>>1317541>Directly ask the scientists.
that is what happens in the bundestag panel sessions. maybe i was not sufficiently clear, but one thing is the general discourse, and another one the political process. they feed into each other but are not the same. the panel members invite various experts, chiefly among them scientists in the given fields, and ask for their input, comments, and reports. >MdBs are the least qualified people for that in the entirety of Germany.
that is not necessarily true. the incessant bitching, yapping, and moaning about politicians is a bit of a default mode for the uninformed parts of the populace. it must be said that most MdBs only have one field they specialize in, but when they do, when they do it over years, they're good at it. take matthias gastel and his focus on (railway) transportation, highly respected both in the political field and beyond. not my party preference, by the way.
also: politicians have staff, and both they and their MdBs have access to the scientific services (wissenschaftliche dienste) of the bundestag. the services are elite at what they do.
by the way, the least qualified MdBs by far are from the AfD. it's not even a badly kept secret anymore.
but i don't want to suggest that aspects of urban planning are generally decided on the federal level. the matter of urban planning is still chiefly negotiatated on the state and municipality levels. while the state level can regulate the legal framework (including certain stipulations), the actual execution happens in the towns and cities. the #1 condition for quality in local urban planning is having a capable local building authority, solid decision makers and an inspired city council.
