Build covers with solar panels on their roofs. Provide shade and generate money in the long run. Most brick-and-mortar shoppers would be more attracted to covered parking, too.
It blows my mind that an article about shade deserts doesn't mention covering with solar collection systems. We all should expect anything intended to take sunlight should be a photovoltaic surface.
An increase in the number of solar cells in an area can be useful, but shade cover from trees would have a greater cooling effect on most areas. Trees both shade and provide transpiration cooling. The water evaporating from leaves cools the surrounding air as the water goes from a liquid to gas phase.
And just like solar panels, trees harvest a part of the energy in sunlight, giving additional cooling to just a shade. And trees are cheaper to set up, even if they may not provide a return on electricity.
Ideally you would have trees on the ground and solar panels on the roofs, to further increase cooling.
