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 ...)

Tanzania, which once prided in being among the greenest countries on the continent faces major threats of looming desertification brought about by major acts of deforestation. Apparently, despite its reported massive gas reserves, Tanzania still relies heavily on charcoal as a major source of fuel for the majority of the country�s nearly 45 million residents�

Since it takes wood to produce charcoal, Tanzania suffers an annual loss of 400,000 hectares of forests with the main culprit behind this depletion of its major natural resources being the domestic fuel demand.

All urban centres’ residents use charcoal as the main domestic source of fuel while their rural counterparts still relie on firewood but both of these have to do with axes and chainsaw chopping down natural forests.

It is estimated that Tanzania’s urban centers consume over one million tons of charcoal every year with nearly 500,000 tons being burned annually, and half of it consumed in the country’s commercial capital of Dar es Salaam.

High costs of alternative and much cleaner fuel sources such as gas and electricity continue to drive the reliance on wood and charcoal for the 80 percent of the population.

State organs and Non-Governmental Organizations have tried various strategies to address the problem, but little has been achieved in curbing deforestation. This has been partly contributed by poor technology used in burning charcoal. Other factors include limited alternative sources of energy, as well as weak law enforcement mechanisms ....
