Expanding Glacial Lakes in the Himalayas

Source: TH

Why in News?

Recently, satellite monitoring data by the Indian Space Research Organisation (ISRO) has shown a large expansion in glacial lakes between 1984 and 2023 in the Himalayan region, which has posed an alarming situation for the downstream areas.

What are ISRO’s Observation on Expansion of Himalayan Glaciers?

• Key Findings:
  • Of the 2,431 lakes larger than 10 hectares identified during 2016-17, 676 glacial lakes have notably expanded since 1984.
    • 130 of these lakes are situated within India, with 65, 7, and 58 lakes located in the Indus, Ganga, and Brahmaputra River basins, respectively.
    • Of these lakes 601 lakes (89%) have expanded more than twice, 10 lakes have grown between 1.5 to 2 times and 65 lakes at 1.5 times.
  • Elevation-based analysis reveals that 314 lakes are located in the 4,000 to 5,000 m range and 296 lakes are above 5,000 m elevation.
  • Long-term changes in the Ghepang Ghat glacial lake (Indus River Basin) at an elevation of 4,068 m in Himachal Pradesh, India, show a 178% increase in size from 36.49 to 101.30 hectares between 1989 and 2022.
• Types and Number of Glacial Lakes in Himalayas:
  • Moraine-dammed (307): They are formed when piles of rocks and debris (moraines) left behind by retreating glaciers block valleys, creating natural dams that hold back meltwater.
  • Ice-dammed (8): They are formed when a glacier itself acts as a dam, blocking the flow of meltwater.
  • Erosion (265): These lakes occupy depressions carved directly into bedrock by glaciers.
  • Other Glacial lakes (96)

What are the Causes of Expanding Glacial Lakes in Himalayas?

• Global Warming: It is causing temperatures to rise in the Himalayas, leading to increased melting of glaciers. This meltwater feeds into existing glacial lakes, causing them to expand in size.
• Retreating Glaciers: As glaciers melt, they not only contribute water to the lakes but also expose new land surfaces. This allows for the formation of new glacial lakes.
• Weakening Moraines: Glaciers are often dammed by natural walls of rock and debris called moraines.
  • As glaciers shrink, these moraines become weaker and more susceptible to collapse. A sudden collapse can trigger a Glacial Lake Outburst Flood (GLOF), a catastrophic event where a large volume of water is released downstream.
• Increased Precipitation: Changes in precipitation patterns, including increased rainfall and snowfall in the region, can contribute to the expansion of glacial lakes by providing more water to fill them.
• Permafrost Thaw: Permafrost, which is soil that remains frozen year-round, acts as a natural barrier to water drainage.
  • As permafrost thaws due to warming temperatures, it can create depressions that collect water, contributing to the expansion of glacial lakes.
• Human Activities: Infrastructure development, such as roads and hydropower projects, can alter the natural drainage patterns of glacial lakes, leading to their expansion.
  • Additionally, activities such as mining and deforestation can indirectly contribute to glacial lake expansion by accelerating climate change.

Way Forward

• Climate Change Mitigation: Addressing the root cause of glacial melt and retreat by reducing greenhouse gas emissions is crucial.
  • This involves global efforts to mitigate climate change through measures such as transitioning to renewable energy, increasing energy efficiency, and implementing policies to reduce carbon emissions across various sectors.
• Early Warning Systems: Developing and implementing early warning systems for monitoring of glacial lakes, weather forecasting, and communication networks to disseminate timely alerts to at-risk communities.
• Engineering Measures: Implementing engineering measures to stabilize and manage glacial lakes can help reduce the risk of GLOFs.
  • This may involve constructing infrastructure such as spillways, drainage channels, and dams to control water levels and prevent uncontrolled releases of water.
• Natural Infrastructure: Restoring and conserving natural ecosystems, such as wetlands and forests, can help regulate water flow. These natural infrastructure solutions can also provide additional benefits, such as habitat conservation and carbon sequestration.
• Community Engagement and Capacity Building: Involving local communities in risk assessment, planning, and decision-making processes is essential for effective glacial lake management.
  • Building local capacity for disaster preparedness, including training in emergency response and evacuation procedures, can help communities better cope with GLOFs and other hazards.
• International Cooperation: Given the transboundary nature of many glacial lakes in the Himalayas, international cooperation is essential for effective management and risk reduction.
  • Collaborative efforts among countries sharing glacier-fed river basins can facilitate information sharing, joint monitoring, and coordinated action to address common challenges.

