    Question

    Which Indian state has announced a plan to build a 'Great Green Wall' by 2030 to protect its coastline?

    A.

    Tamil Nadu

    B.

    West Bengal

    C.

    Odisha

    D.

    Andhra Pradesh

    Correct option is D

    The correct answer is (d) Andhra Pradesh
    Explanation:
    • The Andhra Pradesh government officially launched the "Great Green Wall of Andhra Pradesh" initiative in late 2025/early 2026.
    • The project aims to create a 5-km-wide living ecological shield along the state's entire 1,053-km coastline.
    • It is a strategic response to protect over 3 million coastal residents from the devastating effects of cyclones and sea erosion.
    • The initiative has set a strict target for completion by the year 2030, aligning with global climate goals.
    • The project is being spearheaded by the state's Environment and Forest Department, with significant leadership from the Deputy CM.

    Information Booster:
    • The project is inspired by the African Union's Great Green Wall and India’s Aravalli Green Wall Project, focusing on ecological restoration.
    • It utilizes a multi-layered buffer zone consisting of mangroves, casuarina, palmyra trees, and the restoration of natural sand dunes.
    • Funding and implementation are supported through a convergence of schemes like MGNREGS, CAMPA (Compensatory Afforestation Fund), and the Green Credit Program.

    Additional Knowledge:
    Tamil Nadu (Option a)
    • The state implements the "TN-SHORE" (Tamil Nadu Coastal Restoration Mission) with World Bank assistance.
    • While it focuses on coastal resilience and mangrove restoration, it does not use the "Great Green Wall" branding for its coastline.

    West Bengal (Option b)
    • West Bengal has a "Green Wall" project, but it is an 800-km inland belt along the Jharkhand border.
    • Its primary goal is to combat air pollution and desertification rather than coastal protection.

    Odisha (Option c)
    • Odisha has a robust Climate Change Action Plan (2021–2030) and a "Mega Mangrove Drive" to plant millions of trees.
    • However, it has not officially branded its state-wide coastal mission as the "Great Green Wall", which is specific to the Andhra Pradesh announcement.
