FJORD

 
1. Context
The question has been asked in UPSC CSE Mains 2023 General Studies Paper 1 on formation of fjords
 
2. Fjord
 
WHAT IS A FJORD - HOW THE SOGNEFJORD WAS FORMED
A fjord is a deep, narrow and elongated sea or lakedrain, with steep land on three sides. The opening toward the sea is called the mouth of the fjord, and is often shallow. The fjord's inner part is called the sea bottom.
If the geological formation is wider than it is long, it is not a fjord. Then it is a bay or cove
 Fjords are a distinct type of coastal feature and are often characterized by their unique geological and geomorphological characteristics.
A fjord is a long, narrow, deep inlet of the sea that is typically flanked by high cliffs or steep slopes
 
3. Formation of Fjords
The fjords were formed by the giant glacier tongues that through several ice ages have shaped the landscape.
A fjord is thus a U-shaped undersea valley, and on the west coast, this valley is often surrounded by dramatic mountain scenery.
Fjord in its basic meaning "where one fares through", then has the same origin that the word "fare" (travel). The verb "fare" and the noun "ferry", has the same origin

They are commonly found in glaciated regions and have a specific formation process:

  1. Glacial Origins: Fjords are primarily formed through glacial activity. During ice ages or periods of glaciation, glaciers advance and move down valleys, carving out U-shaped troughs or valleys as they flow. These glaciers are typically large and powerful, and they erode the underlying rock and soil as they move.

  2. Glacial Erosion: As glaciers advance, they gouge out these valleys by the sheer force of their movement and the abrasion caused by rocks and debris carried within the ice. The glaciers can reach depths of hundreds of meters.

  3. Glacial Retreat: When the climate begins to warm or other factors cause the glaciers to recede, they start to melt and retreat back up the valleys they carved. As the glacier melts, it leaves behind a deep, narrow, and steep-sided inlet filled with seawater.

  4. Formation of Fjords: These inlets formed by glacial activity are what we now refer to as fjords. Fjords typically have very deep water, sometimes reaching depths of several hundred meters, and their steep sides often extend above the waterline, creating dramatic landscapes.

  5. Unique Features: Fjords are known for their striking beauty and are often surrounded by rugged cliffs or mountains. They can also have waterfalls cascading down the cliffs into the fjord, which adds to their scenic appeal. Fjords are often navigable by ships and boats, making them important natural waterways.

4. Fjords as Picturesque of the World
WHAT IS A FJORD - HOW THE SOGNEFJORD WAS FORMED

Fjords are often considered some of the most picturesque natural landscapes in the world for several reasons:

  1. Dramatic Geological Features: Fjords are characterized by their steep, towering cliffs or mountains that rise abruptly from the water's edge. These striking geological features create a breathtaking visual contrast between the vertical rock faces and the deep, calm waters of the fjord.

  2. Crystal-Clear Waters: Fjords typically have crystal-clear, blue-green waters that can be incredibly inviting and mesmerizing. The clarity of the water allows you to see deep into the fjord, revealing the underwater world and adding to the overall beauty of the landscape

  3. Biodiversity: Fjords are often teeming with biodiversity. They provide important habitats for various marine species, and you can often spot wildlife such as seals, seabirds, and sometimes even whales in and around fjords. The presence of diverse life forms adds to the charm of these landscapes
  4. Waterfalls: Many fjords are adorned with cascading waterfalls that tumble down from the cliffs above into the fjord's waters. These waterfalls create a dynamic and picturesque element, adding movement and sound to the scene

PTERYGOTRIGLA INTERMEDICA 

 
 
1. Context
The scientists of the Zoological Survey of India (ZSI) have discovered a new species of a vibrant orange-coloured deep water marine fish from Digha Mohana in West Bengal.
 
