EARTH DAY: Farmers Using the System of Rice Intensification are Doing Their Part

Using less water in MaliEarth Day, which falls on April 22 this year, is of course very relevant to SRI! Using less water, less agrochemicals, and less seed to get higher yields can help reduce the growing assault on the earth's resources and environment. The System of Rice Intensification also has a role to play in mitigating climate change by 1) reducing standing water (see photo at left), leading to decreased methane emissions; 2) reducing inorganic fertilizer use, leading to decreased carbon and nitrogen emissions from manufacture of fertilizers and their subsequent transportation over long distances; and 3) sustainable increases in the productivity of existing land, preventing the conversion of carbon sequestering forests to agricultural uses.

In fact, state governments in Tamil Nadu, Bihar, and elsewhere in India are currently promoting SRI, partly due to water savings with SRI.

Of course, benefits are not all related to climate change. Increased yields, another advantage of SRI, have been reported in 50 countries, and, in Kenya, Bancy Mati will soon release research results on how SRI water management breaks the mosquito breeding cycle and shows good prospects for malaria control.

SRI RESEARCH: More Published Articles than You Might Think!

Although System of Rice Intensification (SRI) methods are now being used in at least 50 countries worldwide, there are still skeptics asking, "Where's the scientific proof that it really works?" For those who want a closer look at the science behind SRI, SRI-Rice at Cornell University has collected nearly 250 journal articles about SRI. And, we would like to share our bibliography with the global SRI community and others who would like to know what research is being done and what is being found.

See the April SRI-Rice Feature for information on accessing the SRI journal article citations and database. (Although many research articles are not free, the abstracts are available). There is still much research we haven't found. If you find something not included in our list, please send it out way:!
