First LCLUC in the Philippines

‘CRITICAL MASS.’ Participants and presenters of the NASA LC/LUC SARI conference and training in front of Quezon Hall of the University of the Philippines Diliman. The SARI Conference has brought together the foremost environmental scientists of the world, including Bangladesh, China, France, Germany, India, Indonesia, Japan, Lao PDR, Malaysia, Nepal, Pakistan, Singapore, Spain, Taiwan, Thailand, the US, UK Vietnam, and the rest of South and Southeast Asia under one roof in a six-day talk and training in Quezon City.


NASA holds first-ever science meeting on land cover/land use change held in Metro Manila

THE PHILIPPINES has recently hosted its first-ever NASA Land Cover/Land Use Changes (LC/LUC) and Impacts on Environment in South and Southeast Asia International Regional Science Meeting of the South/Southeast Asia Research Initiative (SARI), which was held at the Richmonde Hotel, Libis, and the University of the Philippines Diliman, both in Quezon City.

SARI was a six-day event, which started May 28, and was comprised of three days of seminars and three days of training for young scientists on the use of remote-sensing methods.

The meeting was attended by hundreds of scientists, environmental experts, and   mosty hail from the Southeast and South Asian region, who discussed on several issues, like the rapid depletion of natural land into converted agricultural and urban zones, including its implications and profound effects on the ecosystem, but most especially the different advanced tools in monitoring these changes, such as the use of satellites for land or water changes, drones for crop and farmland conditions, environmental mapping, and remote air quality monitoring, akin to that of PAGASA’s climate monitoring.

SARI is under NASA’s Earth Sciences Division. The six-day meeting was organized by Krishna Vadrevu, Ph.D. from NASA, with local organizers Mylene G. Cayetano, Ph.D. and Gay Jane Perez, Ph.D., of the Institute of Environmental Science and Meteorology of the University of the Philippines Diliman (UP-IESM).

“This year’s theme of SARI is on the impacts of urbanization and land conversion on the atmosphere, agriculture, and water resources. We’ll also focus on biomass burning, including land-atmosphere interactions, and the urbanization and use of forests and mountain regions,” said Cayetano, who is one of the PH’s foremost experts in air and environmental pollution.

Remote sensing in the PH

But while the Philippines is just starting to nurture its remote sensing capabilities, the pinnacle of which is the Diwata-1 microsatellite, it has no shortage of home-grown environmental scientists and experts.

According to Chris Justice, Ph.D., Chairman of the Department of Geographical Sciences of the University of Maryland, and one of the presenters of the SARI Science Meeting, there is a need to unify scientists from South and Southeast Asia, their data and researches into one repository to develop each country’s capability.

“[The SARI Science Meeting] is a development of a network of scientists on each of the topics here. Yes, they are being studied, but do we have critical mass to advance the science? In each country [of the region] there are few scientists, but combined, they form a critical mass of scientists. The idea of LC/LUC and SARI as a whole is to bring scientists from the region who are working on the same problems and to share their methods and experiences, that way we can help each other.

“It’s not like we do not have regulations [regarding land-use and land use change] in each country. We do have these regulations. However, what we need to achieve is to highlight the issues that these policies revolve on and involve the policy-makers so that they may have a better understanding of them,” said Vadrevu, who is also a professor from the University of Maryland.

IESM 15th Anniversary

A look back on the Department of Meteorology and Oceanography: Before the merger and beyond

The Institute of Environmental Science and Meteorology (IESM) is an academic unit of the College of Science in the University of the Philippines Diliman (UP). It was established in 2003 with the merger of the then Environmental Science Program (ESP) and the Department of Meteorology and Oceanography (DMO). As IESM celebrate its 15th founding anniversary this year, it is nice to look back.

The DMO began in 1968, then called Department of Meteorology. It was established through a World Meteorological Organization/United Nations Development Program (WMO/UNDP) Project and implemented under a UP/PAGASA (Philippine Atmospheric Geophysical and Astronomical Services Administration) Memorandum of Agreement. This year marks its 50th anniversary.

The first class of the course Introduction to Meteorology (Met 101) was offered during the second semester of school year 1967-1968. There were five students:
Eliseo Chan, Evelyn Gomez, Rodolfo (Rody) de Guzman, Theta Ponce and Linda Santiago, all physics majors. (See personal note below).

