... In the most optimistic scenario where all nations take immediate and drastic measures to slash down global greenhouse gas emissions (referred to as RCP2.6), the potential sea-level rise could be brought down to around 0.39 m (likely range: 0.29-0.59 m) (Oppenheimer, Glavovic, Hinkel, et al. 2019). Some observational scientists believe that these future SLR estimates may be too optimistic considering just the current rates of ice loss from the Greenland and Antarctic ice sheets, and these ice loss rates are only accelerating (Bajaj 2019). ...

The book has been a culmination of joint efforts and initiatives by Konrad Adeanuer Stiftung India office, The Energy and Resources Institute (TERI), National Maritime Foundation (NMF) and Federation of Indian Chambers of Commerce and Industry (FICCI) to nurture and encourage a holistic discourse on Blue economy in India. FICCI, NMF and TERI with the partnership of KAS India collaborated to bring together eminent voices and thinkers on blue economy with six webinars and a hybrid national conference focusing on establishing synergies, a multidisciplinary approach and augmenting discussions for a cohesive perspective on blue economy. The focus of the book has been to build a collective dialogue on the three pillars of blue economy – maritime security, economic growth and sustainable development. The book has several chapters written by different experts from varied facets of blue economy. As the Editor and Coordinator of the Book, I am immensely thankful to all authors for their contributions.
... Global climate change and marine-related human activities threaten the ecological environment and sustainable development of the oceans. Current ocean exploration systems are not perfect in terms of energy efficiency, environmental friendliness, and sustainability [2]. Ocean exploitation and utilization are facing brutal challenges from climate change and associated environmental issues including: 1) aggravating marine pollution and its associated secondary disasters; 2) misfunctioning of marine ecosystems; and 3) growing intensity and frequency of extreme sea conditions. ...
The oceans are crucial to human civilization. They provide core support for exploitation and utilization of marine space, resources, and energy. Thus, marine infrastructures are vital to a nation’s economic sustainable development. To this end, this article first describes the main challenges in current ocean utilization, and then reviews the China’s ocean engineering progress. As such, six major sectors are evaluated: 1) global climate change and marine environment, 2) comprehensive utilization of marine space, 3) marine transportation infrastructure interconnection, 4) ocean clean energy development and maricultural facilities, 5) ecological crisis and marine engineering countermeasures, and 6) marine infrastructure operation safety and maintenance. Finally, perspectives on future directions of ocean utilization and marine infrastructure construction in China are provided.
... Mean sea level rise (SLR) could increase up to 2 m by 2100 (Oppenheimer et al. 2019), which would see damage caused by coastal flooding in Europe increase from €1.25bn per annum currently to €961bn in just over 80 years (European Commission, 2018). Urban areas situated along the North Sea coastline are particularly vulnerable to extreme SLR (a combination of SLR, tide, and storm surges). ...
... III. Measures to enhance societal adaption. These include (12) community-based adaptation, (13) Improving policies on risk reduction, (14) Infrastructure-based adaptation, (15) People relocation, (16) Relocation and diversification of economic activities, and (17) Operation of an early warning and emergency response system (Oppenheimer et al., 2019;Nicholls, 2018). ...

The Vietnamese fisheries sector, including both marine fisheries and aquaculture, has made spectacular progress in recent years, becoming one of the top seafood producing and exporting countries in the world. Looking forward, development goals of this sector must address challenges associated with climate change, including changing distribution of commercially important marine species such as tuna and disruptions to land-based aquaculture production systems. This study investigates the prospective climate change impacts on Vietnam's fisheries sector, focusing on four key commodities including capture fisheries (tuna), freshwater aquaculture (pangasius catfish and tilapia), and brackish water aquaculture (shrimp). The extent of impact varies, but climate change represents a potentially significant threat to sustainable production in each production system. Producers, policy makers, and other stakeholders need to plan for and adapt to climate change to ensure the sustainable development of Vietnam's fisheries sector.
Scientists are of the opinion that human activities are the major reason for the variation in the climate, and unfortunately, these changes are largely irreversible. Scientists have made considerable efforts to investigate the causes that have triggered climate change and how it will affect the lives of the people today and tomorrow. For the individuals at the helm of affairs, this understanding is very important to take the right direction at the right time to mitigate the effects of climate change in time to avoid irreversible long-term implications. However, the issue is complex, and certain areas remain to be addressed. Every day, the perception is getting real that climate change is a reality; thus, decision makers need to be at guards. Pakistan is no exception to the increasing impacts of climate change, which is becoming visible every passing day. The increased frequency and intensity of floods and recent extreme heat wave events should serve as an eye opener to authorities. However, despite establishing disaster management authorities at the national and provincial levels, Pakistan has been unable to properly ameliorate the impacts of disasters. This study is an effort to critically analyze the growing threats of climate change impacts, particularly focusing on growing food security issues across the country. It is estimated that Pakistan could lose approximately US$20 billion by mid-this century owing to climate change-induced rice and wheat crop production if major steps are not taken to address this alarming issue. The study concludes by suggesting climate change mitigation and adaptation and measures to address food security and to apprise the concerned authorities to take immediate steps to prepare, adapt to and mitigate climate change before it is too late.
The discourses of sustainability are inextricably linked to the influence of technology in shaping the future. Information and Communication Technology (ICT) in particular plays a crucial role in our understanding of the environment and human impacts as well as our search for future solutions to mitigate climate change. However advances in technology need to be accompanied by social innovation in order to meaningfully address the Sustainable Development Goals (SDGs). Sustainability transitions research extends the well-established field of socio-technical systems analysis by paying closer attention to environmental, economical, social, political and technical factors that can stimulate change. Yet in order to offer guidance towards future socio-technical solutions, a deeper understanding of the relations between humanity and technology is necessary. To fulfill this requirement we explore the the concept of technological mediation and identify four ICT mediated practices in sustainability transitions: information gathering, communicating, decision-making, and self-reflection. These practices are described in the context of Sustainable Development Goal 14 Life Below Water, then elaborated through a specific example: the development and use of remote sensing ocean data buoys. In discussion we demonstrate the utility of technological mediation perspective to shed light on the interdependence of society, technology and the environment, and open critical discourses on sustainability transitions that can help shape equitable future alternatives.

The West African coastal population and ecosystems are increasingly exposed to a multitude of hazards. These are likely to be exacerbated by global climate change and direct impacts from local human activities. Our ability to understand coastal changes has been limited by an incomplete understanding of the processes and the difficulty of obtaining detailed data. Recent advances in satellite techniques have made it possible to obtain rich coastal data sets that provide a solid foundation for improving climate change adaptation strategies for humanity and increasing the resilience of ecosystems for sustainable development. In this article, we review West African coastal layout and current socio-environmental challenges together with key parameters that can be monitored and several coastal management programs that rely on satellite techniques to monitor indicators at the regional level. The social, technical and scientific problems and difficulties that hinder the interest of coastal practitioners and decision-makers to use the satellite data are identified. We provide a roadmap to precisely respond to these difficulties and on how an improved satellite earth observation strategy can better support future coastal zone management in West Africa.
