What are Johad and Khadins?

Johad and Khadins

By gathering and storing precipitation, Johads, which are small clay check dams, promote groundwater recharge and percolation. There are more than 650 villages in Rajasthan’s Alwar district, which means the water requirement is high. Khadin is a system of land usage.

To collect surface runoff water for use in agriculture, a clever structure known as a Khadin was constructed. A long (100–300 m) earthen dam constructed across the lower hill slopes beneath gravelly uplands is the dominant feature of the area.

Facts about Johads and Khadins

Here are some facts about Johads and Khadins.

• With the help of sluices and spillways, extra water can be drained away.
• It is employed where valley plains and rocky catchments are close.
• The lower valley floor, encircled by an earthen “bund,” serves as a retention area for the catchment’s runoff.
• During the monsoon, water is stored in the Khadin.
• By the first week of November, it might already have been buried.
• Due to the ongoing deposition of fine sediment, the soil in the Khadin is incredibly fertile.
• A johad is a name for a rainwater collection tank.
• It continuously gathers and stores water.
• For drinking, both people and animals use it.
• These were constructed in low-water areas.
• There may not be enough rainfall in many areas of the state to make the water potable.
• Johads retain the rain that falls in July and August and throughout the year.

Summary:

What are Johad and Khadins?

While Khadin is a clever structure designed to collect surface runoff water for use in agriculture, Johad is a small clay check dam that collects and stores rainwater. Johads enhance groundwater recharge and percolation. Khadin is a very long around 100–300 m earthen dam constructed across lower hill slopes.
