解读棕地修复Understanding Brownfield Remediation Rapid economic growth and industrial restructuring

in China have produced growing numbers of abandoned and often contaminated sites — known as brownfields — in major urban areas. Brownfield redevelopment is an urban land use strategy based on the principles of sustainable development: it relieves environmental pressure and resolves the glaring contradictions between urban land idleness and urban sprawl, seeking to turn disused and derelict land into viable industrial, residential or recreational areas. A newcomer to this discipline, China still has much room for improvement.

Putting sustainable brownfield redevelopment at the heart of planning strategies for major Chinese cities would deliver long-term improvements in environmental quality, farmland protection, public health and safety, housing and job growth, tax revenue and, ultimately, economic health.

The following chapters introduce the historical background to brownfield redevelopment, from the initial definitions of brownfield to its general acceptance in western countries. Recent developments on brownfield issues in China, including the main institutional arrangement, such as relevant policies and regulations, barriers and stakeholders, are outlined to provide insight on the potential opportunities that brownfield redevelopment could provide in the Chinese market.

全球视野:棕地重建是实现可持续发展的关键Brownfield Redevelopment: A Global Perspective高明正/文 By Matthew Ko

Economic structural changes and the decline of traditional industries has led to a rise in derelict sites and the subsequent decline of neighborhoods. These contaminated vacant lands, which were first labeled “brownfield” in the United States, pose threats not only to the environment but also to the economic and social health of a city. While demands for revitalized urban areas and a better quality of life continue to grow, the redevelopment of these brownfields that blight the urban landscape has received particular attention from policymakers and urban planners. Governments from developed economies have sought better understanding on brownfield issues since the late 1970s and significant efforts have been made to foster redevelopment.

The overarching objectives associated with the management of brownfields have evolved over the past few decades, shifting from an initial focus on managing health and environmental risks to developing and implementing mechanisms for stimulating economic development.

More stakeholders are raising their expectations of redevelopment in an effort to meet a broader range of environmental, social and economic objectives that fall under the umbrella of “sustainable development.”

Taking into account the scarce availability of greenfields for future development, the protection of limited natural and land resources and the urgent need to revitalize deteriorating neighborhoods, this chapter looks at how brownfield remediation and redevelopment could be a vital tool in achieving sustainable development.

经济结构的转变和传统工业的衰败导致了废弃用地的增加,随之

而来的是周边社区的衰退。在美国,这些受污染的闲置场地首次

被贴上“棕地”这一标签。它们不仅对环境造成危害,还威胁着城

市的经济发展和社会健康。当人们对复兴市区的需求越来越强

烈,对生活品质的追求越来越高时,开展棕地重建,美化市区景

观的呼声慢慢引起了城市决策者和规划者的特别关注。20世纪70

年代后期,发达国家对棕地议题的认识和理解逐渐加深,也采取

了不少促进棕地重建的有效措施。

在过去数十年,棕地管理的首要目标已经发生了改变:从初期的

关注人类健康和环境风险转变为后来的通过制定和实施相应机

制来刺激经济发展。

利益相关者对棕地重建的期望越来越高,他们希望在更大范围内

实现环境、社会和经济的可持续发展。

考虑到未来绿地资源的稀缺性,保护有限的自然和土地资源的迫

切性,振兴颓败社区的急切性,本章将讨论棕地修复与重建如何

作为关键方法,帮助实现可持续发展。

1.1 理解棕地的复杂性

棕地涉及各类型复杂的社会、经济和技术问题,要全面了解这个

议题,需要运用多个学科的理论、概念和方法。

根据美国环境保护局的定义,棕地属于不动产,这些不动产在其

扩展、振兴和再开发时受到现实或潜在有害物质和污染物的影响

(美国环境保护局,2002)。这一广泛的棕地定义被世界众多地方

采用,决策者和实践者可以灵活地把棕地纳入环境和经济问题

(Yount,2003)。在欧洲,棕地的概念从潜在的污染土地延伸到

所有开发过的土地和建筑(Alker等,2000)。由此可见,棕地重

建涉及多个学科,需要从不同角度加以考虑。

1.1 Understanding the Complexities of Brownfield SitesBrownfields lie at the nexus of a variety of socio-economic and technical issues. Understanding the complex dynamics of brownfields requires theories, concepts and methods that have traditionally resided within discrete academic disciplines.

