Mapping the conflict between farming and biodiversity statuses PNASNews
One of the main problems, the study found, results when food production overlaps with areas that have been identified as having the highest conservation priority. The findings are published in the journal"Food production remains the main cause of biodiversity loss," said Keiichiro Kanemoto, an associate professor at the Research Institute for Humanity and Nature in Kyoto, Japan and one of the paper's senior authors.
The researchers found that about one-third of all farming occurs in areas that were considered highest conservation priority. One pattern that emerged was that some staple commodities, such as beef, rice, and soybeans, tended to be produced in high conservation priority areas. At the same time, other substitutes, such as barley and wheat, were predominantly sourced from lower risk areas.
The study also illustrated how different nations can have sharply different biodiversity food footprints. The United States, EU, China, and Japan all depend heavily on imports to satisfy their demand for beef and dairy. In Japan, more than one-quarter of the beef and dairy consumed in that country comes from high conservation priority areas. For the other regions, that number is closer to just ten percent.
