In 2025, China launched a massive restoration program for the Yangtze River and Indonesia expanded formal protection of marine areas through new marine protected areas. These figures are real and documented, but insufficient. Protected areas cover a portion of land and inland waters, but remain inadequate relative to the international target of 30% by 2030. Restoration and protection efforts coexist with persistent deforestation, though the regional pace has nonetheless slowed.
The Essentials
- Ecological restoration in Asia produces real results but remains lower than documented degradation.
- In 2025, The Nature Conservancy documents results concerning Yangtze biodiversity recovery and the expansion of Indonesian marine conservation.
- The asymmetry is structural: restoration requires structural changes and time, while certain conversion and exploitation pressures persist.
- Protected areas remain inadequate relative to the 30% target by 2030.
- Three trajectories are possible: status quo, conditional financing, or reform of production systems.
The Yangtze and Riau: What Restoration Can Do
The Yangtze River is one of the most degraded freshwater ecosystems on the planet. For decades, intensive fishing, dams, and industrial pollution decimated its fish populations and weakened its banks. On January 1, 2021, China implemented a ten-year commercial fishing ban in key Yangtze basin waters and launched a riverbank restoration program. Measurable improvements in aquatic resources were observed following the fishing ban. Documented results include improvements in fish populations in certain zones.
In Indonesia, Riau Province had lost a large portion of its coastal forests and mangroves to oil palm plantations and intensive aquaculture. The Bintan II/Tambelan conservation zone, covering approximately 844,000 hectares, was established on December 17, 2024; its public announcement came in February 2025. Restored mangroves store carbon, protect coastlines from storms, and recreate nurseries for fish.
These two programs are among the advances that The Nature Conservancy and UNEP document as milestones. They demonstrate that large-scale restoration is technically and politically possible when states decide to commit resources. This point deserves to be stated clearly before proceeding further.
Destruction During the Same Period
The problem lies in simple arithmetic. While China was restoring the Yangtze and Indonesia was expanding its marine protected areas, agricultural expansion, logging, and urban development persisted elsewhere on the continent.
UNEP reported that Southeast Asia lost 13% of its forests since 1992. Restoration and degradation advance simultaneously across the continent. Comparison between restoration and degradation remains difficult to establish using homogeneous indicators.
Implemented programs operate within a legal framework that simultaneously authorizes degradation. In Indonesia, oil palm concessions fall under a system of shared authority between central and subnational authorities. In peninsular Malaysia, the area of production forest exceeds that classified as protection forest. Restoration occurs downstream of a production system in which certain sources of degradation fall within existing legal frameworks.
It is this asymmetry that raises the question of the long-term trajectory for Asian biodiversity. The bulk of degradation depends on decisions that do not fall under ecological restoration, but rather under agricultural policy, forestry policy, and global supply chains.
The 30% by 2030: The Target and the Gap Between Them
The international agreement known as 30x30, adopted at the COP15 biodiversity conference in Montreal in 2022, sets a target of 30% of terrestrial and marine surfaces conserved by 2030. Progress varies significantly according to habitat types and regions. Five years remain. Official coverage alone does not provide information on management effectiveness, which remains insufficiently documented.
Having a protected area on paper is not enough. A forest classified as a reserve but accessible to exploiters through exemption permits, a nominally protected coastal zone but unsupervised: formal protection can coexist with actual degradation. UNEP data distinguish declared protected areas from areas actually managed with adequate human and financial resources. This gap exists and merits particular attention in Asia.
The 30x30 target is a political commitment, not a budgeted program. What is most lacking is complete and comparable implementation of accounts and indicators covering the extent, condition, and other dimensions of biodiversity, to assess net change beyond sectoral announcements.
To understand what truly accounted-for restoration can accomplish in net terms, experiences around peatlands provide a useful reference point: these ecosystems, which store twice as much carbon as all the world’s forests, have demonstrated that one can precisely measure gains and losses of the same habitat type.
Who Advances Programs, and How
Facing this asymmetry, several actors work toward solutions that go beyond planting trees.
The Nature Conservancy has deployed innovative financing mechanisms in Asia-Pacific: “debt-for-nature swaps,” in which part of a country’s external debt is forgiven in exchange for measured conservation commitments. These mechanisms have enabled several Southeast Asian island states to finance marine protection programs without sacrificing economic development. The model also interests indigenous peoples of Oceania, who have developed their own approach as blue carbon stewards, demonstrating that conservation can rely on local communities as legitimate managers.
In China, Yangtze restoration rests on a combination of firm regulatory prohibition, compensation of fishers converted into river stewards, and investment in monitoring via sensors and satellite imagery. This model of converting users into conservation actors is one of the most significant advances in recent Asian programs.
In Indonesia, NGOs like Yayasan Konservasi Alam Nusantara work with coastal communities to integrate restored zones into sustainable fishing systems, making conservation economically advantageous for those who lived from degraded resources. These programs show that restoration can work when it combines economic incentive, local involvement, and regulatory constraint.
Changing the Equation: Three Trajectories for 2030-2050
Current data directly pose the question of asymmetry between progressing restoration and persisting deforestation despite the regional slowdown in its pace. Several trajectories emerge, with very different implications.
The first is status quo. Restoration financing increases, programs multiply, governments announce milestones. But legally authorized degradation persists. Projections for this scenario remain pessimistic for habitat recovery by 2100. Without verified net accounting of gains and losses, global biodiversity risks continuing to decline despite sectoral announcements.
The second trajectory introduces conditionality. Conditional financing experiments are emerging, where conservation funding could be tied to verifiable commitments to reduce new degradation zones. A country receiving restoration financing commits to not granting new concessions within a defined perimeter. This is the first test of political coherence: conservation ceases to be a program parallel to production policy and begins to condition its rules. Several financial institutions, including the Asian Development Bank, are exploring such mechanisms without yet having generalized them.
The third trajectory touches production systems themselves. Regenerative agriculture reduces pressure on primary forests by increasing yields on already degraded land. Net zero deforestation certification, imposed on supply chains, shifts commercial pressure toward producers respecting commitments. The European regulation on imported deforestation, which entered into force in 2023, creates a precedent: for covered products, companies must comply with due diligence and traceability obligations as of the regulation’s application dates. Should this mechanism scale up and extend to other markets, it changes economic calculations at the source, where degradation begins.
A mechanism discussed in several scientific forums goes further: every new degraded area would obligatorily finance restoration of an area ten times larger. This type of mandatory compensation would reverse the economics of degradation, making its true cost borne by those who profit from it. The concept is sound. Its political application remains to be built.
Signals to watch to determine which trajectory prevails: the restoration/net degradation ratio by region between 2027 and 2030, the share of actually managed protected areas relative to the 30x30 target, and the evolution of forest cover in Southeast Asia following the implementation of first supply chain certifications. These three indicators will allow trajectories to be distinguished well before 2050.
The Speed of Possible Change in 2025
Ecological recovery and socioeconomic support for communities can be conducted jointly, without an isolated causal link demonstrated here. The Yangtze is the clearest demonstration. In four years, a river declared in ecological crisis began recovering fish populations. The delay between decision and measurable results is shorter than anticipated.
This result has a direct implication for the debate on priorities: it makes the opposition between “accelerate restoration” and “block degradation sources” less relevant. Both can advance in parallel, provided that production policy ceases to be treated as an independent variable from conservation policy.
The real breakthrough will not be in an additional restoration program. It will come when a major Asian government explicitly links the granting of new agricultural or forestry concessions to a positive net biodiversity balance on its territory. This signal has not yet appeared. When it does, it will change the nature of the problem.
