Great Himalayan National Park:

The Ministry of Environment recently declared a 326.69 sq.km. area around the Great Himalayan National Park in Himachal Pradesh as an eco-sensitive zone.

  • It is a high altitude national park located in Kullu District of Himachal Pradesh.\
  • Nestled in the far Western Himalayas, the park comprises four valleys: the Tirthan Valley, the Sainj Valley, the Parvati Valley, and the Jiwa Nal Valley.
  • It is surrounded by steep ridges and permanent snow on its northern, eastern, and southern
  • The GHNP is situated adjacent to Pin Valley National Park, Rupi-Bhaba Wildlife Sanctuary, and the Tirthan and Sainj Wildlife Sanctuaries.
  • The park is a stunning mix of lush coniferous forests, meadows, glaciers, and mountain peaks.
  • It was awarded UNESCO World Heritage Site status in 2014.
  • Vegetation grows in well-defined altitude zones, beginning with rather open, subtropical forests at the lowest valley bottoms, gradually grading to mixed forests of horse chestnut, evergreen oak, spruce, and deodar, then to rusty-leaved kharsu oak, spruce, and fir in the upper temperate zone.
  • Further up is a subalpine zone of birches, stunted firs, and rhododendron bushes, followed by the higher alpine areas where vegetation is reduced to grasses, herbs, and low shrubs, such as juniper.
  • The park is home to 31 mammals, including the elusive snow leopard, the majestic Himalayan brown bear, and the vibrant blue sheep, or bharal.
  • Other notable residents include the Himalayan tahr, musk deer, and serow.
  • Birdlife in the park is equally diverse, with 209 species recorded, such as the endangered western tragopan and the impressive lammergeiers, alongside the Himalayan griffon vulture and golden eagle.

Allele : Study

A study from South Africa finds that while protective HLA-B alleles once aided survival and reduced HIV transmission before Antiretroviral therapy, widespread ART use has significantly slowed this natural selection-driven genetic shift.

  • An allele is a variant form of a gene.
  • Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome.
  • Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
  • Each pair of alleles represents the genotype of a specific gene.
  • Genotypes are described as homozygous if there are two identical alleles at a particular locus and as heterozygous if the two alleles differ.
    Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism.
  • Some alleles are dominant or recessive. When an organism is heterozygous at a specific locus and carries one dominant and one recessive allele, the organism will express the dominant phenotype.
  • This genetic diversity allows offspring to inherit traits from both parents while exhibiting unique characteristics.
  • For example, in hair color, dark hair is typically dominant over light hair; a child may inherit light hair only if both parents pass on the recessive allele.
  • All genetic traits are the result of the interactions of alleles.
  • Mutation, crossing over, and environmental conditions selectively change the frequency of phenotypes (and thus their alleles) within a population.

SVAMITVA Scheme: In News

The rural property ownership scheme, SVAMITVA, is emerging as a potent tool for formalisation of residential land, improving the financial standing of gram panchayats, and making a positive impact on the rural economy, says a survey by IIM Ahmedabad.

  • The Survey of Villages and Mapping with Improvised Technology in Village Areas (SVAMITVA) is a central sector scheme of the Ministry of Panchayati Raj.
  • It was launched nationwide on National Panchayati Raj Day, 24th April 2021, after successful completion of the pilot phase of the scheme (2020-2021) in 9 states.
  • It aims to empower rural citizens with property cards, enabling access to credit, dispute resolution, and better planning.
  • It provides a ‘Record of Rights’ to village household owners with the issuance of legal ownership cards (property cards/title deeds) to the property owners by mapping land parcels using drone technology.
  • The mapping shall be done across the country in a phased manner. It generates high-resolution and accurate maps to confer ownership property rights.
  • The scheme seeks to achieve the following objectives:
    • To bring financial stability to the citizens in rural India by enabling them to use their property as a financial asset for taking loans and other financial benefits.
    • Creation of accurate land records for rural planning.
    • Determination of property tax, which would accrue to the Gram Panchayats (GPs) directly in States where it is devolved or else add to the State exchequer.
    • Creation of survey infrastructure and GIS maps that can be leveraged by any department for their use.
    • To support the preparation of a better-quality Gram Panchayat Development Plan (GPDP) by making use of GIS maps.
    • To reduce property-related disputes and legal cases.
  • The applicant should have a property in a rural inhabited (Abadi) area.
  • Exclusions: Agricultural lands are not covered under this scheme.
  • It is implemented by the Survey of India (SoI) with the National Informatics Centre Services Inc. (NICSI) as the technology partner.
  • In the States, the Revenue Department/Land Records Department will be the Nodal Department and shall carry out the scheme with the support of the State Panchayati Raj Department.

Udayan Fort:

The historic Udyan Fort in Kaushambi, dating back nearly 2,500 years to the era of the ancient Vatsa Mahajanapada, is set to undergo restoration following official approval, officials said recently.

  • Udayan Fort, also known as Udayan Kila, is a historical site located in the Kaushambi district of Uttar Pradesh.
  • It is located on the banks of the Yamuna River.
  • The fort is associated with King Udayana, the ruler of the Vatsa kingdom—one of the 16 Mahajanapadas of ancient India.
  • It served as the capital fort of the Vatsa kingdom during the 6th century BCE.
  • King Udayana was known for his military strength, diplomatic skills, and cultural patronage.
  • According to Buddhist and Jain texts, Udayana had connections with both Lord Buddha and Mahavira, who visited Kaushambi and contributed to its spiritual growth.
  • The fort thus played a key role in shaping the early political and religious landscape of the region.
  • Architectural Remains and Layout:
    • The layout of the fort suggests a well-planned administrative and residential zone, complete with defensive structures and public buildings.
    • The defensive structures include thick brick walls, earth ramparts, and bastions rising up to 50 to 60 feet, along with evidence of protective moats or trenches.
    • The site is characterized by extensive brickbats scattered across the ground, hinting at the density of buildings that once stood inside the fortress.
    • Archaeologists have unearthed pottery, coins, and ancient tools from the area, providing evidence of a thriving settlement.

Spinal Muscular Atrophy:

Persons living with Spinal Muscular Atrophy (SMA), and parents have written to Prime Minister of India seeking urgent intervention to ensure nationwide access to generic Risdiplam under the National Policy for Rare Diseases (NPRD).

  • It is a rare and progressive neuromuscular disorder that leads to muscle weakness and can cause life-threatening complications.
  • It is a debilitating genetic condition which affects motor neurons that control movement, and leads to progressive muscle weakening.
  • Most forms of SMA are caused by mutations of the survival motor neuron 1 gene (SMN1) on the fifth chromosome, resulting in insufficient expression levels of the SMN protein.
  • There are five subtypes of SMA- type 0, 1, 2, 3, 4. Healthcare providers classify them based on the age of onset, as well as the severity and life expectancy.
  • Symptoms of Spinal Muscular Atrophy:
    • Its symptoms vary and may be mild or disabling, but involve a weakness of the muscles that control movement.
    • The weakness in SMA tends to be more severe in the muscles that are close to the center of your body than in the muscles farther away from your body’s center.
  • Treatment: Unfortunately, there isn’t a cure for SMA. Treatment for SMA mainly seeks to manage symptoms and prevent complications.
