Information about SRI initially came to the Philippines through several paths. The International Institute for Rural Reconstruction (IIRR) took an early interest in SRI after Norman Uphoff visited its center in Cavite in 1997. In June 1998 it hosted a national NGO seminar on rice, cosponsored with ILEIA, and CIIFAD supported participation by Justin Rabenandrasana, secretary of Association Tefy Saina in Madagascar, to introduce SRI to NGOs in the Philippines. ILEIA invited Rabenandrasana and Uphoff to provide an article on SRI for its newsletter. The CIIFAD website also provided information on the innovation. In 1999, the Consortium for Development of Southern Mindanao Cooperatives (CDSMC) conducted its first trials in Mindanao that resulted in 4.95. t/ha, a substantial increase from the usual yields of 1.5-2.5 t/ha. Adaptation of SRI concepts to upland rice production were then made by Broader Initiatives for Negros Development (BIND) based in Bacolod City. It conducted trials adapting SRI to upland conditions in Negros between 1999 and 2002, with results for some spacings averaging over 7 t/ha.
After the director of the Agricultural Training Institute (ATI) in the Department of Agriculture learned about SRI at a conference in Indonesia in 2000, the ATI center in Southern Mindanao undertook trials that averaged over 7 t/ha in 2001 and 12 t/ha in 2002. In 2004, the Cotabato ATI center reported even higher SRI yields. The International Rice Research Institute (IRRI) at Los Baños, however, reported a disappointing yield of only 1.44 t/ha in its 2003 trials followed by a yield of 3 t/ha in 2004. The Philippine Rice Research Institute (PhilRice) trials similarly did not report significant increases with SRI.
Engr. Carlos Salazar, at the time a Regional Irrigation Manager in eastern Mindanao for the National Irrigation Administration (NIA), undertook experiments on his own farm that resulted in yield of 6.9 tons in 2003, 8.9 t/ha in 2004, and 9.6 in 2005. His adaptations, called "Sustainable System of Irrigated Agriculture" (SSIA), are included in a World Bank Institute instructional video (right). SRI trials in 2005 at Visayas State University’s Farm and Resource Management Institute (FARMI) in Baybay City on the island of Leyte, registered SRI yields of 10.16 vs. non-SRI yields of 3.48 t/ha. PRRM has worked with the NGO Save the Ifugao Rice Terraces Movement (SITMO) in promoting SRI in the Ifugao Terraces, a UNESCO World Heritage site, with positive results for for several years. Reports of trials by a number of NGOs and government agencies as well as university research by graduate students and faculty at University of the Philippines at Los Baños and other universities are covered in a 2004 report by Roberto Verzola. (Several UPLB master's theses are listed in the articles section below).
In 2002, SRI-Pilipinas, a consortium of farmers' groups, civil society organizations, academics, and government researchers began functioning and initiated an on-line community that continues to expand. A series of national SRI workshops hosted by the Philippine Movement for Rural Reconstruction began in April 2002, with follow-up workshops in March 2003 and March 2004. SRI-Pilipinas subsequently launched a nationwide training program on SRI principles and practices, funded by the Department of Agriculture through the Philippine Rural Reconstruction Movement (PRRM). According to Roberto Verzola, the SRI-Pilipinas Network as of 2009 had held 50 trainings in 49 provinces throughout the Philippines which benefited an estimated 1,000 farmers. Between 2010 and mid-2012, SRI-Pilipinas has conducted around 120 trainings nationwide, each training attended by 20-25 farmers (see map below). During 2011-2012, the NGO PASALI, which has been promoting SRI in Mindanao since 2006, was selected to be the Department of Agriculture's service extension provider for SRI in that part of the country. During 2013-14, SRI-Pilinas carried out a contest for organic SRI production. During 2014-2015, the Department of Agrarian Reform, along with other local partners, has been active in promoting SRI in both Zamboanga del Sur and Zamboanga del Norte. A Philippine delegation attended the SE Asia Regional SRI Conference held in Malaysia, May 26-28, 2015, and participated in planning for a SE Asia Regional SRI Network along with other national SRI networks in SE Asia. [See "progress and activities" below for news about various NGOs undertaking SRI in the Philippines.]
