China’s New Project in Sri Lanka

Why in News

Recently, a Chinese company has won a contract to set up hybrid wind and solar energy projects on three Sri Lankan islands off the northern Jaffna peninsula 45 km from Rameswaram in Tamil Nadu.

• Asian Development Bank (ADB) will fund the project, which will come up on Delft, Nainativu and Analativu, three islands in the Palk Strait off Jaffna peninsula.

Key Points

• About the Islands:
  
  • Delft, the largest of the three islands, is the closest to Rameswaram, Tamil Nadu, which lies to the island’s south west.
    
    • Between the two is Kachchativu, the tiny island that India ceded to Sri Lanka in 1974.
    • The waters around these islands are an area of contest and rivalry between Tamil Nadu and Jaffna fishers.
    • The matter has been on the bilateral agenda for decades.
    • India and Sri Lanka agreed to set up a Joint Working Group (JWG) on Fisheries in 2016 between the Ministry of Agriculture and Farmers Welfare of India and Ministry of Fisheries and Aquatic Resources Development of Sri Lanka as the mechanism to help find a permanent solution to the fishermen issue.
• Sri Lanka’s Stand:
  
  • It cannot be blamed for this decision, because the project is backed by the ADB, which has its “own procurement guidelines that should be followed by the borrower”.
• India’s Concern:
  
  • The project site’s proximity to the Indian coastline.
    
    • Chinese presence in the vicinity is not welcomed especially when India already has many unresolved issues with China.
    • This deal came at a time when India’s confrontation with China in Ladakh is yet to be resolved.
  • Recently, the Sri Lankan government cancelled the contract with India and Japan for the Eastern Container Terminal (ECT).
    
    • The tripartite agreement, signed by India, Sri Lanka and Japan, proposed to develop the ECT, which is located at the newly expanded southern part of the Colombo Port.
    • For India, the ECT deal was important as around 70% of transhipment that takes place through it is India-linked. The ECT is also considered more strategic than any other in Colombo Port.
• India’s Stand:
  
  • India had lodged a strong protest with the Sri Lankan government on the contract to the Chinese company.
    
    • In 2018, India voiced concern over China’s USD 300 million housing project for war-affected areas, accusing the Resettlement Ministry [of the former government] of holding an “opaque” bidding process.
      
      • The project was eventually dropped.

China’s Rising Influence in South Asia

• Recent Initiative:
  
  • In January 2021 China held its third multilateral dialogue virtually with countries from South Asia to take forward closer cooperation on fighting Covid-19 and coordinating their economic agendas, reflecting a new approach in Beijing’s outreach to the region.
• Other Initiatives:
  
  • According to the American Enterprise Institute’s China Global Investment Tracker, China has committed around 100 billion USD in the economies of Afghanistan, Bangladesh, the Maldives, Pakistan, Nepal and Sri Lanka.
    
    • China is now the largest overseas investor in the Maldives, Pakistan, and Sri Lanka.
• Concerns for India:
  
  • Security Concerns:
    
    • Growing cooperation between Pakistan and China.
    • Increasing nexus between Nepal and China.
    • Acceptance to China-Pakistan Economic Corridor by south asian countries.
  • Leadership Roles in South Asia:
    
    • It shows increasing chinese presence in south asia and its acceptance by the countries as a torch bearer for the region which India wants for itself.
  • Economic Concerns:
    
    • Over the past decade, China has replaced India as the major trading partner of several South Asian countries.
    • For instance, the share of India’s trade with Maldives was 3.4 times that of China’s in 2008. But by 2018, China’s total trade with Maldives slightly exceeded that of India.
  • China’s trade with Bangladesh is now about twice that of India. China’s trade with Nepal and Sri Lanka still lags India’s trade with those countries but the gap has shrunk.

