Essay on Rain Water Harvesting
For an economy where agriculture is the backbone, nearly ”of the working population depends on
agricultural activities for their livelihood; monsoons seem to play a pivotal role here. The majority of India’s population depends on cereal and pulse production for sustenance.
Rainfall, therefore, significantly affects the agricultural production of the country by providing water for two main crop growing seasons- Kharib (summer) and Rabi (winter). Variations in the monsoon rainfall affect the total food grain yield of India and also the economy of the country, which is largely dependent on agriculture. The Asian monsoon climate is significantly dominated by Indian summer monsoon rainfall. Not just this, every year more than 80% of the annual rainfall is received over only the Indian land grid points. But, factors like climatic changes at national and global levels are leading to falling in water levels and this further gets burdened by overpopulation, causing the depletion of our water bodies.
The Value of Water Harvesting
The value of water is known to mankind from the time of Indus Valley and Mesopotamia civilization as the cities flourished around the river water. In places where the rainfall was erratic and less, like in Deccan and desert regions, various tanks were built to store water for dry spells. World 1 leritage sites like Rani ki Vav in Gujarat is a prime example of step wells which were built in the drier regions of India.
Steps are also underway to restore various tanks in Telangana region built by the Kakatiyas to make storing and managing of water efficient and also use the natural and ancient wisdom to restore the water balance in the ecosystem.

Liven for low-lying regions prone to Hoods due to over-taxed drainage systems; this process is the perfect solution.
Using rainwater harvesting systems, allows groundwater levels to recharge. This in turn helps in augmenting urban greenery. Besides all this, it also makes a good reservoir for irrigation purposes.

It employs low equipment cost as well. Besides this, it diminishes flood, erosion, and flow to stormwater drain by reducing peak stormwater runoff. As stored rainwater is free from pollutants as well as salts, minerals, and other natural and man-made contaminants, it leads to improved plant growth.
Combining Traditional Knowledge with Scientific Ways The temples of modern India the dams have created many opportunities for Hood control and irrigation but along the way the repercussion** have been devastating for people.