- AGREA Supports Season-Long SRI Training for Five communities in Marinduque
[February 2017] AGREA Philippines, a social enterprise and foundation, has been making progress with promoting SRI and other agroecological activities on the island of Marinduqpe in the Philippines. A recent video about Cherri Atilano, AGREA's founder and president, is available in the series on ASEAN's Nest Generation Leaders.
During 2016, AGREA began working closely with the Department of Agrarian Reform (DAR) Marinade Office and the SRI-Pilipinas Network in the implementation of a season-long System of Rice Intensification training in Marinduque, Philippines. Demonstration farms are being set up in five rice farming communities in Brgy. Cawit in Boac, Brgy. Napo and Brgy. Baliis in Sta. Cruz, Antipolo, Brgy. Malibago in Torrijos, and Brgy. Malbog in Buenavista. According to Venancio Garde, SRI Pilipinas trainer for this season-long program, "SRI increases the rice yield by a great margin, 20% or more.... When they try SRI and earn from it, there is no going back." Atilano added, "We are replicating effective farming systems so that we can create food security in the island. It all boils down to this: When there is food security, there is food sovereignty. There will come a time when all the food consumed in Marinduque are farmed by Marinduque farmers." According to Senior Agrarian Reform Program Officer Ella Orilla, DAR supports the SRI program as it demonstrates viability of SRI organic farming, and "to establish income generating projects for our beneficiaries, to develop important organic farming skills and to promote self-reliance for our farmers." SRI has been identified as a solution for climate and disaster risk resiliency.
- Pasali Back in Action with System of Rice Intensification Training in Sultan KudaratLa Union Province Gets Recognition for Organic SRI Efforts
[September 26, 2016] Pasali's Extension Service Provider team recently conducted a three-day training on System of Rice Intensification (SRI) methodologies August 30 to September 1, 2016, at Pasali Learning and Resource Center in Barangay Baliango, Palimbang, Sultan Kudarat. The training, which was attended by 31 farmers from different barangays of Palimbang, was intended to promote SRI as climate-smart agro-ecological methodology for increasing the productivity of rice by changing the management of plants, soil, water and nutrients. According to the article on Pasali's website, the training fits with the government’s plan to attain rice sufficiency within the first two years of Duterte Administration. The training was facilitated by Prof. Mansueto Cuaton from the Mindanao State University College of Agriculture, who noted that farmers have an opportunity to produce organically grown rice products and traditional rice varieties through SRI. The training was enhance by Pasali's experience with SRI, which which began in 2005. Pasali also worked on a number of manual and mechanized weeder prototypes between 2005 and 2011.
[April 2016] A farmer in La Union province, Federico Rullamas, reported that his second season crop of high-value organic red rice not only provided a high market price, but also won him the "Highest Yielder for Naturally Grown Organic Rice Farming" award in 2015. Rullamas (right) recorded a yield of 70 cavans/hectare using SRI using composted chicken manure plus home-made organic sprays which he learned from SRI Pilipinas trainer Venancio Garde Jr. [See January 6 article in Philippine Daily Inquirer and a feature story on Rullamas on the SRI-Rice website.]
An April 14 article on the Philippines Information Agency website, which also covers Rullamas' achievements, further expands on the role of the Aringay municipality's support for SRI extension in La Union. Engr. Benjamin Magno from the the local agriculture office reported that the local government provided four months of seed-to-seed training to the farmers to boost their rice production. Beginning with four farmer-adopters in 2013, there are now 120 farmer-adopters of SRI in eight villages in the municipality. The Aringay government allotted an annual budget of P300,000 (about $6,350) from the development fund to ensure sustainability of the program, which includes provision of training, assistance in the production of organic fertilizers and pesticides and equipment. To further educate other farmers regarding SRI, a 1.6 hectare techno-demo farm, in partnership with the Don Mariano Marcos Memorial State University, is expected to be developed this year.
