Too much concrete not enough shade?

praya in sun
Walking along the Praya around midday today - when it was hot with intense sun - I was again struck by the expanses of open areas with bricks and/or concrete, with little shade.

I know it's not easy growing trees along the waterfront - tropical storms and typhoons sometimes come along and bash them down. But open areas like this seem designed for robots rather than humans - maybe by people in somewhat remote, air-conditioned offices, who rarely or never walk here.
square in sun
Even at this  relatively new "square" there is minimal shade - again, by designers in love with concrete, who added a splash of greenery (but note: people must keep off the grass).

Here, by contrast, pople are relaxing under a couple of big old shade trees.
