About Western Ghats
- The Western Ghats, also known as Sahyadri are a mountain range that covers an area of 140,000 square kilometres parallel to the western coast of the Indian peninsula.
- It traverses the states of Kerala, Tamil Nadu, Karnataka, Goa, Maharashtra and Gujarat.
- It is a UNESCO World Heritage Site and is one of the eight “hottest hot-spots” of biological diversity in the world.
- According to UNESCO, the Western Ghats are older than the Himalayas.
Importance of Western Ghats
- A total of thirty-nine areas in the Western Ghats, including national parks, wildlife sanctuaries and reserve forests, were designated as world heritage sites in 2012 – twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra.
- They influence Indian monsoon weather patterns by intercepting the rain-laden monsoon winds that sweep in from the south-west during late summer.
- The dense forests also contribute to the precipitation of the area by acting as a substrate for condensation of moist rising orographic winds from the sea.
- The northern portion of the narrow coastal plain between the Western Ghats and the Arabian Sea is known as the Konkan, the central portion is called Kanara and the southern portion is called Malabar.
- The Western Ghats form one of the four watersheds of India, feeding the perennial rivers of India.
- The major river systems originating in the Western Ghats are the Godavari, Kaveri, Krishna, Thamiraparani and Tungabhadra rivers.
Facts About Western Ghats for Prelims
- Western Ghats are continuous range of mountains (Gaps exist, but not like the Eastern Ghats)
- Major gaps in the range are the Goa Gap, between the Maharashtra and Karnataka sections, and the Palghat Gap on the Tamil Nadu and Kerala border between the Nilgiri Hills and the Anaimalai Hills.
- The Western Ghats meet the Eastern Ghats at the Nilgiri mountains in north-western Tamil Nadu.
- Evergreen Forests are found here.
- Anaimudi is the highest peak.
- Western Ghats are older than Himalayas.
- Nilgiri Biosphere is the most famous Biosphere reserve in WG.
- Local Names for western ghats are: Sahyadri in Maharashtra, Nilgiri hills in Karnataka and Tamil Nadu, Anaimalai hills and Cardamom hills in Kerala.
Background on Declaration of Western Ghats (WG) region as Ecologically Sensitive Area (ESA)
- In 2010, the Western Ghats Ecology Expert Panel (WGEEP), also known as the Gadgil Commission, recommended that all of the Western Ghats should be declared as the ESA with only limited development allowed in graded zones. It classified the Western Ghats into ESA 1, 2 and 3 of which ESA-1 is a high priority zone where almost all of the developmental activities (mining, thermal power plants, etc) should be restricted. It was criticised for being more environment-friendly and not in tune with the ground realities.
- In 2012, the Kasturirangan Committee sought to balance the development and environment protection in contrast to the system proposed by the Gadgil report – hence, the committee recommended that instead of the total area of Western Ghats, only 37% of the total area to be brought under ESA. Another recommendation of the committee was that NO thermal power projects are to be allowed, hydropower projects are to be allowed only after detailed study and a complete ban on mining, quarrying and sand mining in ESA.
- A draft notification was issued in 2018 mentioning the areas to be notified in the ESA – which is spread over six states of Gujarat, Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu.
- However, the 6 states asked centre to expedite the process to notify the ESAs in the global biodiversity hotspot for clarity – i.e., the states expressed their views as regards activities and extent of area mentioned in the said notification.
- It was decided that state specific issues shall be further deliberated so as to arrive at a consensus on the issue.
What are Eco-Sensitive Zones?
- Eco Sensitive Zones are fragile areas around protected areas declared by the Ministry of Environment, Forest, and Climate Change (MoEFCC).
- They are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
- The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
- Among activities prohibited in the eco-sensitive zone are hydroelectric projects, brick kilns, commercial use of firewood and discharge of untreated effluents in natural water bodies or land areas.
- No new commercial hotels and resorts shall be permitted within 1 km of the boundary of the protected area or up to the extent of the eco-sensitive zone, whichever is nearer, except for small temporary structures for eco-tourism activities.
What does Declaration of Western Ghats as ESA mean?
