“…Recently, studies have discussed the requirement of fundamental shift to implement solutions to climate-resilient development and a sustainable urban environment (Cousins 2024). In cities across the world, nature-based solutions are gaining importance as promising solutions in local and global agendas, that enable spatial-specific urban sustainability and climate resilience development (Gulsrud et al 2018, Adams et al 2024. How spatial urban planning can help to achieve sustainability has been identified as a research gap in most developing cities.…”

Hawassa characterizes a typical developing city in Ethiopia, owning to rapid urban growth and demographic trends. The combined effect of climate change and urban expansion is increasing the challenge to the environment and the services it provides. Relating changing environments with urban water management (UWM) is required to build resilience in the urban environment. This research analyzed local climate change and urban growth and linked it to UWM. The historical period 1990–2021 of daily rainfall, temperature variables, four satellite imageries, and DEM were analyzed. Changes in rainfall (annual and daily maximum) and temperature (maximum and minimum) trends are detected and projected to 2051 using a statistical-based model. With geospatial techniques sub-watersheds are delineated, and the urban cover change is quantified. The trend detection result implies an upward trend of annual and daily maximum rainfalls however a significance is insufficient (p > 0.05) to associate it with climate change during the study period. Maximum and minimum temperatures change indicate a positive and significant trend. The forecasting result suggests an increment of both temperatures (0.5 °C–1.5 °C) to the projected period compared to historical scenario. The land cover analysis results show the built-up area changed from 11.6 km2 (7.2%) to 42.5 km2 (26.5%) during the historical period, where the rate varies spatially. The surface runoff increased by 30.7% in the urban watersheds. With a growth rate of 8.9% built-up, the urban area will cover 73.6 km2 (45.9%) for the predicted period. The research finding justifies the potential to reorganize the relationship between the spatial effect of climate change and urban growth on UWM. Considering distinct characteristics of urban watershed, exposure to flooding risk, access to water demand and resilient to climate change have spatial variation. Thus, a local-specific planning approach will support effective UWM and climate adaptation for sustainable city development.

Theory and Practice of Urban Sustainability Transitions

Change is needed in how cities are designed, built, and managed to meet the grand challenges of the twenty-first century. In this book, we invited authors to report on their visions for cities, using a missions-oriented perspective on transformative innovations that support more liveable, sustainable, resilient, inclusive, and just futures. The resulting chapters have proposed a set of distinctive missions, providing what we think can provide the primary focus for future urban research and sustainability efforts. However, the chapters provide a mosaic rather than a single unified vision. To weave them together, this introductory chapter provides a conceptual framework for connecting and operationalising the mission-oriented approach for urban development research as a nexus of imaginaries, missions, pathways, and transformative urban innovations. This allows for orienting and bringing together contributions that represent a forward-looking collection for missions to guide and inform future city-making. In this chapter, we identify the pathways, game changers, and positive tipping points that can reshape future cities. This requires conceiving and activating multiple mission-scale programmes of intervention capable of step-change urban transitions.
