Thank you very much for your info of the very
interesting man in the very dry land. I am in
Thailand, Southeast Asia and having my own land close
to a river. We have just passed the worst flooding
ever so I have different problem from Mr.Phiri but in
summer here it is also very very hot. I am trying to
study ways to grow trees in this area also and will
plant trees, vegetable for in the form of sustainable
agriculture. The more I read of those poeple in the
"impoooible to do agriculture area" the more I feel
how lazy I am in not using the good earth I have.
Thank you again for your info.