WHO Report on Global Immunisation

Source: WHO

Why in News?

Recently, a study by the World Health Organisation (WHO) revealed that Global Immunisation efforts have saved an estimated 154 million lives over the past 50 years.

• The Report was released on the occasion of World Immunization Week, ahead of the 50th anniversary of the Expanded Programme on Immunization (EPI) to take place in May 2024.

What are the Key Findings of the Report?

• Report shows that Immunization is the single greatest contribution of any health intervention to ensuring healthy lives of babies.
• Measles vaccination:
  • Nearly 94 million of the estimated 154 million lives saved since 1974, were a result of protection by measles vaccines.
    • There are still 33 million children who missed a measles vaccine dose in 2022.
  • Currently, the global coverage rate of the first dose of measles vaccine is 83% and the second dose is 74%, contributing to a very high number of outbreaks across the world.
    • Coverage of 95% or greater with 2 doses of measles-containing vaccine is needed to protect communities from outbreaks.
  • It accounts for 60% of the lives saved due to immunisation and the vaccine likely remain the top contributor to preventing deaths in the future.
• Coverage for DPT Vaccine:
  • Before the launch of EPI, less than 5% of infants globally had access to routine immunisation.
  • Today, 84% of infants are protected with 3 doses of the vaccine against diphtheria, tetanus and pertussis (DTP).
    • DPT refers to a class of combined vaccines given to protect against three infectious diseases in humans (diphtheria, pertussis or whooping cough and tetanus).
• Reduced Infant Deaths:
  • 40% Reduction in infant death for 14 diseases like Diphtheria, Haemophilus influenzae type B, Hepatitis B, Japanese encephalitis, measles, meningitis A, pertussis, invasive pneumococcal disease, polio, rotavirus, rubella, tetanus, tuberculosis, and yellow fever.
  • Above 50% reduction in the African Region over the past 50 years.
• Eradication and Containment of Disease:
  • Wild poliovirus cases have decreased by over 99% since 1988. Of the 3 strains of wild poliovirus (type 1, type 2 and type 3), wild poliovirus type 2 was eradicated in 1999 and wild poliovirus type 3 was eradicated in 2020.
  • India was declared polio-free by the World Health Organisation (WHO) in 2014.
  • Vaccines against malaria and cervical cancer have been highly effective in containment of these diseases.
• Gain in Full Health Years:
  • For each life saved through immunisation, an average of 66 years of full health were gained.
  • With a total of 10.2 billion full health years gained over the five decades.

What is the Status of Immunization In India?

• About:
  • India's immunisation programme, UIP (Universal Immunization Programme), is one of the world's most extensive public health programmes.
  • Under the UIP, India annually vaccinated more than 30 million pregnant women and 27 million children.
    • A child is considered fully immunised if they receive all the required vaccines as per the national immunisation schedule within their first year of life.
• Status:
  • The country was certified polio-free in 2014 and eliminated maternal and neonatal tetanus in 2015.
  • New vaccines, including the Measles-Rubella, Pneumococcal Conjugate Vaccine (PCV) and Rotavirus Vaccine (RVV), have been introduced and expanded nationwide.
  • According to UNICEF, only 65% of children in India receive full immunisation during the first year of their life.
  • Also, as per the latest WUENIC (WHO-UNICEF Estimates National Immunization Coverage) estimates, India has successfully reduced the number of zero-dose (ZD) children to 1.1 million in 2022 from 2.7 million in 2021, covering an additional 1.6 million children with life-saving vaccination.
    • Zero-dose refers to children who failed to receive any routine vaccination.
    • 63% of ZD children live in the five states of Bihar, Madhya Pradesh, Maharashtra, Rajasthan and Uttar Pradesh.
  • Mission Indradhanush (MI) was launched by the Ministry of Health and Family Welfare (MOHFW) in 2014 with the aim to vaccinate all unvaccinated and partially vaccinated children under UIP.
    • Intensified Mission Indradhanush (IMI) has been launched to bring down the number of zero-dose children.
• Other Supporting Measures:
  • Electronic Vaccine Intelligence Network (eVIN)
  • National Cold Chain Management Information System (NCCMIS).
• Challenges:
  • Lack of Access:
    • In 2022, 14.3 million infants did not receive the first DPT vaccine globally, pointing to a lack of access to immunisation and other health services.
    • Of the 20.5 million who are either not vaccinated or partially vaccinated, nearly 60% of children live in 10 countries, including India.
  • Death by Infectious Diseases:
    • It contributes to a significant proportion of child mortality and morbidity.
    • Nearly one million children die before their fifth birthday.
    • Many of these deaths are preventable and can be averted by interventions such as breastfeeding, immunisation and access to treatment.
  • Full Coverage Goal Still to Achieve: According to National Family Health Survey (NFHS)-5, 2019-21, the country's full immunisation coverage stands at 76.1%.
    • It means that one out of every four children is missing out on essential vaccines.