The class was taught by Dr Jorge G. de las Alas, the first faculty member of the Department of Meteorology. He obtained his Ph.D. in Meteorology from McGill University in Montreal, Canada. Then Dr Dominador C. Canlas joined later. He obtained his Ph.D. from New York University with specialization in Physical Oceanography. It was after his arrival that the Department was renamed Department of Meteorology and Oceanography. Dr Canlas was one of the post-war ‘pensionados’ (‘scholars’) sent abroad by the Philippine government to the United States for postgraduate studies in meteorology and related fields (as part of the post-war reconstruction program which started in the late 1940s). Others in this group were Isidro Cariño, Hugo de la Cruz, Mariano Estoque and Jaime Tecson.

Soon after the Department was founded, there was a position opened for an instructor.  Rodolfo A. de Guzman was recruited in early 1969. He was then granted a WMO fellowship under the WMO/UNDP project. He did his M.Sc. in Meteorology at the University of Reading’s Department of Geophysics in Berkshire, England from September 1969 to June 1970. Then he did his Ph.D., again under a WMO Fellowship, in the same University from January 1977 to May 1980. His postgraduate dissertations were on Tropical Cyclone Movement, Structure and Development. From 1972 to 1975, he was with PAGASA as Project Coordinator of the NSDB/PAGASA Typhoon Research Project led by the PAGASA’s head, Dr Roman L. Kintanar. He also served as a Weather Specialist in the then newly created Typhoon Moderation Research and Development Council (TMRDC). In November 1981, he joined the WMO as Chief of the Fellowships Branch in the Education and Training Department. He worked with WMO for 27 years in various positions, retiring in 2008 as Director, Strategic Planning Office and Special Adviser to the Secretary-General.

DMO offered undergraduate service courses in which students from different fields, including in Environmental Science, enrolled. It also offered M.S., Diploma and Ph.D. programs. It was designated as the University component of the WMO Regional Association V (Southwest Pacific) Regional Meteorological Training Centre (RMTC, later known simply as RTC).  Students from various countries in the Region and beyond came to DMO. Among others, there were students from Burma (now Myanmar), Indonesia, Taiwan and Thailand as well as from Costa Rica and Denmark.

The collaboration between PAGASA and DMO was mutually beneficial. Many senior PAGASA staff served in DMO in various capacities including as professorial lecturers. These included Ellaquim Adug, Jaime Bucoy, Cipriano Ferraris, Hugo de la Cruz and Jesus Flores. On the other hand, many of the current and former senior officials of PAGASA obtained their postgraduate degrees from DMO. This led to improvement of PAGASA’s operational and research capabilities in such areas as typhoon prediction, development of instability indices for thunderstorm forecasting and numerical weather prediction. PAGASA continues to benefit from these earlier developments.

This collaboration with PAGASA continued after DMO was transformed to form part of the IESM. The range of programs and activities has been expanded. It is noteworthy that current set of students come from various origins, geographically and in terms of their earlier disciplines. There is also enhanced support in terms of scholarships including from the Department of Science and Technology (DOST).

Following the approval of Republic Act 10692 in November 2015, PAGASA is embarking in a Modernization Program. It is hoped that this Modernization Program will also redound to the benefit of the IESM and its collaboration with PAGASA. Furthermore, in pursuit of excellence and greater service, IESM and PAGASA may wish to consider additional or strengthen existing strategic alliances such as with DOST, PCIEERD, NRCP, CHED and other institutions. It is a good indication that IESM chairs the Technical Panel for Meteorology in CHED as well as the Consortium for Meteorology Education and Training (COMET).

(PERSONAL NOTE: In the second semester of 1967-1968, the course Met 101 Introduction to Meteorology was first offered. Four physics majors enrolled taking the subject as an elective. As courses were to be dissolved if there were less than five students, Rody de Guzman was approached and encouraged to be the fifth student. Rody asked: ’What is meteorology?’ ‘The study of meteors’ was the reply. The subject was going to be taught at the PAGASA Planetarium located in the UP premises. So, it made sense that it was indeed about ‘meteors’. On the first day, Dr. de las Alas introduced the subject. The five physics majors looked at one another and mouthed the words ‘wrong course!’ The five stayed on anyway. And when the post of instructor for the Department was subsequently opened, the five were priority candidates. And that started Rody’s career in meteorology. This ties up to the alternative form of the saying: ‘To err is human, to forgive divine’; in the form of ‘To err is human, but isn’t it divine?’)
