    The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an independent intergovernmental body, established by member States in 2012. The objective of IPBES is to strengthen the science-policy interface for biodiversity and ecosystem services for the conservation and sustainable use of biodiversity, long-term human well-being and sustainable development.

    IPBES currently has over 130 member States. A large number of NGOs, organizations, conventions and civil society groupings also participate in the formal IPBES process as observers, with several thousand individual stakeholders, ranging from scientific experts to representatives of academic and research institutions, local communities and the private sector, contributing to and benefiting from our work.

    The work of IPBES can be broadly grouped into four complementary areas:

    • Assessments: On specific themes (e.g. “Pollinators, Pollination and Food Production”); methodological issues (e.g. “Scenarios and Modelling); and at both the regional and global levels (e.g. “Global Assessment of Biodiversity and Ecosystem Services”).

    • Policy Support: Identifying policy-relevant tools and methodologies, facilitating their use, and catalyzing their further development.

    • Building Capacity & Knowledge: Identifying and meeting the priority capacity, knowledge and data needs of our member States, experts and stakeholders.

    • Communications & Outreach: Ensuring the widest reach and impact of our work.

    Lakshadweep is an archipelago of 36 islands, scattered over approximately 78,000 square km of the Arabian Sea, 200-440 kms off the south-western coast of India, with population of approximately 65,000.

    The islands are located between Africa and southwestern part of India.

    In the Arabian Sea, there are three types of islands.

    Amindivi Islands (consisting of six main islands of Amini, Keltan, Chetlat, Kadmat, Bitra and Perumul Par). [don’t have to remember all these names]

    Laccadive Islands (consisting of five major islands of Androth, Kalpeni, Kavaratti, Pitti and Suheli Par) and

    Minicoy Island.

    At present these islands are collectively known as Lakshadweep.

    The Lakshadweep Islands are a group of 25 small islands.

    They are widely scattered about 200-500 km south-west of the Kerala coast.

    Amendivi Islands are the northern most while the Minicoy island is the southernmost.

    All are tiny islands of coral origin {Atoll} and are

    surrounded by fringing reefs.

    The largest and the most advanced is Lakshadweep Islandsthe Minicoy island with an area of 4.53 sq km.

    Most of the islands have low elevation and do not rise more than five metre above sea level (Extremely Vulnerable to sea level change).

    Their topography is flat and relief features such as hills, streams, valleys, etc. are absent.
