The director of the Center for Studies and Development of Cambodian Agriculture (CEDAC), Dr. Y. S. Koma, first tried SRI methods in 1999 after reading about them in an ILEIA newsletter article. During 2000, only 28 farmers participated in the SRI experimentation. Due to the early successes of SRI, the Cambodian government, especially its Minister of Agriculture, H.E. Chan Sarun, officially started endorsing and promoting SRI in 2005. Since then, SRI has been promoted in all provinces of Cambodia. Subsequently, SRI was included in the National Strategic Development Plan (NSDP) for 2006-2010 to raise productivity in the rice sector, and then in the revised NSDP for 2009-2013.
There are also at least 47 NGOs and development projects involved in promoting SRI in different parts of Cambodia. Since 2004, there is a national SRI secretariat hosted by MAFF's Department of Agronomy and Agriculture Land Improvement with technical support from CEDAC and funding support from GTZ (German Technical Cooperation Agency), Oxfam America and GB, FAO and HEKS (a Swiss NGO). Since then, the Secretariat began playing an important role in coordinating and assisting SRI activities in Cambodia, While the secretariat has been less active during 2010-2013, there are plans to strenthen its role in the near future. (See Koma's 2008 note on proposed strategies to utilize the potential of rice production in Cambodia.)
On August 21, 2009, the Minister of Agriculture directed that SRI is to become a mainstay of the agricultural development for Cambodia. According to Mr. Ngin Chhay, director of MAFF's Rice Department, by the end of 2009 there were 110,530 farmers using SRI methods in Cambodia on 59,785 hectares in 4,534 villages; the average SRI yield was calculated at 3.48 t/ha, about 1 t/ha more than the national average. During the 2010 Annual Conference of the Ministry of Agriculture, Forestry and Fisheries (MAFF), the Minister of Agriculture, H.E. Chan Sarun, emphasized the importance of SRI in his opening speech and the Prime Minister Samdech Hun Sen spoke highly about the benefits of SRI for rice production in Cambodia in the closing ceremony. On July 6, 2010, the Cambodian Ministry of Agriculture, Forestry and Fisheries (MAFF) convened a meeting to discuss setting up a SRI National Advisory Board (SRI-NAB).
CEDAC estimated that as of 2011, 100,000 families in Cambodia have applied SRI through the promotion of the Ministry of Agriculture, Forestry and Fisheries, their own NGO and other NGOs in Cambodia. During 2011, CEDAC promoted SRI to 75,395 families on 24,293 ha of arable area in 2,317 villages across 268 communes in 45 districts of 13 Provinces. As of 2012, CEDAC was reportedly supporting 140,000 farmer families in twenty-one provinces. CEDAC's president, Yang Saing Koma, was awarded the prestigious Philippines-based Ramon Magsaysay Award Foundation, largely for his work with SRI, on July 25, 2012. During the 4th National Farmers Conference (April 4, 2013), Chan Sarun, Minister of Agriculture, Forestry and Fisheries said that national paddy productivity increased from 2.74 t/ha in 2008 to 3.13 t/ha in 2012, with a good part of this increase attributable to wider use of SRI methods. The Ministry reports that at least 101,719 hectares are under SRI crop management, which means 150,000-200,000 households.
CEDAC Hosts Study Tour for SE Asian Countries
[August 10, 2014] The Centre for Alleviation of Poverty through Sustainable Agriculture (CAPSA) in partnership with the Cambodian Center for Study and Development in Agriculture (CEDAC) facilitated a tour for smallholder representatives in Cambodia August 4-9, 2014. Participants included farmers, NGO extension workers as well as government officials from four Southeast Asian countries (Indonesia, Lao People’s Democratic Republic, Myanmar and Cambodia). The educational visit to Cambodia was held as part of the Network for Knowledge Transfer on Sustainable Agricultural Technologies and Improved Market Linkages in South and Southeast Asia SATNET Asia project. The participants, who had been invited based on their lead role in their respective communities, were exposed to good practices and technologies, including System of Rice Intensification (SRI), organic crop production/certification, and rice mill cooperatives. They took part in site visits to the Tramkork District in Takeo Province, Roleaphear District in Kampong Chhnang Province, and Phnom Penh. (See article on UN ESCAP website).
- SRI Project to Help Farmers with Climate Change
A project on System of Rice Intensification (SRI) in the Lower Mekong River Basin (LMB) countries aims to contribute towards the 2015 goal of exporting 1 million tons of rice and alleviating poverty and hunger. The project is led by the Asian Institute of Technology (AIT), sponsored by the European Union (EU), partnered with Food and Agriculture Organization of the United Nations (FAO) and Oxfam America in collaboration with the Ministry of Agriculture, Forestry and Fisheries (MAFF) and is aimed at enhancing the resilience of rain-fed regions facing climate change in severaal LMB countries: Laos, Vietnam, Cambodia, and Thailand. The National Inception and Planning Workshop on S.R.I project was attended by approximately 30 participants from the Department of Rice Crop, SRI Secretariat, NGOs, development partners (AIT, FAO, and Oxfam), and other stakeholders. Three provinces were chosen to be the model for the project: Takeo, Kampong Speu, and Kampot. The project is being carried out in 4 LMB countries with a fund of 3.4 million Euros for the period of five years, starting from January 2013. The objective is to develop location-specific technology using the principle of S.R.I and Farmer’s Field School platform. (See Khmer Times article for details.)
