Introduction Juan M. Barrionuevo, Pascual Berrone and Joan E. Ricart are of the opinion that over 50% of the world’s population lives in cities and urban areas, if the current trends of rural-urban migrations are anything to go by; this is set to shoot over 75% by the year 2050. (Barrionuevo, Berrone, & Ricart, 2012 p. 51) The number of densely populated areas in cities will increase complicating urban mobility and putting greater strain to public facilities, this calls for cities to employ mechanisms to accommodate the large population, in what is referred to as “Sustainable Development.” In their article, “Opportunities for Urban Development, smart cities sustainable progress” (Barrionuevo et al, 2012 p. 50-57) lists Rio de Janeiro, Barcelona, Yokohama, Malaga, Singapore, Birmingham, Copenhagen, Eindhoven, Suwon, and NYC as the world’s smartest cities. They however fail to quote Masdar as one of the smart cities. Therefore, the main goal that defines the discourse of this paper is to evaluate Masdar city in the light of the factors of sustainable development of smart cities as stipulated by (Barrionuevo et al., 2012 p. 52-55) This paper is divided into two parts; the first part is an in-depth analysis of Masdar city in the light of factors of sustainable development as presented by (Barrionuevo et al, 2012 p. 52-55), the second part seeks to establish whether the technology triangle has a role to play in the sustainable development of Masdar City. Sustainable Development of Masdar City Economics; the Masdar Institute of Science and Technology is leading research in IT and biotechnology, this is set to attract multi-global companies to invest in the city boosting its economy. Global companies in renewable energy and sustainability are already relocating to Masdar City. It hosts the International Renewable Energy Agency (IRENA) which attracts investment thus boosting the city’s economy Mobility and transportation; there is a pilot project of electric vehicles at Masdar Institute, electric cars and buses are set to be the means providing public transport in the city. Connection to the extensive metropolitan area will be provided by the light rail of Abu Dhabi and Metro lines which are set to pass across the city. Urban planning; renewable energy sources with low relative environmental impact are used, the buildings’ orientation to the sun and winds are set in a way that the city is dominated by cooler temperatures. It employs narrow streets whose orientation maximizes shade at ground level. The entire city is built on a 23 foot-high concrete base to maximize exposure cooling winds. Environment; the city is fully powered by on-site renewable energy, generates photovoltaic electricity and taps solar energy via solar collectors. It capitalizes on the resourcefulness of waste by , recycling, re-using, composition and recovery of energy. It encourages a public transport system to reduce co 2 emissions, wastewater is treated and reused for landscaping. Governance and civic participation: The city presupposes a democratic political system and established civil societies Social cohesion: Technologically the city has adopted fiber optics and technologies that control traffic and ambulance services from a central point. As part of the social cohesion plan, the city’s buildings are built based on traditional Arab homestead architectures. International
