I'm in a part of Africa that has a five month rainy season. Drought is an issue for most of the year. I've become intrigued with the idea of improving the availability of groundwater to trees and plants as a year-round irrigation technique. I'd like some information on how I can raise the water table on 2 acres of fairly flat land (the property is actually bigger than this but the rest is forest I want to leave untouched). It would be fantastic if you could point me to resources that deal with this topic in depth. How can you advise me? What are some of your tips?
