Why in news : India is witnessing a significant evolution in climate governance as states transition from generic, top-down State Action Plans on Climate Change (SAPCCs) to localized, data-driven strategies like the Urban Heat Island (UHI) mitigation efforts.  

About : 

Climate change is increasingly emerging as a local governance challenge rather than merely a global environmental concern. India has witnessed a sharp rise in climate-induced risks such as heatwaves, urban flooding, water scarcity, and air pollution, particularly in rapidly growing cities. Between 1901 and 2023, India's average temperature increased by nearly 0.7°C, while several cities recorded temperatures above 48°C in recent years. Urban areas often experience temperatures 3–8°C higher than surrounding rural regions due to the Urban Heat Island (UHI) effect, exacerbating health and productivity losses. Traditionally, climate action was guided by broad State Action Plans on Climate Change (SAPCCs), which adopted a state-wide approach. However, the uneven spatial distribution of climate impacts has highlighted the need for localized, data-driven interventions. Consequently, India is transitioning towards city-specific climate governance, exemplified by Urban Heat Island mitigation and climate-resilient urban planning initiatives. 

Evolution of Climate Governance in India

A. First Generation Climate Governance

India's initial climate governance architecture was largely top-down and sector-oriented, focusing on integrating climate concerns into state and national development planning.

• National Action Plan on Climate Change (NAPCC), 2008: Established eight national missions covering solar energy, water conservation, sustainable agriculture, energy efficiency, and ecosystem protection.
• State Action Plans on Climate Change (SAPCCs): States prepared climate strategies aligned with local vulnerabilities and development priorities.

Sectoral Focus

• Agriculture: Climate-resilient crops, drought management (e.g., promotion of millets in Rajasthan).
• Water: Watershed development and groundwater conservation (e.g., Jalyukt Shivar in Maharashtra).
• Energy: Expansion of renewable energy capacity (e.g., Gujarat's solar parks).
• Forestry: Afforestation and carbon sink creation (e.g., Green India Mission).
• Disaster Management: Cyclone preparedness and early warning systems (e.g., Odisha's cyclone management model).

B. Limitations of SAPCCs

While SAPCCs mainstreamed climate concerns, several implementation gaps emerged:

• Broad and generic recommendations: Similar strategies were adopted across states despite differing local conditions.
• Limited city-level implementation: Urban-specific risks often remained outside planning frameworks.
• Weak local data integration: Lack of ward-level climate vulnerability assessments.
• Insufficient monitoring mechanisms: Difficulty in tracking outcomes and measuring effectiveness.
• Neglect of urban climate risks: Issues such as Urban Heat Islands, urban flooding, and heat stress received limited attention.

Example: Despite having SAPCCs, cities like Delhi, Ahmedabad, and Hyderabad experienced recurrent heatwaves and localized climate stresses, prompting the development of dedicated Heat Action Plans and city-specific climate strategies beyond traditional state-level frameworks.

Why is Localized Climate Governance Emerging?

A. Growing Urban Vulnerability

1. Urban Heat Waves

• Indian cities are experiencing more frequent and prolonged heatwaves due to climate change and Urban Heat Island effects.
• Heatwaves have become one of India's deadliest weather hazards, affecting public health and urban livability.

Example: In May 2024, Delhi recorded temperatures above 49°C, while parts of Rajasthan crossed 50°C, causing severe heat stress and disruptions to daily life.

2. Rapid Urbanization

• Expansion of roads, buildings, and paved surfaces increases heat absorption and reduces natural cooling.
• Urban growth often occurs at the expense of green spaces, water bodies, and wetlands.

Example: Bengaluru lost a significant proportion of its lakes and green cover over recent decades, contributing to rising urban temperatures and flooding incidents.

3. Climate Justice Concerns

• Climate impacts are not evenly distributed; low-income groups face greater exposure and lower adaptive capacity.
• Slum residents, street vendors, construction workers, delivery personnel, and the elderly are particularly vulnerable.

Example: During extreme heat events, outdoor workers in cities such as Ahmedabad and Delhi face reduced working hours, income losses, and higher health risks.

4. Rising Economic Costs

• Extreme heat lowers labour productivity, increases electricity demand, and raises healthcare expenditures.
• Urban economies become increasingly vulnerable to climate-induced disruptions.

Example: According to estimates by the International Labour Organization (ILO), heat stress could lead to the loss of millions of working hours annually in India, particularly in construction and agricultural sectors. Simultaneously, electricity demand in major cities spikes sharply during heatwaves due to increased air-conditioning and cooling needs.

