Being in a tropical country, I imagine most/all of your trees are non-deciduous, as in they don’t lose all their leaves in autumn and then regrow in the spring? Imagine all the leaves drying up, falling off, and the mess is left all over the ground. Cleanup is a laborious effort. Leaf blowers speed up the process by blowing the leaves from trafficked locations and/or to more centralized locations that are easier to clean the debris. Helpful, noisy, and often environmentally unfriendly.
Every new version of Civ, I hope they reintroduce live action advisors like the ones from Civ II.
