Pollinator decline has no effect on global yields

Nature is reporting on a study that shows that “bees and many other insects may be in decline almost everywhere — but agriculture that depends on pollinators has been surprisingly unaffected at the global scale”. I have not seen the original paper, and I doubt that I am competent to assess it. But the report in Nature is intriguing. Using the FAO’s comprehensive dataset, Alexandra Klein and her colleagues observe no difference in yield patterns between crops pollinated by insects and other crops. There are other comparisons too, but the bottom line seems to be that local declines in yield with declining pollinators are not mirrored globally.

That’s no reason to relax, though.

Klein says her findings do not necessarily negate that idea that the world is in the throes of a pollination crisis. The data might hide how farmers have adapted to the problem, she suggests.

Nature goes on to suggest that a threshold-based catastrophe ((In the technical sense.)) may be around the corner.

Anyone care to comment on Klein’s paper? Or has Nature got it entirely right?

Honeybees no longer pampered on the Pampas

Ranching in South America tends to get a bad press because it is often associated with Amazonian deforestation, but of course there are vast swathes of the continent where it makes good environmental sense, as well as economic. ((For a discussion of the related question of the bad press that pastoralism gets, see this post in CABI’s blog, which coincidentally came out just a few hours after I posted this.)) The Pampas grasslands of Argentina are a case in point. The home of gaucho culture ((Which, incidentally, is not as homogeneous and predictable as one might think.)), the Pampas are undergoing drastic change. The soybean boom is not just having an effect on the livestock industry, but also, perhaps surprisingly, on honeymaking. Much smaller in value, no doubt, than either soybeans or livestock, but these are not times to pass up on diversification.

The value of pollination: euros 153 billion in 2005

INRA and CNRS French scientists and a UFZ German scientist found that the worldwide economic value of the pollination service provided by insect pollinators, bees mainly, was €153 billion in 2005 for the main crops that feed the world. This figure amounted to 9.5% of the total value of the world agricultural food production. The study also determined that pollinator disappearance would translate into a consumer surplus loss estimated between €190 to €310 billion.
