  • Why Zoning of Flood Plains is important?

    flood plain

    Central Idea

    • Punjab has been grappling with severe floods for over a month, predominantly affecting villages along rivers like Sutlej, Beas, Ravi, and Ghaggar.
    • These areas, known for their fertile flood plains, have been hit the hardest due to floods exacerbated by encroachments and construction.

    Flood Plains and their Significance

    • Flood plains adjacent to rivers serve as natural defences against inland flooding. Maintained without concrete encroachments, they absorb excess water, safeguarding other regions.
    • Properly managed flood plains also aid in recharging groundwater levels and maintaining the water table.

    What is Zoning of Flood Plains?

    • Zoning of flood plains refers to the practice of categorizing and regulating different areas within flood-prone regions based on their vulnerability to flooding and the intensity of flood events.
    • This aims to manage land use and construction activities in these areas to minimize the risks associated with flooding, protect communities and infrastructure, and maintain the natural functions of flood plains.
    • It involves designating specific zones within flood-prone regions and establishing regulations and guidelines for development, construction, and land use in each zone.

    Current Scenario: No Zoning in Punjab

    • National Green Tribunal (NGT): NGT guidelines state that construction should not occur within 500 meters of a river’s central lining.
    • Punjab’s Lag: Despite NGT’s directives and the need for floodplain zoning, Punjab has yet to initiate the process. Encroachments persist, putting riverside villages at perpetual risk.

    Impact of Inaction: People and Ecosystems Affected

    • Risk to People and Property: Unregulated construction leads to increased flood risks further inland, causing greater harm during floods.
    • Environmental Impact: Concretization of flood plains delays water drainage and affects soil fertility and quality.

    Flood Prone Districts and National Issue

    • Districts at Risk: Many districts including Ropar, Ludhiana, Ferozepur, Patiala, and more fall within flood plains, magnifying the need for preparedness.
    • Nationwide Challenge: While only four states have adopted flood plain zoning in principle, implementation has been insufficient. Even those that adopted zoning have not effectively delineated and demarcated flood plains.

    Activists’ Advocacy

    • Activists’ Concerns: Environmental activists and NGOs in Punjab have been advocating for flood plain zoning to mitigate risks.
    • Urgent Implementation: Immediate initiation and completion of flood plain zoning are crucial to safeguard lives, property, and ecosystems from devastating floods.

    Conclusion

    • The recent floods in Punjab underline the urgency of flood plain zoning to avert catastrophe.
    • By adopting effective zoning measures, the state can shield its citizens and environment from the damaging impacts of unchecked construction and flooding.
    • It is imperative that Punjab takes swift action to implement flood plain zoning and thereby protect its vulnerable regions from the perpetual threat of floods.

  • Chandrayaan-3 landing site called ‘Shiv Shakti’

    shiv shakti

    • The replication of this genetic information in nearly a trillion cells during development results in a complex mosaic of cellular diversity.
    • Despite remarkable DNA replication accuracy, mutations still occur.

    What are Somatic Genes?

    • Somatic genetic variants, also known as somatic mutations or somatic alterations, are genetic changes that occur in the cells of an organism’s body (somatic cells) during its lifetime.
    • These mutations are distinct from germline mutations, which are inherited from parents and are present in every cell of an individual’s body.
    • Somatic mutations are acquired after conception and are not passed on to future generations.
    • Somatic mutations can occur due to various factors, such as exposure to environmental mutagens (like radiation or chemicals), errors in DNA replication, and other cellular processes.
    • These mutations can affect the DNA sequence of specific genes, leading to changes in protein production or function.

    DNA Replication: The Copy-Paste Mechanism

    • Genetic Inheritance: Ovum and sperm carry parental genetic blueprints, which combine after fertilization.
    • Cell Division: The single fertilized cell, with 23 chromosomes, multiplies to form the human body’s trillions of cells.
    • DNA Replication Accuracy: Proteins proofread and correct DNA during replication, resulting in an error rate of 0.64-0.78 mutations per billion base pairs per division.

    Impact of Somatic Genetic Mutations

    • Dependent on Timing: Errors occurring after birth but during development are somatic genetic mutations.
    • Driver Mutations: Mutations that confer a fitness advantage to cells can lead to tumor formation and are called driver mutations.
    • Cellular Mosaic: Human body is a mosaic of cells with subtle genomic differences, influenced by somatic genetic variants.
    • Genetic Variants: Genetic variants within functional genome regions can affect protein encoding and regulation.

    Somatic Variants and Physiological Processes

    • Immune Cell Diversity: Immune cells undergo extensive somatic changes to create diverse antibodies recognise pathogens.
    • Recent Knowledge Explosion: Technological advancements in sequencing individual cells have led to an explosion of data and knowledge on somatic variants.
    • Cancer’s Role: Somatic genetic variants play a significant role in cancer development, aiding in early detection, diagnosis, and prognosis.
