Thematic Area

We are in a period of unprecedented growth in conservation philanthropy. How will this influx of private funding affect conservation agendas? Inspired by a collaborative research co-design process, this paper addresses questions about how foundations influence conservation agendas in the places they work. We draw from a case study of the world’s largest philanthropic funder of marine conservation, the David and Lucile Packard Foundation and their 20 years of investment in marine conservation in Palau and Fiji.

In ocean areas beyond national jurisdiction, various legal regimes and governance structures result in diffused responsibility and create challenges for management. Here we show those challenges are set to expand with climate change driving increasing overlap between eastern Pacific tuna fisheries and the emerging industry of deep-sea mining. Climate models suggest that tuna distributions will shift in the coming decades.

How can ocean governance and science be made more equitable and effective? The majority of the world’s ocean-dependent people live in low to middle-income countries in the tropics (i.e., the ‘tropical majority’). Yet the ocean governance agenda is set largely on the basis of scientific knowledge, funding, and institutions from high-income nations in temperate zones.

This document presents a synopsis of the current state of knowledge for hawksbill turtles in the western Pacific Ocean region, including biological and ecological knowledge of nesting and foraging populations, legislative provisions, and detailed recommendations and proposals for addressing identified deficiencies.

At least 150 marine species have shown impacts from ocean noise pollution, but it has been difficult to specify the exact scenarios where ecosystem and population consequences from underwater noise will occur. Therefore, managing this threat requires a precautionary approach.

Governments around the world are increasingly committed to reaching terrestrial and marine conservation goals. But achieving such commitments is challenging, and conservation targets that are reached on paper, e.g., in terms of square kilometers protected, can be misleading. Designating Marine Protected Areas (MPAs) does not guarantee achieving marine conservation goals, and so-called ‘paper parks,’ i.e., MPAs that are legally designated but ineffective, are common.

Community-based approaches to conservation and natural resource management are considered essential to meeting global conservation targets. Despite widespread adoption, there is little understanding about successful and unsuccessful community-based practices because of the challenges of designing robust evaluations to estimate impacts and analyse the underlying mechanisms to impact. Here we present findings from a national scale evaluation of the ‘locally managed marine areas’ network in Fiji, a marine community-based management initiative.

We show that the high seas are colonized by a diverse array of coastal species, which survive and reproduce in the open ocean, contributing strongly to its foating community composition. Analysis of rafting plastic debris in the eastern North Pacifc Subtropical Gyre revealed 37 coastal invertebrate taxa, largely of Western Pacifc origin, exceeding pelagic taxa richness by threefold. Coastal taxa, including diverse taxonomic groups and life history traits, occurred on 70.5% of debris items.

Every year, the amount of plastic waste entering aquatic ecosystems is estimated between 9-14 million tons and this projection could nearly triple to 23-37 million tons per year by 2040. A report by the Ellen MacArthur Foundation has revealed that there are now over 150 million tonnes of plastics in the oceans. That's about one tonne of plastics for every three tonnes of fish. If the trend continues, plastics will outweigh fish in the oceans by 2050. This results in risks to human health and well-being through ingestion of seafood and fish contaminated with plastics.

The intersection of potential global targets and commitments for ocean conservation with the COVID-19 pandemic in 2020 has resulted in an opportunity to rethink the future of marine area-based conservation tools, particularly for marine protected and conserved areas (MPCAs). As MPCAs continue to provide essential ecological, social and economic services, current approaches to establishing and managing these areas require an understanding of the factors that drive the pressures they face.
