Carbon-Circulating Agriculture |
Carbon-Circulating Agriculture (carbon cycle by agriculture)
is one of the ways for natural farming through carbon cycle to achieve
same level of carbon fixation to forests with keeping same (or more)
productivity with ordinary agriculture method. It is distinguished
from ordinary agriculture by effective utilization of microorganism
(fungus and bacteria) in the soil.

In ordinary agriculture, chemical fertilizer
is used as manure, and after the harvest, the residua (stems or leaves)
will be dumped out, mostly burned out. It means, even some carbon
fixation occurred, most of them would be emit back as CO2.
On the other hand, in Carbon-Circulating Agriculture, such residua
will be decomposed by microorganism and become natural manure, as
in forests. So, the carbon fixation is maximized, will reach the natural
levels of forest.
We all know trees in the forest can be grown up even nobody gives
them fertilizer. Leaves from trees fall down to the land, then microorganism
decompose it and make the soil fertile. So, trees will grow up well
on the fertile soil, and leaves will fall down…such natural circulating
activity is the key factor of the forest.
In Carbon-Circulating Agriculture, we set up this carbon cycle activity
of the forest on the agriculture field. For speedy circulation, residua
and other natural carbon resources is put into a form which microorganism
can decompose easily, so we can attain more productivity than ordinary
agriculture method. And, as there is no usage of agrochemical and
chemical fertilizer, we will harvest high quality vegetables, and
be categorized as organic vegetables*.
*In most country, crops that can display as "Organic" are certified by approved certification organizations only.

The Effect |
According to the IPCC's Fourth
Assessment Report (AR4), global greenhouse gases emissions due
to human activities have grown since pre-industrial times, with
an increase of 70% between 1970 and 2004. Food and Agriculture
Organization of the United Nations (FAO) indicated on its Global
Forest Resource Assessment 2000 (GFRA 2000), global
forest area in 2000 was 13,064 million hectare, decreased 9.4% from
1990. To avoid global warming, it is important to secure photosynthesis
and carbon fixation. But two statistics above show the trend is running
counter to this issue.
To solve this problem, Carbon-Circulating Agriculture
is one of the critical answers. By maintaining productivity and securing
photosynthesis and carbon fixation, the vegetable field will be an
equivalent to forest in the view of carbon fixation.
As of 2001, we have 13,067 million hectares of farm land
in all over the world, almost same size of the global forest area.
Can you imagine what will happen, if we could make all this farm land
adopt the Carbon-Circulating Agriculture? |
