Key Highlights The concept rooted in prioritizing individual interests over the common good, highlighted by historical philosophers like Aristotle and Thucydides, was later coined by Alfred E. Kahn with the example of the railway system’s shutdown in Ithaca. William Odham extended the concept to environmental issues, emphasizing cumulative impact. Garrett Hardin’s “Tragedy of Commons” warns […]
Key Highlights The Underwater Domain Awareness (UDA) Framework is increasingly necessary for effective sedimentation management. Controlling erosion is one of the best methods to reduce large amounts of sediment. Sediment management in rivers should be the way forward for sustainable management of sediments. Sediment management in rivers should be the way forward for sustainable management […]
Key Highlights China has worked assiduously to change maritime geography through force and cartographic manipulation. This started with its excessive claims in the South China Sea. Monitoring the South China Sea has become necessary for China, the USA, and the regional players, many of whom conflict with China on the issue of the extent of […]
Key Highlights Severe water pollution crisis: India faces significant water pollution issues, with more than 70% of its surface water resources contaminated, leading to approximately 50,000 deaths annually due to waterborne diseases. Economic impact: Poor water quality has extensive economic implications, costing India around 6% of its GDP annually due to public health expenses, reduced […]
Key Highlights Maritime collisions, fueled by surging traffic, pose a grave threat to lives, economies, and ecosystems. Human errors, navigational hazards, and adverse weather are key contributors to these disasters, often resulting in oil spills and extensive environmental damage. The Underwater Domain Awareness (UDA) Framework offers a multi-faceted approach to averting collisions through advanced technologies […]
Key Highlights This article highlights the importance of dredging in India. It talked about Maintenance and Capital dredging. How can the UDA framework help with the issues faced in dredging? How can the UDA framework help with the issues faced in dredging? What is Dredging, and why is it important? Dredging is the underwater excavation […]
Key Highlights Remote sensing technologies are methods for acquiring information about the Earth’s surface and subsurface without direct physical contact. A sub-bottom profiler generates low-frequency sonar waves that penetrate the seafloor, reflecting off various subsurface sediment layers. Continuous refinement of these models can enhance accuracy over time, ensuring more efficient and effective analysis in the […]
Key Highlights The Indian Ocean Region (IOR) has warmed by approximately 1.2°C over the past century, leading to significant changes, including expanding the Indian Ocean Warm Pool (IOWP). Warming has caused higher sea levels and shifts in climate dynamics, potentially disrupting critical rainfall patterns for countries like India. Expanding Oxygen Minimum Zones (OMZs) and declining […]
Key Highlights The global community, under the United Nations (UN) Intergovernmental Ocean Commission (IOC), has prioritised the MSP as a critical tool for enhanced water body management. The Modelling and simulation (M&S)–based MSP, followed by field experimental validation, will revolutionize how we manage the challenges and opportunities of the new global order. The developed nations […]
Key Highlights MSP faces distinct challenges in tropical regions due to sub-optimal sonar performance caused by higher temperatures and varying salinity levels. This hinders accurate mapping and monitoring, necessitating advanced, customised sonar systems. Coastal areas in tropical regions often experience high population densities, leading to intensified pressure on marine resources, including overfishing and pollution, which […]
