The document outlines the Community Sustainability and Resiliency Special Initiative (CSR SI), which aims to facilitate sharing of urban environmental and societal data, information, and tools. The CSR SI has established an international forum for urban practitioners and policymakers to share best practices. Its expected outcomes within 5 years include building a common knowledge platform, connecting urban professionals globally, increasing capacity to use geospatial data/tools, and providing value to policymakers. Projects under the initiative work on developing frameworks and datasets to support urban planning and management.