Urban Heat Island (UHI): A New Frontier in Climate Governance

What is Urban Heat Island (UHI)?

Urban Heat Island (UHI) refers to the phenomenon whereby urban areas record significantly higher temperatures than their surrounding rural regions. This occurs because cities replace natural landscapes with heat-absorbing surfaces and generate large amounts of waste heat.

Key Drivers

• Concrete structures and buildings absorb and retain solar heat during the day and release it slowly at night.
• Asphalt roads can attain surface temperatures exceeding 50–60°C during summer.
• Reduced vegetation lowers evapotranspiration, diminishing the natural cooling effect.
• Anthropogenic heat emissions from vehicles, industries, air-conditioners, and power consumption further elevate urban temperatures.

Example: Studies in Delhi, Hyderabad, and Ahmedabad have documented urban temperatures 3–8°C higher than nearby rural areas during peak summer conditions.

Features of New-Age Climate Governance

Unlike earlier climate policies that relied on broad state-level assessments, the new generation of climate governance is localized, technology-enabled, and implementation-oriented, focusing on micro-level vulnerabilities and targeted interventions.

1. Data-Driven Planning

Climate decisions are increasingly guided by high-resolution spatial and climatic data rather than generalized projections.

• Satellite imagery, GIS mapping, and remote sensing help identify heat hotspots, flood-prone zones, and shrinking green spaces.
• Hyper-local temperature monitoring enables city authorities to target the most vulnerable neighbourhoods.

Example: Ahmedabad and Delhi have used satellite-based heat mapping to identify areas experiencing severe Urban Heat Island effects. Under the Smart Cities Mission, GIS platforms are increasingly being integrated into urban planning.

2. Decentralized Governance

Climate action is shifting from state governments to city administrations and local institutions that better understand local risks.

• Municipal corporations and Urban Local Bodies (ULBs) are becoming key actors in climate adaptation.
• Ward-level planning allows interventions tailored to neighbourhood-specific vulnerabilities.

Example: Ahmedabad Municipal Corporation pioneered India's first Heat Action Plan (2013), demonstrating how city-level institutions can lead climate adaptation measures.

3. Evidence-Based Interventions

Policies are now based on scientific assessments rather than broad assumptions.

• Heat mapping identifies high-temperature zones.
• Vulnerability assessments locate populations most at risk.
• Risk zoning guides infrastructure and land-use decisions.

Example: Telangana's cool-roof initiatives targeted low-income settlements identified through vulnerability assessments, helping reduce indoor temperatures by approximately 2–5°C.

4. Integration Across Sectors

Climate governance is increasingly embedded within urban development and public service delivery.

• Urban Planning: Expansion of green spaces and climate-resilient infrastructure.
• Public Health: Heat warning systems and cooling centres.
• Water Management: Restoration of urban lakes and wetlands.
• Energy Efficiency: Promotion of cool roofs and energy-efficient buildings.

Example: Hyderabad's Heat Action Plan combines public health advisories, urban greening, water access measures, and heat-risk monitoring, illustrating a multi-sectoral approach to climate resilience.

Case Study: Ahmedabad Heat Action Plan (AHAP) – A Pioneer in Localized Climate Governance

The Ahmedabad Heat Action Plan (AHAP), launched in 2013, is widely regarded as South Asia's first city-level Heat Action Plan and a landmark example of localized climate governance. It was developed following the devastating 2010 heatwave, during which Ahmedabad experienced temperatures exceeding 46°C, leading to a significant rise in heat-related illnesses and deaths.

Key Interventions

• Early Warning System: Collaboration between the India Meteorological Department (IMD) and city authorities to issue heat alerts several days in advance.
• Public Awareness Campaigns: Dissemination of heat-safety guidelines through SMS, media, schools, and community outreach.
• Healthcare Preparedness: Training of doctors and hospital staff to identify and treat heat-related illnesses.
• Protection of Vulnerable Groups: Special focus on outdoor workers, slum residents, children, and the elderly.

Outcomes

• Studies indicate that the plan contributed to a substantial reduction in heat-related mortality, particularly during extreme heat events.
• The Ahmedabad model has inspired similar Heat Action Plans in more than 20 Indian states and numerous cities, including Delhi, Bhubaneswar, Nagpur, and Hyderabad.

Challenges in the Transition to Localized Climate Governance

1. Institutional Challenges

Despite growing climate risks, many Urban Local Bodies (ULBs) lack the technical expertise, manpower, and institutional capacity needed for climate planning and implementation.

