     It was widely reported last year that sales of guidebooks are falling fast, thanks to developments in the Internet and mobile phones. It makes sense. Why bother taking a heavy book with you when you can down all the information you need to your phone as you walk around the cathedral? 

     Writing a new book about a place is a rewarding job, but one that is becoming a rarity. Publishers are more concerned with keeping existing books up to date than bringing out new ones in an already crowded market. This is understandable, since every guidebook is actually out of date as soon as it is published. It may have been researched a year before being printed and it could have sat on the bookshop shelf for a year or two, so its information might be three years old by the time the reader uses it in practice. It is hardly surprising, therefore, that some publishers are inviting almost as much in updating and redesigning their books as they did creating them. Updating guides is nowadays a good way for new writers to get started. 

     But if the Internet via a mobile phone can deliver information just as well as printed paper but much faster, at almost no cost, is there a future for printed guidebook? Other books you read at home, but a travel guide's main purposes for urgent reference when you're desperate to find accommodation or somewhere to eat. Using a modern cellphone, any traveller can now enjoy a “paperless holiday”. Want to know the opening times of the museum? Look them up online.

     It is estimated that by 2050 more than two thirds of the world's population will live in cities, up from about 54 percent today. While the many benefits of organized and efficient cities are well understood, we need to recognize that this rapid, often unplanned urbanization brings risks of profound social instability, risks to critical infrastructure, potential water crises and the potential for devastating spread of disease. These risks can only be further exacerbated as this unprecedented transition from rural to urban areas continues. 

     How effectively these risks can be addressed will increasingly be determined by how well cities are governed. The increased concentration of people, physical assets, infrastructure and economic activities mean that the risks materializing at the city level will have far greater potential to disrupt society than ever before. 

     Urbanization is by no means bad per se. It brings important benefits for economic, cultural and societal development. Well managed cities are both efficient and effective, enabling economies of scale and network effects while reducing the impact on climate of transportation. As such, an urban model can make economic activity more environmentally-friendly. Further, the proximity and diversity of people can spark innovation and create employment as exchanging ideas breeds new ideas. 

     But these utopian concepts are threatened by some of the factors driving rapid urbanization. For example, one of the main factors is rural-urban migration, driven by the prospect of greater employment opportunities and the hope of a better life in cities. But rapidly increasing population density can create severe problems, especially if planning efforts are not sufficient to cope with the influx of new inhabitants. The result may, in extreme cases, be widespread poverty. Estimates suggest that 40% of the world's urban expansion is taking place in slums, exacerbating socio-economic disparities and creating unsanitary conditions that facilitate the spread of disease. 

     The Global Risks 2015 Report looks at four areas that face particularly daunting challenges in the face of rapid and unplanned urbanization: infrastructure, health, climate change, and social instability. In each of these areas we find new risks that can best be managed or, in some cases, transferred through the mechanism of insurance.