- Best SRI Farmers for 2013 Selected during May 2014
[May 10, 2014] To reinforce SRI dissemination among farmers in Cambodia, CEDAC initiated a SRI national prize open to all rice farmers in Cambodia. During the 2013 rice farming season, 735 farmers registered to participate in the competition. After first round of evaluation at provincial level, 41 farmers from seven provinces were selected as finalists. On 6 May, 2014, CEDAC invited the 23 selected best rice farmers from seven provinces to participate in the final selection. The selection committee consisted of nine people, including three farmer representatives, two representatives from Provincial Departments of Agriculture and the General Directorate of Agriculture, one representative from the Kampong Cham National School of Agriculture, and three representatives from CEDAC.
Three farmers were selected as best SRI farmers 2013: 1) Mrs. Nhem Sovannary, farmer from Po Preahsang village, Ta Pham commune, Tramkak district in Takeo province, yield of 7.33 tons per ha. 2) Mrs. Sarm Huot, farmer from Kantang Rang village, Rungroeung commune, Stong district in Kampong Thom province, yield of 5.6 tons per ha. and 3) Mrs. Voeun Tep, farmer from Bot Tasom village, Rungroeung commune, Stong district in Kampong Thom province, yield of 5.52 tons per ha. The yield achieved by best farmer for a fragrant rice variety was 7.33 tons per ha, while the yield of fragrant rice with non-SRI methods of cultivation is usually around 2 tons per ha. Farmers are often reluctant to grow fragrant rice as the yields are low even though it sells at a higher price. Thus, with SRI, farmers are more likely to grow fragrant rice for the market as they can get higher prices. The first best farmer received 3 cows, the second best farmer two cows, and the third best farmer one cow. The official ceremony to award the prizes will take place in August, 2014. For the 2014 season, CEDAC invites farmers to register for the competition for the ‘best SRI farmer’ award for this year. (See CEDAC article).
CEDAC Hosts Technology Learning Exchange Program with Several Organizations from the Philippines
[November 1, 2013] In order to share SRI experiences with ASEAN countries, CEDAC hosted a Technology Learning Exchange Program in Cambodia from October 21-27 2013, with the RMAF Magsaysay Institute for Transformative Leadership (RMAF-MITL) and Peace and Equity Foundation (PEF) as well as its partner organizations from the Philippines.The program was intended to analyze adoption factors of SRI; compare the research, extension, production and rice marketing aspects of SRI and discuss engagement, capacity-building, incentives and famrer perceptions. Under the mentorship of a CEDAC team, led by Dr. Yang Saing Koma, 2012 Magsaysay Awardee and CEDAC President, the participants visited farmer associations and farmer producers groups in Takeo, Kampot and Kandal provinces.
During these visits, CEDAC staff and affiliated farmers shared their innovations, including SRI and the Social Enterprise (CSE) model. which represent successful solutions that address sustainable agricultural needs and create self-reliant local entrepreneurs in the agricultural sector. CEDAC showed the 11 participants directly how farmers in rural poor communities are able to produce higher yields with minimal input cost. The CEDAC team also discussed building linkages between farmers and the market at visits to a Rice Mill Cooperative (RMC) warehouse and CEDAC shop in Phnom Penh. For next steps the participants committed to form a "Core SRI" practitioner group in the Philippines and expressed their desire to continue working with CEDAC in future learning exchanges with both farmers and young people from the two countries. (See details on the CEDAC website).
- Study of Organic and Basic SRI Results in Cambodia
[April 15, 2013] At a national workshop with 60 farmer-promoters from 10 provinces held April 4, 2013, in Phnom Penh, the NGO CEDAC reported the initial results from an in-depth study being done on productivity and returns for SRI. In the first year of the study, the paddy production operations of 30 farmers in two villages in different districts were detailed over five years (2008-2012), 10 each who used (a) conventional methods, (b) basic SRI, combining organic and inorganic means of fertilization, and (c) fully organic SRI. The rather large differences seen in these two villages for 30 farmers correspond to what CEDAC staff have been seeing and that Cambodian farmers have been reporting for the past dozen years. The table below summarizes the first-year data reported at the meeting.
Sales of rice
Basic SRI management
Organic SRI management
1.2 m-2.9 m
The advantage seen for 'organic SRI' farmers is partly due to these farmers being more serious, energetic and meticulous users of SRI ideas and practices.
