Low-yield organic farming, rewilding & so-called 'nature friendly farming' measures may accelerate global biodiversity loss. Why isn’t the Govt listening, ask two leading UK researchers.

Current conservation policies risk accelerating biodiversity loss

Tästä vastakkainasettelusta kiinni ja sen kimppuun (Jon Entine):

Disaster interrupted: Which farming system better preserves insect populations: Organic or conventional?

Torjunta-aineet, mutta  myös  tämä näkökulma:

Of course, the positive association between agriculture and insect population increases applies to existing fields, not forest or natural grassland cleared for cultivation. As van Klink has pointed out in interviews, the conversion of land to accommodate more farming would also destroy habitat.

But that is exactly the point if sustainability is the key: using technology to boost yields on existing cropland—growing more food on less land—is the most important action we can take to protect habitat and biodiversity.

And that’s what’s been happening. In a 2013 paper titled “Peak Farmland and the Prospect for Land Sparing,” three scholars at Rockefeller University calculated that global increases in crop yields as the result of advanced technologies, including genetic engineering, meant it took about one-third the amount of land in 2010 to grow the same amount of food as in 1961.
