Key figures

What the numbers say

In 2025, Congo, Rep.'s marine protected areas (% of territorial waters) rose 10.6 percentage points on 2024 (from 3.5% to 14.1%).

This year's change was 63.0 standard deviations above that average, so it was unusually large compared with the rest of the record.

On record, the biggest yearly rise was 10.6 percentage points in 2025 and the biggest yearly fall was 0.2 percentage points in 2020. The numbers show how large and when, not why; for the cause, look at what happened in that country in those years.

From 2016 to 2025 there is no clear straight-line trend: a straight line explains 27% of the movement over 10 observed years, so the value is moving around more than it is heading anywhere.

What this measures

Marine protected areas are areas of intertidal or subtidal terrain--and overlying water and associated flora and fauna and historical and cultural features--that have been reserved by law or other effective means to protect part or all of the enclosed environment.

Limitations: The data source for this indicator is the World Database on Protected Areas (WDPA), the most comprehensive global dataset on marine and terrestrial protected areas available. The extent to which the land areas, including inland waters, and territorial waters of a country/territory are protected is useful for planning purpose to protect biodiversity. However, it is neither an indication of how well managed the terrestrial and marine protected areas are, nor confirmation that protection measures are effectively enforced. Further, the indicator does not provide information on non-designated or internationally designated protected areas that may also be important for conserving biodiversity.

Regional and income-group figures are computed by the World Bank as a weighted average.
