Immense concern for the sustainability and wastage of fish maw byproducts were expressed by interviewees. They reported that fish are becoming harder to catch and that sizes of fish caught are declining.

Understanding perceived equity is key, equity subjective, context-dependent and has implications for legitimacy, cooperation and wellbeing. Since gender in combination with other social characteristics, influence how people benefit or participate in management, examining perceived fairness from an intersectional perspective is crucial.

This project - Disaster Risk Reductino and Climate Change Impact Survey if Cultural Sites in the Republic of Palau: Reconnaissance Survey is the first phase of a longer-term initiative to examine archaeologically and culturally significant sites across the archipelago and assess their vulnerability to climate change, including but not limited to modelled projections of rising sea levels and sedimentation and erosion of sites vis-a-vis tidal inundation and rainfall.

In 2018, the Parties to the Convention on Biological Diversity (CBD) adopted a decision on protected areas and other effective area-based conservation measures (OECMs). It contains the definition of an OECM and related scientific and technical advice that has broadened the scope of governance authorities and areas that can be engaged and recognised in global conservation efforts. The voluntary guidance on OECMs and protected areas, also included in the decision, promotes the use of diverse, effective and equitable governance models, the integration of protected areas and OECMs into wider landscapes and seascapes, and mainstreaming of biodiversity conservation across sectors.

Work on the poet-2020 global biodiversity framework is now well advanced and will outline a vision, goals and targets for the next decade of biodiversity conservation and beyond. For the effectiveness of Protected areas and other effective area-based conservation measures, an indicator has been proposed for areas meeting their documented ecological objectives.

There is a growing recognition that conservation strategies should be designed accounting for cross-realm connections, such as freshwater connections to land and sea, to ensure effectiveness of marine spatial protection and minimize perverse outcomes of changing land-use. Yet, examples of integration across realms are relatively scarce, with most targeting priorities in a single realm, such as marine or freshwater, while minimizing threats originating in terrestrial ecosystems. To date, no study has optimized priorities across multiple realms to produce a spatially explicit integrated conservation plan that simultaneously accounts for multiple human activities at a national scale. This represents a major gap in the application of existing cross-realm planning theory. We present a national scale conservation framework for selecting protected areas using a case study of Papua New Guinea (PNG) that integrates multiple systems and ecological connectivity to account for cross-realm benefits and minimize threats of land-use and climate change. The relative importance of both the forests and inshore reef environments to PNG subsistence and commercial livelihoods emphasizes the importance of considering the connections between the land and sea. The plan was commissioned by the PNG Conservation and Environment Protection Authority and identifies a comprehensive set of priorities that meet conservation targets in both the land and sea. Our national-scale prioritization framework is useful for agencies and managers looking to implement actions given multiple objectives, including watershed management and biodiversity protection, and ensures actions are efficient and effective across the land and sea.

We report three major and confronting environmental issues that have received little attention and require urgent action. First, we review the evidence that future environmental conditions will be far more dangerous than currently believed. The scale of the threats to the biosphere and all its lifeform including humanity is in fact so great that it is difficult to grasp for even well-informed experts. Second we ask what political or economic system, or leadership, is prepared ti handle the predicted disasters, or even capable of such actions. Third, this dire situation places as extraordinary responsibility on scientists to speak out candidly and accurately when engaging with government, business and the public.

This policy analysis identifies threats to coral reefs, evaluates the effectiveness of the existing legal framework to address these threats and formulates recommendations to strengthen community-based natural resource management in Solomon Islands coral reefs of crucial importance for food security and rural livelihoods in the archipelago. Logging is a major yet often overlooked threat to coral reefs in the country. Large-scale logging operations cause massive erosion, which has a detrimental effect on water quality. The shipping accidents oil pollution and uncontrolled construction of log pond associated with the logging industry also have a significant impact on coastal ecosystems.

Increasingly frequent severe coral bleaching is among the greatest threats to coral reefs posed by climate change. Global climate models (GCMs) project great spatial variation in the timing of annual severe bleaching (ASB) conditions, a point at which reefs are certain to change and recovery will be limited.

Breeding success of 5 Cory’s shearwater Calonectris diomedea sub-colonies of Lavezzu Island (Lavezzi Archipelago, Corsica) was checked annually for 25 consecutive years from 1979 to 2004. Between 1989 and 1994, 4 ship rat Rattus rattus controls were performed in several subcolonies. In November 2000, rats were eradicated from Lavezzu Island and its 16 peripheral islets (85 ha) using traps then toxic baits. We compare cost (number of person-hours required in the field) and benefit (Cory’s shearwater breeding success) of control and eradication. The average breeding success doubled when rats were controlled or eradicated (0.82) compared to the situation without rat management (0.45). Moreover, the average breeding success after eradication (0.86) was significantly (11%) higher than after rat controls (0.75). Furthermore, the great variation in breeding success recorded among sub-colonies both with and without rat control declined dramatically after eradication, suggesting that rats had a major impact on breeding success. The estimated effort needed to perform eradication and checking of the permanent bait-station system during the year following eradication was 1360 person-hours. In contrast, rat control was estimated to require 240 or 1440 person-hours per year when implemented by trained and untrained staff, respectively. Within 6 yr, eradication cost is lower than control cost performed by untrained staff and confers several ecological advantages on more ecosystem components than Cory’s shearwater alone. Improved eradication tools such as hand or aerial broadcasting of toxic baits instead of the fairly labour-intensive eradication strategy we used would dramatically increase the economic advantage of eradication vs. control. Therefore, when feasible, we recommend eradication rather than control of non-native rat populations. Nevertheless, control remains a useful management tool when eradication is not practicable.
