- ItemNavigating Climate Change Challenges through Smart Resilient Cities: A Comprehensive Assessment Framework(MDPI (Basel, Switzerland), 2024-03) Khatibi H; Wilkinson S; Sweya LN; Baghersad M; Dianat H; Giorgi E; Garau C; Venco EMThe rapid increase in the global population is contributing to the urgent challenges we face in ensuring the sustainability of our planet. This demographic shift, which gained momentum in the 1990s, is closely linked to a surge in natural disasters, both in terms of their frequency and severity. The quest for resources and improved quality of life, including the need for housing and essential services, has compounded these challenges. With the world’s population projected to double by 2050, and approximately two-thirds of this population expected to reside in urban areas, we are facing a complex web of interconnected issues that will significantly magnify the impacts of climate change-induced disasters. It is imperative that we build resilient cities capable of withstanding and adapting to these changes. However, the growing complexity of urban services and the necessity for integrated management raise questions about the preparedness of these resilient cities to comprehend and address the multifaceted challenges posed by climate change. In response to these critical concerns, this study endeavors to address the intersection of resilience and climate change. We propose the development of a Smart Resilient City Assessment Framework, comprising two core components: resilience re-evaluation and smartness evaluation. Each component consists of eight essential steps. The culmination of these steps results in a semi-quantitative index that accurately reflects the city’s position regarding resilience and smartness in the face of climate change-related disasters. To demonstrate the framework’s practicality and suitability, we present results from a hypothetical scenario focusing on water supply management, a critical aspect of climate change adaptation. The framework equips city managers with the necessary tools to re-evaluate their cities’ resilience, evaluate their capacity to address climate change-induced challenges, and make informed decisions on integrating resilience and smart solutions to pave the way for a more sustainable and climate-resilient future.
- ItemTool development to measure the resilience of water supply systems in Tanzania: Economic dimension.(AOSIS Publishing, 2021) Sweya LN; Wilkinson SThe world has experienced devastating disasters causing severe human life and economic losses, which is estimated to be 68.5% of the global economic losses between 2005 and 2017. Natural disasters are of great concern - they caused total damage of approximately $3.5 trillion during the past century - which is more than the global infrastructure development investment in 2014. Floods - exacerbated by climate change - are expected to cause more damages, and water supply infrastructures will continue to suffer if resilience is not improved. Measuring the economic changes affecting resilience would assist in developing risk reduction initiatives to minimise disaster losses. Such a measure is lacking for Tanzania water supply systems (WSSs). The current article applied three-stage processes - literature review, pre-assessment and Delphi technique - to develop a resilience tool to measure economic resilience for urban WSSs in Tanzania. Thematic and standard descriptive analyses were carried out during the study. Dynamism principle and three indicators - system investment proportionality, public-private partnership and cost recovery - emerged as principal components for the tool. The tool is expected to be useful during water authorities' planning processes and budgeting in order to improve the overall WSSs resilience.
