“Let us take full advantage of this occasion in providing a platform that further enhances our regional collaboration so that we could better respond to the risks of climate change,” UPLB Chancellor Fernando C. Sanchez, Jr. urged the participants of the Workshop on Enhancing Climate Change Adaptation in Southeast Asia.  

Chancellor Sanchez made this call to action in his opening message to delegates from Southeast Asian countries and India during the final planning workshop of the project entitled “Enhancing Local Level Climate Change Adaptation in Southeast Asia (Phase 1).”

The workshop, held on Oct. 14-15 at Hotel Jen Manila, aimed to provide the basis for developing the project’s Phase 2.

The project is a collaborative undertaking of the ASEAN-India Green Fund and the Southeast Asia Disaster Prevention Institute of University Kebangsaan Malaysia with 10 ASEAN member states namely, Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand and Vietnam.

According to Dr. Ampai Harakunarak, assistant director-head of the environment section of the Socio-cultural Community Department of the ASEAN Secretariat, “the project aims to conduct a needs assessment and scoping study to identify the needs of ASEAN member states in terms of climate change and develop a regional ASEAN-India work programme and network on climate change adaptation.”

Dr. Juan M. Pulhin, faculty member at the College of Forestry and Natural Resources of UPLB, together with the Department of Environment and Natural Resources (DENR), will implement the scoping study for the Philippines.

During the workshop, Albert Magalang of the DENR presented the results of the climate change needs and priorities in the Philippines while Dr. Pulhin presented the academic perspectives for climate change adaptation. Dr. Pulhin also co-moderated a session on plans in ASEAN climate change adaptation and networking.

Present in the workshop were Filipino delegates Atty. Jonas R. Leones, undersecretary for environment and international environment affairs of the DENR; Dr. Rodel D. Lasco, country coordinator of the World Agroforestry Centre; and Dr. Alfredo Mahar Lagmay, executive director of Project NOAH and a geology professor at UP Diliman.

Dr. Joy Jacqueline Pereira, ASEAN project coordinator, and Prof. N.H. Ravindranath of the Centre for Sustainable Technologies of the Indian Institute of Science, served as workshop conveners.

The workshop was co-organized by UPLB through the Interdisciplinary Study Center for Integrated Natural Resources and Environment Management (IdSC-INREM), UP Diliman through the National Institute of Geological Sciences, DENR through the Environmental Management Bureau, and the Asia Pacific Network for Global Change.

Mario Navasero, Scientist 1 at the Crop Protection Cluster of the College of Agriculture, was declared semi-finalist/regional winner in the 2015 Hero ang Public Servant Dangal ng Bayan Award of the Civil Service Commission (CSC) Region IV. Navasero was presented the award in ceremonies on Oct. 20 at the CSC Region IV office in Quezon City.

This is the second award Navasero received this year, the first being the UPLB Outstanding Researcher Award given during the Foundation Day celebration of UPLB on March 4.

Navasero, along with his colleagues, Marcela M. Navasero and Dr. Bonifacio F. Cayabyab, discovered an encrytid parasitoid, a safe alternative to the use of chemicals to control coconut scale insect (CSI). The encyrtid  parasitiod, which is CSI’s main biological control agent, functions by parasitizing the adult CSI, leading to its not non-reproduction and death.

He has also contributed information on other insect pests such as Brontispa, black army worm, and Spodoptera exempta. Navasero is also involved in the study of non-target organisms for Bt-eggplant. He evaluates and analyzes the risks and attests to the safety of a technology. The information he provides is one of the regulatory requirements in the registration and commercialization of the crop.

He is currently working with one of the biggest exporters of coconut products, helping maintain the organic status of the products by providing biological control solutions to manage pests of coconut in their production sites.

Navasero is a prolific writer and has been conducting original researches that have produced significant findings. He has produced 29 journal articles, three semi-technical papers, two manuals, nine leaflets, 25 papers, 47 posters presented at scientific conventions. He has received eight UP International Publication Awards for his papers that were published in ISI and Scopus-Indexed journals. He was conferred Scientist I rank under the Civil Service Commission in 2013. The Philippine Association of Entomologists awarded him the 2014 L.B. Uichanco Memorial Award as outstanding entomologist.

With Navasero during the awarding rites was Dr. Susan Calumpang, assistant vice chancellor for research and extension, who nominated him for the award.  (Maribeth C. Jadina)
