Homework / test English to Spanish Science Agriculture organic farming/organic agriculture

Estimados(as):

Necesito saber si alguien conoce la diferencia entre estos dos términos "organic farming" y "organic agriculture", según IATE los dos términos se traducen igual, de todas maneras busco la diferencia ya que hay párrafos del texto que estoy traduciendo en el que se nombran ambos.

Extracto: Organic agriculture world-wide offers the promise of a future to produce and distribute food and
other farm products in a healthy, ecologically sound, truly sustainable and fair way. The full
benefits of organic agriculture are just now being realized—from ecosystem services to the
provision of healthier food - yet, to reach its full potential organic farming needs to address
many challenges. While organic agriculture has grown in strength and is in the most favorable
position it has ever been in with respect to market conditions, government policies and
international institutional support, it still does not have adequate resources to continue its
expansion.