Way Forward

• India does not have the economic capacity as China. Thus it should cooperate with China for the development of these countries such that fruits of development collectively reach South Asia. Further India should invest in countries where China falls short and maintain its good will in South Asia and prevent these nations from slipping off from India’s Influence.
• Along with strongly condemning the plans for extension of the China-Pakistan Economic Corridor, India also needs to focus more on its traditional and cultural ties to improve relations with its neighbours.

Kuruba Community: Karnataka

Why in News

A massive rally was organised by the Kuruba community to urge the state government of Karnataka to recommend the Centre inclusion of the community in the Scheduled Tribe (ST) list.

Key Points

• Background:
  
  • From Independence, the community enjoyed the ST status. In 1977, Justice LG Havanur, who headed the backward class commission, moved the Kurubas to the ‘most backward classes’ category from ST list.
  • However, the Commission brought in an area restriction stating that those living in Bidar, Yadgir, Kalaburagi and Madikeri with Kuruba synonyms can continue to avail the ST benefits.
• About Kurubas:
  
  • The Kurubas of Karnataka are a traditional sheep rearing community.
  • Presently, the Kurubas constitute 9.3% of the state’s population and come under the backward classes category.
  • Kurubas are the fourth largest caste in Karnataka after the Lingayats, Vokkaligas and Muslims.
  • Kurubas in other states are known by different names – as Dhangars in Maharashtra, Rabaris or Raikas in Gujarat, Dewasis in Rajasthan and Gadarias in Haryana.
• Related Developments:
  
  • Demands by Lingayat Community: Three years earlier, the Lingayat community demanded a separate minority religion tag in Karnataka.
    
    • The Lingayat sub-sect Panchamasali has also demanded its inclusion in the 2A category of backward classes - which currently provides 15% reservations to backward castes.
  • Justice HN Nagamohan Das Commission:
    
    • The Justice HN Nagamohan Das Commission was constituted to look into increasing the existing reservation for SCs from 15% to 17% and for the STs from 3% to 7% by not exceeding the overall 50% reservation quota as mandated by the Supreme Court's order of 1992.
      
      • If Kurubas are to be declared ST as per their demand, the quota for STs will have to be proportionally increased.
  • Challenge:
    
    • The larger issue is that the State has already hit the apex court set 50% cap on reservation and any hike poses a challenge.
• Present Reservation Quota in Karnataka:
  
  • Adhering to the Supreme Court’s 1992 order, Karnataka has capped the reservation to 50% where 32% has been earmarked for backward classes, including Muslims, Christians and Jains, 15% for SCs and 3% for STs.
  • This reservation quota has been further pared into categories: Category 1 (4%), Category 2A (15%), Category 2B (4%), Category 3A (4%), Category 3B (5%), SC (15%) and ST (3%).

Mental Health and Men

Why in News

As per the data of the Ministry of Social Justice and Empowerment, 70% of callers to the ‘Kiran Helpline’, launched in September 2020, were men. Most of the calls have been from young adults.

• The 24/7 toll-free helpline ‘Kiran’ provides support to people facing anxiety, stress, depression, suicidal thoughts and other mental health concerns.

Key Points

• Data Analysis:
  
  • Gender & Mental Health: Out of the 13,550 new calls received, 70.5% were from males and 29.5% from females.
  • Vulnerable Age Group: The majority of callers (75.5%) were in the age group of 15 to 40 years, while 18.1% in the 41 to 60 age group.
  • Major Issues: Majorly the challenges faced by the callers were related to anxiety and depression; while few others included pandemic-related challenges, suicidal tendency, substance abuse and others miscellaneous.
• Issues Related to Male Mental Health:
  
  • Traditional Gender Roles: Societal expectations and traditional gender roles play an important role in why men are less likely to discuss or seek help for their mental health problems.
  • Ignoring Warning Signs: For men, the warning signs of mental disorders include irritability, trouble focusing, tiredness or listlessness, aches and pains, alcohol or drug abuse and more.
  • Lack of Proper Attention: Research on men’s health issues has been given relatively low priority. Due to lack of funding and proper attention, the situation becomes more serious.
  • Increase in Number of Suicides: In 2018, around 250 Indian men took their own lives per day - more than twice the number of women.

