Trang chủIn the context of intensifying climate change and increasing pressure from socio-economic development on natural resources, identifying sustainable financial mechanisms for nature conservation has become an urgent priority. One of the financial instruments that has gained increasing attention and has been effectively implemented in many countries in recent years is the Payment for Ecosystem Services (PES) mechanism. In Viet Nam, following the initial success of the forest environmental services payment policy, the development of a payment mechanism for marine and wetland ecosystem services is considered an important direction to mobilize social resources for biodiversity conservation.
The potential of ecosystem services from marine and wetland environments
Marine and wetland ecosystems play a crucial role in Viet Nam’s sustainable development. With a coastline of more than 3,260 kilometers and a rich network of lagoons, mangroves, tidal flats, estuaries, and coastal wetlands, these ecosystems provide a wide range of essential services to human society.
First and foremost, marine and wetland ecosystems are vital for maintaining fisheries resources and supporting the livelihoods of millions of coastal residents. Many species of fish, shrimp, crabs, and mollusks rely on mangroves, seagrass beds, or coral reefs as natural breeding and nursery grounds. In addition, these ecosystems serve as natural barriers that protect coastal areas from storms, strong waves, and erosion, thereby reducing damage caused by natural disasters.
Furthermore, wetland ecosystems—particularly mangrove forests and coastal marshes—have a remarkable capacity to absorb and store large amounts of carbon, playing an important role in mitigating greenhouse gas emissions. Their scenic values also contribute significantly to ecotourism development, environmental education, and scientific research, generating considerable socio-economic benefits for local communities.
However, over the past decades, marine and wetland ecosystems in Viet Nam have faced increasing pressure from urban expansion, aquaculture development, overexploitation of resources, and environmental pollution. Large areas of mangrove forests have declined, coral reefs have deteriorated, and many lagoons and estuarine wetlands have been reduced due to coastal reclamation and infrastructure development. This situation highlights the urgent need for effective financial mechanisms to support ecosystem conservation and restoration.
Payment for ecosystem services – a financial instrument for conservation
Payment for Ecosystem Services is a mechanism through which organizations and individuals who benefit from ecosystem services contribute financially to activities that protect, maintain, and enhance those ecosystems. The mechanism follows the principle that “beneficiaries pay,” while also creating economic incentives for local communities to actively participate in conservation efforts.
In Viet Nam, the forest environmental services payment policy has been implemented since 2011 and has achieved significant positive results. Each year, the policy generates thousands of billions of Vietnamese dong, contributing to improved livelihoods for forest-dependent communities and enhancing the effectiveness of forest management and protection. This success provides an opportunity to expand the PES mechanism to other ecosystems, including marine and wetlands.
For marine and wetland ecosystems, several types of services could potentially be included in a payment mechanism, such as coastal protection, maintenance of fisheries resources, blue carbon sequestration and storage, scenic and recreational values for ecotourism, and the maintenance of water quality and biodiversity. Potential payers may include tourism enterprises, aquaculture operators, marine resource extraction companies, coastal development projects, and other organizations that benefit from environmental services.
Opportunities and challenges in implementation
The development of a payment mechanism for marine and wetland ecosystem services in Viet Nam is supported by several favorable conditions. First, the legal framework for biodiversity conservation and natural resource management has been gradually strengthened. Policies related to marine conservation, wetland protection, and climate change adaptation have begun to provide a foundation for establishing new financial mechanisms.
In addition, international trends increasingly emphasize nature-based solutions and carbon markets, particularly initiatives related to “blue carbon” derived from mangroves, seagrass beds, and coastal wetlands. This presents an opportunity for Viet Nam to attract international financial resources for ecosystem conservation and restoration programs.
Nevertheless, the implementation of such mechanisms also faces significant challenges. One of the major difficulties lies in accurately identifying and valuing ecosystem services. Compared with terrestrial forests, marine and wetland ecosystems are more complex and difficult to measure and monitor. Furthermore, identifying both service providers and beneficiaries requires careful analysis and clear institutional arrangements.
Another challenge is that management and monitoring capacity in many coastal localities remains limited, while coordination among relevant sectors—such as environment, agriculture, fisheries, and tourism—is not always sufficiently integrated. This calls for stronger institutional coordination and transparent management systems to ensure that financial resources are used effectively and for their intended purposes.
Towards sustainable financing for conservation
To effectively develop a payment mechanism for marine and wetland ecosystem services, many experts recommend implementing pilot projects in selected areas with favorable conditions, such as marine protected areas, coastal mangrove forests, or lagoons with high biodiversity value. These pilot initiatives can help assess feasibility, refine methodologies for ecosystem service valuation, and develop appropriate financial distribution mechanisms.
At the same time, strengthening the participation of local communities is essential, as they are the key actors directly involved in protecting and utilizing natural resources. When communities receive tangible benefits from conservation activities, they are more motivated to protect ecosystems and manage natural resources sustainably.
Developing comprehensive databases on marine and wetland ecosystems—including maps of ecosystem distribution, conservation status, and ecosystem service values—is also crucial to support policy formulation and implementation. Moreover, promoting international cooperation will help Viet Nam learn from countries that have successfully implemented payment mechanisms for marine and coastal ecosystem services.
In the long term, the development of a payment mechanism for marine and wetland ecosystem services will not only contribute to biodiversity conservation but also create sustainable financial resources for natural resource management. This approach represents an important step toward linking conservation objectives with economic development, while highlighting the critical role of nature-based solutions in Viet Nam’s sustainable development strategy.
