- INDONESIA: ‘ Rice Aplenty in Aceh’ as reported in CARITAS NEWS Australia, Spring 2009 SRI methods were introduced in Aceh in 2005 by CARITAS after tsunami had devastated the area. New methods raised local rice yields from 2 t/ha to 8.5 t/ha: “Using less rice seed, less water and organic compost, farmers in Aceh have quadrupled their crop production.”

- “ Everyone cites India’s Green Revolution. But I’m even more intrigued by what is known as SRI, or system of rice intensification, and I know this is also an area of interest for [Prime Minister] Manmohan Singh. Using smart water management and planting practices, farmers in Tamil Nadu have increased rice yields between 30 and 80 per cent, reduced water use by 30 per cent, and now require significantly less fertilizer. This emerging technology not only addresses food security, but also the water scarcity challenge that climate change is making all the more dangerous. These are all lessons for our world.” Robert Zoellick, President, World Bank Hindustan Times , December 2, 2009
- … our development of farming should shift from the Green Revolution where although harvest production is increased there is also the introduction of damage in many sectors of the environment. We should instead apply methods of increasing the productivity [that are] friendly to the environment. … this SRI method is a proven example where the agriculture is sustained … together with other efforts for preserving the ecosystem, among others, this SRI method of rice farming will really contribute towards saving our planet, our world, and our country. Dr. S. B. Yudhoyono, President, Republic of Indonesia, SRI Harvest Festival, Cianjur, West Java, 7/30/07

- Picture provided by Dr. Koma Yang Saing, director, Cambodian Center for the Study and Development of Agriculture (CEDAC), September 2004. Dr. Koma himself tried SRI methods in 1999, and once satisfied that they worked, got 28 farmers in 2000 to try them. From there the numbers have increased each year, to 400, then 2100, then 9100, then almost 17,000. Over 50,000 farmers are expecting to be using SRI in 2005. Ms. Sarim previously produced 2-3 t/ha on her field. In 2004, some parts of this field reached a yield of 11 t/ha, where the soil was most ‘biologized’ from SRI practices.
- This is the most simple description of what SRI entails. Transplanting is not necessary since direct seeding, with the other SRI practices, also produces similarly good results. The principle of SRI is that if transplanting is done , very young seedling should be used, and there should be little or no trauma to the young plant roots. These are often ‘abused’ in transplanting process, being allowed to dry out (desiccate), or are knocked to remove soil, etc.

- Figures from a paper presented by Dr. Tao to international rice conference organized by the China National Rice Research Institute for the International Year of Rice and World Food Day, held in Hangzhou, October 15-17, 2004. Dr. Tao has been doing research on SRI since 2001 to evaluate its effects in physiological terms.

- Tefy Saina is more comfortable communicating in French language, but it can communicate in English and reads English very well. CIIFAD maintains worldwide contacts on SRI through the internet. Queries are invited, directed to CIIFAD generally or to Norman Uphoff specifically. The SRI web page maintained by CIIFAD in cooperation with Tefy Saina has recent information on SRI experience in countries around the world.
