Regional design, long a backbone for spatial planning, even if under other names, has become topical again for two reasons -as a key too for spatial strategy and as a key tool in spatial management. This is due to several reasons. New conditions of urbanisation that result from the convergence of several factors highlight the need for spatial strategy formation and application at supra-metropolitan scales. These new conditions include globalization and climate change along with all their impacts, as well as the urban population boom enabled by increased mobility and interconnectivity, along with new infrastructure technologies. These forces driving urbanisation today and into the future play out at a new urban scale, which is increasingly encompassed in the city-region. The solutions to the impacts and problems that these forces cause must be dealt with by urbanism at a scale that matches. Strategic solutions to this scale of urbanism can be denoted as regional design.Yet older factors, including those stemming from the problematic impacts of city-region growth and development that have remained unsolved for generations despite best efforts, still provide impetus for regional design. Factors such as housing affordability, socio-spatial inequity, traffic congestion, and air and water pollution, among others, have city-region sources and need holistic city-region wide solutions. These persistent factors also can be, and have been, effectively dealt with by regional design. This is because traditional urban planning, conceived at the neighbourhood, district, city, or even metropolitan scale are inadequate to deal with many pressing urban problems and opportunities today, and into the future. Often the causes of these problems arise at regional and even larger scales (Alawadi and & Benkraouda 2017,
