Valuing Wetlands in China

At first glance, coastal mudflats can seem grim and desolate places with little obvious economic value.  It is therefore not surprising that these areas have often been considered by planners, and the public, to be suitable for reclamation projects and development.

Over the past 50 years in China, 60% of temperate coastal ecosystems, 73% of mangroves and 80% of coral reefs have been lost mostly due to economic development. Only 24% of coastal wetlands have been legally designated as protected areas, much lower than the mean wetland protection rate of 43.5% across China, and coastal wetlands in China’s most economically developed provinces/municipalities – such as Zhejiang, Jiangsu, Tianjin, and Shandong – are hot targets for development projects.

This rapid development has not come without costs. Thanks to studies such as the Blueprint for Coastal Wetlands in China, we now know that many of the decisions to develop these coastal areas have neglected the significant benefits of wetlands – so called ecosystem services – including helping to prevent and mitigate flooding and storm surges, regulating climate change by storing carbon, purifying water and providing sustainable livelihoods for local people, as well as providing invaluable habitat for millions of migratory shorebirds as they migrate to and from their breeding grounds in the Arctic and their wintering grounds in the southern hemisphere.  Such ‘natural capital’ is not reflected on most countries’ balance sheets but, nevertheless, its erosion undermines the ability to achieve sustainable economic growth.

One of the six recommendations contained in the Blueprint was the need to carry out publicity and education activities about wetland conservation, raising awareness and involving the public in protecting coastal wetlands and migratory birds.

That is why, this week, the Wetland Conservation and Management Office of the National Forestry and Grassland Administration in partnership with the Paulson Institute, the Lao Niu Foundation and the Mangrove Conservation Foundation, launched a new project to set up Wetland Education Centres across China.

The project, due to run for three years, will draw on national and international best practice, including from Mai Po Nature Reserve in Hong Kong, Guandu Nature Reserve in Taiwan and Sungei Buloh Wetland Reserve in Singapore as well as wetlands in Japan, Korea and Wildfowl and Wetlands Trust reserves in the UK.

The objectives are to establish:

  • A standard system for wetland education centres in China
  • Three to five demonstration wetland education centres within three years
  • A professional network for wetland education centres in China and to provide support for the establishment and development of further wetland education centres

This project will help build and strengthen public awareness about the value of China’s remaining coastal wetlands and underpins the recent announcement by the Chinese government to ban all further commercial land reclamation along the coast.

Professor Lei Guangchun of Beijing Forestry University delivered a comprehensive overview of wetlands in China and it was great to see Chris Rostron of the Wildfowl and Wetlands Trust (WWT) addressing the meeting to relay some of their experience in bringing wetland education to the public.

It’s heartening to see China’s top level policy announcements being backed up by the less high-profile but arguably more important, initiatives on the ground to raise awareness about the value of wetlands and the need to protect them.

And it’s not only in China that the value of wetlands is being recognised.  At the end of August, the government in Sri Lanka approved recommendations to protect and restore the urban wetlands of the capital, Colombo, after a study by The World Bank and WWT Consulting showed that benefits included:

  • Flood damage mitigation (without the wetlands, it was modelled that a 1 in 100 years flooding event could happen every year)
  • The wetlands provided cooling for the city of up to 5 degrees Celsius in the summer
  • Providing a home for >250 species of wildlife, including the endangered Fishing Cat
  • Air and water pollution mitigation
  • Food security for the urban poor
  • Places for recreation, education and tourism
  • Carbon sequestration

In total, these benefits were calculated to be worth 8.8 million RS (GBP 41,500, USD 54,000, CNY 370,000) per hectare per year.

On 28 August the Sri Lankan cabinet approved the recommendations and will designate the remaining wetlands as protected areas as well as setting up a dedicated management body to ensure they are managed effectively.  What a great example!