What is the Universal Immunization Programme (UIP)?

• Background:
  • The Expanded Programme on Immunization was launched in 1978. It was renamed as Universal Immunization Programme in 1985 when its reach was expanded beyond urban areas.
  • Since the launch of the National Rural Health Mission in 2005, the Universal Immunization Programme(UIP) has always been an integral part of it.
• About:
  • Under UIP, immunisation is provided free of cost against 12 vaccine-preventable diseases.
    • Nationally Against 9 Diseases: Diphtheria, Pertussis, Tetanus, Polio, Measles, Rubella, severe form of Childhood Tuberculosis, Hepatitis B and Meningitis & Pneumonia caused by Haemophilus influenzae type B.
    • Sub-nationally Against 3 Diseases: Rotavirus diarrhoea, Pneumococcal Pneumonia and Japanese Encephalitis.

Drishti Mains Question: Discuss the importance of vaccination for healthcare, particularly in developing countries like India. Also, discuss the measures taken by India to ensure universal immunisation of our population.

Balanced Fertilisation

Source: IE

Why in News?

Post Lok Sabha elections 2024, balanced fertilisation is likely to be a key policy goal for the government taking over.

• Despite efforts to curb excessive fertiliser consumption, urea consumption has steadily increased in India, reaching a record 35.8 million tonnes in 2023-24 (up 16.9% since 2013-14).

What is Balanced Fertilization?

• About:
  • Balanced fertilisation is a practice in agriculture that focuses on providing plants with the optimal amounts of the nutrients that are needed for their healthy growth and development.
• Essential Nutrients:
  • Primary Nutrients: Nitrogen (N), Phosphorus (P), and Potassium (K) are the most crucial nutrients needed in larger quantities. They play vital roles in plant structure, energy production, and overall health.
  • Secondary Nutrients: Sulphur (S), Calcium (Ca), and Magnesium (Mg) are also essential but required in smaller amounts compared to primary nutrients.
  • Micronutrients: Trace elements like Iron (Fe), Zinc (Zn), Copper (Cu), Manganese (Mn), Boron (B), and Molybdenum (Mo) are needed in very small quantities but are still critical for specific plant functions.
• Right Proportion:
  • Balanced fertilisation emphasises supplying these essential nutrients in the correct ratios based on several factors:
    • Soil Type: Different soil types have varying levels of inherent nutrients. Testing the soil reveals its nutrient profile, guiding fertiliser selection and application rates.
    • Crop Requirements: Different crops have specific nutrient needs at different stages of growth. For example, legumes might require more nitrogen for nitrogen fixation, while fruits might benefit from additional potassium for better quality.

What are the Benefits Associated with Balanced Fertilisation?

• Improved Crop Yields:
  • By providing the optimal mix of nutrients, plants can grow to their full potential, leading to higher yields.
• Enhanced Crop Quality:
  • Balanced nutrients contribute to stronger plants with better resistance to pests and diseases, ultimately improving the quality of the harvest.
• Promotes Soil Health:
  • Overuse of single-nutrient fertilisers can disrupt soil health. Balanced fertilisation helps maintain a healthy soil ecosystem, promoting long-term sustainability.
• Reduced Environmental Impact:
  • Excessive fertiliser application can contribute to nutrient runoff, polluting water bodies. Balanced use minimises this risk.
• Cost-Effectiveness:
  • By preventing over-fertilisation and nutrient deficiencies, balanced fertilisation can optimise resource utilisation and reduce overall fertiliser costs.

