Early History (1908-1930s) UPLB was originally established as the
University of the Philippines College of Agriculture (UPCA) on March 6, 1909, by the UP Board of Regents to promote agricultural education and research in the Philippines. In 1910, the Forest School was established as a branch of the College of Agriculture. By the early 1920s, enrollment had increased to 621 students, representing most provinces of the Philippines as well as several foreign countries, including China,
Siam, Guam,
Java, India, and Japan. This growth placed the UPCA among the larger units of the University of the Philippines during that period.
World War II and Its Postwar Reconstruction (1940s) During the
Japanese occupation of the Philippines, UPCA was closed and the campus converted into an
internment camp for allied nationals and a headquarters of the Japanese army. Only four paratroopers and two
Filipino guerrillas were killed in the raid. However, Japanese reinforcements arrived two days later, destroying UPCA facilities UPCA became the first unit of the University of the Philippines to open after the war, with Leopoldo Uichanco as dean. However, only 125 (16 percent) of the original students enrolled. It was even worse for the School of Forestry, which only had nine students. Likewise, only 38 professors returned to teach. UPCA used its
₱470,546 (US$10,800) share in the Philippine-US War Damage Funds (released in 1947) for reconstruction. Further financial endowments from the
United States Agency for International Development (USAID) and the Mutual Security Agency (MSA) allowed the construction of new facilities, while scholarship grants, mainly from the
Rockefeller Foundation and the
International Cooperation Administration, helped fund the training of UPCA faculty. From 1947 to 1958, a total of 146 faculty members had been granted MS and PhD scholarships in US universities. Dairy Training and Research Institute, and the Department of Food Science and Technology. New facilities were also constructed under his Five-Year Development Program.
Cornell University was instrumental in the post-war rebuilding of UP's Los Baños colleges. The Cornell-Los Baños project, implemented in 1952 to 1960, involved the rebuilding of UPCA's physical plant and Central Experiment Station, procurement of scientific equipment, and upgrading of teaching standards. A similar undertaking between Cornell,
Syracuse University, the
State University of New York, and the UP College of Forestry was implemented between 1957 and 1963. A "sister university relationship" was formally established in 1962 through the UP-Cornell Graduate Education program, which sought to develop and expand UP's agricultural education, research and extension programs, and to strengthen Cornell's own international agricultural development program. The program ended in 1972.
Birth of UPLB’s Autonomy (1970s-1990s) Political and Institutional Challenges The
1969 Philippine balance of payments crisis under the
Ferdinand Marcos government marked the beginning of a prolonged period of social unrest across the country, including in UP Los Baños. This period of unrest, which included the
First Quarter Storm, coincided with another issue, which was the call for the UP College of Agriculture to become independent from the University of the Philippines in Diliman. New colleges and research centers were created over the next few years, while the
College of Veterinary Medicine was likewise transferred to UPLB from
UP Diliman. Following the death of Chancellor Samonte in December 25, 1978,
Dr. Emil Q. Javier succeeded him as the second chancellor (1979–1985), later serving as UP System President (1993–1999). Javier had been instrumental in building the university’s research infrastructure even prior to his chancellorship, notably as the founding director of the Institute of Plant Breeding. In 1983, through Javier’s initiative, Executive Order No. 889 was issued to establish the National Centers of Excellence in the Basic Sciences. The order designated several units within the UP System as national centers to bolster the country's scientific research capacity. At UP Los Baños, this included the Institute of Mathematical Sciences, the Institute of Chemistry, and the Institute of Biological Sciences. Dr. Javier's leadership continued at the system level during his term as UP President (1993–1999). During this period, he led the establishment of
UP Open University and
UP Mindanao, and institutionalized the Ugnayan ng Pahinungod volunteer program. He also expanded the biotechnology program into a network known as the National Institutes of Molecular Biology and Biotechnology (NIMBB), with units across the UP System's major campuses.
Student Journalism Meanwhile, the establishment of UPLB as an autonomous campus also saw the establishment of the UPLB Perspective as its student paper in 1973 – earning it the distinction of being one of the first student newspapers to be allowed to publish after the September 1972 martial law
crackdown on newspapers and other media establishments. UPLB’s graduate programs have also continued to expand across diverse disciplines, with the 2020s marking the introduction of notable programs in environmental management, resilience, and sustainability as well as new “PhD by Research” programs. In 2015, the
Nagoya University Asian Satellite Campuses Institute was established at the Graduate School, offering transnational doctoral programs in various fields. UPLB has also launched Dual Doctor of Philosophy by Research programs with the
University of Montpellier in France, the
University of Reading and the
University of Liverpool in the United Kingdom, and
Curtin University in Australia (in collaboration with
UP Mindanao), allowing students to earn doctorates from both institutions through joint supervision and study arrangements.
Academic Reforms and the Pandemic Years Institutionally, the university responded to national reforms, notably navigating the academic adjustments and student intake gap caused by the implementation of the K-12 Basic Education Program in the mid-2010s. Simultaneously, UPLB adopted the Student Academic Information System (SAIS) for registration, a controversial digital transition that generated significant and sustained student protests due to technical difficulties. During the pandemic years (2020-2021), the UP including UPLB shifted to remote learning and research, mobilized experts and resources to aid the national COVID-19 response. UPLB also established a subnational COVID-19 testing laboratory equipped with an RT-PCR machine, repurposing one of its existing research facilities for this effort.
Recent Campus Development In recent years (2022-2025), the government launched new construction projects in UPLB. These include the construction of a new main library, the Food Processing Research and Development Center, the Agricultural and Economic Development Studies Center, and a microbial bank for the BIOTECH Philippine National Collection of Microorganisms. Construction of the Agricultural Genomics Research Center (AGRC), a collaboration among UPLB,
KOICA, and IRRI, has begun and is set to be completed in early 2026 as a state-of-the-art hub for genome-based research advancing crop and livestock improvement, food security, and capacity building.
Other Notable Incidents Affecting the UPLB Community When
martial law was declared in September 1972, Marcos cracked down on any form of criticism or activism, leading to the arrest, torture and/or killing of Los Baños residents. Those killed included student activists Alexander Mecenas Gonzales,
Modesto "Bong" Sison, and
Manuel Bautista, campus journalists Antero Santos and Alfredo Malicay, and botany teaching fellow Cesar Hicaro. Meanwhile, Chemistry instructor
Aloysius Baes was among those who were
arrested and tortured. Those who went missing ("desaparecidos"), meanwhile, included
Tish Ladlad,
Cristina Catalla,
Gerardo "Gerry" Faustino,
Rizalina Ilagan,
Ramon Jasul, and
Jessica Sales. Violent crime incidents in the UPLB community, with some resulting in the deaths of students (
Eileen Sarmenta and Allan Gomez in 1993, Given Grace Cebanico in 2011, Ray Bernard Peñaranda and Maria Victoria Reyes in 2012) were widely covered by the national media. As a result, national government agencies, the local government of Los Baños, and the university administration have enacted more stringent security measures. ==Organization and Administration==
