In ‘Celebrating People’s Knowledge, Winin Pereira and co-author Subhash Sule, quote Gandhi’s words: “Every man must be his own scientist and every village a science academy” Anyone has the right – and everyone needs to exercise the right – to be a “scientist” or “technologist”, to question the origin of phenomena, to develop new theories and technologies or to modify old ones”.
Warli farmers tried out synthetic fertilisers but soon abandoned them They said that the fertilisers damaged the soil and that larger amounts were required each year. In consequence, they use very little, and then not every year.
Careful use of material resources
Adivasis see no value in the possession of an increasing quantity of material products or in a lifestyle that stresses comfort even at the cost of the environment and justice. Those possessing more wealth than others are expected to distribute their excess among the rest of their community.The awareness of their interdependence on other forms of life makes their approach to solutions eco-friendly; resources are used with restraint, pollution is minimised. Basically this is an acknowledgement of their awareness of the need to be frugal and sparing in their use of materials and resources which are necessary for their survival.
The development of traditional technologies is limited to those which do not produce unemployment or pollute the environment. There is no unnecessary processing of raw materials; the minimum quantity is used and in processing there is no waste, or if there are remnants unused for the basic need, they are used for other essential purposes. A few of the examples given:
- Wood resistant to termites, such as teak, is used for house construction, thus eliminating the need to use dangerous pesticides.
- Timber resistant to the attacks of teredos (shipworms) is used for constructing boats, avoiding the need for coating the wood with highly poisonous chemicals like tributyltin, with the boat also having a longer life.
- The use of banana leaves as dinner plates, making washing up unnecessary and the ‘plates’ themselves serving as food for cows, which in turn produce milk.
- Where banana plants do not grow, plates made of dry leaves of several other trees [ banyan or breadfruit] or even wooden cups and plates have been used.
These isolated groups use a range of plants for medicinal and other purposes, having done a lot of research over time. Over 9500 wild plant species have been recorded as used by bhagats (right) and other tribals for various requirements, of which over 7500 are used for medicinal purposes. In the case of herbal medicines, cures will only be researched for the specific diseases which occur in the traditional scientist’s habitat. S/he cannot test out herbs without patients who need treatment. The scientist is most likely to use the plants growing locally. Only if these fail will s/he look further afield. This could explain the different species used even by neighbouring communities for the same disease.

Most of the activity in this study was carried out by adivasis who conduct research while carrying on their normal occupations, in their fields and homes, mainly using locally available resources. The researchers do not require formal recognition for their work and are happy to see the use of their shared inventions without expectations of any rewards for their efforts. The free dissemination of knowledge is an essential characteristic of the traditional system.