• Climate governance often remains an additional responsibility rather than a dedicated function.
• Coordination between municipal bodies, development authorities, state departments, and disaster management agencies remains weak.

Example: Many Indian cities still lack dedicated climate cells, making implementation of Heat Action Plans and resilience projects dependent on external agencies and consultants.

2. Financial Constraints

Localized climate adaptation requires substantial investments in green infrastructure, cooling systems, urban forests, and climate-resilient services.

• Most ULBs have limited own-source revenues.
• Climate projects largely depend on state government support, central schemes, or international funding.

Fact: Municipal bodies in India account for only a small share of total public expenditure compared to cities in developed countries, constraining their ability to undertake large-scale climate interventions.

Example: Projects such as urban wetland restoration and cool-roof programmes often rely on Smart Cities Mission or externally funded initiatives rather than municipal budgets.

3. Data Challenges

Effective localized governance depends on accurate and granular climate information, which remains inadequate in many cities.

• Lack of ward-level climate and vulnerability data.
• Multiple agencies maintain separate datasets, resulting in fragmented information systems.

Example: While cities like Ahmedabad and Delhi have developed heat-vulnerability maps, many Tier-II and Tier-III cities still lack high-resolution temperature, flood-risk, and exposure databases required for evidence-based planning.

4. Governance Challenges

Climate concerns are often poorly integrated into urban development decisions.

• Master Plans frequently prioritize infrastructure expansion without adequately accounting for climate risks.
• Political leadership tends to focus on projects with immediate visible outcomes, whereas climate adaptation yields benefits over longer periods.

Example: Continued construction on urban floodplains and wetland areas in cities such as Bengaluru and Chennai has increased vulnerability to flooding despite repeated climate-related disasters.

Future Roadmap for Localized Climate Governance 

1. Institutionalize Urban Climate Cells

Dedicated climate units should be established within municipal corporations for planning, monitoring, and coordination.

Example: Several Smart Cities have begun setting up climate and sustainability offices, but wider institutionalization remains necessary.

2. Mainstream Climate Considerations into Master Plans

Urban development plans should integrate heat, flood, and water-risk assessments before approving infrastructure projects.

Example: Chennai's post-2015 flood planning increasingly emphasizes floodplain protection and climate-sensitive urban development.

3. Strengthen Municipal Finances

Cities require predictable financial resources to invest in resilience infrastructure.

Fact: Urban India may require hundreds of billions of dollars in climate-resilient infrastructure investments by mid-century, far exceeding current municipal capacities.

4. Expand Green-Blue Infrastructure

Protecting and restoring parks, urban forests, lakes, rivers, and wetlands can simultaneously address heat, flooding, and biodiversity loss.

Example: Restoration of urban lakes in Bengaluru and wetland conservation initiatives in Kolkata have demonstrated multiple climate resilience benefits.

5. Develop Local Climate Data Repositories

Cities should establish integrated databases combining climate, health, infrastructure, and socioeconomic information for evidence-based decision-making.

Example: Ahmedabad's heat-risk mapping and IMD-supported early warning systems illustrate how localized datasets can improve climate preparedness.

What are Solar Storms?

Solar storms are disturbances in space caused by intense activity on the Sun, leading to the release of enormous amounts of energy, radiation, and charged particles into space. They are a major component of space weather and can influence Earth's atmosphere, satellites, communication systems, navigation networks, and power grids.

Why Do Solar Storms Occur?

The Sun is composed of hot plasma and possesses a highly dynamic magnetic field. Twisting, tangling, and reconnection of magnetic field lines release massive amounts of energy, generating solar storms.

Main Sources

• Sunspots
• Magnetic reconnection
• Solar magnetic cycles (approximately 11 years)

Example: Solar activity generally peaks during the Solar Maximum, the most active phase of the Sun's 11-year cycle.

Types of Solar Storms

1. Solar Flares

Sudden bursts of electromagnetic radiation from the Sun's surface.

Characteristics

• Travel at the speed of light.
• Reach Earth within about 8 minutes.
• Affect radio communications and GPS systems.

Example

In May 2024, powerful X-class solar flares disrupted high-frequency radio communications in some regions.

2. Coronal Mass Ejections (CMEs)

Massive clouds of plasma and magnetic fields ejected from the Sun.

Characteristics

• Travel at 250–3000 km/s.
• Take 1–3 days to reach Earth.
• Can trigger geomagnetic storms.