According to the definition made by the U.S. Environmental Protection Agency, brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant or contaminant (USEPA, 2002). This broad-brush definition of brownfields, which has already been employed in many parts of the world, gives policymakers and practitioners the flexibility to address brownfields as both an environmental and economic problem (Yount, 2003). The definition of brownfields was further extended in Europe from potentially contaminated properties to any previously developed land and buildings (Alker et al., 2000). These wide definitions indicate that brownfield redevelopment is a multidisciplinary issue that needs consideration from different angles.

The concept of “brownfields” may refer to any contaminated, abandoned or underdeveloped land; such land existed since the Industrial Revolution began in the mid 18th century. More specifically, the historical roots of brownfield issues can be traced back to events such as the Love Canal Disaster in Niagara Falls, New York, that began in 1978, when the local government covered up a hazardous waste dumpsite for settlements and continues to adversely affect local residents to the present day (Colten and Skinner, 1996). The publicity generated by this and similar events has drawn global attention to the fact that poor management when developing brownfield sites or previously developed properties could have catastrophic consequences for the entire community (Gorman, 2003).

In this sense, the term “brownfields” is a relatively new name for a long-existing problem. Brownfields are commonly associated with old industrial sites as a legacy of industrialization (Grimski & Ferber, 2001): for decades now, businesses have been leaving urban areas to build on cheaper real estate or to cluster in industrial parks. Many of these enterprises were polluting industries that left behind abandoned structures containing pollutants or hazardous waste, either in storage or in the local soil and groundwater, and this of course had the potential to cause negative impacts to human health and to the environment. The decision of what to do with abandoned and contaminated industrial sites has been much debated. In the past, such facilities were primarily fenced off from the public and left alone. Cleanup was always an option, but liability concerns made it difficult to redevelop a site as no one wanted to take responsibility for the cost of cleanup or be liable for any damage to private property, ecosystems or human health (Bookspan, 1991; Hird, 1994).

While the cost of cleanup could easily exceed the economic value of the site, there was an overriding need to address increasing community concerns about the risks posed by brownfields. Therefore, the initial focus of policymaking frameworks in western countries was generally on safeguarding public health and reducing the environmental risks associated with contamination (De Sousa, 2009). These frameworks were designed to achieve four major objectives:

- Identify the sites that posed a potential risk to human health and the environment;

- Place the most contaminated sites on a priority list;- Remediate the contaminated sites;- Ensure the party responsible for contamination

paid for cleanup, and should the responsible party be unknown, to cleanup with cost covered by the government or taxpayer.

Eventually, the U.S. Government and later European governments dedicated considerable effort towards developing their own regulations and guidelines on the management, and particularly the remediation and decontamination, of brownfields (Alker & Mcdonald, 2003; Yount, 2003). As part of this process, formalized mechanisms were gradually established to clean up contaminated brownfields for which nobody assumed responsibility.

