About IRRI

Los Baños is home to the International Rice Research Institute (IRRI), an autonomous, nonprofit agricultural research and training institute established to improve the well-being of present and future generations of rice farmers and consumers, particularly those with low incomes.

Established in 1960, IRRI performs research and training on rice, and serves as an international bank for rice germplasm. The research center includes laboratories and training facilities on a 252-hectare experimental farm at the University of the Philippines-Los Baños (UPLB) campus.

IRRI generates and disseminates rice-related knowledge and technology of short- and long-term environmental, social, and economic benefit. The institute also helps improve the National Agricultural Rice Research and Extension Services (NARES) of its partner countries.

One of IRRI’s major thrusts is the development of technologies that improve the well-being of farmers and consumers, particularly those with low incomes. IRRI not only offers training and professional advancement in NARES scientists, but also provide an equitable access to information and knowledge on rice, and so helps develop a critical mass of professionals working to advance rice science.

About Los Baños

Los Baños, the special Science and Nature City of the Philippines, hosts different local and international academic and research institutions. It is home to the University of the Philippines Los Baños (UPLB), the country’s premier state university in agriculture.

Located 63 kilometers south of Manila, the town sits on the narrow southern shoreline of Laguna Bay and the northern foothills of the legendary Mount Makiling.

As its name suggests, “Los Baños”, Spanish for “The Baths”, is known for many springs where one can bathe and keep cool.

As scholars and trainees of IRRI, you may either stay at Harrar Hall or at Swaminathan Hall. Other guests may opt to stay at IRRI Guesthouse. The Front Desk is located at the ground fl oor of Harrar Hall (near the staircase). Laundry and housekeeping services are provided in these residences.

At the airport

IRRI GRS staff with 9(E) visas are permitted to use the diplomatic line at the immigration desk, which is often the shortest queue. You will be met by a driver at the Ninoy Aquino International Airport upon your arrival (NAIA) and then transported to IRRI (usually a 2-hour journey). In the airport, you can first pick up your luggage and then pass through customs. Customs officials are aware of IRRI, and luggage checks are usually no problem. After that, you can proceed to the receiving area where an IRRI representative will make himself known. If no one is there, proceed to the International Organizations desk. The agent there will contact the IRRI driver for you. Someone bound for IRRI arrives every day and, even if the driver is late, wait for him.

If you have any problems at the airport, the person at the International Organizations desk can:

  • call the IRRI Manila office at (02) 856-6133 or (02) 856-6129 between 0800h and 1700h, or
  • call IRRI-Los Baños at (02) 580-5600, (02) 845-0563, or 812-7686 after 1700h.

If all this fails, check into any hotel in Manila and call IRRI the following morning. Do not take a taxi to IRRI. An IRRI driver will take you to your accommodations at IRRI.

Upon arrival at IRRI

Please read through the orientation schedule placed in your room. The Family Liaison Officer from Human Resources Services and/or a host/host family will be available to help you upon your arrival. Contact information will be placed in your room or sent to you by email before you arrive. The Family Liaison and the host/host family will try to contact you on the first or second day. They will assist you in learning about IRRI and Los Baños, and introduce you to the community. Feel free to contact them if you need assistance at any time.
