It means capturing rain where it falls or capturing the run off in your own village or town. And taking measures to keep that water clean by not allowing polluting activities to take place in the catchment.
Therefore, water harvesting can be undertaken through a variety of ways
Capturing runoff from rooftops
Capturing runoff from local catchments
Capturing seasonal floodwaters from local streams
Conserving water through watershed management
These techniques can serve the following the following purposes:
Provide drinking water
Provide irrigation water
Increase groundwater recharge
Reduce stormwater discharges, urban floods and overloading of sewage treatment plants
Reduce seawater ingress in coastal areas.
In general, water harvesting is the activity of direct collection of rainwater. The rainwater collected can be stored for direct use or can be recharged into the groundwater. Rain is the first form of water that we know in the hydrological cycle, hence is a primary source of water for us. Rivers, lakes and groundwater are all secondary sources of water. In present times, we depend entirely on such secondary sources of water. In the process, it is forgotten that rain is the ultimate source that feeds all these secondary sources and remain ignorant of its value. Water harvesting means to understand the value of rain, and to make optimum use of the rainwater at the place where it falls.

Question => Define results of water harvesting system
⚡⚡Rainwater harvesting is defined by Wikipedia as “the accumulation and deposition of rainwater for reuse on-site, rather than allowing it to run off.” While this definition is basic, the practice of rainwater harvesting is greatly varied from where the rainwater is collected from to how the rainwater is ultimately used.⚡⚡
⚡⚡The harvesting of rainwater simply involves the collection of water from surfaces on which rain falls, and subsequently storing this water for later use. Normally water is collected from the roofs of buildings and stored in rainwater tanks. This is very common in rural Australia.⚡⚡
⚡⚡Definition. The term 'water harvesting' generally refers to the collection of rainstorm-generated runoff from a particular area (a catchment) in order to provide water for human, animal, or crop use.⚡⚡
⚡⚡What are the benefits of rainwater harvesting? It will reduce water bills, provide an alternative supply during water restrictions and help maintain a green, healthy garden. In fact, depending upon tank size and climate, rainwater harvesting can reduce mains water use by 100%.⚡⚡
⚡⚡The importance of rainwater harvesting lies in the fact that it can be stored for future use. Just as it can be used directly so also the stored water can be utilized to revitalize the ground level water and improve its quality. ... Harvesting rainwater checks surface run off of water and reduces soil erosion.⚡⚡
