Were those private lands/properties? Because in my country a lot (if I can't say 'most') are actually on public land with weird and disgustingly cheap leases which can be closed at a finger snap but somehow very few Govts have tried it because every Govt have ministers (and of course bureaucrats) who are members there or made members there, and then there are their kids and families etc. So no they can't be turned into building constructions really, I mean assuming the limits of corruption in my country. Because technically anything can be sold if we go down that way. Also, my city is reclaiming lakes, demolishing illegal constructions and parks are also being reclaimed and cleaned up etc.
Not perfect, far from it, but it's a start and no, that Amazon Warehouse thing I am not expecting to see here. People are divided strongly on religious and ideological lines here but everyone's tempers run high whenever Govt tries touching a public land, green patch, and now we just take matters into our hands whenever that happens.
It’s private land.
There are a handful of government owned golf courses (sort of like parks that have tennis courts), but they are not common.
