"In Pursuit of Innovation, Interdisciplinary Collaboration, Internationalization & Inclusive Development"

Doctor of Philosophy in Environmental Science


Brief Description of the Major Field

The Doctor of Philosophy (Ph.D.) in environmental science is a university-wide interdisciplinary program focusing on theoretical and methodological issues in environmental science and management. Graduates of this program are expected to deal competently with contemporary concerns in environmental analysis, planning and management.

The resolution of environmental problems linking together several disciplines and organizing knowledge to have a holistic view of the factors determining environmental conditions in a given time and place. The ability to integrate biophysical, social and cultural information is crucial in analyzing and resolving environmental problems. The programs aims to sharpen the understanding of contemporary environmental issues and problems using analytic techniques, like case analysis, modeling and simulation.



After completing the program, the student is expected to be able to:

a. Demonstrate an in-depth understanding of the body of knowledge in his/her chosen area of specialization in environmental science.

b. Undertake original and independent research on topics related to his/her area of specialization which would elucidate theories on the resolution of                 environmental problems;and contribute to the body of knowledge and methodologies in environmental science by undertaking quality scholarly work.



For admission to the program, the student must have a Master’s Degree in Environmental Science or a related discipline from any institution of higher learning recognized and accredited by the UPLB Graduate School. To be considered for admission, the student must have a GPA of 1.75 or better ad meet other requirements prescribed by the UPLB Graduate School.


Requirements and Mechanics to Graduate

A student seeking to qualify for candidacy to the PhD degree must have taken and passed any three (3) of the four (4) foundation courses in UPLB.

In addition the student must pass a qualifying examination to be given by a guidance and advisory committee at a time within the schedule of course work prescribed by the committee. To pass the examination, the student must not receive any negative vote from any member of his/her advisory committee before registering in the second semester of residency.

Consistent with the existing rules of the UPLB Graduate School, courses taken in an MS Degree may not be credited in the PhD degree, the core course which had already been taken in MS EnvSci will have to be substituted by other ENS courses. This is to ensure that the student will fulfill the total units required in the program.


Areas of Specialization

Environmental Security and Management– Provides advance training in policy and research methodologies related to the study of environmental impacts and threats to human and other populations, to communities and groups, and to their life-support eco-systems and how these can be regulated and controlled.

Protected Areas Planning, Development and Management– Provides advance training to develop courses in planning, managing and developing protected natural areas.

Social Theory and Environment– Provides advance training in the analysis of human-resource interactions and how these become the bases for designing environmental resource policies and programs.
