The State of the Philippine Environment:

The Philippines is one of the 17 biological wealthiest nations

THE PHILIPPINES = Megadiversity Country and Biodiversity Hotspot

“The Philippines is one of the few nations that is, in its entirety,

both a biodiversity hotspot and a megadiversity country, placing it among the top priority hotspots

for global conservation.” Conservation International

IMPORTANCE OF BIODIVERSITY:Ecosystem Services

•GAS REGULATION, e.g., CO 2/O2

balance, O3 for UVB protection

•CLIMATE REGULATION, e.g., greenhouse gas regulation,

•DISTURBANCE REGULATION, e.g., storm protection, flood control, drought recovery

•EROSION CONTROL and SEDIMENT RETENTION, e.g., prevention of loss of soil by wind, runoff, or other removal processes

IMPORTANCE OF BIODIVERSITY:Ecosystem Services

•NUTRIENT CYCLING, e. g.,

•DISTURBANCE REGULATION, e.g., storm protection, flood control, drought recovery

•WATER REGULATION, e.g., production of water for industrial and agricultural processes

•WATER SUPPLY, e.g., provisioning of water by watersheds, reservoirs and aquifers

• critically endangered .• Total forested area in the country as of 2003 = 7.2 M hectares or 24% of total land area of 30 M hectares. The Philippines needs forest cover of 54% of total land areas in order for it to be ecologically sound and able to sustain its ecosystems and their services.

MANGROVES50+ species worldwide

35-40 species found in the Philippines,Including 20-30 species of shrubs & vines

Remaining primary mangrove forests are found in Pagbilao Bay (Quezon Province), Ulugan Bay (Palawan) and Bais Bay (Negros Oriental).

A hectare of mangroves

produces 12.5 m3 of firewood and 900 kg. of finfish yearly.

(Ronnback 1999)

Are mangroves

important? •Act as natural buffer

of coastal areas against storms, wave

and wind erosion, and flooding.

•Serve as sinks for organic and inorganic

materials, including pollutants.

•Are nursing grounds of many fish and shrimp species.

Seagrass Beds• Provide food and shelter for fish and other marine organisms.

• Stabilize sediments and prevents erosion along coastlines

• Take up dissolved nutrients and trap sediments in the water resulting in high water clarity UNEP AC Alcala

CORAL CORAL REEFS:REEFS: rainforests of the sea

Occupy less than 1% of EARTH’S SURFACE

yet support more than 25% of world’s

total fish catch

•Contribute at least US$400 billion a year to the world economy

•Coral reef fisheries contribute almost

US$1 billion annually to the Philippine

economy and provide livelihood to more

than 1 million small-scale fishers

1 sq. km. of healthy coral

reef can provide the protein

needs of more than 300 people

a year

The Philippines is the “center of the center” of marine shore fish diversity.

Along with Malaysia and Indonesia, it is part of the CORAL TRIANGLE, which has the highest concentration of marine life on the entire planet!

430 species in 70 genera = 80% of world’s coral species

12 species endemic to the Philippines and Indonesia

Almost 70% of the mangroves in the Philippines have been destroyed since the 1920s

Estimated mangrove areas:

1918 – 500,000 has.

1970 – 288,035 has.

1990s – 140,000 has.

2000 – 109,700 has

The single most significant cause of mangrove destruction = habitat loss due to intensive and

uncontrolled aquaculture activities.

TRENDS: Mangroves

TRENDS: Coral Reefs Philippine coral reef surface

approx. 27,000-33,000 sq. km.

Reefs in excellent condition: 1991 = 5.1%

2000 = 4.3%

2004 = 0.24%

Rate of coral destruction = 120 ha/day or 36,000 ha/yr from blast fishing and muro-ami

The Philippines loses $420 million annually in potential revenues from mismanagement of fisheries resources.
