Sundarbans

For Prelims: Sundarbans, Estuarine crocodile, Water monitor lizard, Gangetic dolphin, Olive ridley turtle, Bay of Bengal

For Mains: Sundarbans, Challenges Related to Sundarban

Source: Statesman

Why in News?

Recently, a study conducted by prominent environmental scientists has warned about the substantial threat of air pollution to the Sundarbans, an essential mangrove ecosystem in West Bengal.

What is Sundarbans?

  • About:
    • The Sundarbans hosts the largest mangrove forests in the world, lying on the delta of the Ganges, Brahmaputra and Meghna rivers on the Bay of Bengal.
    • The mangrove ecosystem is a ecotone between the land and the sea in the tropical and subtropical regions.
  • Flora and Fauna:
    • Due to the ecotonic effect this zone fosters a rich blend of habitats, from freshwater swamps and intertidal mangroves to saline forests and open water.
  • Protection:
    • 40% of Sundarban lies in India and the rest in Bangladesh.
    • It was designated a UNESCO World Heritage site in 1987 (India) and 1997 (Bangladesh).
    • Sundarban Wetland, India was recognised as the ‘Wetland of International Importance’ under the Ramsar Convention in January 2019.
    • Project Tiger: Royal Bengal Tigers in the Sundarbans are top predators that control prey populations, preventing overgrazing and maintaining the delicate balance of the ecosystem.
      • Protecting tigers also safeguards a vast habitat for other plant and animal species, contributing to a healthy forest ecosystem in the Sundarbans.
    • In 2011, India and Bangladesh signed an MoU on Conservation of the Sundarbans, recognising the need to monitor and conserve the Sundarbans.

What are the Challenges Faced by the Sundarbans?

  • Rising Sea Levels: A consequence of climate change, rising sea levels threaten to inundate low-lying mangroves. This saltwater intrusion disrupts their delicate balance and makes them more vulnerable to storm surges during cyclones.
  • Increased Intensity of Cyclones: Climate change is also linked to more frequent and intense storms. These cyclones can batter mangroves, causing physical damage and disrupting sediment patterns crucial for their survival.
  • Cash and Food Crops: The conversion of mangrove forests for agriculture like cash crops (palm oil) or food production (rice paddies) destroys their habitat.
    • This not only reduces the area available for these ecosystems but also fragments existing ones, impacting biodiversity.
  • Loss of Ecosystem Services: Mangroves provide crucial services like shoreline protection and nursery grounds for fish. Deforestation disrupts these services, impacting coastal communities and fisheries.
  • Threat to Wildlife: The loss of mangrove habitats due to climate change is leading to the loss of species in the near-threatened or endangered category.
    • Settlement mangroves used to be safe havens for diverse molluscs and crustaceans, but they are disappearing due to polluted discharges and breeding activities of these species.
  • Effect of Pollutants: Pollutants, enriched with black carbon or soot particles, from nearby urban areas and the entire Indo-Gangetic Plain region are worsening the air quality of the Sundarbans, impacting its ecosystem.
    • These air pollutants significantly affect the ecology and biogeochemistry of the Sundarbans mangrove ecosystem.

Way Forward

  • Protecting Streambanks: Cultivating native grass species like wild rice, Myriostachya wightiana, biscuit grass, and salt couch grass can stabilise streambanks and prevent erosion, instead of introducing non-local species like vetiver, which are not salt-tolerant.
  • Promoting Sustainable Agriculture: Promoting soil-tolerant paddy varieties and organic agriculture practices can increase agricultural productivity and income for farmers while minimising environmental impact.
  • Wastewater Treatment: Using natural processes and microorganisms for wastewater treatment, such as lactic acid bacteria and photosynthetic bacteria, can support water quality and ecosystem health.
  • India-Bangladesh Collaboration: The India-Bangladesh Joint Working Group (JWG) should be transformed into a high-powered board of interdisciplinary experts to plan and implement climate resilience for the Sundarbans and the communities dependent on it.
  • Innovative Solutions: The corrective measures include solar energy promotion,electric transportation, subsidised LPG, regulated tourism, closing down of pollutant factories, regulation of brick kilns and land use and strengthening of coastal regulations.
  • Multi-Sectoral Approach: A multilayered approach to multi-engagement and multidimensional planning can be followed by the ministries of tourism, disaster management, agriculture, fisheries, and rural development.

For Mains: Key highlights of Global report on neglected tropical diseases (NTD) of 2024, About Neglected Tropical Diseases and related initiatives.

Source: WHO

Why in News?

Ahead of the World Health Assembly 77th session, the World Health Organization (WHO) released its Global report on neglected tropical diseases (NTD) of 2024.

  • The report provides an account of the progress made in 2023 towards the implementation of the Road map for neglected tropical diseases 2021-2030.

What are the Key highlights of the WHO Report?

