As the global community grapples with accelerating climate change and ecosystem collapse, a critical target set under the Kunming Montreal Global Biodiversity Framework, to designate 30 percent of the world’s oceans as Marine Protected Areas (MPAs) by 2030, is now appearing increasingly unattainable. Conservationists are sounding the alarm, pointing to sluggish progress, waning political commitment, and flawed implementation strategies that are undermining this ambitious conservation milestone.
Currently, only 8.4 percent of the oceans are covered by MPAs. More alarmingly, just 2.7 percent of ocean waters are fully or highly protected, an essential benchmark for yielding tangible ecological benefits. “With less than 10 percent of the ocean designated as MPAs, and only a fraction of that being effectively protected, it is going to be difficult to reach the 30 percent target,” warns Lance Morgan, head of the Marine Conservation Institute in Seattle, Washington.
The Marine Conservation Institute has been closely tracking the status of MPAs globally through its online atlas, mapping efforts by 196 countries that committed to the 30 percent target in 2022. While the goal is ambitious and symbolically significant, the reality is starkly different. Many countries have yet to enact comprehensive measures to meet their pledges, and recent geopolitical moves have raised serious concerns about sustained commitment.
One glaring example is the rollback of protections by the United States. In April, an executive order issued under President Donald Trump authorized industrial-scale fishing across large swathes of an existing MPA in the Pacific Ocean. Morgan highlighted this reversal as emblematic of a broader trend where once bipartisan support for marine protection is crumbling. “We see countries like the US reversing course and abandoning decades of bipartisan efforts,” he lamented.
While the number of MPAs globally (16,516 as of now) might sound encouraging, the quality and effectiveness of these designations vary drastically. Many MPAs are “paper parks,” where protections exist on paper but lack enforcement and proper management. Joachim Claudet, a socio-ecology marine researcher at France’s CNRS, notes that only one-third of MPAs have robust protection measures in place. “Only a third of them have levels of protection that would yield proper benefits for fish,” he explained, underscoring that effective MPAs must go beyond symbolic boundaries.
The lack of uniform standards and enforcement mechanisms is a central issue. While some MPAs ban all forms of fishing and human interference, others impose few or no restrictions on industrial activities. Daniel Pauly, a leading fisheries scientist at Canada’s University of British Columbia, argues that marine protected areas have been misappropriated not as sanctuaries for biodiversity, but as tools for enhancing fish catches. “They have not really been proposed for the protection of biodiversity,” he said, adding that the underlying motive often revolves around commercial exploitation.
Pauly advocates for a redefinition of what constitutes a “proper” MPA. According to him, a well-functioning MPA should serve as a breeding ground that exports fish to non-protected zones. This ecological spillover effect, backed by marine biology research, ensures long-term sustainability for both conservation and fisheries. Yet without rigorous enforcement and meaningful restrictions, MPAs fail to serve their intended purpose.
The problem is not just about surface area. It is about strategy. Global leaders must now reckon with the hard truth. Mere declarations will not save the oceans. Without scientific planning, cross-border cooperation, and financial investment in marine monitoring and enforcement, the 30 percent by 2030 goal risks becoming another missed opportunity in the long list of unfulfilled environmental promises.
In an era where ocean health underpins everything from global food security to climate resilience, the need for credible marine protections is not a luxury. It is a necessity. As the clock ticks toward 2030, conservationists warn that unless nations recommit with urgency and integrity, the promise of protected oceans may dissolve into nothing more than political lip service.
