Marina´s career as an architect started working and researching in leading daylighting strategies, specializing in day- and artificial lighting planning and then expanding to a sustainable holistic approach. Her latest work is based on the circular economy in the building sector.


On Monday, January 27, the LAI Madrid Chapter hosted its first luncheon in 2025. After the floodings in Valencia caused by the DANA a few months ago, our speakers were Jesús Arcos y Margarita Jover, director and co-founder by aldayjover arquitectura y paisaje, a leading landscape architecture office with a wide expertise in urban and building projects in floodable areas.

How can we transform an urgent need for flood mitigation into embracing an opportunity for creating urban space? How can we demystify the notion of catastrophe into the idea of improving the relationship between cities and rivers? Answering these questions, Jesús Arcos and Margarita Jover, exposed to the audience their approach as a multidisciplinary team, based on understanding the specific nature of the site, research and innovation, through some of their main projects.

What triggered our chapter to promote a conversation about floodability? The DANA caused an extraordinary episode of rainfall in Valencia in October 2024. Some sites recorded 771 l/m2 in 24 hours, of which 185 fell in one hour. The rainfall of an entire year concentrated in a few hours, the rainiest month on record according to the Spanish Ministry of Ecological Transition and Demographic Challenge. Together with this event, how many more places are being affected by increasing floodings and which solutions are urban planners and landscape architects providing?

aldayjover architecture y paisaje has been recognized internationally for its pioneering urban planning and projects in floodable urban areas along rivers, in which natural dynamics and floodings engage with public space and urban infrastructure. Authors of the Water Park of the Zaragoza International Expo 2008, with this project they burst on to the international landscape architecture scene. This land in the meander of the river Ebro is a first class example of transformation of a floodable area which was preventing the growth of the city in its direction, into one of the most visited parks of the city. It contains the necessary strategies for continuing being livable after recurrent floods, and for slowing the speed of the floodings into the city though the riverbed.
