[Iyrp-gcg] Biodiversity WG: Key Messages and Recommendations

[Barry Irving]

Rashmi and Chris;

Note this is a second attempt at this message.

Thank you for the diversity document.  It is evident there has been a great
deal of effort that went into this circular.  As I read it I can't help but
think there are a couple of areas that could be highlighted.  This may
indeed be due to my quick read.  If 20% of the earth's surface is
represented by commons, and 50%  is rangeland, then perhaps 30% of the
earth's surface and 60% of its rangeland are managed in some other fashion
than by the commons.  2 potential areas that spring to mind are public land
rangelands that are managed by single or near single pastoralists and
private land rangeland.  The private land rangeland could be a specific
bullet point because those areas are diversity hotspots, sometimes
occurring within a sea of converted land, and at the same time, as private
land, have even less protections provided (can be sold and converted to a
variety of other land uses).  Is there room to bring out the critical
biodiversity that is provided by public lands that are not managed as
commons and rangelands that are private land?

Support of biodiverse rangelands is also provided by sedentary pastoralists
who may use internal rotation on a reduced scale to mimic pre-history
migrations.  Sedentary pastoralists may also use moderate use practices and
integration with other forms of agriculture to allow sustainable use
practices (what is known as a mixed farmer, at least in North America).
Sedentary pastoralists may operate on public land held under disposition,
private land, or commonly a combination of both.  Often, an important
method of keeping biodiversity on areas managed by sedentary pastoralists
is to keep them on the land.  Because if they are not, the land tends to go
to other uses that often results in land conversion and a reduction in
biodiversity.  Is there room to highlight the value of biodiversity
maintenance that is provided by the managers of rangelands that are
sedentary?

Thanks for your consideration.
