The ocean plays a central role in supporting all life on Earth and mitigating climate change; yet the marine ecosystem is facing pressure at an unprecedented rate and magnitude from both global climate changes and regional or local anthropogenic activities. This is manifested by the fact that the ocean ecosystem is increasingly threatened at the global scale by warming, acidification and deoxygenation - primarily associated with climate change, and at the regional scale by eutrophication - largely driven by fertilizer use on land.
While science and increased knowledge are key to seeking feasible solutions towards sustainable interactions between society and the ocean, our current understanding of the ocean and its ecosystems is far from complete. Thus, interdisciplinary research in deciphering the complex processes governing the ocean at a system level with better integration of observations and models is needed. Such a perspective is true for both global and local studies with the latter requiring the additional consideration of context within regional and global changes.
With foreseeable global population growth, and its resulting societal and economic needs, new ways of development and governance is clearly needed in order to maintain sustainability. It is in this arena that, opportunities have emergedwith ecosystem-based management (EBM) and planning. EBM is a multi-faceted, integrated approach that strives to maintain healthy, productive, and resilient ecosystems that provide the goods and services required by resident and migrant user populations (including humans). This concept is well aligned with blue economy or sustainable development goals.
This presentation will highlight a case study of the Greater Bay Area of the Pearl River Delta, where I will identify knowledge gaps and challenges towards integrated ocean management and governance of this economically important marine ecosystem. This is an essential component of the new initiative just launched as part of a major development of high technologies plan in the Guangdong-Hong Kong-Macao Bay Area (also known as Greater Bay Area), one of the most highly populated bay areas in the world, home to over 69.5 million people, with a total GDP of over $1.69 trillion in 2017.
