  • Right to Fair Compensation and Transparency in Land Acquisition, Rehabilitation and Resettlement Act, 2013:
    • It includes detailed provisions for resettlement and rehabilitation of those affected by land acquisition
    • This ensures that displaced families receive support to relocate and rebuild their lives, including housing. 
  • Model Tenancy Act, 2021:
    • It seeks to establish a speedy adjudication mechanism for dispute resolution, regulate renting of premises, and protect interests of landlords and tenants.  

How Balance between Development Projects and Right to Shelter can be Maintained?

  • Alternative Housing Solutions: Provide adequate alternative housing options for those displaced by development projects.
  • Legal Protections and Fair Procedures: Ensure that evictions, if necessary, are conducted in a lawful and just manner, with appropriate compensation and support.
  • Community Development and Integration: Incorporate community development programs into the project to enhance local infrastructure, services, and economic opportunities.
  • Long-Term Planning: Develop long-term strategies for urban planning and housing that integrate development goals with the need for affordable and accessible housing.

Conclusion

The Supreme Court has linked the right to shelter with the right to life, emphasising its fundamental nature and its recognition as a human right by the United Nations. While the State is duty-bound to work towards providing affordable housing, this does not mean it must construct all housing or prevent all displacement. The right to shelter, distinct from the right to land, highlights the need for clear understanding and realistic expectations. By recognizing its true essence, individuals can better advocate for their rights and seek judicial redress when necessary.

Gulf Stream and Climate Sensitivity

Source: SD

Why in News?

A recent study, published in Nature, has revealed that the Gulf Stream was significantly stronger during the last ice age (about 20,000 years ago) due to more powerful winds across the subtropical North Atlantic.

  • This finding suggests that the Gulf Stream's strength is sensitive to changes in wind patterns, which could impact future climate if these winds weaken due to climate change.

Note:

  • The Gulf Stream is a powerful ocean current that brings warm water from the Gulf of Mexico up the eastern coast of North America.
  • It then crosses the Atlantic Ocean, influencing the climate of Western Europe by making it warmer than it would otherwise be.

What are the Key Highlights of the Study?

  • Research Methodology: Analysis of fossil foraminifera from sediment cores off North Carolina and Florida was used to gauge the prehistoric Gulf Stream's strength.
    • Findings showed the Gulf Stream was twice as deep and fast during the last ice age.
  • Impact on Climate: Despite the strength of the Gulf Stream, the global climate was much colder than at present.
    • A weakened Gulf Stream in the future could limit tropical heat reaching Europe, potentially cooling the continent and raising sea levels in North America.
  • Role of Atlantic Meridional Overturning Circulation (AMOC): The Gulf Stream is part of the AMOC, which involves both deep water formation and wind patterns. 
    • Climate change-induced disruptions, such as melting glacial water from Greenland, could weaken the AMOC.
    • A weakened AMOC could significantly cool Europe by 10 to 15 degrees Celsius, disrupt agriculture, and alter weather patterns.
    • AMOC Loops and Climate Impact:
      • The AMOC should be viewed as interconnected loops (subtropical and subpolar) rather than a simple conveyor belt.
        • Different parts of the AMOC may respond uniquely to climate change, affecting climate impacts.

Atlantic Meridional Overturning Circulation (AMOC)

  • About: AMOC is a major system of ocean currents that forms part of the global ocean conveyor belt or ThermoHaline Circulation (THC), distributing heat and nutrients across the world's oceans.
  • Working of AMOC: AMOC transports warm surface waters from the tropics to the Northern Hemisphere, where the water cools and sinks. It then returns as a bottom current through the South Atlantic, eventually being spread to all ocean basins by the Antarctic Circumpolar Current (ACC), the only current circulating the globe.
  • Implications of Decline of AMOC: A weakened AMOC, including the Gulf Stream, could cause Europe to become very cold, reduce rainfall, and potentially influence El Nino and shift monsoons in South America and Africa.
  • Causes of Decline: Predictions suggest global warming may weaken major ocean systems. Melting Greenland ice and the "Last Ice Area" contribute freshwater that lowers water salinity and density, impeding the AMOC flow. Increased precipitation and river runoff in the Indian Ocean may also impact AMOC.
  • Importance: AMOC is crucial for redistributing heat and regulating global weather patterns.

Source: PIB

Why in News?

Recently,  Magnetofossils, fossilised magnetic particles from magnetotactic bacteria, have been discovered in rock varnish layers in Ladakh.

  • Rock varnish is a dark brown to black coating that covers stable, subaerially exposed rock surfaces in arid and semiarid regions.

What are the Key Highlights of the Study?

  • Findings:
    • The analysis of the rock varnish samples from Ladakh revealed higher concentrations of oxidized manganese (Mn4+) and carboxylic acid functionality, indicating organic signatures.
    • These findings suggest that the rock varnish in Ladakh, a potential Martian analogue site, contains enriched concentrations of magnetic minerals likely derived from biotic sources.
      • Magnetic minerals are those that preserve a record of the Earth's magnetic field from when they formed and can be found in rocks, sediments, and soils.
  • Significance:
    • The study offers valuable insights for astrobiology by demonstrating how life can thrive in extreme environments, such as Ladakh, the "cold desert of India."
    • The findings are crucial for planning future space missions by Indian Space Research Organisation (ISRO) and other space agencies, including Mars exploration, where identifying habitable environments is a primary goal.
      • Identifying biotic signatures in rock varnish helps scientists target potential biosignatures on Mars and other planets, supporting the search for extraterrestrial life
        • A biosignature is any characteristic, element, molecule, substance, or feature that can be used as evidence for past or present life.

Magentofossils

  • About:
    • Magnetofossils refer to fossilised remains of magnetotactic bacteria that contain magnetic minerals.
      • Magnetotactic bacteria leave fossilised magnetic particles in geological records.
  • Magnetotactic Bacteria:
    • Magnetotactic bacteria are mostly prokaryotic organisms that arrange themselves along the earth’s magnetic field. It was discovered by Salvatore Bellini in 1963.
    • These organisms follow the magnetic field to reach places that had optimal oxygen concentration. This process is facilitated by the presence of iron-rich crystals within their cells. 
      • Magnetotactic bacteria create tiny crystals of magnetite or greigite within their cells to navigate changing oxygen levels and sediment saturation in water bodies.
      • Crystals within magnetotactic bacteria are arranged in a chain configuration through magnetotaxis.
    • Rare giant magneto fossils are less common than conventional magnetic fossils, these are likely produced by eukaryotes rather than bacteria.

Recently, the Supreme Court has provided relief to homebuyers in the National Capital Region (NCR) under the Subvention scheme.

  • The Supreme Court has instructed banks not to take coercive action against individuals who have not received possession of their flats.
  • Subvention Scheme
    • In real estate, subvention schemes involve a tripartite agreement between the buyer, banker, and developer. 
    • The buyer pays 5-20% upfront, while the bank loans the rest to the developer.
    • The developer pays the loan interest until the buyer takes possession, after which the buyer's EMI starts. 
    • This scheme boosts sales for developers and delays EMI payments for buyers.
    • However, in the present case many builders have defaulted on these payments.
  • Subsidy:
    • Subsidy is direct financial assistance provided by the government or another entity to reduce the cost of a product or service for the consumer. 
    • This leads to a decrease in the price of the product or service for the consumer. For example, government subsidies on food grains, fertilizers, or fuel.
