Challenges of mainstreaming green infrastructure in built environment professions
© 2019, © 2019 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group. Green infrastructure (GI) has been identified as a promising approach to help cities adapt to climate change through the provision of multiple ecosystem services. However, GI contributions to urban resilience will not be realized until it is more fully mainstreamed in the built environment and design professions. Here, we interrogate five key challenges for the effective implementation of GI: (1) design standards; (2) regulatory pathways; (3) socio-economic considerations; (4) financeability; and (5) innovation. Methods include a literature review, case studies, and interviews with resilience managers. We propose a people-centred and context-dependent approach to advance effective implementation of GI in urban planning. We highlight two underlying currents that run across all of the challenges–(1) the role of political will as a pre-condition for tackling all challenges holistically; and (2) the role of stakeholder engagement in achieving public support, harnessing funding, and maintaining and monitoring GI in the long term. Highlights: • The effective implementation of GI is context-specific and should adhere to the basic principles of appropriate technology. • Continuous community engagement is needed to ensure the inclusivity and multi-functionality of GI. • Challenges to successful GI are intersectional and therefore cannot be addressed singly in isolation
Earth observation for sustainable urban planning in developing countries: needs, trends, and future directions
Abstract: Cities are constantly changing and authorities face immense challenges in obtaining accurate and timely data to effectively manage urban areas. This is particularly problematic in the developing world where municipal records are often unavailable or not updated. Spaceborne earth observation (EO) has great potential for providing up-to-date spatial information about urban areas. This article reviews the application of EO for supporting urban planning. In particular, the article overviews case studies where EO was used to derive products and indicators required by urban planners. The review concludes that EO has sufficiently matured in recent years but that a shift from the current focus on purely science-driven EO applications to the provision of useful information for day-to-day decision-making and urban sustainability monitoring is clearly needed
Strategies for the Reuse of Vacant Urban Land: Herron Avenue and Brighton Road
This project deals with an issue that is prevalent in many American cities: what is to be done with excess private and public properties throughout our cities - with special emphasis on former commercial corridors. Through the medium of two case studies in separate neighborhoods of the City of Pittsburgh, the project examined both the opportunities and the challenges to redeveloping vacant urban land. The goal of the project was two-fold: 1) to develop realistic proposals to address the specific needs of these two distinct neighborhoods and, 2) to develop prototypes that could be applicable to other cities and communities. Because the issues involved are so common to many other communities, the conclusions should be applicable as well.</p
