I was just watching Australian Story on the ABC and saw this fellow Peter Andrews who helps farmers rehabilitate their land using local and cheap materials and methods. He is somewhat controversial and a little eccentric, which puts off a lot of farmers and politicians. However, he obviously uses the principles of containing and encouraging condensation WITHOUT machinery in rehabilitating eroded old creekbeds and dams. I must investigate his thoughts and methods- he could help the Murray. Here’s a link:
