Rainwater harvesting is nothing but collecting rainwater when it is available (monsoons) and using it when there is water scarcity (summers or droughts) for human use. With the rapid changes in climate, global temperature and population, the availability of potable water are very scarce across the globe. The gradual decrease of potable water is a serious concern as it not only reduces freshwater but also causes an imbalance in the salinity of the coastal area. The only way to sustain this problem is to increase freshwater availability. And we can achieve this through rain water harvesting. Thus it is crucial to create awareness about the rainwater harvesting importance and its benefits.
So here are a few insights into why Rainwater harvesting is important.
1. Permanent solution for the water crisis
the collection of rainwater or Rainwater harvesting is a permanent solution to the water crisis we are facing globally. This is a feasible solution for you in the areas which acquire sufficient rain but don’t have sufficient groundwater or if the water resource is not sufficient. This is applicable mainly in hilly areas and the harvested water can be utilized by humans, animals, and farming.
2. Fractions of water available are fit for human consumption
Although 2/3rd of our earth’s surface is water, all the water is not suitable for human use or agriculture. Rainfall is unpredictable and there is always a constant shortage of water for agriculture-dependent countries or drought-prone regions.
3. Poor monsoon.
When a region has poor monsoon the result is low agricultural yield and food shortage. Farmers and Animals are majorly affected due to water scarcity. The farming is affected as the irrigation facility is disrupted. Therefore it is crucial to educate the farmers about the rainwater harvesting importance and its benefits.
4. Polluted water and water-borne diseases
When water is scarce, people are forced to use polluted water for consumption. This results in many water-borne diseases and higher infant mortality.
5. Alternative water source
Harvested rainwater can be an alternate source for the main supply of water. The water harvested is not limited for a single-family, but can be used by an entire community. If rainwater is harvested systematically it can be used for irrigation using minimum technology. Thus it becomes cost-effective and a simple method to prevent crops from drying.
The current situation of water scarcity is visible worldwide and it is time to spread more awareness about minimal use of water and its conservation. Farmers and drought-prone areas need to be aware of rainwater harvesting importance. It shouldn’t stop with awareness rather the government and other local bodies need to support them with the feasible models to harvest rainwater during the monsoons.
