Rain Water Harvesting as a method of utilizing rainwater for domestic and agricultural use is already widely used throughout the world. It is a method that has been used since ancient times and is increasingly being accepted as a practical method of providing potable water in development projects throughout the world. It has wide application also in urban and rural areas where the reliability and quality of piped water is increasingly being questioned. Despite these facts the percentage of households using rainwater harvesting is too much. Rainwater harvesting is defined as the process of collecting and concentrating runoff water from a runoff area into a run-on area, where the collected water is both directly applied to the cropping area and stored in the soil profile for immediate use by the crop. It is stored in an on-farm water reservoir for future productive uses like for domestic use, livestock watering, and aquaculture irrigation.

Cheap and best method

Rainwater harvesting for crop production is a promising and normally appropriate way of upgrading rain fed agriculture in the semi-arid tropics. It is especially interesting given the fact that farmers experience crop yield reductions more often, due to poor rainfall distribution rather than inadequate total rainfall. Irregular and unreliable rains result in frequent dry spells that often result in serious reductions of crop yields. Farmers know this and adapt their investments in, for fertilization, weeding and pest management accordingly. High risk for water stress leads to low incentives for investments to the farmers. This means that water harvesting can function as an entry point for farming systems modernization in the semi-arid areas. There are many books and institutions to help farmer to teach this process of harvesting. This organization shows the potential of applying rainwater harvesting on smallholder farms in semi-arid areas. It gives practical tips on how rainwater harvesting can form an integrated part of district development efforts. This type of book provides a practical guideline in the planning steps required to incorporate rainwater harvesting in development plans, and shows how to implement them in the farmer's context. To use rain water in harvesting is the best cheap and the most useful way to save and conserve drinking water.
