Re: Permaculture in a Burr Oak Nutshell

Kathie,

Thank you for the feedback; I was hoping for comments. 

I think the question you raise about centrally managed
resources as being more efficient and thus less energy 
consumptive is quite valid.  

For example, what is more energy efficient, to pipe electricity 
to homes through centralized lines or to prop photovoltaic panels 
on every roof and shed in the neighborhood?  The total 
energy equation should include cost of manufacturing, materials, 
and transportation of all the pv-panels.  Of course, these
would have to be contrasted against the cost and energy
consumption of building a huge coal-fired electrical generating 
facility, high voltage lines, etc.  

Amory Lovins at The Rocky Mtn. Institute has been a
proponent of the soft energy path for decades.  RMI's 
publications are outstanding for their technical authority 
and analysis.  Thus, I would start there to arive at a
reasonable answer.  See RMI's web site at www.rmi.org, 
which contains many links to related energy sites including the 
National Renewable Energy Labs (NREL), Sandia Laboratories,
as well as appropriate technology sties.  

How does decentralized infrastructure lead to adoption of 
appropriate technology, energy conservation, and constructed 
wetlands? 

The premise here is that under a decentralized scenario,
individual human structures (homes, schools, and businesses) 
would produce energy on site (appropriate technology and
energy conservation), produce food on site (organic gardening 
et al), and handle waste water and sewage on site (constructed 
wetlands, greywater systems, humanure compost).  These on-site 
tasks follow the Principles of Permaculture, which are based
on ecological principles themselves.   

To be more specific and realistic, however, individual
human structures would attempt to accomplish these tasks as
much as possible, while perhaps coming up 30%-50% short in some
categories.  Thus, in reality communites will be a mixture of 
both centralized as well as decentralized systems.   

The main point from "permaculture in a (burr oak) nutshell"
is this:  to quickly understand permaculture, visualize 
integrated food production systems combined with ecologically 
designed built structures.   

The implication of on-site or decentralized infrastructure is 
that appropriate technology is the natural result, and A.T. is 
known to be closely associated with renewable energy and energy
conservation which are non-polluting technologies.  

Unlike sustainable agriculture which puts focus on the
farmer, the beauty of permaculture is that it takes into account 
everybody on the planet no matter where they live.  In fact,
the greatest benefit of permaculture will be felt in the cities.
Unless changes are made in urban settings, sustainable agriculture 
will have little impact on a global basis because the cities are 
black holes for resource consumption and workhorse generators of 
pollution.
