Andaman & Nicobar Islands home to tenth of India’s fauna species: ZSI

Andaman & Nicobar Islands are to home to tenth of India’s fauna species and hosts 1,067 endemic faunal species found nowhere else. It was revealed by Zoological Survey of India (ZSI) publication titled Faunal Diversity of Biogeographic Zones: Islands of India. This publication for the first time has come up with database of all faunal species found on the island. It has database of species found in particular category of animals and also highlights most vulnerable among them.

Highlights of ZSI publication

Total area of A&N Islands, which comprises of 572 islands, islets and rocky outcrops, is about 8,249 sq. km has around total 11,009 species. It comprises only 0.25% of India’s geographical area but is home to more than 10% of country’s fauna species. Thus, presence of such large number of species in such small area makes A&I Islands one of the richest ecosystems and biodiversity hot spots in India. Tourism, illegal construction and mining are posing threat to the islands’ biodiversity, which is already vulnerable to volatile climatic factors. Some of the species in A&N Islands are restricted to very small area and thus more vulnerable to any anthropogenic threat.

Marine fauna: Of the ten species of marine fauna found on islands, dugong/sea cow and Indo-Pacific humpback dolphin are both classified as Vulnerable under IUCN Red List of Threatened Species.

Terrestrial mammalian species: 46 terrestrial mammalian species are found. 3 species have been categorised as Critically Endangered —Jenkin’s shrew (C. jenkinsi), Andaman shrew (Crocidura andamanensis) and Nicobar shrew (C. nicobarica). Five species are listed as Endangered, 9 species as Vulnerable, and 1 species as Near Threatened by IUCN.

Birds: Endemism is quite high in A&N islands, with 36 among 344 species of birds found only on the islands. Many of these bird species are placed in IUCN Red List of threatened species and also under the Wildlife Protection Act (WPA).

Marine diversity: Eight species of amphibians and 23 species of reptiles are endemic to the islands. They are at high risk of being threatened.

Marine faunal diversity: It includes coral reefs and its associated fauna. In all, 555 species of scleractinian corals (hard or stony corals) are found in the island ecosystem, all which are placed under Schedule I of the WPA.

Zoological Survey of India (ZSI)

It is India’s apex organization on animal taxonomy. Its objective is to promote survey, exploration, research and documentation on various aspects of animal taxonomy in Indian subcontinent. It also seeks advancement of knowledge on animal taxonomy. It was established in 1916 and headquartered in Kolkata. It has been declared as designated repository for National Zoological Collection as per section 39 of the National Biodiversity Act, 2002.

CCEA approves Atmosphere & Climate Research-Modelling Observing Systems & Services (ACROSS) scheme

Prime Minister Narendra Modi chaired Cabinet Committee of Economic Affairs (CCEA) has approved continuation of nine sub-schemes of umbrella scheme “Atmosphere & Climate Research-Modelling Observing Systems & Services (ACROSS)” during 2017-2020. The scheme aims at improving skill of weather and climate forecast through sustained observations, intensive Research & Development.

ACROSS Scheme

The scheme pertains to the atmospheric science programs of the Ministry of Earth Sciences (MoES). Its objective is to provide reliable weather and climate forecast for betterment of society. It also aims at improving skill of weather and climate forecast through sustained observations, intensive R & D. It consists of nine sub-programmes which are multi-disciplinary and multi institutional in nature and will be implemented in integrated manner. It seeks to addresses different aspects of weather and climate services, which includes warnings for cyclone, storm surges, heat waves, thunderstorms etc. Each of these aspects is incorporated as nine sub-schemes under umbrella scheme ACROSS and is implemented in integrated manners.

Benefits of Scheme

It will provide improved weather, climate and ocean forecast and services, thereby ensuring transfer of commensurate benefits to the various services. It will also provide a sizable number of scientific and technical staff along with requisite administrative support, thereby generating employment. It will generate employment opportunities to many people as large number of agencies like the Krishi Vigyana Kendras of ICAR, Universities and local municipalities are roped to ensure last-mile connectivity of the weather based services to the end –user.

Background

Union Ministry of Earth Sciences has mandate to carry out R&D activities to develop and improve capability to forecast weather, climate and natural hazard related phenomena. Towards this direction, it has undertaken several initiatives to formulate specific schemes like weather and climate modelling, monsoon-research, climate change science & climate services etc. These schemes involve multi-institutes wherein each unit has designated role for accomplishing aforesaid tasks. As result, all these schemes with specific objectives and budget are implemented in an integrated manner and are put together under the umbrella scheme “ACROSS”.