2.Pterygotrigla intermedica
 
New fish species found in Bengal's Digha
  • The new species, commonly known as gurnards or sea-robins, belongs to the family Triglidae. Named Pterygotrigla intermedicait has characters quite similar to species like Pterygotrigla hemisticta 
  • It is the fourth species of Pterygotrigla genus reported in India so far, he said, and there are a total 178 species of the Triglidae family worldwide
  • The specimens of this fish were found to be very distinct from other gurnad species in various aspects such as snout length, shape of the internuchal space and size of the cleithral spine
  • A distinct pectoral-fin with black membranes on the inner surface, white posterior margin and three small white spots basally in fin, each ray creamy white on the new species
  • It had a combination of characters like a long opercular spine and a very short cleithral spine; lateral-line,gill rakers on upper limb and 12–13 on lower limb of first gill arch and  a large black blotch between the 4th and 6th spines of the first dorsal fin
Habitat: They are primarily found in the Indo-Pacific region, including the coasts of India, Indonesia, the Philippines, and northern Australia. They inhabit sandy or muddy seabeds in coastal areas and continental shelves, often at depths ranging from 50 to 400 meters
Feeding Habits: Intermediate sea robins are bottom-dwelling fish that feed on a variety of prey, including small crustaceans, mollusks, and other benthic organisms. They use their pectoral fins to "walk" along the seabed in search of food, using their sensitive barbels to detect prey hidden in the sediment
 
3.Zoological Survey of India (ZSI)
  • The Zoological Survey of India (ZSI) is the premier Indian organization in zoological research and studies to promote the survey, exploration and research of the fauna in the country.
  • It was founded on 1 July 1916 by the Ministry of Environment, Forest and Climate Change of the Government of India.
  • The ZSI has its genesis in the Zoological Section of the Indian Museum, which was established in 1875.
  • By gradually strengthening its staff and expanding its research program, the Survey has grown into a leading institution in zoological research and education.
  • The ZSI is headquartered in Kolkata and has 16 regional centers spread across the country. It has a staff of over 300 scientists and technical personnel.
  • The ZSI's mission is to conduct surveys, exploration and research on the fauna of India, and to disseminate the knowledge gained to the scientific community, government agencies, and the general public

CAPACITY BUILDING INITIATIVE FOR TRANSPARENCY (CBIT)

 
 
1. Context
India and the United Nations have joined hands to introduce a groundbreaking initiative called the “India-UN Capacity Building Initiative,” designed to foster growth and development in the Global South. 
 
2. Capacity-building Initiative for Transparency (CBIT)
  • The Capacity-building Initiative for Transparency (CBIT) is a program established under the United Nations Framework Convention on Climate Change (UNFCCC) to support developing countries in enhancing their capacity to meet their reporting and transparency requirements related to climate action.
  • CBIT was created as part of the Paris Agreement, which was adopted in 2015 and aims to combat climate change by limiting global warming to well below 2 degrees Celsius above pre-industrial levels.
  • CBIT focuses on helping developing countries strengthen their institutional and technical capabilities to accurately measure, report, and verify their greenhouse gas emissions and the progress they are making in implementing climate mitigation and adaptation activities. This transparency is crucial for tracking global progress toward achieving the climate goals set out in the Paris Agreement.

3. COP 21

COP 21 decided that the aim of CBIT is to:

  1. Strengthen national institutions for transparency-related activities in line with national priorities;
  2. Provide relevant tools, training and assistance for meeting the provisions stipulated in Article 13 of the Agreement; and
  3. Assist in the improvement of transparency over time.
4. Transparency within the Paris Agreement

Transparency is a fundamental principle within the Paris Agreement, which was adopted in 2015 as a landmark international treaty to address climate change. The Agreement recognizes the importance of transparency in several key aspects:

  1. Transparency of Action: Under the Paris Agreement, countries that are Parties to the Agreement (referred to as Parties) are required to regularly communicate their efforts to mitigate greenhouse gas emissions (referred to as "nationally determined contributions" or NDCs) and adapt to the impacts of climate change. This includes providing information on their emission reduction targets, policies, and measures taken to achieve these targets. This transparency enables other Parties and stakeholders to assess the adequacy and effectiveness of a country's climate actions.

  2. Transparency of Support: Developed countries, often referred to as Annex II Parties, have an obligation to provide financial resources, technology transfer, and capacity-building support to developing countries to help them cope with climate change. Transparency in financial flows and support is crucial to ensure that these commitments are being met and that the support is reaching those who need it most.

