AFRICAN TREE NURSERIES

TREE NURSERIES for CARBON EMISSIONS

More than 92 percent of all nurseries catering to villages are still located at regional and district levels. As a result, seedlings have to be transported long distances, sometimes even beyond 50 km. The inadequacy of transport is one of the major setbacks in tree-planting, in terms of both availability and cost. All efforts must be made to decentralize Africa tree nurseries as much as conditions allow.

To bridge this energy supply-demand gap, a massive amount of tree-planting is needed. The natural forest is shrinking very fast, and most alternative energy sources have had no significant impact so far.

One of the main reasons tree-planting is failing among some African communities is that they are often given species only for firewood, like eucalyptus. 

 Weak village leadership contributes directly to delays over deciding whether to plant trees or not; and then, even if trees are planted, it can retard or neglect maintenance.

THE NEXT STEP: ORCHARDS AND BIOCHAR

Each woman farmer and their family will begin the task of preparing to plant 300 fruit and nut trees on their leased 1.5 acre farms, Every tree will need a 2- 3 feet diameter excavation, where a biochar earth mound will be built of branches.

EARTH MOUND KILN

biochar mound

The earth mound kiln is built in the following manner:

The bottom of the base is covered with logs forming a grate or crib on which the wood is piled vertically. The grate forms a free space between the bottom and the wood charge through which the air necessary for the carbonization process passes. The piled wood is covered with leaves and grass and then earth about 20 cm (8”) thick.

The pile has an outside stack made of steel drums, which is connected to the pile through a flue cut into the ground, running under the pile and covered with round logs. The pile has a number of air vents located around the circular base.

The carbonization process is started by introducing a torch into the firing flue opposite the stack. This type of pile is reported to be easy to operate to produce good charcoal quality with a yield of 55% charcoal to wood by volume. The pile’s volume varies from 100 to 250 m³ of wood. The whole cycle takes 24 days; four days for charging, six days for carbonization, ten days for cooling and four days for discharge.

 Carbon Emission to be Solved

The world leaders must find a way to absorb carbon dioxide emissions that is in our atmosphere now. Trees and soils are the only way to absorb the present glut of CO2 in your world. Continue reading AFRICAN TREE NURSERIES

CARBON TAX: Not Enough 2

Carbon Tax Failure: NOT Enough

There is a failure of the press to cover urgency of carbon tax. Carbon should not flow unpriced into the atmosphere, any more than you should be allowed to toss your garbage in the street. It makes no sense that the fossil fuel industry is allowed to put out their waste for free, using the atmosphere as an open sewer.

Nearly all of those decisions share a common, crucial element: they are shaped, by the relative prices of available energy choices. The only way to get enough change is to send a price signal so that everyone from investors to car buyers will change their behavior automatically:  a kind of perpetual motion machine. 

A straightforward plan is simply to tax carbon directly. Canada has introduced the gradual approach of a $10/ton of carbon emissions to finally get the ball rolling, while some of the provinces have elected to increase this tax to $30/ton.  In the meantime, Exxon has been planning for $50 a ton to make sure it won’t put a crimp in their business.  

Yes, carbon tax is inevitable but one thing stands in the way: PRICE POINT.  If we want to move the needle, we have to move the market. We need a top down message. A steadily rising tax on fossil fuels will send a strong price signal. A proposed carbon tax pending in the New York state legislature (A.B. 8372:  proposes to increase the tax gradually from $35 to $185 per ton.) 

Is that the only thing that needs to be done?