- SRI Progress in Iloilo Presented at National Organic Agriculture Congress in Bacolod City
[December 15, 2015] Joby Arandela and farmers from the Zarraga Integrated Diversified Organic Farmers Association (ZIDOFA) in Iloilo, Philippines, who have successfully y grown indigenous rice varieties with System of Rice Intensification (SRI) methods this season, manned an SRI booth (right) at the National Organic Agriculture Congress in Bacolod City, Negros Occidental. This event, which included an exhibition and trade fair, was held November 25-29, 2015. Visitors to the booth were reportedly so impressed by the differential and profusely-tillering SRI plant specimens (left) that many begged to buy ‘SRI seed’ for themselves. This gave Joby and the Iloilo farmers at the event an opportunity to explain that the difference was not due to the seed used, but to the management methods employed. Several attendees from Mindanao who were already practicing SRI joined the Iloilo farmers at the booth to help explain SRI to curious attendees. One of the four rotary weeders on display was bought by the Vice Governor of Surigao Province since he was intending to introduce SRI to farmers there. There was interest from organic businesses as well as organic farms in the Iloilo rice as well as requests to provide SRI training to farmer groups in other regions.
Participation in the Congress led to additional invitations and attendance at events by Joby and ZIDOFA during December: participation in a National Exhibition on Agricultural Mechanization, December 1-3, a Regional Agri-Aqua Trade Fair and Exhibit in the province of Antique, December 6-12, and the Central Philippine University Climate Smart Agriculture and Organic Trade Fair. [See Arandela's report for details. There is also a video on how the Zarraga farmers produce SRI.]
- Caritas Project SRI Farmers in Samar Report Successful Yield Despite Water Shortage
[November, 2015] Although the El Niño phenomenon has been affecting parts of the Philippines with season-long droughts, rice in SRI fields is successfully being harvested in Marabut and Basey on Samar Island, Philippines. Farmers associated with the Caritas Czech Republic project being implemented by Diocese Social Action Center of Calbayog (DSAC) have gained knowledge how to plant resilient, organic rice with less water. By using SRI methods, the beneficiaries reportedly are among the few farmers able to harvest rice in rainfed areas in Samar. SRI methods are being used to promote organic farming and encourage local production of organic fertilizers in Samar. For more information, see the Philippines page of the Caritas website.
- Five-Month Organic SRI Training in Zamboanga del Norte Province Concludes
[October 22, 2015] Separate graduation ceremonies on October 21 and 22 marked the successful conclusion of the five-month season-long training on "Organic Rice Farming Using SRI" in the towns of Siocon and Sirawai, both in the province of Zamboanga del Norte. Town mayor Julius Lobrigas attended the October 21 ceremony in Siocon, and town mayor Gamar A. Janihim attended the October 22 ceremony in Sirawai. Officials of the Department of Agrarian Reform were present in both ceremonies, as well as the national coordinator Roberto Verzola and regional coordinator Adelberto Baniqued of SRI Pilipinas. Displayed during the ceremonies were sample rice plants that produced as many as 63 tillers from crop cuts that suggested yields of 6 tons/ha in some trial plots up to 8 tons/ha in other trial plots. During the ceremonies, farmers happy and surprised at the results, having attained them with lower costs and without chemical inputs.
- Philippine Delegation Attends SE Asia Regional SRI Conference in Malaysia
The Southeast Asia Conference on the System of Rice Intensification (SRI), held May 26-28 in Alor Setar, Malaysia, was attended by four participants from the Philippines: Dr. Carmelita Cervantes of the Central Bicol State University for Agriculture (Pili, Camarines Norte) and SRI Pilipinas coordinator for Bicol, retired director Adelberto Baniqued of the Department of Agrarian Reform Region 9, currently SRI Pilipinas coordinator for Western Mindanao, Lala Pablo of the Rice Watch Action Network (RWAN), and Roberto Verzola, SRI Pilipinas national coordinator. Verzola, shown at right demonstrating his planting technique at the SRI Lovely field visit, made a presentation on the SRI Pilipinas experience in promoting SRI. Baniqued and Pablo also made presentations on their activities. Cervantes attended the special session on the multi-country SRI-Rice arsenic project, which she is taking part in. The Philippine participants were present at the side events for SRI equipment development, the SRI Global Research Network, and a meeting on the final day of the conference to begin creating a SE Asia regional SRI network.
