Cholistan Desert
Why in news?
a. Recently, the Government of Pakistan decided to halt its ambitious canals project
aimed at extending irrigation networks into the Cholistan Desert.
About Cholistan Desert:

- Location and Background:
- The Cholistan Desert lies in the southern part of Punjab province, Pakistan, bordering the Thar Desert of India.
- It spans approximately 26,300 square kilometres and is characterised by extreme aridity, sand dunes, and sparse vegetation.
- The region relies heavily on traditional water sources like tobas (natural ponds) and rainwater harvesting for survival.
- Given its harsh conditions, government initiatives have long focused on improving water access and boosting agriculture through canal networks sourced from the Indus River system.
- The Cholistan Canal Project:
- The Cholistan Canal Project was an ambitious plan by the Government of Pakistan to construct a network of canals diverting water from the Indus River system to the Cholistan Desert in southern Punjab.
-
- The project's main goal was to convert arid desert land into fertile agricultural fields, thereby supporting food security, economic development, and population resettlement in one of the harshest regions of Pakistan.
- Reason Behind the Halt:
- Despite its economic promises, the project faced strong opposition from Sindh province, the lower riparian region of the Indus River.
- Sindh protesters and political leaders argued that the new canals would divert precious Indus water upstream, severely reducing water availability for agriculture, drinking, and industry in Sindh, which is already grappling with chronic water shortages.
- They warned that this would violate the spirit of the 1991 Indus Water Accord, which governs the equitable distribution of river water between provinces.
- Concerns also arose over the ecological impact of further water extraction from the Indus, which could accelerate desertification, reduce riverine ecosystems, and threaten the livelihoods of millions who depend on consistent water flows in Sindh.
Sandy Cay
Why in news?
a. The Philippines has strongly criticised China's recent actions around Sandy Cay in the South China Sea, labelling them as "desperate and cheap stunts."
About Sandy Cay:

- Location:
- Sandy Cay is a group of small sandbars located approximately four nautical miles west of Pag-asa Island (part of the Kalayaan Island Group), within the Philippines’ Exclusive Economic Zone (EEZ) in the West Philippine Sea (South China Sea).
- It lies strategically near Philippine-occupied territory and is a critical feature in ongoing territorial assertions in the region.
- Territorial Disputes:
- The Philippines firmly considers Sandy Cay as part of its sovereign territory.
- Recently, tensions flared when Chinese personnel reportedly raised a Chinese flag and conducted inspection activities on the sandbar, actions that Philippines condemned as "desperate and cheap stunts" aimed at misleading international opinion and bolstering illegitimate claims.
- The Speaker of the Philippine House of Representatives emphasised that Sandy Cay falls well within Philippine jurisdiction, citing the 2016 ruling of the Permanent Court of Arbitration (PCA) in The Hague, which invalidated China's sweeping claims over the South China Sea, including areas surrounding Sandy Cay.
- South China Sea Context:
-
- The South China Sea is a hotbed of overlapping territorial claims involving China, the Philippines, Vietnam, Malaysia, Brunei, and Taiwan.
- China’s "nine-dash line" claims nearly the entire sea, despite the PCA’s ruling
rejecting its historical rights argument.
-
- The sea holds vast untapped reserves of oil and natural gas, making it economically and strategically vital.
- The Philippines' National Security Council (NSC) and National Task Force-West Philippine Sea reaffirmed Philippine sovereignty by launching a coordinated maritime operation involving the Navy, Coast Guard, and Police-Maritime Group around Sandy Cay and nearby Pag-asa Cays.
- Officials urged China to cease provocative actions and respect international law to prevent further escalation in the region, where tensions have increasingly strained Philippines-China relations.
Saraswati River
Why in news?
a. Saraswati Board plans to divert Sutlej River water into the Saraswati’s believed course, collaborating with Haryana Space Centre for mapping.
About Saraswati River:

- Location:
- The Saraswati River is believed to have flowed through parts of modern-day Haryana, Rajasthan, and Gujarat before emptying into the Arabian Sea.
- Based on geological and satellite studies, the ancient river's course is associated with the present-day Ghaggar-Hakra river system.
- Traces of its paleo-channels have been found near Kurukshetra, Yamunanagar, and Sirsa in Haryana, and extending through Cholistan in Pakistan.
- The river is thought to have originated from the Himalayas, particularly from the
Bandarpunch glacier, and flowed parallel to the Yamuna and Sutlej rivers.
-
- Various efforts by the Indian government, including satellite imagery mapping by the Haryana Space Applications Centre (HARSAC), are underway to revive and trace its ancient course.
- Cultural and Religious Significance:
- The Saraswati River holds immense cultural and religious significance in
Hindu tradition.
