Stopping the flow of water and storing it would be my biggest challenge. The wooded areas seem to slow the water down and have a lot of saplings that could be removed and other things to grow could be put there. I have some washout of my drives so every year I have to fix them. I understand the use of swales and terraces could help with growing stuff and keeping most of the water on my land. Hugelcultures would probably benefit me the most. It is a lot of work for just one person and I'm not the young man I once was.
