        从事生物多样性研究的科学家,目前正面临近退两难的境地,就是为限制人们进入生态资源丰富的热点地区而采取的必要的法规措施,可能也会同时妨碍科学家为了监控这些地区而进行的必要的研究活动。

         有人认为,强化与生态遗传资源获取和开发相关的法规,可能并非会对生态资源保护起到预期的效果。

Biodiversity law could stymie research

Tighter rules on accessing and developing genetic resources may be counterproductive for conservation.

Natasha Gilbert

Scientists who study the world's biodiversity are facing a dilemma: proposals to regulate access to the riches of ecological hotspots may hamper the research needed to monitor these areas.

The warning comes as signatories to the Convention on Biological Diversity (CBD) begin negotiating ways to strengthen the treaty's legal framework and goals, which include conserving biodiversity and promoting the sustainable use of natural resources (see 'Key questions'). A crucial part of that effort, discussed last week at a meeting in Montreal, Canada, is the reform that is generally regarded as the least effective aspect of the CBD: deciding who can exploit valuable genetic resources, such as plants that produce potential pharmaceuticals, and who should benefit financially.

Many developing countries complain that this aspect of the CBD relies on voluntary guidelines, rather than clear international legislation. This makes it difficult to police how genetic resources are used, and to ensure that countries are paid fairly if commercial products are developed from their resources. Moreover, national regulations governing access and benefit sharing can vary enormously between countries, confusing both commercial and non-commercial researchers.

The negotiators aim to produce a legally binding framework that resolves all these problems, which will be considered for adoption under the CBD at a meeting of the convention's signatory countries in October in Nagoya, Japan.

But tougher regulation could come with a cost, warns David Schindel, an invertebrate palaeontologist and executive secretary of the Consortium for the Barcode of Life, an inter-national initiative to identify species using short genetic sequences, based at the Smithsonian Institution in Washington DC. "We are very concerned that it will become more restrictive," he says. In some cases, it can already take at least two years and reams of paperwork to agree the terms on which research can be conducted, specimens exported and profits shared. "You could go through a field season collecting specimens and then the government says they are going to hold on to them because you don't have the right permission," he says. "The specimens sit on a dock, rot and are lost."

David Oren, coordinator of biodiversity in the ecosystems management office of Brazil's Ministry of Science and Technology, agrees that the framework must strike a balance between protecting a nation's intellectual property and not impeding research. He says that access and benefits legislation introduced by Brazil in 2002 "essentially stopped" research on biodiversity in the country, as it restricted the exchange of specimens between institutions. The rules have since been relaxed to make a clear distinction between basic and commercial research, making it easier for academics to study biodiversity in Brazil, but many other countries, including India, still have highly restrictive regimes, says Schindel. He hopes that the new CBD framework will clarify the situation, although some experts say that defining commercial research will not be easy — it is increasingly common for academic scientists to make patent applications based on their research, for example.

Ahmed Djoghlaf, executive secretary of the CBD, points out that an improved international framework should also benefit companies, giving them more confidence to invest the time and money required to develop products from natural resources. "What company would invest now if they don't know what a country's legislation will be like in 20 years' time?" he asks.

Other key sticking points in the negotiations include defining exactly what a genetic resource is, and whether the regime should be restricted to plants or should also include animals and pathogens.

Negotiators must reach a consensus on the framework at a meeting in March in Cali, Colombia, the deadline for finalizing the text for consideration at Nagoya. There's a lot at stake, says Djoghlaf. "If we get agreement, it will be a major breakthrough in the sustainable development and environmental movement."