What are the Challenges related to Balanced Fertilisation?

• Price Distortions:
  • Urea, a single-nutrient nitrogen fertiliser, is heavily subsidised by the government, making it cheaper than other fertilisers like DAP (diammonium phosphate) containing phosphorus and MOP (muriate of potash) containing potassium.
  • This incentivises overuse of urea and neglects other crucial nutrients.
• Distorted Fertiliser Pricing Hinders Potash Use:
  • The current system for setting fertiliser prices fails to consider market forces, leading to imbalances. For example, the price of Muriate of Potash (MOP), a key source of potassium, is too high for both farmers using it directly and fertiliser companies including it in blends.
  • This discourages MOP use, contributing to widespread potassium deficiencies in Indian farms.
• Soil Testing Infrastructure:
  • Lack of adequate soil testing facilities in the rural and remote areas of India, makes it difficult for farmers to access them for balanced fertilisation.
  • Even if tests are done, interpreting the results and translating them into fertiliser recommendations requires proper training and mechanism for both farmers and extension workers.
• Farmer Awareness and Education:
  • Many farmers lack awareness about soil testing and the specific needs of their crops.
  • Traditional practices and limited knowledge mostly hinders adoption of balanced fertilisation techniques .
    • It is due to the lack of precise fertiliser application techniques resulting in issues of over-fertilisation and under-fertilisation alongwith limited focus on micronutrients.
• Limited Success of Past Schemes:
  • The Nutrient-Based Subsidy (NBS) scheme, meant to encourage balanced use, failed because it didn't address urea pricing. Urea consumption continued to rise despite NBS.

What Steps Can be Taken by India to Achieve Balanced Fertilisation?

• Integrated Nutrient Management (INM):
  • It recognises the limitations of relying solely on chemical fertilisers or organic matter.
  • It advocates for a holistic approach that combines:
    • Chemical Fertilisers: Provide essential nutrients like NPK.
    • Organic Matter: Improves soil health, water retention, and nutrient availability. This includes manure (cow dung), compost, and crop residues (dhaincha crop).
    • Crop Rotations: Introducing diverse crops helps break pest and disease cycles and improves nutrient utilisation.
• Customising Fertilisers Using Technology:
  • Customised fertilisers are multi-nutrient carriers containing macro and micronutrients for satisfying crop needs that are site-specific and validated by scientific crop models.
  • It is the emerging concept based on the balanced nutrient fertilisation approach to address the crops' multiple nutrient needs.
  • In Israel, some remarkable steps are being followed:
    • High-resolution soil mapping and its integration with Geographic Information Systems (GIS) to create user-friendly maps and fertiliser application recommendations for farmers.
    • Advanced laboratory analyses go beyond basic NPK tests and delve into micronutrients, organic matter content, and cation exchange capacity (CEC).
• Advanced Approaches Beyond Soil Testing:
  • Soil Test Crop Response (STCR):
    • Tailors fertiliser recommendations based on specific soil type, crop variety, and climatic conditions.
    • It considers nutrient uptake by the crop and soil nutrient availability.
  • Diagnosis and Recommendation Integration System (DRIS):
    • Analyses plant tissue for nutrient ratios (e.g., N/P, N/K) and compares them to established optimal ratios for high yields.
    • Deficient nutrients are then supplemented through top dressing. (More suitable for long-duration crops).
• Other Steps:
  • Farmer Education and Training: Equipping farmers with the knowledge and skills to implement these approaches effectively.
  • Improved Market Access: Ensuring the availability of customised fertilisers and micronutrients at reasonable prices.
  • Policy and Subsidy Reforms: Encouraging the use of balanced fertilisers through targeted subsidies and promoting sustainable practices.
  • Continued Research and Development: Developing new technologies and crop-specific nutrient management solutions.