  3. Transparency of Information Sharing: The Paris Agreement establishes a framework for the transparent sharing of information, data, and best practices related to climate change. This information sharing helps Parties learn from each other's experiences and promote cooperation and mutual assistance in tackling climate change.

  4. Transparency Framework: The Agreement includes provisions for the development of a "enhanced transparency framework." This framework sets out the rules and procedures for reporting and reviewing the climate-related information that Parties provide. It ensures that the information exchanged is consistent, comparable, and reliable. The enhanced transparency framework is designed to be more robust and comprehensive than the transparency arrangements under the previous Kyoto Protocol.

  5. Review and Accountability: The Paris Agreement includes a process for the regular review of Parties' progress in implementing their climate actions. This process, often referred to as the "global stocktake," is conducted every five years to assess collective progress toward the Agreement's goals. Transparency is crucial in this context, as it allows for an objective assessment of each Party's efforts.

5. Global Environment Facility (GEF)
The GEF, or Global Environment Facility, is a financial mechanism that provides grants and funding to support projects and initiatives aimed at addressing global environmental issues. The GEF was established in 1991 and operates as an independent financial organization that serves as a catalyst for international cooperation on environmental problems
 
5.1.Role of the GEF in the CBIT as per the Paris Agreement
The Global Environment Facility (GEF) plays a significant role in supporting the implementation of the Capacity-building Initiative for Transparency (CBIT) as outlined in the Paris Agreement.
CBIT is a crucial component of the Paris Agreement's efforts to enhance transparency, accountability, and capacity building in developing countries in their pursuit of climate action

Here's how the GEF contributes to CBIT:

  1. Financial Support: One of the primary roles of the GEF in the CBIT is to provide financial resources to support capacity-building activities related to transparency. This includes funding for training programs, workshops, technical assistance, and the development of necessary infrastructure and systems to improve a country's ability to measure, report, and verify its greenhouse gas emissions and climate actions accurately.

  2. Project Implementation: The GEF, through its implementing agencies such as the United Nations Development Programme (UNDP) and the United Nations Environment Programme (UNEP), assists developing countries in designing and implementing CBIT projects. These projects aim to enhance national capacity for transparency in line with the Paris Agreement's requirements.

  3. Technical Assistance: The GEF supports countries in accessing technical expertise and knowledge to strengthen their institutional and technical capabilities. This includes assistance in developing or improving national greenhouse gas inventories, data management systems, and the legal and regulatory frameworks needed for transparency.

  4. Promotion of Best Practices: The GEF helps disseminate best practices and lessons learned from CBIT projects across different countries. This knowledge sharing is crucial for countries to learn from each other's experiences and to adopt effective approaches to transparency-related activities.

  5. Facilitating Collaboration: The GEF facilitates collaboration among various stakeholders, including governments, non-governmental organizations (NGOs), and international agencies, to ensure a coordinated and integrated approach to CBIT implementation. Collaboration helps avoid duplication of efforts and maximizes the impact of capacity-building activities.

  6. Reporting and Accountability: As part of its commitment to transparency and accountability, the GEF reports on its financial contributions to CBIT and the outcomes achieved through its support. This reporting helps donors, countries, and other stakeholders track progress and assess the effectiveness of CBIT projects.

  7. Integration with Climate Finance: The GEF's support for CBIT aligns with broader climate finance efforts. It ensures that capacity-building for transparency is integrated into the larger framework of climate finance, which includes both public and private sources of funding.

SOUTH CHINA SEA

1. Context

Recently, The Philippines accused China’s coast guard of installing a “floating barrier” in a disputed area of the South China Sea, saying it prevented Filipinos from entering and fishing in the area.

