1. Deep-Sea Mining: Uncovering Lasting Ecological Impacts

Context: A recent study published in Nature, titled ‘Long-term Impact and Biological Recovery in a Deep-Sea Mining Track,’ reveals alarming findings about the effects of deep-sea mining. Conducted by scientists from Britain’s National Oceanography Centre, the research shows that an area of the Pacific Ocean seabed mined over 40 years ago has not fully recovered.

The results arrive at a critical time, as 36 countries recently gathered at a UN International Seabed Authority (ISA) meeting in Jamaica to debate whether mining companies should be permitted to extract valuable metals from the ocean floor.

What is Deep-Sea Mining?

Deep-sea mining refers to the extraction of valuable minerals and metals from the ocean floor, often located at depths beyond 200 meters. The process is divided into three main categories:

1. Collecting Polymetallic Nodules: Harvesting metal-rich rocks scattered across the ocean floor.
2. Mining Seafloor Sulphide Deposits: Extracting materials from hydrothermal vents, often rich in precious metals.
3. Removing Cobalt Crusts: Stripping minerals from underwater mountains and volcanic structures.

Why It Matters:

Deep-sea mining is attracting interest because of its potential to provide essential materials such as nickel, cobalt, rare earth elements, and copper—all critical for technologies like renewable energy systems, electric vehicles, and everyday electronics.

The findings of this study are expected to play a crucial role in shaping future regulations by the International Seabed Authority (ISA).

Key Takeaways:

• The research suggests that while partial recovery is possible, full restoration of deep-sea ecosystems could take decades or longer.
• Data from this study contributes to the Seabed Mining and Resilience to Experimental Impact (SMARTEX) project, which aims to support informed decision-making about the ecological and societal impacts of deep-sea mining.

The Future of Deep-Sea Mining: Clarion Clipperton Zone (CCZ):

The Clarion Clipperton Zone (CCZ) is a mineral-rich region in the North Pacific Ocean, located between Hawaii and Mexico. It is known for its abundance of polymetallic nodules containing valuable minerals such as:

• Manganese
• Nickel
• Copper
• Cobalt

These materials are essential for manufacturing electric vehicles, solar panels, and other clean energy technologies.

The Debate Continues:

As interest in deep-sea mining grows, the ISA is currently evaluating whether and under what conditions mining should be allowed. The recent study adds substantial weight to the argument for a moratorium on deep-sea mining, particularly in ecologically sensitive areas like the CCZ.

Conclusion: A Call for Precaution:

The findings underscore the lasting impact of deep-sea mining on fragile marine ecosystems. While technological advancements and resource demands continue to drive interest in deep-sea mining, the long-term ecological risks cannot be ignored.

Future regulations must be guided by robust scientific research, prioritizing sustainability, biodiversity protection, and responsible resource management.

2. Sarhul Festival: Jharkhand’s Grand Celebration of Nature and Adivasi Culture

Context: The Adivasi communities of Jharkhand and the Chhotanagpur region are set to celebrate the Sarhul Festival on April 1, 2025. This grand occasion marks the New Year and the much-anticipated arrival of spring.

What is Sarhul?

Sarhul is a New Year festival celebrated by the tribal communities of Jharkhand as part of the Sarna religion. Held in the Hindu month of Chaitra, it occurs three days after the new moon. The festival is a vibrant celebration of spring and a reverent homage to nature.

Nature Worship at the Heart of Sarhul:

• The term Sarhul literally means “worship of the Sal tree”. The Sal tree is considered the abode of Sama Maa, the village-protecting deity. This festival, deeply rooted in nature worship, reflects the Adivasi’s profound connection to the environment.

Symbolizing the Union of Sun and Earth:

• Sarhul symbolizes the harmonious union of the Sun and the Earth. The pahan (male priest) represents the Sun, while his wife, the pahen, symbolizes the Earth. This connection highlights the importance of sunlight and soil for sustaining life.

A Festival Celebrating Life’s Cycle:

• Sarhul marks the renewal of life. Only after the rituals are completed do Adivasis commence agricultural activities such as ploughing, sowing, and forest gathering. This tradition emphasizes the festival’s deep-rooted ties to nature and sustenance.

Diverse Traditions Among Tribes:

• While Sarhul is celebrated by various tribes, including the Oraon, Munda, Santal, Khadia, and Ho, each group has its own unique customs and names for the festival.

From Hunting to Agriculture:

• Originally focused on hunting, the festival has evolved over time into an agriculture-based celebration, mirroring the changing lifestyle of Adivasis in the Chhotanagpur region.

Sarhul’s Journey Across Lands:

• During the 19th and early 20th centuries, Adivasi communities took Sarhul with them when they were sent as indentured laborers. As a result, Sarhul is now celebrated in places like Assam’s tea gardens, the Andaman and Nicobar Islands, Nepal, Bangladesh, and Bhutan.

The Three-Day Celebration:

Day One: Preparations

• The festival kicks off with decorations at homes and Sarna Sthals (sacred groves), featuring triangular red and white Sama flags. The pahan observes a fast and collects ceremonial water, while the community prepares the sacred sites and gathers Sal flowers.

Day Two: Main Rituals

• At the Sarna Sthal, villagers offer Sal flowers to the deity and sacrifice a rooster to ensure prosperity. The pahan sprinkles holy water while villagers perform traditional dances like Jadur, Gena, and Por Jadur. Young men participate in ceremonial fishing and crab-catching.

Day Three: Community Feast and Blessings

• The festival concludes with a grand community feast, featuring handia (rice beer) and traditional dishes. The pahan blesses the villagers, marking the end of the celebrations.

Transformation Over the Years:

Evolving Symbol of Identity:

• In the 1960s, Baba Karthik Oraon, a notable Adivasi leader, initiated a procession from Hatma to Siram Toli Sarna Sthal. Today, these processions have become a central feature, showcasing Adivasi identity and fostering a sense of community pride.

Debate Over Religious Identity:

• While some tribal groups advocate for recognizing the Sarna religion as distinct from Hinduism, others argue that Adivasis are inherently part of Hindu culture. This debate continues to shape identity politics in the region.

A Festival Honoring Nature:

Nature at the Center:

• Unlike other festivals that celebrate human achievements, Sarhul is dedicated to nature, with the Sal tree as its central symbol. The festival is devoid of idols or temple processions, focusing purely on the worship of nature.

Preserving Adivasi Heritage: As urbanization impacts tribal traditions, Sarhul emerges as a cultural movement reinforcing Adivasi identity. It offers a valuable lesson to modern celebrations—teaching us that true festivity lies in respecting nature, not in extravagant displays.
