Explanation: To increase productivity while conserving water (more for less), the farmers should adopt micro irrigation methods. In drip irrigation for example, perforated pipes are placed either above or slightly below ground and drip water on the roots and stems of plants, directing water more precisely to crops that need it. An efficient drip irrigation system reduces consumption of fertiliser (through fertigation) and water lost to evaporation, and higher yields than traditional flood irrigation.
