About thirty years ago, French landscape architect Patrick Blanc became a pioneer in the implementation of vertical gardens in Paris, and later in other cities around the world. Through the creation of vertical structures capable nourishing plant species, these systems allow species to grow on the facades of buildings, considerably reducing a structure's internal temperature and allowing the expansion of green areas to new (vertical) territories within the city.
Blanc's creation was part of a series of developments in understanding what nature adds to the city, recognizing the value of green spaces and their contribution to social, environmental and urban policies.