棕地可以指任何受污染的、废弃的或开发不足的土地,这些土地

在18世纪工业革命时期就出现了。说得更具体一些,棕地议题的

历史根源可以追溯到当时发生的几件大事。例如发生在美国纽约

州尼亚加拉大瀑布的“拉夫运河”事件。该事件始于1978年,当

地政府填埋了有害废物倾倒场地,将其改建成安置区,导致这些

物质至今仍然对当地居民的健康和生活造成负面影响(Colten &

Skinner,1996)。媒体对此类事件的宣传报道引起了全球关注,

人们逐渐意识到若对棕地或已开发土地管理不善,将对整个社区

造成灾难性后果(Gorman, 2003)。

由此看来,土地污染问题由来已久,“棕地”是这一老问题的新

说法。棕地通常与工业化时代遗留下来的废旧工业用地相关

(Grimski & Ferber,2001):近几十年来,许多企业逐渐搬离市中

心,选择更便宜的土地或往工业园区扎堆,这些企业大多属于污

染严重的行业。污染或有害物质不仅存在于其废弃的建筑物,也

残留于仓库、当地的土壤或地下水,并对人体健康和环境质量构

成危害。因此,目前对这一类型用地的处理方法讨论很多。以往

多采用设施将污染物与公众隔离,修复也是常用的方法,但这一

方法的困难之处在于涉及责任体制,因为没有主体愿意负担修

复成本或承担破坏私有财产、生态系统和人类健康的法律责任

(Bookspan, 1991; Hird, 1994)。

当棕地的修复成本高出其本身的经济价值时,最重要的是减轻

社区居民对棕地风险的忧虑。为此,西方国家在建立决策框架时

首先关注的是保护公众健康和减低由污染引起的环境危害(De

Sousa,2009)。通过这些决策框架有望达成以下4个主要目标:

- 识别哪些场地对人类健康和环境造成潜在威胁;

- 把污染最严重的场地列入《优先控制场地名录》;

- 修复受污染场地;

- 确保责任方承担修复费用,在没有责任方的情况下,由政府或

纳税人出资。

美国政府及欧洲多国政府为建立适合自身条件的棕地管理

规程和指南付出了诸多努力,尤其在棕地修复方面 (Alker &

McDonald,2003; Yount,2003)。在此过程中也为缺乏责任

方的棕地修复建立起规范机制。

1.2 棕地重建之路

由于大多数棕地位于城镇和城市的重要地带,所以各级政府的决

策者都希望能变废为宝。不过,棕地通常建有现成的基础设施,

如道路、电线和污水下水道系统,所以重建工作需要经历漫长过

程,才能盘活城市衰退区,同时保护绿色用地免遭新的开发。

图1-1“拉夫运河”是一个尚未完成的项目,该项目计划建造一条运河连接安大略湖、社区公园和沿河

住宅。项目被搁置后,未完工的运河逐渐蓄满水。在20世纪30年代,运河成为了州倾倒场地。在1942

年,虎克电化学公司获尼亚加拉电力发展公司许可往运河倾倒废弃物。截至1953年,该场地仍在运

营,虎克公司已往河中倾倒了约2万吨化学废料。此后,场地被关闭,并于其上填土、种菜。但是,当地

政府隐瞒了这一情况,居民开始沿河而居。直到1978年,当地媒体披露了这里当年曾是倾倒场地的信

息,并首次就居民的健康问题展开调查

Figure1-1 Love canal was an unfinished project that planned to construct a canal that connects Lake Ontario with a community of parks and homes along the canal. With the project abandoned, the unfinished canal gradually filled with water. In the 1930s, the canal became a dump site for the State. By the 1940s, Hooker Electrochemical Company was granted permission by the Niagara Power and Development Company in 1942 to dump wastes in the canal. This dumpsite was in operation until 1953 with 21,000 tons of chemicals added. The canal was covered with soil upon closure of the dumpsite and vegetation began to grow atop. The local government covered up this issue and urban dwellers began to settle along the covered canal. Until 1978, the dumpsite was discovered and investigated by the local newspaper with health problems were first raised

In addition to cleaning up the contaminated and abandoned brownfield sites, these initiatives encourage redevelopment that leads to profitable business operations, revitalized communities with better socio-economic environments and other financial incentives. Through various forms of assistance such as grants, tax reductions, loans and easier development approvals, brownfields have turned out to provide opportunities for investors, developers and entrepreneurs to buy undesirable properties at below market price, clean them up at a lower cost, obtain financial, regulatory and technical assistance for the developments and make a desirable profit (Verbit, 2001). 1.3 Achieving Sustainability in Brownfield Redevelopment If sustainable development is defined as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs (Brundtland, 1987),” the presence of brownfields represents a good example of how past activities have come to compromise this generation. For many communities, brownfields have become a symbol of economic growth that does not occur within a sustainability framework (Bjelland, 2004). In the meantime, as more and more people live in cities, which in turn continue to expand topographically, demographically and economically, it is becoming clear that a sustainable approach to urban development is necessary to help safeguard communities against poverty, social inequality and environmental degradation. As a result, it makes sense to redevelop brownfield sites for environmental, social and economic reasons, so that they can make urban development:

- More productive, stable, innovative and economically equitable;

- More capable of catering to social needs, especially in the areas of health services and of preserving social values, traditions, heritage, and culture;

- More sensitive to ecosystems and have minimal or at least controllable impacts on the natural environment.

