Engaging the tropical majority to make ocean governance and science more equitable and effective

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.

Participatory monitoring drives biodiversity knowledge in global protected areas

Protected areas are central in strategies to conserve biodiversity. Effective area-based conservation relies on biodiversity data, but the current biodiversity knowledge base is insufficient and limited by geographic and taxonomic biases. Public participation in biodiversity monitoring such as via community-based monitoring or citizen science increases data collection but also contributes to replicating these biases or introducing new ones.

Retaining natural vegetation to safeguard biodiversity and humanity

Global efforts to deliver internationally agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services have been poorly integrated. These goals rely in part on preserving natural (e.g., native, largely unmodified) and semi-natural (e.g., low intensity or sustainable human use) forests, woodlands, and grasslands. To show how to unify these goals, we empirically derived spatially explicit, quantitative, area-based targets for the retention of natural and semi-natural (e.g., native) terrestrial vegetation worldwide.

Heavy reliance on private finance alone will not deliver conservation goals

The Kunming-Montreal Global Biodiversity Framework envisages an increasing reliance on large-scale private finance to fund biodiversity targets. We warn that this may pose contradictions in delivering conservation outcomes and propose a critical ongoing role for direct public funding of conservation and public oversight of private nature-related financial mechanisms.

A Comparative Analysis of Protected Area Management Effectiveness (PAME) Evaluation Tools for the Pacific Islands Region

This report was commissioned by the Secretariat of the Pacific Regional Environment Programme (SPREP) to raise awareness and understanding of the tools available to evaluate Protected Area Management Effectiveness (PAME); to provide case studies from the region on PAME assessment; and to help inform decision-making when choosing tools and planning assessments.

Gaps and weaknesses in the global protected area network for safeguarding at-risk species

Protected areas are essential to biodiversity conservation. Creating new parks can protect larger populations and more species, yet strengthening existing parks, particularly those vulnerable to harmful human activities, is a critical but underappreciated step for safeguarding at-risk species. Here, we model the area of habitat that terrestrial mammals, amphibians, and birds have within park networks and their vulnerability to current downgrading, downsizing, or de-gazettement events and future land-use change.

The effectiveness of global protected areas for climate change mitigation

Forests play a critical role in stabilizing Earth’s climate. Establishing protected areas (PAs) represents one approach to forest conservation, but PAs were rarely created to mitigate climate change. The global impact of PAs on the carbon cycle has not previously been quantified due to a lack of accurate global-scale carbon stock maps. Here we used ~412 million lidar samples from NASA’s GEDI mission to estimate a total PA aboveground carbon (C) stock of 61.43 Gt (+/− 0.31), 26% of all mapped terrestrial woody C.

The ‘Paper Park Index’: Evaluating Marine Protected Area effectiveness through a global study of stakeholder perceptions

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.

National-level evaluation of a community-based marine management initiative

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.
