The UNESCO Recognition Process: Ha Long Bay as a World Natural Heritage Site

Ha Long Bay is one of the world’s most renowned natural heritages, admired and cherished by millions of travelers both domestically and internationally. The journey to achieving the title of World Natural Heritage was a long and arduous process, yet it remains a source of immense glory and pride for Quang Ninh province and Vietnam as a whole. This article explores the timeline and the process behind UNESCO’s recognition of Ha Long Bay as a World Natural Heritage site, covering the years from 1991 to 2000.

1991: The Vietnamese government approves the drafting of the Ha Long Bay nomination dossier

Recognizing the universal value of Ha Long Bay and the aspiration for global recognition and celebration, the Government of Vietnam officially authorized the preparation of the Ha Long Bay nomination dossier for submission to the World Heritage Committee on December 21, 1991. This was a critical first step in affirming the stature and significance of Ha Long Bay on the international stage.

To prepare the dossier, the Ha Long Bay Management Board collaborated with various domestic and international agencies, units, and experts to conduct essential tasks, including: surveying, researching, collecting, synthesizing, and compiling scientific data on the Bay; establishing a conservation and sustainable development plan; and designing and printing the documentation according to UNESCO’s requirements. These efforts spanned two years, from 1991 to 1993.

The nomination dossier consisted of two main parts: Part I provided a comprehensive overview of the Bay’s geography, geology, ecology, history, and culture; Part II outlined the management plan, detailing specific goals, principles, and measures. The dossier was produced in English and French, supplemented by maps, photographs, and reference materials.

The nomination was submitted to UNESCO in 1993 and reviewed during the 18th session of the World Heritage Committee in Phuket, Thailand, in 1994. After reviewing reports from experts and Vietnamese representatives, the Committee highly valued the universal significance of Ha Long Bay and decided to grant it World Natural Heritage status for its aesthetic beauty.

This achievement was the result of immense effort by the Ha Long Bay Management Board, along with numerous agencies, organizations, and experts. It stands as a point of pride for both Quang Ninh and Vietnam, as it represents a natural treasure recognized and honored by the world. It also serves as a driving force for the ongoing protection and sustainable development of Ha Long Bay for future generations.

To be recognized as a World Natural Heritage site for aesthetic value, Ha Long Bay had to meet UNESCO’s criterion (vii):

Represent superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance;
Contain superlative natural phenomena or areas of exceptional natural beauty and aesthetic importance;
Contain areas of exceptional natural beauty or aesthetic importance resulting from related geological or biological processes.

As a UNESCO-recognized aesthetic heritage site, Ha Long Bay is famous for its unique and mysterious landscape, featuring thousands of limestone islands that create dramatic, vibrant vistas. The Bay is also home to magnificent caves, housing diverse and beautiful stalactites. Beyond its rich and varied ecosystem, home to many rare and endemic flora and fauna, Ha Long Bay is steeped in the legends, history, and culture of the Vietnamese people, elevating it to a natural heritage of high cultural value.

1999: The Ha Long Bay Management Board continues to build and submit a scientific dossier to UNESCO

Following its recognition for aesthetic value, the Ha Long Bay Management Board continued to research and explore the Bay’s other dimensions. Recognizing the Bay’s exceptional universal geological and geomorphological values, the Board sought further recognition from UNESCO for these criteria.

To achieve this, the Management Board continued to collaborate with domestic and international agencies and experts to conduct investigations, research, data collection, and compilation, while refining the dossier according to UNESCO’s standards. The scientific dossier for Ha Long Bay was finalized and submitted to UNESCO in 1999.

The dossier consisted of three parts: Part I: General introduction to Ha Long Bay; Part II: The exceptional values of Ha Long Bay; Part III: Conservation and sustainable development plan. Part II was notably enhanced to include geological and geomorphological values in accordance with the standards of the Convention Concerning the Protection of the World Cultural and Natural Heritage.

Accordingly, Ha Long Bay is recognized as one of the most complex and diverse areas of limestone formation in the world. These limestone structures were shaped by tectonic processes occurring over billions of years. Ha Long Bay serves as a witness to sea-level fluctuations throughout the Earth’s evolutionary history, providing living evidence of global climate change. These geological features include distinct columns, caves, coastal structures, coral reefs, and sandy beaches.

To be recognized as a World Natural Heritage site for geological and geomorphological value, Ha Long Bay had to meet UNESCO’s criterion (i):

Represent major stages of Earth’s history, including the record of life;
Represent significant ongoing geological processes;
Represent outstanding or unique geological and geomorphological features;
Represent outstanding examples of geological processes occurring within ecosystems and biological communities.

Ha Long Bay was subsequently recognized by UNESCO for its geological and geomorphological heritage due to the development of its Karst limestone topography over billions of years. These forms are the result of tectonic shifts, deformation, uplift, erosion, dissolution, and sea-level changes. As one of the regions reflecting sea-level variations from the Cretaceous period to the present, Ha Long Bay stands as a living testament to global climate change. Furthermore, the interplay between geological and biological processes has created a rich and diverse ecosystem.

The Year 2000: UNESCO designates Ha Long Bay as a World Natural Heritage site for the second time, recognizing its outstanding geological and geomorphological values.

Following the submission of the Ha Long Bay dossier, UNESCO dispatched expert delegations to Quang Ninh to conduct on-site surveys, provide guidance, and evaluate the nomination. These experts offered valuable feedback and recommendations to further refine the documentation, while concurrently offering positive assessments that affirmed the global significance of Ha Long Bay.

During the 24th session in Cairns, Australia, the World Heritage Committee reviewed and appraised the Ha Long Bay dossier after hearing reports from the on-site survey teams. On December 2, 2000, UNESCO officially recognized Ha Long Bay as a World Natural Heritage site for the second time, honoring its exceptional geological and geomorphological values.
