Good day, Pc practitioners!

To the discussion on what Pc really is (concept, tool etc), in my view
of an agronomist working in tropical climate, where the processes are
speeded up, for example an organic matter decay of 50 years in Europe
occurs in 6 months in our savanna ecosystem, PC is a very well
developed model of natural energy input management, to achieve the
optimal biomass production of a site. PC uses waterbodies and different
kinds of plants.

Here in the Brazilian tropics we see that resident water conservation is
the most important life promoter. And this I get by soil conservation
practices using different kinds of plants, trying to accumulate the
biggest quantity and biodiversity of biomass. So I can reestablish an
useful complex hydrologic cycle and microclimatic buffering. The
forestry (agroforestry) is an important component of this system. PC
is a more complex agroforestry design, because of the detailed
calculations on energy management.

So I see PC as a superior agroforestry system adapted to the site
specific ecological conditions, paying attention to ecological principles.
Certainly the design will be site specific, depending on the local
energy and water input, and available soil properties (fertility,
drainage, depth etc.). What we need to keep in mind are the ecological
principles (they are unchangeable).

In relation to the spiritual events normally linked to Pc, the answer
is that people that try to use techniques adequate to attend ecological
principles, like Pc, are more linked to nature, to life! To Life! So, it
is not the opposite! Pc practitioners are nature friends, and therefore
more social worried.

With the best regards,

Odo Primavesi

(Note: To design the energy balance in a site, including different
management options (simulations) we need a specialist in this matter,
to establish a simulation program which will make it easier to design
site specific Pc systems. I am not such a gay. My matter is water and
soil conservation.)
