Contagious exploitation of marine resources

Global seafood sourcing networks are expanding to meet demand. To describe contemporary fishery expansion patterns, we analyzed the worldwide exploitation of sea cucumber (Echinodermata: Holothuroidea) traded via Hong Kong for consumers in China. In just 15 years (1996-2011), the sea cucumber sourcing network expanded from 35 to 83 countries; sea cucumber fisheries serving the Chinese market now operate within countries cumulatively spanning over 90% of the world\u27s tropical coastlines. The emergence of such fisheries in nations where they were previously absent could not be explained either by their national governance capacity or by their distance from Hong Kong. Surging imports from these new fisheries have compensated for declines in long-standing fisheries elsewhere. The case of commercial sea cucumber trade for the Chinese market exemplifies a new global extraction phenomenon that we call contagious resource exploitation - A fast-moving system resembling a disease epidemic, where long-distance transport expedites largescale expansion followed by diffusive local spread into neighboring areas. Multi-level and multi-scale decision making is urgently needed to control and mitigate the effects of contagious exploitation

Science-Industry Collaboration:Sideways or Highways to Ocean Sustainability?

There is substantial and unexplored potential for scientists to engage with the private sector for a sustainable ocean. The importance of such cooperation is a frequent emphasis of international dialogues and statements, it is embedded within the Sustainable Development Goals, and has been championed by prominent business leaders and scientists. But an uncritical embrace of science-industry collaboration is unhelpful, and candid reflections on the benefits and pitfalls that marine scientists can expect from actively engaging withthe private sector are rare. In this Perspective, we draw on our collective experiences working with ocean industries in different parts of the world to reflect on how this has influenced our work, the effects these collaborations have generated, and the barriers to overcome for such partnerships to become more common. In doing so, we hope to help empower a new generation of marine scientists to explore collaboration with industry as a way to develop and scale up solutions for ocean sustainability

Reconnecting to the biosphere

Humanity has emerged as a major force in the operation of the biosphere, with a significant imprint on the Earth System, challenging social-ecological resilience. This new situation calls for a fundamental shift in perspectives, world views, and institutions. Human development and progress must be reconnected to the capacity of the biosphere and essential ecosystem services to be sustained. Governance challenges include a highly interconnected and faster world, cascading social-ecological interactions and planetary boundaries that create vulnerabilities but also opportunities for social-ecological change and transformation. Tipping points and thresholds highlight the importance of understanding and managing resilience. New modes of flexible governance are emerging. A central challenge is to reconnect these efforts to the changing preconditions for societal development as active stewards of the Earth System. We suggest that the Millennium Development Goals need to be reframed in such a planetary stewardship context combined with a call for a new social contract on global sustainability. The ongoing mind shift in human relations with Earth and its boundaries provides exciting opportunities for societal development in collaboration with the biospherea global sustainability agenda for humanity
