Losses due to inefficiency

What can i do to make the losses due to inefficience less ?
Some towns has between 250 and 300 losses per hour for some productions.

Thanks and regards.

Increase your food production by upgrading your food plots and using artifacts. Spread out your units to other towns. Reduce corruption by removing towers and other useless buildings. You need to use strategy and focus on how many of each things to build and train. Not just max out as many possible towers and units you possibly can.

Another way is removing 1 out of your 4 towns but it might not be good way

If you are talking about the corruption mechanic, where starting with your third town you start losing 10%  (and +10% more for every town you found past that) of your resource income, culture output, and science output.

They only things that reduce the effects of it are special buildings, and certain effects on hero items (the item effects only work in the town the hero is in though).

The buildings are:

Courthouse (Late Medieval) for Resource income.

Conservatoire (Mid renaissance) for Culture.

And the Observatory (semi-late Industrial) for Science
