Kayaking  through the crystal waters of Lan Hạ, a small bay lying to the northeast  of Cát Bà Archipelago, 30 kilometres from the port city of Hải Phòng,  one has the opportunity to glimpse the white-headed langur, a species  endemic to the archipelago and now found nowhere else on earth.
 
The  Cát Bà langur, as it is commonly called, often sleeps in the caves and  seeks food around the mountains – leaves, fresh shoots, flowers, tree  barks and some fruits that are not palatable to humans. Visitors,  therefore, can have a chance to see them as they travel among the  islands. 
 
There  are currently just 60 langur individuals left, and the animals are  known to only live on the islands of Cát Bà, according to the Cát Bà  Langur Conservation Project.

The  langur has become a symbol for the archipelago. The Cát Bà langur  population is scattered around the islands in several isolated  sub-populations. Some of these include all-female groups with no access  to males and are therefore non-reproducing social units, according to  the project. 
 
Besides  the langur, the Cát Bà Archipelago has more than 3,800 other species of  insular and marine fauna and flora. Among them, 130 rare species are  named in the Việt Nam and World Red Lists, among which, 76 species are  found in the rare category of the IUCN, and 21 species are endemic.
 
With  the rich values of natural beauty and biodiversity of the Cát Bà  archipelago and shared marine ecosystem with world heritage Hạ Long Bay,  Hải Phòng City is working with Quảng Ninh Province to finalise a  dossier to nominate Hạ Long-Cát Bà as an expanded World Heritage Site.
 
Hạ  Long-Cát Bà is currently on the Tentative List at UNESCO and the  application will be sent to the Việt Nam cultural agency by February  next year.

“The  Cát Bà Archipelago is a highly bio-diverse centre with several  especially rare species which have universal value. It is considered the  most bio-diverse area in Việt Nam,” said professor Đỗ Công Thung from  the Institute of Marine and Environment Resources in a leadership  meeting held by International Union for Conservation of Nature (IUCN) in  Hải Phòng on May 5. 
 
“We  recognise the unprecedented joint efforts of the two localities [Quảng  Ninh Province and Hải Phòng City] in collaborating to renominate Hạ  Long-Cát Bà. The biodiversity is no longer restrained in the territorial  limit,” said Phạm Ngọc Thanh Hường, Culture Specialist from UNESCO Việt  Nam, at the meeting.
 
The  Hạ Long-Cát Bà Archipelago extension will be considered under two  criteria –aesthetic value and geomorphic and physiographic value, and  additionally two bio-diversity criteria, for a new World Heritage Site  (WHS) nomination.
 
UNESCO  has 10 criteria for selecting a WHS. Six of them are for cultural sites  and the other four are for natural sites. To be added to the list, a  site must be of "outstanding universal value" in at least one criterion.
 
In 1994, Hạ Long Bay was inscribed as a natural WHS under the criterion of aesthetic value and geology.
 
The  combined area of Hạ Long Bay and Cát Bà Archipelago is over 770 square  kilometres, in which Hạ Long Bay World Heritage accounts for 434 sq.km  including 775 islands and islets.
 
The  Cát Bà Archipelago is under close management of the three bodies – Cát  Bà National Park, the Management Board of Cát Bà Bay and the Management  Board of Cát Bà Heritage.
 
There  are currently different layers of environmental protection in Cát Bà,  which include a biosphere reserve with a core zone, buffer zone and  transition zone and a national park with special use area. Each has  specific management requirements and policies, according to Thung.
 
“Taking  the langur as an example. This species, listed as endangered, live  mostly in seven areas in Cát Bà; therefore, the Hải Phòng authorities  have made these seven areas strictly protected and bans any activities  that may cause harm to the living and breeding of langur,” said Thung.
 
“The  langur is a very sensitive species. If they smell humans nearby, or  even from a kilometre away, they hide themselves or run away, not to  mention the effect that construction activities have on the animals. It  is necessary to limit development projects here,” said Nguyễn Hoàng Trí.
 
Mass tourism – ‘not the ultimate purpose of nomination’
 
"Most  locations enjoy a tourism ‘boom’ after being recognised by UNESCO. But  it is crucial to note that increasing tourism, especially mass tourism,  is not the main aim of nomination," said Hường.
 
Việt  Nam tends to draw more tourists while some other places are trying to  cut down on the number of tourists or even stop tourism entirely, like  Santorini (Greece), Koh Khai Nok (Thailand), Machu Pichu (Peru) or the  whole of Bhutan, according to Cát Bà Langur Conservation project’s  manager, Neahga Leonard.
 