Mental Health

• About:
  
  • According to the WHO, mental health is ‘a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community.’
  • Like Physical health, Mental health is also important at every stage of life, from childhood and adolescence through adulthood.
• Challenges:
  
  • High Public Health Burden: An estimated 150 million people across India are in need of mental health care interventions, according to India’s latest National Mental Health Survey 2015-16.
  • Lack of Resources: Low proportion of the mental health workforce in India (per 100,000 population) include psychiatrists (0.3), nurses (0.12), psychologists (0.07) and social workers (0.07).
    
    • Low financial resource allocation of just over a percent of GDP on healthcare has created impediments in public access to affordable mental healthcare.
  • Other Challenges: Poor awareness about the symptoms of mental illness, social stigma and abandonment of mentally ill, especially old and destitute, leads to social isolation and reluctance on part of family members to seek treatment for the patient.
    
    • This has resulted in a massive treatment gap, which further worsens the present mental illness of a person.
• Steps Taken by the Government:
  
  • National Mental Health Program (NMHP):
    
    • To address the huge burden of mental disorders and shortage of qualified professionals in the field of mental health, the government has been implementing the National Mental Health Program (NMHP) since 1982.
    • The Program was re-strategized in 2003 to include two schemes, viz. Modernization of State Mental Hospitals and Up-gradation of Psychiatric Wings of Medical Colleges/General Hospitals.
  • Mental HealthCare Act 2017:
    
    • It guarantees every affected person access to mental healthcare and treatment from services run or funded by the government.
    • It has significantly reduced the scope for the use of Section 309 IPC and made the attempt to commit suicide punishable only as an exception.
      
      • Section 115(1) of the MHCA states: “Notwithstanding anything contained in section 309 of the Indian Penal Code any person who attempts to commit suicide shall be presumed, unless proved otherwise, to have severe stress and shall not be tried and punished under the said Code.”

Way Forward

• Many researches have emphasized the importance of ‘disrupting how men traditionally think about depression and suicide by breaking down the stigma that surrounds these topics’ through nationwide campaigns.
• Originating a dialogue, sustaining that dialogue, challenging outdated social mores, and giving a voice to the voiceless without fear of exclusion and mockery is what needs to be undertaken to ensure that all people’s mental health is taken seriously and addressed in a manner that is dignified and respectful.
• Modern techniques, such as web-based interventions and electronic health (e-health) tools, can also be developed and utilized to reach out to people who might not otherwise seek help.

Mapping Seismic Hazard of Eastern Himalaya

Why in News

Recently, scientists have found the first geological evidence of an earthquake on the border of Assam and Arunachal Pradesh, documented as the Sadiya earthquake in history. This finding could contribute to a seismic hazard map of the eastern Himalaya, which can facilitate construction and planning in the region.

• This site is near the Tuting-Tidding Suture Zone- a major part of the Eastern Himalaya, where the Himalaya takes a sharp southward bend and connects with the Indo-Burma Range.

Key Points

• About:
  
  • Scientists from Wadia Institute of Himalayan Geology (WIHG) carried out a mega trench excavation at Himebasti village, Arunachal Pradesh where the most recent event records the imprints of the 1697 Sadiya earthquake and analysed it with modern geological techniques.
    
    • WIHG is an autonomous institute under the Department of Science and Technology (DST), Government of India.
  • Scientists found large tree trunks embedded in the youngest flood deposits at the exit of the Subansiri River (Sadiya town is located roughly 145 km southeast of Subansiri river), suggesting the post-seismic aggradation of the river following an array of aftershocks till six months.
    
