Book excerpt: Creative solutions for global cities addressing their urgent homeless crises. This book takes on perhaps the most formidable issue facing metropolitan areas today: the large numbers of people experiencing homelessness within cities. Four dedicated experts with first-hand experience profile ten cities—Bogota, Mexico City, Los Angeles, Houston, Nashville, New York City, Baltimore, Edmonton, Paris, and Athens—to explore ideas, strategies, successes, and failures. Together they bring an array of government, nonprofit, and academic perspectives to offer a truly global perspective. The authors answer essential questions about the nature and causes of homelessness and analyze how cities have used innovation and local political coordination to address this pervasive problem. Ten Global Cities will be an invaluable resource not only for students of policy and social work but for municipal, regional, and national policymakers; nonprofit service providers; community advocates and activists; and all citizens who want to collaborate for real change. These authors argue that homelessness is not an insurmountable social condition, and their examples show that cities and individuals working in coordination can lead the charge for better outcomes.
