Hey Alpha. Thanks for your articles. I am wondering, what would be the effects of rainwater harvest works through vegetation and small earthworks on a small scale farm of 1hectar?

Is it possible for such a place to dampen local effects of lowering groundwater?

A small farm of a friend deals with less water in the well. Knowing that Geoff Lawton created moist soil in Palestine where it only rains 4 weeks a year, I am wondering if the effort of using rainwater harvest in a region where larger farms keep lowering water levels of aquifers does even make a difference for the small farm locally?

Maybe you can answer with an article, as this probably interest many of your readers.

Thanks you!

Hi Robert, if larger farms are draining the aquifers, I think it still useful to recharge aquifers on a small farm. 1 hectare can still recharge a substantial amount. But its also important to bring the issue of groundwater depletion to the regional governance. There can be education done, and perhaps over time, regulations can be put in, to stop the draining of the aquifers.

Hi Robert, on a small farm you can definitely increase soil moisture and also groundwater levels. Less likely to have a large impact on an aquifer, which is deeper water, and often ancient water.

What happens to water vapor when warm air columns or other transport phenomena carry the H20 molecules into the statosphere or above? Doesn't global warming imply more water vapor in the atmosphere? If so does that imply more water loss in the upper reaches of the atmosphere? Is it a negligible loss or something we should get worried about?

Global warming does imply the atmosphere can hold more water before it rains out. It means we thus get more droughts, and also when it does rain, we may get larger storms. ... Water vapor does go into the stratosphere, I am not sure if that is a significant issue or not...
