And commercial development in suburban locations can often impact on the economic strategies of the city. The city hinterland also supplies essential services, such as the supply of food and drinking water, flood management, and waste disposal. So, city governments need to take an interest in land outside the city boundary' - if possible to deter urban sprawl, development that may increase flood risk and the need for transport infrastructure. Equally, local governments outside the city need to reflect how the development of the urban area will place demands on their plans and land use. David Audretsch’s book, Everything in its Place, sets out a framework for strategic management of growth in a place-based approach, but across multiple places, big and small, how' can development planning help to avoid unwarranted externalities and thus achieve the best overall outcome in use of land? How could the national need for sufficient new homes be reflected in the totality of local plans, while (reflecting the views of those who elected them) local planning authorities were reluctant to designate sufficient land to deliver a “fair share”?
