Organic food is generally more expensive than conventional food because organic production is more labor-intensive than large-scale industrial agriculture.
Supply and demand also play a role. Although demand for organic food has more than doubled over the past ten years, supply remains significantly lower.
Another factor is policy. Organic certification is costly and time-consuming, which further increases prices.
However, if we were to include the costs of soil erosion, water and air pollution, exposure to pesticides and antibiotics, deforestation, and species extinction, we would likely conclude that organic and permaculture-based food systems are more profitable overall. They have a more positive impact on the environment, animal welfare, and human health.
A good example is the long-term trial conducted by the Rodale Institute, which compared conventional and organic farming systems over several decades. The results showed that:
• yields in organic production, without synthetic fertilizers and pesticides, were not lower than in conventional systems
• in extreme weather conditions such as droughts, organic production achieved up to 30% higher yields
• organic cultivation increased soil thickness, microbial biomass, biodiversity, and biological activity
• organic practices improved water infiltration without the accumulation of toxic substances
