In summary:
Part 1: Evidence of Organic Agriculture’s Better Impact on People and the Planet
Carbon & Greenhouse Gases (GHG):
Organic farming reduces GHG emissions by 43% per unit of land and 12% per unit of product compared to conventional farming (Chiriacò et al., 2022).
Global conversion to organic farming could cut farming emissions by 20%, mainly due to lower energy use and reduced nitrous oxide emissions (Scialabba et al., 2010).
In temperate climates, organically managed soils sequester 256 kg of carbon per hectare annually(Sanders & Heß, 2019).
Biodiversity:
Organic farming increases species richness by 34%, as shown in a global meta-analysis of 94 studies (Tuck et al., 2014).
Recent research highlights 95% more species on organic arable land, including 61% higher diversity in seed banks, 23-26% more flower-visiting insects, and 35% more farmland bird species (Sanders et al., 2022).
Soil Health:
Organic farming improves soil structure and fertility, reducing soil erosion by 22% (IFOAM, 2022).
Organic soils store up to 3.5 t/ha more soil organic carbon than conventionally managed soils, enhancing long-term fertility and carbon storage (IFOAM, 2022).
Water:
Organic soils demonstrate 15-20% greater water movement to groundwater levels, improving groundwater recharge (Müller et al., 2016).
They retain up to 100% more water than conventionally managed soils, supporting resilience to drought (Müller et al., 2016).
Organic practices reduce nitrate leaching by 20-39%, protecting water bodies from contamination (IFOAM, 2022).
Health Benefits:
Organic diets lower the risk of type 2 diabetes by 35% and cancer by 25%, with notable reductions in postmenopausal breast cancer (-33%), lymphoma (-76%), and non-Hodgkin lymphoma (-86%) (Kesse et al., 2020; Baudry et al., 2018).
Organic food contains higher levels of essential nutrients (e.g., 21% more iron, 29% more magnesium) and significantly fewer pesticide residues (94-100% pesticide-free) (Rembialkowska, 2007; Lairon, 2010).
Part 2: Why Major Positive Impacts of Organic Systems Are Underplayed Today
Misleading Metrics: Product-Level Analysis Favors Conventional Agriculture
Carbon and Land Footprint Bias:
Studies comparing GHG emissions often show varying results, depending on whether the analysis is per unit of product or per unit of land.
These inconsistencies arise because product-level metrics fail to account for broader ecosystem benefits, skewing comparisons against organic farming.
Broader Impacts Overlooked:
Product-level analyses ignore benefits at the hectare, farm, or landscape level, such as:
Biodiversity gains, ecosystem services, and reduced contamination of soil, water, and air.
Limitations of Product-Level Metrics
Diet and Consumption Patterns:
Evaluating sustainability solely at the product level does not reflect the impact of shifting diets (e.g., plant-based vs. meat-heavy diets).
Local Ecosystem and Community Impact:
Metrics fail to show the real influence of organic farming on local nature, ecosystems, and human health.
Natural Capital Protection:
Links between organic agriculture and the preservation of soil health, water quality, and biodiversity are poorly captured.
Recommendation:
Assess impacts beyond product-level indicators:
Use hectare-based or landscape-level metrics.
Measure impacts at the farm level or within entire food systems.
Integrate ecosystem quality and local biodiversity into sustainability assessments.
Unmeasured or Misrepresented Impacts
Soil and Land Degradation:
Soil health, a critical factor in sustainable farming, is rarely considered.
Pesticides and Nitrogen Fluxes:
Life Cycle Assessment (LCA) poorly models the impacts of pesticides and nitrogen fluxes, underestimating their harm.
Provision of Ecosystem Services:
Benefits like carbon sequestration, pollination, and habitat creation are rarely quantified in comparisons.
Recommendations:
Move beyond common metrics like GHG emissions and land use.
Incorporate soil quality, biodiversity, and pesticide effects in sustainability assessments.
Apply precautionary principles when current models fail to fully account for organic farming’s benefits.
Part 3: What needs to change in major reporting frameworks to impartially reflect the environmental benefits of organic agriculture
Relevance of Organic Farming for CSRD
Organic practices reduce negative environmental impacts (e.g., water retention, biodiversity gains) and align with CSRD’s sustainability focus.
Area-based metrics provide a holistic view of environmental impacts, but the lack of sector-specific standards complicates comparisons.
Increased land use by organic farming raises concerns about deforestation, emphasizing the need to frame organic as a proactive solution to risks.
Scope 1, 2, and 3 Emissions Reporting:
Comprehensive emissions reporting allows organic systems to highlight reduced emissions from lower synthetic input reliance and nutrient recycling.
Challenges:
Insufficient data on biodiversity, nitrogen emissions, and animal welfare limits the ability to validate organic farming’s broader impacts.
Recommendations:
Fund research to standardize metrics for biodiversity, nitrogen, and soil health.
Promote organic farming as a risk mitigation and sustainability strategy within CSRD disclosures.
