New Report: Governments Falling Short on Promises of Effective Biodiversity Protection

Ocean protection quality is lagging behind quantity: Applying a scientific framework to assess real marine protected area progress against the 30 by 30 target

This new analysis^* of the world's largest 100 marine protected areas (MPAs) published in May 2024 in Conservation Letters suggests that governments are falling short on delivering the promise of effective biodiversity protection due to slow implementation of management strategies and failure to restrict the most impactful activities:

Only one-third of the area designated within these MPAs provides a level of protection that is likely to yield meaningful conservation benefits.
One-quarter of the area within these MPAs is not yet implemented

Over one-third of the area within these MPAs allows industrial or other highly impactful activities
Most of the large, fully and highly protected areas are in isolated overseas territories

^*MPA assessments in the publication were conducted in February 2023. The assessments currently available here may reflect more recent changes to their status.

The Marine Protection Atlas (MPAtlas) is building a comprehensive global database of marine protection to identify, track, and advocate for fully and highly protected areas.

MPAtlas uses The MPA Guide's science-based framework to identify marine protected areas Stage of Establishment and Level of Protection, which are linked to expected conservation outcomes. MPAtlas shows how much of the ocean is currently fully or highly protected, highlights where MPAs are not yet implemented on the water, and much more. By focusing on the quality, in addition to the quantity, of marine protection, MPAtlas supports international progress toward effective marine conservation.

The MPAtlas assessment database is continually growing and will be regularly updated when new assessments are available. For visualization and data analysis, our assessment data is linked to geospatial boundaries from the World Database on Protected Areas and other sources. The dataset does not contain boundaries for all global MPAs, only those that have been assessed.

The MPA Guide: a framework to achieve global goals for the ocean

The MPA Guide is a groundbreaking science-driven, policy-relevant framework to categorize marine protected areas and link their outcomes for nature and people.

We welcome feedback or contributions to our database

Assess

We use science-based frameworks to assess the Stage of Establishment and Level of Protection of MPAs across the globe, creating quality metrics that supplement the official World Database on Protected Areas reporting.

Collaborate

We partner with conservation organizations, scientists and governments to apply science-based frameworks to MPAs globally

Report

We use our data to track and visualize fully and highly protected MPAs around the world. We contribute our data to conservation research as well as produce our own global and regional reports on MPA progress.

Largest marine protected areas

89%

of global marine protected area is in the 100 largest marine protected areas.

36%

of the 100 largest marine protected areas is in implemented fully / highly protected areas.

11%

of global marine protected area is in over 18,000 smaller marine protected areas.

Blue Parks

Blue Parks aim to unite a global ocean refuge system of effective MPAs that covers 30% of the ocean to safeguard marine biodiversity. The Blue Park Criteria are science-based standards for conservation effectiveness, which provide blueprints for effective MPAs and a framework for evaluating the biodiversity benefits of MPAs. By awarding MPAs that meet the Blue Park Criteria, the Blue Parks initiative incentivizes and accelerates effective marine protection.

marine protected areas have received Blue Park Awards.

These areas cover roughly 11% of the total marine protected area in the world.

New Blue Parks in 2024

Three marine protected areas (MPAs) won prestigious Blue Park Awards for exceptional marine wildlife conservation at the 9th Our Ocean Conference in 2024. Tristan da Cunha (UK), Gitdisdzu Lugyeks Marine Protected Area (Kitasoo Xai'xais First Nation), and Siete Pecados Marine Park (Philippines) join a growing network of 30 awarded Blue Parks around the global ocean that have met the highest science-based standards for conservation effectiveness. The three new Blue Parks cover a total area of 757,403 square kilometers (292,435 sq. mi.). Their addition brings the Blue Park Network to a total of 3.5 million square kilometers (1,351,358 sq. mi) of ocean area effectively protected in the waters of 23 countries.
