[Digestion] Digestion Digest, Vol 6, Issue 13

Wed Feb 23 15:04:20 CST 2011

Dear Vianney,
It all depends where you are. In South Africa there are a rural million
householders who have livestock animals other than just chickens. From my
memory according to the Stats SA rural survey these householders have on
average of about 5 cattle, seven goats six sheep and three pigs, but this
depends from area to area depending on climate, grazing, water availability
etc.
It's a lot of energy and fertilizer.  
The South African National household biogas feasibility study conducted by
Agama Energy indicates that there are over 320000 householders that are
technically capable of participating in a biogas rollout as they have more
two or more cattle, access to water and no grid electricity.

Hi Vianney

I can't help with data but it strikes me that Africa is a big place - and
very diverse! There would be a lot of tribal people with just a handful of
beasts - hard to count - but if they are counted, they'd bring the average
number per owner down to a very small figure.

I would doubt the usefulness of any stats above national level - even if
they were accurate - so I am curious to know what you want the data for. I
guess I am finding it hard to think of any rational use for it!

G'day All,

Yesterday I had messages from 3 members who had been "unsubscribed" but
still wanted to be in the List. One admitted to receiving messages while on
holiday, with a holiday response, so I don't know if his mailbox filled up
or what.

If you are away for a while you should be able to set your listserver
membership to "nomail" to avoid some e-mails (it made my return from
holidays a bit easier as I had less messages to delete but could usually get
the jist of the previous e-mails from the "quotes" (that you should really
be stripped off before posting!). Go to
http://lists.bioenergylists.org/mailman/listinfo/digestion_lists.bioenergyli
sts.org and see what you can do for yourself!

Happy Digesting,

HOOROO
