The Maldives government has chosen not to renew a hydrographic survey agreement with India, marking a significant change in bilateral relations.
Hydrographic Survey Pact: A Backgrounder
Nature of Hydrographic Surveys: These surveys involve mapping water bodies to facilitate safe and efficient maritime transportation.
2019 Agreement: During Prime Minister Modi’s state visit to the Maldives in June 2019, an MoU was signed for cooperation in hydrography between the Indian Navy and the Maldives National Defence Force (MNDF).
Activities under the Pact
Joint Hydrographic Surveys: Three joint surveys were conducted in 2021, 2022, and 2023, involving Indian Naval Ships like INS Darshak and INS Sutlej.
Survey Objectives: The surveys aimed to update navigational charts and support sectors like tourism and fisheries. They also involved tidal observations and identifying new shoals.
Support to MNDF: India provided hydrographic equipment and training to MNDF personnel, aligning with its policy of supporting the Maldives in establishing hydrographic capabilities.
India’s Hydrographic Survey Agreements with Other Countries
Global Hydrographic Efforts: India has conducted hydrographic surveys in various countries, including Sri Lanka, Myanmar, and Bangladesh.
International Cooperation: The National Hydrographic Office highlights the potential for international cooperation in hydrography, especially in regions with limited capabilities.
Reasons behind Maldives’ Decision
Regime Change: The election of Mohamed Muizzu of the Progressive Party of Maldives (PPM), seen as more pro-China, contrasts with his predecessor President Solih’s India-friendly stance.
Geopolitical Dynamics: China’s increasing influence in the Indian Ocean region, particularly through the Belt and Road Initiative (BRI), has impacted India’s traditional sphere of influence in the Maldives.
‘India Out’ Campaign: Allegations of Indian military presence and the new administration’s emphasis on national security and self-reliance in hydrographic capabilities have influenced this decision.
Possible outcomes
Changing Geopolitical Landscape: The Maldives’ decision reflects the shifting geopolitical dynamics in the Indian Ocean, with growing Chinese influence challenging India’s traditional role.
Impact on India-Maldives Relations: This development could signify a recalibration of the Maldives’ foreign policy, potentially impacting India’s strategic interests in the region.
Unprecedented Warmth: The Arctic experienced its warmest summer on record in 2023, warming nearly four times faster than the global average since 1979.
NOAA’s Comprehensive Study: The National Oceanic and Atmospheric Administration’s (NOAA) Arctic Report Card, a peer-reviewed analysis by 82 scientists from 13 countries, details the critical impacts of this warming.
Key Findings and Consequences of the Arctic Warming
[1] Thawing of Subsea Permafrost
Accelerated Thawing Process: Warmer ocean temperatures are causing a faster thawing of subsea permafrost, which contains organic matter.
Release of Greenhouse Gases: This thawing leads to the decay of organic matter and the release of methane and carbon dioxide, intensifying global warming and ocean acidification.
Research Challenges: The extent of greenhouse gas release from subsea permafrost and its future impact on global warming remains uncertain due to limited research.
[2] Food Insecurity
Decline in Salmon Populations: In Western Alaska, populations of Chinook and chum salmon were 81% and 92% below the 30-year mean, respectively.
Size Reduction and Species Variation: The size of adult salmon has decreased, and while Chinook and chum salmon declined, sockeye salmon numbers were 98% above the 30-year mean.
Impact on Indigenous Communities: These changes have led to fishery closures and significant cultural and food security impacts in Indigenous communities.
[3] Raging Wildfires
Canada’s Severe Wildfire Season: Canada experienced its worst wildfire season, with over 10 million acres burned in the Northwest Territories.
Evacuations and Air Quality Impact: The fires led to mass evacuations and affected air quality, reaching as far as the southern United States.
[4] Severe Flooding
Mendenhall Glacier Thinning: The Mendenhall Glacier in Alaska has thinned dramatically, causing annual floods.
Significant Flooding Event: In August 2023, a glacial lake burst through its ice dam, leading to unprecedented flooding and severe property damage in Juneau.
[5] Greenland Ice Sheet Melting
Rare Melting Events: The highest point on Greenland’s ice sheet experienced melting for only the fifth time in 34 years.
Continued Mass Loss: Despite above-average winter snow accumulation, the ice sheet lost approximately 350 trillion pounds of mass between August 2022 and September 2023.
Contribution to Sea-Level Rise: Greenland’s ice sheet melting is the second-largest contributor to global sea-level rise.
Conclusion
Immediate and Long-Term Impacts: The record-breaking temperatures in the Arctic have immediate consequences for local communities and long-term implications for global climate patterns.
Need for Further Research: Enhanced research is crucial to understand the full scope of Arctic warming and to develop effective mitigation strategies.
Global Responsibility: The findings highlight the urgent need for concerted global efforts to address climate change and its far-reaching impacts.
