What is the Jojari River?

The Jojari River is a seasonal desert stream in western Rajasthan, flowing through Nagaur and Jodhpur districts. It is the main right-bank tributary of the Luni River, joining it near Khejalda Khurd in Jodhpur. Unlike other Luni tributaries that originate in the Aravalli Range, the Jojari rises near Pondlu village in the desert plains, giving it a unique hydrological character.

The river is primarily fed by monsoon rainfall and is prone to drying up in summer. Despite its seasonal nature, it supports local agriculture and is culturally significant. However, Jojari River has suffered severe degradation from industrial pollution and encroachment.

Why is the Jojari River in News?

The Jojari River came into the spotlight after the Supreme Court imposed an interim ban on all construction within 100 metres of the river and on polluting activities within 500 metres. The court acted to protect the river’s degraded ecosystem, which has been heavily polluted by untreated industrial effluents containing heavy metals like lead and cadmium from textile dyeing and chemical industries.

This intervention highlights the growing judicial concern over river pollution and encroachment, similar to actions taken for the Ganga and Yamuna. The ruling underscores the need for stricter enforcement of environmental laws. For official court orders, refer to the Supreme Court website for the full judgment.

Key Features of Jojari River

Several geographical and ecological features define the Jojari River. These are important for understanding its significance and vulnerability.

• Location: Flows through Nagaur and Jodhpur districts of Rajasthan.
• Origin: Rises in the desert plains, not the Aravalli Range, making it distinct.
• Course: Flows northeast to southwest, merging into the Luni near Khejalda Khurd.
• Right-bank tributary: It is the main right-bank tributary of the Luni.
• Seasonal: It is a desert stream, largely dry outside the monsoon season.

Challenges Facing Jojari River

The Jojari River faces multiple anthropogenic pressures that threaten its ecological health. These challenges are emblematic of river pollution in industrial areas.

• Industrial pollution: Untreated effluents from textile dyeing and chemical plants discharge heavy metals like lead and cadmium.
• Encroachment: Unauthorised construction near the riverbanks obstructs natural flow and aggravates flooding.
• Water scarcity: Over-extraction of groundwater and reduced rainfall exacerbate seasonal dryness.
• Lack of treatment facilities: Inadequate common effluent treatment plants (CETPs) allow untreated discharge.
• Weak monitoring: Sparse water quality monitoring makes enforcement difficult.

Way Forward for Jojari River

To revive the Jojari River, immediate steps include enforcing the Supreme Court’s ban, setting up and upgrading CETPs for industries, and implementing strict pollution control measures. Regular monitoring of water quality and installation of real-time sensors can help detect violations.

Long-term solutions involve restoring the river’s flow through rainwater harvesting and groundwater recharge, as well as creating green buffers along the banks. Public awareness and community participation can sustain these efforts. For best practices in river rejuvenation, refer to the Ministry of Water Resources guidelines.