    • Aggradation is the term used in geology for the increase in land elevation due to deposition of sediment.
    • Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock.
• Significance:
  
  • Studying the past earthquakes help to determine the seismic potential of the region. This helps in mapping the earthquake hazard of the region and enables syncing the development activities accordingly.
  • Arunachal Pradesh, being near the Indo-China Border, and sometimes centre of dispute regarding its ownership, is strategically important.
    
    • A number of development initiatives like constructing roads, bridges and hydropower projects are being undertaken, therefore there is an urgent need for understanding the pattern of seismicity in this region.
• Seismic Hazard Map of India:
  
  • India is one of the highly earthquake affected countries because of the presence of tectonically active young fold mountains, Himalayas.
  • India has been divided into four seismic zones (II, III, IV, and V) based on scientific inputs relating to seismicity, earthquakes occurred in the past and tectonic setup of the region.
    
    • Previously, earthquake zones were divided into five zones with respect to the severity of the earthquakes but the Bureau of Indian Standards (BIS) grouped the country into four seismic zones by unifying the first two zones.
    • BIS is the official agency for publishing the seismic hazard maps and codes.

• Seismic Zone II:
  
  • Area with minor damage earthquakes corresponding to intensities V to VI of MM scale (MM-Modified Mercalli Intensity scale).
• Seismic Zone III:
  
  • Moderate damage corresponding to intensity VII of MM scale.
• Seismic Zone IV:
  
  • Major damage corresponding to intensity VII and higher of MM scale.
• Seismic Zone V:
  
  • Area determined by pro seismically of certain major fault systems and is seismically the most active region.
  • Earthquake zone V is the most vulnerable to earthquakes, where historically some of the country’s most powerful shocks have occurred.
  • Earthquakes with magnitudes in excess of 7.0 have occured in these areas, and have had intensities higher than IX.
• Seismic Waves, Richter Scale and Mercalli scale:
  
  • Seismic waves are the vibrations from earthquakes that travel through the Earth and are recorded on instruments called seismographs.
    
    • Seismographs record a zigzag trace that shows the varying amplitude of ground oscillations beneath the instrument.
  • The earthquake events are scaled either according to the magnitude or intensity of the shock.
    
    • The magnitude scale is known as the Richter scale. The magnitude relates to the energy released during the earthquake which is expressed in absolute numbers, 0-10.
    • The intensity scale or Mercalli scale takes into account the visible damage caused by the event. The range of intensity scale is from 1-12.

Hunter Syndrome: MPS II

Why in News

Two brothers suffering from Mucopolysaccharidosis II or MPS II (Hunter Syndrome, Attenuated Type) have approached the Delhi High Court seeking direction to the Centre and AIIMS to provide them free treatment.

• MPS II is a rare disease that is passed on in families.

Key Points

• About: MPS II mostly affects boys and their bodies cannot break down a kind of sugar that builds bones, skin, tendons and other tissues.
• Cause: It is caused by changes (mutations) of the IDS gene that regulates the production of the iduronate 2-sulfatase (I2S) enzyme.
  
  • This enzyme is needed to break-down complex sugars, known as glycosaminoglycans (GAGs), produced in the body.
• Impact: Lack of I2S enzyme activity leads to the accumulation of GAGs within cells, specifically inside the lysosomes.
  
  • Lysosomes are compartments in the cell that digest and recycle different types of molecules.
  • Conditions that cause molecules to build up inside the lysosomes, including MPS II, are called lysosomal storage disorders.
  • The accumulation of GAGs increases the size of the lysosomes, which is why many tissues and organs are enlarged in this disorder.
• Symptoms: It is characterized by distinctive facial features, a large head, enlargement of the liver and spleen (hepatosplenomegaly), hearing loss, etc.
• Inheritance:
  
  • MPS II is inherited in an X-linked recessive pattern, which means that this condition occurs almost exclusively in males. Females are generally unaffected carriers of this condition.
  • In a family with more than one affected individual, the mother of the affected males must be a carrier. When a carrier female has a child, there is a 25% (1 in 4) chance that she will have an affected son.
