I live in Mexico City and a large part of this is the odd compulsion that chilangos have to put concrete over absolutely everything. It rains but there is very little unpaved surfaces to absorb any of that water and return it to underground sources. I've had friends and family members inexplicably rip out nice gardens at their houses and replace it with paved surfaces. My in-laws have a large yard that only has a few square meters of unpaved ground left. My street has flooding problems during intense rains every couple years in large part because no water can be absorbed anywhere and if the small street drains get clogged with branches it is a disaster.

The choices are either pavement or grass. Open ground creates dust and mud.

The reason why 1st world cities look "cleaner" is because every single sq inch is either paved or turfed with grass.

Xeriscaping is a thing. Also are other greenery options than grass. We had a dust/mud patch, but then planted 100% clover (by simply throwing seeds on the ground). Now we have completely unmanaged greenery. It's not neat, we don't even water it - it's green in the spring, golden/brown in other seasons. Easy peasy.
