Thousands of examples from India and elsewhere have shown that the people at the grassroots, farmers, artisans, mechanics and the like have been relying on their own ingenuity to solve their local problems. In absence of an external aid, the only option left with them is to come up with their own solutions, which, in many cases, may be able to solve similar problems elsewhere.  Since time immemorial traditional communities have been optimally utilizing the available bio-resources for medicinal and other uses. The need is to properly identify such unique herbal practices and innovations, and document them. Apart from preserving bio-diversity and promoting the culture of creative thinking, such documentation serves another very important purpose, which is to preserve fast eroding knowledge about optimal use of bio-resources and of contemporary technological innovations. Scouting or looking for such knowledge/innovations is the first step towards attaining this goal and is undertaken to discover and recognize grassroots innovations and traditional knowledge practices from rural and urban areas. The nature of problems is different in these areas and so is the focus of innovations. But what is worthy of underlining is that even in most developed regions, urban fringe areas, slums and other places, viable and functional traditional knowledge and grassroots innovations can always be found. Local knowledge systems help in seeking solutions to such problems in a spontaneous manner individually or collectively.
