A cargo ship discharging ballast water into the sea. Ballast water discharges by ships can have a negative impact on the marine environment. [1] Cruise ships, large tankers, and bulk cargo carriers use a huge amount of ballast water, which is often taken on in the coastal waters in one region after ships discharge wastewater or unload cargo, and discharged at the next port of call, wherever ...
Ports can have a wide environmental impact on local ecologies and waterways, most importantly water quality, which can be caused by dredging, spills and other pollution. Ports are heavily affected by changing environmental factors caused by climate change as most port infrastructure is extremely vulnerable to sea level rise and coastal flooding ...
Among 818 ports in the Pacific region, Singapore alone accounts for an estimated of 26 percent of cross-region (long range) species exchange. Via targeted ballast management on Singapore and a few other "influential" ports, cross-region species exchange to/from the Pacific region can be combinatorially reduced.
As a response, the European Community adopted the Directive 2000/59/EC on port reception facilities with the goal of eliminating discharges of ship-generated residues into the ocean. [4] The Directive is especially aimed at increasing the prevalence and use of port reception facilities , thereby securing a cleaner and more sustainable marine ...
The environmental impact of shipping includes greenhouse gas emissions, acoustic, and oil pollution. [11] The International Maritime Organization (IMO) estimates that Carbon dioxide emissions from shipping were equal to 2.2% of the global human-made emissions in 2012 [12] and expects them to rise 50 to 250 percent by 2050 if no action is taken ...
Congestion at Singapore's container port is at its worst since the COVID-19 pandemic, a sign of how prolonged vessel re-routing to avoid Red Sea attacks has disrupted global ocean shipping - with ...
The Coast Guard carries out a wide range of responsibilities that encompass both homeland security (ports, waterways, and coastal security, defense readiness, drug and migrant interdiction) and non-homeland security (search and rescue, marine environmental protection, fisheries enforcement, aids to navigation).
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
