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 strengthen 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.
Beginning in 2013, the System of Rice Intensification in the Lower Mekong River Baisn (SRI-LMB) project, which is led by the Asian Institute of Technology (AIT) and 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) to enhance resilience of rain-fed regions facing climate change in Cambodia and several other LMB countries. The regional project titled "Sustaining and Enhancing the Momentum for Innovation and Learning around the System of Rice Intensification (SRI) in the Lower Mekong River Basin (SRI-LMB)," works in Cambodia, Laos, Thailand and Vietnam. In Cambodia, provinces include Takeo, Kampong Speu, and Kampot. During 2014, CFPAR, a season-long intensive training on rice production, was implemented by General Directorate of Agriculture (GDA) of Ministry of Agriculture, Forestry and Fisheries (MAFF) Cambodia in collaboration with Asian Institute of Technology (AIT) and Food and Agriculture Organization (FAO). During 2015, CEDAC organized a national and provincial SRI Planter Championship 2015 to raise awareness of SRI principles and to demonstrate effective SRI methods. Winners will be announced in June 2015. A July 2015 article in Paddy and Water Environment concludes that the key factors for improving the degree of SRI adoption (in three rain-fed villages in southern Cambodia) are farmer zeal and careful attention rather than the home-to-plot distance and availability of labor.
- Video on YouTube about Yang Saing Koma, Cambodia's Best-Known SRI Champion
[July 26, 2016] A Khmer language video (right) on the work of Yang Saing Koma, founder of the Cambodian NGO CEDAC and the first person to test and promote SRI in Cambodia, was released on July 26, 2016, on the YouTube's khmer kakasekar channel. (The 17-minute video, which was shown on Cambodian TV, was released in December 2015 on the Kimsarn Ps channel.)
- Study Explores Factors Affecting Variability in Rice Yields in a Rain-fed Lowland Ecosystem in Southern Cambodia
[July 26, 2016] A recent article by Ly et al in the Wageningen Journal of Life Sciences investigated key factors influencing yields in a rain-fed lowland rice ecosystem in Cambodia under farmer’s SRI and conventional management practices (CMP). Variables contributing significantly to yield variation included: number of cattle (access to farmyard manure [FYM]), farmer’s SRI practices, planting density and soil organic carbon (SOC). These four variables explained 39% of variance in rice yield. Keeping other variables constant, rice yields were increased by 14% (458 kg ha−1) by shifting from CMP to farmer’s SRI practices. The change of one unit in cattle (head), hill density (hill m−2) and SOC (g kg−1) results in an increase of rice yield by 5% (153 kg ha−1), 2% (66 kg ha−1) and 9% (289 kg ha−1), respectively. The higher rice yield obtained by transplanting with narrower spacing suggests that the wider spacing recommended by SRI is less advisable in nutrient-poor soil. Although the application of manure did not emerge as a key variable, three out of the four key variables (farmer’s SRI, access to FYM, and SOC) are directly linked to its use. Farmer’s SRI was strongly associated with the use of FYM, and the plots that received more FYM and belonged to farmers with more cattle had higher total soil N. Total soil N was positively correlated with SOC. The results highlighted the important role of livestock in crop-animal integration and the contribution of animal manure to increase agricultural productivity within smallholder farmers on infertile sandy Cambodian soils.
- Paddy and Water Environment Article Assesses Labor Requirements for SRI in Cambodia
[July 22, 2015] An article by Ches and Yamaji in the journal Paddy and Water Environment compared distinct aspects of SRI labor requirements and conventional practices that could potentially lead to more intensive SRI adoption. A household survey and field observations were conducted in three rain-fed villages in the southern part of Cambodia: two in Kampot Province and one in Kampong Speu Province. Findings showed little or no difference between SRI labor requirements and conventional practices. Laborers are in high demand when preparing land and nurseries, transplanting seedlings, and harvesting. Hired labor costs depend on the supply of farmer-family labor and the efficacy of the ‘‘sharing-hand’’ system, not on farming techniques per se. This system helps alleviate hired labor costs, one of the highest cost factors. The findings also indicated that the degree of SRI adoption shows no correlation between the home-to-plot distance and availability of farmer-family labor or hired labor. The article concludes that the key factors for improving the degree of SRI adoption are farmer zeal and careful attention rather than the home-to-plot distance and availability of labor.

- SRI-Lower Mekong Basin Project Holds Regional Review and Planning Workshop in Siem Reap
[June 4, 2015] A regional review and planning workshop (year 2015) for the project Sustaining and Enhancing the Momentum for Innovation and Learning around the System of Rice Intensification (SRI) in the Lower Mekong River Basin (SRI-LMB) was held in Siem Reap, Cambodia, June 2-3, 2015. The workshop's aim was to share the initial learning derived from 60 action research sites, to jointly review project activities undertaken since 2013, and to collect feedback from various stakeholders and feed into the next cycle of action research to strengthen the project actions. (Click on map at right to see project sites). The event was organized by AIT in collaboration with FAO and Oxfam with local support from the General Directorate of Agriculture (GDA), MAFF Cambodia that hosts the SRI-LMB Project office in Cambodia. Participants included project partners, ministry representatives, country coordinators, local provincial coordinators, district trainers and farmer’s trainers from the host country, as well as universities from all four countries involved in the project. The regional review workshop was preceded by a National Review and Planning Workshop in Cambodia, which was held May 28-29, 2015, in Phnom Penh.(See workshop document for details. For more information on the SRI-LMB project, see the project website.)
- SRI Planting Championship 2015!
