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 ...)

CABI to launch major push for improved soil health knowledge across Africa
Project will give farmers and policymakers in Sub-Saharan Africa knowledge they can use to improve soil fertility and boost farm productivity for millions
Press release, 6 December 2010

CABI, the non-profit science and development organization, has received funding from the Bill & Melinda Gates Foundation that will contribute to radical change in the understanding and use of Integrated Soil Fertility Management (ISFM) techniques in Sub-Saharan Africa, enabling smallholder farmers to grow more and better crops.

The four-year, $4.5 million project will work closely with scientists from research institutes in the region and Europe and in ongoing development initiatives, particularly the AGRA Soil Health Program. Using an open consortium approach, it will ensure that the wealth of research and new information available on the subject of ISFM is successfully brought together, communicated, and translated into action by everyone involved in farming systems development – from policymakers and university lecturers to extension workers, input suppliers and the farmers themselves.

“Soil fertility degradation has been described as the second most serious constraint to food security in Africa,” said Morris Akiri, Regional Director, CABI Africa. “After decades of reliance on biological approaches to soil fertility improvement, partly because fertilizer has not been easily available, agriculture experts now agree on the need to integrate fertilizer use with other aspects of soil fertility management. However, there is a desperate lack of knowledge, not only amongst farmers but amongst service-providers and decision-makers too. This project will address that knowledge gap.”
