"I
live in North Thailand where smoke from burning corn and rice fields
blocks the sun a couple of months a year. Burning wheat straw smoke
closes Delhi every year, too.
Because
most of the farmers who burn are poor and small, collecting their crop
waste for central processing is uneconomical and their fields are too
small, too steep, too rocky to plow, even if they could afford a
tractor.
They
are so poor, however, that converting their crop waste to biochar makes
lots of sense. Establishing village-scale social enterprises to process
local biochar into value added products is also not only appealing to
farmers but a replicable way to solve the crop waste burning problem
where it starts - in small farmers' fields.
This
is the first of a five part series in which I make the case for a
small-scale biochar social enterprise business model for addressing the
problem. The remaining four will appear over the next few weeks.
I would welcome any comments, suggestions, corrections or criticisms."
