I disagree. Just following your source to its conclusion, I think it’s safe to say OA (organic agriculture) is better all around:
7.1 Pros • Lower emissions of CO 2 , N 2 O, and CH4 • Enhanced soil and water quality • Lower energy use per land area • Higher energy efficiency per land area 7.2 Cons • Lower soil profile SOC stocks [i.e. how much carbon is in the soil] • Lower crop yields • Higher land requirement • Lower energy production per land area
Your conclusion that we’d have to clear more land for agriculture use if we all switched to OA seems flawed; e.g. here in Germany we use about 60% of agricultural land to raise livestock feed like corn etc (landwirtschaft.de/…/was-waechst-auf-deutschlands-…). Seems to me like eating less meat and growing idk lentils or beans would not immediately lead to food insecurity.
This is also what the FAO says: yes, OA leads to yield reduction when compared to conventional methods, but not to food scarcity and instead to healthier ecosystems (www.fao.org/organicag/oa-faq/oa-faq6/en/).
