Chapter Three - Environmental Impact of Organic Agriculture 1. Under OA management, a higher CH4 uptake of 3.2 kg CO2 eq. Biodiversity. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Environmental Impact of Organic Agriculture. Organic farmers are both custodians and users of biodiversity at all levels. ha−1 y−1 may be observed for arable soils. Supporting Animal Health and Welfare. Specifically, by the adoption of OA practices 1.65 Mg CO2 ha−1 y−1 may be sequestered in the top 20-cm layer. Further, N2O emissions from soils managed by OA may be 492 kg CO2 eq. Some scientists posit that as long as agriculture remains focused primarily on profit, organic farming will only have a minimal impact on environmental protection and reducing climate change. Specifically, yields under OA are about 19% lower and the attendant lower soil carbon (C) inputs together with tillage for weed control contributes to lower profile soil organic carbon (SOC) stocks under OA. Organic agriculture encourages the use of sustainable farming methods and discourages the use of toxic chemicals; as a result, it can: Reduce air, water, and soil pollution Save water and energy Build healthy nutrient-rich soil However, scientific evidence for better environmental impact is scanty. The soil, air, and water quality may also be enhanced by OA whereas effects on biodiversity are mixed. Specifically, OA is perceived by many as having less negative effects on the environment than conventional agriculture because applications of soluble mineral fertilizers, and synthetic herbicides and pesticides are prohibited. Consumer demand for organic products will continue to grow driven by food safety concerns and increasing affluence. He said while the farmers in this region express concerns about the environmental harms and impacts of the agrochemicals used in conventional farming, the reason th… Insects, birds, fish and all sorts of other critters experience … Michel Cavigelli, a soil scientist with the U.S. Department of Agriculture, works with farmers in the mid-Atlantic who are seeking to convert to organic farming. Current State of Organic Agriculture. Less well known are the effects on soil inorganic carbon (SIC) stocks. There are, however, some contexts where organic agriculture may be considered appropriate.

Organic agriculture (OA) is practiced on 1% of the global agricultural land area and its importance continues to grow. Otherwise, soils managed by OA may emit less carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). Despite strong public perception of organic agriculture producing better environmental outcomes, we show that conventional agriculture often performs better on environmental measures including land use, greenhouse gas emissions, and pollution of water bodies. Thus, there is an urgent need to strengthen the database on environmental impacts of OA by establishing and studying long-term field experiments in all major biomes and principal soils. Introduction. ha−1 y−1 lower than those from conventionally managed soils. Due to lower yields, however, natural ecosystems may be increasingly converted to agroecosystems to meet the demand with less well-known consequences for the environment.

In December 2018, researchers from Chalmers University of Technology published a study in the journal Nature that found that organic peas farmed in Sweden have a bigger climate impact (50 percent higher emissions) as compared to peas that were grown … Of late, the conversation about organic farming has shifted from its lack of chemicals to its impact on greenhouse gas emissions.

Nonetheless, scientific interest in OA is less than a century old, and there is significant potential to lessen its environmental impacts while methods derived from OA can contribute to sustainable intensification of agricultural systems.