Various studies have sought to identify the potential benefits of brownfield redevelopment in achieving sustainability. Some examples of these benefits are outlined in Figure 1-2.

1.2 The Way To Brownfield RedevelopmentAs brownfield sites are frequently located in prime areas of our towns and cities, it is understandable that policymakers at all levels of government would be interested in getting them back into productive use. And since they are commonly serviced by readily available infrastructure, such as roads, power lines and sewage systems, their redevelopment could clearly go a long way towards revitalizing deteriorating urban areas and preserving greenfields from new development.

However, although regulations have successfully facilitated the remediation of brownfield sites, interest on the part of developers, landowners and other private-sector stakeholders in putting these sites back into productive use has tended to be minimal because of the fear that such sites may be too expensive, too time-consuming or too risky to redevelop profitably. Instead, they have remained focused on the development of greenfields, which are usually farmlands and undeveloped wilderness, through building low-density subdivisions and this has led to urban sprawl. While suburban development continuously encroaches on precious agricultural land, brownfields within city districts or neighborhoods remain vacant and lead to various socio-economic problems. Nevertheless, while it is obvious that brownfield redevelopment would be beneficial to the community, it has been difficult for governments to redevelop the vast number of brownfield sites in urban centers without the assurance of private investment. To effectively attract investors, governments are having to bring about a better competitive position for them by implementing a wide range of financial, fiscal, legal and policy incentives, instead of direct regulations, in order to overcome reluctance to redevelop these sites (Thornton et al., 2007). In developed economies, governments have implemented a variety of initiatives since the 1990s to lessen the costs and risks associated with brownfield redevelopment (Syms, 1997).

尽管相关的规章制度为棕地修复提供了保障,但发展商、土地所

有者和其他私营利益相关者担心投入太高、周期太长、风险太

大,因此他们对这一部分土地的兴趣不大。相反,他们仍通过兴

建低密度住宅小区来集中开发绿色用地,这些土地多半是农田和

未开发的荒地,这导致了城市扩张。一方面,郊区的开发逐渐吞

噬宝贵的农田;另一方面,市区和社区的棕地却仍然闲置着,这种

情况引起了不同的社会经济问题。

尽管棕地重建对社区的益处显而易见,政府却很难在没有私人投

资参与的情况下在市中心实施大量的棕地重建。为有效吸引投资

者,政府并没有制定直接的法律法规而是推出了大量的金融、财

务、法律和政策激励,为投资者创造更有利的竞争条件,让他们自

愿进行棕地重建(Thornton等,2007)。从20世纪90年代开始,发

达国家的政府部门采取了许多积极措施,以降低棕地重建的成本

和风险(Syms,1997)。

除了修复受污染和被废弃的棕地外,上述举措还鼓励投资者在

重建后的场地开展商业活动,在更好的社会经济环境和其他财政

激励下复兴社区。投资者、开发商和企业主可获得不同形式的帮

助,如拨款、减税、贷款、较简易的开发审批程序等,他们通过这

些方式以低于市场平均价购入棕地,以较低的成本进行修复,取

得开发所需的财政、制度和技术协助,创造可观的经济收益。

1.3 实现棕地重建的可持续发展

如果可持续发展的定义是“既满足当代人的需求,又不损害后代

人满足其需求的能力”(Brundtland,1987),那么棕地的存在是

一个很好的例子,见证了过去的经济活动如何损害了我们这一代

人的利益。棕地对很多社区而言,是一个存在于可持续发展框架

以外的经济发展象征(Bjelland,2004)。同时,随着城市人口越

来越集中,在地理上、人口上、经济上的扩张也会不断持续,从而

令我们更清晰地认识可持续发展的必要性。它可以帮助社区摆脱

贫穷、社会不公和环境恶化。因此,围绕环境、社会和经济等原因
