I came across a site that focuses on permaculture & havesting water
there are some great videos on the projects created.
ie: food forests that become no dig gardens :), gardens that defend themselves from pests and above all a healing enviroment on many levels. I am sure that you would find something there that interests you.
Do yourself a favour and be inspired by Geoff & Nadia Lawson who are making a difference to the world in practical ways that you yourself can impliment
have a great day
