What are Johads and Khadins ?

What are Johads and Khadins

Khadins and Johads are age-old systems of rainwater harvesting primarily employed in India. These are some strategies used in ancient india (mostly) to save rainwater by making some structures on the ground so that water will be stored in them and can be utilized when there is an urgent need for water or water scarcity. Johads are usually constructed in low-lying areas where water can accumulate naturally. whereas Khadins, on the other hand, are rainwater harvesting structures built in Gujarat.

Johads and Khadins are the following:

1. Johads

Johads are small earthen check dams which capture and conserve rainwater, improving percolation (It is the process by which water moves downward through the soil under gravitational forces.) and groundwater recharge. These are spread across more than 650 villages in Alwar district, Rajasthan.

2. Khadin

Khadin is an innovative construction designed to harvest surface runoff water for agriculture. Its main feature is (100-300 m) long earthen dam built across the lower hill slopes lying below gravelly uplands. Channels and spillways allow excess water to drain off.

Attributes of Khadins

Khadins are traditional barriers made of soil, usually constructed along the contours of agricultural fields. Their key features encompass:

1. Contour-Oriented Layout: Khadins are meticulously built along the natural shape of the land. This facilitates the efficient collection of rainwater runoff while curbing soil erosion.
2. Gravity-Driven Movement: Rainwater accumulated by Khadins gently flows along the contour lines, permitting gradual percolation into the ground. This process replenishes groundwater reservoirs.
3. Catchment Territory: Khadins are often linked to a catchment area like a small hill or ridge, channeling rainwater toward the embankment.
4. Inlet and Outlet Structures: Equipped with inlet and outlet mechanisms, Khadins regulate water flow, preventing overflow and ensuring uniform distribution across the field.

Attributes of Johads

Johads, referred to as village ponds or tankas, are another form of traditional rainwater harvesting practiced in India. Their salient attributes encompass:

1. Depression-Based Configuration: Johads take the form of shallow, saucer-like excavations or minor reservoirs carved into the ground. They are strategically placed at lower elevations to amass rainwater runoff.
2. Wide Catchment Scope: Johads are intended to capture rainwater from extensive catchment areas, often spanning multiple villages or agricultural tracts.
3. Versatile Applications: In addition to catering to agricultural needs, Johads serve as water sources for drinking, livestock, and domestic consumption. Larger Johads sometimes also support fish cultivation.
4. Community Ownership: Typically, Johads are collectively managed by local communities, fostering a sense of shared responsibility.

Examples of Khadins and Johads

1. Khadins

Rajsamand Lake, Rajasthan, India

The Rajsamand Lake, built during the 17th century, stands as an exemplary traditional Khadin system. Spanning approximately 45 kilometers, it was ingeniously designed to collect rainwater from the Aravalli hills. Apart from serving irrigation purposes, the lake holds cultural significance and provides potable water.

Bikaner District, Rajasthan, India

In the Bikaner district of Rajasthan, farmers have inherited the practice of employing Khadin systems across generations. These earth embankments effectively capture and store rainwater, enabling agricultural cultivation during periods of drought.

2. Johads

Alwar District, Rajasthan, India

Alwar district has gained prominence for its successful rejuvenation of Johad systems in recent times. Pioneering the Alwar Model, the area focuses on the creation and maintenance of Johads to recharge groundwater levels. This endeavor has led to enhanced water availability for both agricultural and domestic use.

Annaikatty, Tamil Nadu, India

The village of Annaikatty in Tamil Nadu has embraced Johads as a solution to water scarcity. Through the construction of modest earthen dams, the community captures rainwater and revitalizes wells. This localized initiative has effectively restored the groundwater table and ensured sustainable water access for agricultural activities.

Difference between Johads and Khadins

Difference between Johads and Khadins are following:

Aspect	Khadin	Johad
Design	Linear embankments along contours.	Circular or saucer-shaped depressions.
Location	Sloping agricultural fields	Lower areas with larger catchment zones.
Function	Prevent soil erosion, aid irrigation.	Multiple uses: irrigation, domestic water, aquaculture.
Ownership	Often individually managed.	Typically managed collectively by the community.
Area Coverage	Smaller in size.	Can range from small to large reservoirs.
Cultural Significance	Rooted in local traditions.	Integral part of community life and rituals.
Biodiversity Impact	Minimal impact on biodiversity.	Micro Organisms can born beacuse of size larger than khadins
Modern Integration	Can be combined with modern tech.	Can be part in modern monitoring systems.
Climate Adaptation	Contributes to soil moisture during dry spells.	During rainfall helps in collecting water

Applications of Khadins and Johads

Both Khadins and Johads are leveraged as effective rainwater harvesting mechanisms, pivotal for securing water access for agriculture and allied purposes in water-scarce regions. The Applications of Khadins and Johads are the following:

Uses of Khadins

• Rainwater Capture: Khadins adeptly accumulate rainwater runoff from agricultural fields, thwarting soil erosion and facilitating groundwater recharge.
• Irrigation: Stored water in Khadins serves as irrigation water during arid periods, extending the cultivation season and heightening agricultural productivity.
• Soil Moisture Management: Khadins effectively uphold soil moisture, mitigating excessive irrigation needs.
• Crop Diversity: Water availability from Khadins encourages crop diversification, contributing to food security and increased income.

Uses of Johads

Multi-Purpose Water Source: Johads emerge as dependable water reservoirs catering to various needs, including drinking, livestock, and household requirements in rural zones.

• Irrigation: Larger Johads are instrumental in irrigation, supporting a diverse range of crops and amplifying agricultural yield.
• Fish Farming: Some communities harness Johads for pisciculture, augmenting protein consumption and income sources.
• Community Hubs: Often, Johads double up as communal spaces, symbolizing community unity and retaining cultural significance.

Advantages of Khadins and Johads

Integrating Khadins and Johads into contemporary water management strategies offers numerous advantages, particularly in regions confronting water scarcities:

• Sustainable Water Supply: Khadins and Johads promote sustainable rainwater use, lessening reliance on groundwater and surface water resources.
• Enhanced Crop Output : These systems elevate agricultural productivity by furnishing dependable water sources for irrigation, enabling multiple cropping cycles.
• Groundwater Revival: Khadins, by facilitating percolation, contribute to replenishing local aquifers, ensuring sustainable groundwater availability.
• Empowered Communities: Johads, managed collectively, nurture community involvement, cooperation, and a sense of shared responsibility for water assets.
• Erosion Check: Khadins play a pivotal role in averting soil erosion, conserving topsoil, and safeguarding agricultural land fertility.
• Cultural Conservation: Both Khadins and Johads hold cultural importance, preserving traditional knowledge and practices.

Disadvantages of Khadins and Johads

While Khadins and Johads present a range of benefits, there are also some downsides associated with these traditional water management systems:

• Maintenance Challenges: Maintaining these big structures which collect water is not an easy task because it will take some amount of labour and proper caring.
• Limited Storage Capacity: They are made based on patterns of rainfall if anytime there is no rain for longer time then, they cannot store water and also they have short limited storage capacity of water which is not able to feed much people
• Water Quality: In khadins and johads water quality is not that good because they are made in mud and also lot of animals waste, dust is also mixed with that water which makes it less suitable for drinking
• Limited Scale: With time the amount of people living in an area increases means its population increases, but they have a limited scale and cannot increase with increasing needs.
• Technological Progress: With increasing technology there are much more better methods for rainwater harvesting such as rooftop rainwater harvesting and underground water tanks etc.
