1.From National Mission to Global Inspiration: Namami Gange’s Restoration Journey

Why in News?

The United Nations has recognised India’s Namami Gange Programme among the world’s Top 10 Restoration Flagships under the UN Decade on Ecosystem Restoration (2021–2030), placing it alongside some of the most significant ecosystem recovery initiatives globally.

Why the Recognition Matters?

• The recognition goes beyond river cleaning.
• It acknowledges India’s attempt to restore an entire river ecosystem through a combination of pollution control, biodiversity conservation, community participation, and basin-level governance.
• For a country where rivers support livelihoods, agriculture, drinking water, and cultural traditions, the success of Ganga restoration has implications extending far beyond environmental protection.

A Shift from River Cleaning to River Rejuvenation

• Unlike earlier efforts that focused largely on pollution abatement, Namami Gange adopted an integrated river basin approach.
• The programme seeks not only to reduce sewage and industrial discharge but also to restore ecological processes that sustain the river.
• The mission combines sewage treatment infrastructure, riverfront development, biodiversity conservation, afforestation, rural sanitation, and public participation under a single institutional framework led by the National Mission for Clean Ganga (NMCG).

Major Outcomes

• One of the most visible achievements has been the large-scale expansion of sewage treatment capacity across the Ganga basin.
• This has contributed to measurable improvements in water quality indicators across several stretches of the river.
• Ecological recovery is increasingly reflected in the revival of species such as the Gangetic Dolphin, which serves as an indicator of river health.
• Improved aquatic biodiversity suggests that restoration efforts are beginning to generate ecosystem-level benefits.

Challenges that Continue to Persist

• While sewage treatment capacity has increased significantly, actual utilisation of several STPs remains below installed capacity due to inadequate sewer connectivity.
• Tributary pollution from rivers such as Kali, Ramganga, Hindon and Gomti continues to affect the overall health of the Ganga basin despite improvements in the main stem.
• Growing levels of microplastics, pharmaceutical residues and other emerging contaminants are not adequately addressed by conventional treatment infrastructure.
• Floodplain encroachment and unplanned urban expansion have reduced the river’s natural capacity for groundwater recharge and pollution assimilation.
• Climate change-induced variability in river flows, including extreme floods and prolonged lean seasons, poses new challenges for maintaining ecological balance.

Broader Lessons for Environmental Governance

• The Namami Gange experience offers important lessons for environmental governance in India.
• First, ecosystem restoration requires a basin-wide perspective rather than isolated project-based interventions.
• Second, ecological conservation and economic development need not be viewed as competing objectives. Investments in clean rivers generate benefits in public health, tourism, biodiversity conservation, and climate resilience.
• Third, successful restoration depends upon institutional coordination across sectors and levels of government, an area where environmental programmes have often struggled.

Conclusion

The UN recognition validates India’s effort to move from pollution management towards ecosystem restoration. However, the true measure of success will not be international accolades but the long-term ecological health of the Ganga and its tributaries.

2.Electrification: The Missing Link in Global Climate Action

Why in News?

At the Bonn Climate Talks ahead of COP31, Turkey proposed a global target of achieving 35% electrification of final energy consumption by 2035. The proposal reflects growing recognition that the success of climate action will depend not merely on expanding renewable energy but on transforming how energy is consumed across economies.

Why Electrification Matters?

• Climate discussions have traditionally focused on increasing renewable energy generation.
• However, clean electricity can contribute to emission reduction only when economic activities currently dependent on fossil fuels are shifted to electricity-based systems.
• Today, electricity accounts for only about 20–21% of global final energy consumption, while the remaining share continues to depend largely on coal, oil, and natural gas. Electrification therefore represents the bridge between renewable energy production and actual decarbonisation of the economy.

Understanding the Electrification Challenge

• The global economy was built around fossil fuels. Transportation, industries, buildings, and agriculture continue to rely heavily on direct combustion of oil, coal, and gas.
• While sectors such as household lighting, appliances, and digital services have become increasingly electrified, several critical sectors remain difficult to transition.
• Heavy industries such as steel, cement, chemicals, and aluminium require high-temperature heat that is traditionally generated using fossil fuels.
• Similarly, aviation, shipping, and long-haul freight transport continue to face technological and cost barriers in adopting electric alternatives.
• As a result, electrification has progressed unevenly across sectors.

The Climate Significance of Electrification

• Electrification offers multiple climate benefits.

