I write with reference to Richard Fox's new device to allow tree-planting in Deserts and to the responses made so far. Firstly, Don Ewart said that many of the deserts in the world were human induced. From all I have heard about the destruction of Tropical Rain Forests/ other forests in the name of development, I would be tempted to agree. Many efforts have been made to re-plant/ plant in now dry areas. This gadget would seem to fit the bill especially as it does not abstract water from aquifiers, in time any trees established, could create their own microclimate and locally make the climate more suitable for growing crops. People need food so this would seem a good idea. Bob Keeland correctly pointed out that by abstracting from atmospheric moisture from one area would cause shortages down wind. I agree, and I'm not suggesting that people should go out and disturb the ecology of the deserts. I am suggesting that the device might help to re-claim those areas which we as humans have laid waste, spoil tips which are generally very dry. Trees could be established (after sorting out the problems caused by the chemistry-toxicity). Other possible uses could be to encourage plots in dry areas near villages so that people could be more self sufficient. In Britain, we are experiencing a heatwave which means hose-pipe bans. The air still contains much moisture which is mot being used. This could be utilised. I hope that this will inspire a little more active discussion.
