After I started the rock dam down in the back part of my property I began researching a bit more about the subject and came across this informative video about a similar type of project.

Sand dams, and even terracing have been used a lot in history to change the land and make it more productive. Many of these changes, if done correctly, can be made into something that is long lasting and something that benefits the surrounding land for a long time.

It's not just about saving water, it's also about making the land more productive. With more moisture in the soil people are able to grow different crops. Trees and other plants start to grow naturally and then those plants themselves influence the land as well by providing shade, shelter and food to other animals in the area.

If used responsibly and correctly this simple technology can influence a lot of lives and make a lot of people lives easier.
