The Earth System Governance project is a global research alliance that explores novel, effective governance mechanisms to cope with the current transitions in biogeochemical systems of planet. A decade after its inception, this article offers an overview project's new framework (which built upon review existing earth system research), goal which continue stimulate pluralistic, vibrant and relevant community. This composed contextual conditions (transformations, inequality, Anthropocene...

Abstract The SARS-CoV-2 pandemic is not only a threat to physical health but also having severe impacts on mental health. Although increases in stress-related symptomatology and other adverse psycho-social outcomes, as well their most important risk factors have been described, hardly anything known about potential protective factors. Resilience refers the maintenance of despite adversity. To gain mechanistic insights relationship between described resilience specifically current crisis, we...

The Blue Economy is an ocean based economic growth model gaining traction around the world. way in which conceived and understood differs significantly across different sets of actors. A particular area contestation exists industries or sectors can be considered to 'Blue'.

Expectations about ecosystem based management (EBM) differ due to diverging perspectives what EBM should be and how it work. While by its nature requires trade-offs made between ecological, economic social sustainability criteria, the diversity of cross-sectoral perspectives, values, stakes, specificity each individual situation determine outcome these trade-offs. The authors strive raise awareness importance interaction three stakeholder groups (decision makers, scientists, other actors)...

The use of a single controlled bead milling step the microalga Tetraselmis suecica resulted in soluble fraction, rich functional proteins. This was achieved by fine-tuning processing time, thereby exploiting difference rates protein and carbohydrate release during milling. Soluble proteins were extracted under mild conditions -room temperature, no addition chemicals, pH 6.5-, with yield 22.5% specific energy consumption 0.6 kWh kgDW-1, which is within recommended minimum for an extraction...

Several studies have suggested Indonesia to be among the top plastic polluting countries globally. Data on presence and amounts of pollution are required help design effective reduction mitigation strategies. Research quantifying in has picked up recent years. However, a lack central coordination this research led output with different goals, methods, data formats. In study we present meta-analysis published uncover gaps biases current research, use these insights suggest ways improve future...

With multiple blue crises unfolding, momentum exists to develop and implement transformative marine governance approaches towards sustainable use of our oceans. Such will only be when they foster reflexive that questions changes existing values structures power governance. Yet, we lack understanding how change relates reflexivity. This article takes an actor perspective conceptualises reflexivity through three elements: (1) the trigger leads (2) processes single, double triple loop learning...

Despite decades of regulatory efforts to limit marine pollution, levels pollution are still high. Of particular concern in recent years is (micro)plastic pollution. Sources microplastics either intentionally added products, such as cosmetic and personal care or released unintentionally, wear from textile, tyres the breakdown larger plastic items. Marine microplastic by nature transboundary which therefore requires collaborative concerted both within between countries. Microplastic has a...

Marine ecosystems are facing substantial stress due to global environmental challenges that have escalated in magnitude and impact. The European Green Deal (EGD) is acting as a driver change innovation of marine governance through the development ambitious sustainability objectives around among others energy, plastics, transport biodiversity. For example, offshore wind energy an expanding sector, decarbonization maritime has become priority, more plastic pollution sources being regulated,...
