And so on and so forth... Conventional agriculture causes increased greenhouse gas emissions, soil erosion, water pollution, and threatens human health. For some foodstuffs, there is an even bigger difference – for example, with organic Swedish winter wheat the difference is closer to 70 percent," says Wirsenius. We reviewed 34 comparative LCA studies of organic and conventional agricultural products to analyze whether this result is solely due to the usually lower yields in organic systems or also due to inaccurate modeling within LCA. Called a "carbon benefits index," this calculation measures the agricultural output of a given hectare of land in terms of volume of product and carbon dioxide emissions. With appropriate use of pesticides, less resources (such as fertilizers, land, irrigation) are wasted on pests and weeds – thus limiting the general effects of farming. Who paid for this study? Does anyone really think you can concoct any bullshit, attach the words "research" or "new study" and it becomes reality??? "For example, it is better for farm animal welfare. A more precise differentiation of farming systems is needed within LCA. I totally agree with matthew4506! We are exposed to a war between food industry and organic farming. The new study was published in the journal Nature. Finally, we recommend conducting consequential LCA – if possible – when using LCA for policy-making or strategic environmental planning to account for different functions of the analyzed farming systems. We cannot continue to farm intensively, the health and ecosystem costs outweigh the benefits. All this means is that from a carbon emission perspective, conventional animal farming may be better for the environment than organic. "Organic food does have several advantages compared with food produced by conventional methods," Wirsenius notes. The paper doesn't consider this option which skews the results. “If we use more land for food, we have less land for carbon sequestration. ", New research suggests organic farming has a greater impact on carbon emissions and the climate than conventional farming methods, The climate impact from Swedish wheat and peas produced organically, compared with conventional farming methods, Stefan Wirsenius/Chalmers University of Technology, Although direct emissions from organic agriculture are often lower – due to less use of fossil energy, among other things – the overall climate footprint is definitely greater than for conventional farmed foods, Yen Strandqvist/Chalmers University of Technology. Duh! But this new study, which had three major findings, shows that's not true. Copyright © 2020 Elsevier B.V. or its licensors or contributors. I would also question who funds such narrow minded research. Over 280,000 people receive our email newsletter. Does the study take into consideration the damage done to the ecosystem by fertiliser run off into streams and rivers. "Our results suggest that high-yield farming could be harnessed to meet the growing demand for food without destroying more of the natural world," says Andrew Balmford, lead author on this earlier study. The paper also assumed that organic farming would require the destruction of habitats that are already store high amounts of carbon.

In the future, more representative background data on organic farming systems (e.g.