Currently,  Cát Bà welcomes around 1.7 million tourists per year, already more than  the number of tourists that many of these other places get. Cát Bà is  estimated to have 5-6 million tourists by 2020 and 8 to 10 million by  2030.
 
“The  ultimate purpose of nomination is not for tourism. Normally, we get the  title, the site becomes famous and we draw more tourists. Yet we are  making a big mistake, not only in Cát Bà, but in nine biosphere areas  and five world heritage sites in Việt Nam,” said Nguyễn Hoàng Trí,  general secretary of Việt Nam National Committee for the UNESCO  Programme "Man and Biosphere".
 
“The  tourism industry is only a means towards sustainable development.  Sometimes, we seem to turn the means into the purpose, leaving cement  structures, and not natural beauty, as the legacy for future  generations. It is tourism based on community that should be encouraged  and invested in,” said Trí.
 
“Sometimes,  we forget the main aim of nomination, which is to conserve the site.  Once the site is nominated, the country has to put in place national  responsibility and commitment to preserve the site for the international  community,” said Bài.
 
Conservation, a core driver of UNESCO recognition
 
Besides  mass tourism development, construction projects in Cát Bà are also a  big concern for non-governmental organisations and the conservation  community.
 
A high-end ecological tourism project was launched in Cát Hải district, Hải Phòng on May 14th.
 
Though  the project is implemented outside the core zone of the biosphere  reserve, the conservation community has concerns about its impact on the  environment and biodiversity of the region. This project and others of  its kind must be undertaken in a very careful manner.
 
“UNESCO  has strict rules on the presence of projects inside WHS that threaten  its outstanding universal values. We are confident that the relevant  authorities will put in place a planning process that ensures that  tourism does not threaten these values,” said Acting Country  Representative of IUCN Việt Nam, Jake Brunner.
 
“Many  of Việt Nam’s most beautiful coastal areas, including Cát Bà, are being  targeted for large-scale tourism development. Việt Nam badly needs  investment in tourism but this must be done in ways that don’t damage  what’s so special about these places, keeps tourists coming back, and  sustains jobs and revenue over the long term,” said Brunner.
 
As  per the 1972 world heritage convention of UNESCO, "the major aim of  nomination is to put the property into an international framework of  protection," said Hường.
 
“Nomination  is not only a matter of seeking an international title, but to preserve  the property, to allow future generations to enjoy it, along with the  natural and cultural resources that the country has to offer. This is  the aim of world heritage recognition,” she added.
 
“Tourists  come here because Việt Nam has a number of unique qualities that no  other place has, especially its natural beauty and culture; and those  things are sensitive, once they are damaged, we can’t get them back,”  said Leonard.
 
“Development on this line needs to be taken in a careful and cautious manner.
 
“Cát  Bà has a number of unique and special characteristics, especially  natural beauty, biodiversity and endemic species, which are the very  reasons [Việt Nam] is considering the expanded WHS nomination.
 
“We need to be very careful not to damage these particular aspects of Cát Bà,” said Leonard.
 
“The  key thing here is that there is no conflict between conservation and  development and tourism. People in the conservation community understand  very clearly the need for development and tourism. We encourage and  support it but development and tourism should be done in a long-term,  responsible and sustainable manner, a manner that follows laws and  international guidelines,” said Leonard.
 
“We  can learn from the Tràng An case [nomination for Tràng An in Ninh Bình  Province as a World Heritage Site] – working with investors for  sustainable development, persuading them to narrow their projects [in  protected areas],” said director of Việt Nam Cultural Heritage  Conservation Fund, and representative of Việt Nam National Committee of  UNESCO, Đặng Văn Bài.
 
“A  few years ago, when we were discussing the nomination of Tràng An as  World Heritage site, some disagreed with the nomination, but one of my  points was that if Tràng An is not nominated, then the limestone  mountains in Ninh Bình [where the site is located] would disappear over  the next five years due to rock quarrying in the area,” said Bài.
 
After Tràng An was recognised, the quarries were forced to halt operations and miners moved to other areas.
 
“This is an example of UNESCO’s active contribution to protecting and preserving WHS.
 
“In  the end, protecting heritage and pushing the economy is just a means to  our ultimate goal of sustainable development, for our country and for  the next generation.
 
“It  is crucial that we do not sacrifice heritage for economic benefit, yet  we also should not let development be hindered by heritage.”
