Effective microorganisms (EM) research and application
Context (starting point & circumstances – involved people/unit)
Developed by Teruo Higa in Japan in the 1970’s, EM is a symbiotic culture of microorganisms sourced from nature and human food (lactobactilli, yeast, and phototrophic bacteria).
In Auroville, a variety of actors are engaged in research and applications of Effective microorganisms.
Eco-Pro offers consultancy and training in public hygiene and environmental health. This includes the development and application of EM technology to the various fields of organic agriculture, water sanitation, and treatment of polluted soils and water bodies.
Eco Pro has been extending technical guidance to farms, plantation and industries within Auroville, as well as in Tamil Nadu and neighbouring states.
Discipline Farm, Annapurna farm and AuroAnnam are amongst the Aurovillian Farms using EM, replacing the use of chemicals and pesticides and subsequently increasing the yields and quality of crops, as well as the speed of composting.
Research and development of EM technologies is carried out in collaboration between Eco-Pro, CSR, outreach agencies of Auroville, state and municipal authorities and various NGO’s working on integrated sanitation, decentralized wastewater treatment and solid waste management.
Goal & expected outcome
Through the use of EM, the ratio of positive microorganisms in organic matter is increased. Its applications are in the fields of agriculture, animal husbandry, aquaculture, solid waste management and wastewater treatment. The use of EM is thus a vector for public hygiene and environmental rehabilitation, demonstrated and in use in around 150 countries
The use of EM technology aims at replacing chemical inputs, to achieve eco-friendly and safe practices in food production, hygiene and waste management and hence work towards greater public and environmental health.