- In the ESA, all kinds of mining activities, thermal power plants and highly polluting industries would no longer be allowed.
- The existing mines shall be phased out within five years from the issue of final notification or on the expiry of the existing mining lease, whichever is earlier.
- All new ‘Red’ category industries and the expansion of such existing industries shall be banned.
- Other kinds of projects and activities, like operation of hydropower plants, and ‘orange’ category of industries, will be strictly regulated in the ESA.
- New expansion projects of building and construction with built-up area of 20,000 square meters and above shall be prohibited too.

About the Gupta Empire
- The Gupta Empire was an ancient Indian empire which existed from the early 4th century CE to late 6th century CE.
- This period is considered as the Golden Age of India by historians.
- The ruling dynasty of the empire was founded by the king Sri Gupta; the most notable rulers of the dynasty were Chandragupta I, Samudragupta, and Chandragupta II alias Vikramaditya.
- The 5th-century CE Sanskrit poet Kalidasa credits the Guptas with having conquered about twenty-one kingdoms, both in and outside India, including the kingdoms of Parasikas, the Hunas, the Kambojas, tribes located in the west and east Oxus valleys, the Kinnaras, Kiratas, and others.
- Many of the literary sources, such as Mahabharata and Ramayana, were canonized during this period.
- The Gupta period produced scholars such as Kalidasa, Aryabhata, Varahamihira, and Vatsyayana who made great advancements in many academic fields.
About the ASI Discovery in Uttar Pradesh
- Two pillars were excavated on which there is an inscription about Kumaragupta I, the powerful ruler of Gupta dynasty, in ‘sankh lipi’ (conch script or shell script) typical of the 5th century AD.
- The Guptas were the first to build structural temples, distinctly different from the ancient rock-cut temples.
- ASI conducted further excavation and found stairs that led to a structural temple built during the Gupta period. He says the inscription on the stairs possibly reads ‘Sri Mahendraditya’, which was the title of Kumaragupta I.
- The discovery becomes significant since only two other structural temples from the Gupta age have been found so far — Dashavatara Temple (Deogarh) and Bhitargaon Temple (Kanpur Dehat).
What is the Shankhalipi script?
- Shankhalipi or “shell-script” is a term used by scholars to describe ornate spiral characters assumed to be Brahmi derivatives that look like conch shells or shankhas.
- They are found in inscriptions across north-central India and date to between the 4th and 8th centuries.
- Both Shankhalipi and Brahmi are stylised scripts used primarily for names and signatures.
- The inscriptions consist of a small number of characters, suggesting that the shell inscriptions are names or auspicious symbols or a combination of the two.
- The script was discovered in 1836 on a brass trident in Uttarakhand’s Barahat by English scholar James Prinsep, who was the founding editor of the Journal of the Asiatic Society of Bengal.
- Prominent sites with shell inscriptions include the Mundeshwari Temple in Bihar, the Udayagiri Caves in Madhya Pradesh, Mansar in Maharashtra and some of the cave sites of Gujarat and Maharashtra.

About Lake Tanganyika
- Lake Tanganyika is an African Great Lake – the second-oldest freshwater lake in the world.
- Lake Tanganyika is the second-largest by volume, and the second-deepest, in all cases after Lake Baikal in Siberia.
- It is also the world’s longest freshwater lake.
- The lake is shared between four countries—Tanzania, the Democratic Republic of the Congo (DRC), Burundi, and Zambia.
- It drains into the Congo River system and ultimately into the Atlantic Ocean.
About internal displacement in East Africa’s Burundi
- Burundi is among the 20 countries most vulnerable to climate change. It has the most people living along the shores of Lake Tanganyika among the four countries bordering it.
- Lake Tanganyika rose to 776.4 metres (4 meters above average) above sea level in April 2021 due to heavy storms and subsequent flooding and landslides. Several homes and farms were inundated as a consequence.
- During the past two years, persistent heavy rain, followed by floods, landslides and strong winds, raised Lake Tanganyika to dangerous levels.
- Burundi faces the burden of impacts of global emissions and is very poorly adapted to climate change (ranked 171 out of 181 countries in the 2015 Notre Dame Global Adaptation Index).
