Rainwater harvesting is defined as a method for inducing, collecting, storing and conserving local surface runoff for agriculture in arid and semi-arid regions (Boers and Ben- Asher, 1982). … After infiltration has ceased, then follows the conservation of the stored soil water.
What is meant by water harvesting?
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.
How water harvesting is important in agriculture?
Rainwater harvesting has agricultural uses. It can be used for watering gardens in our homes and crop plants in agricultural fields. … And it can damage agricultural land areas. Rainwater harvesting can be used to divert heavy rainfall from reaching agricultural lands, thereby protecting crop plants from getting damaged.
What is water harvesting and its uses?
Harvesting rainwater allows the collection of large amounts of water and mitigates the effects of drought. Most rooftops provide the necessary platform for collecting water. Rainwater is mostly free from harmful chemicals, which makes it suitable for irrigation purposes.
What are the types of water harvesting?
Water harvesting involves relatively simple technology that can be used by both domestic and commercial properties to make a difference.
- Water Butts.
- Domestic Rainwater Harvesting.
- Commercial Rainwater Harvesting.
- Other Rainwater Harvesting Systems.
What is water harvesting introduction?
Water harvesting is the collection of runoff for productive purposes. Instead of runoff being left to cause erosion, it is harvested and utilized. In the semi-arid drought-prone areas where it is already practised, water harvesting is a directly productive form of soil and water conservation.
What are the advantages of water harvesting?
What are the advantages of rainwater harvesting?
- It is cost-effective.
- Conserves water.
- A source of water for landscape irrigation.
- It is a simple method and easy to practice.
- It reduces soil erosion and pollution of water bodies due to fertilizers and pesticides.
What is water harvesting and write its techniques?
A number of water harvesting techniques are based along contours including: contour ploughing; contour ridges; stone lines; grass strips and terraces. The technique used depends on the steepness of the slope, soil type, conditions, crops grown and other factors such as the availability of labour.
How is water harvesting done?
Rainwater harvesting systems capture rainwater by directing it from large surfaces (e.g. roofs) to an underground or over-ground holding tank. The harvested rainwater is filtered and then pumped directly to the appliances or to a header tank. Domestic or commercial applications include: Flushing toilets.