• First, it enables direct replacement of fossil fuels with renewable electricity, reducing greenhouse gas emissions.
• Second, electric technologies are generally more energy-efficient than fossil-fuel-based alternatives. Electric vehicles, for instance, convert a much larger share of energy into useful work compared to internal combustion engines.
• Third, a highly electrified economy allows better integration of emerging clean technologies such as battery storage, smart grids, green hydrogen, and distributed renewable systems.
• According to the International Renewable Energy Agency (IRENA), achieving the 1.5°C target requires global electrification levels to reach approximately 35% by 2035, making it one of the most important pillars of climate mitigation.

Key Challenges

• A major challenge is that electrification alone does not guarantee decarbonisation. Nearly half of the world’s electricity generation still comes from fossil fuels.
• If electricity itself is generated from coal and gas, the climate benefits remain limited.
• Infrastructure constraints present another obstacle. Large-scale electrification requires massive expansion of transmission networks, distribution systems, storage facilities, and charging infrastructure.
• The financial requirement is equally daunting. Estimates suggest that around $1.2 trillion annually will be needed to modernize electricity systems and support the energy transition.
• Geopolitical instability, supply-chain disruptions, and economic uncertainties further complicate investments in clean energy infrastructure.

Conclusion

The future of climate action will depend not only on how much renewable energy the world produces but also on how effectively economies replace fossil-fuel-based consumption with clean electricity. Electrification has emerged as the critical missing link in the global energy transition. Without a significant increase in electrification levels, achieving the goals of the Paris Agreement will remain difficult despite continued growth in renewable energy capacity.

3.Sickle Cell Anaemia Elimination Mission: Towards a Disease-Free India by 2047

Why in News?

President Droupadi Murmu has expressed confidence that India can eliminate Sickle Cell Anaemia (SCA) before the target year of 2047. She emphasized the need for greater awareness, early diagnosis, and community participation, particularly among tribal populations where the disease burden remains significantly high.

Understanding Sickle Cell Anaemia

• Sickle Cell Anaemia is a hereditary blood disorder caused by a mutation in the gene responsible for producing haemoglobin.
• The abnormal haemoglobin causes red blood cells to become rigid, sticky, and sickle or crescent-shaped instead of their normal flexible disc shape.
• These abnormal cells obstruct blood flow through small blood vessels, resulting in recurrent pain episodes, anaemia, infections, organ damage, and reduced life expectancy.
• Since the disease is inherited, it cannot spread through contact and is transmitted genetically from parents to children.

Why It Is a Major Public Health Concern in India?

• India carries one of the world’s largest burdens of sickle cell disease, particularly among tribal communities.
• Scientific studies indicate that the prevalence of the sickle cell trait ranges from 1% to 40% among different tribal groups.
• The disease is concentrated in the tribal belt stretching across central and western India, covering states such as Madhya Pradesh, Chhattisgarh, Maharashtra, Gujarat, Odisha, Jharkhand, and parts of Rajasthan.

Several factors contribute to its persistence:

• Endogamous marriage practices within communities increase the probability of inheriting defective genes.
• Limited access to healthcare facilities delays diagnosis and treatment.
• Low awareness regarding genetic inheritance leads to continued transmission.
• Inadequate screening and counselling mechanisms historically prevented early intervention.

As a result, SCA remains both a health challenge and a social-development issue affecting vulnerable populations.

National Sickle Cell Anaemia Elimination Mission

• Recognising the magnitude of the challenge, the Government of India launched the National Sickle Cell Anaemia Elimination Mission in July 2023.
• The mission seeks to eliminate the disease as a public health problem by 2047 through a comprehensive strategy focused on prevention, early detection, and management.

Key components include:

• Large-scale screening of individuals below 40 years of age in high-prevalence districts.
• Universal identification of carriers and patients through community-based testing.
• Genetic counselling to help families understand inheritance patterns.
• Distribution of genetic status cards for informed marital and reproductive decisions.
• Strengthening treatment facilities and ensuring affordable healthcare access.
• Community awareness campaigns in local languages through schools, health workers, and tribal institutions.

Significance of the Mission

• The mission represents a shift from disease treatment to disease prevention.
• By identifying carriers before marriage and promoting informed reproductive choices, the programme seeks to break the cycle of genetic transmission.
• It also advances the objectives of inclusive healthcare by targeting historically underserved tribal populations.
• Improved screening and counselling can reduce infant mortality, disability, and healthcare expenditure associated with lifelong disease management.
• Further, the mission aligns with the broader goals of social justice, health equity, and human capital development envisioned under Viksit Bharat 2047.

