Revisiting Medellin's Governance Arrangement After the Dust Settled

Governance is a polysemic prescription for contemporary government and at an urban level has been instrumental in some radical and often striking reshaping of cities. This paper examines the interests and power structures behind those changes through the critical examination of the case of Medellin, Colombia, until recently a model of “good governance,” internationally acknowledged for its early millennium transformation from “murder capital to model city.” Based on extensive literature reviews and interviews, we unveil the forces underlying concrete governance practices. Major characteristics emerging from this perspective concern i) market hegemony, ii) the disempowerment of grass-roots movements and iii) the influence of illegal actors in the complex and shifting dynamics within and between the city's major players. The notion of both “good governance” and model practice are strongly revisited.

Identifying Storm Hotspots and the Most Unsettled Areas in Barcelona by Analysing Significant Rainfall Episodes in Barcelona During the 2013 – 2018 Period

Flash floods repeatedly threaten Barcelona, damaging the city infrastructure and endangering the safety of the population. The city’s urban planning and socioeconomic distribution, associated with the topography and other geographic factors, means that these flood events do not affect the entire city in the same way. This is a key point for surveillance and emergency tasks, which need some patterns and models to improve response capacity. This work aims to gain a better understanding of such events, to add valuable information on how to predict and manage these situations. For this purpose, both radar and ground observational data have been combined to identify the most important precipitation episodes in Barcelona between 2013 and 2018. To make the analysis easier, a new algorithm has been developed to determine the thunderstorm hotspots. Episodes with a higher impact have been analysed in depth. The final objective is to improve the actions taken by the organisation responsible for managing urban floods, which have seen Barcelona recognised as a model city for flood resilience by the United Nations.
