               1.  Sub Topic- Rainwater Harvesting


                   Rainwater Harvesting
                        •  The system of collecting and storing rainwater.
                        •  Prevalent and useful in water deficient regions such as Rajasthan and dry parts of
                           Gujarat.
                        •  Uses
                                  For recharging ground water
                                  For domestic usage
                                  For irrigating crops
                        •  Roof-Top Rainwater Harvesting
                                  Rainwater is collected in underground tanks connected to the rooftop
                                  through pipes.
                                  Rain falling on rooftops travels down the pipes to the tanks and is stored for future
                                  usage.
                                  Also used for recharging hand pumps and tube wells.
                                  Most common is the desert districts of Rajasthan.
                   Bamboo Drip Irrigation System
                        •  Practised in Meghalaya.
                        •  A 200-year old system.
                        •  Water from the streams is tapped using bamboo pipes and used for irrigating the roots
                           of plants.
                        •  Long bamboo pipes are connected with each other to form a chain from the stream to the
                           crops.

                        •  Water flows through the pipes and drops directly at the site of the plant.
