Research Workshop: Greening of Cities; Auckland, New Zealand; 30 November 3 December 2012

1950年，世界上只有不到30%的人口居住在城市。 这一数字在2000年增长到47%（28亿人），预计到2025年将增长到60%。 为适应这一增长所需的功能性基础设施服务是惊人的。 如果什么都不做，对自然生态系统的潜在影响可能是灾难性的，无论是在当地还是在全球。 为了避免这种情况，需要多个学科的专业知识（工程，生态，景观设计和城市规划）和新的城市基础设施思维方式。 “城市绿化”研究讲习班将汇集来自地球仪多个领域的专家。 它们将确定需要解决的一系列问题并确定其优先次序，并评估找到解决办法所需的现有知识是否充分。 他们将确定绿色技术，如绿色屋顶、绿色墙壁、人工湿地、绿道、绿色街道和其他有望解决这些问题的技术。 研讨会与会者将确定量化绿色基础设施潜在功能的方法，如清洁水，气候变化和过滤空气，以及来自这些服务的多重价值，包括改善人类健康，减少能源消耗，移动人员和促进可持续经济发展。 与会者还将确定来自绿色城市基础设施的重要无形价值，例如增加野生动物多样性，视觉质量和其他对城市生活质量的贡献。 这些问题的影响将在地方和全球范围内进行审查。 为了了解将绿色基础设施纳入城市的潜力，研讨会与会者将研究来自世界各地的选定案例。 讲习班的成果将是一套研究需求和战略，其中将包括合作研究工作，这些工作将提供所需的知识，以更好地了解绿色基础设施如何在数量和质量上造福于建筑环境及其社区。 城市为人们提供了重要的社会和经济机会，这就是为什么世界各地的城市正在以惊人的速度增长。 随着这种增长，我们需要确保城市是健康的生活场所，通过城市基础设施提供清洁的水，交通和能源，同时确保人们拥有清洁的空气和健康的生活和工作场所。为了实现负担得起的、可持续的基础设施，科学家和工程师正在研究绿色技术和再生系统，如绿色屋顶、绿色墙壁、人工湿地和绿道。 为了使城市规划者和其他城市建设者采用这些新的绿色技术，专家必须能够通过研究和实践经验证明这些新技术的价值以及如何加以实施。 本次研讨会的目的是聚集来自世界各地不同领域的专家，研究城市面临的问题，确定潜在的绿色基础设施解决方案，并确定证明其价值所需的研究。

In 1950, less than 30 percent of the world's population lived in cities. This number grew to 47 percent in the year 2000 (2.8 billion people), and it is expected to grow to 60 percent by the year 2025. The functional infrastructure services needed to accommodate this growth is staggering. If nothing is done, the potential effect on natural ecosystems could be catastrophic, both locally and globally. To avoid this will require the expertise of multiple disciplines (engineering, ecology, landscape architecture and urban planning) and new ways of thinking about urban infrastructure. The Research Workshop, Greening of Cities, will bring together experts from multiple fields, across the globe. They will identify and prioritize the range of issues that need to be addressed and assess the sufficiency of existing knowledge needed to find solutions. They will identify green technologies, such as green roofs, green walls, constructed wetlands, greenways, green streets and others that hold promise for solving these problems. Workshop attendees will identify ways of quantifying the potential functionality of Green Infrastructure, such as cleaning water, climate modification and filtering air, as well as the multiple values that come from these services, including improving human health, reducing energy consumption, moving people and increasing sustainable economic development. The attendees will also identify important intangible values that come from green urban infrastructure, such as increased wildlife diversity, visual quality and other contributors to quality of urban life. The implications of these issues will be examined at both a local and global scale. In order to understand the potential for incorporating Green Infrastructure into cities, workshop participants will examine selected case examples from around the world. The result of the workshop will be a set of research needs and strategies that will include collaborative research efforts that will provide the knowledge needed to better understand how green infrastructure can benefit the built environment, both quantitatively and qualitatively, and its communities. Cities provide important social and economic opportunities for people, which is why cities around the world are growing at a phenomenal rate. With such growth, we need to ensure that cities are healthy places to live, providing clean water, transportation and energy through urban infrastructure while ensuring people have clean air and healthy places to live and work. In order to achieve affordable, sustainable infrastructure, scientists and engineers are looking at green technologies and regenerative systems, such as green roofs, green walls, constructed wetlands and greenways. For these new, green technologies to be adopted by urban planners and others who build cities, experts must be able to demonstrate the value of these new technologies and how they can be implemented, both through research as well as practical experience. The purpose of this workshop is to gather experts from different fields around the world to examine the problems cities face, to identify potential green infrastructure solutions and to identify the research needed to demonstrate their value.
