intermediate technology( also called appropriate technology) as belonging between the capital-intensive advanced technologies of the ‘West’, driven by large scale production and profit, and the traditional subsistence technologies of developing countries.
yes i did nick most of that from some site. but it seemed pretty good.
basically approriate technology is somehting that is appropriate to the people that are using it ( not giving a tractor to a famrer that cant afford the petrol), it can be knowledge as well . so rotating fields with crops could be seen as appropriate technology.
