Purpose: Since the 1960s, the impact of mega sporting events on the built environment has become increasingly important, and the relationship between hosting cities and events increasingly complex and controversial. The outcomes of these mega-events, however, are very discouraging, especially in terms of the state of sports venues and event sites. In many cases, Olympic parks and event sites stand abandoned once the event is over, and sports facilities are often either closed or underutilized. The purpose of this paper is to identify replicable best practices and successful examples used in mega-events to transform events sites and venues into livable public open spaces (POS), enjoyed by the local communities. Design/methodology/approach: Three cities were selected for this investigation: London, Sochi and Rio de Janeiro. London hosted the 2012 Summer Olympics, and this study focused particularly on its Olympic park, Queen Elizabeth Park. Sochi hosted the 2014 Winter Olympics but also some of the matches of the 2018 FIFA World Cup. Rio de Janeiro hosted the 2016 Summer Olympics and also a part of the 2014 FIFA World Cup. Each case was investigated according to a methodology composed of interviews with experts, site visits, and analysis of the bidding book and post-event reports to check the consistency between promises and legacies. Findings: The research identified a framework of six major elements that determine, or contrast, the long-term use of events sites and sport facilities, and highlighted some main attributes to consider in order to transform sporting event sites into livable and enjoyable open spaces. It is expected that this framework can be used as a guidance to deliver sustainable events and long-term legacies and to define a strategy for optimization of planning mega sport events. Practical implications: Mega events provide near-unique, fast track opportunities for urban transformation. This research can be used as guidance for the overall mega sporting events stakeholders, such as the IOC, FIFA, and local organizing committees, to identify replicable best practices and successful examples in the leverage of mega events to transform events sites and venues into livable POS. Originality/value: Why is it so difficult to transform event sites and sport venues into livable areas of cities? What are the recurrent mistakes, issues, and challenges that hosting cities have to face? This research is unique as it aims at answering these questions by defining a framework of relevant factors for hosting cities to help them in the planning of mega sporting events. The research also highlighted some recurrent mistakes, such as the exorbitant costs of a mega event, the inability to keep the initial budget unchanged and the difficulty to adjust plans to local needs.

The study investigates the legacies of the 2014 Winter Olympics, and, in particular, it focuses on the evaluation of the new public open spaces created after their stage and their sustainability outcomes. Indeed, Sochi was the second city, after London 2012, with a chapter dedicated to legacy in its candidature file. The study develops a post-occupancy evaluation of the Adler Olympic Park, the coastal cluster, and one of the main legacies of the Games. Findings highlight that the Games failed in the achievement of almost all the legacy promises made in the bid book.

With intensive emerging and transforming urban spaces and centres, the city of Doha is experiencing continual rapid growth. However, minor attention has been paid to important growth aspects. This paper examines functional, social and perceptual attributes of three urban open spaces in the city by developing and implementing a walking tour assessment procedure composed of checklists and a scoring system. Results reveal important outcomes including the absence of landscape features and a dearth of green spaces or appropriate outdoor furniture, the absence of adequate shaded areas and shading devices and parasols and a lack of children's facilities or a specially designated area for children among other missing elements. These represent shortcomings that impede the maximum efficient and effective utilisation of such spaces. The paper suggests that opportunities to concretise and fulfil people's needs in open spaces should be underscored by urban planners, architects and policy-makers in a multicultural rapidly growing city.