Example

The 1859 Carrington Event remains the strongest recorded CME impact on Earth.

3. Solar Energetic Particle (SEP) Events

Streams of highly energetic protons and ions accelerated by solar eruptions.

Impacts

• Radiation hazard for astronauts.
• Risk to aircraft flying polar routes.
• Satellite damage.

Example

Airlines sometimes alter polar flight paths during intense SEP events.

4. Geomagnetic Storms

Occur when solar particles interact with Earth's magnetosphere.

Effects

• Auroras
• Power grid disturbances
• Satellite anomalies

Example

The March 1989 geomagnetic storm caused a province-wide blackout in Quebec.

Visibility of Solar Storms

Solar storms themselves are invisible, but their effects can be seen through auroras.

Aurora Borealis (Northern Lights)

Visible in:

• Norway
• Iceland
• Canada
• Finland
• Alaska

Aurora Australis (Southern Lights)

Visible in:

• New Zealand
• Australia
• Antarctica

Solar Storms and India

India is becoming increasingly vulnerable because of:

• Expanding satellite constellation programmes.
• Growth of digital infrastructure.
• Dependence on GNSS navigation.
• Human spaceflight missions such as Gaganyaan.

Solar storms are invisible cosmic hazards that transform activity on the Sun into tangible economic, technological, and geopolitical impacts on Earth, making space weather forecasting as important in the 21st century as terrestrial weather forecasting.

Coal gasification: Coal gasification is a process in which coal is converted into a combustible gas mixture called syngas (mainly carbon monoxide, hydrogen, and methane) by reacting it with oxygen, steam, or air under high temperatures and controlled conditions. Syngas can be used for electricity generation, production of fertilizers, chemicals, methanol, and hydrogen. It is considered a cleaner alternative to direct coal combustion because pollutants can be removed before utilization, although it still involves significant carbon emissions unless coupled with carbon capture technologies.

Flue gas desulphurisation: Flue Gas Desulphurisation (FGD) is a pollution-control technology used in thermal power plants and industries to remove sulphur dioxide (SO₂) from exhaust gases before their release into the atmosphere. The most common method uses limestone or lime slurry, which reacts with SO₂ to produce gypsum. FGD helps reduce acid rain, respiratory illnesses, and environmental degradation. In India, installation of FGD systems has become important for coal-based power plants to meet stricter emission standards and improve air quality.

Common But differentiated Responsibilities: Common But Differentiated Responsibilities (CBDR) is a principle of international environmental law recognized in the 1992 United Nations Conference on Environment and Development. It states that all countries share responsibility for addressing global environmental problems, but developed countries should bear a greater burden because of their historical contribution to environmental degradation and their greater financial and technological capabilities. CBDR forms a key foundation of global climate negotiations, including the Paris Agreement.

Exfiltration: Exfiltration refers to the unauthorized transfer or extraction of sensitive data from a computer system, network, or organization by cybercriminals, insiders, or malware. It is often the final stage of a cyberattack after gaining access to a system. Stolen information may include personal records, financial data, intellectual property, or government secrets. Exfiltration can occur through emails, cloud services, removable devices, or encrypted channels. Preventive measures include encryption, access controls, network monitoring, and robust cybersecurity frameworks.

Isostatic Rebound: Isostatic rebound, also called post-glacial rebound, is the gradual rise of Earth's crust after the removal of a heavy load such as a massive ice sheet. During glacial periods, the weight of ice depresses the lithosphere into the underlying mantle. When the ice melts, the crust slowly uplifts to regain equilibrium according to the principle of isostasy. This process continues for thousands of years and is evident in regions such as Canada and Sweden, where land is still rising following the last Ice Age.

The Konkan Railway (760 km), connecting Maharashtra, Goa, and Karnataka, is a classic example of applied geomorphology in infrastructure planning. The route traverses the rugged Western Ghats, characterized by steep slopes, lateritic plateaus, deeply incised valleys, and landslide-prone terrain. Detailed geomorphological mapping was used to identify stable rock formations, slope gradients, drainage patterns, and areas susceptible to mass wasting.

As a result, engineers constructed 92 tunnels and over 2,000 bridges, avoiding highly unstable landforms. Slope stabilization measures, rock bolting, and improved drainage systems were incorporated to reduce landslide risks. The project significantly improved connectivity along India's western coast while minimizing geomorphic hazards.

The Konkan Railway demonstrates how geomorphological knowledge can enhance the safety, sustainability, and economic viability of large-scale infrastructure projects in complex terrains.
