Permanent drought or Zero Emissions and drawdown of existing carbon

The drought is "permanent" or is it?
from Beyond Zero Emissions

The federal government has not taken climate change seriously, nor have the state Labor Governments, We're now in a position where we're moving towards "Permanent drought" according to Water Services Association of Australia executive director Ross Young.

"The need for moving as close to possible to a zero emissions common, is apparent and compelling, said Matthew Wright Campaigner with Beyond Zero Emissions

"A competent government, would work quickly to secure Kyoto's future and set goals that took the world as near as possible to zero emissions, and then using farming techniques such as Agri Char (aka Terra Preta -- see image above of Amazonian soil profile) like what the Mayan people used ten thousand years ago in the Amazon, we will be able to actively go to negative emissions and start to correct and normalise the climate securing the worlds food and water future" said Mr. Wright

The Bureau of Meteorology has admitted that their forecasts earlier this year for rain, were optimistic and based on the weather of the last 100 years. The Bureau is no longer able to do this, because we are moving into a new climate regime. This is shocking and the official line from the Bureau is "we can't predict when this drought will end" (Dr Coughlan)

With half of Australia's land in drought and farmers under financial and water stress, consumers in Australia's cities and towns are going to see big rises in food prices.

Given that we have 20 years of climate change effects built into the system that we haven't even seen yet, we hope that Australians will elect politicians who are going to seriously address these issues.

From Wikipedia:For a long time, the origins of the Amazonian dark earths were not immediately clear and several theories were considered. One idea was that they resulted from ashfall from volcanoes in the Andes, since they occur more frequently on the brows of higher terraces. Another theory considered formation as a result of sedimentation in Tertiary lakes or in recent ponds.

However, because of their elevated charcoal content and the common presence of pottery remains, it is now widely accepted that these soils are a product of indigenous soil management involving a labor intensive technique termed slash-and-char. The technique is differentiated from slash and burn by a lower temperature burn and in being a tool for soil improvement. Amending soil with low temperature charcoal produced from a mix of wood and leafy biomass (termed biochar) has been observed to increase the activity of arbuscular mycorrhizal fungi. It is theorized that terra preta self-propagates via this mechanism; a virtuous cycle established as the fungus spreads from the charcoal, fixing additional carbon and stabilizing the soil with glomalin, and increasing nutrient availability for nearby plants. The widespread peregrine earthworm Pontoscolex corethrurus (Oligochaeta: Glossoscolecidae), which thrives after burning of the rainforest, due to its tolerance of a low content of the soil in organic matter, has been shown to ingest pieces of charcoal and to mix them in a finely ground form with the mineral soil, pointing to its possible role in the formation of terra preta.

And a related comment from moi here:"David Murphy's book , Organic Growing With Worms has occupied me this week and the iconic figure of Peter Cundall writes in regard to it:

"This is an amazing, inspiring book..it should be on the bookshelf of every farmer, gardener, conservationist, scientist or anyone who comprehends the environmental dangers now threatening all life forms on earth."

Allowing for Cundall-speak -- and we all know how effusive Peter can be! -- the octogenarian is right! This is a very important book because it gives you a dirt and biota view of the planet and in so doing, offers a few key pointers as to solving not only soil degradation but the task of carbon sequestration and roll back. It challenges a lot of the rationale for --and presumptions that underpin -- broad acre farming.

And the star of the show is the humble earth worm.
