  • Species in news: Atlantic Menhaden

    atlantic

    Central Idea

    • Researchers have discovered that the population of ospreys, a fish-eating bird, is facing a decline due to the decreasing numbers of Atlantic menhaden, their primary food source.
    • The depletion of menhaden, a small silvery fish, is attributed to commercial fishing practices.
    • The decline in osprey reproduction reflects the broader ecological impact of reduced menhaden numbers.

    About Atlantic Menhaden

    • Atlantic menhaden, scientifically known as Brevoortia tyrannus, is a species of fish belonging to the Clupeidae family.
    • They are commonly found along the Atlantic coast of North America, ranging from Florida to Nova Scotia.
    • Atlantic menhaden play a vital ecological role and have significant commercial and ecological importance.

    Importance of Atlantic Menhaden

    • Role in Coastal Ecosystem: Menhaden play a crucial role in the ecology of coastal waters along the Eastern Seaboard, providing sustenance for larger fish, marine mammals, and birds.
    • Nutrient-Rich and Filtering Capacity: Menhaden are nutrient-rich, containing omega-3 fatty acids, and they filter substantial quantities of ocean water while consuming smaller organisms like plankton.

    Commercial Fishing Impact

    • Increased Catch Allowance: The Atlantic States Marine Fisheries Commission raised the allowable catch of menhaden to 233,550 metric tons for the next two years, a 20% increase from previous years.
    • Fishery Quota: The commission maintained a quota of 51,000 metric tons for the Chesapeake Bay’s reduction fishery, where menhaden are used for bait and fish products.
    • Ecological Concerns: Critics argue that the removal of significant menhaden quantities is degrading the ecosystem, negatively affecting species like ospreys and striped bass that rely on menhaden.

    Low Reproductive Numbers and Menhaden Depletion

    • In mid-June, researchers found only three young ospreys out of 84 nests checked in Mobjack Bay, part of the Chesapeake Bay.
    • Scientists at the College of William & Mary, monitoring the local osprey population for over 50 years, recorded the lowest reproductive number.
    • The decline in breeding success is attributed to the depletion of Atlantic menhaden, the osprey’s primary food source.

    Lawsuit and Ecosystem Protection

    • Recreational Fishermen Lawsuit: A group of recreational fishermen from Maryland sued the Virginia Marine Resources Commission, claiming it contributed to the menhaden decline by endorsing quotas that harm fish populations and the recreational fishing industry.
    • Commercial Fishing Practices: Critics highlight the negative impact of industrial techniques used by companies like Omega Protein, which catch menhaden in unsustainable quantities, contributing to the decline of other species and damaging ecosystems.
    • Restoring Menhaden Stocks: Non-profit organizations advocate for rebuilding menhaden populations along the Atlantic and Gulf of Mexico coasts to maintain a balanced ecosystem.

    Positive Signs beyond Chesapeake Bay

    • Menhaden Recovery: Outside the Chesapeake Bay, menhaden populations have increased since the Atlantic commission took measures to address overfishing in 2012, leading to a recovery of the fish population within two years.
    • Ecological Impact: The recovery of menhaden populations has brought back various predators such as humpback whales, tuna, sharks, and bald eagles off the coasts of New York and New Jersey.

    • Achievements: Over 40,000 turtles have been released from the center, with approximately 28,000 turtles released during the initial phase of the GAP.
    • Renewed Focus: The center has gained renewed attention and support following the launch of the Namami Gange Programme in 2014, a flagship initiative of the Central government aimed at combating pollution and restoring the river’s ecological balance.

    Strengthening the Ganges Clean-up Efforts

    • Turtle Population: The center nurtures around a dozen turtle species, including herbivores and carnivores, which are vital in maintaining a balanced ecosystem.
    • Collection of Eggs: The Forest and Wildlife Department collects turtle eggs from the coastal areas of the Chambal region.
    • Controlled Hatching Process: The eggs are carefully monitored for 70 days in a specially designed room for hatching. They are buried in sand-filled wooden boxes placed on a water-filled ground with bricks on top.
    • Monitoring and Care: After hatching between June and July, the turtles are observed and nurtured in an artificial pond for two years to ensure their health and readiness for release into the river.

    Role of Turtles in Ganges Restoration

    • Impact on Water Quality: Turtles contribute to improving the quality of the Ganges by feeding on meat and waste products present in the river.
    • Positive Indicators: Water quality assessments conducted by the Namami Gange Programme reveal improvements in biochemical demand (BOD), faecal coliform (FC), and dissolved oxygen (DO) levels.
    • Government’s Findings: The Uttar Pradesh Government confirmed that the pH levels at various locations, including Varanasi, meet bathing water quality criteria, while DO, BOD, and FC levels have shown improvement at 16, 14, and 18 out of 20 locations, respectively.