  • Global:
    • Status for 2023:
      • As of December 2023, a total of 50 countries have successfully eliminated at least one NTD, marking the halfway point towards the 2030 target of 100 countries.
      • 5 countries were acknowledged by WHO for eliminating one NTD, and 1 country for eliminating two NTDs.
      • In July 2023, Iraq became the 50th country to eliminate at least one NTD. This event marks the halfway point towards achieving the 100-country target set for 2030.
      • Noma was added to the list of NTDs in 2023.
      • In October 2023, Bangladesh became the first country to be validated by WHO for eliminating visceral leishmaniasis as a public health problem.
    • Status for 2022:
      • In 2022, 1.62 billion people required interventions against neglected tropical diseases (NTDs), reflecting a 26% decrease from 2010, but still dedicated efforts are needed to attain the road map’s global target of a 90% reduction by 2030.
      • In 2022, approximately 848 million people received treatment for at least one NTD through preventive chemotherapy interventions, 49 million fewer than in 2021 but 50 million more than in 2020.
      • As of the end of 2022, the number of reported deaths from vector-borne NTDs has increased by 22% (as compared with 2016).
  • India:
    • India was certified free of NTDs like dracunculiasis and yaws.
    • India, which has the highest disease burden, treated about 117 million fewer people for lymphatic filariasis and soil-transmitted helminthiasis in 2022 compared to 2021.
    • 40.56% of India's population needed interventions against NTDs in 2022.
  • Key challenges highlighted in the report include slow post Covid-19 recovery, funding uncertainties, geopolitical disruptions, climate change, gaps in knowledge and tools, and insufficient data in addressing NTDs.

What are the Key Facts About Neglected Tropical Diseases (NTDs)?

  • About:
  • Factors Contributing to these Diseases are Being "Neglected":
    • The epidemiology of NTDs is complex and often related to environmental conditions.
      • Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population.
    • Many of them are vector-borne, have animal reservoirs and are associated with complex life cycles.
    • Compared to diseases like HIV/AIDS, malaria, and tuberculosis, NTDs receive significantly less funding for research and development of treatments.

What are the Global and Indian Initiatives to tackle NTDs?

  • Global Initiatives:
    • WHO's 2021-2030 Roadmap: This ambitious plan prioritises impact over simply treating NTDs. It emphasises collaboration across healthcare, sanitation, and communities. Additionally, it encourages countries to take ownership of their NTD programs.
    • 2012 London Declaration: This international agreement recognises the global burden of NTDs and promotes a unified approach to eliminate them.
  • Indian Initiatives:
    • Elimination Programs: India has successfully eliminated guinea worm, trachoma, and yaws. The Accelerated Plan for Elimination of Lymphatic Filariasis (APELF) aims to achieve the same for this disease by 2027.
    • WHO Collaborations: India partners with WHO in regional alliances. For instance, a 2005 initiative with Bangladesh and Nepal focuses on early diagnosis and treatment of Kala-azar.
    • Mass Drug Administration (MDA): This program involves regular distribution of free anti-parasitic medication in high-risk areas to prevent NTD transmission.
    • Vector Control: Programs like Indoor Residual Spraying target insect breeding grounds to prevent the spread of NTDs like Kala-azar.
    • Financial Assistance: Wage compensation schemes help individuals affected by NTDs, particularly those with Post-Kala Azar Dermal Leishmaniasis, manage the financial burden of their illness.

Conclusion

The 2024 WHO report shows progress in the fight against neglected tropical diseases. Several countries eliminated these diseases in 2023, but more needs to be done to reach global targets. Challenges like funding gaps and the lingering effects of COVID-19 threaten progress. Increased national and global collaboration is necessary for achieving a future free from neglected tropical diseases.

SC Declines Plea Against Collegium System

For Prelims: Supreme Court, Collegium system, National Judicial Appointments Commission (NJAC), Parliament, Chief Justice of India(CJI), Executive, First Judges Case (1981), Second Judges Case (1993), Third Judges Case (1998)

For Mains: Evolution of the Collegium System and its Criticism

Source: TOI

Why in News?

Recently, two senior-most district judges moved to the Supreme Court alleging that the Himachal Pradesh HC collegium overlooked their merit and seniority in the selection process of judges, and have taken their grievances to the Supreme Court.

What is a Collegium System and How Did It Evolve?

  • About:
    • It is the system of appointment and transfer of judges that has evolved through judgments of the SC, and not by an Act of Parliament or by a provision of the Constitution.
      • Articles 124(2) and Article 217 of the Indian Constitution deal with the appointment of judges to the Supreme Court and High Courts.
      • The Supreme Court has already upheld the collegium system, and struck down NJAC -which gave an equal role to the government in judicial appointments — by a Constitution Bench in 2015. A review plea against the judgement was also subsequently dismissed in 2018.

