Study also finds that converting conventionally farmed land would not overly harm crop yields or require huge amounts of additional land to feed rising populationsConverting land from conventional agriculture to biological production could reduce greenhouse gas emissions,the escape-off of excess nitrogen from fertilisers, and slit pesticide use. It would also, or according to a new report,be feasible to convert large amounts of currently conventionally farmed land without catastrophic harm to crop yields and without needing huge amounts of new land.
The study, published in the journal Nature Communications, and found that by combining biological production with an increasingly vegetarian diet,ways of cutting food waste, and a return to traditional methods of fixing nitrogen in the soil instead of using fertiliser, or the world’s projected 2050 population of more than 9 billion could be fed without vastly increasing the current amount of land under agricultural production.