[May 8, 2015] CEDAC has been working with rice farmers in Cambodia since 2000 to develop and disseminate principles and methods of SRI. As of 2015, there are more than 200,000 rice farmers throughout Cambodia who have been using SRI principles to improve rice production. The best SRI farmers have proved that SRI methods enable farmers to increase their rice yields by two to three times compared to conventional methods while the reducing their requirements for seeds and other inputs. They also report less labor requirement for transplanting rice through improved planting techniques and skills. However, many farmers still complain that using SRI practices requires more labor, and transplanting only good seedlings one by one is complicated and risky.
In order to encourage more farmers to plant rice using SRI principles effectively --especially to transplant only good seedlings one by one-- CEDAC is organizing the first SRI planting competition among SRI farmers, The SRI Planter Championship 2015. The objectives are: 1) to raise awareness among farmers about SRI methods and 2) to demonstrate more effective ways of crop establishment for SRI. The winners will demonstrate how quickly and at what low labor cost SRI crops can be established, and others can learn from the techniques that they have developed and use for themselves.
CEDAC invites all interested farmers to participate in the competition, which will be conducted at two levels, namely, at provincial level and at national level. The best two SRI planters from each province (one man and one woman) will be invited to participate in the national competition. The three winners selected for national SRI planter awards and will receive the following: First prize: 250 USD, Second prize: 200 USD, and Third prize: 150 USD. The competition at provincial level will be conducted between May and June 2015, and the final competition at national level will be conducted around last week of June. CEDAC team in cooperation with the FNN will be responsible in organizing the competition in each participating province and at national level. The winners of the SRI championship prizes will be evaluated based on the performance of farmers in 1) uprooting seedlings and 2) planting them according to SRI principles. The criteria of the evaluation are as follows: - Number of good seedling uprooted during 15 minutes’ time, and - Time needed to plant on 100 m² and the quality of spacing. The standard spacing for the competition is 25 x 25 cm or 16 seedlings per m². CEDAC will organize an official ceremony to announce the winners as part of the national campaign to raise awareness on SRI. The winners will be invited to share their knowledge and experience with other farmers on how to plant rice with SRI methods most effectively. Videos of the national competition will be made for widespread circulation so that other farmers can see and appreciate the winning techniques.
- The Rice Dragon (Niek Srer) Weeder Campaign Continues in Cambodia
[January 2015] During November 2014, the Cambodian Television Network (CTN) broadcast a program on the Rice Dragon (Niek Srer), a weeding tool innovated by women farmers to reduce weeds in rice paddies. Several videos produced by Oxfam also describe the Rice Dragon (Niek Srer) weeder as well as the marketing campaign for it in Cambodia spearheaded by Oxfam to distribute it during 2014. (See Niek Srer Promotion Activities 2014 and No Weed, More Rice). The Rice Dragon was the eventual result of testing begun by the NGO Rachana in 2008. After farmers tried a number of models over the years, the Rice Dragon was finally selected by women farmers as the most effective, user-friendly design. During 2014, a Rice Dragon business model, which was assisted by Oxfam, was drawn up to include local fabricators, distributors (agri-shops, farmer champions) and farmers. The weeders are currently being promoted through radio, newspapers, leaflets, posters, banners, and billboards, as well as through SRI-NGO meeting and workshops.
Sopheavy Ty, Deputy Regional Director for Oxfam America in Cambodia, made a presentation on the Rice Dragon at the Workshop on Crop Production Equipment for the System of Rice Intensification, held at the Asian Institute for Technology (AIT) in Pathumthani, Thailand, on November 1-3, 2014. The Rice Dragon was also on display at the SRI booth at the 4th International Rice Congress, held in Bangkok, October 27-31, 2014.
- Central Farmer's Participatory Action Research Field Day and Closing Ceremony
[December 2014] The Director of Rice Department, General Directorate of Agriculture (GDA), Ministry of Agriculture, Forestry and Fisheries (MAFF) Cambodia, Mr. Ngin Chhay, addressed a closing and certificate award ceremony of Central Farmer’s Participatory Action Research (CFPAR) was held on November 28, 2014. CFPAR, a season-long intensive training on rice production, was implemented by General Directorate of Agriculture (GDA) of Ministry of Agriculture, Forestry and Fisheries (MAFF) Cambodia in collaboration with Asian Institute of Technology (AIT) and Food and Agriculture Organization (FAO). The project is part of EU funded and AIT-led Regional Project titled "Sustaining and Enhancing the Momentum for Innovation and Learning around the System of Rice Intensification (SRI) in the Lower Mekong River Basin (SRI-LMB)," that is working in 10 provinces of four countries: Cambodia, Laos, Thailand and Vietnam. In Cambodia, provinces include Takeo, Kampong Speu, and Kampot.
The field day held at the Agricultural Farmer Training and Research Center in Kampong Speu province marked the closing day of CFPAR and aimed to culminate and summarize the learnings from season long CFPAR activities. The various experiments set up at CFPAR provided opportunity to the farmer trainers to scientifically set-up experiments, collect observations and towards the end analyze the results (right). Concurrently, the farmers have started FPAR activities after the completion of CFPAR training and conduct field experiments. (For more information, see the SRI-LMB article on the field day).
- Japan International Volunteers (JVC) Carry Out SRI Trainings
 Since 2007, Japan International Volunteers (JVC) has promoted ecologically friendly agricultural practices in order to reduce the use of chemical pesticides and fertilizers which have a negative impact on the environment and those living in these areas. JVC has provided SRI training for 343 farmers in 2014. (See Japan International Volunteer Center article for details).
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 several 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).

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.]
