Welcome to On Verticality. This blog explores the innate human need to escape the surface of the earth, and our struggles to do so throughout history. If you’re new here, a good place to start is the Theory of Verticality section or the Introduction to Verticality.

The Altitudinal Decrease in Vegetation

Pictured above is an illustration from the 1860s by Jean-Augustin Barral, titled Décroissement Altitudinal de la Végétation, which is French for The Altitudinal Decrease in Vegetation. It’s a beautiful work that attempts to categorize vegetation types by elevation, which is known as altitudinal zonation. Barral gets the overall concept correct, but we now know the details to be much more nuanced and complex than his drawing suggests.

Altitudinal Zonation : Mountains and Verticality

The earth’s atmosphere is defined by vertical gradients. As one rises, the air thins out, humidity decreases, and temperatures drop. It’s why we get altitude sickness when we travel to high places, and it’s why the tops of very high mountains are snow-capped. These vertical gradients are defined by altitudinal zonation.

Forests and Verticality

The progression of forest growth over time is based on access to and competition for sunlight. This process is based on Verticality. As a plant grows taller, it casts a shadow on everything below its foliage, hindering the growth of smaller plants below. This process can be found throughout the natural world, and it follows a pattern of regrowth called plant succession.

Terracing and the Green Machine

Making meaningful green spaces in high places

Two things that every human being needs are to escape the surface of the earth through Verticality, and to be around plants and vegetation. Ever since the beginnings of permanent shelter and architecture, humans have been attempting to escape the surface by creating and inhabiting high places. We’ve also been repeatedly trying to recreate the experience of the surface by linking these spaces with greenery.

Bologna Rising

Here's a forest of towers in the Italian town Bologna, from the early 20th century. These towers were built as extensions of private homes for wealthy families. Their exact purpose isn't quite clear, but most likely it was a combination of status symbols and as means of defense during uncertain times. The image is quite compelling, with the forest of needle-like towers poking out above the lower buildings of the town below.

Verticality, Part III: Inception

Our first act of descension and our first act of ascension

Our species evolved within the context described in Part I, and our physical surroundings would provide the foundation for our struggles with Verticality, as described in Part II. These early struggles would be defined by two acts. The first is an act of descension: we came down from the trees and out onto the savannah to become surface-dwellers. We would still carry much of the baggage from tree-dwelling life with us, however. I’ll henceforth refer to this baggage as our source-code. The second is the shift to bipedalism, resulting in our upright, vertical bodies. Together, these two acts would set the stage for the future and our never ending struggle to escape the earth’s surface.
