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 ...)

Peak Everything

Waking Up to the Century of Declines

By Richard Heinberg

The 20^th century saw unprecedented growth in population, energy consumption and food production. As the population shifted from rural to urban, the impact of humans on the environment increased dramatically.

The 21^st century ushered in an era of declines, in a number of crucial parameters:

Global oil, natural gas and coal extraction
Yearly grain harvests
Climate stability
Population
Economic growth
Fresh water
Minerals and ores, such as copper and platinum

To adapt to this profoundly different world, we must begin now to make radical changes to our attitudes, behaviors and expectations.

Peak Everything addresses many of the cultural, psychological and practical changes we will have to make as nature rapidly dictates our new limits. This latest book from Richard Heinberg, author of three of the most important books on Peak Oil, touches on the most important aspects of the human condition at this unique moment in time.

IPPY Award Gold 2008 - Current Events A combination of wry commentary and sober forecasting on subjects as diverse as farming and industrial design, this book tells how we might make the transition from The Age of Excess to the Era of Modesty with grace and satisfaction, while preserving the best of our collective achievements. A must-read for individuals, business leaders and policy makers who are serious about effecting real change.

About the Contributor(s)

Richard Heinberg is the author of nine books and is widely regarded as one of the world's most effective communicators of the urgent need to transition away from fossil fuels. With a wry, unflinching approach based on facts and realism, he exposes the tenuousness of our current way of life and offers a vision for a truly sustainable future.

Senior Fellow-in-Residence at Post Carbon Institute in California, Heinberg is best known as a leading educator on Peak Oil and its impacts. His expertise, publications and teachings also cover other critical issues including the current economic crisis, food and agriculture, community resilience, and global climate change.
