Magsino-Lubis, Sta. Teresita, Batangas
TAAL,
the deepest lake in the Philippines and the third largest with
an area of 23 sq km, is being threatened by large-scale illegal fishing,
inappropriate development for tourism and settlements on the Tagaytay ridge,
and solid waste and agricultural runoff.
A study of the Tanggol
Kalikasan (TK), a public interest environmental law office, shows that the
number of floating cages of cultured tilapia and bangus (milkfish) have
increased, threatening endemic species in the lake and causing
pollution.
Decayed fish feeds
are depleting the lake's supply of dissolved oxygen, it says, while
discarded feed bags litter the waters.
The study warned
that tapping a billion cubic meters of lake water for
irrigation and urban use could weaken the ecosystem, which supports a variety
of marine life, and restrict aquatic migration.
Realizing urgent
action to counter the threats, mayors of the 10 towns and three cities
surrounding Taalsigned
a covenant to conserve and protect one of the world's most active volcanoes on
Jan. 26 at the Sta. Teresita municipal covered court.
The move, initiated
by the TK, aimed to ensure pollution control, regulated operations of fish
cages, and the apprehension of illegal fishers in the lake.
Hopefully, the measures will result in the return of endemic fishes that have
been on the country's list of vanishing species for decades.
Lawyer Asis Perez,
TK area director, said the covenant should have been signed several years ago,
but he was positive that the effort was not yet too late.
Signatories
Mayor Vilma
Santos-Recto of Lipa City was the first to sign the covenant on Jan. 21. Other
city mayors who signed it are Abraham Tolentino of Tagaytay and Alfredo Corona
of Tanauan.
The rest of the
mayor-signatories were Glorioso Martinez of Agoncillo, David Pamplona of
Balete, Danilo Sombrano of Mataas na Kahoy, Adorlito Ginete of Sta. Teresita,
Guillermo Reyes of Alitagtag, Enrique Comia of Cuenca, Cristeta Reyes of
Malvar, Napoleon Arceo of San Nicolas, and Florencio Manimtim Jr. of Talisay.
Batangas Gov.
Armando Sanchez challenged the local chief executives to put their covenant
into action.
"When you
signed that covenant to conserve Taal Volcano, you have
already committed yourself," Sanchez told the mayors in a speech.
"In Batangas,
your word means action because your governor wants things done as they should
be. Gone are the days of broken promises," he added.
Environment
Secretary Michael Defensor was represented by his regional director, Ernesto
Adobo.
Taal Lake
Taal Lake is
located within a complex volcanic area. A small volcanic island lies in the
middle of thelake, which has been the site of 33 documented volcanic
eruptions since 1572.
The island is a main
viewing attraction of tourists from the Tagaytay ridge and Mt. Maculot.
Taal Volcano
itself has a lake of its own inside the crater.
A 1927 fish
inventory of Taal Lake identified 76 migratory
species and many endemic species. But a 1995 study showed only 15 species of
migratory fish and only four endemic fish species remaining in thelake.
In 2002, the volume
of tawilis, a freshwater herring found only in Taal Lake and
which the fishermen used to catch by the tons, had been reduced to less than a
thousand.
The sensitive fish
was the first to die due to frequent temperature changes and water pollution
brought by wasted feeds in the big fish cages.
Freshwater sharks
used to thrive in the lake before they were totally driven
away as a result of overfishing in the 1930s.
Rosa Macas, regional
director of the Bureau of Fisheries and Aquatic Resources, said 30 percent of
the fish feeds settled at the bottom of the fish cages. When the feeds rot,
they deplete the oxygen level of the waters, threatening fish species.
Aside from the
tawilis, the endemic fishes that are endangered are the duhol or sea snake,
maliputo (freshwater mackerel), igat (freshwater eel), the three-millimeter
pygmy goby (Pandaca pigmaea), apta and yapya (freshwater prawns), and the paros
and suso, two types of mollusks.
Protected landscape
The government
declared Taal Lake a national park on July 22,
1967, through Presidential Proclamation 235.
In 1996, it was
declared a protected landscape under the National Integrated Protected Areas
Systems Act.
Three lake-wide
institutions authorized by different laws share the governance of the lake.
These are the Protected Area Management Board (PAMB) under the protected areas
law, the Integrated Fisheries and Aquatic Resources Board under the Fisheries
Code, and the Lakewide Development Council.
But the only entity
that has undergone a management planning was the Presidential Commission on
Tagaytay-Taal in 1993, which was abolished in 2000 allegedly
because the PAMB had already been created.
Because of the
number of management bodies exercising overlapping jurisdictions over the lake,
they are unlikely to make any dent on the major issues affecting it.
The Kilusan ng Maliliit na Mangingisda sa Lawa ng Taal,
a lake-wide organization, has also been helping to conserve the lake during
the last 18 years.
