Harvesting Rain Water

Water is the most important resource for any kind of food production and living. Though most of the planet is full of water, we can't use it. Every year we dig deeper to find water to drink or irrigate. The other alternative is to build large dams and block flow of river.

We can use the small swales and dams to harvest the rain water. The combination of swales and dams can also be used for passive irrigation. In this process we slow down water flow. This enables the land to absorve more water. Depending upon the land size we can build a small or large dam or swale system. So lets see the video...
