. that.(a).atmospheric.greenhouse.gases.have.increased;.(b). the.average.surface.temperature.of. the.earth.has. increased. since. 1861. by. about. 0.6. degrees.Celsius;. (c). global. average. sea. level. have. risen.between.0.1.and.0.2.meters;.and.(d). rainfall.has.increased. by. 0.2. to. 0.3. percent. per. decade. over.the.tropical.land.areas..
Potential. impacts. of. climate. change. on. coastal.areas.are.summarized.in.Box.3.2.
The. potential. influence. of. climate. change. and.sea-level. rise. on. Philippine. coastal. areas. and.resources. is. only. now. beginning. to. be. studied..nevertheless,. based. on. measurements. over. the.last. 100. years. and. various. projected. global.scenarios,. fairly. good. inferences. can. be. made.about. the. possible. impact. of. such. changes. on.Philippine.coasts.over.the.next.50.to.100.years.
Temperatures.seem.to.be.rising.slightly.all.over.the. Philippines. and. in. the. surrounding. coastal.waters..The.1990s.were.the.warmest.decade.in.the.last.century,.and.1998.was.the.warmest.year.on.record. in. the. Philippines.. That. year. coincided.with.the.most.extensive.coral.bleaching.episode.ever.observed.on.Philippine.coral.reefs;.about.15.to.20.percent.of.the.country’s. living.corals.were.killed..Average.air.temperature.in.the.Philippines.has.risen.by.about.0.5.degrees.Celsius.since.1980..This. warming. has. been. accompanied. by. a. 6.percent.average.decline.in.annual.rainfall.over.the.last.century..This.drying.occurs.primarily.during.theDecembertoFebruaryseason(WWF1999).

Box 3.2 Potential Impacts of Climate Change and Sea-Level Rise on Coastal Systems.
Climate change and a rise in sea-level can have a number of biophysical and related socio-economic impacts on the Philippines. Potential biophysical impacts: • Increased coastal erosion. • Inhibition of primary production processes. • More extensive coastal inundation. • Higher storm-surge flooding. • Landward intrusion of seawater in estuaries
and aquifers. • Changes in surface water quality and
groundwater characteristics. • Changes in the distribution of pathogenic
microorganisms.• Higher sea-surface temperature.
Potential socio-economic impacts:• Increased loss of property and coastal habitats.• Increased flood risk and potential loss of life.• Damage to coastal protection works and other
infrastructure.• Increased disease risk.• Loss of renewable and subsistence resources.• Loss of tourism, recreation, and transportation
functions.• Impacts on agriculture and aquaculture through
decline in soil and water quality.

1. The.IPCC.Third.Assessment.Report.states:.“sea-level.rise.is. regarded.as.one.of. the.more.certain.outcomes.of.global.warming.and.already.is.taking.place..Over.the.past.100.years,.global.sea. level.has.risen.by.an.average.of.1-2.millimeters.per.year,.and.scientists.anticipate.that.this.rate.will.accelerate.during.the.next.few.decades.and.into.the.22nd.century.”
A. relative. rise. in. sea-level,. regardless. of. its.cause,.has.a. real. effect.on. the. coastal. area.as. it.causes. inundation. of. low-lying. areas.. Several.studies. have. shown. the. vulnerability. of. the.Philippine.coasts.to.a.relative.change.in.sea.level.and. erosion. forces. on. beaches.. Most. studies.have. focused. on. the. Manila.

The. vulnerability. of. other. coastal. areas. of. the.Philippines.will.depend.on.the.actual.rise.in.sea.level.as.a.result.of.global.changes.in.temperature,.glacial. ice.melting,.and.other. factors,. including.shoreline.topography.and.elevation..Most.major.Philippinecities—suchasDapitan, inLingayenGulf,partsofDavaoCity,andreclaimedportionsof. Cebu. City. among. others—are. situated. on.relatively.low-lying.areas.
Projected.possible. increases. in. storm.frequency.and. strength. due. to. global. warming. will. also.affect. coastal.areas.with. flooding. from.extreme.high. tides,. mud. slides,. and. increased. erosion.rates..Although.data.on.changes.in.storm.patterns.is.still.preliminary,.even.assuming.the.status.quo.it.is.clear.that.higher.tides.combined.with.regular.typhoon-strength. storms. will. yearly. cause.significant. damage. along. the. coasts. that. are.exposed.to.such.storms..Such.damage.can.only.be.mitigated. with. preventive. planning. along.shoreline.areas.and.the.implementation.of.building.and.development.setbacks.along.beaches.and.all.low-lying.shorelines.
Climate.change.would.also.strongly.affect.coral.reefs.through.a.changing.marine.biochemistry..As.the.ocean.warms,.its.capacity.to.dissolve.carbon.dioxide.could.decrease.by.14.to.30.percent,.leading.to. a. decrease. in. biological. carbonate. formation.that.is.essential.for.reef.building.(Hardy.2003).
In. summary,. climate. change. and. sea-level. rise.could.have.major. impacts.on.Philippine.marine.and.coastal.resources..
To. prevent. or. mitigate. these. various. changes.and. impacts,. climate. change. responses. and.measures—such. as. the. implementation. of.setback. regulations,. appropriate. land. planning.in. coastal. areas,. and. the. strengthening. of. coral.reef. management. to. enhance. the. natural.resilience. of. coral. reef. communities—need. to.be. part. of. ICRM. schemes. and. strategies.. In.addition,. more. studies. on. mitigation. and.adaptation. to. climate. change. in. coastal. areas.are.needed.
