Introduction to the Groundswell Report

The World Bank Groundswell Report released in 2023 projects that by 2050, approximately 216 million people globally could be internally displaced due to climate change impacts. The report focuses on six regions, identifying Sub-Saharan Africa as the most affected with an estimated 86 million internal climate migrants, followed by East Asia and the Pacific (49 million) and South Asia (40 million). These figures highlight an unprecedented scale of climate-induced internal migration that will strain governance, economic systems, and social infrastructure.

Climate-Induced Internal Migration: Regional and Economic Dimensions

The Groundswell Report quantifies internal climate migration driven by deteriorating agricultural productivity, water scarcity, and extreme weather events. Sub-Saharan Africa’s 86 million migrants reflect acute vulnerability due to reliance on rain-fed agriculture and weak adaptive capacity. South Asia’s 40 million projected migrants, including India, face similar risks exacerbated by monsoon variability and heat stress.

• India’s internal migration population stood at over 450 million as per Census 2011, with climate stress expected to increase displacement within rural and urban areas.
• IPCC AR6 (2023) estimates up to a 30% decline in agricultural productivity in vulnerable regions by 2050, directly impacting livelihoods and triggering migration.
• Economic costs include increased urban infrastructure demand, loss of agricultural output, and potential GDP losses of 2-4% in affected countries (World Bank estimates).
• India allocates ₹3,000 crore annually for disaster management (Union Budget 2023-24), but lacks dedicated funding for climate migration adaptation.

Legal and Constitutional Frameworks Relevant to Climate Migration in India

India’s constitutional and legal provisions provide partial safeguards for climate migrants but lack a comprehensive framework. Article 21 guarantees the right to life and personal liberty, which courts have interpreted to encompass environmental rights and displacement issues. The Disaster Management Act, 2005 (Sections 6 and 10) mandates preparedness and response to disasters, including climate events, but does not explicitly address migration.

• The Environment Protection Act, 1986 regulates environmental degradation but lacks provisions for displacement or migration.
• The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 governs migrant labor but does not recognize climate migrants, creating a policy gap.
• Internationally, the UNFCCC Paris Agreement (2015) emphasizes climate adaptation and loss and damage mechanisms, which are relevant to migration but lack enforceable migration-specific commitments.

Institutional Roles in Addressing Climate Migration

Multiple institutions operate in overlapping domains of climate adaptation, disaster response, and migration governance, leading to fragmented policy implementation.

• The World Bank produces analytical reports and finances climate adaptation projects globally.
• The United Nations Framework Convention on Climate Change (UNFCCC) oversees international climate agreements, including adaptation finance and loss and damage discussions.
• India’s Ministry of Environment, Forest and Climate Change (MoEFCC) formulates national climate policies.
• The National Disaster Management Authority (NDMA) is responsible for disaster preparedness and response.
• The International Organization for Migration (IOM) works on migration governance, including climate migration frameworks.
• The Ministry of Labour and Employment regulates migrant labor but lacks specific provisions for climate-induced migrants.

Policy Gaps and Challenges in India

India’s lack of a dedicated legal framework for climate-induced internal migration results in policy fragmentation and inadequate protection for migrants. Disaster management focuses on immediate response rather than long-term migration adaptation. Labor laws do not recognize climate migrants, leaving them vulnerable to exploitation. Urban planning does not integrate climate migration trends, exacerbating infrastructure and social service pressures.

• Absence of a unified national policy on climate migration obstructs coordinated action.
• Limited data on climate-induced displacement hampers targeted interventions.
• Financial resources are insufficient and not earmarked for migration-related adaptation.
• Legal ambiguity around rights and entitlements of climate migrants persists.

Significance and Way Forward

The Groundswell Report’s projections necessitate urgent policy integration of climate change and migration. India must develop a comprehensive legal framework recognizing climate migrants and their rights under Article 21. Coordination between the MoEFCC, NDMA, Ministry of Labour, and urban development ministries is critical. Dedicated funding for climate migration adaptation should be institutionalized within disaster management budgets. Strengthening data collection and early warning systems will enable proactive migration management.

• Formulate a national climate migration policy aligned with international frameworks like the UNFCCC.
• Integrate migration considerations into climate adaptation and urban planning strategies.
• Enhance institutional coordination and capacity building across relevant ministries.
• Allocate dedicated financial resources for climate migration adaptation and resilience.
• Promote community-based adaptation and livelihood diversification to reduce forced displacement.
