Micheal Palace, May, 2011

Micheal Palace has been kind enough to share the attached poster with some of his initial work detecting Amazonian dark earths (called ABE in the poster) using satellite images from NASA's Hyperion spectrum scans of the Amazon region.

The team of scientists working on the technology have been correlating archeological evidence of the Dark Earths (ABE) and the Hyperion scans of the same areas to see if they can find a way to reliably use the scans to detect other areas of Amazonian Dark Earths. Ultimately, they'd like to use the Hyperion data to find the extent of the dark earths in the Amazon basin, and be able to provide archeologist with the statistical likelihood that there are actually ancient dark earths in the areas indicated by the scans.

University of New Hampshire has a nice write up of Micheal's work:

Nice video, and a trip up the Amazon to see Terra Preta, Black Earth Soils.
15 minutes, and nicely captioned.

After the conference, about 50 participants flew to Manaus and boarded the well-appointed riverboat, Helios Gabriel on Thursday evening September 16th, 2010. There were plenty of opportunities to carry on discussions begun at the conference.

The objective of the first day was to visit small farmers growing crops on Terra Preta sites at the Costa Naranjal, the

Bio-char Projects

Currently (January 2007) we conduct experiments to evaluate the effects of bio-char on nutrient adsorption, nutrient leaching, water percolation, soil water availability and carbon cycling as well as the stability and mobility of bio-char itself with research in our Ithaca lab, in Colombia, Brazil, Zambia and Kenya.

Green Charcoal by Pronatura International, France

Two billion people around the world use wood for household energy needs. This contributes significantly to the world's deforestation activities as well as increasing the risk of droughts and desertification. In an attempt to reduce deforestation, Pro-Natura has developed Green-Charcoal.

This technological innovation, using agricultural residues and unused biomass, produces an environmentally friendly and economically competitive alternative to wood and charcoal. It has been awarded the 1st Prize 2002 of the ALTRAN Foundation for technological innovation.

Carbon sequestration is another means of mitigating glbal warming. Reforestation and agroforestry practices allow the excess of carbon dioxide in the atmosphere to be stored in trees and in soil (in the form of organic matter). The consequent revitalization of the soil also improves agricultural productivity. In this field Pro-Natura collaborates with Eco-Carbone.

Pro-Natura International has developed a continuous process of pyrolysis of vegetable waste (agricultural residues, renewable wild-grown biomass) transforming them into green charcoal. This domestic fuel performs the same as
charcoal made from wood, at half the cost. It represents a freeing up from the constraints of scarcity, distance and cost of available fuels in Africa.

The machinery required for the process is of relatively modest scale and functions on practically no outside energy and no emission of toxic fumes, it only takes 8 kW of electric power. When run by two persons, it can produce
more than 4 tonnes of green charcoal a day.
