The first issue involves the environmental effectiveness of organic farming regulations. Specifically, the question is whether organic standards suffice to reduce the environmental pressure of agriculture or further restrictions are required. This matter is important because both the market and policy-makers consider organic agriculture a more environmentally-friendly food production system. The effectiveness of organic regulation for generating environmental benefits depends on the environmental potential of the organic production system and on how effectively agricultural practices are applied. As far as environmental potential is concerned, various studies based on experimental research show that organic farming may play a key role in environmental conservation and natural resource management (Korsaeth and Eltun, 2000; Pimentel et al., 2005; Thomassen et al., 2008).
