SESAM profs assist in formulating the management plan of a young lake in Oriental Mindoro

Caluangan LakeCaluangan Lake in Calapan City, Oriental Mindoro is one of the youngest lakes in the country, formed after an earthquake in the province 24 years ago.

A team of professors from SESAM composed of Dr. Rafael D. Guerero, Dr. Antonio J. Alcantara and Dr. Rico C. Ancog has conducted an ecological survey of the Calapan (Caluangan) Lake in Calapan City, Oriental Mindoro, last 25-26 March 2018. Being the lake’s overall manager, the City Government of Calapan under the leadership of Mayor Arnan Panaligan, saw the need to proactively formulate a management plan that would ensure sustainability of the lake particularly in outlining of the rules and regulations on its planned mariculture zone and other uses. Assisted by Dr. Marius Panahon, a SESAM alumnus and the current Technical Officer of the Fisheries Development Office of Calapan City, the team explored the Baruyan River and the lake, and conducted focus group discussions with fisherfolks and city officials.

IMG 7101IMG 7109SESAM Professors led by Dr. Rico C. Ancog, Dr. Rafael D. Guerero and Dr. Antonio J, Alcantara joined the LGU officials of Calapan City, Oriental Mindoro, as well as the Philippine National Police in surveying the Caluangan Lake.

Lake Caluangan is one of the youngest body of water in the country having been formed through an earthquake 24 years ago. The lake provides multiple uses particularly for fishing, brackishwater fishponds, and tourism activities. A number of subsistence fishermen from 6 fringing coastal barangays using non-motorized bancas and fish corrals (baklad) of various sizes. A sizable area of mangrove “Green Belt” on the northwestern bank of Baruyan River has been maintained by the Department of Environment and Natural Resources (DENR) though scouring of some portions of the river bank could also be observed.  Overall, the water of the lake is greenish with transparency of about 30 cm and depth averaging at 6 meters with its bottom being most clayey. An existing floating fishcages for bangus (Chanos chanos) and samaral (Siganus guttatus) are being managed by HAYUMA, a federation of small fisherfolks from 29 barangays fringing the lake.

The exercise of formulating the management plan for Caluangan (Calapan) Lake provides an opportunity for mutual interactions among SESAM-UPLB as an academic institution and public service provider, the City Government of Calapan as the resource manager, and the local communities as resource users---with the end goal of conserving Caluangan (Calapan) Lake as a critical resource. 

Jobus dye study bagged Best Poster in 2018 UPREPS Conference

Suy posterBest poster. Dr. Yusof A. Sucol co-authored the best poster with Dr. Decibel F. Eslava, Dean of SESAM, Dr. Carmelita M. Rebancos, Professor, SESAM and Prof. Mildred A. Padilla of the College of Veterinary Medicine-UPLB.

The poster paper entitled “The fish that we eat and the jobus dye: what we don’t know and what can be done” by Dr. Yusof A. Sucol, University Researcher II of the School of Environmental Science and Management (SESAM), won the Best Poster Award for the Social Science Category on the recent UP Society of Research, Extension and Professional Staff, Inc. (UPREPS) 5th Annual Scientific Conference and 9th General Assembly at Shercon Resort and Ecology Park, San Sebastian, Mataas na Kahoy, Batangas last March 21-23, 2018.

With the theme “The Role of REPS in Transforming UP into a World-Class Research Through Science and Innovation”, this year’s conference netted more than 100 REPS from the different colleges and units of UPLB. UPREPS is a SEC-registered organization established in 1986.

The study of Dr. Sucol was based on his dissertation funded by the Department of Science and Technology-Philippine Council for Health Research and Development (DOST-PCHRD) under his PhD in Environmental Science. His poster presented the evidences of deceptive fish vending and provided an insightful discussion on the potential toxicology of jobus to public health and the environment.

Dr. Sucol said fishes commonly treated with jobus are the ones we usually buy, cook and serve on our meals. These include bangus, galunggong, matang-baka, tulingan, tamban, alumahan and dalagang bukid. He added that jobus contains 95% coal tar and 2% sulfanilic acid, and his study suggests that coal tar-derived dye most likely contains polycyclic aromatic hydrocarbons (PAHs). “PAHs may cause mutagenicity, carcinogenicity and behaviorial abnobalities to humans”, said Dr. Sucol. In the environment, PAHs can accumulate in soils, plants, fishes and aquatic sediments, which may cause pollution in rivers and contaminate sources of water, he added.

Other SESAM REPS who presented their papers and posters during the conference were Dr. Loucel E. Cui, University Researcher II, who presented her study entitled “Training Needs Assessment of Farmers in the Philippines”; Cherry S. Padilla, University Research Associate II, presented a paper on “Harmonizing National Environment Laws and Policies with Local Ordinances: the Environment Code”; and Mr. Thaddeus P. Lawas, University Extension Specialist II, who presented a poster paper by entitled “Governance of a Municipality During Disasters: the Case of Sta. Teresita, Cagayan Province”.

