In: UA Magazine no. 19 - Stimulating Innovation in Urban Agriculture

Since agriculture began some 10,000 years ago, it has been shaped and spread almost exclusively by the farmers themselves, and for the most part without the help of scientific research or extension agencies. Farmers came up with ideas, carried out experiments and arrived
at their own conclusions. Innovation by farmers was the way forward: this local innovation, indeed, was the dynamic process that led to the
development of farming traditions.
