Asia is home to some of the planet’s richest coastal wildlife, yet they are vanishing. Governments sign agreements, mark zones on maps, publish roadmaps. Between declaration and actual protection lies a gap: zones protected on paper often remain without genuine management or funding.
The essentials
- Asia is protecting its biodiversity too slowly: depending on the sub-region, it would need to accelerate by between two and six times to reach targets set for 2030.
- Three-quarters of Asia’s terrestrial ecoregions fall short of the minimum protection threshold set by international agreements.
- Southeast Asian mangroves continue to decline, converted into aquaculture farms or industrial zones, sometimes even where regulations exist to protect them.
- Territories managed by local communities can now be counted toward protection targets, but access to financing for sustainable management remains difficult.
- Funding effective management—not simply drawing lines on maps—is the central challenge.
Three-quarters of Asia’s ecoregions are insufficiently protected
Scientists have known for a long time that maintaining wildlife in a given region requires a minimum protected area. This threshold varies depending on species, habitats, and degree of degradation. No universal figure exists, but broad trends are clear.
In Asia, the numbers are worrying. Across all terrestrial ecoregions studied, 73% have less than 17% of their area included in protected areas. This concerns notably the tropical forests of Borneo, the wetlands of the Mekong Delta, and the mountain ecosystems of the eastern Himalayas.
These figures come primarily from the World Database on Protected Areas and national sources for 2020. They describe the present state, not projections.
The lag is measurable
The Kunming-Montreal Global Biodiversity Framework, adopted in December 2022, commits Parties to targeting at least 30% protection of land, inland water, and marine and coastal spaces by 2030. This is the “30x30” target.
For Asia, the road is still long. Depending on the sub-region, the rate of protected area expansion would need to accelerate by a factor of 2.4 to 5.9. In East and Southeast Asia, the factor would be 2.4. In South Asia, it would rise to 5.9.
These figures hide very different situations from one country to another. Bhutan, Fiji, and some Indonesian island provinces have already reached or exceeded targets. Conversely, the Philippines and coastal Vietnam combine ecosystems of exceptional biological richness with protection rates among the lowest in the region. A uniform regional policy cannot treat the same way a country that lacks area to protect and a country that lacks money to manage what it has already classified.
Mangroves reveal the problem in all its clarity
Mangroves are the test ecosystem for Asian coastal conservation. They store four times more carbon per hectare than terrestrial tropical forests. Mangroves serve as nurseries for many species; the figure of 75% concerns Queensland, not all of Southeast Asia. They absorb wave energy and can provide coastal protection whose cost-benefit ratio may be favorable depending on the location, hazards, and compared infrastructure.
Yet they are declining. In Southeast Asia, they have been converted on a large scale for aquaculture, land reclamation, and industrial uses, sometimes despite existing regulations.
The paradox is precise. A mangrove can appear in an official national planning document, figure in an international conference speech, be cited in a roadmap, and have no actual budget to monitor it, manage it, or compensate the communities living there. Being named as a priority and being funded as a priority are two distinct political decisions, often made at different times and according to different logics.
The problem stems from disconnection between formal recognition and effective management.
OECMs, a serious avenue with real limitations
Other Effective area-based Conservation Measures, known by the acronym OECM, represent the most promising tool developed in recent years. The principle is simple: territories managed by local communities, private companies, Indigenous groups, or sectoral administrations can produce conservation results comparable to those of an official nature reserve without having that legal status.
For Southeast Asian countries where vast coastal areas are de facto managed by fishing communities for generations, this is a real opportunity. These zones can be counted toward 30x30 targets without imposing land changes that would be politically impossible and economically destructive for local populations.
In July 2026, a regional workshop held in Tokyo revised the OECM roadmap for the Asia region, bringing together more than 40 experts from governments, conservation organizations, and research institutions. The objective: to move from awareness-raising to concrete implementation, monitoring, and long-term management. The ASEAN Biodiversity Plan 2024-2030, launched in October 2024, also encourages use of OECMs.