- Presentations at the 4th National Farmers Conference
[April 15, 2013] At the closing session of a two-day national conference with 450 participants from the farming community, the Ministry of Agriculture, Forestry and Fisheries (MAFF), and the Cambodian Agricultural Research and Development Institute, Chan Sarun, Minister of Agriculture, Forestry and Fisheries summarized SRI experience in Cambodia. He noted that national paddy productivity increased from 2.74 t/ha in 2008 to 3.13 t/ha in 2012, with a good part of this increase attributable to wider use of SRI methods. He also emphasized the importance of the soil biota, which is an important SRI concept. The Ministry reports that at least 101,719 hectares are under SRI crop management, which means 150,000-200,000 households. SRI yields are 3.2-3.94 t/ha. It is reportedly starting to apply SRI methods to other crops (SCI): sugarcane and a fodder grass. At the conclusion of the conference, when awards were given to farmers in a number of competition categories, Uphoff presented the Minister with a framed certificate from Cornell expressing "appreciation for his leadership in the promotion and understanding of the System of Rice Intensification (SRI) in Cambodia," and the Minister gave Uphoff a framed 'letter of appreciation' for his role in spreading the knowledge and practice of SRI in Cambodia and around the world. In the photo at right, Minister Chan Sarun, Norman Uphoff and Y.S. Koma are shown (from left to right) at the ceremony. [source: Norman Uphoff's trip report]
- Cambodian Rice to Be Exported to Philippines - SRI Cited as Contributor
[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. Over 100,000 Cambodian rice farmers are reportedly now using SRI, which dramatically cuts down on the use of agrochemicals. [source: Norman Uphoff's trip report]
- CODEGAZ Report on SRI Progress in Siem Reap
The French NGO CODEGAZ reported on 2012 progress made together with its Cambodian partner CEDAC on their three-year training program for resource-limited farmers with in six villages of the Siem Reap Province. Under the program, 380 farmers have been trained in SRI methods, market gardening and ecological chicken-raising in order to improve rice yields, diversify their food supply and ultimately increase their financial revenues.
- Yang Saing Koma Wins 2012 Magsaysay Award
On July 25, the Ramon Magsaysay Award Foundation (RMAF) announced that Yang Saing Koma (at left), president of the Cambodian Center for Study and Development in Agriculture (CEDAC), was among the six individuals that will receive the Ramon Magsaysay Award for 2012. The award is given to "persons - regardless of race, nationality, creed or gender - who address issues of human development in Asia with courage and creativity, and in doing so have made contributions which have transformed their societies for the better." According to an article in the Asian Journal, Koma is being recognized for "his creative fusion of practical science and collective will that has inspired and enabled vast numbers of farmers in Cambodia to become more empowered and productive contributors to their country's economic growth."
Fifteen years after Koma founded CEDAC with a team of seven and the help of a French non-government organization, it has become the largest agricultural and rural development NGO in Cambodia. According to information provided by the RMAF, the "linchpin" of CEDAC's success was the introduction of the System of Rice Intensification (SRI), which gradually spread from 28 farmers introduced to SRI in 2000 to 100,000 rice farmers, with a 61% increase in rice yields, reductions in seeds and chemical fertilizers use, and an increase in organic fertilizer use by 85%. In 2005, the Cambodian government officially endorsed SRI as a rice production strategy. Today, CEDAC is reportedly supporting 140,000 farmer families in twenty-one provinces. CEDAC's work has also been credited as a major factor in this increase in Cambodia's rice production from 3.82 million tons to 7.97 million tons between 2002 and 2010. Koma and the other five Magsaysay laureates (who come from the Bangladesh, Cambodia, India, Indonesia, Philippines and Taiwan) received their awards at formal presentation ceremonies held in Manila on August 31. More than 1500 people attended, including President Aquino. He gave public presentations at the the Ramon Magsaysay Center and elsewhere in the Philippines in late August. (More info, see KI-Media article, Koma's RMA profile, and Business Mirror article, Inquirer article, and PhilStar article).

Sothea, Ros. 2008. (March 18) Report from Phnom Penh
[About an Oxfam plan to distribute a video to promote a System of Rice Intensification video, "Do You Speak SRI?," which it produced with the Cambodian Center for the Study and Development in Agriculture, will help farmers implement the method. English translation of report: The aid group Oxfam will distribute a video to promote a system of rice growing that improves yields, as the growing season approaches. The System of Rice Intensification, or SRI, can improve rice yields by 150 percent, the group said Tuesday, creating a larger surplus that leads to more income and farm improvements. At first, farmer Rum Mao did not believe in the new method. But, he said Tuesday, after practicing it, his yields were higher than in the past. He was pleased with the new system, he said, as it allowed him to sell more rice and earn a better living. The group's information video, "Do You Speak SRI?," which it produced with the Cambodian Center for the Study and Development in Agriculture, will help farmers implement the method.]