- 120 Farmers Finish 3-Month SRI Training in Zamboanga del Norte Province
[May 15, 2015] According to an article on the Department of Agrarian Reform website, about 120 agrarian reform beneficiaries (ARBs) in Zamboanga del Norte are graduates of the System of Rice Intensification (SRI) training offered by the Department of Agrarian Reform (DAR). DAR Regional Director Felix Aguhob, who said the course aims to train ARBs in increasing the production of organic rice, also noted that while labor intensive, the yield with SRI is double the normal rice yield. The three-month intensive training was simultaneously conducted in the four barangays of Dipolog City namely Barangays Olingan, Punta, Turno and Gulayon. Farmer are expected to share the SRI methods with other farmers to increase their productivity. Mayor Evelyn T. Uy emphasized the importance of team work and dedication of the people behind the implementation of the Intensive Training for Organic Rice Production through SRI.
SRI Regional Coordinator Adelberto Baniqued was involved in teaching farmers how to apply the new knowledge gained from the training on farms. The SRI training started on December 9, 2014, to March 24, 2015 and was implemented under the DCS3 Expanded Agrarian Reform Community. [...more]
- 90 farmers finish season-long field school in the Province of Zamboanga del Sur
[April 4, 2014] According to a Philippine Information Agency article, on April 3, 90 farmers from barangays Rizal, Miligan and Culo Agrarian Reform Communities (ARCs) of in the municipality of Molave finished a season-long Farmers' Field School (FFS) on Organic Rice Production with SRI. The program was a joint undertaking of the Department of Agrarian Reform (DAR) Agrarian Reform Communities Programme 2 (ARCP2) Agri Enterprise Development Component (AED) and the local government unit of Molave through its Municipal Agricultural Office. Prior to the graduation ceremonies, a group of dignitaries and other guests led by SRI Pilipinas Coordinator Roberto Verzola, DAR officials headed by Provincial Agrarian Reform Officer II Arturo Soria, municipal officials and the farmer-graduates visited the different SRI trial sites in the above-mentioned barangays.

- Farmer Stories Bring to Light Progress in the Fields of Luzon Province
[March 31, 2014] Success with SRI come from a variety of sources in the Philippines. A recent article by Roberto Verzola tells of the story of Julita "Kit" Colcol, a farmer from Sta. Cecilia, Aringay, La Union, who explained to participants of a rice production workshop how she personally came to understand the principles of SRI. Comparing the practices to raising children, Kit (at right in blue shirt) was able to see the value of reducing competition for resources by focusing on single seedlings and their early healthy establishment. She obtained a yield of 6.7 tons/ha this year, a 40% increase over what she was harvesting before trying out SRI. (See Verzola's article for details.)
Climate resilience: Felix Sarte, a rice seed grower from the municipality of Limay, in Bataan Province, discussed resilience of his SRI-grown plants with Roberto Verzola (see photo set). As seen in the photo at left, the non-SRI fields on the left has lodged after high winds, while the SRI field did not. Sarte reported that the thick and deep roots that rice plants develop when they go through a series of wet-dry spells (also called intermittent irrigation, or alternate wetting and drying) help the plants in a number of ways. During the dry spells, the plants send out more roots to search for water. As the upper part of the soil dries, and the water level goes down, the roots grow towards the water. Thus, they go deeper. With thick and deep roots, he says, the rice plants withstand strong winds, flood water and typhoons better. They can also survive droughts longer, because they can find more moisture in deeper soil. (John Vidal also mentions SRI in relation to climate change resilience in his March 31 article in the Guardian's Global Development blog.) This makes SRI a great adaptation measure for coping with extreme weather events and other climate change impacts.
