An article in the New York Times (Dec 31, 2011) describes the growth in organic farms in Mexico that comply with US definitions of organic farming – a ban on use of synthethic fertilizers, hormones, pesticides etc. But Swedish certification of organic also requires greenhouses to use 80 % renewable fuel, and organic milk laws in the US requires cows to spend sufficient time in open pastures. Should organic labels include specifications regarding the type of fuel or energy sources used ? Should the water used be required to be sustainable ? How should the depletion of acquifers due to water shared by multiple farms be precluded ? In general, should organic farming require the associated energy and water use to follow sustainable practices ?
