Generate shadows without trees: vegetable awnings, a new way to generate shadows in the city.

I found these kind of cool as an idea, as they can be added rather easily to existing cities and provide some greenery without taking up space, while providing shade:
If you built dense cities, like this you massively reduce land usage of cities. It also removes the need for cars and allows for easier sharing of many other resources. This means dense cities have a much lower carbon footprint then other forms of living. London for example has per capita emissions of 3.3t. Skyscrapers are not the best solution for density, but they work and in this case thats mid density housing.
This is a good way to have some greenery in a place, where planting a tree is difficult. This is a 6m wide street with shops on both sites, which is mainly used by pedestrians. If you plant a tree on the sites of the street, it does not get enough light. In the middle of the street it ends up blocking trucks from resupplying the shops, which is also not an option.
If you build dense cities, you don't need to build car infrastructures. You rely on walk, bike and public transport. You have plenty of space for trees and green spaces everywhere.
This is in the historic city center of Valladolid. So where can you remove car infrastructure so you can have trees everywhere? I am not talking about a park, but trees on a street to improve the micro climate and provide cooling.
I grow up next to an old medieval town. I'm not a stranger to how these towns are build. There are a lot of places where you can plant trees in the streets. Of course, the streets will be narrower with the place for just the pedestrians, bikes, and emergencies services. It's a fully car free town in this case. Your link is perfect. You have Pl. de España on the right where you could plant a small forest on it.
You see all the terrasses. They could have trees in the middle.
For this purpose of reducing the temperature, you have this project where they will keep a central bus stop but plant many trees to cover it.
That might be me having a bit of a skewd idea of what having trees everywhere means. Still too many cars though and obviously relatively new.
