UN Declaration on Rising Sea Levels

Summary Notes on Rising Sea Levels and UN Declaration

International Agreements and UN Declaration

• UN General Assembly Declaration: Adopted on 24 September 2026, it is the first global formal recognition of the implications of rising sea levels on statehood and territorial integrity.
• Key Provisions:
  • Recognizes that countries losing territory due to rising sea levels can retain sovereignty and rights.
  • Emphasizes the importance of incorporating sea-level rise projections into coastal infrastructure planning.
  • Calls for enhanced international cooperation to assist populations displaced by climate change.

Facts and Figures on Sea Level Rise

• Acceleration of Sea Level Rise:
  • Rise increased from 2.1 mm/year (1993-2002) to 4.7 mm/year (2015-2024).
  • 2024 recorded a historic increase of 6 mm.
• Future Projections:
  • Under low-emission scenarios, sea levels expected to rise by 38 cm by 2100.
  • In high-emission scenarios, the figure could reach 77 cm.

Legal Framework

• Montevideo Convention (1933): Defines the criteria for statehood: permanent population, defined territory, governance, and capacity for international relations.
• Territorial Integrity: Countries affected by rising sea levels will maintain their maritime boundaries, which include 12 nautical miles for territorial seas and up to 370 km for exclusive economic zones.

Human Rights and Migration Policies

• Countries are urged to respect human rights for displaced persons and facilitate "mobility with dignity".
• As of December 2025, over a third of Tuvalu’s population applied for climate visas to Australia under a bilateral agreement.

India's Context

• Geographical Data:
  • India has 1,298 coastal islands and a coastline of 11,098 km.
  • Concerns over erosion: One-third of the mainland coastline assessed between 1990-2016 found significant erosion, with regions losing 5 meters a year.
• Coastal Regulation:
  • 2019 Coastal Regulation Zone notification: 50 meters no-build zone in populated areas, 200 meters in others.
  • The necessity for India to adapt these guidelines using updated hazard lines for disaster management.

Economic Indicators

• Adaptation Funding: UN Environment Programme estimates over $310 billion per year needed for developing countries’ adaptation by 2035, contrasting sharply with only $26 billion in 2023.
• Previous objections by India regarding inadequate climate finance targets highlight the ongoing financial gap for effective adaptation strategies.

Future Actions Recommended for India

• Implementation of laws addressing gradual land loss and displacement, akin to Fiji’s planned relocation strategy.
• Immediate action required to measure no-build zones from hazard lines and enforce regulations based on local erosion rates.
• Commitment to advocating for increased climate financing in upcoming global forums, including COP31 in Antalya.

Timeline for Action

• Next high-level UN meeting on sea level rise scheduled for September 2030, presenting a four-year window for implementing necessary policies and reforms.

In conclusion, the UN declaration aims to safeguard statehood against the backdrop of climate change, pressing nations to enhance their infrastructure resilience and establish humanitarian policies for displaced communities. India, as a key player with extensive coastlines, faces critical challenges and responsibilities in this endeavor.
