Definition Climate Farming

Climate farming uses agricultural means to keep carbon dioxide and other greenhouse gasses from escaping into the atmosphere. Like organic farming, climate farming maintains biodiversity and ecological balance on productive, argicultural land. But climate farmers like Hans-Peter Schmidt go a step further and covert leftover organic mass into biochar, a solid carbon compound that can improve soil quality. Biochar production also creates a kind of gas that can then be burned to help generate power. A climate farm could grow food, generate power, and help keep carbon out of the air.

Climatefarming – Pour une agriculture durable

von Hans-Peter Schmidt

Le climatefarming est souvent décrit comme une méthode agricole au moyen de laquelle du CO2 est prélevé de l’atmosphère et stocké de façon stable dans le sol sous forme de carbone. Ceci pourrait permettre de freiner le changement climatique. Mais le climatefarming, c’est également un concept écologique durable pour l’agriculture du future, qui produira aussi bien des denrées alimentaires que de l’énergie et de l’air propre, encouragera la biodiversité et protégera le paysage.

Au travers de leurs feuilles, les plantes prélèvent du dioxyde de carbone contenu dans l’air et le transforment à l’aide de la lumière, de substances minérales et de l’eau en molécules carboniques. Lorsque la plante meurt ou pourrit, ou si elle est mangée et digérée, les molécules longues de carbone sont de nouveau scindées. Ce processus libère de l’énergie et donc du carbone qui, composé à plus de 99% de CO2, s’évapore dans l’atmosphère. (en savoir plus ...)

Biochar recommended as fast-action strategie that may reduce the risk of abrupt climate change

Biochar should be accepted a climate change mitigation and adaptation technology for post-2012 treaty in Copenhagen. The International Biochar Initiative estimates that biochar production has the potential to provide 1 Gt carbon per year in climate mitigation by 2040, or 3.67 Gt CO2 per year, using only waste biomass The capture of atmospheric CO2 by plants to provide bio-energy followed by carbon capture and storage, combined with afforestation and biochar production, may have the potential to remove 100 ppm of CO2 from the atmosphere under the most optimistic scenarios( http://bit.ly/3NRThU).

Good by CCS Hello BCCS Bioenergie Carbon Capture and Sequestration

My fear is, that the new wonder tech promoted by big business will be CCS, and that all focus might be on a technology that will use up to 40% of produced energy for storing exhaust from coal into the ground. Not ready before 2020 said the industry this technology will cost billions. The easiest to reach the aim of 350 ppm is Bio sequestration. http://news.mongabay.com/bioenergy/2007/05/scie... Each year mankind produces Seven gigatons of CO2 by burning coal and oil. So when it succeeded in turning back the same quantity of biomass in coal - the world climate would be healed.Folowing Dr. Maria-Magdalena Titirici, Group Leader Max Planck Instituteof Colloids and Interfaces Colloid Chemistry Potsdam- it is relatively easy because the planet produces 120 cubic kilometers of dry biomass. Humanity is already throwing away 10 to 14 cubic kilometers as residual. Only biomass can be used for the creation of carbon-negative energy systems as it is known by gasification technologie. With bio sequestration we could clean up our emissions from the past 200 years.. All other renewables are carbon-neutral at best, meaning they can only reduce future CO2 emissions.But Large-scale industry is not interested in this procedure, because it changes the rules. The companies earn very well with current technologies and are not really interested in that change the rules of the competition. Therefor it is more then important that at Copenhagen climate talks bio sequestration is recognized as a greenhouse gas abatement technology. The idea has been submitted to the United Nations Framework Convention on Climate Change (UNFCCC) 5th Session of the Ad Hoc Working Group on Long-term Cooperative Action under the Convention (AWG-LCA 5) in Bonn, Germany, 29 March – 8 April 2009. And now we need both:Recognition of biochar carbon sink management as valid in the current and post-2012 LULUCF guidelinesInclusion of biochar in the CDM mechanism along with currently already included afforestation and reforestation 350.org should campaign for this ....