Weekend farmers: Other recent interesting success stories in the Philippines come from the "weekend farmers," who leave their jobs in the city at the end of the work week to try out innovative rice practices in their hometowns in the provinces. Recent interviews with two of these innovators, Joey Tolentino and Eddy Pedroso Canyuto can be found in our SRI interviews playlist. Dr. Tolentino was able to harvest an amazing 16 tons/ha on his farm in Nueva Ecija! (Thailand has a very active "weekend farmers network." We hope they will have a chance to meet their colleagues in the Philippines someday!)
- First Crop Cuts of the 100+ Participants in SRI-Pilipinas' SRI Contest Completed in Camarines Sur
[September 9, 2013] At least 115 participants have entered the organic SRI contest that is ongoing throughout the Philippines. Representatives from the Department of Agriculture, the village government unit, and SRI-Pilipinas were present to supervise the competition's first crop cut, which took place in Camarines Sur Province on September 9. Contestant harvests will continue every few days until contest competition deadline on December 15. The second round with begin during early 2014. SRI-Pilipinas will announce the officially verified SRI record high after the second round; all yield measurements include at least 4,000 sq. According to Roberto Verzola, the contest target is to set the Philippine record for rice yield .... and keep it.
- New Pilipino Language Book on SRI Available from SRI-Pilipinas
[July 1, 2013] A 137 page book on the System of Rice Intensification is now available from SRI-Pilipinas for P300 including shipping. Written in Pilipino, Ang Sistema sa Pagpapalago ng Palay is for farmers, cooperatives and other groups interested in SRI methods. Group trainings and free primers are also available to individual farmers by texting Roberto Verzola at (0939) 1178999.
- SRI Pilipinas Announces System of Rice Intensification (SRI) Contest
[April 9, 2013] SRI Pilipinas, the national SRI network in the Philippines, announced its intent to hold a friendly contest for SRI rice farming beginning in June 2013. The competition, which includes categories for high-cost irrigated, low-cost irrigated, and rain-fed plots, will consist of two rounds:
- Round 1 will be held in the second cropping season of 2013 (June - Nov. 2013). This qualifying round will select the highest-yielding entries from three categories of small-scale SRI trials (in plots of 100-500 m2). The selected entries qualify for the second round.
- Round 2 (the second and final round) will be held in the next cropping season (the 2014 dry season for irrigated, and the 2014 wet season for rain-fed). This round will select from production-scale SRI trials (in fields of at least 4,000 m2) the five highest-yielding entries in each category, who will be declared the contest winners.
The top five winners in each category will receive cash prizes ranging from 1,000 to 20,000 pesos. Any rice farmer (farm owners, tenants and farm workers) in the Philippines is welcome to join. SRI trainers will have a separate category. (Details are available by contacting the SRI Pilipinas Hotline: 0939-117-8999). Participants will receive free training materials and lessons so that they may follow the recommended SRI principles and practices and avoid practices that would disqualify them from the contest. SRI Pilipinas will hold a free seminar (no hands-on) or training (with hands-on) for at least ten contestants (a partnership counting as one) who request such a service.
- Cambodian Rice to Be Exported to Philippines - SRI Cited as Contributor to Increased Production
[April 7, 2013] A recent mb.com.ph article reported that the Philippine government signed a memorandum of agreement (MOA) on rice trade with the Kingdom of Cambodia to pave the way for the National Food Authority (NFA) to import rice from that country for the next two years. The MOA opens the way for the NFA to import rice from Cambodia through Green Trade, a Cambodian public enterprise. The article further reports that Cambodia’s success in rice farming can be attributed in large part to the Cambodian Center for Study and Development in Agriculture (CEDAC), an NGO that has promoted SRI methods since 2000. Between 2002 and 2010, Cambodia’s rice production ballooned from 3.82 million tons to 7.97 million tons. Y.S. Koma, CEDAC's Director, was given the prestigious Ramon Magsaysay Award last year for his contributions to farming technology in Cambodia. Over 100,000 Cambodian rice farmers are reportedly now using SRI, which dramatically cuts down on the use of agrochemicals.
