#roofgardens

Around the world during the spring lockdown people noticed how slowly nature in cities returned. Venetians sighted dolphins from their balconies and Barcelonians huge swarms of butterflies.

So post-lockdown Barcelona decided it would not return to normal. As the city came to a halt wilderness had taken back the streets and park. The lack of gardening for one ensured that open spaces turned wild and were given back to their rightful owners: plants grew, insects danced and birds rejoiced but none more than butterflies that increased by 78% compared to the previous year.

“The lockdown gave us a glimpse of nature in the city and we liked it.”—Francisco Bergua president of the Spanish Association of Parks and Public Gardens (AEPJP),

Locals and city officials agreed that a return to normal was inconceivable, a more natural environment that embraces the city’s flora and fauna would mark the city’s post-covid comeback. Carratalá says Covid has forced us to look at nature in a different way. “It’s made us look at how we live and how we want to live,” he says. “There’s no going back from here.”

What the city is doing:

First off the city is creating 783,300 sq m of green open space including 49,000 sq meters of greened streets. Then it is encouraging bird and insect life by implementing 200 nesting towers for birds and bats, 40 beehives and 80 plantings designed as insect “hotels”. The council aims to educate the populace with an atlas listing of the city’s wildlife and plant species.

“It’s not just having a park surrounded by asphalt but introducing nature into the city. People need re-educating. Their idea of a clean space is somewhere where there’s no life, where the ecosystem is dead. There’s this idea that nature is something outside and that what’s natural for the city is for there to be nothing.”—Lorena Escuer, Hydrobiology

For officials it is important that residents realize that Rewilding isn’t simply a way for the city to cut gardening costs but rather a thought out plan to thoughtfully naturalise the environment—making it healthier for us all.

“Naturalising the city isn’t the same as making it a wild space,” says Bergua. “But instead of parks and gardens we need to think in terms of green infrastructure. Doing the same thing in a different way.”

What locals are doing:

Architect Sergio Carratalá, founder of MataAlta Studio, has created roof gardens on 6 buildings with 10,000 native perennials that are both pollinator friendly and drought resistant—providing flowers for food and nesting places for birds. To irrigate the garden rainwater is collected and pumped throughout the garden via solar power. Once completed, the project will provide the building with a wonderful slice of nature for its 200 occupants.

Why more cities should follow:

This novel approach to city “gardening” showcases the city’s commitment to conserving its biodiversity. The scheme would also save water, energy, and money—becoming more sustainable. We’ve all felt how spending more time in nature heals us, even just “earthing” can improve our mental states. So wouldn’t it be great if more cities took the initiative to rewild? Bringing us back home—more in tune with our inner and outer selves.