In the closing ceremonies, UPLB Chancellor Fernando C. Sanchez, Jr. stressed the importance of the role of REPS in transforming UP into a world-class research university and he encouraged everyone to cultivate linkages with fellow REPS to foster interdisciplinary research. This year’s conference was in collaboration with the UPLB Office of the Chancellor and the Office of the Vice Chancellor for Research and Extension.

UPLB, ICHARM and Tohoku University field visit to Candaba, Pampanga

Pampanga RiverPampanga River servicing irrigation of rice fields in Brgy. San Agustin, Candaba, Pampanga.

International Center for Water Hazard (ICHARM), Tohoku University, Kyoto University and University of the Philippines Los Baños conducted a field visit in Candaba, Pampanga last March 11, 2018 Pampanga to gather initial data on the extent of water-related disasters and community disaster risk-reduction plan. ICHARM Director Toshio Koike, Tohoku University Agriculture Crop Modeling Professor Koki Honma and UPLB Interdisciplinary Studies Center for Water Chair Dr. Patricia Ann J. Sanchez met with barangay officials and several farmers of Brgy. San Agustin and Pangclara to discuss farming practices and disaster occurrence in their locality.

During the months of August to December, flooding occurs in Brgy. San Agustin, according to Brgy. councilor Cristopher Culala. Most of the flood volume came from Nueva Ecija and Aurora and drains to Candaba. On the other hand, during strong typhoons, water overflow from Pampanga River causing head-deep flooding in the area. During threats of flood occurrence, the barangay DRRM plans to deploy mobile patrols to warn residents. Each house also has a small fishing boat which serves as their transportation during flood events in their barangay.  

A similar situation is experienced in Brgy. Pangclara wherein water in Candaba swamp reaches 6 feet and knee-deep in the surrounding rice field during rainy season which lasts for the whole duration of the season according to Brgy. Captain Enrique Calma.

Prof. Honma profiled farming practices of the two barangays. Both barangays relies on two livelihoods, which are season dependent. San Agustin cultivates rice during dry season (November to June) and shifts to aquaculture during wet season (July to October). Brgy. Pangclara encounters a similar situation wherein farm lands cultivated for rice and watermelon production are utilized as duck breeding grounds during rainy season as an alternative livelihood. Sabog tuyo, a farming technique wherein seed broadcasting is done during the onset of rainy season succeeded by fallowing, is an emerging adaptation mechanism from intensified dry season practiced by the farmers.

Japanese Professor at SESAM to talk about geohazards

DSC 9015aDr. Kohki Yoshida, Professor from Shinshu University, said natural disasters in Japan are caused by its geological setting.

A geologist from Japan said that the geohazards they experienced in their country is not different the Philippines. Dr. Kohki Yoshida, Professor at the Department of Geology, Shishu University, Matsumoto, Japan visited the School of Environmental Science and Management (SESAM) to talk about the Geology and Geohazards in the Japanese Islands on March 15, 2018.

Dr. Yoshida, a geologist, with expertise in sedimentary geology, sedimentology, geochemistry and paleopedology, has research interests in the Himalayas and Oman mountains, including its weathering and monsoon history; chemical weathering and landslides; and its Triassic mega-monsoon climate records.

Shinshu University, according to Dr. Yoshida, is located at Nagano Prefecture in Honshu Island, near the Japanese Alps, where he studied quaternary rocks. He said Japan has a complex geological history and suggest that the islands were formed in an arc setting in the marginal part of the continent from the Paleozoic period. The island arc setting, which is produced by subduction of oceanic plate and collision of two island arcs, bring active volcanism and big earthquakes to inland and offshore fault activities. He said that the sudden eruption of Mt. Ontake in 2014, and just recently, eruptions of Mt. Kusatsu-Shinare and Mt. Shinmoedake, shows that Japan has an active geology.

Based on his study, the Japanese Islands is a volcanic arc from the Mesozoic to the present. Towards Japan, the Philippine Plate moves 2.5 cm per year, while the Pacific Plate move 8.5 cm per year. “The probability of being hit by a big earthquake is high in the Pacific side of the Japanese Islands due to the movements… Tokyo, Nagoya and Matsumoto show 26 to 38% probability in the next 50 years”, Dr. Yoshida said.

“It is important to discuss with citizens across academic boundaries, we have carried out many activities to consider disaster prevention so far with various generations”, Dr. Yoshida stressed.

Dr. Yoshida pointed out that in terms of preparedness, Japanese people are very familiar with disasters that happens year-in and year-out. “Similar to the Philippines, we also have typhoons, heavy rains, frequent earthquakes and volcanic eruptions, and our people knows the history of natural disasters that happens in their respective vicinities”, he added.

He also took the opportunity to invite SESAM faculty, staff and students to attend the symposium “How to live with nature” in Matsumoto City, Nagano Prefecture, Japan on March 2020. He said Shinshu University started a project for the improvement communication skills in science and technology.  It aims to create communities in which people from different cultural backgrounds and generations to discuss the way we should live with nature. Dr. Yoshida encouraged students to present researches in natural hazards on the upcoming symposium.