Collegium System According to Third Judges Case (1998):

Appointment of Supreme Court Judge Appointment of High Court Judge Transfer of High Court Judge
4 senior-most judges of the Supreme Court. 2 senior-most judges of the Supreme Court 4 senior-most judges of the Supreme Court along with the judges of the two High Courts in concern.

What are the Issues Related to the Collegium System?

  • Exclusion of Executive:
    • The complete exclusion of the executive from the judicial appointment process created a system where a few judges appoint the rest in complete secrecy.
    • Also, they are not accountable to any administrative body that may lead to the wrong choice of the candidate while overlooking the right candidate.
  • Chances of Favouritism and Nepotism:
    • The collegium system does not provide any specific criteria for testing the candidate for the post of CJI because of which it leads to wide scope for nepotism and favouritism.
      • For instance, as per the two senior-most district judges, the Himachal Pradesh HC collegium had ignored the SC collegium's advice in the selection process of judicial officers much junior to them, bypassing their merit, seniority, and "unblemished judicial track record."
    • Allegedly, the collegium system gives rise to non-transparency of the judicial appointments, which is very harmful for the regulation of law and order in the country.
  • Against the Principle of Checks and Balances:
    • The principle of check and balance is violated in this system. In India, three organs work partially independently but they keep check and balance and control the excessive powers of any organ.
    • However, the collegium system gives the Judiciary immense power, which leaves little room for checks and poses the risk of misuse.
  • Close-Door Mechanism:
    • Critics have pointed out that this system does not involve any official secretariat. It is seen as a closed-door affair with no public knowledge of how and when a collegium meets, and how it takes its decisions.
    • Also, there are no official minutes of collegium proceedings.
  • Unequal Representation:

Way Forward

  • Ensuring Transparency and Objectivity:
    • Clear and objective criteria for selection, including factors like merit, seniority, and diversity should be developed.
    • A mechanism for recording and publishing collegium decisions, while protecting legitimate privacy concerns should be implemented.
  • Balancing Independence and Accountability:
    • There is a need to find a way to involve the government in the appointment process without compromising judicial independence. This could involve a consultative mechanism or a time-bound confirmation process.
    • For example: The National Commission to Review the Working of the Constitution (NCRWC) recommended:
      • Establishment of a National Judicial Commission under the Constitution.
      • Examination of complaints of deviant behaviour of SC and HC judges by a committee of the National Judicial Commission.
      • Setting up of a National Judicial Council and Judicial Council in states for the preparation of plans and annual budget proposals.
  • Promoting Diversity:
    • There is a need to implement affirmative action measures to increase the representation of women, minorities, and disadvantaged social groups in the judiciary.
    • For instance, the issue of nepotism or 'Uncle Judges' syndrome’ in judicial appointments was addressed by the Law Commission of India (230th Report).
    • It recommended that judges not be appointed to High Courts where their family members have legal practices.

Conclusion

The solution lies in balancing competing interests. The executive must demonstrate a genuine commitment to judicial independence, while the judiciary should be sensitive in maintaining transparency in judicial appointments. This inherent tension is essential for a healthy check and balance system that safeguards individual rights and the Constitution.

      World Lupus Day, observed annually on 10th May, is a crucial event that aims to shed light on the challenges faced by individuals living with lupus. This complex autoimmune disease affects millions worldwide.

      • Lupus causes the immune system to attack the body's own tissues and organs, leading to symptoms like joint pain, rashes, fever, and fatigue. It can also result in severe complications like osteoporosis and cardiovascular issues.
        • Factors such as genetics, smoking, hormones, environmental influences, and stress can increase the risk of developing lupus.
      • Established in 2004 by the World Lupus Federation, World Lupus Day aims to spread awareness and rally global support for lupus patients.
      • With nearly 5 million sufferers worldwide, this day emphasises the need for better healthcare, increased research, early diagnosis, and improved treatments for lupus. It also aims to unite organisations and individuals in reducing the suffering caused by this potentially fatal disease.

      In a proactive move to address the persistent problem of landslides in the ecologically sensitive Nilgiris region, the State highways department is implementing a sustainable 'green' solution using the soil nailing and hydroseeding technique.

      • Soil nailing is a geotechnical engineering technique that involves the insertion of reinforcing elements into the soil to strengthen it and prevent soil erosion.
      • Following the soil nailing process, the 'hydroseeding' method will be applied, which involves the application of a mixture of seeds, fertiliser, organic materials, and water onto the soil to facilitate the growth of grass and plant-life.
        • Around five species of grasses, including a few local species native to India, will be grown along the slopes.
        • The highways department will be responsible for the maintenance of the grasses once the hydroseeding is completed.
      • This 'green' solution of preventing landslides through soil nailing and hydroseeding will help mitigate the impact of linear infrastructure, such as roads, in the ecologically sensitive Nilgiris region.
