Oceans & Seas

Oceans and seas play a vital role in the context of Sustainable Development Goals (SDGs) as they significantly contribute to the Earth's biosphere's health and the global economy. They are critical to sustaining life on earth, acting as a major source of food and oxygen while also serving as natural carbon sinks that mitigate climate change impacts. SDG 14, "Life Below Water," explicitly acknowledges the importance of conservation and the sustainable use of the world's oceans, seas, and marine resources.

Oceans absorb about 30% of carbon dioxide produced by humans, buffering the impacts of global warming. However, this process has implications such as ocean acidification, negatively impacting marine biodiversity and ecosystems. These impacts, coupled with unsustainable fishing practices and pollution, threaten the health of our oceans and seas. SDG 14 sets targets to prevent and reduce marine pollution of all kinds, sustainably manage and protect marine and coastal ecosystems, and regulate harvesting and end overfishing to restore fish stocks to sustainable levels.

Oceans also support economic wellbeing. Over three billion people depend on marine and coastal biodiversity for their livelihoods. By protecting oceanic ecosystems, the SDGs also support SDG 1, "No Poverty," and SDG 8, "Decent Work and Economic Growth." Furthermore, the oceanic routes are critical for global trade, supporting SDG 9, "Industry, Innovation, and Infrastructure."

Furthermore, by implementing strategies for cleaner and more sustainable use of oceans and seas, it can also contribute to SDG 13, "Climate Action." For instance, developing and implementing new technologies to harness energy from waves and tides can promote renewable energy usage and reduce reliance on fossil fuels, aligning with SDG 7, "Affordable and Clean Energy."

Marine energies are still early in their development and their potential is largely untapped, but our oceans could supply the entire world with power and begin to eradicate our dependency on fossil fuels. As scientists and governments further research and develop marine energy, we can expect (and hope) that it will become a significant global energy source in the next decade. This book chapter advances SDGs 7, 11 and 13.
To establish an estimation procedure for reliable catch amount of illegal, unreported and unregulated (IUU) fishing, light-gathering fishing operations in the northwestern Pacific were analyzed based on the Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band (DNB) data provided by the Suomi National Polar Partnership (SNPP) satellite. The estimated fishing activities were compared with the navigation tracks of vessels obtained from the automatic identification system (AIS).
This study was conducted to investigate how the legal framework governing the Bangladeshi fishery sector can be reformed through measures such as governance reform, increasing coordination between administrative bodies and educating key stakeholders, including fishermen. In doing so, this paper evaluates how Bangladeshi fishery laws can facilitate sustainable development and improved environmental outcomes for coastal and marine living resources.
The United Nations Sustainable Development Goals (SDG), adopted in September 2015, are accompanied by targets which have to be met individually and collectively by the signatory states. SDG14 Life Below Water aims to lay the foundation for the integrated and sustainable management of the oceans. However, any environmental management has to be based around targets which are SMART – specific, measurable, achievable, realistic and time bounded – otherwise it is not possible to determine whether management actions are successful and achieve the desired aims.

Since the 1950s the amount of plastics in the marine environment has increased dramatically. Worldwide there is a growing concern about the risks and possible adverse effects of (micro)plastics. This paper reflects on the sources and effects of marine litter and the effects of policies and other actions taken worldwide. Current knowledge offers a solid basis for effective action. Yet, so far the effects of policies and other initiatives are still largely insufficient.
Fisheries constitute an important source of livelihoods for tens of thousands of poor people in the southwest coastal region of Bangladesh, and they supply a significant portion of protein for millions. Among the various threats fisheries in the southwest coastal region will face because of climate change, adverse impacts from increased aquatic salinity caused by sea level rise will be one of the greatest challenges.
The increasing popularity of marine wildlife tourism (MWT) worldwide calls for assessment of its conservation outcomes and the development of appropriate management frameworks to ensure the conservation of the species and habitats involved as well as the long-term sustainability of this industry. While many studies have examined the positive and/or negative implications of particular forms of MWT, few have attempted to identify factors of concern shared across different types of marine tourism, or examine their implications for sustainability in a broader perspective.
Marine plastic pollution has been a growing concern for decades. Single-use plastics (plastic bags and microbeads) are a significant source of this pollution. Although research outlining environmental, social, and economic impacts of marine plastic pollution is growing, few studies have examined policy and legislative tools to reduce plastic pollution, particularly single-use plastics (plastic bags and microbeads). This paper reviews current international market-based strategies and policies to reduce plastic bags and microbeads.
Global food security is a priority for the future development agenda of the United Nations. Given the high dependence of the modern global food production system on the continuous supply of commercial phosphorus (P) fertilizers, the goal of achieving global food security could be hampered by any form of paucity of the global P resource. P is a finite, non-substitutable, non-renewable, and geographically restricted resource. The anthropogenic influences on this critical resource are likely to pose a number of challenges to its sustainability.
To advance goal 14 (life below water), age and growth studies have been carried out on fish so that scientists and fisheries can better understand exploitation rates and assess stock levels.