- SRI-Pilipinas Begins Mapping Trials of SRI Farmer-Adopters
[June 25, 2012] Between 2010 and mid-2012, SRI-Pilipinas has conducted around 120 trainings nationwide, each training attended by 20-25 farmers. Usually a training includes a demo SRI trial on a small plot, so most trainings also involve one SRI trial (and therefore one adopter, the farmer who provided the plot where the demo trial is conducted).
The interactive map at right, constructed by Roberto Verzola during May 2012, pinpoints resource persons as well as locations of individual trials by farmer-adopters in Luzon and Mindoro who first tried SRI after requesting and receiving the SRI-Pilipinas primer. The map at left shows these locations for the Visayas and Mindanao. (Click on the blue icons for farm names and white icons for trainer locations.) SRI trainers, and the trainings are gradually being added in, so be sure to check for updates in the near future.
- SRI-Pilipinas Reports on the 2011 Progress by National SRI Training Project
[January 2012] SRI-Pilipinas' 2011-2012 National SRI Training Project is currently underway throughout the Philippines with the assistance of Oxfam Great Britain. A National Evaluation/Planning Workshop/Conference was held on July 29-31, 2011, at the Department of Agriculture, Quezon City, followed by a smaller meeting that was held on November 10-11, 2011, for Mindanao trainers.
One hundred one-day SRI trainings were planned for 2011-2012. As of January 2012, trainings by 13 trainers in 24 municipalities in 12 provinces had been carried out.
Through the National SRI Training Project, which also supports research on SRI, SRI-Pilipinas is currently collaborating with researchers and students at the University of Southern Mindanao, Kabacan, and Western Mindanao State University. Discussions on supporting collaborative SRI research are also underway at Central Luzon State University, Visayas State University and the University of the Philippines at Los Baños.
Since August 1, 2011, SRI-Pilipinas has distributed, through the operation of its SRI Hotline, more than 600 copies of the SRI Primer. Sixty copies of the SRI video and around 30 copies of an SRI Book were also distributed. As in the previous year, the primers were distributed to farmers who texted their name and address to the SRI Hotline (0939-117-8999); the videos where sent by courier to those farmers who, after receiving the primer or engaging the Hotline in conversation, decided to actually try SRI out in their rice field. The SRI Book is primarily provided to government officials, academics, and other individuals and institutions.
Of 636 SRI Primers distributed, 41.3% of those who confirmed receipt of the booklet said they will try SRI, and 15.4% actually tried it. The SRI Hotline has proven itself a viable supplementary tool for social marketing among the least privileged. A Bisayan language SRI Hotline is being considered and if successful, other languages may follow.
- PASALI Advances SRI Extension in Mindanao
The NGO PASALI, which began promoting SRI in 2006, is now officially partnering with Catholic Relief Services for the extension of SRI trainings in Mindanao, particularly Sultan Kudarat. PASALI's Tagalog-language SRI manual is now online as are two 2010 videos showing weeders technical staff are involved in developing and testing for the NGO's projects (see motorized weeder and 12V battery drive motorized weeder videos).
According to Shane Pulmano, PASALI has been selected to be the Department of Agriculture's service extension provider for SRI and is awaiting the official seals of this partnership, which should translate into extension of SRI into more areas as well as closer ties with the government agriculture programs. He also noted that the NGO Rural Development Institute of Sultan Kudarat (RDISK), who undertook a 2010 SRI training with PASALI, has recently received Oxfam support for promoting SRI in RDISK's Mindanao projects.
Additional Mindanao news: A Sun Star article reported that SRI was included in the First Mindanao Organic Farming Congress, held Feb. 19-22, 2012, in Dumingag, Zamboanga del Sur.
