Abstract

This paper summarizes an urban and regional planning case study concerning urban growth in relation to biodiversity in the city of Bogotá, Colombia. The case study is the third phase of an ongoing research project_the Hotspot Cities Project_at the McHarg Center for Urbanism and Ecology at the University of Pennsylvania. The first phase involved an audit of land use in the world’s biodiversity hotspots in relation to the Convention on Biological Diversity.¹ The second involved mapping the projected 2030 urban growth of 463 cities in the hotspots, identifying the conflict between sprawl and endangered species. The set of 463 cities was then reduced to thirty-three by selecting the largest and fastest-growing of these cities in each respective hotspot, the so-called ‘hotspot cities’.² Conservationists were then partnered with planners to represent these cities at a symposium at the University of Pennsylvania in June 2019 to share their experiences in regard to the conflict between urban growth and biodiversity occurring in their respective cities. In this third phase of the research, we take one of these hotspot cities, Bogotá, as a case study and_through a research-by-design process_ask whether conservation values and urban development can be symbiotic and how this can be explicitly reflected in the spatial planning of the city.

摘要

本文总结了哥伦比亚波哥大市城市发展与生物多样性相关的城市和区域规划案例研究。该案例研究是宾夕法尼亚大学麦克哈格城市主义与生态中心正在进行的研究项目的第三阶段_热点城市项目_。第一阶段涉及根据《生物多样性公约》对世界生物多样性热点地区的土地利用情况进行审计。¹第二个涉及绘制热点地区 463 个城市 2030 年的预计城市增长图，确定蔓延与濒危物种之间的冲突。然后通过选择每个热点中最大和增长最快的城市，即所谓的“热点城市”，将 463 个城市减少到 33 个。²随后，保护主义者与规划者合作，于 2019 年 6 月在宾夕法尼亚大学的一次研讨会上代表这些城市，分享他们在各自城市发生的城市增长与生物多样性之间冲突方面的经验。在研究的第三阶段，我们以其中一个热点城市波哥大作为案例研究，并通过设计研究过程来询问保护价值和城市发展是否可以共生，以及如何在空间规划中明确反映这一点城市的。