Conclusion

• Balanced fertilisation offers a compelling solution to numerous challenges in Indian agriculture. Sri Lanka's recent attempt at a rapid transition towards fully organic agriculture serves as a cautionary tale for Indian policymakers considering similar drastic shifts.
• By providing the right mix of nutrients to crops, it promises not only increased yields and improved quality but also enhanced soil health and reduced environmental impact.
• However, achieving balanced fertilisation on a large scale necessitates overcoming obstacles like skewed fertiliser pricing policies, limited soil testing infrastructure, and a knowledge gap among farmers.

Drishti Mains Question: Q. Discuss about balanced fertilisation and its associated benefits. Also, mention the key challenges and government initiatives related to it.

SC Rejects Centre's Plea for Administrative Spectrum Allocation

Source: TH

Why in News?

In a significant decision, the Supreme Court of India has refused to entertain the Centre's plea to allow the administrative allocation of spectrum, reaffirming the principle of open and transparent auction for allocating this scarce natural resource.

• The electromagnetic spectrum encompasses a range of radio frequencies, which are utilised by wireless devices for communication, including making calls and accessing social media.

Why Did the Supreme Court Reject the Centre's Application?

• The Registrar found the application for clarification to be misconceived, the Registrar invoked Order XV Rule 5 of the Supreme Court Rules, 2013, which allows refusal to receive a petition if it lacks reasonable cause, is frivolous, or contains scandalous matter.
  • SC asserted that spectrum allocation to private players must be through open and transparent auction, as established by the landmark 2G spectrum case, often referred to as the “2G spectrum scam,” judgement 12 years ago.
• Spectrum allocation is a crucial process, and allowing "administrative allocation" would have placed the government solely in charge of selecting operators to distribute airwaves, a move deemed contrary to principles of fairness and transparency.

What is the Legal Framework Regarding the Allocation of Spectrum?

• Telecommunications Act, 2023:
  • It empowers the government to assign spectrum for telecommunication through administrative processes other than auction for entities listed in its First Schedule of the act.
    • These entities include those engaged in national security, defence, and law enforcement, as well as Global Mobile Personal Communication by Satellites such as SpaceX, and Bharti Airtel-backed OneWeb.
  • The government can also assign part of a spectrum that has already been assigned to one or more additional entities, known as secondary assignees, and even terminate assignments where a spectrum or a part of it has remained underutilised for insufficient reasons.

What is the 2G Spectrum Scam?

• 2G Spectrum Scam:
  • The 2G spectrum allocation scam dates back to 2008, the government then allegedly sold 122 licences on a first-come-first-serve basis (FCFS) to specific private telecom operators.
  • In 2009 ,the Central Vigilance Commission directed the Central Bureau of Investigation (CBI) to investigate claims that there were illegalities in the allocation of licences, following which the CBI filed a first information report against unknown officers of the Department of Telecommunications (DoT), private persons and companies.
  • In 2011, the CBI alleged that there was a loss of Rs 30,984 crore to the exchequer as a result of discrepancies in the allocation process.
• Supreme Court's Verdict:
  • In February 2012, the Supreme Court cancelled the 122 telecom licences that were allocated on a FCFS basis, stating that this method was prone to misuse.
    • The Court emphasised that the "non-discriminatory method" of auction should be adopted for the allocation of bnatural resources like spectrum to ensure fairness and transparency.
• Centre's Current Plea:
  • More than a decade after the Supreme Court's landmark 2G spectrum scam judgement, the Union government has moved an application for a "certain class" of spectrum to be allocated through administrative processes instead of competitive auctions.
  • The Centre has pointed out that the assignment of spectrum is required not only for commercial telecom services but also to discharge sovereign and public interest functions such as security, safety, and disaster preparedness.
    • The government has argued that administrative allocation is required when demand is lower than supply or for space communication, where it would be more optimal and efficient for spectrum to be shared by multiple players.

What was the 2012 Presidential Reference Regarding Natural Resource Allocation?

• The Union government cites observations from a Constitution Bench regarding a Presidential reference made concerning the 2012 verdict.
• The Bench clarifies that the auction method prescribed in the verdict is not a "constitutional mandate" for the alienation of natural resources excluding spectrum.
• It stated that the word "perhaps" in the verdict suggested that auction was not intended as a blanket principle for all natural resources, and other methods could be considered.
• However, it cautioned that spectrum must be allocated only through auction as per the law declared in the 2G case.