But recognizing a zone does not pay forest rangers. A fishing community that has sustainably managed a coral reef for thirty years may see its territory officially recognized as an OECM and remain exposed to economic pressures that drive it to convert the land to more profitable short-term activities, lacking alternative income sources. Access to multilateral financing varies by context, and complex procedures favor institutional actors over local governance structures.
Money: between promises and actual transfers
The Kunming-Montreal Framework aims to mobilize at least 200 billion dollars per year for biodiversity by 2030, of which at least 30 billion dollars per year in transfers from developed to developing countries by 2030. The commitments exist. Actual disbursements follow less readily than commitments do.
The Global Environment Facility finances conservation projects in Asia, but its validation cycles, between 18 and 36 months for a standard project, are not suited to ecosystems degrading over a few seasons, measurable by satellite in near real-time.
Voluntary carbon credit markets represent a complementary avenue. Mangroves, tropical peatlands, and seagrass meadows generate measurable sequestration that interests corporate buyers. But these markets have gone through repeated credibility crises: Asian forest projects sold as carbon offsets have encountered integrity problems that increased reputational risk and investor skepticism, degrading trust and perceived value in certain credit segments, particularly undifferentiated forest credits.
The article on China’s massive reforestation efforts battered by drought illustrates a parallel difficulty: even when financing exists and plantations are made, climatic conditions can erase years of work. Asian coastal conservation faces the same vulnerability, with an additional constraint: coral reefs are among the most expensive and most difficult ecosystems to restore once degraded.
Concrete measures required
Southeast Asia’s coastal ecosystems are interconnected. Coral reef degradation reduces coastal protection, which accelerates mangrove erosion. This cycle is documented in scientific literature. Beyond certain degradation thresholds, restoration becomes more costly and less predictable.
For governments, this means two things often treated separately. First, classify zones: mapping, consultation, legal mechanisms, monitoring. Second, fund them so they are actually managed: staff, equipment, surveillance, rule enforcement. Available data show that assessment of management effectiveness in protected areas remains poorly covered in Asia. We know how many zones are classified.
We know far less whether they are actually managed.
The Asian Development Bank has developed blended financing instruments combining concessional loans and conservation results guarantees. These mechanisms remain underutilized, notably because they require administrative capacities that beneficiary governments do not always possess. A small island state may have solid international commitments and ecosystems of exceptional biological value without the teams to assemble a file conforming to international donor standards.
Three signals will indicate whether the trajectory changes before 2030. First, the proportion of Asian protected areas with an effective management plan and documented budget. Second, the actual disbursement rate of Kunming Fund commitments to Southeast Asian countries. Finally, the evolution of mangrove surface area measured by satellite; ESA Sentinel and JAXA data allow monitoring at ten-meter resolution, making conversions detectable in near real-time.
If these three signals improve together by 2027, the scenario of a turning point before 2030 remains possible. If disbursements continue to lag while declarations accumulate, the gap between formal commitment and actual protection will widen further. And catch-up costs will increase.
Actors testing concrete solutions
Several ongoing initiatives deserve precise mention because they directly address the disconnection between classification and financing.
The ASEAN Centre for Biodiversity conducts regional activities to help local administrations and community groups document their management practices according to internationally recognized criteria, to support monitoring and experience-sharing.
The Philippines launched in 2024 a payments for ecosystem services project covering watersheds. The mechanism remains limited in scale, but it directly tests the model in which funded protection follows classification, not the reverse.
Indonesia, which harbors approximately 20% of the world’s remaining mangroves, has integrated their conservation into its carbon neutrality plan. The World Bank is financing the Mangroves for Coastal Resilience project there via the Sustainable Landscape Management Multi-Donor Trust Fund.
These examples do not resolve the problem at regional scale. They show that solutions exist, that they can work, and that the link between zone recognition, financing, and effective management can be established when institutions commit to it.
The question for the next five years is simple to state, difficult to resolve: can Asian institutional architecture—ASEAN, the Asian Development Bank, bilateral mechanisms—move from roadmaps to predictable financial flows? The signals to measure this exist. The actors working on this problem are identifiable. And the window during which investing in protection remains cheaper than restoring what will have vanished is itself calculable. Which is sufficiently rare to be worth stating.