2. China's South China Sea Escalation

  • Amid the global pandemic, China is intensifying its presence in the South China Sea, particularly focusing on the disputed Spratly Islands and Paracel Islands.
  • This move has raised concerns among neighbouring countries, such as Vietnam and the Philippines, who also claim sovereignty over these territories.
  • China has unilaterally renamed 80 islands and geographical features in the South China Sea, a controversial action that has drawn criticism from neighbouring nations.
  • This renaming effort exacerbates the ongoing territorial dispute and has the potential to strain diplomatic relations in the Asia-Pacific region.
  • The Spratly Islands dispute involves China, Taiwan, Vietnam, the Philippines, and Malaysia, all vying for control over this archipelago and its surrounding features.
  • Although these islands are largely uninhabited, they are believed to harbour significant untapped natural resources.
  • However, due to the dispute, exploration and resource assessment efforts remain limited.

3. Historical Background

  • The discovery of oil near the Palawan coast in the 1970s further fueled territorial claims, even though some reports suggest limited oil and gas reserves in the region.
  • This historical context underscores the complexity of the Spratly Islands dispute.
  • The Paracel Islands dispute is equally complex, with China and Vietnam both laying historical claims to this archipelago.
  • Historical texts from various periods, including colonial-era records, have been cited to support these conflicting claims.
  • Tensions escalated in 1974 when China took control of the islands, sparking a prolonged dispute involving Vietnam and, later, Taiwan.
Image Source: Forbes

4. Contemporary Developments

  • Since 2012, China, Taiwan, and Vietnam have pursued various strategies to bolster their territorial claims, including constructing government buildings, promoting tourism, reclaiming land, and expanding military presence on these islands.
  • China's recent establishment of new administrative districts in both the Spratly and Paracel Islands prompted the Chinese government to rename numerous geographical features.
  • This move is reminiscent of a similar initiative in 1983 when China renamed 287 features in the disputed region.
  • China's increased military activity and the creation of artificial islands for military and economic purposes in the South China Sea have raised concerns among neighbouring countries and Western powers.
  • Recent incidents, such as the sinking of a Vietnamese fishing trawler near the Paracel Islands and the construction of Chinese research stations on disputed Philippine territory, have further inflamed tensions.

5. Conclusion

  • The South China Sea remains a highly volatile region, with the potential for further diplomatic tensions and military escalations.
  • The ongoing territorial disputes, fueled by historical claims and concerns over natural resources, pose a significant challenge to stability in the Asia-Pacific region and require careful diplomatic efforts to find peaceful resolutions.

LONG PERIOD AVERAGE (LPA)

 
1. Context
The monsoon has been erratic, arriving a week late in June that recorded overall 10.1% rainfall deficiency. But the 12.6% above-normal rain in July helped spur plantings of most kharif crops..

Rainfall in the four-month June-September southwest monsoon season was in the normal range in 2019, 2020, and 2021 as well

2. About Long Period Average (LPA)

  • The IMD predicts a “normal”, “below normal”, or “above normal” monsoon in relation to a benchmark “long period average” (LPA)
  • According to the IMD, the “LPA of rainfall is the rainfall recorded over a particular region for a given interval (like month or season) average over a long period like 30 years, 50 years, etc”
  • The IMD’s prediction of a normal monsoon on Thursday was based on the LPA of the 1971-2020 period, during which India received 87 cm of rain for the entire country on average
  • The IMD has in the past calculated the LPA at 88 cm for the 1961-2010 period, and at 89 cm for the period 1951-2000
  • While this quantitative benchmark refers to the average rainfall recorded from June to September for the entire country, the amount of rain that falls every year varies from region to region and from month to month
  • Therefore, along with the countrywide figure, the IMD also maintains LPAs for every meteorological region of the country  this number ranges from around 61 cm for the drier Northwest India to more than 143 cm for the wetter East and Northeast India
  • LPA of the southwest monsoon rainfall over Kerala: 556 mm, 659 mm, 427 mm and 252 mm for the months of June, July, August, and September respectively
  • Broken down monthwise for the entire country, the LPA figures for the season are 16.36 cm for June, 28.92 cm for July, 26.13 cm for August, and 17.34 cm for September

