Urban diversity: necessity and strategies

Abstract

This paper explores the necessity of maintaining diversity in cities. Diversity has been proven to be a driving force in ecosystem health in natural settings, where resilience against unpredictable perturbations is essential. Economic, social, and biological diversity is of prime importance in urban settings, where inevitable changes may challenge even the most prosperous human environment. Diversity contributes to urban fabric, it ensures long-term resilience, and it enhances sustainability. However, the pressures and expedients of economic and physical growth tend to obfuscate the importance of diversity. Balancing development with growth, maintaining a broad economicbase, preserving history, and nurturing appropriate green spaces all contribute to urban diversity. I will discuss several examples of North American cities that “should have known better” as a way to explore solutions that enhance urban diversity.