 

 

 

Baer’s Pochard breeds successfully at Hengshui Hu

At 1748 local time on 28 May 2018, Li Feng, a researcher and bird surveyor from Hengshui University found, photographed and videoed a female BAER’S POCHARD (Aythya baeri) with ducklings at Hengshui Hu National Nature Reserve in Hebei Province, China. This is the first confirmed breeding of the “Critically Endangered” diving duck anywhere in the world in 2018 and is almost certainly a direct result of conservation efforts by the local government and nature reserve staff, supported by the Sino-German Hengshui Lake Conservation and Management Project

The breeding success follows hot on the heels of the first international workshop of the Baer’s Pochard Task Force at Hengshui Hu in March 2018 and the subsequent commitments from the local government and local nature reserve to manage the lake for the benefit of this beautiful diving duck.

Baer’s Pochard (Aythya baeri) is a poorly known migratory diving duck that was formerly widespread in eastern Asia.  Since the 1980s it has suffered a precipitous decline throughout its range, estimated to be >90%, and fewer than 1,000 birds now survive in the wild, making it rarer than the Giant Panda.  Since 2012 it has been classified by the IUCN as “Critically Endangered”, meaning it is just one step away from extinction in the wild.  In the last five years it has become clear that Hengshui Hu in Hebei Province is the most important known site in the world for this species with more than 300 recorded during spring migration in 2017, several overwintering and a few pairs spending the summer.  However, due to a combination of fluctuating water levels during the breeding season, illegal egg collection and disturbance by electro-fishermen and tourist boats, there has been no recent evidence of breeding.

It was back in March 2017 that I visited Hengshui Hu, as part of the Sino-German Hengshui Hu Project run by German Development Bank, KfW, to to help train Hengshui University and nature reserve staff about waterbird monitoring and identification of Baer’s Pochard.  At that time I could not have dared dream that there would be breeding success a little over a year later.

Since then, the local groups have been systematically counting waterfowl, in particular Baer’s Pochard, on a weekly basis, helping to build up a better picture of how the lake is used by Baer’s Pochard and other waterbirds.  At the same time, a series of targeted conservation actions have been initiated, including declaring the likely favoured breeding area as a seasonal fully protected zone, compensating fishermen who could no longer fish in the protected zone, clamping down on illegal activity including illegal fishing and egg collection, stabilising the water level during the breeding season to avoid nests being flooded, and beginning a public information campaign to raise awareness about the global importance of Hengshui Hu for Baer’s Pochard.

Public information is crucial to help enthuse the local people and engender a sense of pride that they have such an endangered bird in their community

Just two months ago, the international spotlight shone on Hengshui Hu when, on 19-20 March 2018, delegates from ten countries gathered for the first international workshop on the conservation of the Baer’s Pochard under the auspices of the East-Asian Australasian Flyway Partnership (EAAFP).  Delegates from Bangladesh, China, Democratic People’s Republic of Korea, India, Japan, Mongolia, Myanmar, Republic of Korea, Russia and Thailand heard from senior Chinese local and national government officials, academics and international experts, discussed urgent conservation priorities and agreed the “Hengshui Declaration”. 

The actions by the local nature reserve and Hengshui University, enabled and reinforced by the political will shown by the local government, have undoubtedly created the conditions for successful breeding in 2018 and, in another demonstration of local commitment, more than 40 volunteers from Hengshui University have already set up a group to monitor the progress of these, and hopefully more, Baer’s Pochard ducklings. 

The positive results from Hengshui, coming so quickly after the concerted actions to support Baer’s Pochard, are deeply heartening and demonstrate that local conservation actions can deliver results.  And although there is a very long way to go to secure the future of this endangered species in the wild, successful breeding represents a positive step forward for the conservation effort.

Big congratulations to the local government, the local nature reserve, especially Mr Yuan Bo and Ms Liu Zhenjie, and to Hengshui University, in particular Dr Wu Dayong and Li Feng, and to everyone else involved, including Professors Ding Changqing and Lei Guangchun and Dr Wu Lan at Beijing Forestry University, Guido Kuchelmeister, Matthias Bechtolsheim and John Howes from the KfW project, Rich Hearn at WWT, Hyeseon Do from EAAFP and many more.