Challenges Ahead

• Concentration of cases in remote tribal areas complicates screening and follow-up.
• Gap between mass screening efforts and availability of comprehensive care facilities.
• Lack of a robust national patient registry for effective disease tracking.
• Limited affordability and accessibility of curative therapies such as bone marrow transplantation

Conclusion

The National Sickle Cell Anaemia Elimination Mission represents one of India’s most ambitious public health initiatives aimed at addressing a hereditary disease affecting vulnerable communities. While the goal of elimination by 2047 is challenging, sustained screening, genetic counselling, community participation, and healthcare strengthening can transform it into a major public health success story and a model for genetic disease control globally.

5.Expanding Glacial Lakes in Arunachal Pradesh: A Growing Climate and Disaster Challenge

Why in News?

A recent satellite-based study in Arunachal Pradesh’s Tawang district has revealed significant expansion of four high-risk glacial lakes in the Mago Chu basin over the last decade. The findings have renewed concerns regarding the increasing threat of Glacial Lake Outburst Floods (GLOFs) in the Eastern Himalayas, particularly in the aftermath of the devastating South Lhonak Lake disaster in Sikkim in 2023.

Understanding Glacial Lakes and GLOFs

• Glacial lakes are water bodies formed by the accumulation of meltwater in depressions created by retreating glaciers. These lakes are often dammed by loose deposits of rock, soil, and debris known as moraines.
• A Glacial Lake Outburst Flood (GLOF) occurs when the natural dam holding back a glacial lake suddenly fails, releasing enormous volumes of water downstream.
• Such events can trigger flash floods, landslides, infrastructure destruction, and large-scale loss of life in mountain regions.
• As climate change accelerates glacier melting, glacial lakes are increasing both in number and size across the Himalayan region, thereby elevating disaster risks.

What the Recent Study Reveals?

• The assessment, based on high-resolution satellite imagery from ICEYE, PlanetScope, and LISS-IV, found that four out of five high-risk lakes in the Mago Chu basin have expanded considerably.
• Among them, Sanhapo Lake recorded the most rapid growth, increasing significantly in area within a few years.
• The expansion reflects a broader trend of glacier retreat and rising meltwater accumulation driven by increasing temperatures.
• While lake expansion does not automatically imply an imminent flood, it indicates growing instability and warrants continuous monitoring.

Why the Eastern Himalayas Are Vulnerable?

• The Eastern Himalayas are highly sensitive to climate change due to their unique geographical and climatic conditions.
• Rapid warming has accelerated glacier retreat across the region. As glaciers shrink, meltwater accumulates behind unstable moraine dams, increasing the possibility of catastrophic breaches.

The risk becomes even greater when combined with external triggers such as:

• Landslides falling into glacial lakes
• Avalanches entering water bodies
• Earthquakes destabilizing moraine structures
• Intense rainfall events linked to climate change

Implications for India

• The expansion of glacial lakes presents a multidimensional challenge involving disaster management, climate adaptation, water security, and infrastructure planning.
• Hydropower projects, roads, bridges, military installations, and settlements located in downstream valleys face increasing risks.
• This is particularly significant in Arunachal Pradesh, where strategic infrastructure development is expanding rapidly.
• The threat also has implications for river basin management, as sudden flood surges can affect communities far beyond the immediate mountain regions.
• Furthermore, increasing glacial instability serves as a visible indicator of the broader consequences of climate change on fragile Himalayan ecosystems.

Government Initiatives

Recognizing the growing threat, the National Disaster Management Authority (NDMA) has identified 189 high-risk glacial lakes across the Indian Himalayan Region for monitoring and mitigation.

The National Glacial Lake Outburst Floods Risk Mitigation Programme focuses on:

• Scientific assessment of vulnerable lakes
• Satellite-based monitoring systems
• Hazard zonation and risk mapping
• Development of early warning systems
• Community preparedness and evacuation planning

Remote sensing technologies have become particularly important because many glacial lakes are located in inaccessible terrain where regular field surveys are difficult.

Key Challenges

• Scientific uncertainty in accurately predicting Glacial Lake Outburst Floods (GLOFs).
• Inadequate assessment of dam stability, geological vulnerabilities, and trigger mechanisms.
• Limited early warning systems and disaster preparedness in high-risk regions.
• Weak coordination among scientific institutions, disaster management agencies, and local communities.

Conclusion

The expansion of high-risk glacial lakes in Arunachal Pradesh highlights the growing intersection between climate change and disaster vulnerability in the Himalayas. While advances in satellite technology have improved hazard detection, the real challenge lies in converting scientific knowledge into effective risk reduction measures. Strengthening preparedness today will be critical to preventing future GLOF disasters in one of the world’s most fragile mountain ecosystems.

UPSC Prelims MCQ

Q. With reference to Glacial Lake Outburst Floods (GLOFs), consider the following statements:
