Part 1: Climate vulnerability assessment - who is most at risk?

20 minutes

Understanding vulnerability

IPCC framing: In AR4 (2007), vulnerability depends on exposure, sensitivity and adaptive capacity. Since AR5 (2014), exposure is treated separately. Risk arises from hazard, exposure and vulnerability, and vulnerability means sensitivity plus lack of capacity to cope and adapt

  • Exposure: Degree to which a system is in contact with climate hazards
  • Sensitivity: Degree to which a system is affected by climate stimuli
  • Adaptive Capacity: Ability to adjust to potential damages or cope with consequences

Vulnerability patterns in South Asia

Geographic hotspots
  • Coastal Areas: Sea level rise, cyclones, salt intrusion
  • Gangetic Plains: Flooding, heat waves, groundwater depletion
  • Western Ghats: Extreme rainfall, landslides
  • Himalayan Region: Glacial melt, flash floods
  • Arid/Semi-Arid: Droughts, desertification, heat stress
Social vulnerability
  • Women: Higher exposure during extreme events, limited mobility
  • Children & Elderly: Health sensitivity to heat, vector-borne diseases
  • Indigenous Communities: Land-dependent livelihoods, limited access to services
  • Urban Poor: Informal settlements in risk-prone areas
  • Smallholder Farmers: Climate-dependent incomes, limited resources
  • Outdoor and Industrial Workers: Heat stress at work, physical labour, little workplace protection

Case study: Sundarbans vulnerability

Location: Indian Sundarbans, the West Bengal part of the mangrove delta shared with Bangladesh

Population: About 4.4 million people (Census 2011) in 19 blocks, living on 54 islands; the rest of the delta is reserve forest (Department of Sundarban Affairs, West Bengal)

Vulnerability Factor Current Status Climate Projections Implication
Exposure Rising sea level, erosion and cyclones Further sea-level rise and more intense cyclones Island submersion, displacement
Sensitivity Most households depend on agriculture, aquaculture and forest produce Saltwater intrusion increases Crop failure, livelihood loss
Adaptive Capacity Limited infrastructure, high poverty Out-migration accelerates High overall vulnerability

Vulnerability mapping exercise (8 minutes)

Choose one context:

Option A: Urban slum in Chennai
  • Coastal location, monsoon flooding
  • Informal settlements, poor drainage
  • Daily wage laborers, migrant families
  • Limited access to health services
Option B: Tribal village in Jharkhand
  • Forest-dependent livelihoods
  • Rainfed agriculture, irregular monsoons
  • Remote location, limited connectivity
  • Traditional knowledge systems

Assessment Framework (5 minutes): Rate each factor (1-5 scale, 5 = highest risk)

  • Climate Exposure: What hazards face this community? How severe?
  • Economic Sensitivity: How climate-dependent are livelihoods?
  • Social Sensitivity: Which groups face additional risks?
  • Adaptive Capacity: What resources exist for coping/adapting?

Sharing (3 minutes): Present vulnerability score and top 2 risk factors

Part 2: Adaptation strategies - building resilience

20 minutes

Adaptation Definition: Adjustments in ecological, social, or economic systems in response to actual or expected climatic stimuli and their effects, which moderates harm or exploits beneficial opportunities.

Types of adaptation approaches

Ecosystem-based adaptation

Principle: Use biodiversity and ecosystem services to help people adapt

Indian Examples:

  • Mangrove Restoration: Sundarbans, Gujarat coast for storm protection
  • Watershed Management: Rajasthan's water harvesting systems
  • Urban Green Infrastructure: Sponge cities, green roofs in Pune
  • Coral Reef Conservation: Lakshadweep, Andaman islands

Infrastructure-based adaptation

Principle: Build physical systems to reduce climate risks

Indian Examples:

  • Early Warning Systems: Cyclone tracking, heat wave alerts
  • Climate-Resilient Housing: Disaster-resistant construction
  • Flood Management: Chennai's flood control systems
  • Drought-Proofing: Drip irrigation, water storage

Community-based adaptation

Principle: Build local capacity and use traditional knowledge

Indian Examples:

  • Climate-Smart Agriculture: SRI rice cultivation, crop diversification
  • Traditional Water Management: Tank systems in Tamil Nadu
  • Livelihood Diversification: Agriculture + aquaculture + livestock
  • Community Seed Banks: Preserving climate-resilient varieties

Policy-based adaptation

Principle: Create enabling environments for adaptation

Indian Examples:

  • National Action Plan on Climate Change (NAPCC): 8 national missions
  • State Action Plans: Context-specific strategies
  • Climate Risk Insurance: Weather-based crop insurance
  • Disaster Management Acts: Legal frameworks for resilience

Example: Maharashtra's project on climate resilient agriculture (PoCRA)

Challenge: Recurring drought and soil salinity in Marathwada and Vidarbha

Intervention: Integrated approach combining multiple adaptation strategies

Key Components:

  • Water Security: Watershed treatment, check dams, farm ponds
  • Climate-Smart Agriculture: Drought-tolerant seeds, drip irrigation
  • Livelihood Diversification: Dairy, poultry, kitchen gardens
  • Institutional Strengthening: Village climate committees, weather-based advisories

Scale: Launched in 2018 with a US$420 million World Bank loan for about 5,000 villages in 15 districts; a second phase was approved in 2025. Read the project's own evaluation reports for results.

  • Climate-Smart Agriculture: Crop insurance, climate-resilient varieties
  • Disaster Risk Reduction: Early warning, infrastructure hardening
  • Ecosystem Services: Coastal protection, urban green spaces

India's mitigation efforts

Energy sector transformation

Current Status: 184.6 GW of renewable capacity (excluding large hydro) and 242.8 GW of non-fossil capacity by 30 June 2025, half of installed capacity (Ministry of New and Renewable Energy)

Targets: 500 GW non-fossil capacity by 2030 (announced at COP26), Net Zero by 2070

Key Initiatives:

  • Solar Mission: 100 GW solar target for 2022 (missed then); about 116 GW installed by June 2025
  • Wind Power: About 52 GW installed by June 2025; offshore wind still at the tender stage
  • Green Hydrogen: National mission for clean fuel production

Part 4: Climate justice - ensuring equitable action

25 minutes

Climate justice principles

Distributive Justice: Fair distribution of benefits and burdens of climate action

Procedural Justice: Meaningful participation in climate decision-making

Recognition Justice: Acknowledgment of different values, knowledge systems, and rights

Corrective Justice: Accountability for climate harms and appropriate remedies

Climate justice lens

The Paradox: Those who contribute least to climate change suffer the most from its impacts

Group Contribution to Emissions Climate Impact Level Access to Solutions
World's poorest 50% Very low (7% of cumulative emissions, 1990-2015; Oxfam and SEI, 2020) Very high Very limited
World's middle 40% Medium (41%) Medium Moderate
World's richest 10% Very high (52%) Low High

Governance challenges & opportunities

Multi-level climate governance

Global Level: Paris Agreement, climate finance, technology transfer

National Level: NDCs, climate laws, sectoral policies

State Level: Climate action plans, adaptation strategies

Local Level: Urban climate plans, community adaptation

Challenge: Coordination across levels and alignment of incentives

Climate finance and equity

The Numbers:

  • Global Need: About $2.4 trillion/year by 2030 for emerging and developing economies other than China (Independent High-Level Expert Group on Climate Finance, 2022)
  • Developing Country Need: $215-387 billion/year for adaptation this decade (UNEP Adaptation Gap Report 2023)
  • Current Finance: The $100 billion/year goal is being replaced by at least $300 billion/year by 2035 (COP29, 2024), still far below need
  • India's Requirement: At least $2.5 trillion (2014-15 prices) for 2015-2030 (India's first NDC, 2015)

Equity Concerns:

  • Developed countries produced 79% of carbon emissions from 1850 to 2011 (Center for Global Development, 2015)
  • Climate finance often comes as loans, not grants
  • Adaptation receives less funding than mitigation
  • Local communities often excluded from decision-making

Justice challenges in Indian climate action

Renewable energy projects

Benefits: Clean energy, reduced emissions

Justice Concerns:

  • Land acquisition affects farming communities
  • Benefits accrue to urban consumers
  • Limited local employment generation
  • Inadequate consultation processes
Forest conservation

Benefits: Carbon sequestration, biodiversity

Justice Concerns:

  • Restrictions on traditional forest use
  • Limited recognition of forest rights
  • Displacement of indigenous communities
  • Top-down conservation approaches

Climate justice analysis (10 minutes)

Case Study: Large-scale solar park development in Rajasthan

Project Details: 5,000 hectares of agricultural land acquired for 750 MW solar park

Benefits: Clean energy generation, reduced coal dependence, state revenue

Costs: 2,000 farming families displaced, loss of traditional livelihoods, cultural disruption

Justice Assessment Framework (6 minutes):

  1. Distributive Justice: Who bears the costs vs. who receives the benefits? Is this fair?
  2. Procedural Justice: Were affected communities meaningfully consulted? Did they have decision-making power?
  3. Recognition Justice: Were traditional land rights and farming knowledge valued? Cultural impacts considered?
  4. Corrective Justice: What compensation was provided? Are there grievance mechanisms?

Redesign Challenge (4 minutes): How could this project be redesigned to be more just? What alternative approaches exist?

Principles for just climate action

  • Free, Prior, Informed Consent: Real community participation in all phases
  • Benefit Sharing: Local communities receive fair share of project benefits
  • Cultural Sensitivity: Respect for traditional knowledge and practices
  • Adaptive Management: Flexibility to address emerging concerns
  • Accountability Mechanisms: Independent monitoring and grievance systems