  • Forest (Conservation) Amendment Bill, 2023

    Central Idea

    • A parliamentary committee has given its endorsement to the Forest (Conservation) Amendment Bill, which seeks to amend the Forest (Conservation) Act, 1980.
    • The proposed amendments have attracted objections and controversies, raising concerns about dilution of forest protection and potential impacts on biodiversity, forest rights, and national security.

    Forest (Conservation) Amendment Bill, 2023: An overview

    • The Forest (Conservation) Act, 1980, safeguards India’s forest land from unauthorized non-forestry use and allows for compensation in case of diversion.
    • Previous amendments aimed to expand protection, but the current amendments focus on removing ambiguities and clarifying the Act’s applicability on various types of land.
    • The amendments emphasize promoting tree cover, carbon sinks, national security infrastructure, and livelihood opportunities for forest-dwelling communities.

     

    Forest (Conservation) Act, 1980

    • It is the principal legislation that regulates deforestation in the country.
    • It prohibits the felling of forests for any “non-forestry” use without prior clearance by the central government.
    • The clearance process includes seeking consent from local forest rights holders and from wildlife authorities.
    • The Centre is empowered to reject such requests or allow them with legally binding conditions.
    • Process of approval for the diversion of forest land culminates after issuance of final diversion order by the State Government or UT concerned which authorises use of forest land for intended purpose and hands over the land to the user agency.

    Key features

    • Inclusion and Exclusion of Land: The Bill amends the Forest (Conservation) Act, 1980 to make it applicable to land notified as a forest under the Indian Forest Act, 1927 or in government records after the 1980 Act came into effect. Land converted to non-forest use before December 12, 1996, will not fall under the Act’s purview.
    • Exemptions: Certain types of land are exempted from the Act, including land within 100 km of India’s border required for national security projects, small roadside amenities, and public roads leading to habitation.
    • Assignment of Forest Land: The state government requires prior approval from the central government to assign forest land to any private or government entity. The Bill extends this requirement to all entities and allows assignment on terms and conditions specified by the central government.
    • Permitted Activities: The Bill expands the list of permitted activities in forests, including establishing check posts, fencing, bridges, running zoos, safaris, and eco-tourism facilities.

    Controversial parts of the Amendment

    • Dilution Concerns: Some critics argue that the amendments dilute the Supreme Court’s 1996 Godavarman case judgment, which extended protection to forests not officially classified as such.
    • Geographically Sensitive Areas: Projects within 100 km of international borders or the Line of Control would no longer require forest clearance, which raises concerns about the environment and security.
    • Deemed Forests and Tourism: Central protection for deemed forests and restrictions on activities like tourism could be compromised, affecting biodiversity conservation and forest integrity.
    • Impact on Forest Cover: Exempting land near border areas for national security projects may adversely affect forest cover and wildlife in northeastern states, which have high forest cover and are biodiversity hotspots.
    • Potential Adverse Effects: Blanket exemptions for projects like zoos, eco-tourism facilities, and reconnaissance surveys may have negative consequences for forest land and wildlife.

    Opposition and Criticism

    • Northeast States’ Opposition: Some northeastern states objected to forest land being used for defense purposes without their consent.
    • Environmental Groups’ Concerns: Environmental organizations criticized the removal of Central protection for deemed forests and allowing tourism in these areas, risking biodiversity and forest conservation.
    • Name Change Controversy: The proposal to change the name of the Act to Van (Sanrakshan Evam Samvardhan) Adhiniyam faced objections for being non-inclusive and excluding certain regions’ populations.

    Conclusion

    • The Forest (Conservation) Amendment Bill, despite attracting objections and controversies, has received the endorsement of the parliamentary committee.
    • The proposed amendments aim to bring clarity to the Act’s applicability and promote tree cover, national security infrastructure, and livelihood opportunities.

  • Miyawaki Technique of Urban Afforestation

    Central Idea: Prime Minister during his latest ‘Mann ki baat’ episode spoke about Miyawaki plantation, the Japanese method of creating dense urban forests in a small area.

    Try this question:

    Q.The Miyawaki Forests technique has to potential to revolutionize the concept of urban afforestation in India. Discuss.

    Miyawaki Method

    • Miyawaki method is a method of urban afforestation by turning backyards into mini-forests.
    • It includes planting trees as close as possible in the same area which not only saves space, but the planted saplings also support each other in growth and block sunlight from reaching the ground, thereby preventing the growth of weed.
    • Thus the saplings become maintenance-free (self-sustainable) after the first three years.
    • It helps to create a forest in just 20 to 30 years while through conventional methods it takes anywhere between 200 to 300 years.

    The technique

    miyawaki

    • The native trees of the region are identified and divided into four layers — shrub, sub-tree, tree, and canopy.
    • The quality of soil is analysed and biomass which would help enhance the perforation capacity, water retention capacity, and nutrients in it, is mixed with it.
    • A mound is built with the soil and the seeds are planted at a very high density — three to five sapling per square meter.
    • The ground is covered with a thick layer of mulch.
