If people investing in property in Dubai wonder what the emirate will look like in 30 years' time, a conference this month is set to reveal all.The vision of Dubai's city development, from sustainability to providing affordable housing, improving infrastructure and even branding, will be displayed at the Future Cities Conference and Expo on September 27th-29th.Held at Dubai International Convention and Exhibition Centre and organised by Dubai Municipality and Environmental Center for Arab Towns (ECAT), the future of Dubai will be unveiled in a presentation attended by a host of influential international delegates.Key to Dubai's future will be the ability to look beyond oil and gas, explained Mohammed Mahmood Al Noori, director of ECAT."Today, this sector contributes only four per cent to the UAE's GDP," he remarked. "Activities such as trade, transport, tourism, industry, finance and development of free zones have steadily developed over the years, making the UAE a more diversified economy."This proves that nurturing innovation across all industry sectors with a long-term perspective remains crucial for a country's progress."The conference will also discuss the development of a sustainable urban landscape as two-thirds of the world's population is expected to be living in towns and cities.
