Specialized industry without pollution - Documentation wrong resp. incomplete

[MB]

I was somewhat irritated about the specialized industry types "farming" and "forestry" (without industries DLC!):

• The handbook (both German and English) states that forestry has a 7% increased pollution over generic industry.
  
• The info window in the Game for industry zone types shows some advantages and disadvantages but doesn't say anything about pollution. Neither does the short explanation in the city milestone window.
  
• In a video I saw another version of the info windows where it was stated that both farming and forestry do not create any pollution. (That was when I got confused...)
  
• Testing it out in the game yields the result that indeed they have no pollution at all! (The cause noise pollution, but do not pollute soil or water.)

So the handbook is actually misleading (probably outdated) and the info window is missing a very important information about these two industry types. It turns out that both specialized industry types are preferable over the generic industry. And forests for forestry can even be created by planting lots of trees!

The downside of this is that without generic industry, specialized industry don't have customers in the city and they export everything. This causes more heavy traffic than what is ideal if you just keep growing specialized industry and don't do generic at all.

Noise pollution affect the surrounding too . If you don´t care about and build residentials nearby , you´ll have issues like sick people and abandonned buildings

Thanks for your tips.

> Noise pollution affect the surrounding too.

I am aware of this and account for it with a forest buffer zone around industry districts. But it affects all industry, so in comparison the specialized farming/forestry industry seems better imho.

> This causes more heavy traffic ...

Agreed, I noted that such industry creates truckloads going in and out of the city creating much traffic. I haven't studied if there is more traffic than with generic ones though.

Anyway, I intuitively mixed specialized and generic industries 50:50. Not sure if this is perfect - I don't care much about import/export - but it certainly works for me and keeps soil pollution low overall.

P.S. The industrial waste recycling policy (from Green Cities DLC I believe) also helps reducing pollution a but, once it is available and applied.

Being concerned with land pollution I think to try to reduce the size of generic district. They require all four specialized materials to function to produce goods for sale or export. So if you reduce to the point of goods are required from imports then that might too little of a district, but I'm not the mayor. You can also import all goods doing away with generic industry and use forestry and farming and offices for work force and if you are using GreenCities IT Clusters. Though this idea requires a good import/export infrastructure to lessen traffic volume.

I legit didn't know this until just now, 200+ hours in. It makes sense, I just don't recall them ever complaining they weren't getting raw resources so I never thought were they got material to build with. I thought they just created them on site. Well that's a good reason to have all industries then I guess lol. I thought it was mostly cosmetic to give the city variety.

It's more 4:1 as there are 4 specialized industry. But I think each specialized industry only needs to be about 25% of Generic Industry. so its' a 1:1 final ratio.