3. Need of LPA

  • The IMD records rainfall data at more than 2,400 locations and 3,500 rain-gauge stations
  • Because annual rainfall can vary greatly not just from region to region and from month to month, but also from year to year within a particular region or month, an LPA is needed to smooth out trends so that a reasonably accurate prediction can be made
  • A 50-year LPA covers for large variations in either direction caused by freak years of unusually high or low rainfall (as a result of events such as El Nino or La Nina)
  • As well as for the periodic drought years and the increasingly common extreme weather events caused by climate change

4.IMD Calculations

Quantitatively, the monsoon seasonal (June to September) rainfall is likely to be 99% of the LPA with a model error of ± 5%. The LPA of the season rainfall over the country as a whole for the period 1971-2020 is 87 cm

The IMD maintains five rainfall distribution categories on an all-India scale. These are:

  • Normal or near normal, when the percentage departure of actual rainfall is +/-10% of LPA, that is, between 96-104% of LPA
  • Below normal, when departure of actual rainfall is less than 10% of LPA, that is 90-96% of LPA
  • Above normal, when actual rainfall is 104-110% of LPA
  • Deficient, when departure of actual rainfall is less than 90% of LPA
  • Excess, when the departure of actual rainfall is more than 110% of LPA
 
5. About India Meteorological Department
  • The beginnings of meteorology in India can be traced to ancient times. Early philosophical writings of the 3000 B.C. era, such as the Upanishadas, contain serious discussion about the processes of cloud formation and rain and the seasonal cycles caused by the movement of earth round the sun
  • Varahamihira's classical work, the Brihatsamhita, written around 500 A.D., provides a clear evidence that a deep knowledge of atmospheric processes existed even in those times
  • It was understood that rains come from the sun (Adityat Jayate Vrishti) and that good rainfall in the rainy season was the key to bountiful agriculture and food for the people
  • Kautilya's Arthashastra contains records of scientific measurements of rainfall and its application to the country's revenue and relief work. Kalidasa in his epic, 'Meghdoot', written around the seventh century, even mentions the date of onset of the monsoon over central India and traces the path of the monsoon clouds
  • Meteorology, as we perceive it now, may be said to have had its firm scientific foundation in the 17th century after the invention of the thermometer and the barometer and the formulation of laws governing the behaviour of atmospheric gases
  • It was in 1636 that Halley, a British scientist, published his treatise on the Indian summer monsoon, which he attributed to a seasonal reversal of winds due to the differential heating of the Asian land mass and the Indian Ocean
  • India is fortunate to have some of the oldest meteorological observatories of the world. The British East India Company established several such stations, for example, those at Calcutta in 1785 and Madras (now Chennai) in 1796 for studying the weather and climate of India
  • The Asiatic Society of Bengal founded in 1784 at Calcutta, and in 1804 at Bombay (now Mumbai), promoted scientific studies in meteorology in India
  • A disastrous tropical cyclone struck Calcutta in 1864 and this was followed by failures of the monsoon rains in 1866 and 1871
  • In the year 1875, the Government of India established the India Meteorological Department, bringing all meteorological work in the country under a central authority
  • The first Director General of Observatories was Sir John Eliot who was appointed in May 1889 at Calcutta headquarters
  • The headquarters of IMD were later shifted to Shimla, then to Poona (now Pune) and finally to New Delhi
  • From a modest beginning in 1875, IMD has progressively expanded its infrastructure for meteorological observations, communications, forecasting and weather services and it has achieved a parallel scientific growth
  • IMD has always used contemporary technology. In the telegraph age, it made extensive use of weather telegrams for collecting observational data and sending warnings
  • Later IMD became the first organisation in India to have a message-switching computer for supporting its global data exchange.
  • One of the first few electronic computers introduced in the country was provided to IMD for scientific applications in meteorology
  • India was the first developing country in the world to have its own geostationary satellite, INSAT, for continuous weather monitoring of this part of the globe and particularly for cyclone warning
  • IMD has continuously ventured into new areas of application and service and steadily built upon its infrastructure in its history of 140 years
  • It has simultaneously nurtured the growth of meteorology and atmospheric science in India. Today, meteorology in India is poised at the threshold of an exciting future
