In a drying landscape one thing we can do to halt desertification is to restore small water cycles. What does that mean? It means keeping the water that does fall or comes down through irrigation and streams in local circulation. There are many ways to do this through the way we graze animals, to keeping our ditch water above ground, planting and caring for trees, and restoring soil health. The simple global principal at work here is that in the biosphere, water follows carbon. Where there is more carbon there will be more water.
