The campus was established in 1909 on of abandoned farmland at the foot of
Mount Makiling, purchased by the
University of the Philippines (UP) Board of Regents to serve as the campus of the newly created
UP College of Agriculture (UPCA). Students helped clear the land, and the first classes were held in tents. Practical instruction was done at plantations on campus, such as those for corn, sugar cane and tobacco.
Act 2730 of the
Philippine Legislature in February 1918 authorized the appropriation of for the creation of an agricultural experiment station. At the same time, funding of ₱125,000 (US$2,890) Most of the early structures were demolished during the
Japanese occupation of the Philippines (1941–1945), but some still exist, including the Palma Bridge and
Baker Memorial Hall (both built during
Dean Bienvenido M. Gonzalez's term from 1927 to 1938). All the student residences, 23 College of Agriculture buildings, 13 student dormitories and bungalows, and 22 faculty and employee houses were destroyed during the Second World War. The
School of Forestry was also devastated. Only the
agricultural engineering building was left undamaged. Grants from
USAID and Mutual Security Agency in the 1950s accelerated the development of the campus. The
Graduate School building, the UPCA Library (now
College of Arts and Sciences building), and the Women's Dormitory (now the Math Building) were built as a result. Meanwhile, grants from the United States Economic Cooperation Agency (worth US$239,552), the International Cooperation Administration (ICA) (worth US$175,000), and ICA-
National Economic Council allowed the construction of the Forest Products Laboratory (claimed by
Centennial Panorama: Pictorial History of UPLB to be the "largest and best equipped in the eastern hemisphere" at the time it was constructed) in 1954, the Agricultural Credit and Cooperatives Institute in 1957, and further construction of school and dormitory buildings in the School of Forestry campus in the 1960s. funded US$6.9 million for the construction of the
International Rice Research Institute. Beautification projects include paving of pathways and construction of lampposts. Some students criticized the program, arguing that the funds would have been better allocated for the renovation of classrooms, laboratories, and other academic facilities. A memorandum issued by
Chancellor Luis Rey I. Velasco in 2010 instructed UPLB to
conserve energy to reduce operating costs. The plan calls for reduced use of electric appliances (such as air conditioners, electric stoves and ovens),
car pooling, and
recycling. ==Areas==
