When is less really more, and new actually old? The catchwords and tenets of the post-Second World War Green Revolution in farming are fast being replaced in the public mind by those of a counter-revolution, as yet unnamed, whose own vocabulary sounds properly technocratic, but which in fact harks back to traditions that may be hundreds of years old: words like "sustainability," "biodiversity," "integrated systems" and "low-input" now buttress the more familiar "organic farming." But what is everyone talking about, and just how organic is the "low-input" movement? Bradley Busetto asked the International Federation of Organic Agriculture Movements (IFOAM) for its view. IFOAM members Susan Milner, Coen van Bueningen and Boudewijn van Elzakker responded.