What are the Spectrum Allocation Methods Across the Globe?

• New Zealand: Initiated the use of auctions for spectrum allocation in 1989, a method that has since been adopted by many other countries, including those in emerging markets.
• United States: In the 1980s, the United States experimented with allocating cellular licences through lotteries, which attracted speculative applicants and resulted in notional losses for the government.
  • The lottery method, initially seen as faster and cheaper than the administrative process, has drawbacks.
    • It is susceptible to speculation and cannot reliably assess the technical competence of licensees.
  • In 1993, the US transitioned to auctions for granting new mobile communication licences.
    • This transition had a global impact, leading to over USD 100 billion in radio spectrum sales worldwide.
• Canada and European Union: These regions often use an administrative process, also known as a “beauty contest,” where criteria are set by the government and proposals are evaluated by an expert committee.
  • This method provides flexibility and government control, aligning decisions with government plans and objectives. However, it is time-consuming, but ensures adherence to government priorities.

Drishti Mains Question: Q. Discuss the significance of the recent Supreme Court decision regarding the administrative allocation of spectrum. How does this decision uphold the principles of fairness and transparency in resource allocation?

Diplomatic Passport

Recently, the topic of diplomatic passports has been in the news, particularly in relation to the power regarding the issuance and revocation of diplomatic passports.

• A passport is an official government-issued document that serves as a form of identification and travel document for individuals who wish to travel internationally.

What is a Diplomatic Passport?

• About:
  • Diplomatic passports are issued to individuals representing a country on official diplomatic missions or government business.
  • They are used by diplomats, government officials, and sometimes their immediate family members.
  • These passports are a form of identification and carry certain legal privileges and immunities under international law, such as immunity from arrest, detention, and certain legal proceedings in the host country.
• Eligibility: In India, the Ministry of External Affairs' Consular, Passport & Visa Division issues diplomatic passports, also known as 'Type D' passports, to individuals falling into several categories:
  • Government-appointed individuals and officers working under branches A and B of the Indian Foreign Service (IFS) traveling abroad for official business
  • Select individuals on official travel, including union ministers and Members of Parliament (MPs).
• Revoking Power:
  • The authority to revoke a diplomatic passport lies with the passport authority.
    • However, the government can revoke a diplomatic passport only after a court order to that effect.
  • Under the Passport Act of 1967, a diplomatic passport may be revoked if the holder is in wrongful possession, obtained it through suppression of material information, if the passport authority deems it necessary for India's interests, or if the holder has been convicted or is facing criminal proceedings in India.
• Difference Between Passport and Visa:

International Law Covering Diplomatic Passports

• Vienna Convention on Diplomatic Relations:
  • This convention outlines the rules for diplomatic law, including the privileges and immunities of diplomatic passport holders.
• Operational Visa Exemption Agreements:
  • It allows diplomatic passport holders to visit these countries without a visa for stays up to 90 days, provided their travel is not for private purposes.
  • India has operational visa exemption agreements with 34 countries, including Germany, for holders of diplomatic passports.

Study Advocates Removal of Exotic Plant Species

Source: TH

A recent study conducted by the Kerala State Forest Protective Staff Organisation (KSFPSO), an association of frontline forest officers highlights the importance of removing exotic plant species from forests to ensure ample food for wild animals, particularly elephants, at Chinnakkanal in Munnar, Kerala.

• The KSFPSO emphasises the necessity of removing exotic species like Acacia mearnsii (black wattle) and Eucalyptus (Eucalyptus teriticornis) from forest areas to mitigate human-elephant conflicts.
  • Exotic plants inhibit the growth of other species and restrict animal movement, leading to food scarcity for wildlife.
  • Changing these areas to natural grasslands will provide food and water for wild elephants at Chinnakkanal and improve the landscape.
• The Chinnakkanal landscape is overrun by West Indian Lantana (kongini), hindering the growth of diverse vegetation and posing challenges for animal access.
• Nearly 4,000 hectares of forestland in the district are affected by exotic species, impacting prey availability and consequently attracting predators like tigers and leopards to adjacent areas.
