African governments used this week’s Our Ocean Conference in Mombasa to push a more demanding idea of marine protection: not just areas drawn on maps, but areas that can be managed, funded and enforced — the difference between a policy announcement and an investable outcome.
In a June 18 statement, the Wildlife Conservation Society said nine African governments announced new commitments spanning newly gazetted marine protected areas (MPAs), national strategies and new planning frameworks aimed at the global 30% by 2030 target.
The emphasis on implementation is timely. As headline coverage of “30×30” grows, officials and conservation groups are increasingly warning that large designations without monitoring or compliance capacity can become ‘paper parks’ — politically useful, ecologically thin.
Dr. Jean Mensa, marine program director at WCS Tanzania, said the commitments presented at Our Ocean were “the result of years of work by governments and communities to translate ambition into action,” adding that together they show what “sustained, collaborative effort can achieve.” (WCS)
For coastal communities, the distinction is practical: enforcement determines whether fish stocks rebound, whether tourism revenues are durable, and whether habitats that buffer storms and store carbon are protected for the long term.
WCS highlighted actions at several points along the policy-to-practice pipeline. Tanzania said two marine conservation areas off Pemba, Zanzibar have now been officially gazetted, together spanning 1,300 km² of mixed-use zones. (WCS)
Tanzania also committed to begin the process of designating a proposed Kilwa MPA of 1,000–2,500 km² that WCS said would include climate-resilient coral reefs and designated important habitats for sharks, rays and marine mammals. (WCS)
The Kilwa coastline sits beside one of East Africa’s most significant cultural landscapes: UNESCO lists the Ruins of Kilwa Kisiwani and Ruins of Songo Mnara as a World Heritage property, a reminder that ocean stewardship in the region intersects with heritage protection, livelihoods and tourism.

Elsewhere, Mozambique presented plans for a national marine conservation strategy, while Madagascar committed to convert five MPAs from temporary to permanent status, with gazettement anticipated by 2028, according to WCS. (WCS)
Kenya, the host nation, committed to finalize draft marine conservation, restoration and governance regulations that WCS said would include provisions to recognize community-led ‘other effective area-based conservation measures’ (OECMs). (WCS)
A standard for “effective” protection
A parallel effort at the conference tried to make ‘effectiveness’ legible to the public. The Marine Conservation Institute said it awarded six new “Blue Park” designations at Our Ocean, tying recognition to a science-based standard that evaluates MPAs on design, governance, management, compliance and capacity.
“It’s not a numbers exercise — it’s an ocean health exercise,” said Dr. Lance Morgan, president of the Marine Conservation Institute, arguing that the 30×30 goal only matters if protected areas ‘work’ in practice. (Marine Conservation Institute)
The Blue Park list also underscored that enforcement is not one-size-fits-all. One 2026 awardee was KAWAWANA, described by the institute as an Indigenous community heritage area in Senegal — an example of conservation rooted in local governance rather than distant patrols.

Salatou Sambou, founding president and technical advisor of KAWAWANA’s managing body, the Mangagoulack Rural Community Fishermen's Association, said: “Successful conservation is one that is born of the will and commitment of communities.” (Marine Conservation Institute)
What to watch next
For donors, governments and blue-finance investors, the next signal is operational: budgets for management plans, monitoring systems, community co-management and the sometimes-unpopular restrictions that turn boundaries into biodiversity gains.
WCS described the week’s announcements as reflecting “different stage[s] of the conservation process,” a framing that matters for accountability: some areas are already legally established, others are entering planning, and others still depend on financing and governance reforms. (WCS)
